A brain haemorrhage is bleeding in or around the brain either as a result of ruptured aneurysm, known as a haemorrhagic stroke, or following a significant blow to the head. This section explains the different types of brain haemorrhage while explaining the long-term effects it can cause.
There are four types of haemorrhage, named according to where the bleeding occurs. These are: subdural haemorrhage, extradural haemorrhage, subarachnoid haemorrhage and intracerebral haemorrhage.
Subdural and extradural haemorrhages are the most common type after TBI, and they are a cause of further brain damage that can lead to more long-term effects.
Subarachnoid and intracerebral haemorrhages are more likely to happen spontaneously. Small blood vessels rupture, often causing loss of consciousness. Sometimes a brain haemorrhage can occur after a seemingly minor head injury. Symptoms can develop rapidly or can take a number of weeks to develop, and urgent investigation and treatment is required. The long-term effects of a brain haemorrhage depend on the type and location, but as with all brain injuries, every person's recovery is individual.
