Sleep disturbances: core symptoms of major depressive disorder rather than associated or comorbid disorders

Mendlewicz, Julien·2009·The World Journal of Biological Psychiatry

Abstract

Depression is increasingly prevalent in Western countries. It has severe consequences and is associated with increased rates of disability, morbidity, and mortality. Despite numerous therapeutic options, a great number of depressed patients do not achieve full remission. In addition, despite good short-term outcomes, long-term therapeutic results remain disappointing and associated with a poor prognosis, raising significant concern in terms of public health. Impaired sleep - especially insomnia - may be at least partly responsible for this problem. Very close relationships between major depressive disorder (MDD) and sleep disorders have been observed. In particular, residual symptoms of sleep disturbance in a remitted patient may predict a relapse of the disease. However, most currently available antidepressants do not always take into consideration the sleep disturbances of depressed patients; some agents long used in clinical practice even appear to worsen them by their sleep-inhibiting properties. But some other new medications were shown to relieve early sleep disturbance in addition to alleviating other depression-related symptoms. This positive impact should promote compliance with medication and psychological treatments, and increase daytime performance and overall functioning. Complete remission of MDD appears therefore to depend on the relief of sleep disturbances, a core symptom of MDD that should be taken into consideration and treated early in depressed patients.

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.
