Abstract

Background: The hypothalamic neuropeptide hypocretin (orexin) modulates sleep-wake, feeding and endocrine functions. Cerebrospinal fluid (CSF) hypocretin-1 (Hcrt-1) concentrations are low in patients with narcolepsy-cataplexy, a sleep disorder characterized by hypersomnolence and rapid eye movement (REM) sleep abnormalities. Methods: We determined CSF Hcrt-1 concentrations of patients with the fibromyalgia syndrome (FMS), a condition characterized by fatigue, insomnia and in some cases daytime hypersomnolence. Results: Basal CSF levels of Hcrt-1 in FMS did not differ from those in healthy normal controls. Conclusions: These findings suggest that abnormally low Hcrt-1 is not a likely cause of fatigue in FMS.
