migrainetrust.org: Migraine is a chronic health
condition. Most people who suffer from migraines get headaches that can be
severe. A migraine headache is usually an intense, throbbing pain on one, or
sometimes both, sides of the head. Most people with migraine headache feel the
pain in the temples or behind one eye or ear, although any part of the head can
be involved. Besides pain, migraine also can cause nausea and vomiting and
sensitivity to light and sound. Some people also may see spots or flashing
lights or have a temporary loss of vision.
What causes migraines?
The exact cause of migraine is not fully understood. Most researchers think that migraine is due to abnormal changes in levels of substances that are naturally produced in the brain. When the levels of these substances increase, they can cause inflammation. This inflammation then causes blood vessels in the brain to swell and press on nearby nerves, causing pain.
Genes also have been linked to migraine. People who get migraines may have abnormal genes that control the functions of certain brain cells.
Experts do know that people with migraines react to a variety of factors and events, called triggers. These triggers can vary from person to person 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. A person’s response to triggers also can vary from migraine to migraine.
Frequently mentioned migraine trigger factors include:
Keeping a migraine diary may help in identifying triggers. You can use our online diary to do this
When you should seek help for your symptoms?
The Migraine Trust recommends that migraine sufferers should obtain a diagnosis from their GP. A migraine diary can help a GP identify whether you have migraine and if so what type of migraine. The diary will also assist the GP in prescribing medication for your migraine.Thinks that should be covered in the diary are:
The Migraine Trust has an online diary which will help you record this information. Your doctor may also do an exam and ask more questions about your health history. This could include past head injury and sinus or dental problems. Your doctor may be able to diagnose migraine just from the information you provide. You may get a blood test or other tests, such as CT scan or MRI, if your doctor thinks that something else is causing your headaches.
Sometimes, headache can be a symptom of another health condition than migraine.
You should talk to your doctor about your headaches if:
Although migraine can change over the course of a person’s lifetime, it is always wise to see your GP if your migraine symptoms change, just to make sure the symptoms are still those of migraine.
Can stress cause migraine?
Yes. Stress can trigger both migraine and tension-type headache. Anything can actually trigger a migraine e.g. lack of sleep, missing a meal etc. if these are combined with stress then a migraine can be triggered.
Making time for yourself and finding ways to deal with stress are important.
Some things you can do to help prevent or reduce stress include:
There are no objective tests for migraine. It is diagnosed on the basis of the history, or the pattern of symptoms over time. This is why keeping a migraine diary can be helpful. Your doctor may refer you for tests such as CT or MRI scans to rule out other conditions that may cause similar symptoms.
How migraines are treated?
Migraine has no cure. But your migraines can be managed with your doctor’s help. Together, you will find ways to treat migraine symptoms when they happen, as well as ways to help make your migraines less frequent and severe. Your treatment plan may include some or all of these methods:
Medicine. There are two ways to approach the treatment of migraines with drugs: stopping a migraine in progress (called “abortive” or “acute” treatment) and prevention. Many people with migraine use both forms of treatment.
Acute treatment. Over-the-counter pain-relief drugs such as aspirin, acetaminophen, or NSAIDs (nonsteroidal anti-inflammatory drugs) like ibuprofen relieve mild migraine pain for some people, if taken early enough and at the right dose. If these drugs don’t work for you, your doctor might want you to try a prescription drug.
Most acute drugs for migraine work best when taken right away, when symptoms first begin. Always carry your migraine medicine with you in case of an attack. For people with extreme migraine pain, a powerful “rescue” drug might be prescribed, too. Because not everyone responds the same way to migraine medication, you will need to work with your doctor to find the treatment that works best for you.
Prevention. Some medicines used daily can help prevent attacks. Many of these drugs were designed to treat other health conditions, such as epilepsy and depression. These drugs may not prevent all migraines, but they can help a lot. Hormone therapy may help prevent attacks in women whose migraines seem to be linked to their menstrual cycle.
Ask your doctor about prevention drugs if:
Lifestyle changes. Practicing these habits can reduce the number of migraine attacks:
Alternative methods. Biofeedback has been shown to help some people with migraine. It involves learning how to monitor and control your body’s responses to stress, such as lowering heart rate and easing muscle tension. Other methods, such as acupuncture and relaxation, may help relieve stress. Counselling also can help if you think your migraines may be related to depression or anxiety. Talk with your doctor about these treatment methods.
