Couric’s Aspen memory blackout diagnosed as transient global amnesia

Journalist Katie Couric experienced a sudden memory lapse at the Aspen Ideas Festival, unable to name the year, president, or panel topics. After medical evaluation ruled out stroke, she was diagnosed with transient global amnesia, a brief, typically reversible episode that can erase recent memories and usually resolves within 24 hours. The exact cause is unknown, though factors like brief disruptions in blood or oxygen flow and other triggers may play a role. Couric recovered and felt back to herself by evening; experts note a recurrence risk exists but episodes are often a one-off event.
