migraine treatment options overview

Overview

A migraine is more than just a bad headache. It is a brain condition that can cause intense throbbing pain, often on one side of the head, along with nausea, vomiting, and extreme sensitivity to light and sound. Migraine attacks can last for hours or even days, and they can interfere with work, school, and daily life. Even though migraines are painful and disruptive, they are not usually dangerous, and there are many ways to manage and treat them.

Yes, migraine is extremely common. Researchers estimate that about 1 in 7 people around the world have migraine. It is one of the most frequent reasons people see a doctor for headache.

Migraine can affect anyone, at any age. It is more common in women and people assigned female at birth, often because of hormonal changes. It also tends to run in families. Children can have migraine too, although the symptoms may look a little different.

Symptoms

Common symptoms

• Throbbing or pulsing headache pain, often on one side of the head
• Pain that gets worse with physical activity
• Nausea or vomiting
• Extreme sensitivity to light, sound, or smells
• Blurred vision or seeing flashing lights, zigzag lines, or blind spots (aura)
• Feeling very tired or weak after the headache goes away

Symptoms in children

• Children may have migraine pain on both sides of the head rather than one side
• They may feel dizzy, stomach pain, or be sick even without a strong headache
• They may become pale, look tired, and want to lie down in a dark, quiet room
• Symptoms may be shorter than in adults, sometimes lasting only a few hours

Symptoms in older adults

• Older adults may have new types of headache that feel different from before
• Aura symptoms may appear without any headache at all, which can be confusing
• They are more likely to have other medical conditions that need to be checked, such as high blood pressure or changes in vision
• Migraine medicines can interact with other medicines, so medical advice is extra important

Causes

Main causes

• Migraine is thought to be caused by changes in how the brain's nerve cells and blood vessels work together.
• A migraine attack may start in the brainstem, which is the area that controls pain signals and sensory information.
• Chemicals in the brain, like serotonin and calcitonin gene-related peptide (CGRP), are likely involved in causing pain and inflammation.
• Many people have what is called a 'migraine threshold.' When certain triggers pile up, they push the brain into a migraine attack.

Risk factors

• Having a close family member with migraine
• Being a woman or assigned female at birth or having hormonal changes around your period, pregnancy, or menopause
• Stress and anxiety
• Skipping meals or not drinking enough fluids
• Irregular sleep or not getting enough sleep
• Bright lights, loud noises, or strong smells
• Weather changes or changes in air pressure
• Certain foods and drinks, such as aged cheese, processed meats, alcohol (especially red wine), or caffeine changes

When to see a doctor

See a doctor urgently if:

• A headache that is sudden and very severe, especially if it is unlike any you have had before
• A headache with fever, stiff neck, confusion, seizures, or passing out
• A headache after a head injury, even if it seems minor
• A headache with weakness, numbness, or trouble speaking

Book a routine appointment if:

• If you have headaches more than once or twice a week, or if they are interfering with your daily life
• If you need pain relief medicine more than two or three times a week
• If your headache pattern changes, such as becoming more frequent or more severe
• If you have never had a migraine before and now are having what feels like migraine symptoms
• If a child is having symptoms that worry you, such as recurrent headaches or dizziness

Diagnosis

Your doctor will start by asking about your headache history in detail. They will want to know how often the headaches happen, how they feel, what makes them worse, and whether you have other symptoms like nausea or sensitivity to light. Keeping a headache diary can help you and your doctor spot patterns and triggers. There is no single test to diagnose migraine; it is mainly based on your symptoms and your clinical history.

Tests that may be done

• A thorough medical and family history
• A physical and neurological examination, where the doctor checks your movement, reflexes, coordination, and senses
• An eye (fundoscopy) exam to check the back of your eyes, sometimes done by a doctor
• If your headaches are unusual or a more serious cause is suspected, the doctor may order an MRI (magnetic resonance imaging) or CT (computed tomography) scan of the brain
• Blood tests may be done to check for other conditions that could cause symptoms similar to migraine

What to expect at your appointment

Your doctor will likely take time to listen to your story and may ask you to fill in a headache diary for a few weeks. They should explain your diagnosis in plain language and talk with you about your treatment options. If your doctor is unsure or wants extra help, they may refer you to a neurologist, which is a specialist in brain and nerve conditions.

Treatment

There is no cure for migraine, but there are many effective ways to treat it. The right treatment plan will depend on how often and how severe your attacks are, and how they affect your life. Most people find they need a combination of self-care, treatments taken during an attack, and sometimes preventive treatments taken regularly. The goal is to reduce how often attacks happen, make them shorter and less painful, and help you live as normally as possible.

Self-care at home

• Rest in a dark, quiet room when an attack starts
• Place a cool cloth or ice pack on your forehead or neck
• Drink small sips of water stay hydrated
• Try relaxation techniques like deep breathing or gently closing your eyes
• Avoid screens, bright lights, loud noise, and strong smells during an attack
• Keep a headache diary to identify and avoid your personal triggers

Medical treatments

Medical treatment for migraine comes in two main types. The first is acute or 'abortive' treatment, taken at the first sign of an attack to stop it from getting worse. These include over-the-counter pain relievers (such as those you can buy from a pharmacy without a prescription) and prescription medicines that work specifically on the pathways involved in migraine, such as medicines that narrow blood vessels and reduce inflammation. Nausea medicines can also help. The second type is preventive treatment, taken regularly (for example, daily) to reduce the frequency and severity of attacks. Options include certain blood pressure medicines, anti-seizure medicines, and newer treatments that target a protein called CGRP thought to play a key role in migraine. Your doctor will work with you to choose what is safest and most appropriate for your situation. Always follow your healthcare provider's advice about which treatment is best for you.

When is surgery considered?

Surgery is very rarely used for migraine. Some people try nerve blocks, where a doctor numbs specific nerves in the head or neck, but this is not usually considered a surgery. Neuromodulation devices, which use tiny amounts of electricity or magnets to change how the brain processes pain, are sometimes used, but these are usually prescribed by specialists. Talk to your doctor about whether any of these approaches could be right for you.

Living with this condition

Living with migraine often means learning to manage triggers and to accept that some days will be harder than others. Try to keep a regular daily routine, including regular sleep, meals, and physical activity. When you feel an attack coming on, act quickly with your treatment plan. Remember that taking pain relief medicine too often can lead to more headaches, so talk to your doctor about how often you use your acute medicines.

Lifestyle tips

• Go to bed and wake up at around the same time every day, even on weekends
• Eat meals at regular times and avoid skipping meals
• Drink plenty of water throughout the day
• Take breaks during long screen time and avoid eye strain
• Practise gentle exercise, like walking or swimming, which can reduce stress and improve sleep
• Build time for relaxation and activities you enjoy

Diet and exercise

A balanced diet with regular meals is important. Some people find that certain foods trigger their migraine, such as aged cheese, chocolate, citrus fruits, alcohol, or foods with monosodium glutamate (MSG). It may help to keep a food diary to see if any patterns show up. Exercise is generally good for migraine, but remember to warm up slowly and stay hydrated. For some people, very intense exercise can trigger an attack, so find a level that feels right for you.

Mental health and emotional wellbeing

Living with migraine can be stressful and frustrating. The unpredictability of attacks can cause anxiety, and chronic pain can take a toll on your mood. It is completely normal to feel this way. If you are feeling anxious, depressed, or overwhelmed, please talk to your healthcare provider. Support groups and talking therapies, such as cognitive behavioural therapy (CBT), can help you cope. If you are having thoughts of self-harm or suicide, reach out for help immediately.

Prevention

Migraine cannot always be completely prevented, but it can often be made less frequent and less severe. The best way to prevent attacks is to understand your triggers and avoid them when you can. For people with frequent or severe attacks, doctors may recommend preventive medicines taken daily. These are not painkillers; they are treatments that help calm the brain's sensitivity to triggers. Your doctor will help you decide if prevention is right for you.

Complications

If left untreated

• Migraine itself is not usually dangerous, but without treatment it can severely affect your quality of life, making it hard to work, study, or spend time with family.
• Using pain relief medicine too often, especially over-the-counter ones, can lead to 'medication-overuse headache', where the pain relief actually causes more headaches.
• Very rarely, a migraine attack can cause a stroke or seizures, but this is exceedingly rare and more likely in people who have other medical conditions.
• Chronic migraine, defined as having 15 or more headache days a month, can develop if migraines are not well managed.

Long-term outlook

If you are reading this, please know that there is good reason to be hopeful. Migraine is a real medical condition, and with the right support and treatment, most people are able to reduce their attacks and live full, active lives. New treatments are being developed all the time. By working with your healthcare provider, keeping a headache diary, and finding what works for you, you can take control of your migraine and not let it define you.
