Abstract

Sleep loss impairs waking functions and is homeostatically compensated in recovery sleep. The mechanisms underlying the consequences of prolonged wakefulness are unknown. The stimulant modafinil may promote primarily dopaminergic neurotransmission. Catechol-O-methyltransferase (COMT) catalyzes the breakdown of cerebral dopamine. A functional Val158Met polymorphism reduces COMT activity, and Val/Val homozygous individuals presumably have lower dopaminergic signaling in the prefrontal cortex than do Met/Met homozygotes. We quantified the contribution of this polymorphism to the effects of sleep deprivation and modafinil on subjective state, cognitive performance, and recovery sleep in healthy volunteers. Two-time 100 mg modafinil potently improved vigor and well-being, and maintained baseline performance with respect to executive functioning and vigilant attention throughout sleep deprivation in Val/Val genotype subjects but was hardly effective in subjects with the Met/Met genotype. Neither modafinil nor the Val158Met polymorphism affected distinct markers of sleep homeostasis in recovery sleep. In conclusion, dopaminergic mechanisms contribute to impaired waking functions after sleep loss.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
