Bleeding into the brain from a ruptured blood vessel. It is 1 of the 3 principal mechanisms by which a stroke can occur. It mainly affects middle-aged or elderly people and is usually due to atherosclerosis. Untreated hypertension increases the risk of intracerebral haemorrhage.
The ruptured artery is usually in the cerebrum. The escaped blood seeps out, damaging brain tissue. The symptoms are sudden headache, weakness, and confusion, and often loss of consciousness. Speech loss, facial paralysis, or onesided weakness may develop, depending on the area affected. Surgery is usually impossible; treatment is aimed at lifesupport and the reduction of blood pressure. Large haemorrhages are usually fatal. For the survivor of an intracerebral haemorrhage, rehabilitation and outlook are as for any type of stroke.

A haemorrhage into the subarachnoid space in the BRAIN. It is usually the result of rupture of an ANEURYSM on the CIRCLE OF WILLIS. Head injury or intense physical exercise occasionally cause subarachnoid haemorrhage; the diagnosis is con?rmed by CT scan or by identifying blood in the CEREBROSPINAL FLUID at LUMBAR PUNCTURE. Cerebral ANGIOGRAPHY will usually pinpoint the site of bleeding. Treatment is bed rest, life-support measures and procedures to reduce blood pressure; sometimes surgery is carried out but not usually until several weeks after the acute episode. About 30 per cent of patients recover fully, whilst some have residual disabilities such as EPILEPSY, mental deterioration or paralysis. About 50 per cent of those affected die.... subarachnoid haemorrhage
Bleeding within or around the brain that is caused either by injury or by spontaneous rupture of a blood vessel. There are 4 possible types of brain haemorrhage: subdural, extradural, subarachnoid, and intracerebral. Extradural and subdural haemorrhages are usually the result of a blow to the head (see head injury). Subarachnoid and intracerebral haemorrhages usually occur spontaneously due to rupture of aneurysms or small blood vessels in the brain.... brain haemorrhage
Bleeding into the vitreous humour. A common cause is diabetic retinopathy. Vitreous haemorrhage often affects vision; a major haemorrhage causes poor vision until the blood is reabsorbed, which may not be for several months, if at all.... vitreous haemorrhage
(PVH) a significant cause of morbidity and mortality in infants who are born prematurely in which bleeding occurs from fragile blood vessels around the *ventricles in the brain. Bleeding extending into the lateral ventricles is termed intraventricular haemorrhage (IVH) and in severe cases can extend into the brain tissue (cerebral parenchyma). Surviving infants may have long-term neurological deficits, such as cerebral palsy, developmental delay, or seizures.... periventricular haemorrhage
