Stroke can occur at any age, It may occur in children as well. Its severity can be imagined from a fact that Stroke is considered the third leading cause of death in women, and fifth in men. It claims six million deaths and approximately five million disabled lives in a year. Stroke affects nearly 15 million people around the world. In the absence of oxygen, Brain cells start dying and the actions performed by that area are lost, resulting into loss of memory or loss of muscle control. Stroke happens when the flow of blood in arteries is interrupted either by a blockage or by an artery burst. Blood flows in arteries and carries oxygen to the brain for its functioning. Brain needs constant supply of oxygen for proper functioning. It takes signals in the form of odor, taste, pain, voice from various body organs, translates them and prepares a suitable response for them. It is responsible for the functions body performs. When the Heart fails to pump the oxygen rich blood to the Brain, it causes Brain stroke.Д«rain is a major part in the Body. Stroke: It occurs in Brain but is a result of malfunctioning of the Heart. If some thing goes wrong with these electrical impulses, the Heart will not pump the Oxygen rich blood. The Heart muscles contract and relax to pump the blood. Cardiac Arrest: It is associated with the electrical impulses that occurs in the Heart.

Due to this the Heart muscles will not get enough supply of Blood and causes Heart Attack. As a result the Arteries will become narrower and get hardened. Some times the fatty matter starts depositing on the walls of the Arteries and over the time, they form plaque. It takes deoxygenated blood from the body parts and in return gives oxygen rich blood to the Body organs. Heart attack: The main function of the Heart is to pump the Blood. They all are associated with the Heart, but are different. Differential Diagnosis : People are often get confused between the three terms that is Stroke, Cardiac arrest and Heart Attack. Emergency Call a Doctor, if you experience, Confusion Dizziness Blurred Vision Unconsciousness Loss of Balance Numbness in any body part Causes of Brain Stroke Obesity Old age Smoking Diabetes Poor Diet Genetic Factors Arteriosclerosis Lack of Exercise High Blood Pressure Irregular Heart Beat Stress and Depression Formation of Blood clot If not treated properly, it may cause Pain Dysphagia Paralysis Depression Memory loss Hydrocephalus Deep vein thrombosis Difficulty in talking Note: Chain Smokers and women who take contraceptives are more prone to have Stroke. If a Stroke occurs due to a ruptured artery, we call it an hemorrhagic stroke. When a Stroke occurs due to the formation of a blood clot in the Brain, we call it an Ischemic stroke. In this the blood vessels are blocked due to deposition of plaque on their walls. The Stroke may be associated with Atherosclerosis. The death of the tissues in the Brain is termed as Stroke. But, in any case if the blood fails to reach the brain, the tissues begin to die. The blood also carries nutrients that are required by the brain tissues to function properly. Like other body parts, it needs a continuous supply of oxygen rich blood. Brain is a very important part of the Body. The functions of the Brain become impaired after a Stroke. When the Brain cells die because of inadequate supply of oxygen, we call it a Stroke.
