[Transient epileptic amnesia].

Abstract

Transient epileptic amnesia (TEA) is a sub-type of mesial temporal lobe epilepsy, with amnesic seizures. TEA is characterized by recurrent episodes of amnesia. Diagnostic criteria are available for TEA, and these memory disturbances should not be misdiagnosed with transient global amnesia. The neuropsychological evaluation is normal, however, autobiographical memory impairment is present in 70% of the cases and accelerated long term forgetting in 44%. When a patient complains of memory disturbances, especially autobiographical memory, TEA must be considered especially if there was an amnesic episode and symptoms that suggest temporal epilepsia. Video electroencephalography monitoring of sleep is a precious diagnostic tool, as epileptiform activities are found during sleep in 83% cases. TEA is pharmaco-sensitive, with full treatment response in 73 to 96% of the cases.
