Transient global amnesia (TGA) is a clinical syndrome characterized by sudden-onset anterograde amnesia, accompanied by repetitive questioning, sometimes with a retrograde component, lasting up to 24 hours, and without compromise of other neurologic functions. Typically, it occurs in individuals aged 50-80 years, with a decreased incidence in younger and older populations. There may be many causes of TGA. Hippocampal ischemia also contributes to the cause of TGA. In this case report, a 67-year-old woman who presented with TGA clinical features accompanied by right hippocampal diffusion-weighted imaging hyperintensity is presented.
