Definition & Operational Usage
A cerebrovascular accident (CVA), commonly referred to as a stroke, occurs when blood supply to a specific region of the brain is disrupted, resulting in potential brain cell necrosis. The two primary classifications are ischemic strokes, which arise from vascular occlusions, and hemorrhagic strokes, which are due to vascular rupture. Not to be confused with transient ischemic attacks (TIAs), which are temporary episodes of neurological dysfunction, timely differentiation and intervention are critical for optimizing patient outcomes, particularly within the framework of the Incident Command System (ICS).
