Hemorrhagic Stroke

A hemorrhagic stroke results from a breakage of blood vessels in the brain.  A cerebral hemorrhage can be caused by a number of conditions affecting the blood vessels.  However, the two most common causes of hemorrhage are high blood pressure and ruptured cerebral aneurysms. In an aneurysm, a weak spot on a blood vessel wall dilates, thus forming a balloon. Aneurysms are usually present at birth, and develop over a number of years.  They do not cause detectable behavioral or motor problems until they become enlarged or rupture.
