Unruptured brain aneurysms occasionally cause symptoms if they're particularly large or press against tissues or nerves inside the brain.
Symptoms of an unruptured brain aneurysm can include:
- visual disturbances, such as loss of vision or double vision
- pain above or around your eye
- numbness or weakness on 1 side of your face
- difficulty speaking
- headaches
- loss of balance
- difficulty concentrating or problems with short-term memory
You should see a GP as soon as possible if you experience symptoms of an unruptured brain aneurysm.
Although most aneurysms will not rupture, it's important to get it checked in case treatment is necessary.
Symptoms of a ruptured brain aneurysm usually begin with a sudden agonising headache.
It's been likened to being hit on the head, resulting in a blinding pain unlike anything experienced before.
Other symptoms of a ruptured brain aneurysm also tend to come on suddenly and may include:
- feeling or being sick
- a stiff neck or neck pain
- sensitivity to light
- blurred or double vision
- sudden confusion
- loss of consciousness
- fits (seizures)
- weakness on 1 side of the body or in any limbs
A ruptured brain aneurysm is a medical emergency. Call 999 immediately and ask for an ambulance if someone's experiencing symptoms of a ruptured brain aneurysm.
