SSRI tied to improved cognition in comorbid depression, dementia
The results of the 12-week open-label, single-group study are positive, study investigator Michael Cronquist Christensen, MPA, DrPH, a director with the Lundbeck pharmaceutical company, told this news organization before presenting the results in a poster at the 15th Clinical Trials on Alzheimer’s Disease conference.
“The study confirms earlier findings of improvement in both depressive symptoms and cognitive performance with vortioxetine in patients with depression and dementia and adds to this research that these clinical effects also extend to improvement in health-related quality of life and patients’ daily functioning,” Dr. Christensen said.
“It also demonstrates that patients with depression and comorbid dementia can be safely treated with 20 mg vortioxetine – starting dose of 5 mg for the first week and up-titration to 10 mg at day 8,” he added.
However, he reported that Lundbeck doesn’t plan to seek approval from the U.S. Food and Drug Administration for a new indication. Vortioxetine received FDA approval in 2013 to treat MDD, but 3 years later the agency rejected an expansion of its indication to include cognitive dysfunction.
“Vortioxetine is approved for MDD, but the product can be used in patients with MDD who have other diseases, including other mental illnesses,” Dr. Christensen said.
Potential neurotransmission modulator
Vortioxetine is a selective serotonin reuptake inhibitor and serotonin receptor modulator. According to Dr. Christensen, evidence suggests the drug’s receptor targets “have the potential to modulate neurotransmitter systems that are essential for regulation of cognitive function.”
The researchers recruited 83 individuals aged 55-85 with recurrent MDD that had started before the age of 55. All had MDD episodes within the previous 6 months and comorbid dementia for at least 6 months.
Of the participants, 65.9% were female. In addition, 42.7% had Alzheimer’s disease, 26.8% had mixed-type dementia, and the rest had other types of dementia.
The daily oral dose of vortioxetine started at 5 mg for up to week 1 and then was increased to 10 mg. It was then increased to 20 mg or decreased to 5 mg “based on investigator judgment and patient response.” The average daily dose was 12.3 mg.
In regard to the primary outcome, at week 12 (n = 70), scores on the Montgomery-Åsberg Depression Rating Scale (MADRS) fell by a mean of –12.4 (.78, P < .0001), which researchers deemed to be a significant reduction in severe symptoms.
“A significant and clinically meaningful effect was observed from week 1,” the researchers reported.
“As a basis for comparison, we typically see an improvement around 13-14 points during 8 weeks of antidepressant treatment in adults with MDD who do not have dementia,” Dr. Christensen added.
More than a third of patients (35.7%) saw a reduction in MADRS score by more than 50% at week 12, and 17.2% were considered to have reached MDD depression remission, defined as a MADRS score at or under 10.
For secondary outcomes, the total Digit Symbol Substitution test score grew by 0.65 (standardized effect size) by week 12, showing significant improvement (P < .0001). In addition, participants improved on some other cognitive measures, and Dr. Christensen noted that “significant improvement was also observed in the patients’ health-related quality of life and daily functioning.”
A third of patients had drug-related treatment-emergent adverse events.
Vortioxetine is one of the most expensive antidepressants: It has a list price of $444 a month, and no generic version is currently available.
Small trial, open-label design
In a comment, Claire Sexton, DPhil, senior director of scientific programs and outreach at the Alzheimer’s Association, said the study “reflects a valuable aspect of treatment research because of the close connection between depression and dementia. Depression is a known risk factor for dementia, including Alzheimer’s disease, and those who have dementia may experience depression.”
She cautioned, however, that the trial was small and had an open-label design instead of the “gold standard” of a double-blinded trial with a control group.
The study was funded by Lundbeck, where Dr. Christensen is an employee. Another author is a Lundbeck employee, and a third author reported various disclosures. Dr. Sexton reported no disclosures.

A single pediatric CT scan raises brain cancer risk
Children and young adults who are exposed to a single CT scan of the head or neck before age 22 years are at significantly increased risk of developing a brain tumor, particularly glioma, after at least 5 years, according to results of the large EPI-CT study.
“Translation of our risk estimates to the clinical setting indicates that per 10,000 children who received one head CT examination, about one radiation-induced brain cancer is expected during the 5-15 years following the CT examination,” noted lead author Michael Hauptmann, PhD, from the Institute of Biostatistics and Registry Research, Brandenburg Medical School, Neuruppin, Germany, and coauthors.
“Next to the clinical benefit of most CT scans, there is a small risk of cancer from the radiation exposure,” Dr. Hauptmann told this news organization.
“So, CT examinations should only be used when necessary, and if they are used, the lowest achievable dose should be applied,” he said.
The study was published online in The Lancet Oncology.
“This is a thoughtful and well-conducted study by an outstanding multinational team of scientists that adds further weight to the growing body of evidence that has found exposure to CT scanning increases a child’s risk of developing brain cancer,” commented Rebecca Bindman-Smith, MD, from the University of California, San Francisco, who was not involved in the research.
“The results are real, and important,” she told this news organization, adding that “the authors were conservative in their assumptions, and performed a very large number of sensitivity analyses ... to check that the results were robust to a large range of assumptions – and the results changed relatively little.”
“I do not think there is enough awareness [about this risk],” Dr. Hauptmann said. “There is evidence that a nonnegligible number of CTs is unjustified according to guidelines, and there is evidence that doses vary substantially for the same CT between institutions in the same or different countries.”
Indeed, particularly in the United States, “we perform many CT scans in children and even more so in adults that are simply unnecessary,” agreed Dr. Bindman-Smith, who is professor of epidemiology and biostatistics at the University of California, San Francisco. “It is important for patients and providers to understand that nothing we do in medicine is risk free, including CT scanning. If a CT is necessary, the benefit almost certainly outweighs the risk. But if [not], then it should not be obtained. Both patients and providers must make thoroughly considered decisions before asking for or agreeing to a CT.”
She also pointed out that while this study evaluated the risk only for brain cancer, children who undergo head CTs are also at increased risk for leukemia.
Dose/response relationship
The study included 658,752 individuals from nine European countries and 276 hospitals. Each patient had received at least one CT scan between 1977 and 2014 before they turned 22 years of age. Eligibility requirements included their being alive at least 5 years after the first scan and that they had not previously been diagnosed with cancer or benign brain tumor.
The radiation dose absorbed to the brain and 33 other organs and tissues was estimated for each participant using a dose reconstruction model that included historical information on CT machine settings, questionnaire data, and Digital Imaging and Communication in Medicine header metadata. “Mean brain dose per head or neck CT examination increased from 1984 until about 1991, following the introduction of multislice CT scanners at which point thereafter the mean dose decreased and then stabilized around 2010,” note the authors.
During a median follow-up of 5.6 years (starting 5 years after the first scan), 165 brain cancers occurred, including 121 (73%) gliomas, as well as a variety of other morphologic changes.
The mean cumulative brain dose, which lagged by 5 years, was 47.4 mGy overall and 76.0 mGy among people with brain cancer.
“We observed a significant positive association between the cumulative number of head or neck CT examinations and the risk of all brain cancers combined (P < .0001), and of gliomas separately (P = .0002),” the team reports, adding that, for a brain dose of 38 mGy, which was the average dose per head or neck CT in 2012-2014, the relative risk of developing brain cancer was 1.5, compared with not undergoing a CT scan, and the excess absolute risk per 100,000 person-years was 1.1.
These findings “can be used to give the patients and their parents important information on the risks of CT examination to balance against the known benefits,” noted Nobuyuki Hamada, PhD, from the Central Research Institute of Electric Power Industry, Tokyo, and Lydia B. Zablotska, MD, PhD, from the University of California, San Francisco, writing in a linked commentary.
“In recent years, rates of CT use have been steady or declined, and various efforts (for instance, in terms of diagnostic reference levels) have been made to justify and optimize CT examinations. Such continued efforts, along with extended epidemiological investigations, would be needed to minimize the risk of brain cancer after pediatric CT examination,” they add.
Keeping dose to a minimum
The study’s finding of a dose-response relationship underscores the importance of keeping doses to a minimum, Dr. Bindman-Smith commented. “I do not believe we are doing this nearly enough,” she added.
“In the UCSF International CT Dose Registry, where we have collected CT scans from 165 hospitals on many millions of patients, we found that the average brain dose for a head CT in a 1-year-old is 42 mGy but that this dose varies tremendously, where some children receive a dose of 100 mGy.
“So, a second message is that not only should CT scans be justified and used judiciously, but also they should be optimized, meaning using the lowest dose possible. I personally think there should be regulatory oversight to ensure that patients receive the absolutely lowest doses possible,” she added. “My team at UCSF has written quality measures endorsed by the National Quality Forum as a start for setting explicit standards for how CT should be performed in order to ensure the cancer risks are as low as possible.”
The study was funded through the Belgian Cancer Registry; La Ligue contre le Cancer, L’Institut National du Cancer, France; the Ministry of Health, Labour and Welfare of Japan; the German Federal Ministry of Education and Research; Worldwide Cancer Research; the Dutch Cancer Society; the Research Council of Norway; Consejo de Seguridad Nuclear, Generalitat deCatalunya, Spain; the U.S. National Cancer Institute; the U.K. National Institute for Health Research; and Public Health England.

FROM THE LANCET ONCOLOGY
Statins tied to lower ICH risk regardless of bleed location
A new study has provided further reassurance on questions about the risk of intracerebral hemorrhage (ICH) with statins.
The Danish case-control study, which compared statin use in 2,164 case patients with ICH and in 86,255 matched control persons, found that current statin use was associated with a lower risk of having a first ICH and that the risk was further reduced with longer duration of statin use.
The study also showed that statin use was linked to a lower risk of ICH in the more superficial lobar areas of the brain and in the deeper, nonlobar locations. There was no difference in the magnitude of risk reduction between the two locations.
“Although this study is observational, I feel these data are strong, and the results are reassuring. It certainly does not suggest any increased risk of ICH with statins,” senior author David Gaist, PhD, Odense University Hospital, Denmark, said in an interview.
“On the contrary, it indicates a lower risk, which seems to be independent of the location of the bleed.”
The study was published online in Neurology.
The authors note that statins effectively reduce the occurrence of cardiovascular events and ischemic stroke in high-risk populations, but early randomized trials raised concerns of an increased risk of ICH among statin users who have a history of stroke.
Subsequent observational studies, including four meta-analyses, included patients with and those without prior stroke. The results were inconsistent, although most found no increase in bleeding. More recent studies have found a lower risk of ICH among statin users; the risk was inversely associated with the duration and intensity of statin treatment.
However, the researchers point out that few studies have assessed the association between statin use and the location of ICH. Hemorrhages that occur in the lobar region of the brain and those that occur in the nonlobar areas can have different pathophysiologies. Arteriolosclerosis, which is strongly associated with hypertension, is a common histologic finding in patients with ICH, regardless of hemorrhage location, while cerebral amyloid angiopathy (CAA) is associated with lobar but not nonlobar ICH.
The current study was conducted to look more closely at the relationship between statin use and hematoma location as a reflection of differences in the underlying pathophysiologies of lobar versus nonlobar ICH.
The researchers used Danish registries to identify all first-ever cases of spontaneous ICH that occurred between 2009 and 2018 in persons older than 55 years in the Southern Denmark region. Patients with traumatic ICH or ICH related to vascular malformations and tumors were excluded.
These cases were verified through medical records. ICH diagnoses were classified as having a lobar or nonlobar location, and patients were matched for age, sex, and calendar year to general population control persons. The nationwide prescription registry was also analyzed to ascertain use of statins and other medications.
The study included 989 patients with lobar ICH who were matched to 39,500 control persons and 1,175 patients with nonlobar ICH who were matched to 46,755 control persons.
Results showed that current statin use was associated with a 16%-17% relative reduction in ICH risk. There was no difference with respect to ICH location.
For lobar ICH, statin use showed an adjusted odds ratio of 0.83 (95% confidence interval, 0.70-0.98); for nonlobar ICH, the adjusted odds ratio was 0.84 (95% CI, 0.72-0.98).
Longer duration of statin use was associated with a greater reduction in risk of ICH; use for more than 5 years was associated with a relative reduction of ICH of 33%-38%, again with no difference with regard to ICH location.
For lobar ICH, statin use for more than 5 years showed an adjusted odds ratio of 0.67 (95% CI, 0.51-0.87); and for nonlobar ICH, the adjusted odds ratio was 0.62 (95% CI, 0.48-0.80).
“We suspected that statins may have more of an effect in reducing nonlobar ICH, as this type is considered to be more associated with arteriosclerosis, compared with lobar ICH,” Dr. Gaist explained. “But we didn’t find that. We found that taking statins was associated with a similar reduction in risk of both lobar and nonlobar ICH.”
Although amyloid angiopathy can contribute to lobar ICH, arteriosclerosis is still involved in the majority of cases, he noted. He cited a recent population-based U.K. study that showed that while histologically verified CAA was present in 58% of patients with a lobar ICH, most also had evidence of arteriosclerosis, with only 13% having isolated CAA pathology.
“If statins exert their effect on reducing ICH by reducing arteriosclerosis, which is likely, then this observation of arteriosclerosis pathology being prevalent in both lobar and nonlobar ICH locations would explain our results,” Dr. Gaist commented.
“Strengths of our study include the large numbers involved and the fact that the patients are unselected. We tried to find everyone who had had a first ICH in a well-defined region of Denmark, so issues of selection are less of a concern than in some other studies,” he noted.
He also pointed out that all the ICH diagnoses were verified from medical records and that in a substudy, brain scans were evaluated, with investigators masked to clinical data to evaluate the location and characteristics of the hematoma. In addition, data on statin use were collected prospectively from a nationwide prescription registry.
Interaction with antihypertensives, anticoagulants?
Other results from the study suggest a possible interaction between statin use and antihypertensive and anticoagulant drugs.
Data showed that the lower ICH risk was restricted to patients who received statins and antihypertensive drugs concurrently. Conversely, only patients who were not concurrently taking anticoagulants had a lower risk of ICH in association with statin use.
Dr. Gaist suggested that the lack of a reduction in ICH with statins among patients taking anticoagulants could be because the increased risk of ICH with anticoagulants was stronger than the reduced risk with statins.
Regarding the fact that the reduced risk of ICH with statins was only observed among individuals who were also taking antihypertensive medication, Dr. Gaist noted that because hypertension is such an important risk factor for ICH, “it may be that to get the true benefit of statins, patients have to have their hypertension controlled.”
However, an alternative explanation could that the finding is a result of “healthy adherer” bias, in which people who take antihypertensive medication and follow a healthy lifestyle as advised would be more likely to take statins.
“The observational nature of our study does not allow us to determine the extent to which associations are causal,” the authors say.
Dr. Gaist also noted that an important caveat in this study is that they focused on individuals who had had a first ICH.
“This data does not inform us about those who have already had an ICH and are taking statins. But we are planning to look at this in our next study,” he said.
The study was funded by the Novo Nordisk Foundation. Dr. Gaist has received speaker honorarium from Bristol-Myers Squibb and Pfizer unrelated to this work.

A new study has provided further reassurance on questions about the risk of intracerebral hemorrhage (ICH) with statins.
The Danish case-control study, which compared statin use in 2,164 case patients with ICH and in 86,255 matched control persons, found that current statin use was associated with a lower risk of having a first ICH and that the risk was further reduced with longer duration of statin use.
The study also showed that statin use was linked to a lower risk of ICH in the more superficial lobar areas of the brain and in the deeper, nonlobar locations. There was no difference in the magnitude of risk reduction between the two locations.
“Although this study is observational, I feel these data are strong, and the results are reassuring. It certainly does not suggest any increased risk of ICH with statins,” senior author David Gaist, PhD, Odense University Hospital, Denmark, said in an interview.
“On the contrary, it indicates a lower risk, which seems to be independent of the location of the bleed.”
The study was published online in Neurology.
The authors note that statins effectively reduce the occurrence of cardiovascular events and ischemic stroke in high-risk populations, but early randomized trials raised concerns of an increased risk of ICH among statin users who have a history of stroke.
Subsequent observational studies, including four meta-analyses, included patients with and those without prior stroke. The results were inconsistent, although most found no increase in bleeding. More recent studies have found a lower risk of ICH among statin users; the risk was inversely associated with the duration and intensity of statin treatment.
However, the researchers point out that few studies have assessed the association between statin use and the location of ICH. Hemorrhages that occur in the lobar region of the brain and those that occur in the nonlobar areas can have different pathophysiologies.

How your voice could reveal hidden disease
: First during puberty, as the vocal cords thicken and the voice box migrates down the throat. Then a second time as aging causes structural changes that may weaken the voice.
But for some of us, there’s another voice shift, when a disease begins or when our mental health declines.
This is why more doctors are looking into voice as a biomarker – something that tells you that a disease is present.
Vital signs like blood pressure or heart rate “can give a general idea of how sick we are. But they’re not specific to certain diseases,” says Yael Bensoussan, MD, director of the University of South Florida, Tampa’s Health Voice Center and the coprincipal investigator for the National Institutes of Health’s Voice as a Biomarker of Health project.
“We’re learning that there are patterns” in voice changes that can indicate a range of conditions, including diseases of the nervous system and mental illnesses, she says.
Speaking is complicated, involving everything from the lungs and voice box to the mouth and brain. “A breakdown in any of those parts can affect the voice,” says Maria Powell, PhD, an assistant professor of otolaryngology (the study of diseases of the ear and throat) at Vanderbilt University, Nashville, Tenn., who is working on the NIH project.
You or those around you may not notice the changes. But researchers say voice analysis as a standard part of patient care – akin to blood pressure checks or cholesterol tests – could help identify those who need medical attention earlier.
Often, all it takes is a smartphone – “something that’s cheap, off-the-shelf, and that everyone can use,” says Ariana Anderson, PhD, director of the University of California, Los Angeles, Laboratory of Computational Neuropsychology.
“You can provide voice data in your pajamas, on your couch,” says Frank Rudzicz, PhD, a computer scientist for the NIH project. “It doesn’t require very complicated or expensive equipment, and it doesn’t require a lot of expertise to obtain.” Plus, multiple samples can be collected over time, giving a more accurate picture of health than a single snapshot from, say, a cognitive test.
Over the next 4 years, the Voice as a Biomarker team will receive nearly $18 million to gather a massive amount of voice data. The goal is 20,000-30,000 samples, along with health data about each person being studied. The result will be a sprawling database scientists can use to develop algorithms linking health conditions to the way we speak.
For the first 2 years, new data will be collected exclusively via universities and high-volume clinics to control quality and accuracy. Eventually, people will be invited to submit their own voice recordings, creating a crowdsourced dataset. “Google, Alexa, Amazon – they have access to tons of voice data,” says Dr. Bensoussan. “But it’s not usable in a clinical way, because they don’t have the health information.”
Dr. Bensoussan and her colleagues hope to fill that void with advance voice screening apps, which could prove especially valuable in remote communities that lack access to specialists or as a tool for telemedicine. Down the line, wearable devices with voice analysis could alert people with chronic conditions when they need to see a doctor.
“The watch says, ‘I’ve analyzed your breathing and coughing, and today, you’re really not doing well. You should go to the hospital,’ ” says Dr. Bensoussan, envisioning a wearable for patients with COPD. “It could tell people early that things are declining.”
Artificial intelligence may be better than a brain at pinpointing the right disease. For example, slurred speech could indicate Parkinson’s, a stroke, or ALS, among other things.
“We can hold approximately seven pieces of information in our head at one time,” says Dr. Rudzicz. “It’s really hard for us to get a holistic picture using dozens or hundreds of variables at once.” But a computer can consider a whole range of vocal markers at the same time, piecing them together for a more accurate assessment.
“The goal is not to outperform a ... clinician,” says Dr. Bensoussan. Yet the potential is unmistakably there: In a recent study of patients with cancer of the larynx, an automated voice analysis tool more accurately flagged the disease than laryngologists did.
“Algorithms have a larger training base,” says Dr. Anderson, who developed an app called ChatterBaby that analyzes infant cries. “We have a million samples at our disposal to train our algorithms. I don’t know if I’ve heard a million different babies crying in my life.”
So which health conditions show the most promise for voice analysis? The Voice as a Biomarker project will focus on five categories.
Voice disorders (cancers of the larynx, vocal fold paralysis, benign lesions on the larynx)
Obviously, vocal changes are a hallmark of these conditions, which cause things like breathiness or “roughness,” a type of vocal irregularity. Hoarseness that lasts at least 2 weeks is often one of the earliest signs of laryngeal cancer. Yet it can take months – one study found 16 weeks was the average – for patients to see a doctor after noticing the changes. Even then, laryngologists still misdiagnosed some cases of cancer when relying on vocal cues alone.
Now imagine a different scenario: The patient speaks into a smartphone app. An algorithm compares the vocal sample with the voices of laryngeal cancer patients. The app spits out the estimated odds of laryngeal cancer, helping providers decide whether to offer the patient specialist care.
Or consider spasmodic dysphonia, a neurological voice disorder that triggers spasms in the muscles of the voice box, causing a strained or breathy voice. Doctors who lack experience with vocal disorders may miss the condition. This is why diagnosis takes an average of nearly 4.5 years, according to a study in the Journal of Voice, and may include everything from allergy testing to psychiatric evaluation, says Dr. Powell. Artificial intelligence technology trained to recognize the disorder could help eliminate such unnecessary testing.
Neurological and neurodegenerative disorders (Alzheimer’s, Parkinson’s, stroke, ALS)
For Alzheimer’s and Parkinson’s, “one of the first changes that’s notable is voice,” usually appearing before a formal diagnosis, says Anais Rameau, MD, an assistant professor of laryngology at Weill Cornell Medicine, New York, and another member of the NIH project. Parkinson’s may soften the voice or make it sound monotone, while Alzheimer’s disease may change the content of speech, leading to an uptick in “umms” and a preference for pronouns over nouns.
With Parkinson’s, vocal changes can occur decades before movement is affected. If doctors could detect the disease at this stage, before tremor emerged, they might be able to flag patients for early intervention, says Max Little, PhD, project director for the Parkinson’s Voice Initiative. “That is the ‘holy grail’ for finding an eventual cure.”
Again, the smartphone shows potential. In a 2022 Australian study, an AI-powered app was able to identify people with Parkinson’s based on brief voice recordings, although the sample size was small. On a larger scale, the Parkinson’s Voice Initiative collected some 17,000 samples from people across the world. “The aim was to remotely detect those with the condition using a telephone call,” says Dr. Little. It did so with about 65% accuracy. “While this is not accurate enough for clinical use, it shows the potential of the idea,” he says.
Dr. Rudzicz worked on the team behind Winterlight, an iPad app that analyzes 550 features of speech to detect dementia and Alzheimer’s (as well as mental illness). “We deployed it in long-term care facilities,” he says, identifying patients who need further review of their mental skills. Stroke is another area of interest, because slurred speech is a highly subjective measure, says Dr. Anderson. AI technology could provide a more objective evaluation.
Mood and psychiatric disorders (depression, schizophrenia, bipolar disorders)
No established biomarkers exist for diagnosing depression. Yet if you’re feeling down, there’s a good chance your friends can tell – even over the phone.
“We carry a lot of our mood in our voice,” says Dr. Powell. Bipolar disorder can also alter voice, making it louder and faster during manic periods, then slower and quieter during depressive bouts. The catatonic stage of schizophrenia often comes with “a very monotone, robotic voice,” says Dr. Anderson. “These are all something an algorithm can measure.”
Apps are already being used – often in research settings – to monitor voices during phone calls, analyzing rate, rhythm, volume, and pitch, to predict mood changes. For example, the PRIORI project at the University of Michigan is working on a smartphone app to identify mood changes in people with bipolar disorder, especially shifts that could increase suicide risk.
The content of speech may also offer clues. In a University of California, Los Angeles, study published in the journal PLoS One, people with mental illnesses answered computer-programmed questions (like “How have you been over the past few days?”) over the phone. An app analyzed their word choices, paying attention to how they changed over time. The researchers found that AI analysis of mood aligned well with doctors’ assessments and that some people in the study actually felt more comfortable talking to a computer.
Respiratory disorders (pneumonia, COPD)
Beyond talking, respiratory sounds like gasping or coughing may point to specific conditions. “Emphysema cough is different, COPD cough is different,” says Dr. Bensoussan. Researchers are trying to find out if COVID-19 has a distinct cough.
Breathing sounds can also serve as signposts. “There are different sounds when we can’t breathe,” says Dr. Bensoussan. One is called stridor, a high-pitched wheezing often resulting from a blocked airway. “I see tons of people [with stridor] misdiagnosed for years – they’ve been told they have asthma, but they don’t,” says Dr. Bensoussan. AI analysis of these sounds could help doctors more quickly identify respiratory disorders.
Pediatric voice and speech disorders (speech and language delays, autism)
Babies who later have autism cry differently as early as 6 months of age, which means an app like ChatterBaby could help flag children for early intervention, says Dr. Anderson. Autism is linked to several other diagnoses, such as epilepsy and sleep disorders. So analyzing an infant’s cry could prompt pediatricians to screen for a range of conditions.
ChatterBaby has been “incredibly accurate” in identifying when babies are in pain, says Dr. Anderson, because pain increases muscle tension, resulting in a louder, more energetic cry. The next goal: “We’re collecting voices from babies around the world,” she says, and then tracking those children for 7 years, looking to see if early vocal signs could predict developmental disorders. Vocal samples from young children could serve a similar purpose.
And that’s only the beginning
Eventually, AI technology may pick up disease-related voice changes that we can’t even hear. In a new Mayo Clinic study, certain vocal features detectable by AI – but not by the human ear – were linked to a three-fold increase in the likelihood of having plaque buildup in the arteries.
“Voice is a huge spectrum of vibrations,” explains study author Amir Lerman, MD. “We hear a very narrow range.”
The researchers aren’t sure why heart disease alters voice, but the autonomic nervous system may play a role, because it regulates the voice box as well as blood pressure and heart rate. Dr. Lerman says other conditions, like diseases of the nerves and gut, may similarly alter the voice. Beyond patient screening, this discovery could help doctors adjust medication doses remotely, in line with these inaudible vocal signals.
“Hopefully, in the next few years, this is going to come to practice,” says Dr. Lerman.
Still, in the face of that hope, privacy concerns remain. Voice is an identifier that’s protected by the federal Health Insurance Portability and Accountability Act, which requires privacy of personal health information. That is a major reason why no large voice databases exist yet, says Dr. Bensoussan. (This makes collecting samples from children especially challenging.) Perhaps more concerning is the potential for diagnosing disease based on voice alone. “You could use that tool on anyone, including officials like the president,” says Dr. Rameau.
But the primary hurdle is the ethical sourcing of data to ensure a diversity of vocal samples. For the Voice as a Biomarker project, the researchers will establish voice quotas for different races and ethnicities, ensuring algorithms can accurately analyze a range of accents. Data from people with speech impediments will also be gathered.
Despite these challenges, researchers are optimistic. “Vocal analysis is going to be a great equalizer and improve health outcomes,” predicts Dr. Anderson. “I’m really happy that we are beginning to understand the strength of the voice.”

“The watch says, ‘I’ve analyzed your breathing and coughing, and today, you’re really not doing well. You should go to the hospital,’ ” says Dr. Bensoussan, envisioning a wearable for patients with COPD. “It could tell people early that things are declining.”
Artificial intelligence may be better than a brain at pinpointing the right disease. For example, slurred speech could indicate Parkinson’s, a stroke, or ALS, among other things.
“We can hold approximately seven pieces of information in our head at one time,” says Dr. Rudzicz. “It’s really hard for us to get a holistic picture using dozens or hundreds of variables at once.” But a computer can consider a whole range of vocal markers at the same time, piecing them together for a more accurate assessment.
“The goal is not to outperform a ... clinician,” says Dr. Bensoussan. Yet the potential is unmistakably there: In a recent study of patients with cancer of the larynx, an automated voice analysis tool more accurately flagged the disease than laryngologists did.
“Algorithms have a larger training base,” says Dr. Anderson, who developed an app called ChatterBaby that analyzes infant cries. “We have a million samples at our disposal to train our algorithms. I don’t know if I’ve heard a million different babies crying in my life.”
So which health conditions show the most promise for voice analysis? The Voice as a Biomarker project will focus on five categories.
Voice disorders (cancers of the larynx, vocal fold paralysis, benign lesions on the larynx)
Obviously, vocal changes are a hallmark of these conditions, which cause things like breathiness or “roughness,” a type of vocal irregularity. Hoarseness that lasts at least 2 weeks is often one of the earliest signs of laryngeal cancer. Yet it can take months – one study found 16 weeks was the average – for patients to see a doctor after noticing the changes. Even then, laryngologists still misdiagnosed some cases of cancer when relying on vocal cues alone.
Now imagine a different scenario: The patient speaks into a smartphone app. An algorithm compares the vocal sample with the voices of laryngeal cancer patients. The app spits out the estimated odds of laryngeal cancer, helping providers decide whether to offer the patient specialist care.
Or consider spasmodic dysphonia, a neurological voice disorder that triggers spasms in the muscles of the voice box, causing a strained or breathy voice. Doctors who lack experience with vocal disorders may miss the condition. This is why diagnosis takes an average of nearly 4.5 years, according to a study in the Journal of Voice, and may include everything from allergy testing to psychiatric evaluation, says Dr. Powell. Artificial intelligence technology trained to recognize the disorder could help eliminate such unnecessary testing.
Neurological and neurodegenerative disorders (Alzheimer’s, Parkinson’s, stroke, ALS)
For Alzheimer’s and Parkinson’s, “one of the first changes that’s notable is voice,” usually appearing before a formal diagnosis, says Anais Rameau, MD, an assistant professor of laryngology at Weill Cornell Medicine, New York, and another member of the NIH project. Parkinson’s may soften the voice or make it sound monotone, while Alzheimer’s disease may change the content of speech, leading to an uptick in “umms” and a preference for pronouns over nouns.
With Parkinson’s, vocal changes can occur decades before movement is affected. If doctors could detect the disease at this stage, before tremor emerged, they might be able to flag patients for early intervention, says Max Little, PhD, project director for the Parkinson’s Voice Initiative. “That is the ‘holy grail’ for finding an eventual cure.”
Again, the smartphone shows potential. In a 2022 Australian study, an AI-powered app was able to identify people with Parkinson’s based on brief voice recordings, although the sample size was small. On a larger scale, the Parkinson’s Voice Initiative collected some 17,000 samples from people across the world. “The aim was to remotely detect those with the condition using a telephone call,” says Dr. Little. It did so with about 65% accuracy. “While this is not accurate enough for clinical use, it shows the potential of the idea,” he says.
Dr. Rudzicz worked on the team behind Winterlight, an iPad app that analyzes 550 features of speech to detect dementia and Alzheimer’s (as well as mental illness). “We deployed it in long-term care facilities,” he says, identifying patients who need further review of their mental skills. Stroke is another area of interest, because slurred speech is a highly subjective measure, says Dr. Anderson. AI technology could provide a more objective evaluation.
Mood and psychiatric disorders (depression, schizophrenia, bipolar disorders)
No established biomarkers exist for diagnosing depression. Yet if you’re feeling down, there’s a good chance your friends can tell – even over the phone.
“We carry a lot of our mood in our voice,” says Dr. Powell. Bipolar disorder can also alter voice, making it louder and faster during manic periods, then slower and quieter during depressive bouts. The catatonic stage of schizophrenia often comes with “a very monotone, robotic voice,” says Dr. Anderson. “These are all something an algorithm can measure.”
Apps are already being used – often in research settings – to monitor voices during phone calls, analyzing rate, rhythm, volume, and pitch, to predict mood changes. For example, the PRIORI project at the University of Michigan is working on a smartphone app to identify mood changes in people with bipolar disorder, especially shifts that could increase suicide risk.
The content of speech may also offer clues. In a University of California, Los Angeles, study published in the journal PLoS One, people with mental illnesses answered computer-programmed questions (like “How have you been over the past few days?”) over the phone. An app analyzed their word choices, paying attention to how they changed over time. The researchers found that AI analysis of mood aligned well with doctors’ assessments and that some people in the study actually felt more comfortable talking to a computer.
Respiratory disorders (pneumonia, COPD)
Beyond talking, respiratory sounds like gasping or coughing may point to specific conditions. “Emphysema cough is different, COPD cough is different,” says Dr. Bensoussan. Researchers are trying to find out if COVID-19 has a distinct cough.
Breathing sounds can also serve as signposts. “There are different sounds when we can’t breathe,” says Dr. Bensoussan. One is called stridor, a high-pitched wheezing often resulting from a blocked airway. “I see tons of people [with stridor] misdiagnosed for years – they’ve been told they have asthma, but they don’t,” says Dr. Bensoussan. AI analysis of these sounds could help doctors more quickly identify respiratory disorders.
Pediatric voice and speech disorders (speech and language delays, autism)
Babies who later have autism cry differently as early as 6 months of age, which means an app like ChatterBaby could help flag children for early intervention, says Dr. Anderson. Autism is linked to several other diagnoses, such as epilepsy and sleep disorders. So analyzing an infant’s cry could prompt pediatricians to screen for a range of conditions.
ChatterBaby has been “incredibly accurate” in identifying when babies are in pain, says Dr. Anderson, because pain increases muscle tension, resulting in a louder, more energetic cry. The next goal: “We’re collecting voices from babies around the world,” she says, and then tracking those children for 7 years, looking to see if early vocal signs could predict developmental disorders. Vocal samples from young children could serve a similar purpose.
And that’s only the beginning
Eventually, AI technology may pick up disease-related voice changes that we can’t even hear. In a new Mayo Clinic study, certain vocal features detectable by AI – but not by the human ear – were linked to a three-fold increase in the likelihood of having plaque buildup in the arteries.
“Voice is a huge spectrum of vibrations,” explains study author Amir Lerman, MD. “We hear a very narrow range.”
The researchers aren’t sure why heart disease alters voice, but the autonomic nervous system may play a role, because it regulates the voice box as well as blood pressure and heart rate. Dr. Lerman says other conditions, like diseases of the nerves and gut, may similarly alter the voice. Beyond patient screening, this discovery could help doctors adjust medication doses remotely, in line with these inaudible vocal signals.
“Hopefully, in the next few years, this is going to come to practice,” says Dr. Lerman.
Still, in the face of that hope, privacy concerns remain. Voice is an identifier that’s protected by the federal Health Insurance Portability and Accountability Act, which requires privacy of personal health information. That is a major reason why no large voice databases exist yet, says Dr. Bensoussan. (This makes collecting samples from children especially challenging.) Perhaps more concerning is the potential for diagnosing disease based on voice alone. “You could use that tool on anyone, including officials like the president,” says Dr. Rameau.
But the primary hurdle is the ethical sourcing of data to ensure a diversity of vocal samples. For the Voice as a Biomarker project, the researchers will establish voice quotas for different races and ethnicities, ensuring algorithms can accurately analyze a range of accents. Data from people with speech impediments will also be gathered.
Despite these challenges, researchers are optimistic. “Vocal analysis is going to be a great equalizer and improve health outcomes,” predicts Dr. Anderson. “I’m really happy that we are beginning to understand the strength of the voice.”

: First during puberty, as the vocal cords thicken and the voice box migrates down the throat. Then a second time as aging causes structural changes that may weaken the voice.
But for some of us, there’s another voice shift, when a disease begins or when our mental health declines.
This is why more doctors are looking into voice as a biomarker – something that tells you that a disease is present.
Vital signs like blood pressure or heart rate “can give a general idea of how sick we are. But they’re not specific to certain diseases,” says Yael Bensoussan, MD, director of the University of South Florida, Tampa’s Health Voice Center and the coprincipal investigator for the National Institutes of Health’s Voice as a Biomarker of Health project.
“We’re learning that there are patterns” in voice changes that can indicate a range of conditions, including diseases of the nervous system and mental illnesses, she says.
Speaking is complicated, involving everything from the lungs and voice box to the mouth and brain. “A breakdown in any of those parts can affect the voice,” says Maria Powell, PhD, an assistant professor of otolaryngology (the study of diseases of the ear and throat) at Vanderbilt University, Nashville, Tenn., who is working on the NIH project.
You or those around you may not notice the changes. But researchers say voice analysis as a standard part of patient care – akin to blood pressure checks or cholesterol tests – could help identify those who need medical attention earlier.
Often, all it takes is a smartphone – “something that’s cheap, off-the-shelf, and that everyone can use,” says Ariana Anderson, PhD, director of the University of California, Los Angeles, Laboratory of Computational Neuropsychology.
“You can provide voice data in your pajamas, on your couch,” says Frank Rudzicz, PhD, a computer scientist for the NIH project. “It doesn’t require very complicated or expensive equipment, and it doesn’t require a lot of expertise to obtain.” Plus, multiple samples can be collected over time, giving a more accurate picture of health than a single snapshot from, say, a cognitive test.
Over the next 4 years, the Voice as a Biomarker team will receive nearly $18 million to gather a massive amount of voice data. The goal is 20,000-30,000 samples, along with health data about each person being studied. The result will be a sprawling database scientists can use to develop algorithms linking health conditions to the way we speak.
For the first 2 years, new data will be collected exclusively via universities and high-volume clinics to control quality and accuracy. Eventually, people will be invited to submit their own voice recordings, creating a crowdsourced dataset. “Google, Alexa, Amazon – they have access to tons of voice data,” says Dr. Bensoussan. “But it’s not usable in a clinical way, because they don’t have the health information.”
Dr. Bensoussan and her colleagues hope to fill that void with advance voice screening apps, which could prove especially valuable in remote communities that lack access to specialists or as a tool for telemedicine. Down the line, wearable devices with voice analysis could alert people with chronic conditions when they need to see a doctor.

No, you can’t see a different doctor: We need zero tolerance of patient bias
It was 1970. I was in my second year of medical school. I can remember the hurt and embarrassment as if it were yesterday.
Coming from the Deep South, I was very familiar with racial bias, but I did not expect it at that level and in that environment. From that point on, I was anxious at each patient encounter, concerned that this might happen again. And it did several times during my residency and fellowship.
The Occupational Safety and Health Administration defines workplace violence as “any act or threat of physical violence, harassment, intimidation, or other threatening disruptive behavior that occurs at the work site. It ranges from threats and verbal abuse to physical assaults.”
There is considerable media focus on incidents of physical violence against health care workers, but when patients, their families, or visitors openly display bias and request a different doctor, nurse, or technician for nonmedical reasons, the impact is profound. This is extremely hurtful to a professional who has worked long and hard to acquire skills and expertise. And, while speech may not constitute violence in the strictest sense of the word, there is growing evidence that it can be physically harmful through its effect on the nervous system, even if no physical contact is involved.
Incidents of bias occur regularly and are clearly on the rise. In most cases the request for a different health care worker is granted to honor the rights of the patient. The healthcare worker is left alone and emotionally wounded; the healthcare institutions are complicit.
This bias is mostly racial but can also be based on religion, sexual orientation, age, disability, body size, accent, or gender.
An entire issue of the American Medical Association Journal of Ethics was devoted to this topic. From recognizing that there are limits to what clinicians should be expected to tolerate when patients’ preferences express unjust bias, the issue also explored where those limits should be placed, why, and who is obliged to enforce them.
The newly adopted Mass General Patient Code of Conduct is evidence that health care systems are beginning to recognize this problem and that such behavior will not be tolerated.
But having a zero-tolerance policy is not enough. We must have procedures in place to discourage and mitigate the impact of patient bias.
A clear definition of what constitutes a bias incident is essential. All team members must be made aware of the procedures for reporting such incidents and the chain of command for escalation. Reporting should be encouraged, and resources must be made available to impacted team members. Surveillance, monitoring, and review are also essential as is clarification on when patient preferences should be honored.
The Mayo Clinic 5 Step Plan is an excellent example of a protocol to deal with patient bias against health care workers and is based on a thoughtful analysis of what constitutes an unreasonable request for a different clinician. I’m pleased to report that my health care system (Inova Health) is developing a similar protocol.
The health care setting should be a bias-free zone for both patients and health care workers. I have been a strong advocate of patients’ rights and worked hard to guard against bias and eliminate disparities in care, but health care workers have rights as well.
We should expect to be treated with respect.

More evidence in utero exposure to antiseizure meds safe for children’s cognition
NASHVILLE, TENN. – There is no negative impact of in utero exposure to antiseizure medications on children’s creativity, new research shows.
The results of this study, along with other research, suggest the risk for cognitive problems “is fairly low” overall for children of women with epilepsy taking lamotrigine or levetiracetam, study investigator, Kimford J. Meador, MD, professor, department of neurology & neurological sciences, Stanford (Calif.) University School of Medicine, told this news organization.
“This is another encouraging piece that’s showing these new drugs are safe with regard to cognition.”
The findings were presented at the annual meeting of the American Epilepsy Society.
Capturing creativity
Fetal exposure to antiseizure medications can produce adverse neurodevelopmental effects. These are typically assessed using measures such as general intelligence, verbal/nonverbal abilities, or additional educational needs.
However, these measures don’t capture creativity, which “is related to intelligence but not completely,” said Dr. Meador. “I have seen wonderful examples of creativity in people who have a lot of cognitive impairment.”
He referred to one of his patients with epilepsy who is “spectacularly good” at painting with watercolors, even though she has significant cognitive impairment.
The new analysis is part of the MONEAD study, a prospective, observational multicenter study examining pregnancy outcomes for both mother and child. It included pregnant women who were enrolled at under 20 weeks’ gestational age.
The women with epilepsy in the study were primarily on monotherapy (73%), and of these, 82% were on lamotrigine or levetiracetam. About 22% were on polytherapy, of which 42% were on dual therapy with lamotrigine and levetiracetam.
Fluency, originality
Researchers assessed the children of these women at age 4½ years using the Torrance Test of Creative Thinking-Figural (TTCT-F). This is a standardized assessment of creative thinking with index scores measuring such things as fluency, originality, abstractness, and elaboration.
Dr. Meador noted the research team used a shorter version of the test battery “so as to not wear out the families and kids.”
During the test, children were given lines of different shapes and asked to draw a picture using these lines. Dr. Meador pointed out the drawings ranged from quite basic to more intricate.
One child cleverly turned a few squiggly lines into a car. “I can look at this and say this kid’s going to do very well,” said Dr. Meador.
Investigators compared scores between 241 children of women with epilepsy (WWE) and 65 children of healthy women (HW). They adjusted for the mother’s IQ, education level, age at enrollment, gestation age at enrollment, post-birth average anxiety score, and the child’s ethnicity and sex.
Investigators found the mean TTCT-F scores did not differ significantly between the two groups: adjusted least squares mean of 89.5 (95% confidence interval, 86.7-92.3) for children of WWE, compared with adjusted least square mean of 92.0 (95% CI, 86.4-97.6) for children of HW.
Balancing act
The researchers haven’t looked at a dose effect in this current study, but Dr. Meador said it’s always “a balancing act” between giving enough of the drug to keep mothers from seizing, which affect both the mother and fetus, and giving as low a dose as possible to protect the fetus.
In addition, as medication levels change during pregnancy, he said he recommends that drug levels are monitored monthly so that medication can be adjusted as necessary.
Looking at what factors might predict creativity scores, researchers found children did less well creatively if their mother didn’t have a college degree (estimate –9.5; 95% CI, –17.9 to –1.2; P = .025).
“It looks like being in a home where the mother has had more education is going to have an impact on the kid’s thinking and creativity,” said Dr. Meador.
These new findings are consistent with a lack of differences in other cognitive abilities that Dr. Meador and his team found when the children were younger.
“At age 3, we did not find an overall difference in cognitive and verbal abilities and intelligence between the children of mothers with epilepsy and those of healthy women,” he said.
The researchers aim to assess cognitive and behavioral outcomes in these children when they are 6 years old.
Helpful information
Commenting on the findings, Stéphane Auvin, MD, PhD, chair of the department of pediatric neurology at the University of Paris, who co-moderated a platform session featuring the research, said the study “is an interesting measure of the impact of being exposed to antiseizure medications.”
Creativity is “complex,” he said. “It’s not only cognition; it could be things like behavior and impulsivity.”
The new information is “very helpful.” Focusing on something broader than just IQ “gives you a better picture of what’s going on.”
The study received funding from NIH, NINDS, and NICH. Dr. Meador has received grants from NIH/NINDS, NIH/NICHD, Veterans Administration, and Eisai. He has been a consultant for Epilepsy Consortium, Novartis, Supernus, Upsher Smith Labs, and UCB Pharma. Dr. Auvin reports no relevant financial relationships.

NASHVILLE, TENN. – There is no negative impact of in utero exposure to antiseizure medications on children’s creativity, new research shows.
The results of this study, along with other research, suggest the risk for cognitive problems “is fairly low” overall for children of women with epilepsy taking lamotrigine or levetiracetam, study investigator, Kimford J. Meador, MD, professor, department of neurology & neurological sciences, Stanford (Calif.) University School of Medicine, told this news organization.
“This is another encouraging piece that’s showing these new drugs are safe with regard to cognition.”
The findings were presented at the annual meeting of the American Epilepsy Society.
Capturing creativity
Fetal exposure to antiseizure medications can produce adverse neurodevelopmental effects. These are typically assessed using measures such as general intelligence, verbal/nonverbal abilities, or additional educational needs.
However, these measures don’t capture creativity, which “is related to intelligence but not completely,” said Dr. Meador. “I have seen wonderful examples of creativity in people who have a lot of cognitive impairment.”
He referred to one of his patients with epilepsy who is “spectacularly good” at painting with watercolors, even though she has significant cognitive impairment.
The new analysis is part of the MONEAD study, a prospective, observational multicenter study examining pregnancy outcomes for both mother and child. It included pregnant women who were enrolled at under 20 weeks’ gestational age.
The women with epilepsy in the study were primarily on monotherapy (73%), and of these, 82% were on lamotrigine or levetiracetam. About 22% were on polytherapy, of which 42% were on dual therapy with lamotrigine and levetiracetam.
Fluency, originality
Researchers assessed the children of these women at age 4½ years using the Torrance Test of Creative Thinking-Figural (TTCT-F). This is a standardized assessment of creative thinking with index scores measuring such things as fluency, originality, abstractness, and elaboration.
Dr. Meador noted the research team used a shorter version of the test battery “so as to not wear out the families and kids.”
During the test, children were given lines of different shapes and asked to draw a picture using these lines. Dr. Meador pointed out the drawings ranged from quite basic to more intricate.
One child cleverly turned a few squiggly lines into a car. “I can look at this and say this kid’s going to do very well,” said Dr. Meador.
Investigators compared scores between 241 children of women with epilepsy (WWE) and 65 children of healthy women (HW). They adjusted for the mother’s IQ, education level, age at enrollment, gestation age at enrollment, post-birth average anxiety score, and the child’s ethnicity and sex.
Investigators found the mean TTCT-F scores did not differ significantly between the two groups: adjusted least squares mean of 89.5 (95% confidence interval, 86.7-92.3) for children of WWE, compared with adjusted least square mean of 92.0 (95% CI, 86.4-97.6) for children of HW.

Does dopamine dysregulation cause schizophrenia?
Investigators identified a mechanism on the dopamine receptor, known as the autoreceptor, which regulates how much dopamine is released from the presynaptic neuron. Impairment of this autoreceptor leads to poorly controlled dopamine release and excessive dopamine flow.
The researchers found decreased expression of this autoreceptor accounts for the genetic evidence of schizophrenia risk, and, using a suite of statistical routines, they showed that this relationship is probably causative.
“Our research confirms the scientific hypothesis that too much dopamine plays a likely causative role in psychosis and precisely how this is based on genetic factors,” study investigator Daniel Weinberger, MD, director and CEO of the Lieber Institute for Brain Development, Baltimore, told this news organization.
“Drugs that treat psychosis symptoms by simply blocking dopamine receptors have harsh side effects. ... Theoretically, scientists could now develop therapies that target these malfunctioning autoreceptors to treat this devastating condition with fewer side effects,” he said.
The study was published online in Nature Neuroscience.
‘Privileged spot’
“Large international genetic studies known as genomewide association studies have identified hundreds of regions of the human genome housing potential risk genes for schizophrenia,” Dr. Weinberger said.
“However, these regions are still poorly resolved in terms of specific genes, and treatments and diagnostic techniques are far from what they should be.” Moreover, “treatments for schizophrenia address the symptoms of psychosis but not the cause,” he said.
“For more than 70 years, neuroscientists have suspected that dopamine plays a key role in schizophrenia, but what kind of role, exactly, has remained a mystery,” Dr. Weinberger noted. “It occupied a privileged spot in the principal hypothesis about schizophrenia for over 60 years – the so-called ‘dopamine hypothesis.’ ”
Antipsychotic drugs that reduce dopamine “are the principal medical treatments but they cause serious side effects, including an inability to experience pleasure and joy – a sad reality for patients and their families,” he continued.
The current study “set out to understand how dopamine acts in schizophrenia” using “analysis of the genetic and transcriptional landscape” of the postmortem caudate nucleus from 443 donors (245 neurotypical, 154 with schizophrenia, and 44 with bipolar disorder).
Brain samples were from individuals of diverse ancestry (210 were of African ancestry and 2,233 were of European ancestry).
New treatment target?
The researchers performed an analysis of transancestry expression quantitative trait loci, genetic variants that explain variations in gene expression levels, which express in the caudate, annotating “hundreds of caudate-specific cis-eQTLs.”
Then they integrated this analysis with gene expression that emerged from the latest genomewide association study and transcriptome-wide association study, identifying hundreds of genes that “showed a potential causal association with schizophrenia risk in the caudate nucleus,” including a specific isoform of the dopamine D2 receptor, which is upregulated in the caudate nucleus of those with schizophrenia.
“If autoreceptors don’t function properly the flow of dopamine in the brain is poorly controlled and too much dopamine flows for too long,” said Dr. Weinberger.
In particular, they observed “extensive differential gene expression” for schizophrenia in 2,701 genes in those with schizophrenia, compared with those without: glial cell–derived neurotrophic factor antisense RNA was a top-up gene and tyrosine hydroxylase, which is a rate-limiting enzyme in dopamine synthesis, was a down-regulated gene. Dopamine receptors DRD2 and DRD3 were differentially expressed.
Having done this, they looked at the effects of antipsychotic medications that target D2 regions on gene expression in the caudate by testing for differences between individuals with schizophrenia who were taking antipsychotics at the time of death, those not taking antipsychotics at the time of death (n = 104 and 49, respectively), and neurotypical individuals (n = 239).
There were 2,692 differentially expressed genes between individuals taking antipsychotics versus neurotypical individuals (false discovery rate < 0.05). By contrast, there were only 665 differentially expressed genes (FDR < .05) between those not taking antipsychotics and neurotypical individuals.
“We found that antipsychotic medication has an extensive influence on caudate gene expression,” the investigators noted.
They then developed a new approach to “infer gene networks from expression data.” This method is based on deep neural networks, obtaining a “low-dimensional representation of each gene’s expression across individuals.” The representation is then used to build a “gene neighborhood graph and assign genes to modules.”
This method identified “several modules enriched for genes associated with schizophrenia risk.” The expression representations captured in this approach placed genes in “biologically meaningful neighborhoods, which can provide insight into potential interactions if these genes are targeted for therapeutic intervention,” the authors summarized.
“Now that our new research has identified the specific mechanism by which dopamine plays a causative role in schizophrenia, we hope we have opened the door for more targeted drugs or diagnostic tests that could make life better for patients and their families,” Dr. Weinberger said.
No causal link?
Commenting on the study, Rifaat El-Mallakh, MD, director of the mood disorders research program, department of psychiatry and behavioral sciences, University of Louisville (Ky.), called it an “excellent study performed by an excellent research group” that “fills an important lacuna in our research database.”
However, Dr. El-Mallakh, who was not involved in the research, disagreed that the findings show causality. “The data that can be gleaned from this study is limited and the design has significant limitations. As with all genetic studies, this is an association study. It tells us nothing about the cause-effect relationship between the genes and the illness.
“We do not know why genes are associated with the illness. Genetic overrepresentation can have multiple causes, and more so when the data is a convenience sample. As noted by the authors, much of what they observed was probably related to medication effect. I don’t think this study specifically tells us anything clinically,” he added.
The study was supported by the LIBD, the BrainSeq Consortium, an National Institutes of Health fellowship to two of the authors, and a NARSAD Young Investigator Grant from the Brain & Behavior Research Foundation to one of the authors. Dr. Weinberger has reported no relevant financial relationships. Dr. El-Mallakh declared no specific financial relationships relevant to the study but has reported being a speaker for several companies that manufacture antipsychotics.

Mind the geriatrician gap
These should be the best of times for geriatric medicine.
The baby boom has become a senior surge, bringing in a rapidly growing pool of aging patients for geriatricians to treat. According to the U.S. Census Bureau, more than 56 million adults aged 65 and older live in the United States. They account for about 17% of the nation’s population. That number is expected to hit 73 million by 2030 and 86 million by 2050.
The American Geriatrics Society estimates that 30% of older people require the attention of geriatricians. These clinicians excel in managing complex cases – patients with multiple comorbidities, such as coronary artery disease, dementia, and osteoporosis, who are taking a half dozen, and often more, medications.
. In the 2010s, geriatricians called for “25,000 [such specialists] by 2025.” As of 2021, 7123 certified geriatricians were practicing in the United States, according to the American Board of Medical Specialties.
The Health Resources and Services Administration, a federal agency that addresses medical workforce shortages, estimates that there will be 6,230 geriatricians by 2025, or approximately 1 for every 3,000 older adults requiring geriatric care. HRSA projects a shortage of 27,000 geriatricians by 2025.
The specialty has faced an uphill battle to attract fellows. This year, only 43% of the nation’s 177 geriatrics fellowship slots were filled, according to November’s National Resident Match Program report. Family medicine–based geriatrics achieved only a 32% fill rate, while internal medicine–based programs saw a rate of 45%.
“Our numbers are shrinking so we need another approach to make sure older adults get the care they need and deserve,” said G. Michael Harper, MD, president of the 6,000-member AGS.
But Dr. Harper, who practices at the University of California, San Francisco, and the San Francisco VA Medical Center, added a positive note: “We may be struggling to increase the number of board-certified geriatricians, but the field itself has made a lot of progress in terms of improving clinical care through advancements in science and in the ways we deliver care.”
Dr. Harper cited the Hospital Elder Life Program, a hospital model developed at the Harvard-affiliated Marcus Institute for Aging Research, which uses an interprofessional team and trained volunteers to prevent delirium and functional decline. HELP has been adopted by more than 200 hospitals worldwide and has been successful at returning older adults to their homes or previous living situations with maintained or improved ability to function, he said.
Mark Supiano, MD, professor and chief of geriatrics at the University of Utah, Salt Lake City, said the specialty has been in shortage mode since ABMS recognized it in 1988. He was in the initial cohort of fellowship-trained geriatricians, sitting for the first certifying exam in geriatrics offered that year.
“Back then, the demographic imperative of the aging of our society was on the horizon. We’re living it now. I knew enough to recognize it was coming and saw an opportunity,” Dr. Supiano said in an interview. “There was so much then that we didn’t know about how to understand aging or how to care for older adults that there really was such a knowledge gap.”
Dr. Supiano is an associate editor of Hazzard’s Geriatric Medicine and Gerontology (McGraw-Hill Education), which has more than doubled in pages and word count during his career.
Unfavorable finances
Katherine Thompson, MD, director of the geriatrics fellowship program at the University of Chicago and codirector of UChicago’s Successful Aging and Frailty Evaluation Clinic, said money is a major reason for the struggle. “I think probably the biggest driver is financial,” she said. “A lot of people are graduating medical school with really astronomical amounts of medical school loans.”
Geriatricians, like other doctors, carry a large debt – $200,000, on average, not counting undergraduate debt, according to the Association of American Medical Colleges.
But the typical geriatrician earns less than an internist or family medicine doctor who doesn’t undergo the additional year of training, Dr. Thompson said. “There’s not a lot of financial motivation to do this fellowship,” she said.
The jobs website Zippia reports that geriatricians earned roughly $165,000 per year on average in 2022. The average annual incomes in 2022 were $191,000 for pediatricians, $215,000 for family physicians, and $223,000 for internists, according to the site.
In other words, Dr. Harper said, “geriatrics is one of the few professions where you can actually do additional training and make less money.”
The reason for the pay issue is simple: Geriatricians treat patients covered by Medicare, whose reimbursement schedules lag behind those of commercial insurers. The Kaiser Family Foundation reported in 2020 that private insurance paid 143% of Medicare rates on average for physician services.
Dr. Harper said overall compensation for geriatricians has “not gained a lot of traction,” but they can earn comfortable livings.
Still, representation of the specialty on the American Medical Association’s Relative Value Scale Update Committee has led to approval by the Centers for Medicare & Medicaid Services of billing codes that pay geriatricians “for what they do. Examples include chronic care management, advance care planning, and dementia evaluation,” he said.
But the geriatrician gap goes beyond money.
Ageism, too, may play a role in residents not choosing geriatrics.
“Our culture is ageist. It definitely focuses on youth and looks at aging as being loss rather than just a change in what works well and what doesn’t work well,” said Mary Tinetti, MD, a geriatrician and researcher at Yale University, New Haven, Conn. “Ageism happens among physicians, just because they’re part of the broader society.”
Time for a new goal?
Dr. Tinetti said she’s optimistic that new ideas about geriatricians teaching other primary care clinicians about the tenets of geriatric medicine, which offer a wholistic approach to comorbidities, such as diabetes, atrial fibrillation, dementia, hypertension, hyperlipidemia, and polypharmacy problems faced by this population, especially those 85 and older.
She has called on her profession to abandon the goal of increasing the numbers of board-certified geriatricians – whom she refers to as big “G” geriatricians. She instead wants to develop a “small, elite workforce” that discovers and tests geriatrics principles through research, teaches these principles to all healthcare professions and to the public, and disseminates and implements the policies.
“We need a cadre of geriatricians who train all other clinicians in the care of older adults,” Dr. Tinetti said. “The goal is not more geriatricians but rather the preparation of all clinicians in the care of older adults.”
Dr. Thompson said geriatricians are teaching primary care specialists, nurses, social workers, and other health care providers the principles of age-friendly care. AGS has for the past 20 years led a program called the Geriatrics for Specialists Initiative to increase geriatrics knowledge and expertise of surgical and medical specialists.
Some specialties have taken the cue and have added geriatrics-related hyphens through additional training: geriatric-emergency, geriatric-general surgery, geriatric-hospitalists, and more.
HRSA runs programs to encourage physicians to train as geriatricians and geriatrics faculty, and it encourages the geriatrics interdisciplinary team approach.
Richard Olague, director of public affairs for HRSA, said his agency has invested over $160 million over the past 4 years in the education and training of geriatricians and other health care professionals who care for the elderly through its Geriatrics Workforce Enhancement Program and Geriatrics Academic Career Awards Program. In the academic year 2020-2021, the two programs trained 109 geriatricians; 456 other geriatric/gerontology providers and students; 44,450 other healthcare workforce professionals and students; and served 17,666 patients and 5,409 caregivers.
Dr. Harper, like his fellow geriatricians, tells young doctors that geriatrics is a fulfilling specialty.
“I get to care for the whole person and sometimes their families, too, and in the process form rich and meaningful relationships. And while I’m rarely in the position to cure, I always have the ability to care,” he said. “Sometimes that can mean being an advocate trying to make sure my patients receive the care they need, and other times it might mean protecting them from burdensome care that is unlikely to lead to any meaningful benefit. There is great reward in all of that.”
Dr. Supiano said geriatric patients are being helped by the Age-Friendly Health System initiative of the John A. Hartford Foundation and the Institute for Healthcare Improvement in partnership with the American Hospital Association and the Catholic Health Association of the United States. This is sort of a seal of approval for facilities committed to age-friendly care.
“When you go to your hospital, if they don’t have this age-friendly health system banner on the front door ... you either ask why that is not there, or you vote with your feet and go to another health system that is age friendly,” he said. “Geriatricians are eternal optimists.”

These should be the best of times for geriatric medicine.
The baby boom has become a senior surge, bringing in a rapidly growing pool of aging patients for geriatricians to treat. According to the U.S. Census Bureau, more than 56 million adults aged 65 and older live in the United States. They account for about 17% of the nation’s population. That number is expected to hit 73 million by 2030 and 86 million by 2050.
The American Geriatrics Society estimates that 30% of older people require the attention of geriatricians. These clinicians excel in managing complex cases – patients with multiple comorbidities, such as coronary artery disease, dementia, and osteoporosis, who are taking a half dozen, and often more, medications.
. In the 2010s, geriatricians called for “25,000 [such specialists] by 2025.” As of 2021, 7123 certified geriatricians were practicing in the United States, according to the American Board of Medical Specialties.
The Health Resources and Services Administration, a federal agency that addresses medical workforce shortages, estimates that there will be 6,230 geriatricians by 2025, or approximately 1 for every 3,000 older adults requiring geriatric care. HRSA projects a shortage of 27,000 geriatricians by 2025.
The specialty has faced an uphill battle to attract fellows. This year, only 43% of the nation’s 177 geriatrics fellowship slots were filled, according to November’s National Resident Match Program report. Family medicine–based geriatrics achieved only a 32% fill rate, while internal medicine–based programs saw a rate of 45%.
“Our numbers are shrinking so we need another approach to make sure older adults get the care they need and deserve,” said G. Michael Harper, MD, president of the 6,000-member AGS.
But Dr. Harper, who practices at the University of California, San Francisco, and the San Francisco VA Medical Center, added a positive note: “We may be struggling to increase the number of board-certified geriatricians, but the field itself has made a lot of progress in terms of improving clinical care through advancements in science and in the ways we deliver care.”
Dr. Harper cited the Hospital Elder Life Program, a hospital model developed at the Harvard-affiliated Marcus Institute for Aging Research, which uses an interprofessional team and trained volunteers to prevent delirium and functional decline. HELP has been adopted by more than 200 hospitals worldwide and has been successful at returning older adults to their homes or previous living situations with maintained or improved ability to function, he said.
Mark Supiano, MD, professor and chief of geriatrics at the University of Utah, Salt Lake City, said the specialty has been in shortage mode since ABMS recognized it in 1988. He was in the initial cohort of fellowship-trained geriatricians, sitting for the first certifying exam in geriatrics offered that year.
“Back then, the demographic imperative of the aging of our society was on the horizon. We’re living it now. I knew enough to recognize it was coming and saw an opportunity,” Dr. Supiano said in an interview. “There was so much then that we didn’t know about how to understand aging or how to care for older adults that there really was such a knowledge gap.”
Dr. Supiano is an associate editor of Hazzard’s Geriatric Medicine and Gerontology (McGraw-Hill Education), which has more than doubled in pages and word count during his career.

Ohio measles outbreak sickens nearly 60 children
None of the children had been fully vaccinated against measles, and 23 of them have been hospitalized, local officials report.
“Measles can be very serious, especially for children under age 5,” Columbus Public Health spokesperson Kelli Newman told CNN.
Nearly all of the infected children are under age 5, with 12 of them being under 1 year old.
“Many children are hospitalized for dehydration,” Ms. Newman told CNN in an email. “Other serious complications also can include pneumonia and neurological conditions such as encephalitis. There’s no way of knowing which children will become so sick they have to be hospitalized. The safest way to protect children from measles is to make sure they are vaccinated with MMR.”
Of the 59 infected children, 56 were unvaccinated and three had been partially vaccinated. The MMR (measles, mumps, and rubella) vaccine is recommended for children beginning at 12 months old, according to the Centers for Disease Control and American Academy of Pediatrics. Two doses are needed to be considered fully vaccinated, and the second dose is usually given between 4 and 6 years old.
Measles “is one of the most infectious agents known to man,” the academy says.
It is so contagious that if one person has it, up to 9 out of 10 people around that person will also become infected if they are not protected, the CDC explains. Measles infection causes a rash and a fever that can spike beyond 104° F. Sometimes, the illness can lead to brain swelling, brain damage, or death.
Last month, the World Health Organization and CDC warned that 40 million children worldwide missed their measles vaccinations in 2021, partly due to pandemic disruptions. The American Academy of Pediatrics also notes that many parents choose not to vaccinate their children due to misinformation.
Infants are at heightened risk because they are too young to be vaccinated.
The academy offered several tips for protecting unvaccinated infants during a measles outbreak:
- Limit your baby’s exposure to crowds, other children, and people with cold symptoms.
- Disinfect objects and surfaces at home regularly, because the measles virus can live on surfaces or suspended in the air for 2 hours.
- If possible, feed your baby breast milk, because it has antibodies to prevent and fight infections.

Ultraprocessed foods tied to faster rate of cognitive decline
Results from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), which included more than 10,000 people aged 35 and older, showed that higher intake of UPF was significantly associated with a faster rate of decline in executive and global cognitive function.
“These findings show that lifestyle choices, particularly high intake of ultraprocessed foods, can influence our cognitive health many years later,” coinvestigator Natalia Goncalves, PhD, University of São Paulo, Brazil, said in an interview.
The study was published online in JAMA Neurology.
The study’s findings were presented in August at the Alzheimer’s Association International Conference (AAIC) 2022 and were reported by this news organization at that time.
High sugar, salt, fat
The new results align with another recent study linking a diet high in UPFs to an increased risk for dementia.
UPFs are highly manipulated, are packed with added ingredients, including sugar, fat, and salt, and are low in protein and fiber. Examples of UPFs are soft drinks, chips, chocolate, candy, ice cream, sweetened breakfast cereals, packaged soups, chicken nuggets, hot dogs, and fries.
The ELSA-Brasil study comprised 10,775 adults (mean age, 50.6 years at baseline; 55% women; 53% White) who were evaluated in three waves approximately 4 years apart from 2008 to 2017.
Information on diet was obtained via food frequency questionnaires and included details regarding consumption of unprocessed foods, minimally processed foods, and UPFs.
Participants were grouped according to UPF consumption quartiles (lowest to highest). Cognitive performance was evaluated by use of a standardized battery of tests.
During median follow-up of 8 years, people who consumed more than 20% of daily calories from UPFs (quartiles 2-4) experienced a 28% faster rate of decline in global cognition (beta = –0.004; 95% confidence interval [CI], –0.006 to –0.001; P = .003) and a 25% faster rate of decline in executive function (beta = –0.003, 95% CI, –0.005 to 0.000; P = .01) compared to peers in quartile 1 who consumed less than 20% of daily calories from UPFs.
The researchers did not investigate individual groups of UPFs.
However, Dr. Goncalves noted that some studies have linked the consumption of sugar-sweetened beverages with lower cognitive performance, lower brain volume, and poorer memory performance. Another group of ultraprocessed foods, processed meats, has been associated with increased all-cause dementia and Alzheimer’s disease.
Other limitations include the fact that self-reported diet habits were assessed only at baseline using a food frequency questionnaire that was not designed to assess the degree of processing.
While analyses were adjusted for several sociodemographic and clinical confounders, the researchers said they could not exclude the possibility of residual confounding.
Also, since neuroimaging is not available in the ELSA-Brasil study, they were not able to investigate potential mechanisms that could explain the association between higher UPF consumption and cognitive decline.
Despite these limitations, the researchers said their findings suggest that “limiting UPF consumption, particularly in middle-aged adults, may be an efficient form to prevent cognitive decline.”
Weighing the evidence
Several experts weighed in on the results in a statement from the UK nonprofit organization, Science Media Centre.
Kevin McConway, PhD, with Open University, Milton Keynes, England, said it’s important to note that the study suggests “an association, a correlation, and that doesn’t necessarily mean that the cognitive decline was caused by eating more ultra-processed foods.”
He also noted that some types of cognitive decline that are associated with aging occurred in participants in all four quartiles, which were defined by the percentage of their daily energy that came from consuming UPFs.
“That’s hardly surprising – it’s a sad fact of life that pretty well all of us gradually lose some of our cognitive functions as we go through middle and older age,” Dr. McConway said.
“The study doesn’t establish that differences in speed of cognitive decline are caused by ultra-processed food consumption anyway. That’s because it’s an observational study. If the consumption of ultra-processed food causes the differences in rate of cognitive decline, then eating less of it might slow cognitive decline, but if the cause is something else, then that won’t happen,” Dr. McConway added.
Gunter Kuhnle, PhD, professor of nutrition and food science, University of Reading, England, noted that UPFs have become a “fashionable term to explain associations between diet and ill health, and many studies have attempted to show associations.
“Most studies have been observational and had a key limitation: It is very difficult to determine ultra-processed food intake using methods that are not designed to do so, and so authors need to make a lot of assumptions. Bread and meat products are often classed as ‘ultra-processed,’ even though this is often wrong,” Dr. Kuhnle noted.
“The same applies to this study – the method used to measure ultra-processed food intake was not designed for that task and relied on assumptions. This makes it virtually impossible to draw any conclusions,” Dr. Kuhnle said.
Duane Mellor, PhD, RD, RNutr, registered dietitian and senior teaching fellow, Aston University, Birmingham, England, said the study does not change how we should try to eat to maintain good brain function and cognition.
“We should try to eat less foods which are high in added sugar, salt, and fat, which would include many of the foods classified as being ultra-processed, while eating more in terms of both quantity and variety of vegetables, fruit, nuts, seeds, and pulses, which are known to be beneficial for both our cognitive and overall health,” Dr. Mellor said.
The ELSA-Brasil study was supported by the Brazilian Ministry of Health, the Ministry of Science, Technology and Innovation, and the National Council for Scientific and Technological Development. The authors as well as Dr. McConway, Dr. Mellor, and Dr. Kuhnle have disclosed no relevant financial relationships.

Results from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), which included more than 10,000 people aged 35 and older, showed that higher intake of UPF was significantly associated with a faster rate of decline in executive and global cognitive function.
“These findings show that lifestyle choices, particularly high intake of ultraprocessed foods, can influence our cognitive health many years later,” coinvestigator Natalia Goncalves, PhD, University of São Paulo, Brazil, said in an interview.
The study was published online in JAMA Neurology.
The study’s findings were presented in August at the Alzheimer’s Association International Conference (AAIC) 2022 and were reported by this news organization at that time.
High sugar, salt, fat
The new results align with another recent study linking a diet high in UPFs to an increased risk for dementia.
UPFs are highly manipulated, are packed with added ingredients, including sugar, fat, and salt, and are low in protein and fiber. Examples of UPFs are soft drinks, chips, chocolate, candy, ice cream, sweetened breakfast cereals, packaged soups, chicken nuggets, hot dogs, and fries.
The ELSA-Brasil study comprised 10,775 adults (mean age, 50.6 years at baseline; 55% women; 53% White) who were evaluated in three waves approximately 4 years apart from 2008 to 2017.
Information on diet was obtained via food frequency questionnaires and included details regarding consumption of unprocessed foods, minimally processed foods, and UPFs.
Participants were grouped according to UPF consumption quartiles (lowest to highest). Cognitive performance was evaluated by use of a standardized battery of tests.
During median follow-up of 8 years, people who consumed more than 20% of daily calories from UPFs (quartiles 2-4) experienced a 28% faster rate of decline in global cognition (beta = –0.004; 95% confidence interval [CI], –0.006 to –0.001; P = .003) and a 25% faster rate of decline in executive function (beta = –0.003, 95% CI, –0.005 to 0.000; P = .01) compared to peers in quartile 1 who consumed less than 20% of daily calories from UPFs.
The researchers did not investigate individual groups of UPFs.
However, Dr. Goncalves noted that some studies have linked the consumption of sugar-sweetened beverages with lower cognitive performance, lower brain volume, and poorer memory performance. Another group of ultraprocessed foods, processed meats, has been associated with increased all-cause dementia and Alzheimer’s disease.
Other limitations include the fact that self-reported diet habits were assessed only at baseline using a food frequency questionnaire that was not designed to assess the degree of processing.
While analyses were adjusted for several sociodemographic and clinical confounders, the researchers said they could not exclude the possibility of residual confounding.
Also, since neuroimaging is not available in the ELSA-Brasil study, they were not able to investigate potential mechanisms that could explain the association between higher UPF consumption and cognitive decline.
Despite these limitations, the researchers said their findings suggest that “limiting UPF consumption, particularly in middle-aged adults, may be an efficient form to prevent cognitive decline.”
Weighing the evidence
Several experts weighed in on the results in a statement from the UK nonprofit organization, Science Media Centre.
Kevin McConway, PhD, with Open University, Milton Keynes, England, said it’s important to note that the study suggests “an association, a correlation, and that doesn’t necessarily mean that the cognitive decline was caused by eating more ultra-processed foods.”
He also noted that some types of cognitive decline that are associated with aging occurred in participants in all four quartiles, which were defined by the percentage of their daily energy that came from consuming UPFs.
