No peer-reviewed publication reporting this trial's results has been linked yet. This can indicate results are unpublished — a known publication-bias signal. We re-check periodically.
Summary
The investigators wish to investigate whether enhancement of SWS, which is seen after a drug called sodium oxybate, reduces the impact of sleep disruption in CFS on daytime function, specifically sleepiness and mental performance. This is a safe and well-tolerated drug that is licensed for excessive daytime sleepiness (EDS) and cataplexy associated with narcolepsy.
The investigators will study 12 patients diagnosed with CFS using international diagnostic guidelines. The investigators will record overnight sleep with EEG (brainwave) measurement on the 1st and 4th nights of a 4 night period during which sodium oxybate and placebo will be taken nightly, and the investigators will measure next-day sleepiness, mental performance and fatigue, and compare drug and placebo nights.
