Stroke can occur when a poor blood flow to the brain results in cell death. It is the no.5 cause of death in America and the leading cause of disability. There are two types of stroke: ischemic, caused by narrowing or blockage in the arteries which leads to the brain, and hemorrhagic, caused by reduced blood flow.
When the blood vessel that carries nutrients to the brain is ruptured by a clot or blocked, a part of the brain can’t get blood and oxygen that it needs to function and that consequently leads to cell death. The brain is a complex organ that controls numerous functions in the body, so when a stroke occurs and there is reduced blood flow to a certain part of the brain, some part or parts of the body that the affected part of the brain controls are not able to function properly.
