What is a Stroke?

Cerebrovascular accident (CVA) or stroke occurs when a clot blocks an artery (a blood vessel that carries blood from the heart to the body) or a blood vessel (a tube that passes through the blood to the body) breaks, interrupting blood flow to a region of the brain. If any of these things happens, brain cells begin to die and brain damage occurs.

When brain cells die during a stroke, the capacity of the region of the brain are lost. These abilities include speech, movement and memory. How a stroke patient is affected depends on where the stroke occurs in the brain and to what Moai 3: Trade Mission Collector's Edition Game Download Free extent the brain is damaged.

What causes a stroke?

The artery blockage in the brain by a blood clot (is called thrombus) is the main cause of stroke. Moai 3: Trade Mission Collector's Edition Game Download Free The part of the brain that is full by the clotted blood vessel is then deprived of oxygen and blood. As a result of the deprived oxygen and blood, the cells of that part of the brain die. In general, a clot in Moai 3: Trade Mission Collector's Edition small blood vessels of the brain has been reduced 5 Reasons Why You Must Study Japanese by several factors, including:

1. High blood pressure (hypertension),

2. High Moai 3: Trade Mission Collector's Edition cholesterol,

3. Diabetes

4. Smoking

What Are the Types of Stroke?

Embolic stroke

Embolic stroke may be occur when a blood clot or a piece Moai 3: Trade Mission Collector's Edition of plaque (deposits of cholesterol and calcium in the inner wall of the arteries Kindle Upgrade of the heart or unleashed), travels through open arteries, and present in an artery in the brain. Moai 3: Trade Mission Collector's Edition If this happens, the flow of oxygen through blood to the brain is blocked and stroke occurs. This type of attack is called embolism. For example, a blood clot might originally in the abdomen after irregular heart rhythm, form, as in cases of atrial Moai 3: Trade Mission Collector's Edition Game Download Free fibrillation. Generally, these clots remain attached to the inner wall of our heart, but sometimes it can break off, travel through the bloodstream, forming a plug (embolism) in an artery in the brain and cause stroke. An embolism can also come from one of the great arteries (eg carotid artery, a major artery of the neck providing blood to the brain), then downstream to clog a small artery in our brain.

Cerebral hemorrhage

A cerebral hemorrhage is another type of stroke, which occurs when a blood vessel in the brain rupture and bleeds into the surrounding tissue of our brain. A cerebral hemorrhage (bleeding Moai 3: Trade Mission Collector's Edition inside the brain) can cause stroke by the extraction of blood and oxygen to parts of the brain.

Vasculitis

Another rare cause of stroke is vasculitis, a disease in which inflammation of Windshield Repair and Auto Gl[censored] Replacement - What to Do When a Hail Storm Has Destro[censored] Your Glass blood vessels.

Migraine headache:

It seems a very small increase in the incidence of stroke in patients with migraine. The mechanism for the treatment of migraine or vascular Spanish Toy Manufacturers to Look at the Debt Crisis in Europe headaches includes constriction of blood vessels in the brain. Some episodes of migraine can mimic the same stroke with loss of function on one side or edge of vision or speech problems. In general, the symptoms such as headache disappear.
