<P> A subdural hematoma ( SDH ) , is a type of hematoma , usually associated with traumatic brain injury . Blood gathers between the inner layer of the dura mater and the arachnoid mater . Usually resulting from tears in bridging veins which cross the subdural space , subdural hemorrhages may cause an increase in intracranial pressure ( ICP ) , which can cause compression of and damage to delicate brain tissue . Subdural hematomas are often life - threatening when acute . Chronic subdural hematomas , however , have a better prognosis if properly managed . </P>
