How Do You Know if You Have Had an Aneurysm

Overview

The Dangers of Encephalon Aneurysm

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

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

A encephalon aneurysm can leak or rupture, causing bleeding into the brain (hemorrhagic stroke). Well-nigh ofttimes a ruptured brain aneurysm occurs in the infinite between the brain and the thin tissues covering the encephalon. This type of hemorrhagic stroke is called a subarachnoid hemorrhage.

A ruptured aneurysm rapidly becomes life-threatening and requires prompt medical treatment.

Nigh brain aneurysms, however, don't rupture, create wellness problems or crusade symptoms. Such aneurysms are oft detected during tests for other weather condition.

Treatment for an unruptured encephalon aneurysm may be 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, astringent headache is the central symptom of a ruptured aneurysm. This headache is oftentimes described as the "worst headache" always experienced.

Common signs and symptoms of a ruptured aneurysm include:

Sudden, extremely severe headache
Nausea and vomiting
Stiff neck
Blurred or double vision
Sensitivity to calorie-free
Seizure
A drooping eyelid
Loss of consciousness
Confusion

'Leaking' aneurysm

In some cases, an aneurysm may leak a slight amount of blood. This leaking (picket drain) may cause only a:

Sudden, extremely astringent headache

A more severe rupture often follows leaking.

Unruptured aneurysm

An unruptured encephalon aneurysm may produce no symptoms, specially if it's small. However, a larger unruptured aneurysm may press on brain tissues and nerves, mayhap causing:

Pain above and behind one centre
A dilated pupil
Change in vision or double vision
Numbness of one side of the face

When to see a physician

Seek immediate medical attention if you develop a:

Sudden, extremely severe headache

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

Encephalon aneurysms develop as a issue of thinning artery walls. Aneurysms often 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 near common in arteries at the base of the brain.

Mayo Dispensary Infinitesimal: What is an aneurysm?

An aneurysm is an abnormal burl or ballooning in the wall of a claret vessel.

"A proportion of these patients will go on to have a rupture. And the challenge with rupture is that it'southward 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 surgery, or less-invasive options, such as sealing the ruptured avenue from within the claret vessel with metal coils and/or stents.

Dr. Bendok says 1 to 2 percent of the population have aneurysms, and simply a small percentage of that group will experience a rupture. People who take a family unit history of aneurysms, accept polycystic kidney illness, connective tissue illness, and people who fume are at increased risk of rupture, and should consider screening. If a rupture happens, fast handling can save lives.

Causes

The causes of brain aneurysm are unknown, but a range of factors may increase your chance.

Risk factors

A number of factors tin contribute to weakness in an artery wall and increase the take chances 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 risk factors develop over time; others are present at nascency.

Risk factors that develop over time

These include:

Older age
Cigarette smoking
High claret pressure (hypertension)
Drug abuse, particularly the use of cocaine
Heavy alcohol consumption

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

Risk factors nowadays at birth

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

Inherited connective tissue disorders, such as 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 blood pressure
Abnormally narrow aorta (coarctation of the aorta), the big blood vessel that delivers oxygen-rich claret from the eye to the body
Cognitive arteriovenous malformation (brain AVM), an abnormal connection between arteries and veins in the brain that interrupts the normal menstruation of blood betwixt them
Family unit history of brain aneurysm, particularly a first-caste relative, such every bit a parent, brother, sis, or child

Complications

When a brain aneurysm ruptures, the haemorrhage unremarkably lasts only a few seconds. The blood can cause straight harm to surrounding cells, and the bleeding can damage or kill other cells. It also increases pressure inside the skull.

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

Complications that can develop later on the rupture of an aneurysm include:

Re-bleeding. An aneurysm that has ruptured or leaked is at risk of haemorrhage over again. Re-haemorrhage can crusade further damage to brain cells.
Vasospasm. After a brain aneurysm ruptures, blood vessels in your brain may narrow erratically (vasospasm). This condition tin limit blood menses to brain cells (ischemic stroke) and cause boosted jail cell harm and loss.
Hydrocephalus. When an aneurysm rupture results in bleeding in the space betwixt the encephalon and surrounding tissue (subarachnoid hemorrhage) — most oft the case — the blood can block apportionment of the fluid surrounding the brain and spinal string (cerebrospinal fluid). This condition tin can result in an backlog of cerebrospinal fluid that increases pressure on the brain 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 virtually the base of the brain.

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