Ultra-high field magnetic resonance imaging of the hippocampus after transient global amnesia


  • Hippocampal lesions detected by diffusion-weighted imaging (DWI) during the acute phase of transient global amnesia (TGA) do not result in any chronic hippocampal defects.

Why this matters

    The long-term course of hippocampal lesions detected by DWI after TGA has not been
    well-studied; as such, the pathophysiology of these lesions in TGA has remained unknown.
