Brain Aneurysm Growth Rate Statistics

In this post, we will explore key statistics related to brain aneurysms, a serious condition affecting approximately 6% of the general population. Understanding factors such as growth rates, rupture risks, and demographic trends can provide valuable insights into the management and prevention of this potentially life-threatening condition.

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."

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.
