Among people with Alzheimer Disease, the risk of developing a stroke is significantly greater if they are using antiepileptic drugs, according to a large study published in the Journal of the American Heart Association.

• The Medication Use and Alzheimer’s Disease cohort, which includes all the people in Finland who have been clinically diagnosed with Alzheimer disease (70,718) from 2005 to 2011, was analyzed to look for a correlation between the disease and antiepileptic drug use.
• Patients who had used the medications were about 37% more likely to have experienced a stroke, compared to nondrug users (hazard ratio [HR], 1.37).
• The likelihood of having a stroke in this patient population was greatest during the first 3 months of taking antiepileptic medication (HR, 2.36).
• The association between drug use and ischemic stroke was less than that observed between drug use and hemorrhagic stroke (HR, 1.34 vs 1.44).

Standard depth invasive electrodes are typically used to precisely locate areas of the brain that are responsible for seizures in patients with medically refractory epilepsy, but a recent analysis suggests that hybrid depth microwire electrodes may be just as effective and just as safe.

• Investigators at Cedars-Sinai Medical Center reviewed 53 cases of refractory epilepsy who had surgery between 2006 and 2017.
• The analysis included 555 electrodes and revealed a complication rate of 2.3% per electrode and a per case rate of 20.8%; no infections or deaths were reported.
• The researchers did not uncover a difference in complication rates between standard and hybrid depth electrodes.
• Hybrid depth electrodes were as reliable as standard electrodes in pinpointing seizure onset zones.

Children with autism who also have an abnormal EEG or epilepsy are more likely to experience problems with developmental and adaptive functioning, according to an analysis of 443 patients with autism spectrum disorder (ASD).

• The medical records of children with autism were reviewed by researchers at Cincinnati Children’s Hospital Medical Center.
• The children were divided into 3 categories: those with ASD, no epilepsy, and abnormal EEG results; those with ASD, no epilepsy, and normal EEG; and those with ASD and epilepsy.
• Among 372 patients with ASD without epilepsy, 25.5% had an abnormal EEG; these patients were more likely to have more impaired adaptive functioning when compared to patients with normal EEG readings.
• Children with abnormal EEG readings presented with similar abnormalities to the group with epilepsy.
• Patients with epilepsy had lower scores on all the tests that measure developmental and adaptive functioning, when compared to those with normal EEG readings.

Pediatric patients who have been initially diagnosed with epilepsy with myoclonic-atonic seizures (EMAS) are likely to be switched to another diagnosis over time, according to a retrospective chart analysis of 77 children at Children’s Hospital of Colorado.

• Over 50% of patients in this study were switched from suspected EMAS to another epilepsy diagnosis.
• Among the 77 patients, 30 had an initial diagnosis of EMAS and 57 had a final diagnosis of EMAS.
• Among 65% of patients who had more than one diagnosis over time, the first, second, and third diagnoses were provided within 1 year, 3 years, and 10 years after the onset of the disease.
• Signs of Lennox-Gastaut syndrome (LGS), including paroxysmal fast activity, slow spike-and-wave, and tonic seizure, were detected in 50% of the 77 patients but only a minority received a final diagnosis of LGS.

Researchers have found that using 256-channel high-density EEG and high-resolution head models of individual patients can help establish precise electrical source imaging of oscillatory features of the onset of a seizure, which in turn improves presurgical planning. Precisely localizing the seizure onset zone in the cortex is important for the best surgical outcomes.

• Using noninvasive electrical source imaging to plan surgery has proven problematic to date because of the interference of noise artifacts and non-seizure activity, which can be superimposed over the seizure signal.
• In this study, high density EEG was combined with exact sensor positioning and individual electrical head models, which were derived from T1 MRI results.
• Among 84 seizures, investigators were able to localize the onset of 56.
• High density EEG with interictal spikes was more accurate than international 10-20 EEG for interictal spikes and ictal onset.

The cortical regions of the brains of patients with juvenile myoclonic epilepsy (JME) are more likely to be disassociated from subcortical structures, according to a recent study that compared the MRI readings of JME patients to those of normal children. 

• Investigators from the University of Wisconsin School of Medicine compared 21 children with JME to 22 healthy controls over a 2 year period.
• Normal children had modular cortical development and network integration between cortical and subcortical regions.
• Patients with epilepsy had a less modular cortical network that was disassociated from subcortical structures.
• Children with JME were also found to have weaker modules or communities, as indicated by higher clustering and lower modularity indices.

Pediatric status epilepticus (SE) is an expensive disorder and is not uncommon in this patient population, according to a recent review of the medical literature.

• Gurcharran et al note that pediatric SE occurs in about 20per 100,000 children each year.
• The disorder carries a mortality of 3%.
• The most common risk factor for morbidity and death is symptomatic etiology, with acute presentation more common than remote.
• A single episode of status epilepticus costs more than $10,000 to manage and can reach more than $100,000 in children with refractory disease.
• The most common cause of the condition is febrile SE, which usually occurs in early childhood.

While several emerging treatments have been recommended for children with refractory status epilepticus, most of the research supporting these modalities are anecdotal in nature, according to a review published in Seizure.

• Randomized controlled trials have evaluated hypothermia and found it is no more effective than placebo for refractory status epilepticus (RSE) and super-refractory status epilepticus (SRSE).
• Case series have suggested that a ketogenic diet may benefit children with RSE.
• A few case reports involving the ketogenic diet found seizures were stopped within a week in 20-90% of children.
• One double blind trial concluded that brexanolone was no more effective than placebo for weaning patients off 3^rd line anesthetic agents and freedom from RSE after 24 hours.

Patients will likely develop intolerable psychiatric and behavioral side effects (IPBSE) to an antiepileptic drug if they are already sensitive to another one, according to researchers from Yale and Columbia University.

• A review of the records of over 2,000 patients found that about 20% were taking at least two antiepileptic drug and had at IPBSE to at least one of the drugs.
• Cross sensitivity was detected between zonisamide and levetiracetam.
• The odds of developing said side effects from levetiracetam or from zonisamide were significantly higher in a patient that had had a side effect to another antiepileptic drug than in patients who had no IPBSE to other antiepileptic drugs (20.5% versus 7.5%.)
•  A history of depression and psychosis increase the risk of IPBSE among patients taking antiepileptic medication.

Periictal cardiorespiratory dysfunction, sleep-disordered breathing, and endocrine dysfunction have all been linked to sudden unexpected death from epilepsy (SUDEP).

• Investigators conducted a prospective observational study on 30 patients in the Columbia University Medical Center’s adult epilepsy monitoring unit.
• Their analysis found that patients who were at high risk for SUDEP were more likely to experience cardiorespiratory dysfunction (60% vs 27%).
• Sleep-disordered breathing was found in 88% of patients with inpatient or outpatient polysomnography results that were fully scorable.
• The researchers also found endocrine dysfunction in 35% of patients, with men more likely to experience the problem.
• The analysis did not detect a significant relationship between cardiorespiratory dysfunction, sleep-disordered breathing, and neuroendocrine status.
