Migraine headaches can be classified into two types: classical and common. The classical migraine is a headache that follows an aura or some type of spontaneous event such as numbness or tingling. The aura may be flashes of light, squiggly lines, or a halo effect. The common migraine does not have an aura associated with it. Most people who suffer from migraines suffer from common migraines, usually at a 3:1 ratio.
Some 28 million Americans suffer from migraines, and millions go without treatment. Scientists once thought migraines were caused by abnormally dilated or enlarged blood vessels. New imaging devices have allowed them to watch brains during migraine attacks, and scientists are discovering that sufferers have abnormally excitable neurons, or brain nerve cells.
The latest research in regard to migraines is a mechanism called cortical spreading depression, or CSD. Prior to the onset of pain in a migraine, researchers have observed a sudden burst of cortical activity that occurs most commonly in the occipital lobes (back part of the brain). The occipital lobe will increase in frequency of firing, or have a burst of activity, and then there will be an episode of silence of depressed activity. The actual activity of the brain becomes depressed when compared to normal. The resulting pain comes from either the brain stem activation, the blood vessels inflamed by rapidly exchanging blood flow, or both.
As a Board Certified Chiropractic Neurologist, I take a different approach to the treatment and prevention of migraines. After a thorough neurological exam, I determine which part of the nervous system is not functioning properly. In many migraine patients, I find a high mesencephalic output.
There are three parts to the brain stem: top, middle and lower. The mesencephalon is the top part of the brain stem. A high output of the mesencephalon will cause an increased pulse and heart rate, the inability to sleep, or a waking, fitful sleep. Other symptoms might include urinary tract infections, increased warmth and sweating, and sensitivity to light. Along with a high mesencephalic output, the migraine patient may present with a decreased output of the cerebellum. The cerebellum controls balance, coordinated movement, and the involuntary muscles of the spinal column.
No matter what the condition, it is imperative that the chiropractic neurologist performs a thorough and comprehensive exam to determine the exact nature of the patient’s condition.
