Risk Factors You Cannot Change
- Age (most commonly diagnosed between ages 35 and 60)
- Female sex
- Family history of brain aneurysms
- Certain inherited connective tissue disorders
- Previous brain aneurysm
Risk Factors You Can Help Manage
- High blood pressure
- Smoking
- Heavy alcohol use
- Use of stimulant drugs such as cocaine or amphetamines
- Head injuries
What Should You Do?
If you develop a sudden, severe headache unlike any you’ve experienced before—especially if it is accompanied by vomiting, confusion, weakness, vision changes, or loss of consciousness—seek emergency medical care immediately.
If you have persistent neurological symptoms that are new or unusual, arrange prompt evaluation by a healthcare professional. Early diagnosis allows doctors to determine the cause and recommend appropriate treatment.
How Brain Aneurysms Are Diagnosed
Depending on your symptoms, healthcare providers may recommend one or more imaging tests, including:
- CT scan
- CT angiography (CTA)
- MRI or MRA
- Cerebral angiography
Treatment Options
Treatment depends on the size, location, and condition of the aneurysm.
Small unruptured aneurysms may simply be monitored with periodic imaging, while others may require procedures such as surgical clipping or endovascular coiling to reduce the risk of rupture.
Ruptured aneurysms require emergency treatment to stop bleeding and manage potentially life-threatening complications.
Reducing Your Risk
- Keep blood pressure under control.
- Avoid smoking or seek support to quit.
- Limit excessive alcohol consumption.
- Avoid recreational stimulant drugs.
- Maintain regular medical checkups.
- Discuss your family history with your healthcare provider.
Final Thoughts
Many brain aneurysms never cause symptoms, but when warning signs do appear, recognizing them quickly is essential. Sudden severe headache, neurological changes, vision problems, weakness, or loss of consciousness should always be treated as medical emergencies.
Prompt evaluation and treatment provide the best opportunity to reduce complications and improve outcomes. If you or someone nearby develops symptoms suggestive of a brain aneurysm or stroke, seek emergency medical care without delay.
