Orthostatic transient ischemic attacks: a symptom of large vessel occlusion

E R Somerville. Stroke. 1984 Nov-Dec.

Abstract

Orthostatic transient ischemic attacks (TIA) are very much rarer than orthostatic generalized cerebral ischemia (syncope). A case is described and previous reports reviewed. Orthostatic TIA appears to occur only with large vessel occlusion. In these patients, collateral blood supply is marginal and unable to support normal postural autoregulation.
