초록
Transient global amnesia refers to a syndrome of temporary anterograde and retrograde memory loss with preservation of alertness, attention, and self-identity without other significant accompanying neurologic symptoms. We report a case of transient global amnesia immediately after cerebral angiography. A 72-year-old woman presented with left side weakness and dysarthria. Cerebral angiography was performed to evaluate cerebral vascular abnormality. The symptoms of transient global amnesia were noted immediately after angiography. Diffusion weighted MRI showed several tiny infarcts in the territory of posterior circulation. Ischemia from cerebral emboli may have caused transient global amnesia precipitated by cerebral angiography.
