Brain Aneurysm Symptoms & Signs

Aneurysms usually cause no symptoms unless they rupture and cause bleeding into the brain. Often, an aneurysm is found when a CAT scan or MRI is performed for an unrelated reason. Occasionally, the aneurysm gets big enough to compress nearby structures and can cause symptoms such as:

• Double vision
• Loss of vision
• Headaches
• Eye and/or neck pain

Symptoms of an aneurysm that has bled may include:

• Sudden occurrence of a headache (severe or described as "the worst in patient's experience")
• Headaches with nausea or vomiting
• Stiff neck (occasionally)
• Muscle weakness, difficulty moving any part of the body
• Numbness or decreased sensation in any part of the body
• Vision changes (double vision, loss of vision)
• Eye lid drooping
• Changes in mental status, the person may be confused, lethargic, sleepy, or stuporous
• Seizures
• Slow, sluggish, lethargic movement
• Speech impairment
• Sudden onset of irritability, impulsivity or poor temper control
