Journalist Katie Couric was diagnosed with transient global amnesia after a medical episode on Saturday, June 27, in Aspen, Colorado.
The 69-year-old media personality experienced a seven-hour block of temporary memory loss during her visit to the Aspen Ideas Festival.

According to essays published by Couric and her husband, John Molner, on her Substack newsletter, the episode began around noon after she completed two panel presentations.
While participating normally in the festival, she later retained no memory of the afternoon or the contents of her speeches.
Hospital staff initially initiated a stroke protocol at Aspen Valley Hospital when Couric failed to correctly identify the current year, the sitting president, or the names of recent family members.
An MRI subsequently cleared Couric of any signs of a stroke, leading physicians to confirm the amnesia diagnosis.
"This was a freaky occurrence, it could have been much more serious," explained Couric, noting that several hours of her day will always remain missing.
Her husband observed that while Couric appeared weak and dizzy after her final presentation, she could initially answer basic questions.
Her condition deteriorated shortly after, prompting continuous repetition of identical questions regarding her whereabouts and actions.

"She reintroduced herself to the nurses every time they came into the room.
I felt like Bill Murray in 'Groundhog Day' as she repeatedly asked me the same questions," wrote Molner.
