![]() In 2019, reports emerged from China of a woman who had temporarily lost a decade's worth of memories after straining on the toilet. More rarely, episodes of TGA have also been triggered by strenuous exercise, sudden immersion in cold or hot water and sexual intercourse - meaning the man's post-sex memory lapse is not entirely unheard of. Psychological factors, such as anxiety, may also make TGA more likely in some individuals. Researchers have also suggested that a lack of sufficient blood flow - ischemia - or oxygen flow to the brain could be associated with the condition. While the exact cause of TGA is unknown, there is a link between sudden memory loss and a history of migraines. "Upon arrival at the emergency department, his neurological examination was completely normal." However, upon presenting at A&E, no other neurological symptoms were detected. The report added that the man had repetitively questioned his wife and daughter about the events of that morning and the previous day. ![]() "His autobiographical memory remained intact, but he had no memory of that morning or the celebrations the night before." ![]() "He had, in fact, celebrated his wedding anniversary with his wife and family on the previous day. "After seeing the date on his phone, he became distressed that he had forgotten his wedding anniversary the day before. ![]() "On the afternoon of presentation, he had engaged in sexual intercourse 10 minutes before the onset of memory disturbance," the report said. The paper, titled ' Recurrent Postcoital Transient Global Amnesia Associated with Diffusion Restriction within the Left Hippocampus', explained that the man, who was taken to A&E after experiencing the sudden episode of memory loss, had also suffered a similar incident seven years prior. Medics at the Department of Neurology at University Hospital Limerick in Ireland said the case study demonstrated that sex can be a trigger for TGA. During an episode of TGA, the person's recall of recent events simply vanishes. TGA is a sudden, temporary episode of memory loss that can't be attributed to a more common neurological condition, such as epilepsy or stroke. ![]()
