Brain Aneurysm Symptoms & Diagnosis

Symptoms

If you have any of these symptoms, do not assume it is due to a brain aneurysm. These symptoms may be caused by other conditions. Tell your doctor if you have any of these:

Pain behind the eye
Numbness, sometimes on one side of the face or body
Weakness on one side of the body or face
Vision changes
Drooping eyelid

Most aneurysms do not cause symptoms until they leak or rupture. A leaking or ruptured aneurysm may cause:

Headache
Nausea
Vomiting
Stiff neck
Loss of consciousness

Diagnosis

Your doctor will ask about your symptoms and medical history, and perform a physical exam. Tests may include the following:

Brain imaging, such as CT scan (x-rays seen on a computer) or MRI (magnetic waves are used to view images of the body)
Catheter , MRI , or CT angiography (dye contrast test to view the arteries and veins)
Spinal fluid analysis
