Brain hemorrhage refers to bleeding that occurs either within or around the brain, which can result from an injury or the spontaneous rupture of a blood vessel. There are four main types of brain hemorrhage: subdural, extradural, subarachnoid, and intracerebral. Extradural and subdural hemorrhages typically arise from a blow to the head, while subarachnoid and intracerebral hemorrhages often occur spontaneously due to the rupture of aneurysms or small blood vessels in the brain. Prompt medical attention is crucial in diagnosing and managing brain hemorrhages, as they can have severe neurological consequences and potentially life-threatening implications.
