Stroke Symptoms & Signs
Medical Author: Melissa Conrad Stöppler, MD
The symptoms of a stroke vary depending upon the area of the brain affected by a lack of oxygen. All strokes involve symptoms that relate to impairment of nerve function. The symptoms typically arise suddenly and most commonly occur on one side of the body. Symptoms and signs of stroke can include numbness, weakness, tingling, or vision loss or changes. Confusion, changes in the level of consciousness, trouble speaking, trouble understanding speech, vertigo, and balance problems are other common symptoms. Headache, nausea, and vomiting sometimes accompany a stroke, particularly when the stroke involves bleeding inside the brain.
