What Is A Migrane?

Migraine is not just a bad headache. It is a complex neurological condition that affects over one billion people worldwide, according to the World Health Organization. A migraine attack involves distinct phases and can include symptoms like severe throbbing pain, nausea, vomiting, and extreme sensitivity to light and sound. The pain is often on one side of the head and can last from four to 72 hours if untreated.

What Exactly Is a Migraine?

A migraine is a brain disorder. It involves abnormal brain activity that temporarily affects nerve signals, chemicals, and blood flow in the brain. The exact cause is still being studied, but research shows that genetics play a major role. If one of your parents has migraines, you have about a 50 percent chance of having them too.

Migraines are often misunderstood as just severe headaches. But the headache itself is only one part of the attack. Many people experience warning signs hours or even days before the pain starts. These can include food cravings, mood changes, stiff neck, and frequent yawning. About one in four people with migraine also experience an “aura” — visual disturbances like flashing lights or blind spots that happen just before or during the headache phase.

What Are the Phases of a Migraine Attack?

Migraine attacks have four distinct phases. Not everyone experiences all four, but knowing them helps you recognize an attack early. The phases are prodrome, aura, headache, and postdrome.

The prodrome phase happens 24 to 48 hours before the headache. You might feel tired, crave certain foods, or feel irritable. The aura phase involves temporary nervous system symptoms, most commonly visual changes. This usually lasts 5 to 60 minutes. The headache phase is the pain stage, but it also includes nausea, sensitivity to light and sound, and difficulty concentrating. The postdrome phase follows the headache and can leave you feeling exhausted, confused, or even euphoric for a day or two.

What Triggers a Migraine?

Triggers vary widely from person to person. Common triggers include stress, hormonal changes, sleep changes, weather changes, and certain foods or drinks. The American Migraine Foundation reports that stress is the most commonly reported trigger, affecting about 80 percent of people with migraine.

Hormonal changes are especially relevant for women. Many women notice migraines around their menstrual period, during pregnancy, or during perimenopause. This is because estrogen levels fluctuate. Other triggers include skipped meals, dehydration, bright lights, loud sounds, strong smells, and certain foods like aged cheese, processed meats, and alcohol — especially red wine.

One thing worth noting: triggers are not causes. A trigger does not give you migraine disease. It just sets off an attack in someone who already has the condition. This is a common misunderstanding. If you avoid all triggers you still have migraine — you just have fewer attacks.

How Is Migraine Diagnosed?

There is no blood test or scan that can diagnose migraine. Diagnosis is based on your history and symptoms. A neurologist will ask about your headache patterns, family history, and how attacks affect your daily life. They may use the ICHD-3 criteria from the International Headache Society to confirm the diagnosis.

The criteria for migraine without aura include having at least five attacks that last 4 to 72 hours. The headache must have at least two of these features: one-sided location, pulsating quality, moderate to severe pain, or aggravation by routine physical activity. During the headache you must also have nausea or vomiting, or sensitivity to light and sound.

Your doctor may also order imaging like an MRI or CT scan if your headaches are unusual or if neurological symptoms are new. This is mainly to rule out other causes like a tumor or stroke. Most people with migraine do not need imaging.

What Treatments Actually Work for Migraine?

Treatment falls into two categories: acute and preventive. Acute treatments stop an attack once it starts. Preventive treatments reduce how often attacks happen and how severe they are.

For acute treatment, the most common options are over-the-counter pain relievers like ibuprofen or naproxen, and prescription medications called triptans. Triptans like sumatriptan and rizatriptan work by narrowing blood vessels and blocking pain pathways in the brain. Research shows that triptans are effective for about 60 to 80 percent of people with migraine. Newer acute options include gepants like ubrogepant and ditans like lasmiditan, which work differently and may be better for people who cannot take triptans.

Preventive treatments are taken daily or monthly. Older options include beta-blockers, antidepressants, and anticonvulsants. Newer options include CGRP monoclonal antibodies, which are injections taken monthly or quarterly. The American Headache Society reports that CGRP inhibitors reduce migraine days by about 50 percent in many people. Botox injections are also FDA-approved for chronic migraine — defined as 15 or more headache days per month.

• Acute treatments: triptans, NSAIDs, gepants, ditans, anti-nausea medications
• Preventive treatments: beta-blockers, CGRP antibodies, Botox, antidepressants, anticonvulsants
• Non-drug options: cognitive behavioral therapy, magnesium supplements, riboflavin, coenzyme Q10

What About Migraine Myths and Misconceptions?

One of the most persistent myths is that migraine is just a bad headache. This minimizes a serious neurological condition. Another common myth is that migraine only affects women. While women are three times more likely to have migraine than men, men also get migraines. Children get them too.

Some people believe that migraine can be cured by avoiding triggers. This is not true. Avoiding triggers can reduce attack frequency, but it does not cure the underlying condition. Migraine is a chronic disease with no cure. Treatment is about management, not elimination.

Another widespread claim is that caffeine always makes migraines worse. This is not accurate for everyone. For some people, caffeine can actually help stop an attack when taken early, especially when combined with pain relievers. The problem is that daily heavy caffeine use can lead to rebound headaches. The key is knowing your own response.

When Should You See a Doctor About Migraine?

You should see a doctor if headaches interfere with your daily life. If you miss work, school, or time with family because of headaches, that is a sign you need help. You should also see a doctor if you have more than four headache days per month, or if your headaches are getting worse over time.

Seek emergency care if you have a sudden, severe headache unlike any you have had before. Also seek care if you have a headache with fever, stiff neck, confusion, seizures, double vision, or weakness on one side of your body. These could be signs of a more serious condition like meningitis, stroke, or a brain aneurysm.

Many people with migraine do not get the help they need. The CDC reports that only about half of people with migraine have been diagnosed by a doctor. If you think you have migraine, a neurologist or headache specialist can help you find a treatment plan that works.
