Causes Of An Aneurysm

Are there warning signs for brain aneurysms?

Aneurysms may arise suddenly after severe trauma, but they more often result from the gradual weakening of arteries throughout a persons life. Certain conditions or behaviors increase your risk of developing an aneurysm:

In the case of a suspected brain aneurysm, doctors may also perform a cerebrospinal fluid analysis. In a cerebrospinal fluid analysis, cerebrospinal fluid is gathered through a lumbar puncture and then tested to detect the presence of bleeding.

Warning Signs Of A Brain Aneurysm

A brain aneurysm is a balloon-like bulge in a blood vessel in the brain.

Brain aneurysms can occur in anyone but are most common in adults between the ages of 40 and 60.

Most brain aneurysms do not cause symptoms.

However, some brain aneurysms can rupture, causing bleeding in the brain .

A ruptured brain aneurysm is a medical emergency that requires immediate treatment.

Ways To Spot A Brain Aneurysm Before It’s Too Late

These things are straight-up terrifying.

Here’s a stat that’s sure to keep you up at night: Currently, anywhere from three to five million people in the U.S. are walking around with brain aneurysms, according to the American Stroke Association.

If you’re thinking “what the heck is a brain aneurysm?” it’s basically a blood vessel in your brain that’s on the verge of an explosion. Put simply, its a weakness that starts to occur in a blood vessel inside the brain or right outside it, says David Putrino, Ph.D., director of rehabilitation innovation at Mount Sinai Hospital in New York City. As blood flows through this vessel in the brain, the weak point starts to bulge out like a balloon, and it looks like a berry hanging off a branch.

Luckily, most aneurysms dont ever rupture or cause any symptoms. But when they do, things get really serious, really fast. According to the Brain Aneurysm Foundation, about 40 percent of ruptured brain aneurysms lead to death. Others can cause severe brain damage and neurological problems if not treated immediately. Time is the most important factor in terms of surviving and having less neurological damage from a rupture, says Putrino.

Here are the brain aneurysm symptoms you need to know about so you can act quickly and keep yourself healthy.

What Is A Cerebral Aneurysm

A cerebral aneurysm is a weak or thin spot on an artery in the brain that balloons or bulges out and fills with blood. The bulging aneurysm can put pressure on the nerves or brain tissue. It may also burst or rupture, spilling blood into the surrounding tissue . A ruptured aneurysm can cause serious health problems such as hemorrhagic stroke, brain damage, coma, and even death.

Some cerebral aneurysms, particularly those that are very small, do not bleed or cause other problems. These types of aneurysms are usually detected during imaging tests for other medical conditions. Cerebral aneurysms can occur anywhere in the brain, but most form in the major arteries along the base of the skull.

Brain aneurysms can occur in anyone and at any age. They are most common in adults between the ages of 30 and 60 and are more common in women than in men. People with certain inherited disorders are also at higher risk.

All cerebral aneurysms have the potential to rupture and cause bleeding within the brain or surrounding area. Approximately 30,000 Americans per year suffer a brain aneurysm rupture. Much less is known about how many people have cerebral aneurysms, since they dont always cause symptoms. There are no proven statistics but a consensus of scientific papers indicate that between 3 and 5 percent of Americans may have an aneurysm in their lifetime.

How Is A Brain Aneurysm Diagnosed

What are the Warning Signs of a Brain Aneurysm?

Unless an aneurysm ruptures, it may be difficult to diagnose. Doctors can use certain tests to locate brain aneurysms in people who have a family history of the condition, risk factors, and inherited aneurysm-related health issues.

Its also possible for an aneurysm to be detected during tests for unrelated health conditions, such as headaches or seizures.

Diagnosis of brain aneurysms relies on imaging that can visualize brain tissues and arteries, which may detect the presence of an aneurysm.

Imaging tests may include one or more of the following:

How Can A Brain Aneurysm Growth Or New Aneurysm Formation Be Prevented

Once an aneurysm is found, it is not expected to resolve on its own. However, aneurysm growth, change, risk of aneurysm rupture, or new aneurysm formation can be reduced by having a healthy lifestyle. Steps you can take include:

  • Exercise regularly without excessive heavy lifting.
  • Eat a balanced diet.
  • Get help for alcohol or drug use disorder and dont use cocaine or other stimulant drugs.
  • Control high blood pressure with medications and lifestyle changes.

Be Aware Of These Brain Aneurysm Symptoms

You can indeed have a brain aneurysm and not know it, says , a neurosurgeon with the Cerebrovascular Center at the Cleveland Clinic in Ohio. If the aneurysm has not ruptured, it typically causes no symptoms, according to the Brain Aneurysm Foundation.

See a doctor immediately if you have any of these symptoms, Dr. Bain says, which may mean an aneurysm is pressing on your brain or nerves:

  • Headache in one spot
  • Pain above or behind your eye
  • Dilated pupils
  • Weakness and numbness
  • Slurred speech

If the aneurysm ruptures and blood spills into the space around your brain, you could have what you’d consider the worst headache of your life.

Some patients describe it as being hit in the back of a head by a sledgehammer, Bain says. Other symptoms include those that Mureddu experienced: nausea, vomiting, and sudden blurred or double vision, as well as a stiff neck, dizziness, sensitivity to light, and drooping eyelids. You also could have a stroke, notes the National Heart, Lung, and Blood Institute.

If the aneurysm doesn’t rupture, your doctor may recommend treatment or careful monitoring. Once it ruptures, it should be treated with either open surgery or endovascular surgery, which is done within the blood vessels.

Weve taken a page out of the heart doctors book, Bain says. In some cases, a surgeon can thread a catheter through the femoral artery to the brain and place coils to seal off the aneurysm.

Likewise, are there warning signs of a brain aneurysm?

Warning Signs and SymptomsWhile most brain aneurysms cause no symptoms, individuals with large brain aneurysms that have not yet ruptured may experience severe localized headaches, blurred vision, changes in speech and neck pain, depending on the size and location of the aneurysm. Sudden blurred or double vision.

Secondly, do you die instantly from a brain aneurysm? Ruptured brain aneurysms are fatal in about 50% of cases. Of those who survive, about 66% suffer some permanent neurological deficit. Approximately 15% of people with a ruptured aneurysm die before reaching the hospital. Most aneurysms develop after the age of 40.

Keeping this in consideration, can you get a brain aneurysm from stress?

Although the exact cause of an aneurysm is unclear, certain factors contribute to the condition. For example, damaged tissue in the arteries can play a role. This stress can damage the arteries because of the increased pressure.

Who is at risk for a brain aneurysm?

Brain aneurysms can occur in anyone and at any age. They are most common in adults between the ages of 30 and 60 and are more common in women than in men. People with certain inherited disorders are also at higher risk.

Eye Or Vision Problems

The warning signs of a brain aneurysm

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.

What Does A Brain Aneurysm Look Like

Brain aneurysms can take several forms. About 90 percent are saccular, or berry, aneurysms. This type forms a sac outside the artery that looks like a berry attached to a vine.

A fusiform aneurysm is a rarer type of aneurysm that affects a longer section of the artery wall, causing the artery to bulge all the way around. Its estimated that

Brain aneurysms can affect anyone. However, some factors can increase your risk.

There are different risk factors for aneurysm development and rupture.

Are There Warning Signs Before An Aneurysm How To Know Your Risk

  • There aren’t usually warning signs before an aneurysm ruptures.
  • An estimated 50% to 80% of aneurysms never rupture, but when they do, they are very dangerous and are accompanied by extreme pain in the head, chest, or abdomen.
  • Knowing your risk factors for an aneurysm can help catch it before it ruptures these include high blood pressure, frequent smoking, or genetics.
  • This article was reviewed by Jason R. McKnight, MD, MS, a family medicine physician and clinical assistant professor at Texas A& M College of Medicine.
  • This story is part of Insider’s guide on High Blood Pressure.

If your artery walls weaken and balloon, you are experiencing an aneurysm. This widening of blood vessels typically happens in the brain , the abdomen , or the chest .

An aneurysm is dangerous if it ruptures. About 40% of ruptured brain aneurysms and roughly 50% of ruptured abdominal aortic aneurysms are fatal. And about 66% of those who survive a ruptured brain aneurysm will have some permanent neurological deficit.

However, it is common for people to live with aneurysms, and an estimated 50% to 80% of aneurysms never rupture. Here’s what you need to know about the warning signs of an aneurysm and what you can do to catch it before it ruptures.

What Is The Outlook For Someone With A Brain Aneurysm

Not all aneurysms will rupture. According to the Brain Aneurysm Foundation, about 6.5 million people in the United States have brain aneurysms that havent ruptured. In fact, an estimated 50 to 80 percent of all brain aneurysms never rupture in a persons lifetime.

According to the National Institute of Neurological Disorders and Stroke, about 50 percent of individuals dying within 3 months.

Because of this, its important to be vigilant in monitoring existing aneurysms as well as taking steps to prevent them from rupturing. Its possible that your doctor may recommend surgical treatment for aneurysms that are large or at an increased risk of rupturing.

If you notice signs of rupture, its vital to seek immediate medical care to increase your chance of survival and recovery.

After a rupture, recovery can take weeks to months, and its likely that youll need physical, occupational, or speech therapy during this time. Its also possible that you may never fully recover, depending on the severity of the damage.

Brain Aneurysm: 4 Things You Need To Know

Pin on Health

    When part of a blood vessel in your brain bulges, or balloons, it’s called an aneurysm. Every brain aneurysm is unique in location, shape and size. These particulars guide your doctor in determining how and whether to treat a brain aneurysm.

    Neurosurgeon Judy Huang, M.D., of the Johns Hopkins Department of Neurosurgery, provides insight into some of the most common questions behind brain aneurysm diagnosis and treatment.

    Symptoms Of A Brain Aneurysm

    • Headache

      Possibly the most well-known effect of a brain aneurysm is a severe headache. Headaches can happen for many reasons, so it may seem a little dramatic to assume that a minor one is because of an aneurysm. However, two types of headaches can result from them. The first is called a sentinel headache. These headaches are often described as unbearable and cause excruciating pain. Sentinel headaches are medical emergencies. The other type of headache caused by a brain aneurysm is more of a continuous headache that is ongoing for a couple of weeks. This type of headache isnt an indicator of a rupture, but aneurysms commonly cause this type of pain.

    • Vision

      A brain aneurysm can cause a significant impact on vision by causing pressure to the optic nerve in the brain. One type of vision impairment, called a nasal quadrantanopia, causes vision loss when the aneurysm causes excess stress on an optic nerve. The other cause of vision loss is San Antonio.

    What Is An Aneurysm

    An aneurysm occurs when pressure causes a weak point in a blood vessel to balloon. The small sac or bulge created is known as an aneurysm.

    When people talk about aneurysms, they are most often referring to brain aneurysms, also called cerebral or intracranial aneurysms, but aneurysms can also form in the abdomen or, more rarely, in the chest.

    The danger is that the brain aneurysm will burst. Ruptured aneurysms are fatal about half of the time, and more than half of those who survive suffer permanent brain damage.

    Not all brain aneurysms rupture. In fact, about 1 in 50 people in the United States has an unruptured aneurysm, and 50-80% of aneurysms dont burst during a persons life.

    Early and accurate diagnosis of a brain aneurysm is crucial. Unruptured aneurysms can often be treated before they burst. In the case of a ruptured aneurysm, immediate care may save a persons life and lessen brain damage.

    What Can I Do To Reduce My Risk Of Having Another Brain Aneurysm

    Taking care of your overall health is the best thing you can do to prevent future aneurysms. Steps you can take include:

    • Eat a healthy diet, limit caffeine and avoid stimulant drugs.
    • Quit smoking.
    • Manage conditions that contribute to high blood pressure.
    • Talk to your healthcare provider about lifestyle changes you can make and medications that may help.


    A sudden, severe headache with or without stroke symptoms could be a sign of a brain aneurysm. A ruptured brain aneurysm is a serious, life-threatening condition that needs immediate medical attention and emergency treatment. If you have an unruptured brain aneurysm, talk with your healthcare provider about the risks and benefits of different treatment and management options.
