Brain Aneurysm

Symptoms and Signs of Brain Aneurysm

One of the early symptoms of a brain aneurysm is a sudden, severe headache caused by a “sentinel” hemorrhage, when a small amount of blood leaks into the brain before an actual rupture occurs. By pressing on nearby nerves, an unruptured aneurysm may still cause vision loss and eye pain as well as headaches in some cases.
In many cases, an aneurysm is only detected after a subarachnoid hemorrhage (SAH), a medical emergency requiring immediate attention. The signs of a brain aneurysm that has ruptured may include:
  • Severe headache
  • Eye pain
  • Dilated pupils with sensitivity to light
  • Drooping eyelids
  • Sudden double vision
  • Impaired speech
  • Decreased feeling or numbness in parts of the body
  • Stiff neck, back or leg pain
  • Pausea and vomiting
  • Loss of balance
  • Loss of consciousness
  • Coma
  • Sudden death
Several of these symptoms of a brain aneurysm may also indicate other conditions, some serious. The appearance of any of these symptoms warrants an immediate consultation visit to the emergency.
