| Summary: | All night EEG sleep recordings and clinical evaluations of sleep were performed in order to compare patients with generalized anxiety and normal controls. Patients were selected according to DSM III-R criteria and went through a two weeks phase treatment with placebo before the sleep evaluation. As compared to normals, anxious patients showed a fragmented and superficial sleep with no changes of REM sleep features. Further to disturbances of sleep continuity and duration, they had a higher percentage of wake and stage 2, as well as a reduction of slow wave sleep (SWS) mainly due to a diminished percentage of stage 4. Several EEG sleep measures--related both with the amounts of SWS and sleep duration and continuity--are significantly correlated with symptoms severity. The pathogenic significance of sleep disturbances in generalized anxiety is discussed. |
