Document Summary
Key points: stroke, or cerebro-vascular accident (the medical term for stroke) occurs when there is ischemia (inadequate blood flow) to a part of the brain or hemorrhage into the brain that results in death of brain cells. Functions such as movement, sensation, or emotions that were controlled by the affected area of the brain are lost or impaired. Risk factors for stroke: the most effective way to decrease the burden and incidence of stroke is prevention. Nonmodifiable risk factors include age, gender, ethnicity and race, family history and heredity, and low birth rate: hypertension is the single most important modifiable risk factor. Other modifiable risk factors include heart disease, diabetes mellitus, increased serum cholesterol, smoking, excessive alcohol consumption, obesity, physical inactivity, poor diet, and drug abuse: atherosclerosis (hardening and thickening of arteries) is a major cause of stroke. It can lead to thrombus formation and contribute to emboli.
