Abstract:
Transient global amnesia(TGA) is not a rare event in the elderly, which is characterized by transient inability to form the new memory traces plus retrograde amnesia with benign prognosis. The etiology is unknown, but suggested causes have included transient ischemic attack, migraine, epilepsy, brain tumor, drug intoxication, other toxic/metabolic disturbances, or hysteria. Especially, TGA associated with ischemic stroke is important on the elderly patients and necessary to be differentiated with other causes, for stroke prevention. As far as we know, the case of TGA due to cerebral infarction confirmed by brain imaging study is extremely rare in the literature. We report the case of 67 year-old female patient with typical TGA showing ischemic lesion on the right temporal area on MRI and discussed its significance as one of the cause of TGA.
