A migraine is more than a severe headache, but its exact cause remains unclear. Genetics and changes in brain activity often play a role, while factors such as stress or disrupted sleep may trigger an attack in some people. Here is a closer look at the causes of migraines:
Altered Brain Signaling
Researchers link migraine to changes in how the brain sends and processes signals. Nerve cells become more excitable, and this heightened activity can spread across the brain in a wave that alters blood flow and chemical balance. Fluctuations in serotonin, a chemical messenger, appear to play a part, though the full picture remains under study. This signaling change explains why a migraine is different from an ordinary headache. The trigeminal nerve, which carries sensation from the face and head, releases substances that inflame nearby blood vessels; that inflammation drives the throbbing pain people often report.
Inherited Migraine Risk
Migraine tends to run in families, and your genetic makeup can increase your possibility of developing it. If one or both parents experience migraine, your own risk increases, though inheritance does not guarantee that you will have attacks. Multiple genes appear to influence how sensitive your nervous system is to triggers.
A detailed family history gives your specialist context, and it can speed up an accurate diagnosis. Here are a few points worth sharing during your consultation:
- Relatives with migraine: Note which family members have attacks and how often, as patterns often repeat across generations.
- Age of onset: Mention when your migraines began because early or sudden onset can guide testing decisions.
- Response to treatment: Describe what worked or failed for relatives, since some medication responses have a genetic component.
Hormonal Changes
Hormones influence migraine frequency and intensity. Shifts in estrogen levels around menstruation, pregnancy, and menopause often line up with attacks, and people may notice a predictable rhythm. The relationship works in both directions, and rising or falling estrogen can each act as a trigger. Some individuals report fewer migraines during pregnancy, while others see attacks worsen; responses vary from person to person. A specialist who understands this variability can time treatments to match your hormonal pattern, which is a key part of a tailored plan.
Environmental and Everyday Triggers
Daily habits and surroundings can set off a migraine, and identifying these triggers is a fundamental step toward control. Triggers differ widely between individuals, so what affects one person may not affect another. Keeping a log helps you identify the specific factors that precede your attacks. Common everyday and environmental triggers include the following:
- Sleep changes: Too little or too much sleep can disrupt the brain’s rhythm and prompt an attack.
- Skipped meals: Low blood sugar from missed meals often precedes migraine for some people.
- Stress: Rising tension, or the sudden drop after a stressful period, may trigger attacks.
- Sensory input: Bright lights, loud sounds, and strong smells frequently contribute.
- Weather shifts: Changes in barometric pressure and temperature can influence attacks.
