The Mechanism of Migraine
What is occurring physiologically when a migraine headache happens? It seems the start of a migraine headache is in the brain stem. The brain stem is a small bit above the spinal cord, but underneath the cortex of the brain. The migraine “control center” in the brain stem emits signals to the blood vessels lining the brain, requesting these blood vessels to dilate and expand. In the process, pain signals are sent back to the “control center”.
Migraine Versus other Headaches
What is the difference between a migraine and a regular headache? Migraine headaches are primarily one-sided, with concomitant nausea, loss of appetite and vomiting. Often, light sensitivity accompanies the migraine headache. Contrast this with the common tension headache, which is distributed over the whole head. Also, the routine headache isn't as extensive as a migraine headache. Migraine is better described as a throbbing headache, whereas a tension headache merely has a dull, constant ache.
Different Types of Migraines
There are common migraines and classic migraines. Classic migraines start with a “aura” that involves changes in visual perception. The auras go on about 10-30 minutes and are associated with flashing lights and/or colors, and maybe a temporary loss of vision. You might feel a burning or strange prickly feeling, and possibly feel irritable and restless.
A common migraine does not involve an aura. A common migraine starts more slowly than a classic migraine and the pain may only be unilateral. However, a common migraine lasts longer than a classic one, and may interfere more extensively with your normal activities.
Alternative Treatmnents
A few unconventional treatments have proven effective. These include chiropractic manipulation, acupuncture and biofeedback therapy. Magnetic therapy in addition has been used with success. Magnetic therapy leads to increased electrical activity in the brain. This steps up neural conductivity which then stimulates within the brain the secretion of the hormones serotonin and melatonin. Serotonin controls moods and depression tendencies. Magnetic therapy treatment generally involves either:
- A magnetic pillow pad
- A magnetic head band
- A magnetic eye mask
A natural treatment method includes using an ice pack on the back of the neck around the base of the skull. This lessens the flow of blood to the head, resulting in less pressure in the head. Make sure there is a barrier between the ice pack and the skin, for example a wet cloth.
Some herbal remedies have been utilized. These include feverfew, chamomile, valerian, white willow and skullcap. These following supplements also should help individuals suffering from migraines:
- Coenzyme Q10
- Magnesium
- Multivitamins/multi-minerals
- Vitamin B12
- Vitamin B2
Finally, some other remedies include extra magnesium in one's diet, regular physical exercise, and relaxation techniques like yoga or transcendental meditation. Recently, a new form of migraine treatment called Transcutaneous Electrical Nerve Stimulation (TENS) has been developed. TENS sends a mild shock of electricity, avoiding the body from receiving migraine pain signals.
Migraine Triggers
Some environmental triggers seem to initiate a migraine attack. These triggers include some foods, stressful lifestyles, and exposure to bright lights or loud sounds. Commonly, some foods such as red wine, cheese, chocolate, meats cured with nitrates, and MSG can induce migraine headaches. Other triggers include anger and/or stress, too little sleep, menstruation, and weather changes. Withdrawal from caffeine and ergotamines can also cause migraine headaches. The rationale why foods like cheese, chocolates and alcohols can trigger migraines is the occurrence of amines that act on the vascular system by producing venal constriction through release of catecholamines.
Migraine Treatments
There is a broad range of treatments for migraines. They vary from medications such as the triptans (sumatriptan, zolmitriptan, naratriptan, rizatriptan, almotriptan, frovatriptan) to consuming healthful foodstuffs, to precluding certain stressful lifestyles to relaxation techniques. Migraine headache intensity varies from one individual to the next, and no clear cut remedy now exists.
Specific prescription medications might ease the symptoms of migraines. These include Imitrex, Maxalt, Zomig, Relpax, Midrin, and Migranal. They exert their action by causing cerebral vasoconstriction.
Migraine Symptoms
The ensuing is an incomplete directory of migraine symptoms:
- Auras (light spots)
- Nausea
- Vomiting
- Sensitivity to light and sound
- Serious pain in the head
- Numbness
- Difficulty in speaking
- Throbbing or pulsing headache (generally unilateral)
Migraine attacks frequently recur, and the symptoms will differ from person to person.
Migraine Complications
A good amount of symptoms of migraines disappear after a few days. Should migraines are left untreated, yet, they might induce strokes, aneurysms, permanent vision loss, and even comas.
