A brain hemorrhage is when a blood vessel in the brain ruptures and blood rapidly fills the brain area.

A brain hemorrhage may be referred to as an epidural, subdural, or subarachnoid hemorrhage depending on where the bleeding is located.

  • Epidural hemorrhages describe bleeding between the brain’s thick outer lining, called dura mater, and the skull.
  • Subdural hemorrhages (most common) describe bleeding between the brain and the dura mater.
  • Subarachnoid hemorrhages describe bleeding between the brain and the thin tissues that immediately surround it.
  • Intracerebral hemorrhages occur inside the brain itself.
