How to Tell if a Migraine or Brain Aneurysm

It is crucial to seek immediate medical attention if you experience any severe or sudden headaches, as it can be difficult for a person to determine on their own whether the symptoms indicate a migraine or a brain aneurysm. A brain aneurysm is a bulging, weakened area in the wall of an artery in the brain, while a migraine is a neurological condition characterized by intense headaches, often accompanied by other symptoms.

Here are some signs and symptoms to consider:

1. Headache Intensity: Brain aneurysm headaches are typically sudden and extremely severe, often described as the "worst headache of my life." Migraine headaches, while severe, usually build gradually and reach peak intensity over time.

2. Sudden Onset: Brain aneurysm headaches often come on abruptly and without warning, like a thunderclap. Migraines, on the other hand, may be preceded by certain triggers or prodrome symptoms, such as visual disturbances or sensory changes.

3. Nausea and Vomiting: Severe nausea and vomiting are more common with migraines. While brain aneurysms can also cause these symptoms, they are less frequently reported.

4. Headache Location: Brain aneurysm headaches are typically felt behind or above one eye. Migraine headaches can occur on one or both sides of the head and can vary in location.

5. Neurological Deficits: Brain aneurysms can cause neurological deficits, such as vision changes, speech difficulties, weakness or paralysis on one side of the body, and loss of consciousness. Migraines typically do not cause these symptoms.

6. Duration: Brain aneurysm headaches can last for several days, while migraine headaches usually resolve within hours or a few days.

7. Sensitivity to Light and Sound: Sensitivity to light (photophobia) and sound (phonophobia) are common symptoms of migraines, but they may also occur with brain aneurysms.

8. Aura: Migraines often have a warning sign known as an aura, which may include visual disturbances, such as flashing lights or zig-zag lines. Brain aneurysms do not cause auras.

It's important to remember that not all headaches are migraines or caused by brain aneurysms. However, if you experience any sudden or severe headaches, especially accompanied by other concerning symptoms, it's crucial to seek immediate medical evaluation to determine the cause and receive appropriate treatment. A doctor can perform tests and imaging studies, such as an MRI or CT scan, to confirm or rule out the presence of a brain aneurysm or other medical conditions.
