A Paleolithic elimination diet (Wahls diet) or a low-saturated fat diet (Swank diet) are associated with improved cognition, among other clinical outcomes, in relapsing-remitting multiple sclerosis (RRMS), new research suggests.

In a randomized study of patients with RRMS, the group that followed a Wahls diet and the group that followed a Swank diet both showed significant, unique improvement in measures of cognitive dysfunction, fatigue, and quality of life.

“Several dietary intervention studies have demonstrated favorable results on MS-related fatigue and quality of life. However, these results are among the first to show favorable reductions in cognitive dysfunction,” said co-investigator Tyler Titcomb, PhD, department of internal medicine, University of Iowa, Iowa City.

The results were presented at the 2021 Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC).
 

Similar diets

The CMSC findings came from a secondary analysis of a randomized trial published online in July in the Multiple Sclerosis Journal Experimental, Translational, and Clinical (MSJ-ETC).

The primary analysis of the single-blind, parallel group, randomized trial showed the Wahls and Swank diets were linked to significant improvement in outcomes on the Fatigue Severity Scale (FSS), the Modified Fatigue Impact Scale (MFIS), and other measures among participants with RRMS. There were no significant differences between the two dietary regimens.

The Swank diet restricts saturated fat to a maximum of 15 g per day while providing 20 g to 50 g (4 to 10 teaspoons) of unsaturated fat per day, with four servings each of whole grains, fruits, and vegetables.

The Wahls diet recommends six to nine servings of fruits and vegetables per day, in addition to 6 to 12 ounces of meat per day, according to gender. Grains, legumes, eggs, and dairy, with the exception of clarified butter or ghee, are not permitted on this diet. Both diets eschew processed foods.

To further evaluate the diets’ effects on perceived fatigue and cognitive dysfunction, the researchers returned to the trial, which enrolled 95 adults with stable RRMS at the University of Iowa Prevention Intervention Center between August 2016 and May 2019.

After a 12-week run-in period with support and education from registered dietitians, participants were randomly assigned to either the Swank or Wahls diets in a 24-week intervention that did not include dietitian support.

Inclusion criteria included having moderate to severe fatigue, as shown by an FSS score of at least 4.0, while not having severe mental impairment, an eating disorder, or liver or kidney disease. There were no significant differences in baseline demographic or clinical characteristics between the groups.

Of the patients, 77 completed the 12-week run-in (38 in the Swank diet group and 39 in the Wahls group). A total of 72 participants completed the 24-week follow-up (37 and 35, respectively).
 

Reduction in fatigue, cognitive dysfunction

After the researchers controlled for smoking, alcohol consumption, age, sex, baseline distance 6-minute walk test, body mass index, serum vitamin D, and years with MS, results at 12 and 24 weeks showed significant improvements from baseline in the key outcomes of fatigue and cognitive function, as measured by the Fatigue Scale for Motor and Cognitive Function (FSMC).

Scores were −5.7 and −9.0, respectively, for the Swank diet group and −9.3 and −14.9 for the Wahls group (P ≤ .001 for all comparisons).

In addition, there was a significant reduction in both groups on the total Perceived Deficits Questionnaire (PDQ) at 12 and 24 weeks (Swank, −7.4 and −6.3, respectively; Wahls, −6.8 and −10.8; P ≤ .001 for all).

There were similar improvements for both diets in an analysis of the mental and physical scores on FSMC and on the subscales on PDQ of attention, retrospective memory, prospective memory, and planning.

As observed in the primary analysis, there were no significant differences between the two groups in absolute mean scores on FSMC, PDQ, or their subscales at any timepoint.

“Both diets led to significant reductions in fatigue and cognitive dysfunction,” Dr. Titcomb said.

Of note, the primary analysis further showed statistically and clinically significant increases in the 6-minute walk test at 24-weeks of 6% in the Wahls group (P = .007). After removal of nonadherent participants, the improvement was still significant at 24 weeks in the Wahls group (P = .02), as well as in the Swank group (P = .001).

Dr. Titcomb noted that the majority of study participants were taking disease-modifying therapies (DMTs). However, there were no interactions between any specific DMTs and dietary benefits.
 

Potential mechanisms

Although the similar outcomes between the diets point to a common mechanism, there are also various other possibilities, said Dr. Titcomb. These include modulation of the microbiome, inflammation, immune system, or micronutrient optimization, he said.

Previous research has shown reduced mass and diversity in the gut microbiota among patients with MS compared with those without MS, potentially promoting inflammation. Other research has shown improvements in those factors with dietary modification.

While there is no evidence of gut microbiota changes with the Wahls and Swank diets, each is rich in fiber and plant-derived phytochemicals, which are known to be associated with improvements in gut microbiota and neuroinflammation, the investigators noted.

Dr. Titcomb reported that research into the diets is continuing as they evaluate longer-term and other effects. “This trial was a short-term parallel arm trial that did not include MRI or a control group,” he said, adding that the investigators will soon start recruiting for a follow-up study that will include a control group, long-term follow-up, and MRIs.

That upcoming study “has the potential to answer several of the unknown questions regarding the effect of diet on MS,” Dr. Titcomb said.
 

Notable research with limitations

Commenting on the study, Rebecca Spain, MD, MSPH, associate professor of neurology at the Oregon Health & Science University, and associate director of clinical care at VA MS Center of Excellence West in Portland, said there were several notable findings.

This includes that most people with MS “were able to adhere to the protocols for significant lengths of time, even without the support of dietitians for the final 12 weeks of the study,” said Spain, who was not involved with the research.

A significant limitation was the lack of a control group. Without that, “it’s hard to know for sure if the improvements in fatigue and cognition were from the diets or were simply from the social support of participating in a research study,” she said

Nevertheless, trials reporting on dietary effects in MS such as the current study are important, Dr. Spain noted. They demonstrate “that it is feasible and safe to conduct dietary studies and suggest which key MS symptoms may benefit and should be evaluated in future studies.”

“Critically, diet studies address one of the most frequent concerns of people with MS, promoting self-management and empowerment,” Dr. Spain concluded.

General guidelines for common dietary elements with evidence of improving fatigue, cognition, and mood are available on the National MS Society’s website.

The study received no outside funding. Dr. Titcomb and Dr. Spain have disclosed no relevant financial relationships. Terry L. Wahls, MD, who developed the Wahls diet, was a senior author of the study.

In the study by Aggarwal et al., the investigators evaluated whether molecular subtypes as identified from biopsies of metastatic tumors in patients with metastatic castrate resistant prostate cancer (mCRPC) could result in improved prediction of response to therapies. In this retrospective study of 4 distinct cohorts, 45% of tumors were classified as luminal and 55% were classified as basal. Luminal tumors exhibited increased expression of androgen receptor pathway genes, and patients with luminal tumors had better survival after treatment with ASI compared with those with basal tumors. Genomic analyses of mCRPC metastases are challenging due to processing issues that can arise if bone decalcification needs to be done; therefore, this study provides an important next step to aid in the design appropriate clinical trials to investigate whether such genomic subtyping results in improved patient outcomes.

            In the study by Saad et al, the investigators evaluated whether the addition of the androgen receptor inhibitor apalutamide added to abiraterone would result in a higher radiographic progression free survival (rPFS) compared with abiraterone alone in patients with mCRPC. The combination resulted in an improvement in rPFS (24 versus 16.6 months); however, there was no improvement in overall survival. These results are similar to the Alliance A0321201 study, where enzalutamide was added to abiraterone, and no overall survival was observed. Further study is needed to determine if this combination strategy can work.

            Supportive care aside from ASIs or chemotherapy directed against prostate cancer is also of critical importance to patients with metastatic prostate cancer. Previous studies have demonstrated that BMAs, such as denosumab or zoledronic acid, result in the prevention of skeletal-related events (SREs) in patients with mCRPC. However, this same benefit has not been demonstrated in metastatic castrate sensitive prostate cancer (mCSPC); therefore, BMAs are not recommended in this population unless they are at high risk for osteoporotic fracture. Mitchell et al. evaluated a retrospective cohort identified from Surveillance, Epidemiology, and End Results (SEER)-Medicare data to determine the number of patients with likely mCSPC treated with a BMA (defined as prescribed a BMA within 180 or 90 days after initial diagnosis of metastatic disease). A significant number of patients with likely mCSPC were prescribed BMAs within 180 days of diagnosis (23.6% of the cohort) and within 90 days (18.4% of the cohort). It is likely that most of these patients inappropriately received BMAs and were potentially subject to unnecessary costs and toxicity. Further study of strategies to reduce inappropriate BMA use could lead to less toxicity and lower costs.

Most U.S. medical professionals who treat patients with multiple sclerosis (MS) appear to have adjusted drug regimens during the pandemic’s early months to lower the risk of COVID-19 infection. But they actually didn’t need to make changes then – or now. These are the messages of a pair of new studies that examine the impact of the pandemic on the treatment of MS.

One report finds that 80% of specialists surveyed in the summer of 2020 said the pandemic may have changed how they prescribe disease-modifying therapies (DMTs). However, the other report finds no evidence that choice of DMT affects risk of COVID-19 infection. Both studies were presented at the 2021 Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC).

For the survey, researchers led by neurologist Elizabeth H. Morrison-Banks, MD, of the University of California, Riverside, sent questions to 188 clinicians who serve on regional National Multiple Sclerosis Society Healthcare Provider Councils. A total of 86 people responded: 45 physicians, 18 rehabilitation therapists, 7 psychologists, 8 advanced practice clinicians, 4 social workers, 2 nurses, a pharmacist, and a researcher.

The results, which were published earlier in 2021 in Multiple Sclerosis and Related Disorders, revealed that the survey participants were prescribing certain DMTs more often: beta-interferons (prescribed more by 28.6% of prescribers), natalizumab (23.8%), and glatiramer acetate (21.4%). Those prescribed less included alemtuzumab (64.2% prescribed it less), cladribine (52.4%), and B cell–depleting agents including ocrelizumab and rituximab (50%). Some specialists suspended drugs entirely (21.4% for alemtuzumab, 16.7% for B cell–depleting agents) or extending dosing intervals (38.1% for natalizumab, 11.9% for fingolimod and siponimod).

“We suspect that some of the lower-efficacy therapies were prescribed more often because these therapies were much less immunosuppressive, and because they did not require in-person visits that would increase risk of viral exposure from infusion center staff, or from other infusion patients,” Dr. Morrison-Banks said in an interview. “We also suspect that some of our survey respondents may have increased the dosing intervals for higher-efficacy therapies such as B cell–modulating agents – or even avoided these therapies altogether – because they were concerned that immunosuppressive agents might trigger severe complications from COVID-19.”

As she noted, “in retrospect, at least some of the concerns expressed in our survey may not have been entirely warranted, but then again, we all knew even less then about COVID-19.”

Indeed, researchers led by neurologist Tyler E. Smith, MD, of New York University Langone Multiple Sclerosis Care Center are reporting that they couldn’t find any link between the following DMTs and higher rates of COVID-19 at the New York City center: rituximab, ocrelizumab, fumerate (dimethyl fumarate, monomethyl fumarate, diroximel fumarate), sphingosine-1-phosphate modulators (fingolimod, siponimod), and natalizumab.

The researchers tracked 1,439 patients with MS who were taking the DMTs from March 2020 to March 2021. Of those, 16.0% were infected with COVID-19 (75% lab confirmed), 6.5% were hospitalized, and 0.9% died.

“We did not find an association between the choice of disease-modifying therapy and developing COVID-19 infection, nor having increased disease severity,” Dr. Smith said in an interview. “We are still analyzing data and hope to publish an updated analysis, but at this point, we don’t have conclusive evidence that DMTs, including anti-CD20 agents, need to be changed to lower the risk of COVID-19.”

Instead, he said, “at this point, we feel our energies should be spent on educating our patients on importance of vaccines and boosters. I don’t think it is necessary to switch DMTs because of COVID-19 concerns. However, this should be reviewed on a case-by-case basis.”

No funding is reported for the survey study, and the authors reported various disclosures. The DMT study was funded by an investigator-initiated grant from the Consortium of Multiple Sclerosis Centers, and the authors reported various disclosures.

Morrison-Banks, MD, of the University of California, Riverside, sent questions to 188 clinicians who serve on regional National Multiple Sclerosis Society Healthcare Provider Councils. A total of 86 people responded: 45 physicians, 18 rehabilitation therapists, 7 psychologists, 8 advanced practice clinicians, 4 social workers, 2 nurses, a pharmacist, and a researcher.

The results, which were published earlier in 2021 in Multiple Sclerosis and Related Disorders, revealed that the survey participants were prescribing certain DMTs more often: beta-interferons (prescribed more by 28.6% of prescribers), natalizumab (23.8%), and glatiramer acetate (21.4%). Those prescribed less included alemtuzumab (64.2% prescribed it less), cladribine (52.4%), and B cell–depleting agents including ocrelizumab and rituximab (50%). Some specialists suspended drugs entirely (21.4% for alemtuzumab, 16.7% for B cell–depleting agents) or extending dosing intervals (38.1% for natalizumab, 11.9% for fingolimod and siponimod).

“We suspect that some of the lower-efficacy therapies were prescribed more often because these therapies were much less immunosuppressive, and because they did not require in-person visits that would increase risk of viral exposure from infusion center staff, or from other infusion patients,” Dr. Morrison-Banks said in an interview. “We also suspect that some of our survey respondents may have increased the dosing intervals for higher-efficacy therapies such as B cell–modulating agents – or even avoided these therapies altogether – because they were concerned that immunosuppressive agents might trigger severe complications from COVID-19.”

As she noted, “in retrospect, at least some of the concerns expressed in our survey may not have been entirely warranted, but then again, we all knew even less then about COVID-19.”

Indeed, researchers led by neurologist Tyler E. Smith, MD, of New York University Langone Multiple Sclerosis Care Center are reporting that they couldn’t find any link between the following DMTs and higher rates of COVID-19 at the New York City center: rituximab, ocrelizumab, fumerate (dimethyl fumarate, monomethyl fumarate, diroximel fumarate), sphingosine-1-phosphate modulators (fingolimod, siponimod), and natalizumab.

The researchers tracked 1,439 patients with MS who were taking the DMTs from March 2020 to March 2021. Of those, 16.0% were infected with COVID-19 (75% lab confirmed), 6.5% were hospitalized, and 0.9% died.

“We did not find an association between the choice of disease-modifying therapy and developing COVID-19 infection, nor having increased disease severity,” Dr. Smith said in an interview. “We are still analyzing data and hope to publish an updated analysis, but at this point, we don’t have conclusive evidence that DMTs, including anti-CD20 agents, need to be changed to lower the risk of COVID-19.”

Instead, he said, “at this point, we feel our energies should be spent on educating our patients on importance of vaccines and boosters. I don’t think it is necessary to switch DMTs because of COVID-19 concerns. However, this should be reviewed on a case-by-case basis.”

No funding is reported for the survey study, and the authors reported various disclosures. The DMT study was funded by an investigator-initiated grant from the Consortium of Multiple Sclerosis Centers, and the authors reported various disclosures.
 

Most U.S. medical professionals who treat patients with multiple sclerosis (MS) appear to have adjusted drug regimens during the pandemic’s early months to lower the risk of COVID-19 infection. But they actually didn’t need to make changes then – or now. These are the messages of a pair of new studies that examine the impact of the pandemic on the treatment of MS.

One report finds that 80% of specialists surveyed in the summer of 2020 said the pandemic may have changed how they prescribe disease-modifying therapies (DMTs). However, the other report finds no evidence that choice of DMT affects risk of COVID-19 infection. Both studies were presented at the 2021 Annual Meeting of the Consortium of Multiple Sclerosis Centers (CMSC).

Clinicians should use standardized risk assessments, clinical pathways, and tools to evaluate and communicate with patients who present with chest pain (angina), advises a joint clinical practice guideline released by American Heart Association and American College of Cardiology.

While evaluation of chest pain has been covered in previous guidelines, this is the first comprehensive guideline from the AHA and ACC focused exclusively on the evaluation and diagnosis of chest pain.

“As our imaging technologies have evolved, we needed a contemporary approach to which patients need further testing, and which do not, in addition to what testing is effective,” Martha Gulati, MD, University of Arizona, Phoenix, and chair of the guideline writing group, said in an interview.

“Our hope is that we have provided an evidence-based approach to evaluating patients that will assist all of us who manage, diagnose, and treat patients who experience chest pain,” said Dr. Gulati, who is also president-elect of the American Society for Preventive Cardiology.

The guideline was simultaneously published online Oct. 28, 2021, in Circulation and the Journal of the American College of Cardiology.
 

‘Atypical’ is out, ‘noncardiac’ is in

Each year, chest pain sends more than 6.5 million adults to the ED and more than 4 million to outpatient clinics in the United States.

Yet, among all patients who come to the ED, only 5% will have acute coronary syndrome (ACS). More than half will ultimately have a noncardiac reason for their chest pain, including respiratory, musculoskeletal, gastrointestinal, psychological, or other causes.

The guideline says evaluating the severity and the cause of chest pain is essential and advises using standard risk assessments to determine if a patient is at low, intermediate, or high risk for having a cardiac event.

“I hope clinicians take from our guidelines the understanding that low-risk patients often do not need additional testing. And if we communicate this effectively with our patients – incorporating shared decision-making into our practice – we can reduce ‘overtesting’ in low-risk patients,” Dr. Gulati said in an interview.

The guideline notes that women are unique when presenting with ACS symptoms. While chest pain is the dominant and most common symptom for both men and women, women may be more likely to also have symptoms such as nausea and shortness of breath.

The guideline also encourages using the term “noncardiac” if heart disease is not suspected in a patient with angina and says the term “atypical” is a “misleading” descriptor of chest pain and should not be used.

“Words matter, and we need to move away from describing chest pain as ‘atypical’ because it has resulted in confusion when these words are used,” Dr. Gulati stressed.

“Rather than meaning a different way of presenting, it has taken on a meaning to imply it is not cardiac. It is more useful to talk about the probability of the pain being cardiac vs noncardiac,” Dr. Gulati explained.
 

No one best test for everyone

There is also a focus on evaluation of patients with chest pain who present to the ED. The initial goals of ED physicians should be to identify if there are life-threatening causes and to determine if there is a need for hospital admission or testing, the guideline states.

Thorough screening in the ED may help determine who is at high risk versus intermediate or low risk for a cardiac event. An individual deemed to be at low risk may be referred for additional evaluation in an outpatient setting rather than being admitted to the hospital, the authors wrote.

High-sensitivity cardiac troponins are the “preferred standard” for establishing a biomarker diagnosis of acute myocardial infarction, allowing for more accurate detection and exclusion of myocardial injury, they added.

“While there is no one ‘best test’ for every patient, the guideline emphasizes the tests that may be most appropriate, depending on the individual situation, and which ones won’t provide additional information; therefore, these tests should not be done just for the sake of doing them,” Dr. Gulati said in a news release.

“Appropriate testing is also dependent upon the technology and screening devices that are available at the hospital or healthcare center where the patient is receiving care. All imaging modalities highlighted in the guideline have an important role in the assessment of chest pain to help determine the underlying cause, with the goal of preventing a serious cardiac event,” Dr. Gulati added.

The guideline was prepared on behalf of and approved by the AHA and ACC Joint Committee on Clinical Practice Guidelines.

Five other partnering organizations participated in and approved the guideline: the American Society of Echocardiography, the American College of Chest Physicians, the Society for Academic Emergency Medicine, the Society of Cardiovascular Computed Tomography, and the Society for Cardiovascular Magnetic Resonance.

The writing group included representatives from each of the partnering organizations and experts in the field (cardiac intensivists, cardiac interventionalists, cardiac surgeons, cardiologists, emergency physicians, and epidemiologists), as well as a lay/patient representative.

The research had no commercial funding.

FIRST OF 2 PARTS

Borderline personality disorder (BPD) is marked by an ongoing pattern of mood instability, cognitive distortions, problems with self-image, and impulsive behavior, often resulting in problems in relationships. BPD is associated with serious impairment in psychosocial functioning.¹ Patients with BPD tend to use more mental health services than patients with other personality disorders or those with major depressive disorder (MDD).² However, there has been little consensus on the best treatment(s) for this serious and debilitating disorder, and some clinicians view BPD as difficult to treat.

Current treatments for BPD include psychological and pharmacological interventions. Neuromodulation techniques, such as repetitive transcranial magnetic stimulation, may also positively affect BPD symptomatology. In recent years, there have been some promising findings in the treatment of BPD. In this 2-part article, we focus on current (within the last 5 years) findings from randomized controlled trials (RCTs) of BPD treatments. Here in Part 1, we focus on 6 studies that evaluated biological interventions (Table,^3-8). In Part 2, we will focus on RCTs that investigated psychological interventions.

1. Lisoni J, Miotto P, Barlati S, et al. Change in core symptoms of borderline personality disorder by tDCS: a pilot study. Psychiatry Res. 2020;291:113261. doi: 10.1016/j.psychres.2020.113261

Impulsivity has been described as the core feature of BPD that best explains its behavioral, cognitive, and clinical manifestations. Studies have repeatedly demonstrated the role of the prefrontal cortex in modulating impulsivity. Dysfunction of the dorsolateral prefrontal cortex (DLPFC) has been implicated in BPD. DLPFC transcranial direct current stimulation (tDCS) is a well-tolerated, noninvasive neurostimulation technique that can be used to alter cortical brain activity. Lisoni et al³ examined whether a bilateral right anodal/left cathodal tDCS montage could modulate the psychopathology of BPD.

Continue to: Study design...

• In a double-blind, sham-controlled trial, adults who met DSM-IV-TR criteria for BPD were randomized to 3 weeks (15 sessions) of right anodal/left cathodal DLPFC tCDS (n = 15) or sham tDCS (n = 15). This study included patients with comorbid psychiatric disorders, including substance use disorders. Discontinuation or alteration of existing medications was not allowed.
• The presence, severity, and change over time of BPD core symptoms was assessed at baseline and after 3 weeks using several clinical scales, self-questionnaires, and neuropsychological tests, including the Barratt Impulsiveness Scale-11 (BIS-11), Buss-Perry Aggression Questionnaire (BP-AQ), Difficulties in Emotion Regulation Scale (DERS), Hamilton Depression Rating Scale (HAM-D), Beck Depression Inventory (BDI), Hamilton Anxiety Rating Scale (HAM-A), Irritability-Depression Anxiety Scale (IDA), Visual Analog Scales (VAS), and Iowa Gambling Task.

Outcomes

• Participants in the active tDCS group experienced significant reductions in impulsivity, aggression, and craving as measured by the BIS-11, BP-AQ, and VAS.
• Compared to the sham group, the active tDCS group had greater reductions in HAM-D and BDI scores.
• HAM-A and IDA scores were improved in both groups, although the active tDCS group showed greater reductions in IDA scores compared with the sham group.
• As measured by DERS, active tDCS did not improve affective dysregulation more than sham tDCS.

Conclusions/limitations

• Bilateral tDCS targeting the right DLPFC with anodal stimulation is a safe, well-tolerated technique that may modulate core dimensions of BPD, including impulsivity, aggression, and craving.
• Excitatory anodal stimulation of the right DLFPC coupled with inhibitory cathodal stimulation on the left DLPFC may be an effective montage for targeting impulsivity in patients with BPD.
• Study limitations include a small sample size, use of targeted questionnaires only, inclusion of patients with BPD who also had certain comorbid psychiatric disorders, lack of analysis of the contributions of medications, lack of functional neuroimaging, and lack of a follow-up phase.

2. Molavi P, Aziziaram S, Basharpoor S, et al. Repeated transcranial direct current stimulation of dorsolateral-prefrontal cortex improves executive functions, cognitive reappraisal emotion regulation, and control over emotional processing in borderline personality disorder: a randomized, sham-controlled, parallel-group study. J Affect Disord. 2020;274:93-102. doi: 10.1016/j.jad.2020.05.007

Emotional dysregulation is considered a core feature of BPD psychopathology and is closely associated with executive dysfunction and cognitive control. Manifestations of executive dysfunction include aggressiveness, impulsive decision-making, disinhibition, and self-destructive behaviors. Neuroimaging of patients with BPD has shown enhanced activity in the insula, posterior cingulate cortex, and amygdala, with reduced activity in the medial PFC, subgenual anterior cingulate cortex, and DLPFC. Molavi et al⁴ postulated that increasing DLPFC activation with left anodal tDCS would result in improved executive functioning and emotion dysregulation in patients with BPD.

Study design

• In this single-blind, sham-controlled, parallel-group study, adults who met DSM-5 criteria for BPD were randomized to receive 10 consecutive daily sessions of left anodal/right cathodal DLPFC tDCS (n = 16) or sham tDCS (n = 16).
• The effect of tDCS on executive dysfunction, emotion dysregulation, and emotional processing was measured using the Executive Skills Questionnaire for Adults (ESQ), Emotion Regulation Questionnaire (ERQ), and Emotional Processing Scale (EPS). Measurements occurred at baseline and after 10 sessions of active or sham tDCS.

Outcomes

• Participants who received active tDCS experienced significant improvements in ESQ overall score and most of the executive function domains measured by the ESQ.
• Those in the active tDCS group also experienced significant improvement in emotion regulation as measured by the cognitive reappraisal subscale (but not the expressive suppression subscale) of the ERQ after the intervention.
• Overall emotional processing as measured by the EPS was significantly improved in the active tDCS group following the intervention.

Conclusions/limitations

• Repeated bilateral left anodal/right cathodal tDCS stimulation of the DLPFC significantly improved executive functioning and aspects of emotion regulation and emotional processing in patients with BPD. This improvement was presumed to be the result of increased activity of left DLPFC.
• Study limitations include a single-blind design, lack of follow-up to assess durability and stability of response over time, reliance on self-report measures, lack of functional neuroimaging, and limited focality of tDCS.

3. Crawford MJ, Sanatinia R, Barrett B, et al; LABILE study team. The clinical effectiveness and cost-effectiveness of lamotrigine in borderline personality disorder: a randomized placebo-controlled trial. Am J Psychiatry. 2018;175(8):756-764. doi: 10.1176/appi.ajp.2018.17091006

One of the hallmark symptoms of BPD is mood dysregulation. Current treatment guidelines recommend the use of mood stabilizers for BPD despite limited quality evidence of effectiveness and a lack of FDA-approved medications with this indication. In this RCT, Crawford et al⁵ examined whether lamotrigine is a clinically effective and cost-effective treatment for people with BPD.

Continue to: Study design...

• In this 2-arm, parallel-group, double-blind, placebo-controlled trial, 276 adults who met DSM-IV criteria for BPD were randomized to receive lamotrigine (up to 400 mg/d) or placebo for 52 weeks.
• The primary outcome was the score on the Zanarini Rating Scale for Borderline Personality Disorder (ZAN-BPD) at 52 weeks. Secondary outcomes included depressive symptoms, deliberate self-harm, social functioning, health-related quality of life, resource use and costs, treatment adverse effects, and adverse events. These were assessed using the BDI; Acts of Deliberate Self-Harm Inventory; Social Functioning Questionnaire; Alcohol, Smoking, and Substance Involvement Screening Test; and the EQ-5D-3L.

Outcomes

• Mean ZAN-BPD score decreased at 12 weeks in both groups, after which time the score remained stable.
• There was no difference in ZAN-BPD scores at 52 weeks between treatment arms. No difference was found in any secondary outcome measures.
• Difference in costs between groups was not significant.

Conclusions/limitations

• There was no evidence that lamotrigine led to clinical improvements in BPD symptomatology, social functioning, health-related quality of life, or substance use.
• Lamotrigine is neither clinically effective nor a cost-effective use of resources in the treatment of BPD.
• Limitations include a low level of adherence.

4. Domes G, Ower N, von Dawans B, et al. Effects of intranasal oxytocin administration on empathy and approach motivation in women with borderline personality disorder: a randomized controlled trial. Transl Psychiatry. 2019;9(1):328. doi: 10.1038/s41398-019-0658-4

A core feature of BPD is impairment in empathy; adequate empathy is required for intact social functioning. Oxytocin is a neuropeptide that helps regulate complex social cognition and behavior. Prior research has found that oxytocin administration enhances emotion regulation and empathy. Women with BPD have been observed to have lower levels of oxytocin. Domes et al⁶ conducted an RCT to see if oxytocin could have a beneficial effect on social approach and social cognition in women with BPD.

Study design

• In a double-blind, placebo-controlled, between-subject trial, 61 women who met DSM-IV criteria for BPD and 68 matched healthy controls were randomized to receive intranasal oxytocin, 24 IU, or placebo 45 minutes before completing an empathy task.
• An extended version of the Multifaceted Empathy Test was used to assess empathy and approach motivation.

Outcomes

• For cognitive empathy, patients with BPD exhibited significantly lower overall performance compared to controls. There was no effect of oxytocin on this performance in either group.
• Patients with BPD had significantly lower affective empathy compared with controls. After oxytocin administration, patients with BPD had significantly higher affective empathy than those with BPD who received placebo, reaching the level of healthy controls who received placebo.
• For positive stimuli, patients with BPD showed lower affective empathy than controls. Oxytocin treatment increased affective empathy in both groups.
• For negative stimuli, oxytocin increased affective empathy more in patients with BPD than in controls.
• Patients with BPD demonstrated less approach motivation than controls. Oxytocin increased approach motivation more in patients with BPD than in controls. For approach motivation toward positive stimuli, oxytocin had a significant effect on patients with BPD.

Continue to: Conclusions/limitations...

Conclusions/limitations

• Patients with BPD showed reduced cognitive and affective empathy and less approach behavior motivation than healthy controls.
• Patients with BPD who received oxytocin attained a level of affective empathy and approach motivation similar to that of healthy controls who received placebo. For positive stimuli, both groups exhibited comparable improvements from oxytocin. For negative stimuli, patients with BPD patients showed significant improvement with oxytocin, whereas healthy controls received no such benefit.
• Limitations include the use of self-report scales, lack of a control group, and inclusion of patients using psychotherapeutic medications. The study lacks generalizability because only women were included; the effect of exogenous oxytocin on men may differ.

5. Bozzatello P, Rocca P, Uscinska M, et al. Efficacy and tolerability of asenapine compared with olanzapine in borderline personality disorder: an open-label randomized controlled trial. CNS Drugs. 2017;31(9):809-819. doi: 10.1007/s40263-017-0458-4

The last decade has seen a noticeable shift in clinical practice from the use of antidepressants to mood stabilizers and second-generation antipsychotics (SGAs) in the treatment of BPD. Studies have demonstrated therapeutic effects of antipsychotic drugs across a wide range of BPD symptoms. Among SGAs, olanzapine is the most extensively studied across case reports, open-label studies, and RCTs of patients with BPD. In an RCT, Bozzatello et al⁷ compared the efficacy and tolerability of asenapine to olanzapine.

Study design

• In this open-label RCT, adults who met DSM-5 criteria for BPD were assigned to receive asenapine (n = 25) or olanzapine (n = 26) for 12 weeks.
• Study measurements included the Clinical Global Impression Scale, Severity item, HAM-D, HAM-A, Social and Occupational Functioning Assessment Scale, Borderline Personality Disorder Severity Index (BPDSI), BIS-11, Modified Overt Aggression Scale, and Dosage Record Treatment Emergent Symptom Scale.

Outcomes

• Asenapine and olanzapine had similar effects on BPD-related psychopathology, anxiety, and social and occupational functioning.
• Neither medication significantly decreased depressive or aggressive symptoms.
• Asenapine was superior to olanzapine in reducing the affective instability score of the BPDSI.
• Akathisia and restlessness/anxiety were more common with asenapine, and somnolence and fatigue were more common with olanzapine.

Conclusions/limitations

• The overall efficacy of asenapine was not different from olanzapine, and both medications were well-tolerated.
• Neither medication led to an improvement in depression or aggression, but asenapine was superior to olanzapine in reducing the severity of affective instability.
• Limitations include an open-label design, lack of placebo group, small sample size, high drop-out rate, exclusion of participants with co-occurring MDD and substance abuse/dependence, lack of data on prior pharmacotherapies and psychotherapies, and lack of power to detect a difference on the dissociation/paranoid ideation item of BPDSI.

It has been hypothesized that glutamate dysregulation and excitotoxicity are crucial to the development of the cognitive disturbances that underlie BPD. As such, glutamate modulators such as memantine hold promise for the treatment of BPD. In this RCT, Kulkarni et al⁸ examined the efficacy and tolerability of memantine compared with treatment as usual in patients with BPD.

Continue to: Study design...

• In an 8-week, double-blind, placebo-controlled trial, adults diagnosed with BPD according to the Diagnostic Interview for Borderline Patients were randomized to receive memantine (n = 17) or placebo (n = 16) in addition to treatment as usual. Treatment as usual included the use of antidepressants, mood stabilizers, and antipsychotics as well as psychotherapy and other psychosocial interventions.
• Patients were initiated on placebo or memantine, 10 mg/d. Memantine was increased to 20 mg/d after 7 days.
• ZAN-BPD score was the primary outcome and was measured at baseline and 2, 4, 6, and 8 weeks. An adverse effects questionnaire was administered every 2 weeks to assess tolerability.

Outcomes

• During the first 2 weeks of treatment, there were no significant improvements in ZAN-BPD score in the memantine group compared with the placebo group.
• Beginning with Week 2, compared with the placebo group, the memantine group experienced a significant reduction in total symptoms as measured by ZAN-BPD.
• There were no statistically significant differences in adverse events between groups.

Conclusions/limitations

• Memantine appears to be a well-tolerated treatment option for patients with BPD and merits further study.
• Limitations include a small sample size, and an inability to reach plateau of ZAN-BPD total score in either group. Also, there is considerable individual variability in memantine steady-state plasma concentrations, but plasma levels were not measured in this study.

Bottom Line

Findings from small randomized controlled trials suggest that transcranial direct current stimulation, oxytocin, asenapine, olanzapine, and memantine may have beneficial effects on some core symptoms of borderline personality disorder. These findings need to be replicated in larger studies.

FIRST OF 2 PARTS

Borderline personality disorder (BPD) is marked by an ongoing pattern of mood instability, cognitive distortions, problems with self-image, and impulsive behavior, often resulting in problems in relationships. BPD is associated with serious impairment in psychosocial functioning.¹ Patients with BPD tend to use more mental health services than patients with other personality disorders or those with major depressive disorder (MDD).² However, there has been little consensus on the best treatment(s) for this serious and debilitating disorder, and some clinicians view BPD as difficult to treat.

Current treatments for BPD include psychological and pharmacological interventions. Neuromodulation techniques, such as repetitive transcranial magnetic stimulation, may also positively affect BPD symptomatology. In recent years, there have been some promising findings in the treatment of BPD. In this 2-part article, we focus on current (within the last 5 years) findings from randomized controlled trials (RCTs) of BPD treatments. Here in Part 1, we focus on 6 studies that evaluated biological interventions (Table,^3-8). In Part 2, we will focus on RCTs that investigated psychological interventions.

Impulsivity has been described as the core feature of BPD that best explains its behavioral, cognitive, and clinical manifestations. Studies have repeatedly demonstrated the role of the prefrontal cortex in modulating impulsivity. Dysfunction of the dorsolateral prefrontal cortex (DLPFC) has been implicated in BPD. DLPFC transcranial direct current stimulation (tDCS) is a well-tolerated, noninvasive neurostimulation technique that can be used to alter cortical brain activity. Lisoni et al³ examined whether a bilateral right anodal/left cathodal tDCS montage could modulate the psychopathology of BPD.

Continue to: Study design...

• In a double-blind, sham-controlled trial, adults who met DSM-IV-TR criteria for BPD were randomized to 3 weeks (15 sessions) of right anodal/left cathodal DLPFC tCDS (n = 15) or sham tDCS (n = 15). This study included patients with comorbid psychiatric disorders, including substance use disorders. Discontinuation or alteration of existing medications was not allowed.
• The presence, severity, and change over time of BPD core symptoms was assessed at baseline and after 3 weeks using several clinical scales, self-questionnaires, and neuropsychological tests, including the Barratt Impulsiveness Scale-11 (BIS-11), Buss-Perry Aggression Questionnaire (BP-AQ), Difficulties in Emotion Regulation Scale (DERS), Hamilton Depression Rating Scale (HAM-D), Beck Depression Inventory (BDI), Hamilton Anxiety Rating Scale (HAM-A), Irritability-Depression Anxiety Scale (IDA), Visual Analog Scales (VAS), and Iowa Gambling Task.

Outcomes

• Participants in the active tDCS group experienced significant reductions in impulsivity, aggression, and craving as measured by the BIS-11, BP-AQ, and VAS.
• Compared to the sham group, the active tDCS group had greater reductions in HAM-D and BDI scores.
• HAM-A and IDA scores were improved in both groups, although the active tDCS group showed greater reductions in IDA scores compared with the sham group.
• As measured by DERS, active tDCS did not improve affective dysregulation more than sham tDCS.

Conclusions/limitations

• Bilateral tDCS targeting the right DLPFC with anodal stimulation is a safe, well-tolerated technique that may modulate core dimensions of BPD, including impulsivity, aggression, and craving.
• Excitatory anodal stimulation of the right DLFPC coupled with inhibitory cathodal stimulation on the left DLPFC may be an effective montage for targeting impulsivity in patients with BPD.
• Study limitations include a small sample size, use of targeted questionnaires only, inclusion of patients with BPD who also had certain comorbid psychiatric disorders, lack of analysis of the contributions of medications, lack of functional neuroimaging, and lack of a follow-up phase.

2. Molavi P, Aziziaram S, Basharpoor S, et al. Repeated transcranial direct current stimulation of dorsolateral-prefrontal cortex improves executive functions, cognitive reappraisal emotion regulation, and control over emotional processing in borderline personality disorder: a randomized, sham-controlled, parallel-group study. J Affect Disord. 2020;274:93-102. doi: 10.1016/j.jad.2020.05.007

Emotional dysregulation is considered a core feature of BPD psychopathology and is closely associated with executive dysfunction and cognitive control. Manifestations of executive dysfunction include aggressiveness, impulsive decision-making, disinhibition, and self-destructive behaviors. Neuroimaging of patients with BPD has shown enhanced activity in the insula, posterior cingulate cortex, and amygdala, with reduced activity in the medial PFC, subgenual anterior cingulate cortex, and DLPFC. Molavi et al⁴ postulated that increasing DLPFC activation with left anodal tDCS would result in improved executive functioning and emotion dysregulation in patients with BPD.

Study design

• In this single-blind, sham-controlled, parallel-group study, adults who met DSM-5 criteria for BPD were randomized to receive 10 consecutive daily sessions of left anodal/right cathodal DLPFC tDCS (n = 16) or sham tDCS (n = 16).
• The effect of tDCS on executive dysfunction, emotion dysregulation, and emotional processing was measured using the Executive Skills Questionnaire for Adults (ESQ), Emotion Regulation Questionnaire (ERQ), and Emotional Processing Scale (EPS). Measurements occurred at baseline and after 10 sessions of active or sham tDCS.

Outcomes

• Participants who received active tDCS experienced significant improvements in ESQ overall score and most of the executive function domains measured by the ESQ.
• Those in the active tDCS group also experienced significant improvement in emotion regulation as measured by the cognitive reappraisal subscale (but not the expressive suppression subscale) of the ERQ after the intervention.
• Overall emotional processing as measured by the EPS was significantly improved in the active tDCS group following the intervention.

Conclusions/limitations

• Repeated bilateral left anodal/right cathodal tDCS stimulation of the DLPFC significantly improved executive functioning and aspects of emotion regulation and emotional processing in patients with BPD. This improvement was presumed to be the result of increased activity of left DLPFC.
• Study limitations include a single-blind design, lack of follow-up to assess durability and stability of response over time, reliance on self-report measures, lack of functional neuroimaging, and limited focality of tDCS.

One of the hallmark symptoms of BPD is mood dysregulation. Current treatment guidelines recommend the use of mood stabilizers for BPD despite limited quality evidence of effectiveness and a lack of FDA-approved medications with this indication. In this RCT, Crawford et al⁵ examined whether lamotrigine is a clinically effective and cost-effective treatment for people with BPD.

Continue to: Study design...

• In this 2-arm, parallel-group, double-blind, placebo-controlled trial, 276 adults who met DSM-IV criteria for BPD were randomized to receive lamotrigine (up to 400 mg/d) or placebo for 52 weeks.
• The primary outcome was the score on the Zanarini Rating Scale for Borderline Personality Disorder (ZAN-BPD) at 52 weeks. Secondary outcomes included depressive symptoms, deliberate self-harm, social functioning, health-related quality of life, resource use and costs, treatment adverse effects, and adverse events. These were assessed using the BDI; Acts of Deliberate Self-Harm Inventory; Social Functioning Questionnaire; Alcohol, Smoking, and Substance Involvement Screening Test; and the EQ-5D-3L.

Outcomes

• Mean ZAN-BPD score decreased at 12 weeks in both groups, after which time the score remained stable.
• There was no difference in ZAN-BPD scores at 52 weeks between treatment arms. No difference was found in any secondary outcome measures.
• Difference in costs between groups was not significant.

Conclusions/limitations

• There was no evidence that lamotrigine led to clinical improvements in BPD symptomatology, social functioning, health-related quality of life, or substance use.
• Lamotrigine is neither clinically effective nor a cost-effective use of resources in the treatment of BPD.
• Limitations include a low level of adherence.

4. Domes G, Ower N, von Dawans B, et al. Effects of intranasal oxytocin administration on empathy and approach motivation in women with borderline personality disorder: a randomized controlled trial. Transl Psychiatry. 2019;9(1):328. doi: 10.1038/s41398-019-0658-4

A core feature of BPD is impairment in empathy; adequate empathy is required for intact social functioning. Oxytocin is a neuropeptide that helps regulate complex social cognition and behavior. Prior research has found that oxytocin administration enhances emotion regulation and empathy. Women with BPD have been observed to have lower levels of oxytocin. Domes et al⁶ conducted an RCT to see if oxytocin could have a beneficial effect on social approach and social cognition in women with BPD.

Study design

• In a double-blind, placebo-controlled, between-subject trial, 61 women who met DSM-IV criteria for BPD and 68 matched healthy controls were randomized to receive intranasal oxytocin, 24 IU, or placebo 45 minutes before completing an empathy task.
• An extended version of the Multifaceted Empathy Test was used to assess empathy and approach motivation.

Outcomes

• For cognitive empathy, patients with BPD exhibited significantly lower overall performance compared to controls. There was no effect of oxytocin on this performance in either group.
• Patients with BPD had significantly lower affective empathy compared with controls. After oxytocin administration, patients with BPD had significantly higher affective empathy than those with BPD who received placebo, reaching the level of healthy controls who received placebo.
• For positive stimuli, patients with BPD showed lower affective empathy than controls. Oxytocin treatment increased affective empathy in both groups.
• For negative stimuli, oxytocin increased affective empathy more in patients with BPD than in controls.
• Patients with BPD demonstrated less approach motivation than controls. Oxytocin increased approach motivation more in patients with BPD than in controls. For approach motivation toward positive stimuli, oxytocin had a significant effect on patients with BPD.

Continue to: Conclusions/limitations...

Conclusions/limitations

• Patients with BPD showed reduced cognitive and affective empathy and less approach behavior motivation than healthy controls.
• Patients with BPD who received oxytocin attained a level of affective empathy and approach motivation similar to that of healthy controls who received placebo. For positive stimuli, both groups exhibited comparable improvements from oxytocin. For negative stimuli, patients with BPD patients showed significant improvement with oxytocin, whereas healthy controls received no such benefit.
• Limitations include the use of self-report scales, lack of a control group, and inclusion of patients using psychotherapeutic medications. The study lacks generalizability because only women were included; the effect of exogenous oxytocin on men may differ.

The last decade has seen a noticeable shift in clinical practice from the use of antidepressants to mood stabilizers and second-generation antipsychotics (SGAs) in the treatment of BPD. Studies have demonstrated therapeutic effects of antipsychotic drugs across a wide range of BPD symptoms. Among SGAs, olanzapine is the most extensively studied across case reports, open-label studies, and RCTs of patients with BPD. In an RCT, Bozzatello et al⁷ compared the efficacy and tolerability of asenapine to olanzapine.

Study design

• In this open-label RCT, adults who met DSM-5 criteria for BPD were assigned to receive asenapine (n = 25) or olanzapine (n = 26) for 12 weeks.
• Study measurements included the Clinical Global Impression Scale, Severity item, HAM-D, HAM-A, Social and Occupational Functioning Assessment Scale, Borderline Personality Disorder Severity Index (BPDSI), BIS-11, Modified Overt Aggression Scale, and Dosage Record Treatment Emergent Symptom Scale.

Outcomes

• Asenapine and olanzapine had similar effects on BPD-related psychopathology, anxiety, and social and occupational functioning.
• Neither medication significantly decreased depressive or aggressive symptoms.
• Asenapine was superior to olanzapine in reducing the affective instability score of the BPDSI.

• Patients were initiated on placebo or memantine, 10 mg/d. Memantine was increased to 20 mg/d after 7 days.
• ZAN-BPD score was the primary outcome and was measured at baseline and 2, 4, 6, and 8 weeks. An adverse effects questionnaire was administered every 2 weeks to assess tolerability.

Outcomes

• During the first 2 weeks of treatment, there were no significant improvements in ZAN-BPD score in the memantine group compared with the placebo group.
• Beginning with Week 2, compared with the placebo group, the memantine group experienced a significant reduction in total symptoms as measured by ZAN-BPD.
• There were no statistically significant differences in adverse events between groups.

Conclusions/limitations

• Memantine appears to be a well-tolerated treatment option for patients with BPD and merits further study.
• Limitations include a small sample size, and an inability to reach plateau of ZAN-BPD total score in either group. Also, there is considerable individual variability in memantine steady-state plasma concentrations, but plasma levels were not measured in this study.

Bottom Line

Findings from small randomized controlled trials suggest that transcranial direct current stimulation, oxytocin, asenapine, olanzapine, and memantine may have beneficial effects on some core symptoms of borderline personality disorder. These findings need to be replicated in larger studies.

For centuries, animals, especially dogs, have assisted humans in a variety of ways in their daily lives. Animals that assist people with disabilities fall into 2 broad categories: disability service animals, and emotional support animals (ESAs). Often there is confusion in how these categories differ because of the animal’s role and the laws related to them.

This article describes the differences between disability service animals and ESAs, and outlines the forensic and ethical concerns you should consider before agreeing to write a letter for a patient outlining their need for a disability service animal or ESA. A letter may protect a patient and their service animal or ESA in situations where laws and regulations typically prohibit animals, such as on a flight or when renting an apartment or house. Note that a description of how to conduct the formal patient evaluation before writing a verification letter is beyond the scope of this article.

The differences between disability service animals and ESAs

Purpose and training. Disability service animals, or service animals, are dogs of any breed (and in some cases miniature horses) that are specially trained to perform tasks for an individual with a disability (physical, sensory, psychiatric, intellectual, or other mental disability).^1-3 These tasks must be directly related to the individual’s disability.^1,2 On the other hand, ESAs, which can be any species of animal, provide support and minimize the impact of an individual’s emotional or psychological disability based on their presence alone. Unlike disability service animals, ESAs are not trained to perform a specific task or duty.^2,3

There is no legal requirement for service animals to know specific commands, and professional training is not required—individuals can train the animals themselves.¹ Service animals, mainly dogs, can be trained to perform numerous tasks, including⁴:

• attending to an individual’s mobility and activities of daily living
• guiding an individual who is deaf or hearing impaired
• helping to remind an individual to take their medications
• assisting an individual during and/or after a seizure
• alerting individuals with diabetes in advance of low or high blood sugar episodes
• supporting an individual with autism
• assisting an individual with a psychiatric or mental disability
• applying sensory commands such as lying on the person or resting their head on the individual’s lap to help the individual regain behavioral control.

Service dog verification works via an honor system, which can be problematic, especially in the case of psychiatric service dogs, whose handlers may not have a visible disability (Box 1^1,5).
 

Box 1

Legal protections. Under the Americans with Disabilities Act (ADA), individuals with disabilities can bring their service animals into buildings or facilities where members of the public, program participants, clients, customers, patrons, or invitees are allowed.² This does not include private clubs, religious organizations, or places of worship that are not open to the public.^6,7 ESAs do not qualify as service animals under the ADA and are not given the same legal accommodations as service animals.^1,3 Although ESAs were initially covered by the Air Carrier Access Act, they are no longer allowed in aircraft cabins after the US Department of Transportation revised this Act’s regulations in December 2020. ESAs are covered under the Fair Housing Act. Box 2^1-3,6-15 further discusses these laws and protections.

Evidence. In 1998, Dogs for Good (formerly Dogs for the Disabled), an organization based in the United Kingdom, conducted a survey that assessed the satisfaction of owners who were provided with trained assistance dogs.¹⁶ The results suggested that service dogs improved their owners’ mobility and helped ease the completion of tasks, thereby helping their owners integrate further on a society level and gain a strong bond with their animal.¹⁶ Another survey compared quality of life scores of individuals who owned a service dog vs individuals who were eligible to receive a dog, but did not yet have one.¹⁷ It found that service animals were able to help their owners gain a greater degree of freedom and enhance their ability to participate in everyday outings or tasks that may otherwise have been a struggle, or impossible, if the owner were alone.¹⁷ In addition to boosting confidence, self-esteem, and improving social integration, service dogs have been shown to improve their owners’ quality of life.¹⁷

Due to the difficulty in reconciling inconsistent definitions for ESAs, there is limited high-quality data pertaining to the potential benefits and risks of ESAs.⁹ Currently, ESAs are not an evidence-based treatment for psychiatric disorders. To date, a handful of small studies have focused on ESAs. However, data from actual tests of the clinical risks and benefits of ESAs do not exist.⁹ In practice, ESAs are equivalent to pets. It stands to reason that similar to pets, ESAs could reduce loneliness, improve life satisfaction, and provide a sense of well-being.⁹ A systematic review suggested that pets provide benefits to patients with mental health conditions “through the intensity of connectivity with their owners and the contribution they make to emotional support in times of crises together with their ability to help manage symptoms when they arise.”¹⁸ In response to a congressional mandate, the US Department of Veterans Affairs launched a multi-site study from December 2014 to June 2019 to examine how limitations on activity and quality of life in veterans with posttraumatic stress disorder are impacted by the provision of a service dog vs an emotional support dog.¹⁹ As of October 14, 2021, results had not been published.¹⁹

What’s in a disability service animal/ESA letter?

If you decide to write a letter advocating for your patient to have a service animal or ESA, the letter should appear on letterhead, be written by a licensed mental health professional, and include the following^2,20:

• statement that the letter is being written at the patient’s request and is being given directly to the patient for use as the patient sees fit
• confirmation of the patient’s DSM-5 mental health diagnosis
• explanation of how the animal helps alleviate symptoms of the patient’s condition, briefly describing any interaction(s) between the animal and patient that you may have observed, and if applicable, a mention of any training the animal may have received from a qualified trainer if applicable
• explanation of the possible negative effects of the patient not having the animal with him or her
• statement that you are not vouching for the animal’s behavior
• verification of your involvement in your patient’s treatment and your assessment of the patient as their licensed mental health professional (including details such as date and type of license you have and the state/other jurisdiction where it was issued).

In a letter for a service animal, also indicate that your patient is psychiatrically disabled to the extent that your patient is not able to perform at least one major life task without the daily assistance of a service animal.²Should you write your patient a letter?

Writing a letter advocating for a patient to have a service animal or ESA may appear innocuous, but doing so may have serious ramifications. Writing a letter certifying a dog as a service animal does not make that animal a service animal; the dog must be specifically trained for a task or tasks directly related to that individual’s disability. There are no current standards for conducting evaluations to determine the need a patient has for a service animal or ESA. How to conduct such evaluations is beyond the scope of this article. There are meager opportunities for formal education and training on how to conduct these evaluations.⁹ Online resources may be incomplete or inaccurate, and this information is often produced by lay animal enthusiasts and organizations, which can lead to a biased depiction of these animals.⁹

If you decide to write a letter for your patient, consider the following forensic and ethical concerns.

Remain objective. As an advocate for your patient, you may find it difficult to remain neutral and objective when asked to determine if your patient has a disability, the severity of the disability, the impact of the disability on your patient’s life, and the need for a service animal or ESA. Ensure that your advocacy for your patient does not impair your objectivity; if that is difficult, consider referring your patient to a third party who can conduct an objective evaluation.

Understand the risks. If you make written recommendations for special accommodations in a letter and those recommendations are disputed by an agency, that agency could initiate legal action and you may be called to justify your recommendations in a deposition or open court.^9,21 Before writing the letter, ask yourself, “Can I defend my determination that my patient is disabled by a DSM-5 disorder and that this disability requires the presence of an animal in exception to existing policy?”²¹ Be prepared to state in a legal proceeding that the presence of a service animal or ESA is necessary. If you are unwilling to risk exposure to a legal action, then you should likely refrain from writing the letter. It is a crime to fraudulently certify an animal as a service animal in some jurisdictions, and such conduct could result in disciplinary action by your licensing board.²¹

Conduct a systematic examination. When you write a letter for your patient, you are explicitly declaring your patient has a disability or condition. Comprehensive disability determinations are complex and are best conducted by assessing for objective evidence of psychiatric disorders and impairment through the use of standard, systematic examination methods.²² Unstandardized measures (eg, asking patients open-ended questions and then relying on your clinical judgement and interpretation in arriving at conclusions) are not as effective.²² In addition, consider the possibility that your patient may malinger their symptoms in an effort to obtain a letter supporting a service animal or ESA. Assessing for malingering is essential to making a disability determination, especially if a disability claim is based primarily on self-report.²²

Anticipate pushback. Problems can arise when a patient wants a letter that you cannot or will not provide due to your scope of practice. Consider how you would resolve the situation when you do not believe your patient has a disability that requires the presence of a service animal or ESA—or you believe that your patient no longer needs a service animal or ESA—and the patient disagrees.²¹ Disagreeing with your patient’s assessment could result in a conflict of interest that could damage the therapeutic relationship.²¹

One of the most inspiring speeches ever made is Rev. Martin Luther King’s “I have a dream” about ending discrimination and achieving social justice. Many of the tenets of that classic speech are relevant to psychiatric patients who have been subjected to discrimination and bias instead of the compassion and support that they deserve, as do patients with other medical disorders.

Like Rev. King, we all have dreams, spoken and unspoken. They may be related to our various goals or objectives as individuals, spouses, parents, professionals, friends, or citizens of the world. Here, I will elaborate on my dream as a psychiatric physician, educator, and researcher, with decades of experience treating thousands of patients, many of whom I followed for a long time. I have come to see the world through the eyes and painful journeys of suffering psychiatric patients.

Vision of a better world for our patients

So, here is my dream, comprised of multiple parts that many clinician-readers may have incorporated in their own dreams about psychiatry. I have a dream:

• that the ugly, stubborn stigma of mental illness evaporates and is replaced with empathy and compassion
• that genuine full parity be implemented for all psychiatric patients
• that the public becomes far more educated about their own mental health, and cognizant of psychiatric symptoms in their family members and friends, so they can urge them to promptly seek medical help. The public should be aware that the success rate of treating psychiatric disorders is similar to that of many general medical conditions, such as heart, lung, kidney, and liver diseases
• that psychiatry continues to evolve into a clinical neuroscience, respected and appreciated like its sister neurology, and emphasizing that all mental illnesses are biologically rooted in various brain circuits
• that neuroscience literacy among psychiatrists increases dramatically, while maintaining our biopsychosocial clinical framework

Just as Martin Luther King’s dream resonated loudly for decades and led to salutary legal and societal changes, I hope that what I dream about will eventually become reality. My dream is shared by all my fellow psychiatrists, and it will come true if we unite, lobby continuously, and advocate vigorously for our patients and our noble profession. I am sure we shall overcome our challenges someday.

One of the most inspiring speeches ever made is Rev. Martin Luther King’s “I have a dream” about ending discrimination and achieving social justice. Many of the tenets of that classic speech are relevant to psychiatric patients who have been subjected to discrimination and bias instead of the compassion and support that they deserve, as do patients with other medical disorders.

Like Rev. King, we all have dreams, spoken and unspoken. They may be related to our various goals or objectives as individuals, spouses, parents, professionals, friends, or citizens of the world. Here, I will elaborate on my dream as a psychiatric physician, educator, and researcher, with decades of experience treating thousands of patients, many of whom I followed for a long time. I have come to see the world through the eyes and painful journeys of suffering psychiatric patients.

Vision of a better world for our patients

So, here is my dream, comprised of multiple parts that many clinician-readers may have incorporated in their own dreams about psychiatry. I have a dream:

• that the ugly, stubborn stigma of mental illness evaporates and is replaced with empathy and compassion
• that genuine full parity be implemented for all psychiatric patients
• that the public becomes far more educated about their own mental health, and cognizant of psychiatric symptoms in their family members and friends, so they can urge them to promptly seek medical help. The public should be aware that the success rate of treating psychiatric disorders is similar to that of many general medical conditions, such as heart, lung, kidney, and liver diseases
• that psychiatry continues to evolve into a clinical neuroscience, respected and appreciated like its sister neurology, and emphasizing that all mental illnesses are biologically rooted in various brain circuits
• that neuroscience literacy among psychiatrists increases dramatically, while maintaining our biopsychosocial clinical framework
• that federal funding for research into the causes and treatments of psychiatric disorders increases by an order of magnitude, to help accelerate the discovery of cures for disabling psychiatric disorders, which have a serious personal, societal, and financial toll
• that some of the many fabulously wealthy billionaires in this country (and around the world) adopt psychiatry as their favorite charity, and establish powerful and very well-funded research foundations to explore the brain and solve its mysteries in health and disease

For this Psychiatry Leaders’ Perspectives, Awais Aftab, MD, interviewed Maria A. Oquendo, MD, PhD. Dr. Oquendo is the Ruth Meltzer Professor and Chairman of Psychiatry at University of Pennsylvania and Psychiatrist-in-Chief at the Hospital of the University of Pennsylvania. Until 2016, she was Professor of Psychiatry and Vice Chairman for Education at Columbia University. In 2017, she was elected to the National Academy of Medicine, one of the highest honors in medicine. Dr. Oquendo has used positron emission tomography and magnetic resonance imaging to map brain abnormalities in mood disorders and suicidal behavior. Dr. Oquendo is Past President of the American Psychiatric Association (APA), the International Academy of Suicide Research, and the American College of Neuropsychopharmacology (ACNP). She is President of the American Foundation for Suicide Prevention Board of Directors, Vice President of the College of International Neuropsychopharmacology, and has served on the National Institute of Mental Health’s Advisory Council. A recipient of multiple awards in the US, Europe, and South America, most recently, she received the Virginia Kneeland Award for Distinguished Women in Medicine (Columbia University 2016), the Award for Mood Disorders Research (ACP 2017), the Alexandra Symonds Award (APA 2017), the APA’s Research Award (2018), the Dolores Shockley Award (ACNP 2018), the Alexander Glassman Award (Columbia University 2021), and the Senior Investigator Klerman Award (Depression and Bipolar Support Alliance 2021).

Dr. Aftab: A major focus of your presidential year at APA was on prevention in psychiatry (especially suicide prevention), and working toward prevention through collaboration with colleagues in other medical specialties. What is your perspective on where our field presently stands in this regard?

Dr. Oquendo: There are more and more studies that focus on early childhood or pre-adolescence and the utility of intervening at the first sign of a potential issue. This is quite different from what was the case when I was training. Back then, the idea was that in many cases it was best to wait because kids might “grow out of it.” The implication was that care or intervention were “stigmatizing,” or that it could affect the child’s self-esteem and we wanted to “spare” the child. What we are learning now is that there are advantages of intervening early even if the issues are subtle, potentially preventing development of more serious problems down the line. Still, much work remains to be done. Because so many of the disorders we treat are in fact neurodevelopmental, we desperately need more investigators focused on childhood and adolescent mental health. We also need scientists to identify biomarkers that will permit identification of individuals at risk before the emergence of symptoms. Developing that workforce should be front and center if we are to make a dent in the rising rates of psychiatric disorders.

Dr. Aftab: What do you see as some of the strengths of our profession?


Dr. Oquendo: Our profession’s recognition that the doctor-patient relationship remains a powerful element of healing is one of its greatest strengths. Psychiatry is the only area of medicine in which practitioners are students of the doctor-patient relationship. That provides an unparalleled ability to leverage it for good. Another strength is that many who enter psychiatry are humanists, so as a field, we are collectively engaged in working towards improving conditions for our patients and our community.



Dr. Aftab: Are there ways in which the status quo in psychiatry falls short of the ideal? What are our areas of relative weakness?


Dr. Oquendo: The most challenging issue that plagues psychiatry is not of our making, but we do have to address it. The ongoing lack of parity in the US and the insurance industry’s approach of using carve-outs and other strategies to keep psychiatry reimbursement low has led many, if not most, to practice on a cash basis only. This hurts our patients, but also our reputation among our medical colleagues. We need to use creative solutions and engage in advocacy to bring about change.



Dr. Aftab: What is your perception of the threats that psychiatry faces or is likely to face in the future?

Dr. Oquendo: An ongoing threat relates to the low reimbursement for psychiatric services, which tends to drive clinicians towards cash-based practices. Advocacy at the state and federal level as well as with large employers may be one strategy to remedy this inequity.


Dr. Aftab: What do you envision for the future of psychiatry? What sort of opportunities lie ahead for us?



Dr. Oquendo: The adoption of the advances in psychiatry that permit greater reach, such as the adoption of integrated mental health services, utilization of physician extenders, etc., has been slow in psychiatry, but I think the pace is accelerating. This is important because of an upcoming opportunity: the burgeoning need for our help. With stigma quickly decreasing and the younger generations being open about their needs and prioritization of mental health and wellness, it will be a new era, one in which we can make a huge difference in the health and quality of life of the population.

Mrs. C, age 68, is experiencing worsening paranoid delusions. She believes that because she lied about her income when she was younger, the FBI is tracking her and wants to poison her food and spray dangerous fumes in her house. Her paranoia has made it hard for her to sleep, eat, or feel safe in her home.

Mrs. C’s daughter reports that her mother’s delusions started 3 years ago and have worsened in recent months. Mrs. C has no psychiatric history. Her medical history is signifi­cant for renal transplant in 2015, type 2 diabetes, hyperlipidemia, hypertension, and hypothyroidism. She is currently normotensive. Mrs. C’s home medications include cyclosporine, which is a calcineurin inhibitor, 125 mg twice daily (trough level = 138 mcg/L); mycophenolate mofetil, 500 mg twice daily; cinacalcet, 30 mg 3 times a week; metformin, 500 mg twice daily; amlodipine, 5 mg twice daily; levothyroxine, 112 mcg/d; and atorva­statin, 40 mg at bedtime.

As you review her medications, you wonder if the cyclosporine she began receiving after her kidney transplant could be causing or contributing to her worsening paranoid delusions.

Kidney transplantation has become an ideal treatment for patients with end-stage renal disease. In 2020, 22,817 kidney transplants were performed in the United States.¹ Compared with dialysis, kidney transplant allows patients the chance to return to a satisfactory quality of life.² However, to ensure a successful and long-lasting transplant, patients must be started and maintained on lifelong immunosuppressant agents that have potential adverse effects, including nephrotoxicity and hypertension. Further, immunosuppressant agents—particularly calcineurin inhibitors—are associated with potential adverse effects on mental health. The most commonly documented mental health-related adverse effects include insomnia, anxiety, depression, and confusion.³ In this article, we discuss the risk of severe psychosis associated with the use of calcineurin inhibitors.

Calcineurin inhibitors and psychiatric symptoms

Cyclosporine and tacrolimus are calcineurin inhibitors that are commonly used as immunosuppressant agents after kidney transplantation. They primarily work by specifically and competitively binding to and inhibiting the calcineurin protein to reduce the transcriptional activation of cytokine genes for interleukin-2, tumor necrosis factor-alpha, interleukin-3, interleukin-4, CD40L (CD40 ligand), granulocyte-macrophage colony-stimulating factor, and interferon-gamma.^4,5 The ultimate downstream effect is reduced proliferation of T lymphocytes and thereby an immunosuppressed state that will protect against organ rejection. However, this is not the only downstream effect that can occur from inhibiting calcineurin. Cyclosporine and tacrolimus may modulate the activity of dopamine and N-methyl-D-aspartate (NMDA) via calcineurin.^6-8

An increased effect of dopamine in the mesocortical dopaminergic pathway has long been a suspected cause for psychotic symptoms. A study conducted in rodents suggested that tacrolimus selectively modifies the responsivity and sensitivity of postsynaptic dopamine-2 (D2) and dopamine-3 (D3) receptors.⁹ These receptors are important when discussing psychosis because antipsychotic medications work primarily by blocking dopamine D2, while many also block the D3 receptor. We hypothesize that modifying the responsivity and sensitivity of these 2 receptors could increase the risk of a person developing psychosis. It may also provide insight into how to best treat a psychotic episode.

Tacrolimus has been shown to elicit inhibition of NMDA-induced neurotransmitter release and augmentation of depolarization-induced neurotransmitter release.¹⁰ In theory, this potential inhibition at the NMDA receptors may lead to a compensatory and excessive release of glutamate. Elevated glutamate levels in the brain could lead to psychiatric symptoms, including psychosis. This is supported by the psychosis caused by many NMDA receptor antagonists, such as phencyclidine (PCP) and ketamine. Furthermore, a study examining calcineurin in knockout mice showed that the spectrum of behavioral abnormalities was strikingly similar to those in schizophrenia models.¹¹ These mice displayed impaired working memory, impaired attentional function, social withdrawal, and psychomotor agitation. This further supports the idea that calcineurin inhibition can play a significant role in causing psychiatric symptoms by affecting both dopamine and NMDA receptors.

How to address calcineurin inhibitor–induced psychosis

Here we outline a potential treatment strategy to combat psychosis secondary to calcineurin inhibitors. First, evaluate the patient’s calcineurin inhibitor level (either cyclosporine or tacrolimus). Levels should be drawn as a true trough and doses adjusted if necessary via appropriate consultation with a transplant specialist. Because many of the adverse effects associated with these agents are dose-dependent, we suspect that the risk of psychosis and other mental health–related adverse effects may also follow this trend.

Assuming that the calcineurin inhibitor cannot be stopped, changed to a different agent, or subject to a dose decrease, we recommend initiating an antipsychotic medication to control psychotic symptoms. Given the potential effect of calcineurin inhibitors on dopamine, we suggest trialing a second-generation antipsychotic with relatively high affinity for dopamine D2 receptors, such as risperidone or paliperidone. However, compared with patients with schizophrenia, patients receiving a calcineurin inhibitor may be more likely to develop extrapyramidal symptoms (EPS). Therefore, to avoid potential adverse effects, consider using a lower starting dose or an antipsychotic medication with less dopamine D2 affinity, such as quetiapine, olanzapine, or aripiprazole. Furthermore, because post-transplant patients may be at a higher risk for depression, which may be secondary to medication adverse effects, we suggest avoiding first-generation antipsychotics (FGAs) such as haloperidol because FGAs may worsen depressive symptoms.

We recommend initiating risperidone, 1 mg twice a day, for patients with psychosis secondary to a calcineurin inhibitor. If the patient develops EPS, consider switching to an antipsychotic medication with a less potent dopamine D2 blockade, such as quetiapine, olanzapine, or aripiprazole. We recommend an antipsychotic switch rather than adding benztropine or diphenhydramine to the regimen because many transplant recipients may be older patients, and adding anticholinergic medications can be problematic for this population. However, if the patient is younger or has responded particularly well to risperidone, the benefit of adding an anticholinergic medication may outweigh the risks. This decision should be made on an individual basis and may include other options, such as a switch to quetiapine, olanzapine, or aripiprazole. While these agents may not block the D2 receptor as strongly as risperidone, they all are effective and approved for adjunct therapy in major depressive disorder. We recommend quetiapine and olanzapine as second-line agents because of their potential for sedation and significant weight gain. While aripiprazole has a great metabolic adverse effect profile, its mechanism of action as a partial D2 agonist may make it difficult to control psychotic symptoms in this patient population compared with true D2 antagonists.

Mrs. C is admitted to the inpatient psychiatric unit and started on risperidone, 1 mg twice daily. Initially, she complains of lightheadedness at night due to the risperidone, so her dose is changed to 2 mg at bedtime. Gradually, she begins to show mild improvement. Previously, she reported feeling frightened of staff members, but after a few days she reports that she feels safe at the hospital. However, her delusions of being monitored by the FBI persist.

After 9 days of hospitalization, Mrs. C is discharged home to the care of her daughter. At first, she does well, but unfortunately she begins to refuse to take her medication and returns to her baseline.

Mrs. C, age 68, is experiencing worsening paranoid delusions. She believes that because she lied about her income when she was younger, the FBI is tracking her and wants to poison her food and spray dangerous fumes in her house. Her paranoia has made it hard for her to sleep, eat, or feel safe in her home.

Mrs. C’s daughter reports that her mother’s delusions started 3 years ago and have worsened in recent months. Mrs. C has no psychiatric history. Her medical history is signifi­cant for renal transplant in 2015, type 2 diabetes, hyperlipidemia, hypertension, and hypothyroidism. She is currently normotensive. Mrs. C’s home medications include cyclosporine, which is a calcineurin inhibitor, 125 mg twice daily (trough level = 138 mcg/L); mycophenolate mofetil, 500 mg twice daily; cinacalcet, 30 mg 3 times a week; metformin, 500 mg twice daily; amlodipine, 5 mg twice daily; levothyroxine, 112 mcg/d; and atorva­statin, 40 mg at bedtime.

As you review her medications, you wonder if the cyclosporine she began receiving after her kidney transplant could be causing or contributing to her worsening paranoid delusions.

Kidney transplantation has become an ideal treatment for patients with end-stage renal disease. In 2020, 22,817 kidney transplants were performed in the United States.¹ Compared with dialysis, kidney transplant allows patients the chance to return to a satisfactory quality of life.² However, to ensure a successful and long-lasting transplant, patients must be started and maintained on lifelong immunosuppressant agents that have potential adverse effects, including nephrotoxicity and hypertension. Further, immunosuppressant agents—particularly calcineurin inhibitors—are associated with potential adverse effects on mental health. The most commonly documented mental health-related adverse effects include insomnia, anxiety, depression, and confusion.³ In this article, we discuss the risk of severe psychosis associated with the use of calcineurin inhibitors.

Calcineurin inhibitors and psychiatric symptoms

Cyclosporine and tacrolimus are calcineurin inhibitors that are commonly used as immunosuppressant agents after kidney transplantation. They primarily work by specifically and competitively binding to and inhibiting the calcineurin protein to reduce the transcriptional activation of cytokine genes for interleukin-2, tumor necrosis factor-alpha, interleukin-3, interleukin-4, CD40L (CD40 ligand), granulocyte-macrophage colony-stimulating factor, and interferon-gamma.^4,5 The ultimate downstream effect is reduced proliferation of T lymphocytes and thereby an immunosuppressed state that will protect against organ rejection. However, this is not the only downstream effect that can occur from inhibiting calcineurin. Cyclosporine and tacrolimus may modulate the activity of dopamine and N-methyl-D-aspartate (NMDA) via calcineurin.^6-8

An increased effect of dopamine in the mesocortical dopaminergic pathway has long been a suspected cause for psychotic symptoms. A study conducted in rodents suggested that tacrolimus selectively modifies the responsivity and sensitivity of postsynaptic dopamine-2 (D2) and dopamine-3 (D3) receptors.⁹ These receptors are important when discussing psychosis because antipsychotic medications work primarily by blocking dopamine D2, while many also block the D3 receptor. We hypothesize that modifying the responsivity and sensitivity of these 2 receptors could increase the risk of a person developing psychosis. It may also provide insight into how to best treat a psychotic episode.

Tacrolimus has been shown to elicit inhibition of NMDA-induced neurotransmitter release and augmentation of depolarization-induced neurotransmitter release.¹⁰ In theory, this potential inhibition at the NMDA receptors may lead to a compensatory and excessive release of glutamate. Elevated glutamate levels in the brain could lead to psychiatric symptoms, including psychosis. This is supported by the psychosis caused by many NMDA receptor antagonists, such as phencyclidine (PCP) and ketamine. Furthermore, a study examining calcineurin in knockout mice showed that the spectrum of behavioral abnormalities was strikingly similar to those in schizophrenia models.¹¹ These mice displayed impaired working memory, impaired attentional function, social withdrawal, and psychomotor agitation.

"Effortless.” “Weightless.” “Limitless.” “Carefree.” In most cases, these are words one would not commonly associate with running. In fact, many people might experience an uptick in anxiety when fathoming the idea of going out for a run. Believe it or not, these words are direct quotes from runners describing the feeling of a “runner’s high”—a well-documented organic euphoria that cannot be purchased or abused. But how is the innately basic and monotonous act of running able to reliably transform something as complex as human emotion? This answer lies in the endocannabinoid system.

For decades, scientists and the public believed the runner’s high was associated with an exercise-induced increase in levels of opioid peptides called beta-endorphins. The problem with this theory is that beta-endorphin, released into the blood by the pituitary gland in response to exercise and stress, has difficulty passing through the blood-brain barrier, rendering central effects of this peripheral opioid unlikely.¹ Only recently have researchers been examining the effects of exercise as it pertains to the endocannabinoid system.² Interest in the study of this system is peaking as use of cannabis and hemp-based products reaches an all-time high.

Exploring the endocannabinoid system

Within the last 25 years, the endocannabinoid system has emerged as a highly relevant and unique neuromodulatory system. As with other neurotransmitter systems, the endocannabinoid system is comprised of the endogenous cannabinoids, their receptors, and an array of enzymes responsible for both synthesis and degradation. Endocannabinoid receptors are ubiquitous in the brain and take effect primarily in the cortex, amygdala, basal ganglia, hippocampus, hypothalamus, and cerebellum. One fascinating feature of endocannabinoids is that their precursors lie embedded within lipid membranes. Nearly on demand, endocannabinoids can be rapidly synthesized and released. This grants them almost immediate availability to get into the action at the synapse.²

One study of mice found that those who were exercised experienced improvements in anxiety behaviors and better tolerance to pain. Further, when the exercised mice were treated with endocannabinoid receptor antagonists, they remained anxious and were more sensitive to pain. Endorphin antagonists had no effect on the outcome of these tests.¹ A similar study conducted in humans found improvement in subjective anxiety scores after 45 minutes of moderate-intensity exercise. This study also showed no change with naltrexone administration vs placebo, again supporting the hypothesis that endorphins play little role in this phenomenon. Interestingly, levels of endogenous cannabinoids were elevated following exercise.³ These findings suggest a possible link between activation of the endogenous endocannabinoid system and the anxiolytic properties of exercise.

For good reason, the endocannabinoid system has attracted substantial interest as a focus for a new class of drugs to treat anxiety and stress-related disorders. It remains unknown how we can best harness its many beneficial effects in a safe and effective manner. With that said, activities such as physical exercise, mindfulness meditation, yoga, and other forms of complementary medicine are immediately available and cost-effective methods that have at least preliminary data revealing their multiple health benefits, including improvement in the symptoms of anxiety and activation of endogenous cannabinoids.^1,3-6

As we are all aware, medical training and practice is full of a variety of stresses and demands. Given these demands, finding a balance between mind, body, and spirit can seem like an impossible task. Besides the obvious physical benefits of regular exercise, running can serve to employ the stress-modifying effects of our endogenous cannabinoid system to reduce perceived anxiety and improve wellness. Indeed, at the start of any bout of exercise—especially running—the transition from rest can be startling. Rest assured that there is good news waiting beyond the first few miles. Your reward for patience and perseverance is a beautiful freedom experienced only by those who have earned it. The best part of it all? It is waiting for you right outside your door.
