What is a Migraine Headache?
Migraine is a medical condition. Most people
who suffer from migraines get headaches that can be quite
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.
Migraine can occur any time of the day, though
it often starts in the morning. The pain can last a few
hours or up to one or two days. Some people get migraines
once or twice a week. Others, only once or twice a year.
Most of the time, migraines are not a threat to your overall
health. But migraine attacks can interfere with your day-to-day
life.
We don’t know what causes migraine,
but some things are more common in people who have them:
-
Most often, migraine affects people
between the ages of 15 and 55.
-
Most people have a family history of
migraine or of disabling headache.
-
They are more common in women.
-
Migraine often becomes less severe
and less frequent with age.
How common are migraines?
Migraine pain and symptoms affect 29.5 million
Americans. Migraine is the most common form of disabling
headache that sends patients to see their doctors.
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. Many women with migraine
tend to have attacks triggered by:
-
lack of or too much sleep
-
skipped meals
-
bright lights, loud noises, or strong
odors
-
hormone changes during the menstrual
cycle
-
stress and anxiety, or relaxation after
stress
-
weather changes
-
alcohol (often red wine)
-
caffeine (too much or withdrawal)
-
foods that contain nitrates, such as
hot dogs and lunch meats
-
foods that contain MSG (monosodium
glutamate), a flavor enhancer found in fast foods, broths,
seasonings, and spices
-
foods that contain tyramine, such as
aged cheeses, soy products, fava beans, hard sausages,
smoked fish, and Chianti wine
-
aspartame (NutraSweet® and Equal®)
To pinpoint your migraine triggers, keep
a headache diary. Each day you have a migraine headache,
put that in your diary. Also write down the:
-
the time of day your headache started
-
where you were and what you were doing
when the migraine started
-
what you ate or drank 24 hours before
the attack
-
each day you have your period, not
just the first day (This can allow you and your doctor
to see if your headaches occur at the same or similar
time as your period.)
-
Talk with your doctor about what sets
off your headaches to help find the right treatment
for you.
Are there different kinds of migraine?
There are many forms of migraine. The two
forms seen most often are migraine with aura and migraine
without aura.
Migraine with aura - previously called classical
migraine. With a migraine with aura, a person might have
these sensory symptoms - or the so-called “aura”
- 10 to 30 minutes before an attack:
-
seeing flashing lights, zigzag lines,
or blind spots
-
numbness; or tingling in the face or
hands
-
disturbed sense of smell, taste, or
touch
-
feeling mentally “fuzzy”
Only one in five people who get migraine
experience an aura. Women have this form of migraine less
often than men.
Migraine without aura - previously called
common migraine. With this form of migraine, a person does
not have an aura but has all the other features of an attack.
How can I tell if I have a migraine or
just a bad tension-type headache?
Compared with migraine, tension-type headache
is generally less severe and rarely disabling. Compare your
symptoms with those in this chart to see what type of headache
you might be having.

Note: Rebound headache may have features
of tension and/or migraine headache
Although fatigue and stress can bring on both
tension and migraine headaches, migraines can be triggered
by certain foods, changes in the body’s hormone levels,
and even changes in the weather.
There also are differences in how types of
headaches respond to treatment with medicines. Although
some over-the-counter drugs used to treat tension-type headaches
sometimes help migraine headaches, the drugs used to treat
migraine attacks do not work for tension-type headaches
for most people.
You can't tell the difference between a migraine
and a tension-type headache by how often they occur. Both
can occur at irregular intervals. Also, in rare cases, both
can occur daily or almost daily.
How can I tell if I have a migraine or
a sinus headache?
Many people confuse a sinus headache with
a migraine because pain and pressure in the sinuses, nasal
congestion, and watery eyes often occur with migraine. To
find out if your headache is sinus or migraine, ask yourself
these questions:
In addition to my sinus symptoms, do I have:
If you answer “yes” to two or
three of these questions, then most likely you have migraine
with sinus symptoms. A true sinus headache is rare and usually
occurs due to sinus infection. In a sinus infection, you
would also likely have a fever and thick nasal secretions
that are yellow, green, or blood-tinged. A sinus headache
should go away with treatment of the sinus infection.
When should I seek help for my headaches?
Sometimes, headache can signal a more serious
problem. You should talk to your doctor about your headaches
if:
-
you have several headaches per month
and each lasts for several hours or days
-
your headaches disrupt your home, work,
or school life
-
you have nausea, vomiting, vision,
or other sensory problems (such as numbness or tingling)
-
you have pain around the eye or ear
-
you have a severe headache with a stiff
neck
-
you have a headache with confusion
or loss of alertness
-
you have a headache with convulsions
-
you have a headache after a blow to
the head
-
you used to be headache-free, but now
have headaches a lot
What tests are used to find out if I have
migraine?
If you think you get migraine headaches,
talk with your doctor. Before your appointment, write down:
-
how often you have headaches
-
where the pain is
-
how long the headaches last
-
when the headaches happen, such as
during your period
-
other symptoms, such as nausea or blind
spots
-
any family history of migraine
-
all medicines you are taking for your
medical problems, even over-the-counter medicines (
bring medicines in their containers to the doctor)
-
all the medicines you have taken in
the past that you can recall and, if possible, the doses
you took and any side effects you had
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. Work with your doctor to
decide on the best tests for you.
Are migraine headaches more common in women
than men?
Yes. About three out of four people who have
migraines are women. Migraines are most common in women
between the ages of 20 and 45. At this time of life women
often have more job, family, and social duties. Women tend
to report more painful and longer lasting headaches and
more symptoms, such as nausea and vomiting. All these factors
make it hard for a woman to fulfill her roles at work and
at home when migraine strikes.
I get migraines right before my period.
Could they be related to my menstrual cycle?
More than half of migraines in women occur
right before, during, or after a woman has her period. This
often is called “menstrual migraine.” But, just
a small fraction of women who have migraine around their
period only have migraine at this time. Most have migraine
headaches at other times of the month as well.
How the menstrual cycle and migraine are linked
is still unclear. We know that just before the cycle begins,
levels of the female hormones, estrogen and progesterone,
go down sharply. This drop in hormones may trigger a migraine,
because estrogen controls chemicals in the brain that affect
a woman’s pain sensation.
Talk with your doctor if you think you have
menstrual migraine. You may find that medicines, making
lifestyle changes, and home treatment methods can prevent
or reduce the pain.
Can migraine be worse during menopause?
If your migraine headaches are closely linked
to your menstrual cycle, menopause may make them less severe.
As you get older, the nausea and vomiting may decrease as
well. About two-thirds of women with migraines report that
their symptoms improve with menopause.
But for some women, menopause worsens migraine
or triggers them to start. It is not clear why this happens.
Menopausal hormone therapy, which is prescribed for some
women during menopause, may be linked to migraines during
this time. In general, though, the worsening of migraine
symptoms goes away once menopause is complete.
Can using birth control pills make my migraines
worse?
In some women, birth control pills improve
migraine. The pills may help reduce the number of attacks
and their attacks may become less severe. But in other women,
the pills may worsen their migraines. In still other women,
taking birth control pills has no effect on their migraines.
The reason for these different responses is
not well understood. For women whose migraines get worse
when they take birth control pills, their attacks seem to
occur during the last week of the cycle. This is because
the last seven pills in most monthly pill packs don’t
have hormones; they are there to keep you in the habit of
taking your birth control daily. Without the hormones, your
body’s estrogen levels drop sharply. This may trigger
migraine in some women.
Talk with your doctor if you think birth control
pills are making your migraines worse. Switching to a pill
pack in which all the pills for the entire month contain
hormones and using that for three months in a row can improve
headaches. Lifestyle changes, such as getting on a regular
sleep pattern and eating healthy foods, can help too.
Can stress cause migraines?
Yes. Stress can trigger both migraine and
tension-type headache. Events like getting married, moving
to a new home, or having a baby can cause stress. But studies
show that everyday stresses—not major life changes—cause
most headaches. Juggling many roles, such as being a mother
and wife, having a career, and financial pressures, can
be daily stresses for women.
Making time for yourself and finding healthy
ways to deal with stress are important. Some things you
can do to help prevent or reduce stress include:
Try to figure out what causes you to feel
stressed. You may be able to cut out some of these stressors.
For example, if driving to work is stressful, try taking
the bus or subway. You can take this time to read or listen
to music, rather than deal with traffic. For stressors you
can't avoid, keeping organized and doing as much as you
can ahead of time will help you to feel in control.
How are migraines 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 these drugs don’t work for
you, your doctor might want you to try a prescription drug.
Two classes of drugs that doctors often try first are:
Triptans, which work by balancing the chemicals
in the brain. Examples include sumatriptan (Imitrex®),
rizatriptan (Maxalt®), zolmitriptan (Zomig®), almotriptan
(Axert®), eletriptan (Relpax®), naratriptan (Amerge®),
and frovatriptan (Frova®). Triptans can come as tablets
that you swallow, tablets that dissolve on your tongue,
nasal sprays, and as a shot. They should not be used if
you have heart disease or high blood pressure. Ergot derivatives
(ergotamine tartrate and dihydoergotamine), which work in
the same way as triptans. They should not be used if you
have heart disease or high blood pressure.
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 drugs, 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.
Some examples are:
-
antidepressants, such as amitriptyline
(Elavil®) or venlafaxine (Effexor®)
-
anti convulsants, such as divalproex
sodium (Depakote®) or topiramate (Topamax®)
-
beta-blockers, such as propranolol
(Inderal®) or timolol (Blocadren®)
-
calcium channel blockers, such as verapamil
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:
-
your migraines do not respond to drugs
for symptom relief
-
your migraines are disabling or cause
you to miss work, family activities, or social events
-
you are using pain-relief drugs more
than two times a week
Lifestyle changes. Practicing these habits
can reduce the number of migraine attacks:
-
Avoid or limit triggers.
-
Get up and go to bed the same time
every day.
-
Eat healthy foods and do not skip meals.
-
Engage in regular physical activity.
-
Limit alcohol and caffeine intake.
-
Learn ways to reduce and cope with
stress.
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. Counseling also can help if you think your
migraines may be related to depression or anxiety. Talk
with your doctor about these treatment methods.
What are rebound migraines?
Women who use acute pain-relief medicine
more than two or three times a week or more than 10 days
out of the month can set off a cycle called rebound. As
each dose of medicine wears off, the pain comes back, leading
the patient to take even more. This overuse causes your
medicine to stop helping your pain and actually start causing
headaches. Rebound headaches can occur with both over-the-counter
and prescription pain-relief medicines. They can also occur
whether you take them for headache or for another type of
pain. Talk to your doctor if you're caught in a rebound
cycle.
I'm pregnant. Can my migraines still be
treated?
Some migraine medicines should not be used
when you are pregnant because they can cause birth defects
and other problems. This includes over-the-counter medicines,
such as aspirin and ibuprofen. Talk with your doctor if
migraine is a problem while you are pregnant or if you are
planning to become pregnant. Your doctor might suggest a
medicine that will help you and that is safe during pregnancy.
Home treatment methods, such as doing relaxation exercises
and using cold packs, also might help ease your pain. The
good news is that for most women migraines improve or stop
from about the third month of the pregnancy.
I am breast feeding. Will taking medicine
for migraine hurt my baby?
Ask your doctor about what migraine medicines
are safe to take while breast feeding. Some medicines can
be passed through breast milk and might be harmful to your
baby.
What are some ways I can prevent migraine?
The best way to prevent migraine is to find
out what triggers your attacks and avoid or limit these
triggers. Since migraine headaches are more common during
times of stress, finding healthy ways to cut down on and
cope with stress might help. Talk with your doctor about
starting a fitness program or taking a class to learn relaxation
skills.
Talk with your doctor if you need to take
your pain-relief medicine more than twice a week. Doing
so can lead to rebound headaches. If your doctor has prescribed
medicine for you to help prevent migraine, take them exactly
as prescribed. Ask what you should do if you miss a dose
and how long you should take the medicine. Talk with your
doctor if the amount of medicine you are prescribed is not
helping your headaches.
What should I do when a migraine begins?
Work with your doctor to come up with a plan
for managing your migraines. Keeping a list of home treatment
methods that have worked for you in the past also can help.
When symptoms begin:
-
If you take migraine medicine, take
it right away.
-
Drink fluids, if you don't have nausea
during your migraine.
-
Lie down and rest in a dark, quiet
room, if that is practical.
Some people find the following useful:
-
a cold cloth on your head
-
rubbing or applying pressure to the
spot where you feel pain
-
massage or other relaxation exercises
