Migraine Headache

This is the second most common headache and occurs with an average frequency of about 12% in the general population. Women outnumber men in the U.S. by a factor of 3 to 1 with migraines. There is a genetic factor as migraine sufferers' family members are getting migraines about 3-fold more often than the general public.

Symptoms

Migraines present in 85% without an aura (formerly called "common migraines") and in 15% with an aura (formerly called "classic migraines"). An aura consists of changed behaviors such as pacing, yawning, craving for certain foods, lethargy, depression or mild euphoria. These symptoms are separate from the migraine aura, which consists of neurological symptoms such as visual symptoms that come on 1 or 2 hours before the migraine headache starts and disappear about 1 hour after the start of the migraine.

The actual migraine headache is on one side of the head, can last 4 hours to 3 days, is throbbing in nature, moderately to severe in intensity and is made worse by physical activity, light or noise. The patient is complaining of nausea and might be vomiting with a severe migraine. In a small percentage of patients a more severe form of complicated migraine (or "migraine with prolonged aura") can develop where the patient has prolonged symptoms of a migraine aura for more than 1 hour, but usually less than 1 week. These patients should be investigated thoroughly by a neurologist as a small percentage of these patients can develop persistent neurological symptoms including a "migrainous infarction" (=a stroke like clinical picture) (Ref. 1, p. 2067).

Treatment

Medication that is used is quite different between attacks as compared to during an attack. During a migraine attack non steroidal anti-inflammatory drugs (=NSAIDs) and dihydroergotamine or sumatriptan, which stimulate serotonin receptors, are used. Drug dependency issues on narcotics has to be discussed frankly with the patient because of the danger of rebound migraines that are triggered by the contiued use of narcotics. Sumatriptan can be given intranasally, but overuse and dependency on this medication also must be monitored by the physician and in males there is a higher risk for heart attacks as a side-effect of the medication. Prochlorperazine (brandname: Stemetil) can be given intravenously in the Emergency Room as a drip and can abort a migraine.

Between migraine attacks there is a number of preventatives that are effective. They consist of beta-blockers such as propranolol, metoprolol, timolol and others; NSAIDs such as ASA, naproxen or ketoprofen; calcium channel blockers such as verapamil or flunarizine; antidepressants such as amitriptyline.

Gabapentin is the latest medication that has been found useful in several smaller studies. Gabapentin(brand name: Neurontin) releases GABA in some parts of the brain and inhibits the NMDA pain receptors. Dr. Stephen Clarke, Clinical Assistant Professor in the Div. of Neurology of the University of BC/Vancouver/Canada, reviewed the use of gabapentin at a conference in Vancouver/BC in November 2004 (Ref. 10).

Other medication for headache prevention are the anticonvulsant gabapentin; the MAO inhibitor phenelzine and the serotonin stimulating drugs methysergide and cyproheptatine. Unfortunately many of these medications do not work 100% and there is a lack of good randomized studies to prove effectiveness. It is important to include in the regimen of anti-migraine measures non drug regimens such as avoidance of triggering factors like certain foods (chocolate, red wine, certain cheeses and strong smells) or bright lights and noises. Consistent sleeping patterns and meal times need to be established. Counseling when emotional factors play a role, relaxation techniques like yoga, self hypnosis and biofeedback methods are all helpful as well. The more complex cases should be referred to a neurologist or even a multidisciplinary headache clinic.

There is an FDA approved non-drug method available, IceWave patches from Lifewave, which will control pain including headaches. This is mentioned in the book "Breakthrough" by Suzanne Somers (Ref. 11) where newer insights of antiaging medicine are also reviewed. Although the patches are placed over acupuncture points, there are no needles involved. Nanotechnology, a newer technology, was used in the manufacturing of these patches and infrared (heat) waves from body heat are utilized to stimulate an acupuncture point, which modifies pain perception and reduces pain to half or less. Medically this would be considered an excellent pain reliever. For more info on the patches see the IceWave patches from Lifewave link above (click "products").
