5 Myths About Brain Aneurysms, Debunked

5 Myths About Brain Aneurysms, Debunked
Perhaps the biggest misconception about brain aneurysms is that having one is a death sentence. This may be due to the perception that “having an aneurysm” is mistaken for having a brain bleed. Read on as we debunk five more myths.

An aneurysm is a bulging area in a weak part of a blood vessel. Most are tiny and cause no problems. It’s only when an aneurysm ruptures that your life may be in danger. 

Our brain aneurysm specialists at Coast Neurosurgical Associates in Long Beach, California, can diagnose and monitor your condition. Understanding aneurysms means knowing the truth from the myths. 

Here are five myths about brain aneurysms, debunked for you with the real facts. Book a consultation today to learn more. 

Myth #1: a severe and sudden headache means you have a ruptured aneurysm

While a severe headache that starts suddenly may be the result of a ruptured aneurysm, it’s not the only cause of thunderclap headaches. However, it is a sign to get a medical assessment as soon as possible. 

Myth #2: aneurysms and strokes are the same 

An aneurysm is a bulge or bubble on a blood vessel, while a stroke refers to a blockage or burst blood vessel in the brain. Some aneurysm ruptures cause hemorrhagic strokes, so there is overlap, but not all strokes happen because of aneurysms, and not all aneurysms cause strokes. 

Myth #3: all aneurysms rupture in time

Aneurysms can be stable, particularly when they’re small. These don’t cause any problems or symptoms, and you can live your entire life not knowing you have one. Once discovered, we will monitor an aneurysm’s progress to keep you safe. 

Myth #4: brain aneurysms can’t be cured

There are multiple surgical treatments to prevent aneurysms from rupturing, including endovascular coiling and surgical clipping. 

Myth #5: aneurysm surgery is high-risk

All surgeries carry risks. While brain surgery in general has a reputation for being high risk, contemporary and minimally invasive techniques reduce the risk of complications while minimizing the impact on healthy tissue. 

Know the signs of brain aneurysms

Successful treatment of brain aneurysms means early detection. However, many aneurysms show no symptoms at all. When symptoms emerge, watch out for: 

  • Dilated pupils
  • Double vision
  • Headaches
  • Numbness or weakness on one side of the face
  • Pain around one eye
  • Seizures
  • Vision loss
  • Light sensitivity
  • Stiff neck
  • Nausea and vomiting
