Transient global amnesia

[Britney]

Transient global amnesia is anterograde and usually retrograde amnesia that begins suddenly and lasts up to 24 hours. Diagnosis is primarily clinical but includes laboratory tests and CT, MRI, or both. The amnesia typically remits spontaneously but may recur. There is no specific treatment, but underlying abnormalities are corrected.
Most (75%) cases of transient global amnesia occur in people aged 50 to 70; this disorder rarely occurs in people lt; 40.
