What Causes Fibromyalgia?

 

While the underlying cause or causes of FM still remain a mystery, new research findings continue to bring us closer to understanding the basic mechanisms of fibromyalgia. Most researchers agree that FM is a disorder of central processing with neuroendocrine/neurotransmitter dysregulation. The FM patient experiences pain amplification due to abnormal sensory processing in the central nervous system. An increasing number of scientific studies now show multiple physiological abnormalities in the FM patient, including: increased levels of substance P in the spinal cord, low levels of blood flow to the thalamus region of the brain, HPA axis hypofunction, low levels of serotonin and tryptophan and abnormalities in cytokine function.

 

Recent studies show that genetic factors may predispose individuals to a genetic susceptibility to FM. For some, the onset of FM is slow; however, in a large percentage of patients the onset is triggered by an illness or injury that causes trauma to the body. These events may act to incite an undetected physiological problem already present.

 

Exciting new research has also begun in the areas of brain imaging and neurosurgery. Ongoing research will test the hypothesis that FM is caused by an interpretative defect in the central nervous system that brings about abnormal pain perception. Medical researchers have just begun to untangle the truths about this life-altering disease.
