- Abstract
- Transient global amnesia (TGA) causes retrograde amnesia, but there have been few reports of retrograde amnesia as a presenting symptom in TGA. A 52-year-old male who had acute amnesia for the past 4?years presented with TGA and recovered within 1?day. Brain magnetic resonance imaging revealed a lesion in the left hippocampus, and brain single-photon emission computed tomography revealed decreased blood flow in the left temporal and frontal areas. We speculated that hippocampal lesion with a frontal perfusion defect can be a cause of TGA. KeyWords:Retrograde amnesia, Transient global amnesia, Hippocampus
