Question

Quizplus · Accepted Answer

Transient global amnesia (TGA) is a temporary condition characterized by sudden onset of memory loss, usually lasting for several hours. The cause of TGA is believed to be linked to temporary disruption of blood flow to the hippocampus, a brain region crucial for memory formation and retrieval. Studies have shown that TGA patients exhibited abnormalities in hippocampal function, such as reduced blood flow and metabolic activity, but no evidence of permanent damage. Thus, temporary disruption of the hippocampus is the most likely cause of TGA.
