An aneurysm can increase in size, causing the artery wall to weaken. Cerebral aneurysm: This is a bulge in the wall of a blood vessel in the brain.Cerebral cavernous malformation: This is when small blood vessels called capillaries collect in the brain, become enlarged and misshapen, and may affect blood flow.Risk factors for intracerebral hemorrhage include blood vessel malformations such as: cerebral amyloid angiopathy, in which proteins collect in the blood vessels in the brain, leading to damage and risk of tears.excess weight around the waist and abdomen.use of recreational drugs such as cocaine.use of blood-thinning medication, such as warfarin (Coumadin).
certain medical conditions, such as a bleeding disorder or sickle cell disease.history of heart disease, cardiovascular disease, or stroke.high levels of low-density lipoprotein (LDL) cholesterol.The following conditions, medical histories, and habits may be associated with a higher risk of stroke: In a subarachnoid hemorrhage, bleeding occurs between the brain and the membranes that cover it. In this type, bleeding occurs inside the brain. An intracerebral hemorrhage is the most common type. There are different types of hemorrhagic stroke. Researchers estimate that about 13% of stroke cases are hemorrhagic strokes. What percentage of strokes are hemorrhagic? Other common causes of hemorrhagic stroke include brain tumors, tumors that metastasize to the brain, and severe infections in the brain. It can happen anywhere from a few days to 2 weeks after an ischemic stroke. There is an especially high risk of a hemorrhagic stroke after a large ischemic stroke with extensive brain damage and tissue swelling. This damages brain tissue, making it frail and prone to bleeding. The damage from a hemorrhagic stroke can result from pressure caused by bleeding, edema, or a lack of blood supply.īrain tissue can bleed after an ischemic stroke, which is a stroke caused by a blocked blood supply. This can happen when a blood vessel in the brain bursts or when brain tissue starts to bleed.
