Polysomnographic recordings were performed in 50 children free from any familial or personal history of seizure or neurologic diseases to evaluate the frequency of epileptiform and unusual electroencephalographic patterns in a normal population. A 9-year-old boy exhibited focal spikes that became bilateral with a density of 24% to 32% during slow wave sleep, and another boy showed a few spikes during slow wave sleep. In seven cases, 14- and 6-Hz rhythms were recorded, mostly in rapid eye movement sleep. A right rhythmic and temporal discharge was observed in one girl. Epileptiform electroencephalographic patterns are not infrequent, and 14- and 6-Hz rhythms during rapid eye movement sleep are common in normal children.

Stretch syncope (SS) is a benign, uncommon, distinct condition described mainly in adolescent males. It is responsible for paroxysmal events started by stereotyped stretching actions with neck hyperextension, culminating in alteration of consciousness. Motor manifestations are often present and may be associated with a generalized slowing of the electroencephalographic activity, challenging the diagnosis.

A case of Kloos syndrome is presented, a rare psychopathological manifestation in psychiatry characterized by the experience of "time paralysis" related to an epileptic focus in the left temporoparietal areas. This syndrome was identified through a detailed psychopathological analysis and detected by an electroencephalographic record. The patient's symptoms disappeared after receiving antiepileptic treatment with Carbamazepine.

The present study reports the results of an electrophysiological analysis of sleep in the East African root rat, Tachyoryctes splendens, belonging to the rodent subfamily Spalacinae. Telemetric electroencephalographic (EEG) and electromyographic recordings, with associated video recording, on three root rats over a continuous 72 h period (12 h light/12 h dark cycle) were analyzed. The analysis revealed that the East African root rat has a total sleep time (TST) of 8.

Background: Seizures are reported in about one-third of patients with severe liver disease in association with acute or chronic liver failure. The majority of the seizures are of focal type. Occasionally generalized tonic-clonic seizures are seen when there is ethanol withdrawal.
View Article and Find Full Text PDFBackground: Secondary mania refers to a manic episode that arises during a medical illness other than bipolar disorder or in response to a drug or medication. As the psychopathological features of secondary mania resemble those of mania due to bipolar disorder, misdiagnosis is frequent.
Purpose And Basic Procedures: We present the case of a 20-year-old woman who developed a manic episode with psychotic symptoms, in whom polymicrogyria, a malformation of the cortical development with abnormal electroencephalographic activity, was documented.
