Headache: the main symptom

People who have survived a brain aneurysm report that one of the main signs before the rupture was an extremely intense and sudden headache. Differentiating an aneurysm from a migraine can be challenging, but some characteristics may indicate a higher risk:

Severe headache, described as the worst headache of your life;
Sudden onset and no history of migraines;
Accompanied by other neurological symptoms.
If you or someone close to you has an unusual headache, seek medical attention immediately.

Other symptoms of a brain aneurysm

In addition to a sudden, severe headache, other signs may indicate an aneurysm. Watch for the following symptoms:

– Sudden drooping of the eyelids
– Double or blurred vision
– Unexpected seizures
– Pain in one eye
– Unexplained nausea and vomiting
– Stiff neck
– Extreme sensitivity to light
– Numbness in part of the face
– Ringing or loud noises in the head
– Momentary loss of consciousness

If someone has one or more of these symptoms, take them to the hospital immediately.

Risk factors for brain aneurysm

Some people are more likely to develop a brain aneurysm due to genetic factors or lifestyle habits. The main risk factors include:

– High blood pressure
– Family history of brain aneurysm
– Smoking
– Excessive alcohol consumption
– Use of drugs such as cocaine
– High cholesterol and cardiovascular disease
– Genetic diseases that weaken blood vessels

If you have one or more of these risk factors, talk to your doctor about preventive measures.

How is the diagnosis made?

To confirm the presence of an aneurysm, doctors use imaging tests such as:

– Computed tomography (CT): Detects bleeding in the brain;
– Magnetic resonance imaging (MRI): Shows details of blood vessels;
– Cerebral angiography: More accurate exam to visualize aneurysms.

If an aneurysm is suspected, the doctor will indicate the best exam for each case.

Available treatments

Treatment varies according to the size, location and risk of rupture of the aneurysm. Options include:

1. Monitoring

When the aneurysm is small and low risk, the doctor may only recommend regular monitoring to monitor its progress.

2. Surgery

Surgical clamping: Performed through an opening in the skull to close the aneurysm with a clip.
Endovascular embolization: Minimally invasive procedure that inserts coils into the aneurysm to block blood flow.

The type of intervention is defined by the neurosurgeon according to the patient’s condition.

How to prevent a brain aneurysm?

Although it is not always possible to prevent an aneurysm, some measures help reduce the risks:

– Control blood pressure with a balanced diet and exercise
– Avoid smoking and excessive alcohol consumption
– Reduce stress and seek moments of relaxation
– Keep medical exams up to date, especially if there is a family history
