Stroke is a condition caused by lack of blood flow to the brain or hemorrhage or bleeding in the brain. Although strokes are the third leading cause of death in the US, most strokes are not fatal. Symptoms of stroke include weakness, numbness, or inability to move an arm or leg; sudden and intense headache; severe dizziness or loss of coordination and balance; difficulty with speaking or understanding; and blurred or decreased vision in one or both eyes. People with stroke may also have seizures, vomiting, drooling, and difficulty swallowing. People experiencing symptoms suggestive of having suffered a stroke require immediate emergency care and medical attention. Post-stroke symptoms may include coma, reversible or irreversible paralysis, speech problems, dementia, and visual disturbances.
Preventing and treating conditions such as hypertension, diabetes, high cholesterol or homocysteine levels, and atherosclerosis significantly reduces the risk of developing strokes. Stroke prevention encompasses healthy lifestyle and dietary changes and nutritional supplementation to support optimal heart function and blood sugar regulation.
