A brain aneurysm or cerebral aneurysm is a swelling in a vulnerable region of an artery wall in or near the brain. The blood flow’s continuous pressure pushes the weakened area outward, resulting in a bump resembling a blister.

• The walls of a brain vessel become fragile and brittle, causing brain aneurysms. Although they can develop anywhere in the brain, mostly grows in the large arteries along the bottom of the skull. They typically form at the places where vessels diverge.
• An artery wall congenital disability can occasionally cause an individual to be born with a brain aneurysm. An artery can become weaker due to many variables.

There are no symptoms if a brain aneurysm is tiny or has not ruptured. But if it pushes against the brain or nerves, it may cause symptoms like:

• A widened pupil.
• Pain behind and above the eye.
• A visual disturbance.
• One sided facial numbness.
• Weakness.
• Numbness.

Some risk factors for brain aneurysms, such as a person’s age or genetic makeup, cannot be prevented or altered by humans. However, people can reduce their chance of getting a brain aneurysm by:

• Manage elevated blood pressure with medication and lifestyle adjustments.
• Exercise frequently and stay away from repetitive heavy lifting.
• Avoid smoking cigarettes.
• Seek help for alcohol addiction, if any.
• Avoid using cocaine and other stimulants.
• Maintain a healthy diet.
• Reduce stress.
