Long-term prognosis in transient global amnesia
P. A. Nausieda and I. V. Sherman
Transient global amnesia (TGA) is generally believed to be a transient
ischemic attack affecting short-term memory centers. 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%). Transient global amnesia would
appear to carry a more benign prognosis than classical transient ischemic
attacks.
