A migraine is a headache that involves throbbing or pulsing on one side of the head. It is very different from other headaches, which are typically characterized by duller, more widespread pain. The International Headache distinguishes a migraine by the length of the attacks (at least five over a period of time that depends on the individual, plus pain that lasts from four to 72 hours.) Experts have named four distinct stages of migraine, though not every migraine sufferer goes through them all. The stages are:
According to the National Library of Medicine, Migraines usually appear for the first time between the ages of 10 and 45. They are three times more common among women than men, according to the Migraine Research Foundation. (Estrogen may be a culprit.) Occasionally, the NLM says, they may become less frequent during pregnancy. According to the National Headache Foundation, 37 million Americans suffer from migraines.
According to the National Institutes of Health (NIH), a migraine headache is caused by abnormal brain activity. Most experts believe that the attack involves constriction/dilation of blood vessels, neural pathways, and brain chemicals, and that changes in those areas affect blood flow in the brain. The exact chain of events leading to migraine still isn’t entirely clear, and the brain activity can be triggered by a number of causes.
Experts believe that there are a number of triggers for migraine, including caffeine withdrawal, the hormonal changes that accompany menstruation or the use of birth control pills; loud noises or bright lights; odors (including perfumes); stress, anxiety, and drinking alcohol.
Migraines can also be triggered by certain foods. The most common food triggers include chocolate; food with monosodium glutamate (MSG); foods with tyramine (red wine, aged cheese, smoked fish); fruit (avocado, banana, citrus); meats with nitrates, including bacon and cured meats; and pickled or marinated foods.
The following are risk factors for migraines:
A physician can often diagnose migraines through a review of symptoms and family history. If migraines suddenly become worse, doctors may perform the following tests to rule out a more serious cause for the pain such as bleeding in the brain, tumors, and other serious conditions:
Because everybody experiences migraines differently, symptoms may not be the same for all patients. Some patients experience limited symptoms surrounding the attack and extreme pain during the attack, and others experience noticeable symptoms leading up to the attack and after the attack, but experience less intense pain during the attack period.
Often, symptoms of migraines depend on the stage that the migraine is in. Not all migraine sufferers experience the same progression. If you are experiencing a combination of the following symptoms (even if they are out of order) you may be experiencing a migraine:
Prodrome. This is the period of time that occurs around 24 hours before a migraine. Symptoms may include:
Aura. This is the period right before the characteristic head pain of a migraine begins. Symptoms can include:
The attack. The actual migraine attack can last anywhere from four to 72 hours. Symptoms include:
Postdrome. This is the “hang-over” phase of the migraine. Symptoms include:
After a person has a number of migraines, the condition can build up to the point where he or she has a daily migraine. (The Migraine Research Foundation says that about 14 million people have headaches for at least 15 days per month). Health experts emphasize that medicine is important for controlling the condition. But the Migraine Research Foundation calls the condition “chronic,” and another organization, the Migraine Trust, says there is no cure. Steps can be taken to manage symptoms and occasionally prevent attacks.
Lifestyle changes can help migraine patients make their conditions less burdensome.
The following tips may help you reduce your migraine frequency:
Some doctors choose to screen patients for migraines with a short questionnaire that asks if the patient experiences headaches, and if yes, how severe are they and how long do they last? This questionnaire has been proven to be effective in diagnosing migraines that would have otherwise gone unnoticed. If a doctor suspects a patient is suffering from migraines, he or she may conduct one or several diagnostic tests.
If you have inherited a susceptibility to migraines, there aren’t too many things you can do to prevent migraines. But you can make lifestyle changes that will help. The most important one, according to the American College of Physicians (PCP), is to learn how to manage stress. They suggest getting enough sleep and exercise, as well as regular meals. Avoid environmental triggers that have caused you headaches, including bright light and smoke. You should also quit smoking.
According to the American College of Physicians (ACP), you should keep a headache journal. This journal, the ACP says, should detail the date of your migraine, how long it lasts, an intensity of pain scale from 1-10, preceding symptoms, triggers, relief measures and relief (whether it’s complete or moderate, and how much time it takes to get relief). This will help you get a handle on your migraine patterns and enable you to manage any preceding symptoms. For example, you could avoid red wine if you realize that’s a trigger for you. Share the information from your journal with your doctor so he or she can tailor your medication to your patterns.
Additionally, migraine sufferers should figure out their food triggers. The headache journal mentioned above can help you, although it may take a while to discover which foods are at fault. For example, the ACP cites the case of a patient thinking that having a chocolate bar might be a food trigger. But merely the desire for it might be a signal that a migraine is imminent. Chocolate isn’t a trigger for everyone, the ACP points out. Some sufferers actually benefit from the caffeine in it, the ACP says.
Certain medications can help reduce migraine frequency and severity. These include:
Propanol (Inderal) This beta blocker medication can help prevent attacks in some patients who are having frequent migraines or severe, long-lasting attacks. Propranolol is a beta blocker medication, which is helpful in preventing migraine attacks in some patients. If a patient is having frequent attacks or severe, long-lasting attacks, it may be of help in cutting down the frequency of the attacks. As with all prescription drugs, this should be taken only under a doctor’s supervision.
Side effects of propanol include:
Timolol (Blocadren) is a beta blocker that affects the blood flow through arteries and veins. Experts believe that some migraines are caused by the narrowing of veins and arteries, restricting blood flow and causing the condition.
Side effects include:
Selective serotonin receptor antagonists. This is a class of medications that works by reducing pain transmission signals to the brain and by stimulating serotonin receptors in the brain that can affect blood flow. Many selective serotonin receptor antagonists come in injectable forms.
Side effects of selective serotonin receptor antagonists vary from medication to medication, and may include:
Botox (botulinum toxin), though primarily known as a cosmetic treatment, has been in use for years as a treatment for chronic migraine. It works by temporarily deadening nerve endings. Doing so makes the muscles too weak to contract and cause the headache.
Side effects of Botox include:
Cefaly. In March 2014, the FDA approved the first electronic device to prevent migraines. A statement from the FDA said that Cefaly is a small, portable, battery-powered, prescription device that resembles a plastic headband worn across the forehead and atop the ears. The device applies an electric current to the skin and underlying body tissues to stimulate branches of the trigeminal nerve, which has been associated with migraine headaches. The FDA said that the device should be used just once a day for 20 minutes.
Less than 5% of patients experience side effects during Cefaly treatment. These include:
In some cases, a surgical procedure that uses an endoscope (a slim tube) to work down under skin to the scalp may be effective. A group of scientists found earlier this year that surgery that went through the upper eyelid also seems to be effective. These procedures have yet to be FDA approved and remain controversial.
You can also try over-the-counter medicines such as acetaminophen, aspirin, and naproxen sodium (Aleve). But always ask your doctor if it is permissible for you to take these, since some of them may interact badly with other medicines you’re taking.
Complementary or alternative treatments may help migraine sufferers, but they should never be undertaken without consulting a doctor. The Mayo Clinic lists the following as possible alternative treatments:
Even if you’ve been under a physician’s care for migraines, there may be times when you need immediate medical attention. Don’t hesitate to seek help if your headache is more sudden or more severe than usual, or if you have symptoms other than the ones you usually have.
Some symptoms are of special concern:
In any case, better safe than sorry: ask for help right away if you think you need it.
Your primary care physician will likely be able to diagnose your condition based on your symptoms and family history. If he or she feels your case needs a more specialized kind of treatment, you may be referred to a headache specialist. Your doctor will likely know a specialist in your area or insurance network. Another possibility is a headache clinic, which comprises experts from several fields, including psychologists, physical therapists and neurologists. To find certified practitioners in these fields, visit the Migraine Research Foundation’s website.
Since many people suffer from migraine symptoms before they even consult a doctor, a diagnosis of migraine usually isn’t unexpected. Unless there is some underlying condition, a migraine diagnosis is not life-threatening. It is, however, a chronic condition without a cure.
To gain a better understanding of your condition and what living with your condition will mean, ask your doctor these questions:
