During the Stone Age, pieces of a headache
sufferer's skull were cut away with flint
instruments to relieve pain. Another unpleasant
remedy used in the British Isles around the ninth
Century involved drinking "the juice of elderseed,
cow's brain, and goat's dung dissolved in vinegar."
Fortunately, today's headache patients are spared
such drastic measures.
Drug therapy, biofeedback training, stress
reduction, and elimination of certain foods from the
diet are the most common methods of preventing and
controlling migraine and other vascular headaches.
Joan, the migraine sufferer, was helped by treatment
with a combination of an antimigraine drug and diet
control.
Regular exercise, such as swimming or vigorous
walking, can also reduce the frequency and severity
of migraine headaches. Joan found that whirlpool and
yoga baths helped her relax.
During a migraine headache, temporary relief can
sometimes be obtained by applying cold packs to the
head or by pressing on the bulging artery found in
front of the ear on the painful side of the head.
Drug therapy. There are two ways to
approach the treatment of migraine headache with
drugs: prevent the attacks, or relieve symptoms
after the headache occurs.
For infrequent migraine, drugs can be taken at
the first sign of a headache in order to stop it or
to at least ease the pain. People who get occasional
mild migraine may benefit by taking aspirin or
acetaminophen at the start of an attack. Aspirin
raises a person's tolerance to pain and also
discourages clumping of blood platelets. Small
amounts of caffeine may be useful if taken in the
early stages of migraine. But for most migraine
sufferers who get moderate to severe headaches, and
for all cluster headache patients (see section
"Besides Migraine, What Are Other Types of Vascular
Headaches?"), stronger drugs may be necessary to
control the pain.
Several drugs for the prevention of migraine have
been developed in recent years, including serotonin
agonists which mimic the action of this key brain
chemical. One of the most commonly used drugs for
the relief of classic and common migraine symptoms
is sumatriptan, which binds to serotonin receptors.
For optimal benefit, the drug is taken during the
early stages of an attack. If a migraine has been in
progress for about an hour after the drug is taken,
a repeat dose can be given.
Physicians caution that sumatriptan should not be
taken by people who have angina pectoris, basilar
migraine, severe hypertension, or vascular, or liver
disease.
Another migraine drug is ergotamine tartrate, a
vasoconstrictor which helps counteract the painful
dilation stage of the headache. Other drugs that
constrict dilated blood vessels or help reduce blood
vessel inflammation also are available.
For headaches that occur three or more times a
month, preventive treatment is usually recommended.
Drugs used to prevent classic and common migraine
include methysergide maleate, which counteracts
blood vessel constriction; propranolol hydrochloride,
which stops blood vessel dilation; amitriptyline, an
antidepressant; valproic acid, an anticonvulsant;
and verapamil, a calcium channel blocker.
Antidepressants called MAO inhibitors also
prevent migraine. These drugs block an enzyme called
monoamine oxidase which normally helps nerve cells
absorb the artery-constricting brain chemical,
serotonin. MAO inhibitors can have potentially
serious side effects - particularly if taken while
ingesting foods or beverages that contain tyramine,
a substance that constricts arteries.
Many antimigraine drugs can have adverse side
effects. But like most medicines they are relatively
safe when used carefully and under a physician's
supervision. To avoid long-term side effects of
preventive medications, headache specialists advise
patients to reduce the dosage of these drugs and
then stop taking them as soon as possible.
Biofeedback and relaxation training.
Drug therapy for migraine is often combined with
biofeedback and relaxation training. Biofeedback
refers to a technique that can give people better
control over such body function indicators as blood
pressure, heart rate, temperature, muscle tension,
and brain waves. Thermal biofeedback allows a
patient to consciously raise hand temperature. Some
patients who are able to increase hand temperature
can reduce the number and intensity of migraines.
The mechanisms underlying these self-regulation
treatments are being studied by research scientists.
"To succeed in biofeedback," says a headache
specialist, "you must be able to concentrate and you
must be motivated to get well."
A patient learning thermal biofeedback wears a
device which transmits the temperature of an index
finger or hand to a monitor. While the patient tries
to warm his hands, the monitor provides feedback
either on a gauge that shows the temperature reading
or by emitting a sound or beep that increases in
intensity as the temperature increases. The patient
is not told how to raise hand temperature, but is
given suggestions such as "Imagine your hands feel
very warm and heavy."
"I have a good imagination," says one headache
sufferer who traded in her medication for thermal
biofeedback. The technique decreased the number and
severity of headaches she experienced.
In another type of biofeedback called
electromyographic or EMG training, the
patient learns to control muscle tension in the face,
neck, and shoulders.
Either kind of biofeedback may be combined with
relaxation training, during which patients learn to
relax the mind and body.
Biofeedback can be practiced at home with a
portable monitor. But the ultimate goal of treatment
is to wean the patient from the machine. The patient
can then use biofeedback anywhere at the first sign
of a headache.
