With sources from: ncbi.nlm.nih.gov, mayoclinic.org, stroke.org, bafound.org and many more

Statistic 1

Brain aneurysms affect about 6% of the general population.

Statistic 2

On average, an aneurysm will grow 1-2 mm per year.

Statistic 3

The risk of rupture increases by 12% for every additional millimeter of size.

Statistic 4

Growth and rupture risk of small unruptured intracranial aneurysms (UIAs) vary from 4% to 14.5%.

Statistic 5

UIAs smaller than 7 mm have over ~2% annual risk for rupture.

Statistic 6

Brain aneurysms are most prevalent in people ages 35 to 60.

Statistic 7

Women, specifically post-menopausal women, are more likely to have brain aneurysms as they have higher growth rates.

Statistic 8

The rate of growth for intracranial aneurysms is 1.8%-3.1% per year.

Statistic 9

10-15% of patients with a ruptured aneurysm die before reaching the hospital.

Statistic 10

Most brain aneurysms only show symptoms when they rupture.

Statistic 11

People with a family history of brain aneurysms are twice as likely to have an aneurysm.

Statistic 12

The Aneurysm's size plays a significant role in its growth where aneurysms larger than 7mm have a high annual growth rate.

Statistic 13

Hypertension increases the likelihood of an aneurysm's growth.

Statistic 14

The median size of aneurysmal SAH is 8 mm.

Statistic 15

As per United States, brain aneurysm rupture accounts for 3–5% of all new strokes.

Interpretation

Brain aneurysms are a significant health concern, affecting a notable portion of the general population. The growth rate of an aneurysm and its size play crucial roles in determining the risk of rupture, with larger aneurysms having a higher annual growth rate and consequently a higher risk of rupture. Various factors such as age, gender, family history, and hypertension contribute to the likelihood of an aneurysm developing and growing. It is important to be aware of these statistics and risk factors to better understand and potentially prevent the serious consequences associated with brain aneurysms, including the alarming rate of mortality among those with a ruptured aneurysm.
