Stroke

Stroke Symptoms and Causes

A stroke, also called a “brain attack,” occurs when blood flow to the brain is disrupted. The main causes of a stroke can be either a blood clot blocking one of the vital blood vessels in the brain (ischemic stroke) or a blood vessel in the brain bursting and spilling blood into the surrounding tissues (hemorrhagic stroke). Symptoms of a stroke usually develop suddenly, without warning, and consist of headaches; changes in alertness, hearing and taste; clumsiness, confusion or loss of memory; difficulty writing or reading; dizziness, numbness or tingling on one side of the body; and vision problems.
