So what is the cause of a Migraine?..Why do they happen to me?

Even amongst the medical professionals the exact cause of a Migraine attack is not fully understood; but last year researchers located genetic regions which are linked to the onset of a migraine attack.

So the current thinking is that Migraine is a neurological disorder. 

Contrary to myths that surround migraines, they are not caused by mental illness, nor constricted blood vessels, and have nothing in common with chronic headaches caused by stress or sinus problems.

Most researchers occur that those whom have migraine have a sensitive or ‘hyper-excitable’ brain, so that they are much more sensitive to stimuli that would not affect someone not prone to migraine. 

So Migraine attacks do not just happen – they are triggered – everyday factors around a migrainer contribute to the trigger building process to the point where it becomes too much and a migraine is triggered.

These triggers can vary from person to person and attack to attack and don’t always lead to migraine.  A combination of triggers — not a single thing or event — is more likely to set off an attack.   But, working out your triggers is a must for any migraine sufferer – much easy said than done, I know, but understanding your triggers is an important part of your migraine management plan. Once you have identified your triggers, it will be easier for you to avoid them and reduce your chances of having a migraine attack.

Some triggers will jump out at you – others will be hard to find – but keeping a migraine diary can help here.  By recording your activities, pain levels and medication usage.  You should be able to spot (over time) your triggers.

Examples of triggers

Medications
Overuse of over-the-counter medications can cause rebound headaches.
Missed medication doses and certain medications may cause headaches.

Sleep
Changes in sleep patterns eg napping, oversleeping, too little sleep

Hormonal
Estrogen level changes and fluctuations eg Menstrual cycles, birth control pills, hormone replacement therapies, peri-menopause, menopause, ovulation

Environmental
Weather eg Weather and temperature changes, extreme heat or cold, humidity, barometric pressure changes Bright lights eg Bright or glaring lights, fluorescent lighting, flashing lights or screens
Odors/pollution eg Smog, smoke, perfumes, chemical odors
Other eg High altitude, airplane travel

Stress
Periods of high stress,including life changes
Accumulated stress
Reacting quickly and easily to stress
Repressed emotions
Factors related to stress include anxiety, worry, shock,depression, excitement, mental fatigue, loss and grief.
Both “bad stress” and “good stress” can be triggers. Howwe perceive and react to situations can trigger (or prevent) migraines. Other triggers can include unrealistic timelines or expectations of oneself.

Stress letdown
Weekends, vacations, ending a project or stressful task (including presentations, papers, or exams)

Physical
Overexertion / Injuries eg Over-exercising when out of shape, exercising in heat, marathon running
Visual triggers eg eyestrain (if you wear glasses, make sure your prescription is current), bright or glaring lights, fluorescent lighting, flashing lights or computer screens
Becoming tired or fatigued

Dietary Triggers
Food triggers do not necessarily contribute to migraines in all individuals, and particular foods may trigger attacks in certain people only on occasion. Be your own expert by keeping a journal of foods you have eaten before a migraine attack and see whether the removal or reduction of certain foods from your diet improves your headaches.
Skipping meals, fasting, and low blood sugar can also trigger migraines. If you’re unable to follow a normal eating schedule, pack snacks.

Beverages
Chocolate and cocoa. Alcoholic beverages (especially red wine, beer, and sherry). Caffeine (even in small amounts) may be a trigger for some people.

Fruits
Figs, raisins, papayas, avocados (especially if overripe), red plums, overripe bananas.
