S06.6: Traumatic subarachnoid haemorrhage

You have hurt your brain as a result of a head injury. As a result you have had some bleeding at your brain.

The brain is made up of several areas. For example, the cerebrum is used to think and plan actions. In the cerebellum, movements are initialized and coordinated. The brain stem is responsible for various unconscious tasks such as breathing. The brain stem passes into the spinal cord. The brain is surrounded and protected by skull bone.

You have injured your head. The brain may be damaged as a result. If someone falls heavily on their head, for example, their brain can bang into the wall of their skull.

On the outside of the brain and spinal cord there are three thin meninges (linings). A tough meninx, the dura mater, is on the outside. Below that are two soft meninges. You have had some bleeding in between the two soft linings of your brain. There is not a lot of room in one’s head. When there is bleeding inside the head, the brain can become compressed. Brain tissue may be damaged as a result.
