We overview transient epileptic amnesia and present a case report of 66-year-old right-handed man with severe retrograde amnesia after epileptic seizure. Transient epileptic amnesia (TEA) is a subtype of temporal lobe epilepsy, which is characterised by accelerated-long-term forgetting and autobiographical amnesia, anterograde memory usually is intact. From the available data, no other clinical features clearly distinguish this subpopulation. TEA is usually a syndrome of middle to old age with duration of duration of amnestic attacks for each case can be less than 1 min and longer than 24 hours. The sex ratio of TEA cases is approximately two males to one female. Complete cessation of transient amnesic episodes can be achieved with anticonvulsant therapy. Our patient improved after introduction of treatment with lamotrigine and piracetam.
