The Silent Threat: Symptoms of a Brain Aneurysm
A brain aneurysm is a bulging, weakened area in the wall of an artery in the brain. It can grow slowly over time and often goes undetected until it ruptures or causes symptoms.

What is a Brain Aneurysm?
An aneurysm occurs when the walls of a blood vessel weaken and bulge outward, forming a balloon-like sac filled with blood.What does a brain aneurysm feel like? In the brain, these weak spots develop in the arteries that supply oxygen-rich blood to the brain tissue.
As the aneurysm grows larger over time, it becomes increasingly likely to rupture and cause life-threatening bleeding within the brain. Ruptured aneurysms account for approximately 3-5% of all new strokes each year.
The Silent Nature of Brain Aneurysms
Many individuals with unruptured brain aneurysms experience no symptoms at all, which makes these conditions particularly dangerous. Small aneurysms may go undetected for years until they grow larger or rupture.
However, some people may experience certain warning signs or symptoms as the aneurysm expands and puts pressure on surrounding structures within the confined space of the skull.
Symptoms of an Unruptured Brain Aneurysm
While not all unruptured aneurysms produce symptoms, some potential signs and sensations to watch for include:
Localized Headaches
A dull, persistent headache or cluster of headaches may occur on the same side as the aneurysm’s location.
Vision Changes
Aneurysms near the optic nerves can cause double vision, blurred vision, or a temporary loss of vision.
Eye Pain and Drooping Eyelid
Pressure from the aneurysm on the eye muscles or nerves can lead to eye pain and drooping of the eyelid.
Numbness or Weakness
Numbness, tingling, or weakness in one side of the face may occur if the aneurysm compresses certain cranial nerves.
Seizures
In rare cases, an unruptured aneurysm’s mass effect can trigger seizures or convulsions.
Recognizing these potential symptoms and seeking prompt medical attention is crucial to prevent a life-threatening rupture.
Signs of an Aneurysm Rupture
What does a brain aneurysm feel like?A ruptured brain aneurysm is a medical emergency requiring immediate treatment. Patients often experience a sudden, severe headache described as “the worst headache of their life.”
Other common symptoms include:
Severe, Sudden Headache
An explosive, thunderclap headache occurs as blood leaks into the space surrounding the brain.
Nausea and Vomiting
The immense pressure inside the skull often triggers nausea, vomiting, and extreme dizziness.
Vision Disturbances
Double vision, blurred vision, or temporary blindness may result from bleeding near the optic nerves.
Neck Pain and Stiffness
Ruptured blood can irritate the membranes covering the brain and spinal cord, causing neck pain and rigidity.
Confusion or Loss of Consciousness
Bleeding in the brain can lead to confusion, a decreased level of consciousness, or a coma state.
Seizures
Seizures or convulsions are common due to the increased intracranial pressure from the bleed.
Prompt recognition of these symptoms and seeking emergency medical care is crucial to survival and recovery.
Risk Factors for Brain Aneurysms
While brain aneurysms can occur in anyone, certain factors increase an individual’s risk of developing one:
Family History and Genetics
Having a first-degree relative with a brain aneurysm increases one’s risk by a factor of 4 due to genetic predispositions.
Uncontrolled High Blood Pressure
Hypertension, or high blood pressure, puts constant strain on artery walls, weakening them over time.
Smoking
Cigarette smoking introduces toxins that can damage and weaken blood vessel walls.
Heavy Alcohol Consumption
Excessive, long-term alcohol intake has been linked to an increased incidence of brain aneurysms.
Advanced Age
The risk of developing a brain aneurysm increases with age, particularly after 40 years old.
Head Trauma or Injury
Severe head injuries or trauma may potentially contribute to the formation of aneurysms in some individuals.
Certain Medical Conditions
Disorders like polycystic kidney disease, arteriovenous malformations, and connective tissue diseases also elevate aneurysm risks.
Diagnosing Brain Aneurysms
If a brain aneurysm is suspected, doctors may order various imaging tests and scans to confirm the diagnosis:
CT Scan
A computed tomography (CT) scan can detect bleeding from a ruptured aneurysm.
Cerebral Angiogram
This invasive procedure uses a contrast dye injected into the arteries to visualize blood flow patterns and locate aneurysms.
MRI Scan
Magnetic resonance imaging (MRI) provides detailed images to identify the size and location of an unruptured aneurysm.
CTA or MRA
CT angiography (CTA) and magnetic resonance angiography (MRA) are less invasive options to visualize blood vessels.
Early detection greatly improves treatment outcomes and reduces the risk of a life-threatening rupture. Brain aneurysms require close monitoring and a multi-disciplinary approach between neurosurgeons, neurologists, and interventional radiologists.
While brain aneurysms often show no symptoms until a rupture occurs, recognizing potential warning signs can aid in early diagnosis and treatment, potentially saving lives. Seeking prompt medical attention for sudden, severe headaches or concerning neurological symptoms is crucial.
Conclusion
A brain aneurysm can have varied symptoms or may even be asymptomatic. However, when symptoms do occur, they can be alarming and require immediate medical attention. The sensation of a brain aneurysm can differ depending on the location and size of the aneurysm, as well as whether it has ruptured or not.
Common symptoms may include severe headaches, blurred vision, neck pain or stiffness, sensitivity to light, dizziness, and loss of consciousness. In some cases, a ruptured brain aneurysm can cause a sudden and severe headache, often described as the worst headache of one’s life. It is essential to understand that not everyone will experience the same symptoms, and some individuals may not have any symptoms at all until the aneurysm ruptures. Prompt diagnosis and treatment are crucial to prevent complications, such as bleeding or stroke.
If you suspect you or someone you know may be experiencing symptoms of a brain aneurysm, it is vital to seek immediate medical attention. A healthcare professional can perform appropriate tests, such as imaging scans, and determine the best course of action. Remember, early detection and intervention can greatly improve the prognosis and increase the chances of a successful recovery from a brain aneurysm.
