Transient global amnesia ( TGA) is a neurological disorder whose key defining characteristic is a temporary but almost total disruption of short-term memory with a range of problems accessing older memories. A person in a state of TGA exhibits no other signs of impaired cognitive functioning but recalls only the last few moments of ...
A person experiencing a TEA episode has very little short-term memory, so that there is profound difficulty remembering events in the past few minutes (anterograde amnesia), or of events in the hours before the onset of the attack, and even memories of important events in recent years may not be accessible during the amnestic event (retrograde amnesia).

Transient epileptic amnesia is a rare and unrecognized form of temporal lobe epilepsy, which is typically an episodic isolated memory loss. It has been recognized as a treatment-responsive syndrome congenial to anti-epileptic drugs.

Dissociative amnesia or psychogenic amnesia is a dissociative disorder "characterized by retrospectively reported memory gaps. These gaps involve an inability to recall personal information, usually of a traumatic or stressful nature." [ 1] In a change from the DSM-IV to the DSM-5, dissociative fugue is now subsumed under dissociative amnesia. [ 2]
Electroconvulsive therapy ( ECT) or electroshock therapy ( EST) is a psychiatric treatment where a generalized seizure (without muscular convulsions) is electrically induced to manage refractory mental disorders. [ 1] Typically, 70 to 120 volts are applied externally to the patient's head, resulting in approximately 800 milliamperes of direct ...
In neurology, retrograde amnesia ( RA) is the inability to access memories or information from before an injury or disease occurred. [ 1] RA differs from a similar condition called anterograde amnesia (AA), which is the inability to form new memories following injury or disease onset. [ 2] Although an individual can have both RA and AA at the ...
