Transient Global Amnesia
Introduction
Transient global amnesia is characterized by sudden-onset anterograde and retrograde amnesia that typically lasts up to 24 hours. Diagnosis is primarily clinical, but laboratory and imaging studies are done to exclude other disorders. The amnesia typically remits spontaneously but may recur. There is no specific treatment unless an underlying condition is present. The annual incidence of transient global amnesia is between 3.4 and 10.4/100 000. Most cases of transient global amnesia occur in people aged 50 to 70; this disorder rarely occurs in people < 50. It affects men slightly more often than women ( Reference ).
