Clinicians rely on a systematic evaluation to identify cerebrovascular accidents, distinguishing between ischemic and hemorrhagic events with speed and accuracy. While not a diagnostic tool for physicians, FAST significantly reduces the time from symptom onset to hospital arrival, which is crucial for interventions like thrombolysis.

A detailed history regarding headache, consciousness, and progression of symptoms helps clinicians differentiate a true vascular event from these critical mimics, preventing inappropriate management. Key historical elements include the onset of symptoms, which is often abrupt, and risk factors such as hypertension, atrial fibrillation, or diabetes.
Initial Clinical Assessment and History A thorough medical history and rapid neurological exam are the foundation of any CVA medical diagnosis. Hemorrhagic strokes involve bleeding within the brain tissue or subarachnoid space, typically from a ruptured aneurysm or hypertensive vessel.

Ischemic strokes, accounting for the majority of cases, result from a blocked artery, often due to thrombosis or embolism. A non-contrast CT scan of the head is typically the first-line imaging, rapidly ruling out hemorrhage.
