Hoping you can tell me, is transient ischemic attack considered an acute stroke?

Yes: But is has no permanent sequelae. It can be a harbinger or worse tias or strokes to come. Get checked for carotid disease or cardiac defects such as pfo.

Yes: Yes indeed. When neurologic symptoms start suddenly we always considered it an acute stroke. If they pass within few minutes or hours completely, they get labeled tia. If they stay and there are changes on mri, then we call it a stroke. But for all practical purposes, TIA is considered an acute stroke at the onset.
