Fibromyalgia: evolving concepts and management in primary care settings

Abstract

During the last 10 years, fibromyalgia (FM) research shifted focus from psychological and behavioral issues to sleep, nociception, and neuroendocrinology. Although there are still no definitive markers of the disease, a barrage of studies in physiological, psychological, and behavioral sciences have now dispelled the belief that FM is solely psychosomatic. Studies in the late 1990s as well as in the early part of the current decade reaffirm earlier research that sleep abnormalities and alterations in nociception may partly be responsible for FM. While sleep research shows that FM patients typically are deficient in stage IV (restorative) sleep, most current studies in nociception now affirm that patients with FM exhibit low serum serotonin in combination with increased substance P levels in the cerebrospinal fluid. Although there is still no cure, treatment aimed at promoting sleep, interrupting nociception, and actively involving patient and family in FM management can bring lifetime control for the disease.
