Numbness. Confusion. Trouble seeing or walking. These are all signs of stroke, one of the leading causes of death and serious long-term disabilities.
An online quiz from the National Institute of Neurological Disorders and Stroke (NINDS) can teach you more about signs, symptoms, and risk factors of stroke.
The quiz is part of NINDS' Know Stroke initiative, which has information in English and Spanish. Other resources include links to stroke clinical trials, a quick video, and toolkits for teachers.
