Sleep deprivation, alone or in combination with pharmacological treatment and as part of a chronotherapy package, is of potential use for people with major depressive episodes, however the evidence base is still conflicting. The aim of this systematic review and meta-analysis is to assess the clinical effects of sleep deprivation in comparison to any other intervention for the acute and long-term treatment of mood disorders. We searched electronic databases and trial registries (last update: 16th October 2021) for published and unpublished randomised controlled trials recruiting participants with a major depressive episode in unipolar or bipolar affective disorder. The clinical outcomes of interest were the reduction in depressive symptoms at different timepoints and the number of participants experiencing at least one side effect. Overall, 29 trials (1246 participants) were included. We did not find any difference in change in symptoms or all-cause discontinuation between interventions including SD compared to a control of the same intervention except without SD. In the included studies there were no available data for adverse events. Using the most methodologically rigorous approach, we did not find evidence that the addition of sleep deprivation to treatment packages leads to enhanced depressive outcomes.
