A stroke is a reduction in blood supply to the brain due to a blockage or bleeding in the brain. Rapid treatment—within three hours of the first symptom—is crucial. Stroke symptoms come on suddenly and include trouble speaking; confusion; weakness, numbness, or paralysis on one side of the face or body; vision problems; severe headache; or trouble with walking or balance.
