Our brain is encased in the skull, however between inner surface of the skull and outer surface of the brain we have three layers of tissue that surround the brain. The innermost layer is called the pia mater (pia for short), the next layer is called the arachnoid and the outer most and the toughest layer is called the dura mater (dura). A subdural haematoma is a collection of blood (blood clot) that occurs between the outer two layers, the dura and arachnoid.
Subdural haematomas develop as a result of a traumatic head injury. This can occur during sporting accidents or incidents, car accidents and cases of violence. It can also occur from alcoholism and anticoagulant medications and old age.
Since subdural haematomas can place tension and compression on any part of the brain there is a large range of symptoms that a patient may present with. Subdural haematoma symptoms may include nausea, vomiting, dizziness, headaches and muscle weakness.
Medical treatment is required promptly with a subdural haematoma.
