Stroke risk generally increases with age, but a stroke can happen to adults of any age. The most important warning signs usually appear suddenly, and recognizing them quickly can make a critical difference. The first five signs are sudden numbness or weakness of the face, arm, or leg—especially on one side; confusion or difficulty speaking; trouble understanding speech; sudden vision problems in one or both eyes; and sudden difficulty walking, dizziness, or loss of balance or coordination. A sixth warning sign is a sudden, severe headache with no known cause. These are the classic symptoms emphasized by the CDC, and they should never be dismissed simply because they disappear after a few minutes. A temporary episode can represent a transient ischemic attack (TIA), sometimes called a “mini-stroke,” which also requires urgent medical evaluation.
Four additional symptoms that can accompany a stroke include sudden facial drooping, sudden trouble swallowing, sudden loss of coordination, and sudden severe weakness that makes ordinary movement difficult. Some people may experience only one or two symptoms, while others develop several at the same time. The key word is sudden. Stroke affects the brain’s blood supply, and rapid treatment can reduce the risk of permanent brain injury and disability. If you suspect a stroke, do not wait to see whether symptoms improve, do not drive the person yourself if emergency medical services are available, and note the time when symptoms first appeared. The CDC’s stroke-awareness guidance emphasizes acting immediately when symptoms occur rather than delaying treatment.
Knowing the warning signs is only part of prevention. Important stroke risk factors include high blood pressure, diabetes, high cholesterol, smoking, heart disease, obesity, and older age. Many of these risks can be reduced through appropriate medical care, physical activity, a nutritious diet, avoiding tobacco, controlling blood pressure and cholesterol, and taking prescribed medicines as directed. If you or someone nearby develops sudden facial weakness, arm weakness, speech difficulty, vision changes, severe unexplained headache, or trouble walking, treat it as a medical emergency and seek emergency medical help immediately.
