A brain aneurysm can be classified as ballooning or bulge in a blood vessel of the brain. It can look like a berry hanging from a stem. A brain aneurysm can rupture or leak, causing bleeding in the brain, which is called a hemorrhagic stroke. Many times, a ruptured brain aneurysm can happen in the space that is between the thin tissues covering the brain and the brain itself. This sort of hemorrhagic stroke is known as the subarachnoid hemorrhage. A ruptured aneurysm can very quickly be life-threatening and needs immediate medical attention. Most of the time, however, they do not rupture, cause symptoms or health issues. Such aneurysms are often detected when getting tested for other conditions. For an unruptured brain aneurysm, treatment may be needed in some cases to prevent a rupture from happening in the future. In this article, we will look at brain aneurysm causes and symptoms. If you ever encounter such issues, it is best to go to a hospital for brain aneurysm treatments.
Brain Aneurysm Symptoms
The symptoms of a brain aneurysm depend on whether it is ruptured or not. We will look at the symptoms of both below.
● Ruptured brain aneurysm symptoms
You would need immediate emergency care if there is an intensely painful headache, you lose consciousness, or have some of the following symptoms:
- Sudden intense headache.
- Loss of consciousness.
- Vomiting and nausea.
- Loss of balance and normal coordination.
- Stiff neck.
- Sensitivity to light.
- Dilated pupils.
- Drooping eyelid.
- Sudden double or blurred vision.
- Confusion or issues with mental awareness.
Brain aneurysms do not usually show symptoms, but they can press on the nerves and the brain as they grow bigger.
● Unruptured brain aneurysm symptoms
If you have these symptoms, it is advised that you see a doctor as soon as possible.
- Dropping eyelids.
- Difficulty speaking.
- Double or blurred vision.
- Weakness and numbness on only one side of the face.
- Pain behind and above an eye.
If you get a sudden and intense headache, it can be a sign of a leaking aneurysm. This could lead to a full rupture.
The causes of a brain aneurysm are vastly unknown, but there is a range of factors that can increase the risk of one happening.
There are a number of factors that can contribute to there being a weakness in an artery wall increasing the risk of an aneurysm rupture or a brain aneurysm. They are more common in adults and women. Some of these factors develop over time, while others can be present at birth.
- Here are a few risk factors that can develop over time.
- Old age.
- Heavy consumption of alcohol.
- High blood pressure.
- Drug abuse, mainly the use of cocaine.
- Some can happen after certain blood infections (mycotic aneurysm) or a head injury (dissecting aneurysm).
● Risk factors that are present at birth:
- Family history of brain aneurysms, specifically a first-degree relative.
- Inherited connective tissue disorders that weaken the blood vessels like Ehlers-Danlos syndrome.
- Cerebral arteriovenous malformation; this can be classified as an abnormal connection between the brain’s veins and the arteries that interrupt the normal flow of blood.
- Abnormally narrow aorta; that is, the large blood vessels that bring oxygen-rich blood from the heart to the rest of the body.
- Polycystic kidney disease; this is an inherited disorder that causes the formation of fluid-filled sacs in the kidneys that results in increased blood pressure (hypertension).
