Brain aneurysms develop silently. Some people may have inherited a tendency for weak blood vessels, which may lead to the development of aneurysms. Aneurysms in children are rare, and most aneurysms probably develop as a result of wear and tear on the arteries throughout a person’s lifetime. Occasionally, severe head trauma or infection may lead to the development of an aneurysm.
There are a number of risk factors that contribute to the formation of aneurysms, listed below. Two of the most significant are, fortunately, ones that can be controlled: cigarette smoking and high blood pressure (hypertension).
- High blood pressure (hypertension)
- Strong family history of brain aneurysms (familial aneurysms)
- Age (over 40)
- Gender: women have an increased risk of aneurysms
- Race: people of color have an increased risk of ruptured aneurysms
- Other disorders: Ehlers-Danlos syndrome, autosomal dominant polycystic kidney disease, Marfan syndrome, and fibromuscular dysplasia
- Presence of an A particular type of vascular malformation of the brain. An abnormal collection or tangle of arteries and veins located within the substance of the brain in which a maldevelopment of capillaries (which normally connect the arteries and veins) allows a high flow short cut through the brain.
- Congenital abnormality in the A thick-walled blood vessel carrying blood flow from the heart to any organ of the body, including the brain. wall
- Drug use, particularly cocaine
- Excessive alcohol use
- Severe head trauma
