What are the symptoms of an unruptured cerebral aneurysm?

Brain aneurysms can be different for different people. If you discover this disease, you need to find out the cause before treatment. What are the symptoms of an unruptured brain aneurysm?

An aneurysm is a permanent swelling caused by a weakened artery wall. Aneurysms can form anywhere, but the most common and troublesome sites for aneurysms are the cerebral arteries, aorta, and large arteries that carry blood pumped by the heart to the rest of the body. If the aneurysm is relatively small, there are usually no symptoms. For example, the growth of an aneurysm can compress and irritate brain nerve tissue, inducing seizures or uncomfortable symptoms such as headaches and dizziness. Aneurysms will definitely rupture, causing intracranial hemorrhage and acute death.

How are aneurysms caused?

1. Arteriosclerosis

Atherosclerosis of the arterial wall breaks and eliminates elastic fibers, weakening the arterial wall and making it unable to withstand huge pressure. Hardening leads to occlusion of arterial nutrient vessels and degeneration of the blood vessel wall. The age of 60 is a significant stage for the development of arteriosclerosis and is also the age at which aneurysms are prone to occur, which is enough to illustrate the relationship between the two.

2. Infection

It accounts for about 4% of all aneurysms. Infections in various parts of the body can stay in the branches of the cerebral arteries in the form of blood circulation, and a few emboli stay in the bifurcation of the arteries. Infections of the skull base, intracranial abscesses, meningitis, etc. can also erode the arterial wall and cause infectious or fungal aneurysms. The shape of infectious aneurysms is more irregular.

3. Trauma

Closed or open craniocerebral injuries, surgical trauma, direct damage to the arterial wall by foreign objects, instruments, or bone fragments, or traction on the blood vessels leading to weakening of the vessel wall, can form true or false aneurysms.

4. Others

There are also some rare causes, such as tumors, which can also cause aneurysms. Abnormal vascular network diseases at the base of the skull, cerebral arteriovenous malformations, abnormal development of intracranial blood vessels, and cerebral artery occlusion can also be accompanied by aneurysms.

We should understand something from the above introduction. If you encounter these problems, you should follow the methods introduced by the doctor to help the patient recover.
