Sex-Induced Brain Fade

Nov 05, 2009 • Health, News

Sorry, honey, I have a headache.

Classic excuse to avoid sex. Total crap, right?

Maybe not. Get this–sex is one of the major triggers for transient global amnesia (TGA), a condition that causes people to lose their ability to retain recent memories. How does sex do this? It produces a sudden change in blood flow, which deprives the hippocampus, the part of the brain that is responsible for short-term memory.

Dr. Louis Caplan, professor of neurology at Harvard Medical School, likens the hippocampus to a tape recorder: if blood flow to the brain is restricted, the hippocampus cannot record new memory.

This condition usually occurs in people over 50. Those with a history of migraines and headaches are more likely to get TGA.
