What are the long term effects of transient global amnesia?

A recent three-year follow-up found a high incidence of subsequent dementia and stroke in patients with TGA. We studied the course (average, 46 months) of 32 patients with TGA and found a low rate of recurrence (12.5%), dementia (6%), or transient ischemic attacks (3%).

How rare is transient global amnesia?

Transient global amnesia (TGA) occurs in approximately 3 to 10 people out of every 100,000.

Can you recover from TGA?
