How Will You Know if You Have Aneurysm

Overview

The Dangers of Brain Aneurysm

Aneurysms can lurk without symptoms, but screening can save lives.

A brain aneurysm (AN-yoo-riz-um) is a bulge or ballooning in a claret vessel in the brain. It often looks similar a berry hanging on a stem.

A brain aneurysm can leak or rupture, causing haemorrhage into the brain (hemorrhagic stroke). Nigh oft a ruptured brain aneurysm occurs in the space between the brain and the thin tissues covering the brain. This type of hemorrhagic stroke is called a subarachnoid hemorrhage.

A ruptured aneurysm speedily becomes life-threatening and requires prompt medical handling.

Almost brain aneurysms, however, don't rupture, create wellness problems or cause symptoms. Such aneurysms are oftentimes detected during tests for other conditions.

Treatment for an unruptured brain aneurysm may exist advisable in some cases and may prevent a rupture in the future. Talk with your caregiver to ensure you understand the best options for your specific needs.

Symptoms

Ruptured aneurysm

A sudden, severe headache is the key symptom of a ruptured aneurysm. This headache is often described as the "worst headache" ever experienced.

Common signs and symptoms of a ruptured aneurysm include:

Sudden, extremely severe headache
Nausea and airsickness
Stiff neck
Blurred or double vision
Sensitivity to light
Seizure
A drooping eyelid
Loss of consciousness
Confusion

'Leaking' aneurysm

In some cases, an aneurysm may leak a slight amount of blood. This leaking (sentinel bleed) may cause simply a:

Sudden, extremely severe headache

A more severe rupture ofttimes follows leaking.

Unruptured aneurysm

An unruptured brain aneurysm may produce no symptoms, specially if information technology's small. Withal, a larger unruptured aneurysm may printing on brain tissues and nerves, possibly causing:

Pain above and behind one center
A dilated student
Alter in vision or double vision
Numbness of i side of the confront

When to see a medico

Seek immediate medical attention if y'all develop a:

Sudden, extremely severe headache

If you're with someone who complains suddenly, severe headache or who loses consciousness or has a seizure, call 911 or your local emergency number.

Brain aneurysms develop as a result of thinning artery walls. Aneurysms oftentimes form at forks or branches in arteries because those sections of the vessel are weaker.

Although aneurysms can appear anywhere in the brain, they are most mutual in arteries at the base of the encephalon.

Mayo Clinic Minute: What is an aneurysm?

An aneurysm is an aberrant bulge or ballooning in the wall of a blood vessel.

"A proportion of these patients volition get on to have a rupture. And the claiming with rupture is that it's unpredictable."

Dr. Bernard Bendok says a ruptured aneurysm is a medical emergency that can cause life-threatening bleeding in the encephalon.

"The typical presentation is somebody who has the worst headache of their life."

Fast treatment is essential. It includes open up surgery, or less-invasive options, such as sealing the ruptured avenue from inside the claret vessel with metallic coils and/or stents.

Dr. Bendok says ane to 2 percentage of the population take aneurysms, and just a modest percentage of that grouping will experience a rupture. People who have a family history of aneurysms, have polycystic kidney disease, connective tissue disease, and people who smoke are at increased risk of rupture, and should consider screening. If a rupture happens, fast treatment tin salve lives.

Causes

The causes of encephalon aneurysm are unknown, but a range of factors may increment your risk.

Run a risk factors

A number of factors can contribute to weakness in an avenue wall and increase the risk of a brain aneurysm or aneurysm rupture. Encephalon aneurysms are more common in adults than in children and more common in women than in men.

Some of these run a risk factors develop over time; others are present at birth.

Adventure factors that develop over fourth dimension

These include:

Older historic period
Cigarette smoking
High claret pressure (hypertension)
Drug abuse, specially the employ of cocaine
Heavy alcohol consumption

Some types of aneurysms may occur after a head injury (dissecting aneurysm) or from certain blood infections (mycotic aneurysm).

Risk factors present at birth

Selected atmospheric condition that date to nascency can be associated with an elevated risk of developing a brain aneurysm. These include:

Inherited connective tissue disorders, such every bit Ehlers-Danlos syndrome, that weaken blood vessels
Polycystic kidney disease, an inherited disorder that results in fluid-filled sacs in the kidneys and usually increases claret pressure
Abnormally narrow aorta (coarctation of the aorta), the big blood vessel that delivers oxygen-rich blood from the heart to the body
Cognitive arteriovenous malformation (brain AVM), an abnormal connexion between arteries and veins in the brain that interrupts the normal menstruation of blood between them
Family history of encephalon aneurysm, peculiarly a starting time-caste relative, such as a parent, brother, sister, or child

Complications

When a brain aneurysm ruptures, the bleeding normally lasts only a few seconds. The blood can cause directly damage to surrounding cells, and the bleeding tin can damage or kill other cells. It also increases pressure level within the skull.

If the pressure becomes too elevated, the blood and oxygen supply to the encephalon may be disrupted to the point that loss of consciousness or even death may occur.

Complications that tin develop after the rupture of an aneurysm include:

Re-haemorrhage. An aneurysm that has ruptured or leaked is at risk of bleeding again. Re-bleeding can crusade further harm to brain cells.
Vasospasm. After a encephalon aneurysm ruptures, claret vessels in your brain may narrow erratically (vasospasm). This status can limit claret menses to brain cells (ischemic stroke) and crusade additional jail cell damage and loss.
Hydrocephalus. When an aneurysm rupture results in bleeding in the infinite betwixt the encephalon and surrounding tissue (subarachnoid hemorrhage) — most ofttimes the case — the blood tin can cake circulation of the fluid surrounding the brain and spinal cord (cerebrospinal fluid). This condition can consequence in an backlog of cerebrospinal fluid that increases pressure level on the encephalon and can damage tissues (hydrocephalus).
Hyponatremia. Subarachnoid hemorrhage from a ruptured brain aneurysm can disrupt the balance of sodium in the blood. This may occur from damage to the hypothalamus, an surface area near the base of the brain.

A drib in blood-sodium levels (hyponatremia) can lead to swelling of brain cells and permanent damage.
