Veteran journalist Katie Couric has disclosed details of a frightening medical episode that occurred last month, during which she temporarily lost the ability to form new memories and could not answer basic questions about her identity and surroundings.
The incident took place on Saturday, June 27, 2026, while Couric was speaking at the Aspen Institute. The 69-year-old broadcaster shared her experience in a Substack post published on Monday, July 6, revealing that she has no recollection of several hours from that day.
"It was Saturday, June 27, 2026. But when I was asked the month, the year, and who was president, I got them wrong," Couric wrote in the post. "I wasn't sure of the month. I thought it was 2024. And I believed Joe Biden was president. Let me explain."
According to Couric, the last memory she retained from that day was traveling to the Aspen Institute with her husband, John Molner. She had delivered remarks on two panels at the institute, but she has no recollection of either presentation.
Molner, 63, contributed to the blog post to provide details his wife could not remember. He explained that an intern approached him following the panels to inform him that Couric was experiencing dizziness and feeling disoriented. The couple proceeded to Aspen Valley Hospital (AVH), where medical staff observed that Couric struggled to answer fundamental questions, including identifying the current month and year, as well as the names of her grandchildren.
"The doctor turned to the nurses and said, 'Initiate stroke protocol,'" Molner recalled in the post.
An MRI scan ultimately ruled out a stroke, though Couric's cognitive impairment intensified during her time in the emergency department. Molner noted that his wife repeatedly introduced herself to nursing staff each time they entered her room, unable to retain any memory of previous interactions.
Medical professionals diagnosed Couric with transient global amnesia (TGA), a condition characterized by sudden confusion and memory loss. According to the Mayo Clinic, the precise cause of TGA remains unknown. Couric was admitted to AVH for observation and began to regain normal cognitive function around 9 p.m. that evening.
"While this was a freaky occurrence, it could have been much more serious," Couric wrote after resuming authorship of the blog post. "So ultimately, I'm relieved — even though several hours of a Saturday in June will always be missing for me."
In a follow-up interview published Tuesday, July 7, by Katie Couric Media, neurologist David Perlmutter, M.D., FACN, provided medical context for the condition. He described TGA as a sudden, temporary inability to form new memories while other cognitive functions remain intact.
"A person is awake, alert, knows who they are, recognizes family members, and can carry on a conversation, but they can't remember what just happened a few minutes ago," Dr. Perlmutter explained to Katie Couric Media. "They often ask the same questions repeatedly, such as, 'Where are we?' or 'How did I get here?' because each answer is quickly forgotten. In fact, this constant repetition of the same question is a symptom I have observed in every patient with this disorder I have ever treated."
Dr. Perlmutter noted that TGA episodes are frequently preceded by sudden physical or emotional stress, including vigorous exercise, heavy lifting, emotional shock, pain, sexual activity, coughing, or straining. In uncommon cases, the condition can be triggered by sudden immersion in cold water.
"Neurologists have recognized for years that diving into very cold water or experiencing an abrupt temperature change can occasionally precipitate an episode of transient global amnesia," Dr. Perlmutter told Katie Couric Media.
The neurologist emphasized the importance of seeking immediate medical attention when TGA symptoms appear, as emergency evaluation is necessary to exclude stroke, seizure, or other serious neurological conditions. He advised caregivers to remain calm and reassure affected individuals, noting that the repetitive questioning characteristic of TGA actually helps confirm the diagnosis.
"Most people quickly return to their normal baseline, with the only lasting effect being that they never remember the hours during which the episode occurred," Dr. Perlmutter explained to Katie Couric Media.
Couric's public disclosure of her medical experience serves to raise awareness of this rare neurological condition and underscores the importance of prompt medical evaluation when sudden memory loss occurs.
