The association of sleep disturbances with fibromyalgia (FMS) symptomatology is now over 25 years old. A recent study (“Hypersomnolence in fibromyalgia syndrome” published in J Neurol Sci 196(1-2):77-80,2002) provides new information on the correlation of the intensity of daytime sleepiness and abnormalities; it underscores the importance of taking a detailed sleep history in all FMS patients. Although there are treatments for sleep apnea and periodic limb movement disorder, we still do not have good evidence that improved sleep benefits the physiological problems of increased pain sensitivity and neuroendocrine dysregulation.
