Persons with epilepsy experience déjà vu phenomena with or without seizure recognition. Déjà vu experiences are also common mental phenomena in nonclinical individuals. The purpose of this study was to clarify two forms of déjà vu experiences in persons with epilepsy. ⋯ The NSR form was significantly associated with idiopathic generalized epilepsies, less frequent antiepileptic drug administration, and no mesial temporal sclerosis. Although there was a significant association between the frequency of the SR form and patients' habitual seizures, the frequency of the NSR form was not associated with the frequency of the patients' habitual seizures. Persons with epilepsy experience two forms of déjà vu which are differently associated with their seizure recognition.

ReviewPhenomenology of hallucinations, illusions, and delusions as part of seizure semiology.
In partial epilepsy, a localized hypersynchronous neuronal discharge evolving into a partial seizure affecting a particular cortical region or cerebral subsystem can give rise to subjective symptoms, which are perceived by the affected person only, that is, ictal hallucinations, illusions, or delusions. When forming the beginning of a symptom sequence leading to impairment of consciousness and/or a classic generalized seizure, these phenomena are referred to as an epileptic aura, but they also occur in isolation. They often manifest in the fully awake state, as part of simple partial seizures, but they also can be associated to different degrees of disturbed consciousness. ⋯ Here we suggest a classification into elementary sensory, complex sensory, and complex integratory seizure symptoms. Epileptic hallucinations, illusions, and delusions shine interesting light on the physiology and functional anatomy of brain regions involved and their functions in the human being. This article, in which 10 cases are described, introduces the fascinating phenomenology of subjective seizure symptoms.

Case ReportsPassive real-time identification of speech and motor cortex during an awake craniotomy.
Precise localization of eloquent cortex is a clinical necessity prior to surgical resections adjacent to speech or motor cortex. In the intraoperative setting, this traditionally requires inducing temporary lesions by direct electrocortical stimulation (DECS). In an attempt to increase efficiency and potentially reduce the amount of necessary stimulation, we used a passive mapping procedure in the setting of an awake craniotomy for tumor in two patients resection. ⋯ SIGFRIED, a procedure for real-time event detection, was used to identify areas of cortical activation by detecting task-related modulations in the ECoG high gamma band. SIGFRIED's real-time output quickly localized motor and speech areas of cortex similar to those identified by DECS. In conclusion, real-time passive identification of cortical function using SIGFRIED may serve as a useful adjunct to cortical stimulation mapping in the intraoperative setting.

Self-esteem and sense of coherence in young people with uncomplicated epilepsy: a 5-year follow-up.
It is not clear how the psychosocial well-being of young people with epilepsy is affected by growing up with the condition. We studied self-esteem and sense of coherence in a group of young adults with epilepsy and compared the results with those obtained 5 years earlier. ⋯ We found that there was a decline in both sense of coherence and self-esteem over time for young adults with epilepsy. Growing up with epilepsy can lead to impairment of sense of coherence. Sense of coherence does not significantly correlate with epilepsy-related factors, but mirrors the phenomenon of epilepsy. Self-esteem is associated with such epilepsy-related factors as seizure frequency.

Disparities in injury death location for people with epilepsy/seizures.
Wide variation has been reported in the proportion of injury deaths occurring during the prehospital phase. Potential disparities in where injured people with epilepsy and seizure disorders die have not been examined. We compared location of death between injured patients with epilepsy and seizure disorders and similar patients without epilepsy/seizures and tested the hypothesis that injured people with epilepsy/seizures are more likely to die outside of a hospital or health care setting. ⋯ Disparities in where injured people with epilepsy/seizures die deserve further attention. Identifying the underlying causes of these disparities will allow for the development of targeted prevention interventions.
