[Polysomnographic evaluation of clinical patients suffering from mood disturbance].
The sleep patterns of sixty patients suffering from mood disturbance, were studied, with mean age of 36.1 +/- 11.3 years ( 12 males, 48 females). These patients were submitted to two nights of nocturnal polysomnographic evaluation; the second night acquired data was employed in the statistics. The following parameters were analyzed: parameters of sleep continuity, parameters of sleep architecture, REM and non-REM sleep parameters. The patients were analyzed in accordance to depression severity, presence of sleep disorders and relevant mood disturbances. The most common diagnosis was dysthymia in 25 cases (41.6%). Descriptive analysis was used to delineate the study. The statistics evaluation used the Fisher exact test and the Kruskal-Wallis statistics heterogeneity test. There was reduction in sleep continuity and increase in REM density, both not statistic significant. Stage 4 sleep showed significant reduction in severely depressed patients (p=0.0253).
