Platelet Activation in the Cerebral Circulation in Different Subtypes of Ischemic Stroke and Binswanger’s Disease

Abstract

Platelets were activated in the cerebral circulation of patients with stroke even in the chronic phase, which suggests the development of underlying vascular lesions and of thrombogenesis with or without infarction. Platelets were activated mainly within the heart in cases of cardioembolic stroke. An enhanced release reaction secondary to platelet activation was often seen in patients with Binswanger's disease, which indicates that its pathophysiology differs from that of other subtypes of stroke.
