Objective: To obtain perspective on epilepsy in patients referred to tertiary centers in France, and describe etiology, epilepsy syndromes, and identify factors of drug resistance and comorbidities.
Methods: We performed a cross-sectional analysis of the characteristics of 5,794 pediatric and adult patients with epilepsy included in a collaborative database in France between 2007 and 2013. Comparisons between groups used Student's t-test or Fisher's exact test for binary or categorical variables.
Sleep-related Cognitions Mediate the Impact of Neuroticism on Insomnia.
Am J Health Behav
September 2015
Objectives: Our study aimed to explore how neuroticism and neuroticism-related traits as well as sleep-related cognitions (dysfunctional beliefs and subjective quality of sleep) influence the emergence of insomnia using a mediational model.
Methods: A cross-sectional study was conducted in which 159 insomniac patients paired with 159 normal sleepers in sex and age (N = 318) completed an online questionnaire.
Results: At the global level, dysfunctional beliefs and poor subjective quality of sleep mediated the neuroticism-insomnia path; at the trait-specific level, these variables mediated the anxiety-insomnia path and partially mediated the effects of vulnerability and self-consciousness on insomnia; some other relations were essentially indirect effects (between depression and insomnia).
Article Synopsis
- A case study is presented of a pacemaker patient who experienced a complete atrioventricular block during a video-polysomnography, coinciding with an electrical seizure, despite showing no symptoms.
- The patient had a history of recurrent syncope previously attributed to convulsive vasovagal syncope connected to heart issues.
- This raises crucial awareness among physicians that cardiac-related syncope can mimic epilepsy, challenging the traditional understanding of epilepsy-like syncope.
Purpose: Failure of anterior temporal lobectomy for temporal lobe epilepsy has raised the question of insular cortex involvement in these seizures. Because of difficulties in exploring the insula with invasive electroencephalography (EEG) recordings, only few studies have been performed and this question remains unanswered.
Methods: Here, we studied 17 patients who underwent surgery for drug-resistant temporal lobe epilepsy, explored with intracerebral electrodes, with at least one electrode coplanar to the insula.
