Abstract
Cerebral autoregulation and mechanisms of cellular ischemia are crucial concepts for stroke pathophysiology. The effective stroke clinician requires core knowledge of normal brain physiology and blood flow and how these processes are affected during ischemia and hemorrhage. A basic understanding of these concepts will serve you well for the boards and help guide treatment for your patients.
