What causes bleeding in the brain?

ANSWER

The most common causes include:

  • Head trauma.
  • High blood pressure.
  • Aneurysm. This is a weakening in a blood vessel wall that swells. It can burst and bleed into the brain, leading to a stroke.
  • Blood vessel abnormalities (arteriovenous malformations).
  • Amyloid angiopathy. This is an abnormality of the blood vessel walls that sometimes occurs with aging and high blood pressure. It may cause many small, unnoticed bleeds before causing a large one.
  • Blood or bleeding disorders.
  • Liver disease.
  • Brain tumors.
