Stroke

A stroke occurs when a major artery in the brain is blocked. This blockage is caused by a blood clot, a compression or constriction of a blood vessel, or a rupture of the vessel accompanied by bleeding. A pouch-like expansion of the blood vessel, called an aneurysm, may weaken and then burst during high blood pressure. When the blood supply to a small part of the brain is interrupted, the function of the area is lost. One-sided paralysis (hemiplegia) occur on the other side of the body, not the side that brain is affected. A blood clot can be removed from a clogged artery or can bypass it with an artificial blood vessel made of plastic. Physiotherapy can help stroke patients recover their lost functions.
