An Overview of Stroke - Part 1

December 21, 2011

Although stroke and heart disease do not affect the same part of your body, they share many similar risk factors. If you are suffering from heart disease, there is a higher chance that you will develop stroke. Stroke is a leading cause of disability and death in the United States. It is a condition that affects the arteries that are within or connected to your brain.

Stroke results from the blockage or bursting of a blood vessel that transports oxygen and nutrients to your brain. Stroke prevents your brain from getting the oxygenated blood it needs to function properly, and therefore, causes it to deteriorate.

Learn the different types of strokeStroke can come in three different forms, namely, ischemic, hemorrhagic, and transient ischemic. The most common type of stroke is ischemic stroke, which is caused by clots that obstruct a blood vessel leading to your brain. Transient ischemic attack, or TIA, is a milder version of ischemic stroke, and it results from a temporary clot. A hemorrhagic stroke occurs when a blood vessel that serves the brain is ruptured.

The effects of stroke vary from one person to another, and they are determined by the location of the blocked arteries and the amount of brain tissue affected. Stroke can occur in the right or left side of your brain, and it will cause neurological complications on the opposite side of your body. If it affects the right side of your brain, you may experience paralysis on the left side of your body, memory loss, vision problems, and quick and inquisitive behavioral style. If it occurs in the left side, possible effects include paralysis on the right side of your body, memory loss, speech and language problems, and slow and cautious behavioral style. A stroke can also affect your brain stem, and it may cause complications on both sides of your body, or leave you unable to speak or paralyzed from neck down.

If you are experiencing any of the symptoms of stroke, you should consult a doctor immediately.
