Sex Really Can Be 'Mind-Blowing'

LiveScience takes note of what may be the weirdest possible consequence of sex: amnesia. A medical journal recounts the recent case of a 54-year-old woman who showed up at the ER complaining that she barely remembered a thing from the past 24 hours: Diagnosis: transient global amnesia, triggered by the sex she had with hubby. The good news is that, as with most such cases, the condition cleared up in short order.

"It causes a lot of alarm, but this is not a stroke or an event that causes damage to the brain," says one neurologist. "It's almost always very benign." The condition most often strikes people in their 50s and 60s, and it can be triggered by strenuous activity other than sex. One theory: When a person raises pressure inside their abdomens, it affects blood flow in the jugular vein, which carries blood from the brain down to the heart. (More sex stories.)
