Glossary / Lexicon

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.
