- Abstract
- Transient global amnesia (TGA) is an amnesic disorder which is characterized by temporary loss of anterograde and recent retrograde memory with preserved consciousness. Though the pathogenesis of TGA is still unclear, current hypotheses include migraine, seizure, or cerebral ischemia. We present three patients with TGA who showed signal intensity change in diffusion weighted image in hippocampus. These findings might suggest that ischemia in hippocampus might be the cause of the TGA. KeyWords:Transient global amnesia, Diffusion weighted image, Hippocampus
