Migraine—Adult

Definition

Migraine is a headache disorder. Headaches may happen many times a week or once every few years. Sensations called auras may come before a migraine headache.

Migraines can be so severe that they get in the way of daily activities.

Causes

The exact cause is not known. Genes may play a role.

Some things that may trigger a migraine are:

  • Things in the environment, such as odors and bright lights
  • Certain foods and drinks, such as alcohol
  • Some medicines
  • Changes in sleep patterns
  • Stress
  • Changes in the body, such as menstruation and puberty
  • Weather changes

Risk Factors

Migraines are more common in people under 50 years of age. They are also more common in women.

Other things that may raise the risk are:

  • A family history of migraines
  • Hormonal changes from menstruation

Symptoms

Migraines happen in these phases:

Warning

A warning may come before a migraine. A person may have these symptoms in the hours or days before a headache:

  • Changes in mood, behavior, and activity level
  • Tiredness and yawning
  • Food cravings or lack of hunger
  • Nausea
  • Diarrhea
  • Sensitivity to light

Aura

Auras often last about 15 to 30 minutes. Visual auras are the most common type. A person may have:

  • Flashing lights, spots, or zig zag lines
  • Partial loss of vision that lasts a short time
  • Weakness in an arm or leg
  • Numbness or tingling in the face and hands
  • Confusion
  • Lightheadedness
  • Problems speaking

Headache

Migraine pain may start within an hour of an aura ending. Problems may be:

  • A headache on one or both sides that may feel:
    • Moderate or severe
    • Throbbing or pulsating
    • More severe with bright light, loud sound, or movement
  • Nausea or vomiting
  • Diarrhea
  • Lightheadedness

Post-Headache Period

Migraines usually last 4 to 72 hours. They often go away with sleep. After the headache, a person may have:

  • Problems with focus
  • Tiredness
  • Sore muscles
  • Irritability
  • Mood changes

Diagnosis

The doctor will ask about your symptoms and health history. A physical exam will be done. A neurological exam may be done.

Images may be taken of your head. This can be done with:

Treatment

The goal of treatment is to ease headaches to improve function and quality of life. Using cold compresses and trying to sleep in a dark, quiet room may help.

Other options are:

Medications

The doctor may advise these medicines to ease migraine pain:

  • Over-the-counter pain medicine, such as acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Triptans
  • Dopamine antagonists
  • Ergotamine tartrate
  • Steroids
  • Calcitonin gene-related peptide (CGRP) inhibitors

Regular use of some over-the-counter medicines may cause a rebound headache.

The doctor may advise these medicines to prevent migraines in people who get them a lot:

  • Beta-blockers
  • Calcium channel blockers
  • Anti-seizure medicine
  • Tricyclic antidepressants
  • Angiotensin-converting enzyme (ACE) inhibitors or angiotensin-II receptor blockers (ARBs)
  • Calcitonin gene-related peptide (CGRP) inhibitors

Therapy

Therapy may be used to reduce the length and frequency of headaches. Methods may be cognitive behavioral therapy, biofeedback, or relaxation methods.

Procedures

Procedures that may be done are:

  • Botulinum toxin injections may be used to prevent migraines. They may also reduce headache pain and duration.
  • Transcranial magnetic stimulation may also be used by people with migraine with aura who have not been helped by other treatments.

Some people may have surgery when other methods do not help. Some migraines are triggered when a nerve in the head is stimulated. Surgery can be done to find the nerve and turn it off. This may make the headaches go away or make them happen less often.

Prevention

Migraines may be prevented by:

  • Using relaxation methods
  • Eating a healthful diet and drinking plenty of water
  • Exercising regularly
  • Avoiding known migraine triggers
  • Getting enough sleep
  • Taking prescription medicine to prevent migraines
