Migraine: What Is it?

One of the myths associated with Migraine is that it is

simply a very bad headache. Migraine is actually a

genetically-based disease. A headache is only a

symptom of that disease.

Migraine has many symptoms including visual

disturbances, sensitivity to sound and light, severe

headache, nausea, vomiting, hypersensitivity to feel

and touch, and vertigo. During an attack, Migraineurs,

people who suffer from Migraine, may also have

problems speaking and remembering the correct

words for what they're trying to say. One Migraine

episode can last hours, days, or weeks, leaving the

Migraineur virtually disabled for that period of time.


The exact cause of Migraine is still uncertain, but it is

known to be an inherited disease. People who have a

parent with Migraine have a 50% chance of also

suffering Migraine. The most prevalent theory of the

cause of Migraine is that chemical changes in the

blood vessels supplying the brain and its coverings

cause constriction (narrowing) and dilation (widening)

 of the blood vessels. Contrary to Migraine myth, the

cause of Migraine is not psychological.


A Migraine attack is induced by various triggers, some

controllable and some not. Controllable triggers

include bright light, various foods, and alcohol.

Uncontrollable triggers include weather patterns and

menstrual cycles. The triggers that cause Migraine

are many and vary from person to person.


Some Migraine episodes come on very quickly, with

little or no warning. In 30 to 40% of patients, a period

called the prodrome occurs hours or days before the

attack. During the prodrome, mood changes,

increased frequency of urination, food cravings, stiff

neck, and other symptoms may be experienced.

Sometimes, medications taken during this period can

help avert the attack. Unfortunately, patients

sometimes either don't notice or misunderstand the

symptoms of the prodrome. The prodrome may be

followed by an aura, symptoms that can last for up to

an hour just prior to the headache stage of an attack.

Symptoms that can occur during the aura include

visual disturbances; hypersensitivity to light sound,

odors, touch and feel; vertigo; and speech

disruptions.  Again, if the aura occurs and is noticed,

sometimes medications taken at this time can head

off or lessen the severity of the ensuing headache.

The headache itself varies in characteristics, and

usually lasts from 4 to 72 hours. The period after the

headache is called the postdrome, and can last up to

24 hours after the headache ends. Symptoms that

persist through the postdrome include, moodiness,

lack of concentration, and weakness.


In addition to medications to treat the symptoms of

Migraine, there are several classes of drugs being

used to help prevent Migraine episodes. In addition,

alternative and complementary methods such as

acupuncture, massage therapy, and relaxation

techniques are being employed both as preventatives

and as treatments during episodes.


Migraine is a genetically-based, disabling, under-

diagnosed, under-treated, and often misunderstood

disease. As research into cause, treatment, and

prevention continue, Migraineurs have more choices

and hope now than they did before.
