Subdural haematomas are diagnosed based on a person's medical history, symptoms and the results of a brain scan.

It will also be helpful to know if you take medication to prevent blood clots , such as warfarin or aspirin , as these can increase your chances of developing a subdural haematoma. If necessary,a blood test can be carried out toassess yourblood's ability to clot.

If your GCS score suggests there may be a problem with your brain, a brain scan will be carried out.
Most people with asuspected subdural haematoma will have a type of brain scan called a computerised tomography (CT) scan to confirm the diagnosis.
A CT scan uses X-rays and a computer to create detailed images of the inside of your body. It can show whether any blood has collected between your skull and brain.
In a few cases, a magnetic resonance imaging (MRI) scan may be used to check for a subdural haematoma instead. This is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body.
