Depression, traumatic dissociation and epileptic-like phenomena.
OBJECTIVES According to recent findings trauma and stress are important etiological factors in pathogenesis of depression. As characteristic features of depressive cognition have been reported intrusive thoughts and memory disturbances similar to posttraumatic symptoms known in patients with posttraumatic stress disorder or dissociative disorders. Hypothetically is also suggested a close relati...
متن کاملEpileptic phenomena in bismuth toxic encephalopathy.
Seventy patients admitted to hospital with bismuth encephalopathy had repeated clinical and EEG examinations. All the patients exhibited myoclonic jerks, but no paroxysmal features ever appeared on EEG. Computed tomography showed cortical hyperdensities. Seizures were observed in 22 patients, but epileptic EEG patterns appeared only when the bismuth blood level was below 1500 microgram/1. It is...
متن کاملEpileptic Seizure Prediction by Exploiting Signal Transitions Phenomena
A seizure prediction method is proposed by extracting global features using phase correlation between adjacent epochs for detecting relative changes and local features using fluctuation/ deviation within an epoch for determining fine changes of different EEG signals. A classifier and a regularization technique are applied for the reduction of false alarms and improvement of the overall predicti...
متن کاملPallister-Killian syndrome: an unusual cause of epileptic spasms.
Pallister-Killian syndrome (PKS) is a rare, sporadic, genetic disorder characterized by dysmorphic features, learning disability, and epilepsy. It is caused by a mosaic supernumerary isochromosome 12p (i[12p]). The i(12p) is rarely found in peripheral blood but it is present in skin fibroblasts. Recognition is essential for cytogenetic diagnosis. We describe a male aged 2 years 6 months and a f...
متن کاملDynamics of non-convulsive epileptic phenomena modeled by a bistable neuronal network.
It is currently believed that the mechanisms underlying spindle oscillations are related to those that generate spike and wave (SW) discharges. The mechanisms of transition between these two types of activity, however, are not well understood. In order to provide more insight into the dynamics of the neuronal networks leading to seizure generation in a rat experimental model of absence epilepsy...
