A brain hemorrhage is a type of stroke that occurs when blood leaks into brain tissue and causes damage to the brain. When blood from the injury irritates brain tissue, it causes swelling, and blood collects into a mass called a hematoma. This increases pressure on surrounding tissue, eventually killing brain cells and causing a brain blood vessel to rupture.

If patients with cerebral hemorrhage are treated promptly, the size of the hematoma will not increase and complications will be reduced. Some patients with cerebral hemorrhage can recover and walk after treatment.

Stroke is common in people with diseases such as high blood pressure, diabetes, lipid disorders, obesity. The disease occurs due to atherosclerosis, causing the lumen of the blood vessels to narrow, easily forming blood clots causing blockage.
