Approximately 1% of the general population have a cerebral aneurysm. The risk of having an aneurysm however can be higher if there is a family history of aneurysms or if you suffer from certain medical conditions such as polycystic kidney disease or connective tissue disorders (eg Marfan Syndrome or Ehlers-Danlos Syndrome).
Aneurysm screening involves performing an imaging test, most often an MRI to assess the blood vessels in the brain. This is performed based on your family or medical history even if you do not have any symptoms. Some people however would prefer not to know if they have an aneurysm due to the medical investigations or treatments required if an aneurysm is diagnosed. Dr Bell will discuss with you the positives and negatives of aneurysm screening to assist you in the decision making process.
Current recommendations suggest that you should undergo screening if you have two first degree relatives with brain aneurysms (first degree meaning a parent, sibling or child). Screening can also be considered if you only have one first degree relative with an aneurysm, however this should only be performed following specialist consultation with Dr Bell.
