How are subdural haematomas caused and what are the symptoms?

They are often caused by trauma to the head or can be associated with anti-coagulant (blood thinning) medication such as Warfarin.

What are the symptoms?
The skull is like a closed box and the brain fits very snugly within this box. As the blood clot forms it takes up room squashing the brain which in turn causes the pressure within the skull (intracranial pressure) to increase. This increase in pressure can affect the structure and function of the brain. Symptoms such as drowsiness, headaches, confusion, limb weakness and visual problem begin to show.
