The repeated OSA events lead to frequent oxygen desaturations and. PTSD is also associated with obstructive sleep apnea (OSA), concerning 4090 of PTSD patients. Our findings suggest that CNS hypervigilance and hyperarousal, as actual symptoms of GAD, lead to nocturnal insomnia, which in turn may cause-as a consequence of sleep pressure not slept off-diurnal tiredness. Insomnia symptoms, reported by 70 of patients, are often related to increased autonomic arousal and fear of sleep: fear of loss of control and/or of having nightmares (9, 10). ![]() The latter was correlated significantly to the SAS score, but less so to the observer-rated Hamilton anxiety score. EEG mapping during the late morning hours (10.00-12.00 h) demonstrated hypervigilance in the V-EEG, while in the resting recording an increased sleep pressure was detected. In psychophysiology, critical flicker frequency was decreased in the morning, while muscle strength, blood pressure and pulse rate showed no differences. In noopsychic performance, GAD patients did rather well in attention, concentration, attention variability, and numerical memory, while fine-motor activity and reaction time were deteriorated. G47.23 Circadian rhythm sleep disorder, irregular sleep wake type. G47.22 Circadian rhythm sleep disorder, advanced sleep phase type. G47.21 Circadian rhythm sleep disorder, delayed sleep phase type. (ICD-10), comprise the phobic disorders, including agoraphobia with (F40.00) or without panic disorder (F40.01), social phobia (F40.1), and the specific phobias (F40. G47.20 Circadian rhythm sleep disorder, unspecified type. Subjective sleep quality was deteriorated as well, as were well-being, drive, mood, and wakefulness in the morning. Anxiety disorders are the most common type of mental illness in Europe, with a 12-month prevalence of 14 among persons aged 14 to 65. In polysomnography patients demonstrated-as compared with normals-significantly increased wake time during the total sleep period and more early-morning awakening, decreased total sleep and sleep efficiency. After 1 adaptation night, sleep induction, maintainance and architecture were measured objectively by polysomnography, subjective sleep and awakening quality were assessed by self-rating scales and visual analog scales, objective awakening quality was measured by a psychometric test battery, and diurnal tiredness was measured by a 3-min vigilance-controlled EEG (V-EEG) and a 4-min resting EEG mapping. ![]() Forty-four outpatients (25 females, 19 males), aged 24-65 (mean 43) years, diagnosed with non-organic insomnia (ICD-10: F 51.0), related to mild GAD (F 41.1), with a Hamilton anxiety (HAMA) score of 22 +/- 6 and a Zung self-rating anxiety (SAS) score of 37 +/- 6 were included. Objective and subjective sleep and awakening quality as well as daytime vigilance of insomniac patients with generalized anxiety disorder (GAD) were investigated, as compared with normal controls.
