About Aneurysm in the Brain

Learn the Basics About Brain Aneurysms

A Brain Aneurysm is a weakness or thinning of the wall of a blood vessel in the brain.  The blood vessel wall eventually begins to bulge or balloon outward, similar to a bulge or blow-out on the outside wall of a car tire, as a result of an inherent weakness of the vessel wall in conjunction with the continuous flow and pressure of blood pounding against the thinning wall.  It can have the appearance of a berry hanging on a stem, hence the descriptive name “berry aneurysm”.  Eventually, the bulge or ballooning blood vessel may leak or rupture causing bleeding into the brain, which is referred to as a subarachnoid hemorrhage, a type of hemorrhagic stroke. A ruptured aneurysm quickly becomes life-threatening and requires prompt medical treatment.

Most Brain Aneurysms, however, don’t rupture or create health issues. Such aneurysms are often detected during tests for other, unrelated medical conditions such as headache or following other trauma.  Treatment for an unruptured Brain Aneurysm may be appropriate in some cases and may prevent a rupture in the future.  Brain aneurysms are more common in women, african-americans and in families where several generations have been noted to harbor aneurysms. Most aneurysms develop over time but can be linked to other medical conditions such as hypertension.

Brain Aneurysm symptoms vary by patient and may occur leading up or just prior to a rupture.  For many, the symptoms can be subtle and are often dismissed.  When present, Brain Aneurysm symptoms may be similar to those of other conditions.

To date, the cause of Brain Aneurysms has not yet been identified.  While research suggests possible associations with certain conditions and lifestyles, many cases of Brain Aneurysms develop in individuals who have no known risk factors.

Take the time to know if you're at greater risk of developing a Brain Aneurysm.

Brain Scans MRIs


A Brain Aneurysm is diagnosed through a series of tests including MRI/MRA, CAT Scan, and others.  Having all of the appropriate diagnostic tests done is very important, as the results will help your doctor better determine treatment options and a prognosis.  Many of these tests are also used to monitor a treated or untreated Brain Aneurysm
