A migraine is more than just a bad headache. What can trigger a migraine and what effective treatments are available?

Anyone who's had a migraine knows how debilitating it can be. It begins with your head throbbing from the inside, the pain spreading like frozen iron from behind one eye to the next. You keep your head down, avoiding bright lights and loud sounds. Nausea begins to rise. If you're lucky you can retreat to bed before it gets any worse, where the migraine pins you down for anything between a few hours and a couple of days.

Migraine is not just a bad headache. It can debilitate you in ways that head pain cannot. For many, those with chronic migraine, more than half of your days each month are spent in this state.

Migraine is caused by a hypersensitive brain

Migraine is a disease of hypersensitivity: The migraine brain has abnormally sensitive neuronal connections.

Compared to people who don't get migraines, this leaves migraineurs more likely to respond to small changes in the environment, which can result in headaches or more serious migraine attacks.

Migraine attacks are thought to originate from abnormal electrical excitability in sensory neurons in the meninges, layers of membrane that protect the brain.

When sensitized, these neurons send signals to the brain which trigger headache pain, photophobia, and other migraine symptoms. These neurons are also close to blood vessels, which is why headaches can feel like they pulse along with your heartbeat.

According to Paul Durham, a migraine researcher at Missouri State University, US, migraine is a disease which primarily affects the brain, but also involves the whole body.

"Other systems such as the immune, digestive and cardiovascular system contribute to migraine. That means if you only target one aspect of migraine with analgesics [pain-relief], then it is not likely to alleviate all symptoms and improve the patient's quality of life," he said.

What triggers migraine?

There are a huge range of migraine triggers and each person's triggers can differ from the next. The most common triggers are:

Bright lights and loud sounds. Strong smells like perfume, smoke, or certain smelly foods. Lack of sleep, poor quality sleep, or jet lag. Hunger or dehydration. Too much caffeine. Alcohol, especially red wine. Hormone fluctuations, such as before or during periods, pregnancy, or menopause. Foods and diet, especially diets containing ultra-processed foods and processed sugars. Stress.

Durham said that stress is the key binding factor here:

"These factors promote a hyper-excitable nervous system that is more susceptible to migraine triggers. Stress is a major factor in modern society," he said.

Ways to help alleviate migraine symptoms

There are ways you can help to alleviate the severity of a migraine, or prevent a headache becoming a full-blown migraine.

Drinking plenty of fluids or placing an icepack on your forehead can help, as can resting in a quiet, dark room to ease environmental stressors.

Many patients learn to get migraine relief from cognitive behavioural therapy (CBT). It's unlikely to treat the disease, but it can teach you thought actions to cope with pain and understand migraine triggers.

There are claims that mindfulness can also help, however studies are finding little evidence it has a robust impact on headache or migraine symptoms in the long run.

How do you treat migraine?

Here are some of the most clinically successful migraine medications:

Calcitonin gene-related peptide (CGRP) monoclonal antibodies: These new migraine medications block the action of a protein called CGRP. CGRP plays an important role in the development of migraine symptoms, sensitizing neurons in the meninges. Triptans: A class of medications which bind to certain types of serotonin receptors in the body and causes pain-relieving effects. Analgesics like paracetamol or aspirin can be effective in reducing headache pain, but don't tend to help reducing chronic migraine symptoms.

The evidence for CGRP antibodies and Triptans as migraine treatments is particularly robust, with patients having dramatic improvements of life quality after taking the drugs. However, the drugs don't work in all patients, meaning not all patients can get migraine relief from medication.

Another issue is that treatments tend to focus on alleviating headache pain, which means other symptoms like nausea, light sensitivity and tiredness can remain.

Migraine treatments in development

Researchers are working hard to solve these treatment gaps and there are promising candidates being investigated:

Neuromodulation devices: e-TNS (external trigeminal nerve stimulation) is a treatment which gives low power electrical stimulation to facial nerves. Clinical trials are showing clinical success in treating migraine, but it is not yet approved for patient use. Oxytocin: oxytocin hormonal nasal sprays could be effective and safe at reducing migraine incidence, especially in women. Certain foods or dietary supplementation treatments: Paul Durham's research shows grape seed extract, cacao, or chicken broth can help reduce migraine incidence in some people.

"I don't think nutraceuticals should ever replace medications, but they could provide another option for managing migraine. I like what Hippocrates said: 'Let food by thy medicine', " he said.

For the time being, these latest approaches have only been tested on small numbers of patients, meaning they currently lack sufficient evidence to be recommended to patients. However, all three candidates look promising, and clinical testing is underway to see if could be used as safe and effective migraine treatments.
