What exactly happens when a person has a stroke? Is it a heart-attack or to do with the brain? A stroke is sometimes called a "brain attack." Most often, stroke occurs when blood flow to the brain stops because it is blocked by a clot. The brain cells in the immediate area begin to die because they stop getting the oxygen and nutrients they need to function. Although doctors can sometimes intervene to reduce stroke damage, in many cases the brain cells served by these blood vessels become starved and begin to die off. After the stroke, the resulting damage may impair behavior or body functions controlled by the affected parts of the brain. There are two kinds of stroke. The most common kind of stroke, called ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel in the brain. The other kind of stroke, called hemorrhagic stroke, is caused by a blood vessel that breaks and bleeds into the brain. Stroke damage in the brain can affect the entire body - resulting in mild to severe disabilities. These include paralysis, problems with thinking, problems with speaking, and emotional problems. I hope this helps Blot clots in the brain. A stroke, also known as cerebrovascular accident (CVA),[1] is an acute neurological injury in which the blood supply to a part of the brain is interrupted. That is, a stroke involves the sudden loss of neuronal function due to disturbance in cerebral perfusion. This disturbance in perfusion is commonly arterial, but can be venous. It has to do with an injury in the brain as a result of a blood clot or burst vessel cutting off oxygen to the brain. http://en.wikipedia.org/wiki/stroke... It is really a brain attack, whick can cause paralysis on one side, or even both sides of the body. It is the result of a broken blood vessel in the brain and the resultng internal bleeding in the head. Blood Clots in the brain |
