Sex can trigger rare temporary memory loss, experts say

In rare instances, sexual activity can trigger a peculiar and temporary memory disorder known as transient global amnesia (TGA). This condition, though uncommon, highlights the brain's complex reactions to stress, exertion, and intense emotions.

According to a study published in The Lancet, TGA is characterized by a sudden, temporary inability to form new memories. Individuals experiencing TGA remain conscious and can communicate, but they lose track of recent events and cannot retain new information during the episode. The Mayo Clinic describes it as a sudden onset of confusion accompanied by memory loss, often noticeable to observers.

Researchers have documented cases involving men over 70 who exhibited unusual behavior about 30 minutes after intercourse. One 72-year-old man was found disoriented, even misidentifying the current U.S. president. Despite neurological and MRI scans being normal, the episode resolved on its own, and the man had no recollection of the event. Another case involved a 75-year-old retired doctor who experienced similar disorientation and political misidentification post-intercourse, recovering fully within 15 hours.

While the precise cause of TGA remains elusive, the Mayo Clinic suggests several potential triggers reported by patients. These include sudden exposure to extreme temperatures, intense physical activity, sexual intercourse, medical procedures, minor head injuries, and significant emotional stress. The condition underscores how various physiological and emotional states can uniquely affect cognitive function.
