Introduction
A subdural haematoma is a serious brain condition that is caused when blood collects between the skull and the surface of the brain (the subdural space).
Symptoms of subdural haematoma
The symptoms of a subdural haematoma may develop rapidly after a severe head injury, or develop within two to three weeks after a minor head injury.
Causes of subdural haematoma
A subdural haematoma is most often caused by a head injury that ruptures a blood vessel in the space between the skull and the brain (the subdural space).
Diagnosing subdural haematoma
Subdural haematomas are diagnosed based on a person’s medical history, symptoms and the results of an imaging scan of the brain.
Treating subdural haematoma
Surgery is usually recommended to treat a subdural haematoma. Very small subdural haematomas may be monitored first to see if they heal.
Recovering from subdural haematoma
In some cases, a subdural haematoma can cause damage to the brain that requires more time and care to recover from.
