A cerebrovascular accident more commonly known as a stroke or brain attack is the term used to describe the sudden death of brain cells in a localized area due to inadequate blood flow. In order to woke the brain needs a constant supply of

This accumulation narrows, hardens, and roughens the inside surface of the arteries. Turbulent blood flow around deposits of plaques trigger clot development.
Ischemic Strokes

A Ischemic stroke occurs when a blood clot blocks an artery either in the brain itself or in the neck. These blockages stem from three conditions; the formation of a clot within a blood vessel of the brain or neck, called Thrombotic; The movement of a clot from another part of the body such as the heart to the neck or brain called embolism; or a severe narrowing of an artery in or leading to the brain, called stenosis.

Thrombotic stroke occurs when a blood clot forms in one of the cerebral arteries that stays attached to the artery wall until it grows large enough to block blood flow.Cerebral Thrombus occurs most often at night, or early in the morning. In most instancies the underlying cause is Atherosclerosis. Cerebral thrombosis is often preceded by a transient ischemic attack, or TIA, sometimes called a ¡§mini-stroke.¡¨ In a TIA, blood flow is temporarily interrupted, causing short lived stroke like symptoms.This kind of Ischemic stroke accounts for 60% of a stroke cases.

Embolic stroke is another common form of Ischemic stroke. It can occur when a clot, or small piece of plaque formed elsewhere in the circulatory system breaks free.This free roaming clot travels through the bloodstream until it reaches vessels too small to let
