Migraine
What is Migraine?
A migraine is a neurological condition that causes intense, throbbing headaches. These headaches typically affect one side of the head and can last anywhere from 4 hours to 3 days. Migraine is more than just a bad headache. It involves changes in brain chemistry and blood flow that trigger pain and other symptoms.
Migraines affect roughly 12% of Americans, making them one of the most common neurological conditions. Women are three times more likely to experience migraines than men. The condition often runs in families, suggesting a genetic component. While migraines can start at any age, they typically begin during adolescence or early adulthood.
Many people with migraines experience warning signs called auras before the headache starts. Auras can include visual disturbances like flashing lights or blind spots. Understanding your migraine patterns and triggers is the first step toward managing this condition and improving your quality of life.
Symptoms
- Intense, pulsing or throbbing pain, usually on one side of the head
- Sensitivity to light, sound, and sometimes smells
- Nausea and vomiting
- Visual disturbances like flashing lights, zigzag lines, or temporary blind spots
- Tingling or numbness in the face or hands
- Difficulty concentrating or finding words
- Dizziness or vertigo
- Fatigue and irritability before or after the headache
Some people experience migraines without headaches. They may only have aura symptoms or other neurological signs. Symptoms can vary widely from person to person and even from one migraine attack to another.

Causes and risk factors
Migraines result from complex changes in brain activity and chemistry. During a migraine, brain chemicals like serotonin fluctuate. Blood vessels in the brain may narrow and then widen, triggering inflammation and pain. The exact cause remains under study, but genetics play a significant role. If one or both parents have migraines, you are more likely to develop them too.
Common migraine triggers include hormonal changes, especially in women during menstruation or menopause. Certain foods like aged cheese, processed meats, and alcohol can trigger attacks. Stress, lack of sleep, dehydration, and skipping meals are also frequent culprits. Bright lights, strong smells, and weather changes can set off migraines in some people. Identifying your personal triggers helps you avoid or manage them more effectively.
How it's diagnosed
Diagnosing migraines typically involves a detailed medical history and symptom review. Your doctor will ask about headache frequency, duration, intensity, and any triggers you have noticed. They may perform a neurological exam to rule out other conditions. In most cases, no imaging tests are needed unless your symptoms are unusual or sudden.
Blood tests can sometimes help identify biochemical imbalances that may contribute to migraines. Serotonin levels, for example, can fluctuate during migraine attacks. Some studies show that high serotonin levels may trigger a migraine, while low levels can prolong the attack. Talk to our doctor about testing options that may help identify underlying factors contributing to your migraines.
Treatment options
- Identify and avoid personal triggers like certain foods, stress, or lack of sleep
- Maintain regular sleep schedules and eat balanced meals at consistent times
- Stay hydrated by drinking enough water throughout the day
- Practice stress management techniques like meditation, yoga, or deep breathing
- Use over-the-counter pain relievers like ibuprofen or acetaminophen for mild attacks
- Prescription medications called triptans can stop migraines when they start
- Preventive medications like beta-blockers or antidepressants for frequent migraines
- Newer treatments including CGRP inhibitors that prevent migraine attacks
- Magnesium, riboflavin, and CoQ10 supplements may help some people reduce frequency
- Work with a neurologist or headache specialist for chronic or severe migraines
Frequently asked questions
Migraines are a specific neurological condition that causes intense, throbbing pain usually on one side of the head. They often come with nausea, vomiting, and sensitivity to light and sound. Regular tension headaches cause milder, steady pressure on both sides of the head. Migraines typically last 4 hours to 3 days, while tension headaches may last 30 minutes to several hours.
Blood tests cannot directly diagnose migraines, but they can identify biochemical imbalances that may contribute to attacks. Serotonin levels, for example, fluctuate during migraine episodes. Blood tests can also rule out other conditions that cause headaches, like thyroid problems or vitamin deficiencies. A diagnosis typically relies on your symptom history and a neurological exam.
Common triggers include hormonal changes, stress, lack of sleep, dehydration, and skipping meals. Certain foods like aged cheese, processed meats, chocolate, and alcohol can trigger attacks in some people. Bright lights, strong smells, loud noises, and weather changes also cause migraines. Triggers vary widely from person to person, so keeping a headache diary helps identify your specific patterns.
Yes, migraines often run in families. If one parent has migraines, you have about a 50% chance of developing them. If both parents have migraines, your risk increases to around 75%. Researchers have identified several genes associated with migraine susceptibility. However, genetics alone do not determine whether you will get migraines, as environmental factors and triggers also play important roles.
Prevention starts with identifying and avoiding your personal triggers. Maintain regular sleep and meal schedules, stay hydrated, and manage stress through relaxation techniques. Regular exercise can reduce migraine frequency for many people. If lifestyle changes are not enough, preventive medications like beta-blockers, antidepressants, or CGRP inhibitors can reduce attack frequency. Some people benefit from supplements like magnesium or riboflavin.
See a doctor if you experience frequent or severe headaches that interfere with daily life. Seek immediate care if you have a sudden, severe headache unlike any you have had before. Also get help if your headache comes with fever, stiff neck, confusion, vision loss, or difficulty speaking. These could signal a more serious condition requiring urgent attention.
Treatment depends on migraine frequency and severity. For occasional migraines, over-the-counter pain relievers like ibuprofen or acetaminophen may work. Prescription triptans are more effective for stopping migraines once they start. For frequent migraines, preventive medications like beta-blockers, antidepressants, or newer CGRP inhibitors reduce attack frequency. Your doctor can help you find the right treatment based on your specific situation.
Yes, dietary changes can help many people reduce migraine frequency. Common food triggers include aged cheese, processed meats, chocolate, caffeine, and alcohol. Keeping a food diary helps identify your specific triggers so you can avoid them. Eating regular meals, staying hydrated, and maintaining stable blood sugar levels also help prevent attacks. Some people find that adding magnesium-rich foods reduces migraine frequency.
A migraine aura is a warning sign that occurs before or during a migraine attack. Auras typically involve visual symptoms like flashing lights, zigzag lines, or temporary blind spots. Some people experience tingling or numbness in the face or hands. Auras usually last 20 to 60 minutes and then fade as the headache begins. About 25% of people with migraines experience auras.
Many people experience fewer and less severe migraines as they age. For women, migraines often improve after menopause when hormones stabilize. However, this is not universal, and some people continue to have migraines throughout their lives. Effective treatment and trigger management can significantly reduce migraine impact at any age. Working with a healthcare provider helps you find strategies that work for your situation.
