What are the symptoms of brain aneurysms?

Most brain aneurysms don’t have any symptoms until they burst. Symptoms of a ruptured aneurysm may include:

  • an unusually severe headache (the most common symptom)
  • vomiting
  • stiff neck
  • sensitivity to light
  • weakness
  • trouble with thinking or memory
  • seizures
  • loss of consciousness

What are the causes of brain aneurysms?

Although aneurysms can occur with no known cause, aneurysms in children can be caused by severe head trauma, connective tissue disorders or an infection.

Brain aneurysms can sometimes run in families or can occur as part of a broader genetic disorder, such as Marfan syndrome, Ehlers-Danlos syndrome or polycystic kidney disease.
