Cerebral hemisphere strokes, also known as cerebrovascular accidents (CVAs), occur when there is a disruption in blood flow to a part of the brain, leading to damage to the cerebral hemispheres. These strokes can have various causes, symptoms, diagnostic tests, treatments, and preventive measures. Understanding these aspects is crucial for prompt recognition and management.
Types of Cerebral Hemisphere Strokes:
