Transient global amnesia
Transient global amnesia refers to a passing episode of short-term memory loss without other signs or symptoms of neurological impairment . In transient global amnesia (TGA) the individual does not lose consciousness but does lose the ability to form new lasting memories. It does not affect the person's motor function , but the person may be disoriented to place and time, may recognize that something is wrong, and may become distressed at this realization .
