Let’s face it: great sex is great sex; but can it be so good that it blows your mind, literally? Yep, sad but true – this was the case for a 54-year-old female patient brought to the emergency room at Georgetown University Hospital with memory loss that followed a sexual encounter with her husband.

The woman’s episode of transient global amnesia (TGA) is described in the September 2011 issue of the Journal of Emergency Medicine by the two ER doctors who evaluated her and diagnosed her condition; though very rare, these cases of transient or global amnesia (TGA) are quite unforgettable and present themselves in a dramatic fashion. Basically, TGA scrambles your memory circuits and causes memory loss as well as confusion regarding time and space; there haven’t been many documented cases, but doctors have been closely monitoring them, and many are induced by great love making.

Even though the exact cause is not yet known, some studies have shown that the condition has more to do with the neck than with the brain: an insufficiency of the valves in the jugular vein causing blood to possibly seep back upward into the head. However, researchers note that as far as they can tell, this event happens only once in a lifetime, thus discarding your chance of constantly having mind blowing sex.

Having the best sex of your life, and being unable to remember it – possibly ever, now that seems torn from a 90s sitcom, doesn’t it? Either way, kudos to the husband.
