Abstract

Vertebral artery dissection is one of the most common causes of stroke in young adults. The course of the vertebral artery dissection is usually benign, and pure transient amnesia as an initial symptom has been rarely reported. We describe a patient with vertebral artery dissection who presented with acute transient amnesia, and review the medical literatures about the pathophysiological mechanism of transient global amenesia (TGA). This case could be a one of evidence which supports the cerebrovascular mechanism of TGA.
