Transient global amnesia (TGA) is a rare and fascinating acute neurological disorder. It is characterized by idiopathic sudden onset anterograde memory loss that resolves within 24 hours of onset and results in no long-term sequelae. The gold standard diagnostic testing for this disorder are clinical criteria. Common emergency department investigations such as bloodwork and computed tomography scans are unremarkable. This paper reviews the yield of diffusion-weighted magnetic resonance imaging (DW-MRI) in the acute setting for the diagnosis of TGA.
