Any injury that includes the brain or skull is a dangerous condition. In a subdural or subarachnoid hemmorrahge or hematoma, bloods that leaks from the blood vessels pool around the subdural or sucarachnoid spaces will occupy the space supposedly for the brain. This in turn create high pressure to the brain. This high pressure in the skull damages the brain tissues. If not treated promptly will cause coma, paralysis and death.
