SLEEP PROFILE IN PATIENTS WITH SCHIZOPHRENIA: A POLYSOMNOGRAPHIC EVALUATION IN AN EGYPTIAN SAMPLE
Marwa Mohamed Ghanem;
Abstract
Abstract
Background: The normal dream experience is similar to psychosis. Hallucinations, perceptual
distortions, bizarre thinking, and temporary delusions can intermingle with more normal thought and
perceptual processes. The discovery of rapid eye movement (REM) sleep and its associated dream reports
not only ushered in the modern era of sleep research but also stimulated many of the studies of the sleep
of schizophrenics. Studies explored the hypothesis that the pathogenesis of schizophrenia might rest with
REM sleep abnormalities or, more directly, with the intrusion of the dream state into waking. In
subsequent years, a large body of research revealed other abnormalities more frequently present in the
sleep patterns in schizophrenia. Aim of the Work: To highlight the pattern of sleep among schizophrenic
patients and to study the correlation between sleep patterns and symptom profile in schizophrenia.
Subjects and Methods: This was a case control comparative study, by convenient sampling. It is done on
59 participants divided into 30 cases and 29 controls. Results: patients had a lower mean sleep
efficiency, a higher mean sleep latency, a lower mean REM latency and a higher mean arousal
index when compared to controls. Conclusion: An acknowledgement of the potential role of sleep
in the occurrence of psychotic experiences is beginning to be shown. It is now clear from the research
that these two phenomena are connected. The direction of effect is yet to be shown and the
mechanisms by which sleep and psychotic experiences are linked remain to be established, although
there are many plausible different routes for further investigation. Recommendations: Study findings
suggest future directions for causal connections between sleep and psychosis. We would argue that the
high prevalence of sleep problems in patients with psychosis should still become a target in clinical
services, since it is an important problem in its own right, for which effective treatments exist.
