What is Migraine?
The
pain of a migraine headache is often described as an intense pulsing or
throbbing pain in one area of the head. It is often accompanied by
extreme sensitivity to light and sound, nausea, and vomiting. Migraine
is three times more common in women than in men. Some individuals can
predict the onset of a migraine because it is preceded by an "aura,"
visual disturbances that appear as flashing lights, zig-zag lines or a
temporary loss of vision. People with migraine tend to have recurring
attacks triggered by a lack of food or sleep, exposure to light, or
hormonal irregularities (only in women). Anxiety, stress, or relaxation
after stress can also be triggers. For many years, scientists believed
that migraines were linked to the dilation and constriction of blood
vessels in the head. Investigators now believe that migraine is caused
by inherited abnormalities in genes that control the activities of
certain cell populations in the brain.
Is there any treatment?
There
are two ways to approach the treatment of migraine headache with drugs:
prevent the attacks, or relieve the symptoms during the attacks. Many
people with migraine use both approaches by taking medications
originally developed for epilepsy and depression to prevent future
attacks, and treating attacks when they happen with drugs called
triptans that relieve pain and restore function. Hormone therapy may
help some women whose migraines seem to be linked to their menstrual
cycle. Stress management strategies, such as exercise, relaxation,
biofeedback, and other therapies designed to help limit discomfort, may
also reduce the occurrence and severity of migraine attacks.
What is the prognosis?
Taking
a combination of drugs to prevent and treat migraine attacks when they
happen helps most people with migraine to limit the disabling effects
of these headaches. Women whose migraine attacks occur in association
with their menstrual cycle are likely to have fewer attacks and milder
symptoms after menopause.
What research is being done?
Researchers
believe that migraine is the result of fundamental neurological
abnormalities caused by genetic mutations at work in the brain.
Investigations of the more rare, familial subtypes of migraine are
yielding information about specific genes and what they do, or don't
do, to cause the pain of migraine headache. Understanding the cascade
of biological events that happen in the brain to cause a migraine, and
the mechanisms that underlie these events, will give researchers
opportunities to develop and test drugs that could prevent or interrupt
a migraine attack.
