What is Migraine

Migraine is a complex neurological disorder characterized by recurrent, moderate-to-severe headaches often accompanied by sensory disturbances, nausea, and extreme sensitivity to light and sound. Unlike a typical tension headache, migraine involves a hypersensitive nervous system that can cause debilitating episodes lasting anywhere from four to 72 hours.

What exactly is a migraine?

While often dismissed as a "bad headache," migraine is a systemic neurological condition. It affects the trigeminal nerve system, the primary pain pathway for the head and face. During an attack, changes in brain chemicals—including serotonin and calcitonin gene-related peptide (CGRP)—cause blood vessels to swell and inflammation to occur, leading to the throbbing, pulsating pain characteristic of a migraine.

How is migraine classified?

Medical experts generally categorize migraine into two primary types based on the presence of sensory warnings:

• Migraine with aura: Occurs when sensory disturbances (such as flashes of light, blind spots, or tingling in the limbs) precede the headache phase.


• Migraine without aura: The most common form, where the headache occurs without the preceding sensory warning signs.

Who is most likely to be affected by migraine?

Migraine is highly prevalent, affecting approximately 12% of the general population worldwide. It is three times more common in women than in men, often due to hormonal fluctuations. While it can begin at any age, the onset most frequently occurs during adolescence or early adulthood. Currently, 223 people with migraine have joined the DiseaseMaps.org community to share their experiences and support one another.

What differentiates migraine from other headaches?

The key factor that distinguishes migraine from other headache disorders is the constellation of associated symptoms. While tension headaches are usually dull and constant, migraine attacks are typically unilateral (one-sided), pulsating, and intensified by physical activity. Many patients also experience "prodrome" symptoms—such as mood changes or food cravings—days before the actual pain begins.

Next steps

• Consult a neurologist or headache specialist to discuss a personalized treatment plan, including both acute and preventive medications.


• Keep a detailed headache diary to track potential triggers like stress, sleep patterns, and diet.
