In a bizarre incident, a 66-year-old Irish man was taken to hospital with short-term dementia after having sex with his wife.
The abnormal phenomenon was analyzed in the May issue of the Irish Medical Journal, published on Wednesday, and doctors explained that gender is the trigger for short-term amnesia – officially known as transient global amnesia (TGA).
The Mayo Clinic defines TGA as “an episode of sudden transient global amnesia that is not caused by common neuropathy, such as epilepsy or stroke.”
In the case of this Irish man, the medical journal reported that he lost his short-term memory within 10 minutes of having sex.
After their sexual intercourse, the man notices the date on his mobile phone and he ‘suddenly gets upset that he forgot his wedding anniversary the day before.’ Although the man had celebrated the special event the previous evening, he had no idea about it.
“He repeatedly questioned his wife and daughter about what happened that morning and the day before,” according to the journal.
Such a rare condition usually affects people between the ages of 50 and 70 and has the potential to “just disappear” from recent events. Some people who are experiencing TGA cannot remember what happened a year ago. Affected people usually regain their memory within a few hours.
In this case, the subject was not compromised with long-term memory, and was able to provide his name, age and other basic background information.
The man had previously experienced TGA in 2015 and this incident also happened shortly after having sex. Fortunately, he later regained his short-term memory.
Realizing he was suffering in another TGA episode, the man went to a local emergency room. There, on a neurological examination, he was found to be “completely normal.” After a while his memory came back.
The author of an article in the Irish Medical Journal, who works in the neurology department at Limerick University Hospital, says that 10 percent of people with TGA have other episodes. The authors add that “TGA precipitation is associated with a number of activities, including physical activity, immersion in cold or hot water, stress, pain, and sexual intercourse.”
Talking about TGA in 2009, one expert said, “It is not enough for a stimulus or deprivation that it permanently hits the brain. It restores the brain. There should be no deficiency other than memory and it should be shortened.”
The incident is horrific for the affected people and their loved ones, but TGA is not considered very serious.
