Mind blowing sex

CNN:

It was either mind-blowing or completely forgettable. Either way, Alice doesn't remember.

One August morning, Alice and her husband, Scott, had sex.

That's when things became confusing. Rather than appearing pleased, Alice, 59, seemed disoriented.

As they lay in bed, Scott (the couple asked that their last name not be used) flicked on the television, which was showing the Olympics. This perplexed Alice. "Is there an Olympics?" she asked. This was during the Michael Phelps mania, when the swimmer seemed to be everywhere.

"Are you sure there is an Olympics?" Alice asked again.

Scott recalled, "I saw that something was wrong, so I asked her, 'OK what day is it?' "

Alice appeared even more perplexed.

"Who's our president?" he quizzed.

"Bill Clinton," she answered. This was 2008.

Scott darted out of bed and called 911. The paramedics suspected a stroke and rushed the befuddled Alice to the emergency room.

For decades, doctors described cases of a rare neurological condition that usually occurred in patients over age 50. Neurologists noted that patients knew their identities, but couldn't retain recent memory, where they were and how they got there. They showed no other symptoms.

Sex is one of the major triggers for the baffling medical condition called transient global amnesia in which patients lose their ability to retain immediate memory.

TGA usually occurs after the person engages in strenuous activity -- such as having sex, vigorously exercising, suddenly immersing into icy or hot water, straining to dig a stuck car or even bumping the head.

I have heard people talk about mind blowing sex for a long time, but I had no idea it could trigger amnesia.
