A stroke is the rapid loss of brain function due to an insufficient supply of blood to the brain. There are a number of factors that can disturb the blood supply to the brain, including the blockage of blood flow in the arteries of the brain, or the narrowing or clogging of one or more arteries due to the formation of blood clots or a burst blood vessel in the brain. It is a medical emergency that can cause permanent neurological disabilities, and at times death. People with high blood pressure are at a higher risk of suffering from a stroke.

A seizure is a medical condition that occurs due to a sudden increase in the activity of neurons in the brain, and is usually experienced by the patients of epilepsy. The term seizure is often used interchangeably with “convulsion”, a medical condition in which a person’s body suddenly starts shaking rapidly and uncontrollably. During a convulsion attack, the muscles of the patient's body contract and relax repeatedly, a condition which is very much similar to a seizure attack.
