The Clinical Concurrence of Migraine and Transient Global Amnesia: Case Series of ‘Migramnesia’?
Abstract
Complaint of transient impairment or loss of memory as an attendant feature in some migraine attacks has long been recognised. In some cases, migraine may be a trigger or precipitating factor for the syndrome of transient global amnesia (TGA); however, the exact frequency of this concurrence is unknown. Here, the authors present three cases of TGA in the context of migraine headache, consider possible reasons why this concurrence might be under‐recognised, review possible shared pathogenetic mechanisms and suggest a new terminology—‘migramnesia’—which may encourage clinicians to address the possible significance of migraine in the context of an episode of TGA.
