Abstract

Background The most characteristic alterations in the sleep electroencephalogram (EEG) during major depression are a shortened latency to rapid eye movement (REM) sleep and an elevated REM density. Because these changes persist in remission, they might represent vulnerability markers. To identify vulnerability markers, we investigated premorbid sleep EEG parameters in healthy high-risk probands (HRPs) with a positive family history of affective disorders.Methods We identified 136 depressed inpatients from referrals to our hospital who had first-degree relatives with an affective disorder as well as first-degree relatives with no current or lifetime history of psychiatric disorders. The latter (the HRP group) were investigated by polysomnography. During the follow-up period, 20 HRPs developed an affective disorder. Their premorbid sleep data were analyzed.Results Premorbid sleep EEG of affected HRPs showed an increased REM density (total night and first REM period) compared with the control group without personal or family history of a psychiatric disorder.Conclusions Increased REM density can be observed not only in patients with depression, but also in their healthy relatives. Moreover, it is predictive for the onset of a psychiatric disorder. Therefore, it can be recommended as a possible endophenotype of these diseases.

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.
