Signs Of A Brain Aneurysm You Should Know

Warning Signs for Brain Aneurysms

One of the potentially life-threatening conditions could be a brain aneurysm. This is a condition that affects the brain and it can take several forms. It is better to know about the signs of a brain aneurysm to avoid any delay in the diagnosis and treatment procedure. Read below to know about the 6 signs of a brain aneurysm you should know.

Treating An Unruptured Aneurysm

A flow diverter, endovascular coiling or surgical clipping can be used to close off an unruptured aneurysm and inhibit it from leaking or rupturing in the future. However, for some patients, the risk of these procedures might outweigh their benefits.

The threat the aneurysm poses to the patient’s health will be evaluated by a neurologist and an interventional neuroradiologist or neurosurgeon to determine if treatment is appropriate.

What Causes An Aneurysm

There is not an easily definable, predictable, or preventable cause of a brain aneurysm. Some aneurysms are present at birth, and others develop later in life due to inherited and/or external factors.

Risk factors for an aneurysm that are present at birth include:

  • Inherited connective tissue diseases such as Ehlers-Danlos syndrome. These conditions can make blood vessels unusually weak.
  • Inherited polycystic kidney disease. This condition causes cysts to form in the kidneys, and it also usually causes high blood pressure that can cause an aneurysm.
  • Arteriovenous malformation. This condition causes blood vessels to develop into tangles through which blood does not pass normally. When this happens in the brain, an aneurysm can result.
  • Family history. If a parent or sibling has suffered from an aneurysm, an individual is more likely to develop an aneurysm themselves.

Risk factors that may contribute to the development of an aneurysm later in life include:

  • Smoking

What Are The Symptoms

Guide to a Brain Aneurysm

Unruptured aneurysm Most cerebral aneurysms do not show symptoms until they either become very large or rupture. Small unchanging aneurysms generally will not produce symptoms.

A larger aneurysm that is steadily growing may press on tissues and nerves causing:

  • pain above and behind the eye
  • numbness
  • paralysis on one side of the face
  • a dilated pupil in the eye
  • vision changes or double vision.

Ruptured aneurysmWhen an aneurysm ruptures , one always experiences a sudden and extremely severe headache and may also develop:

  • double vision

TypeThere are three types of cerebral aneurysms:

  • Saccular aneurysm. A saccular aneurysm is a rounded sac containing blood, that is attached to a main artery or one of its branches. Also known as a berry aneurysm , this is the most common form of cerebral aneurysm. It is typically found on arteries at the base of the brain. Saccular aneurysms occur most often in adults.
  • Fusiform aneurysm. A fusiform aneurysm balloons or bulges out on all sides of the artery.
  • Mycotic aneurysm. A mycotic aneurysm occurs as the result of an infection that can sometimes affect the arteries in the brain. The infection weakens the artery wall, causing a bulging aneurysm to form.

SizeAneurysms are also classified by size: small, large, and giant.

  • Small aneurysms are less than 11 millimeters in diameter .
  • Large aneurysms are 11 to 25 millimeters .
  • Giant aneurysms are greater than 25 millimeters in diameter .

What Causes A Brain Aneurysm

Brain aneurysms happen due to structural changes in the walls of an artery in the brain. These changes cause the walls of the artery to get weaker and become thin. The deformity can happen due to thinning of the wall, but sometimes inflammation or trauma can cause the deformity without thinning.

Its still unclear what exactly causes aneurysms to form. However, its believed that one or a combination of the following factors may promote their development:

  • a break down of elastic tissue within the artery
  • stress from blood flow through the artery
  • tissue changes in the artery due to increases in inflammation

Brain aneurysms are also more likely to happen where an artery branches into different directions. This is because arteries are naturally weaker at these locations.

Its possible for aneurysms to be present from birth. However, they most often develop over the course of your lifetime. This can be due to a variety of risk factors that well discuss below.

What You Need To Know

  • A brain aneurysm is a ballooning arising from a weakened area in the wall of a blood vessel in the brain.
  • If the brain aneurysm expands and the blood vessel wall becomes too thin, the aneurysm will rupture and bleed into the space around the brain. This event is called a subarachnoid hemorrhage and may cause a hemorrhagic stroke.
  • Rupturing brain aneurysm and SAH are life-threatening events. If you suspect you are having a rupturing brain aneurysm, call 911.

A brain aneurysm is a protuberance or enlargement of any artery within the brain. An aneurysm can form in delicate or weakened sites in the arterial walls. A small-sized aneurysm does not cause any symptoms.

The initial warning signs might arise once it grows large enough to crush on the nerves or if it leaks blood into the brain or ruptures.

How Are Cerebral Aneurysms Treated

Not all cerebral aneurysms require treatment. Some very small unruptured aneurysms that are not associated with any factors suggesting a higher risk of rupture may be safely left alone and monitored with MRA or CTA to detect any growth. It is important to aggressively treat any coexisting medical problems and risk factors.

Treatments for unruptured cerebral aneurysms that have not shown symptoms have some potentially serious complications and should be carefully weighed against the predicted rupture risk.

Treatment considerations for unruptured aneurysms A doctor will consider a variety of factors when determining the best option for treating an unruptured aneurysm, including:

  • type, size, and location of the aneurysm
  • risk of rupture
  • the persons age and health
  • personal and family medical history
  • risk of treatment.

Individuals should also take the following steps to reduce the risk of aneurysm rupture:

  • carefully control blood pressure
  • avoid cocaine use or other stimulant drugs.

Treatments for unruptured and ruptured cerebral aneurysms Surgery, endovascular treatments, or other therapies are often recommended to manage symptoms and prevent damage from unruptured and ruptured aneurysms.SurgeryThere are a few surgical options available for treating cerebral aneurysms. These procedures carry some risk such as possible damage to other blood vessels, the potential for aneurysm recurrence and rebleeding, and a risk of stroke.

Endovascular treatment

What Is The Treatment For Cerebral Aneurysms

Not all cerebral aneurysms burst. Some individuals with very small aneurysms may be monitored to detect any growth or onset of symptoms and to ensure aggressive treatment of coexisting medical problems and risk factors. Each case is unique, and considerations for treating an unruptured aneurysm include the type, size and location of the aneurysm annual risk of rupture patients age, health and personal and family medical history and risk of treatment.

Two invasive options are available for treating cerebral aneurysms, both of which carry some risk to the individual . They include:

Endovascular embolization is an alternative to surgery. Once the individual has been anesthetized, the doctor inserts a hollow plastic tube into an artery and threads it, using fluoroscopic angiography, through the body to the site of the aneurysm. Using a guide wire, detachable coils are passed through the catheter and released into the aneurysm. The coils fill the aneurysm, block it from circulation and cause the blood within the aneurysm sac to clot, which effectively destroys the aneurysm. The procedure may need to be performed more than once during the persons lifetime.

Individuals who have suffered a subarachnoid hemorrhage often need rehabilitative, speech and occupational therapy to regain lost function and learn to cope with any permanent disability.

Aneurysms Affect People Differently

Although they still arent completely understood, aneurysms are being discovered more frequently than they used to be. This means you could be seeing a doctor for an unrelated issue and a test or imaging scan will show an aneurysm.

If this happens, think of it as crucial knowledge to act on. Talk to your doctor or a specialist about ways to lessen your chance of rupture, like lowering your blood pressure and quitting smoking, and how to monitor it. Consider seeing a neurosurgeon who specializes in treating aneurysms.

Its important to be prepared for the worst while also taking steps to prevent the worst from happening.

Who Performs The Procedure

Brain Surgeon Explains the Warning Signs of An Aneurysm to Never Ignore

Surgical clipping of a cerebral aneurysm is always performed by a neurosurgeon, often one with expertise in cerebrovascular disease. Most cerebrovascular neurosurgeons have had five to seven years of general neurosurgery training and an additional one to two years of specialized cerebrovascular training.

Endovascular coiling is done either by a neurosurgeon or by an interventional neuroradiologist. An interventional radiologist has undergone extensive training in both radiology and interventional procedures involving the brain and spinal cord. All neurosurgeons that perform endovascular coiling have undergone additional training in endovascular techniques in addition to full neurosurgery training .

Are There Any Warning Signs Before A Brain Aneurysm

The ballooning of a blood vessel located in the brain is called a brain aneurysm. It leads to a bulge developing in the blood vessel, and this can rupture or leak in the brain, causing a type of hemorrhagic stroke known as a subarachnoid hemorrhage.

A ruptured brain aneurysm is a life-threatening condition that requires immediate medical care. Brain aneurysms are typically the result of thinning artery walls. They usually form at branches or forks in arteries since these are the weakest parts. They can develop on any part of the brain but typically at the base.

Most people develop brain aneurysms that do not rupture, so they do not lead to any health issues. These types of aneurysms are typically detected while the patient is being tested for some other condition.

Treating a brain aneurysm that has not ruptured might prevent a life-threatening condition from occurring in the future. Each patient’s circumstances are unique, so the doctor will advise them on the best way to proceed if an unruptured aneurysm is detected.

How Is An Aneurysm Detected

When a brain aneurysm ruptures or leaks, life-threatening complications can set in within minutes. The patient must receive emergency medical treatment immediately. If someone near you experiences a sudden, extreme, unexplained headache, has a seizure, or loses consciousness, call 911 or your local emergency medical number immediately.

If an unruptured aneurysm is detected with an imaging exam, your doctor may suggest treatment to prevent a rupture from happening in the future.

Imaging scans are generally not used to screen for brain aneurysms in healthy patients. However, some doctors may recommend screening for people who have a family history of aneurysms or who have a medical condition that increases the risk of an aneurysm.

Warning Signs Of A Ruptured Aneurysm

An aneurysm can either burst or leak. However, if it starts leaking, a more severe rupture typically follows.

As blood leaks into your brain, it can damage or kill other cells and increase pressure within your skull. As the pressure rises, it can also interfere with the blood and oxygen supply to your brain and lead to a loss of consciousness or even death.

One of the most obvious signs of a ruptured aneurysm is intense head pain, typically described as the worst headache of your life. Additional symptoms of a ruptured aneurysm include:

  • Nausea and vomiting
  • Confusion
  • Loss of consciousness

Early detection is essential for treating ruptured aneurysms. You should consider these symptoms a medical emergency and immediately seek medical attention, especially if you also have a sudden and extremely severe headache.

What Causes A Cerebral Aneurysm

Living With an Unruptured Brain Aneurysm – My Story

Cerebral aneurysms form when the walls of the arteries in the brain become thin and weaken. Aneurysms typically form at branch points in arteries because these sections are the weakest. Occasionally, cerebral aneurysms may be present from birth, usually resulting from an abnormality in an artery wall.

Risk factors for developing an aneurysm

Sometimes cerebral aneurysms are the result of inherited risk factors, including:

  • genetic connective tissue disorders that weaken artery walls
  • polycystic kidney disease
  • arteriovenous malformations
  • history of aneurysm in a first-degree family member .

Other risk factors develop over time and include:

  • untreated high blood pressure
  • cigarette smoking
  • drug abuse, especially cocaine or amphetamines, which raise blood pressure to dangerous levels. Intravenous drug abuse is a cause of infectious mycotic aneurysms.
  • age over 40.

Less common risk factors include:

  • head trauma
  • brain tumor
  • infection in the arterial wall .

Additionally, high blood pressure, cigarette smoking, diabetes, and high cholesterol puts one at risk of atherosclerosis , which can increase the risk of developing a fusiform aneurysm.

Risk factors for an aneurysm to rupture

Not all aneurysms will rupture. Aneurysm characteristics such as size, location, and growth during follow-up evaluation may affect the risk that an aneurysm will rupture. In addition, medical conditions may influence aneurysm rupture.

Risk factors include:

How Is An Aneurysm Diagnosed

If a patient shows symptoms consistent with a ruptured aneurysm, doctors will performa series of tests to confirm bleeding in the brain. Tests may also be conducted if the symptoms suggest the presence of an unruptured aneurysm.

Diagnostic tests for an aneurysm include:

  • Imaging exams. Computerized tomography and magnetic resonance imaging scans will show doctors whats happening in your brain and can reveal the presence of an aneurysm or bleeding.
  • Spinal tap. An examination of the fluid from your spinal column can indicate that a type of bleeding called a subarachnoid hemorrhage has occurred. This test may be able to detect an aneurysm even if it is not currently bleeding.
  • Cerebral angiogram. This test uses a thin tube to inject dye into an artery. The dye, which is visible on x-rays, then travels to the brain it can indicate the presence of an aneurysm. This test is usually used when other tests are inconclusive.


What Exactly Is A Brain Aneurysm

A brain aneurysm is a bulge in a blood vessel in the brain, according to the Mayo Clinic. Its been described as looking like a berry hanging from a stem. While most aneurysms dont rupture or create health problems, those that do trigger bleeding into the brain result in a hemorrhagic stroke. Strokes can lead to serious consequences and are life-threatening. And if youre experiencing any of the following symptoms, immediately call an ambulance or have someone take you to the ERdont drive yourself.

Eye Or Vision Problems

Cedars-Sinai Medical Center notes that a drooping eyelid or complaints of double vision are possible warning signs of a brain aneurysm pressing against a nerve or beginning to leak blood. A person may mention feeling pain behind or above one eye, or an observer may notice dilation of their pupils. Other early warning signs of a brain aneurysm include blurred vision and photophobia or light sensitivity, notes the Brain Aneurysm Foundation. These signs may precede a rupture by minutes or even weeks.

Some aneurysms will never rupture. However, there are also risk factors that can increase the chance of a ruptured aneurysm.

Some risk factors for rupture are associated with the characteristics of the aneurysm itself. Risk of rupture is raised in brain aneurysms that are:

  • large
  • have grown larger over time
  • located in certain arteries, specifically the posterior communicating arteries and the anterior communicating arteries

Individual factors that increase the risk of rupture include:

  • having a personal or family history of ruptured aneurysms
  • having high blood pressure

What Is An Aneurysm

Abrain aneurysm is a bulge in a blood vessel in the brain caused by a weakening in a wall of the vessel. As blood pressure in the vessel pushes on the weak spot, the vessel wall expands outward like a balloon and is at risk of rupturing or leaking.

When an aneurysm ruptures or leaks, the result is bleeding into the surrounding brain tissue, an event called a hemorrhagic stroke. The bleeding commonly happens at the brains surface, between the brain tissue and the surrounding membranes. The bleeding can cause a damaging loss of oxygen to brain tissue. If fluid builds up in the space where the bleeding occurs, the resulting pressure on brain tissue can also cause damage.

The rupture or leakage of an aneurysm often occurs without warning, and it can quickly turn into a life-threatening situation. Immediate emergency treatment is vital to reduce the risk of permanent, severe neurological damage or death.
