Abstract

Depressive insomnia and diurnal fluctuations of mood and activity are core clinical features of mood disorders. Here we studied the effect of CLOCK 3111 T/C SNP (rs1801260) on the actimetric recorded diurnal activity and nocturnal sleep of 39 bipolar depressed inpatients. Compared to T/T homozygotes, carriers of the C allele had a similar degree of severity of depression, but showed higher activity levels in the evening, a delayed sleep onset (mean 79 min later), and a reduced amount of sleep during the night (mean 75 min less). Ongoing lithium treatment significantly interacted with rs1801260 by enhancing activity levels in the evening and reducing the differences among genotype groups. Individual characteristics of the molecular clock can influence sleep symptoms in mood disorders. © 2007 Wiley‐Liss, Inc.

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.
