Vertebrobasilar events sometimes present as acute confusional states or coma as opposed to discrete focal syndromes. Presumably, cognitive changes reflect thalamic, mesial temporal, and mesencephalic involvement in most cases. Acute encephalopathy is a rare complication of GCA and is a poor prognostic sign. Many patients with this complication progress to coma and die.
