A diagnosis of Epidural Hematoma is begun with a neurological examination and a discussion of symptoms. Signs of increased cranial pressure included headaches, drowsiness, confusion, nausea and vomiting. A head CT scan is used to confirm the diagnosis. An MRI may also be used to help locate the bleed. An EEG may also be used to assess the brain’s electrical activity.


  • Lifesaving measures such as CPR and life support.
  • Medications can be used to reduce swelling and pressure and can be treated with out surgery if mild.
  • Brain surgery such as drilling into the brain to release pressure, stopping bleeding, or removing blood clots through a procedure called a craniotomy.
  • Additional medications to control seizures and thin blood.


Recovery for people who survive Epidural Hematomas can very greatly as each person’s injury and complications are unique. Often people will need some sort of rehabilitation therapy due to continued weakness in some body part, incontinence, issues walking, paralysis or loss of sensation. People recovering from Epidural Hematomas often will need home care services after leaving rehab.
