What is the difference between a TIA and transient global amnesia?

While transient decrease in blood flow (a transient ischemic attack or “TIA”) to the hippocampus can mimic TGA, TGA usually lasts longer than a typical transient ischemic attack. 1 There is no clear relationship between stroke risk factors and TGA. Some studies suggest that migraines are associated with TGA.

Can transient global amnesia be caused by stress?
