What is Subdural Hematomas?

In subdural hematoma, blood accumulates between the layers of the tissues that encompass the cerebrum. This causes bleeding between the dura (the peripheral layer) and the arachnoid (the following layer). The bleeding in a subdural hematoma happens under the skull and outside the cerebrum. The accumulation of blood often leads to high blood pressure which is dangerous for the patient.
