Stroke is one of the most common causes of disability in older adults. It remains a common cause of death and permanent functional limitation in individuals who are older than 80 years. Approximately 50% of all strokes occur in people over the age of 75, and 30% in those over 85. Top priorities in primary stroke prevention include the treatment of hypertension, anticoagulation for patients with atrial fibrillation, and lifestyle modifications such as smoking cessation.
