Transient epileptic amnesia (TEA) is a form of epilepsy, probably first described by John Hughlings Jackson in the 19th century. 7 Compared to TGA, episodes of TEA are typically briefer (<1 h), commonly occur on waking, have a high recurrence rate and may be accompanied by other features suggestive of epilepsy such as automatisms or olfactory hallucinations . 2018-07-27 · Transient global amnesia (TGA) has been a well-described phenomenon for more than 40 years.

Transient global amnesia (TGA) is a clinical syndrome marked by the acute onset of profound anterograde amnesia (the inability to form new memories) lasting up to 24 hours in the absence of other neurologic deficits or changes in alertness and cognition. Retrograde amnesia (the loss of pre-existing memories) can also occur. From the last 30-40 years though TGA is a red hot topic on the table for discussion still no evident reason and treatment are available for it.

Both TGA and anterograde amnesia deal with disruptions of short-term memory. However, a TGA episode generally lasts no more than 2 to 8 hours before the patient returns to normal with the ability to form new memories. A patient with anterograde amnesia may not be able to form new memories indefinitely.
