Hippocampal cavities are not associated with cognitive impairment in transient global amnesia

Background: Hippocampal sulcal cavities (HSC) have been speculated to contribute to a higher vulnerability of memory pathways and might be a possible etiological factor in transient global amnesia (TGA). Therefore, we evaluated the influence of HSC on cognitive long-term outcome in TGA-patients. Methods: Fourteen otherwise healthy patients with the clinical syndrome of TGA in their history underwent a high-resolution magnetic resolution imaging...
