An epidural hematoma occurs as a result of arterial bleeding between the skull and dura matter.This bleeding usually occurs when the middle meningeal artery is torn by a fracture of the temporal and/or parietal bone.As a result of rapid arterial bleeding,signs and symptoms develop swiftly-usually within several hours.In contrast,signs and symptoms of subdural hematoma develop over days or months because of low pressure venous bleeding.Subarachnoid hemorrhage usually produces a sudden excruciating headache accompanied by a brief loss of consciousness.
