A brain stroke is the second leading cause of death and is responsible for 4.5 million deaths per year.  Stroke is also the number 3 cause of death in the Unites states right behind heart disease and cancer and affects more than 3 quarters of a million Americans annually.

A stroke can be described as a sudden fit that affects consciousness, movement and sensation, which is the end result of a blockage or ruptured blood vessel in the brain and can last for up to 24 hours.   A stroke occurs when the blood supply to part of the brain is interrupted or when a blood vessel in the brain burst causing blood to spill out into the surrounding brain cells.  Brain cells die when they do not receive nutrients and blood from the blood or when there is sudden bleeding in and around the brain.   The most common signs of stroke are a sudden numbness or weakness in the face, legs or arm and especially on one side of the body.  Those suffering from a stroke will also experience trouble walking, experience dizziness or loss of balance or coordination, confusion, trouble with speech or a severe headache with no known cause.

There are two main types of stroke that are named hemorrhagic and ischemic.   The ischemic type happens when there is a lack of nutrient and oxygen rich blood to a part of the brain and this causes that part of the brain to die.  This lack of flow happens when there is a severely narrowed or blocked artery in the brain or neck and makes up around 90 % of all stroke cases.

The second type of stroke is the hemorrhagic stroke and happens when there is bleeding in the brain from a broken blood vessel. There are several causes as to why a blood vessel in the brain may become blocked or narrowed such as an embolism or thrombosis.  An embolism happens when a blood clot from another part of the body such as the heart travels through the blood and into the brain or neck and can become wedged in a smaller brain artery.  This clot or tissue is called an embolism and often form in the heart.   There are many conditions that can increase a person chances for developing an embolism and the most common ones can include atrial fibrillation, sick syndrome and irregular heart rhythms which can cause pool blood flow which allow harmful clots to form and are most likely to form in those with heart valve diseases like mitral valve prolapse, sickle cell disease, rheumatic heart disease and endocarditis. Thrombosis happens when a blood clot form within the blood vessel and causes the blood vessel to become narrowed or even blocked and in most cases even plaque buildup occurs which causes stenosis.

If you have suffered form a stroke it does not mean that it is the end of your normal life. As long as you follow a good and strict diet, get plenty of exercise  and rest you will be able to live past  a stroke and still enjoy a good and healthy life.
