Stroke Rates Among Younger Adults Have Increased, Raising Prevention Concerns

Stroke occurs when blood flow to part of the brain is blocked or when a blood vessel ruptures. It can lead to lasting disability, speech difficulties, problems with movement, cognitive changes or death. Although stroke risk generally increases with age, younger adults can also experience strokes. Important risk factors include high blood pressure, diabetes, smoking, abnormal cholesterol, some heart conditions, physical inactivity and certain underlying vascular or clotting disorders. The reasons for rising rates in younger adults may differ between populations and require careful investigation; the reported trend should not be assumed to have a single cause. Prevention includes checking blood pressure, managing diabetes and cholesterol, avoiding tobacco, maintaining regular physical activity and obtaining appropriate medical care for relevant conditions. People should not assume they are too young to have a stroke. Sudden facial drooping, weakness or numbness—especially on one side—difficulty speaking, sudden vision loss, loss of balance or a severe unexplained headache can indicate a medical emergency. Emergency services should be contacted immediately, even if the symptoms improve.
