Use of the Sleep Apnea Scale of the Sleep Disorders Questionnaire (SA-SDQ) in adults with epilepsy.
A growing body of literature supports the importance of sleep comorbidities in epilepsy. The prevalence of obstructive sleep apnea (OSA) in adults with epilepsy exceeds that of the general population, and its presence adversely impacts seizure control in some cases. The Sleep Apnea Scale of the Sleep Disorders Questionnaire (SA-SDQ) is a 12-item screening instrument generally used in clinical research. One prior study suggested modified cutoffs for the prediction of OSA in adults with epilepsy using this instrument. Our purpose was to further investigate the validity of the SA-SDQ in adults with epilepsy. ⋯ Our work confirms the validity of the SA-SDQ as a screening instrument for OSA in clinical research involving adults with epilepsy. Further, our findings support the use of cutoffs lower than those applied to the general population and a single cutoff score (25) for predicting any severity of OSA in adults with epilepsy.

Why do people Google epilepsy? An infodemiological study of online behavior for epilepsy-related search terms.
Millions of people worldwide use the Internet daily as a source of health information. Google is the most popular search engine and is used by patients and physicians to search for online health-related information. This study aimed to evaluate changes in web search behavior occurring in English-speaking countries over time for terms related to epilepsy and epileptic seizures. ⋯ The volume of searches for the term "epilepsy SUDEP" was found to be enormously increased over time. Most people appear to use search engines to look for terms related to epilepsy to obtain information on seizure symptoms, possibly to aid initial self-diagnosis. Fears and worries about epileptic seizures and news on celebrities with epilepsy seem to be major factors that influence online search behavior.

Lesion side matters - an fMRI study on the association between neural correlates of watching dynamic fearful faces and their evaluation in patients with temporal lobe epilepsy.
Most studies assessing facial affect recognition in patients with TLE reported emotional disturbances in patients with TLE. Results from the few fMRI studies assessing neural correlates of affective face processing in patients with TLE are divergent. Some, but not all, found asymmetrical mesiotemporal activations, i.e., stronger activations within the hemisphere contralateral to seizure onset. ⋯ Although we found stronger activations within the contralateral mesial temporal lobe in the majority of all patients, our results suggest that only in the event of left-sided mesiotemporal damage is the right mesial temporal lobe able to preserve intact facial fear recognition. In the event of right-sided mesiotemporal damage, fear recognition is disturbed. This underlines the hypothesis that the right amygdala is biologically predisposed to processing fear, and its function cannot be fully compensated in the event of right-sided mesiotemporal damage.

Lead revision surgery for vagus nerve stimulation in epilepsy: outcomes and efficacy.
We present, to our knowledge, the first published analysis of vagus nerve stimulation (VNS) lead revisions to incorporate quality of life, clinical response, and antiepileptic drug (AED) burden in postrevision clinical outcomes. Ten patients were followed and had no postoperative complications. Seven patients had improvement in quality of life, and three experienced no change. ⋯ Seven patients reported 30-60% improvement in seizure reduction, two experienced >60%, and one noted <30%. Six patients had no change in AED burden. Vagus nerve stimulation lead revision should be considered a safe option for patients with VNS lead failure and medically intractable epilepsy.
