ABSTRACT: Autonomic nervous system dysfunction observed in fibromyalgia, characterized without exception by a sympathetic hyperactivity and hyporeactivity, has been reported. However, several studies demonstrated reduced levels of norepinephrine and neuropeptide Y at rest and after tilt table in some patients, which was improved by beta-stimulating agents. These findings support heterogeneity in fibromyalgia-associated dysautonomia. Fibromyalgia could be a generalized sympathetic dystrophy since both conditions are activated by trauma and partly linked to sympathetic mechanisms. Yet they differ on several points: hormonal and neurochemical abnormalities are observed in fibromyalgia whereas activation by peripheral trauma and hyperosteolysis are observed in reflex sympathetic dystrophy.

About FMS Global News

Folllowing Rick Usher's death in December 2008, at his request in September of that year, I had agreed, as his principal contributor and an experienced journalist, to run the FMS Global News service due to his heavy commitments to music and raising research funds through this avenue. Following his sad and sudden death I hope to continue his work as he would have wished.
