Transient Global Amnesia

Transient global amnesia (TGA) is a brief but near complete loss of short-term memory, accompanied by a range of difficulties accessing long-term memories, despite no other signs or symptoms of neurological impairment being present. Episodes can last anywhere from 20 minutes to 20 hours, with a fairly rapid onset, typically affecting people between the ages of 65 and 75. Though TGA does not cause one to lose consciousness or any motor functions, individuals experiencing it may become disoriented and distressed, although they otherwise appear mentally alert.
