What is a stroke?

A stroke is the death of brain cells caused by a blood clot or a ruptured blood vessel in the brain.

Since the brain is the control center of the body, the death of those brain cells results in the loss of all the abilities that were controlled by that part of the brain.

A stroke in your brain’s speech center can knock out the ability to read, write, or even talk. A stroke in a coordination center can affect your walking or hand coordination. A stroke in the front part of the brain may change your personality.

Since the brain has two sides, a stroke can cripple one side of your body, while the other side remains perfectly normal.

If a stroke is caused by a large blood clot or serious bleeding in the brain, symptoms can occur within seconds.

However, if an artery is just narrow or partially blocked, stroke symptoms may develop over several hours, giving you and the Emergency Room team time to react and sometimes reverse the effects of the stroke.
