Description:

As an extension of a study on the relationship between sleep deprivation and cerebrospinal fluid (CSF) biomarkers for Alzheimer’s disease, we performed two Lumbar punctures (LPs) within three days in 13 healthy volunteers. Our aim was to investigate CSF biomarker dynamics in relation to sleep deprivation. An unexpected sharp rise in biomarker concentrations in the second sample made us consider an artifact and we therefore repeated the experiment, but without sleep restriction, in four additional individuals. A similar rise in biomarker levels were evident, suggesting an inherent methodological problem with repeated LPs.

13 healthy volunteers recruited by posters on university campus. 20-40 years of age with no sleep disturbances. Body-Mass-index (BMI) < 30 kg/m2. No continual use of medication or relevant chronic diseases. Self-reported normal bedtime < 00.00, regular morning awakening hours 06.00-09.00, habitual sleep duration of between 6.5-8.5 hours and absence of sleep disturbances (such as chronic insomnia/daytime sleepiness/narcolepsy).
