Stroke

Monday, May 12, 2014

Stroke is a disease that affects the arteries leading to and within the brain. It is the fourth-leading cause of death and a leading cause of disability in the United States. Dr. Edward Hill tells us more about stroke in todays 60 Second Housecall.

Dr. Hill:

A stroke occurs when blood flow to the brain is interrupted. When a stroke occurs, brain cells in the immediate area begin to die because they stop getting the oxygen and nutrients they need to live.

There are two major kinds of stroke. The first, called an ischemic stroke, is caused by a blood clot that blocks or plugs a blood vessel or artery in the brain. About 87 percent of all strokes are ischemic. Hemorrhagic strokes are caused by a blood vessel in the brain that breaks and bleeds into the brain.

The effects of a stroke can include paralysis, problems with thinking, speaking and emotions.

Treatments are available that can greatly reduce the damage caused by a stroke. Getting treatment within 60 minutes can prevent disability. With any stroke symptoms, get to an emergency room as soon as possible.

The good news is that strokes are preventable. It starts with managing key risk factors, including high blood pressure, cigarette smoking, atrial fibrillation and physical inactivity.
