There are two main types of stroke. The most common is when a clot blocks an artery that carries blood to the brain. This is caused by a Cerebral Thrombosis or Cerebral Embolism. The second most common stroke is a Bleed. This is when a Blood Vessel breaks in the brain, also called a Hemorrhagic Stroke. The first signs of a stroke are numbness, slurred speech, weakness, paralysis on one side of the body, blurred vision or sudden loss of vision, drooping arm or leg, dropped face or dribbling mouth, unsteadiness, confusion speaking or understanding speech.
