TEA and transient global amnesia (TGA) are two distinct conditions that share similarities regarding memory impairment. TEA relates to epilepsy, particularly in the temporal lobe, while there is a lack of full understanding of what causes TGA.
Additionally, doctors characterize TEA by recurrent amnesic episodes, often involving autobiographical memory. In contrast, TGA is typically a single, self-limiting episode of profound anterograde amnesia. Anterograde amnesia refers to memory loss where a person cannot form new memories.
