What happens to the brain when there is bleeding inside the head?

Since the brain cannot store oxygen, it relies upon a series of blood vessels to supply oxygen and nutrients. When a brain hemorrhage occurs, oxygen may no longer be able to reach the brain tissue supplied by these leaky or burst vessels. Pooling of blood from an intracranial hemorrhage or cerebral hemorrhage also puts pressure on the brain and deprives it of oxygen.

When a hemorrhage interrupts blood flow around or inside the brain, depriving it of oxygen for more than three or four minutes, the brain cells die. The affected nerve cells and the related functions they control are damaged as well.
