Brain Aneurysm-the balloon may blast anytime

by HARRY KELLY Medical Consultant A brain aneurysm is a condition characterized by formation of a bulge in blood vessels in the brain. It is usually caused by thinning or degenerating of artery walls.

Description=

Brain aneurysm is a formation of bulge or balloon in the brain arteries. It usually develops at the base of brain or where the arteries are weaker especially at the forks. However, this bulge can occur anywhere in the brain and can create health problems.

When this bulge leaks or causes bleeding, it can cause hemorrhagic stroke. Subarachnoid hemorrhage or bleeding caused in the space between brain and surrounding tissues can be life threatening.

Signs and symptoms:-

•Ruptured aneurysm: - Sudden and severe headache is the typical symptom of Ruptured aneurysm. Other signs and symptoms are as follows:-

1.Vision problems such as blurred or double vision
2.Sensitivity to light
3.Epilepsy attack or seizures
4.Stiff neck
5.Nausea and vomiting
6.Fainting
7.Confusion


In some cases, this condition may cause slight leaking of blood. It causes headache and is usually a warning sign of ruptured aneurysm.

•Unruptured aneurysm: - Unruptured aneurysm, if smaller in size generally causes no symptoms. However, if it is larger in size, it can exert pressure or brain and nerves causing various symptoms.

1.Changes in vision
2.Eye pain especially in the back of eye
3.Dilation of pupil
4.Double vision
5.Drooping eyelid
6.Facial paralysis usually in one side of face

Risk factors:-

1.Old age
2.Being female
3.Hypertension
4.Hardening of the arteries
5.Drug abuse
6.Heavy Alcohol consumption
7.Smoking
8.Lowered estrogen levels after menopause
9.Head injury
10.Blood infections
Risk factors during birth:-
1.Ehlers-Danlos syndrome
2.Inherited connective tissues disorders
3.Polycystic kidney disease – cysts formation in kidneys that leads to high blood pressure
4.Coarctation of the aorta which is responsible for supply of oxygen rich blood to the body
5.Cerebral arteriovenous malformation (brain AVM) which interrupts blood flow between arteries and veins in the brain
6.Family history

In case of rupture of brain aneurysm, bleeding or hemorrhage occurs. It affects surrounding tissues and cells causing permanent damage. Even if bleeding lasts for a few seconds, it may increase pressure inside the skull. The brain may be deprived of oxygen and nutrients supply when the pressure is too higher. In these cases, loss of consciousness or death may also occur.

Complications: - Complications occur after rupture of aneurysm.

1. Vasospasm: - Vasospasm is caused by narrowing of blood vessels in the brain. This condition can cause ischemic stroke by limiting blood supply to brain vessels causing their death or damage. It can lead to loss of various functions.

2. Hydrocephalus: - After the aneurismal rupture, blood may get saturated between the brain and surrounding areas. This condition is known as subarachnoid hemorrhage. It can cause blocking of cerebrospinal fluid causing Hydrocephalus or excessive pressure of cerebrospinal fluid on the brain. This condition can cause severe damage to brain tissues.

3. Hyponatremia: - Subarachnoid hemorrhage can cause damage to hypothalamus. It may trigger sodium imbalance in the blood supply. Reduced sodium amount in blood is known as Hyponatremia which is associated with swelling and damage of brain cells.

4. Re-bleeding:- Ruptured aneurysm increases the risk of re-bleeding. It may lead to further damage to blood cells.
