TLDR
In this paper, the effect of the presence of tardive dyskinesia or active psychotic symptoms that further skew the sleep polygraphic measurements in these patients is discussed. But the results of these studies are weakened by sampling bias.About:

Journal ArticleDOI
Sleep and depression--results from psychobiological studies: an overview.
TL;DR: Data indicate a strong bi-directional relationship between sleep, sleep alterations and depression, and most of the effective antidepressant agents suppress REM sleep.
Journal ArticleDOI
Human sleep, sleep loss and behaviour. Implications for the prefrontal cortex and psychiatric disorder.
TL;DR: The prefrontal cortex (PFC) consists of the cortex lying in front of the primary and secondary motor cortex, and includes the dorsolateral and orbital areas, frontal eye fields, and Broca's area.
Journal ArticleDOI
Sleep disturbances in patients with schizophrenia : impact and effect of antipsychotics.
TL;DR: It appears possible that the high-potency drugs exert their effects on sleep in schizophrenic patients, for the most part, in an indirect way by suppressing stressful psychotic symptomatology.
Journal Article
Influence of sleep-wake and circadian rhythm disturbances in psychiatric disorders.
TL;DR: The results have implications for analyzing diurnal variation of mood in unipolar and bipolar affective disorders and sleep disturbances in other major psychiatric conditions such as chronic schizophrenia.

Sleep in schizophrenia patients and the effects of antipsychotic drugs
Jaime M. Monti,Daniel Monti +1 more
TL;DR: The sleep disturbances of either never-medicated or previously treated schizophrenia patients are characterized by a sleep-onset and maintenance insomnia, and the atypical antipsychotics olanzapine, risperidone, and clozapine significantly increase total sleep time and stage 2 sleep.

Journal Article
REM latency: a psychobiologic marker for primary depressive disease.
TL;DR: It is indicated that short REM latency is found in virtually all primary depressive illness and is absent in secondary depression, and it is argued that the phenomenon is independent of age, drug effect and changes in other sleep parameters.

Interval between onset of sleep and rapid-eye-movement sleep as an indicator of depression
David J. Kupfer,F. Gordon Foster +1 more
TL;DR: An analysis of electroencephalographic patterns in thirty-five consecutive patients admitted for the treatment of depression revealed that a single sleep characteristic—the interval between onset of sleep and the start of rapid-eye-movement (R.E.M.M.) sleep—is an objective indicator of depressive disease and correlates inversely with its severity.

Electroencephalographic Sleep in Young, Never-Medicated Schizophrenics: A Comparison With Delusional and Nondelusional Depressives and With Healthy Controls
TL;DR: It is suggested that young, never-medicated schizophrenics do not show the characteristic constellation of abnormalities in the first NREM-REM cycle seen in patients with major depression, however, decreased slow-wave sleep should be investigated as a possible marker for negative symptoms in schizophrenia.
Journal ArticleDOI
Abnormal rapid eye movement latencies in schizophrenia.
TL;DR: Sleep patterns of schizophrenic patients with those of normal controls and patients with major depressive disorder and schizoaffective disorder are compared using Research Diagnostic Criteria.

Further Evidence of Abnormal Non-Rapid-Eye-Movement Sleep in Schizophrenia
TL;DR: In five unmedicated, recently rehospitalized schizophrenic patients the authors found reduced delta amplitude and abundance (and increased spindle density) in NREMP1 (also called "REM latency") as compared with ambulatory normal controls, which may underlie the abnormal rapid eye movement distributions sometimes found in schizophrenic and depressed patients.
