Abstract Study Objectives Post-traumatic stress disorder (PTSD) and REM sleep behavior disorder (RBD) share some common features including prominent nightmares and sleep disturbances. We aimed to comparatively analyze REM sleep without atonia (RSWA) between patients with chronic PTSD with and without dream enactment behavior (DEB), isolated RBD (iRBD), and controls. Methods In this retrospective study, we comparatively analyzed 18 PTSD with DEB (PTSD+DEB), 18 PTSD without DEB, 15 iRBD, and 51 controls matched for age and sex. We reviewed medical records to determine PTSD clinical features and quantitatively analyzed RSWA. We used non-parametric analyses to compare clinical and polysomnographic features. Results PTSD patients, both with and without DEB, had significantly higher RSWA than controls (all p < 0.025, excepting submentalis phasic duration in PTSD+DEB). Most RSWA measures were also higher in PTSD+DEB than in PTSD without DEB patients (all p <0.025). Conclusions PTSD patients have higher RSWA than controls, whether DEB is present or not, indicating that REM sleep atonia control is abnormal in chronic PTSD. Further prospective studies are needed to determine whether neurodegenerative risk and disease markers similar to RBD might occur in PTSD patients.

Abstract Introduction Post-traumatic stress disorder (PTSD) is characterized by persistent mental and emotional stress following one or more significant physical or psychological traumatic incidents earlier in life. Vivid recall of the events, including traumatic nightmares, and prominent sleep disturbance are usual in PTSD. Previous studies have suggested that PTSD may share some clinical features with idiopathic REM sleep behavior disorder (iRBD) including altered REM sleep without atonia (RSWA) levels. Our group has previously found evidence for altered RSWA control in patients with psychiatric disease, including a pilot sample of PTSD patients with iRBD. We aimed to comparatively analyze RSWA levels between patients with PTSD, PTSD and RBD (PTSD+RBD), iRBD, and controls. Methods We selected 18 PTSD, 18 PTSD+RBD, 15 iRBD, and 51 healthy control patients matched for age and sex from the Mayo Clinic Center for Sleep Medicine’s polysomnography database for RSWA quantification. RSWA amounts in the submentalis (SM) and anterior tibialis (AT) were quantitatively analyzed as a percentage of REM sleep duration, in accordance with previously published methods. Non-parametric analyses were performed to compare RSWA, patient demographics, and PSG data across groups. Significance was set at p < 0.016. Results Patients with PTSD had significantly higher RSWA than controls in all RSWA density measures (p < 0.016 for all). All measures of RSWA, excluding average SM duration, were significantly greater in PTSD+RBD patients compared with controls (p < 0.016 for all). Within the PTSD group, patients on antidepressants did not have significantly higher RSWA in any of the measures. PTSD+RBD patients had significantly higher SM Phasic, AT Any, SM+AT Any, and Tonic RSWA measures than PTSD patients (p < 0.016 for all). Conclusion PTSD patients have significantly higher RSWA than controls, with PTSD+RBD patients having higher RSWA levels than PTSD patients. These data provide the first evidence for abnormal RSWA control in patients with chronic PTSD. This provides evidence of a unique biology in PTSD that could imply a future risk for neurodegenerative disease in PTSD similar to RBD patients. Further prospective studying will need to be performed on patients with PTSD to understand the unique biology. Support

Abstract Study Objectives Sleep problems are a core feature of post-traumatic stress disorder (PTSD). The aim of this study was to find a robust objective measure for the sleep disturbance in patients having PTSD. Methods The current study assessed EEG power across a wide frequency range and multiple scalp locations, in matched trauma-exposed individuals with and without PTSD, during rapid eye movement (REM) and non-REM (NREM) sleep. In addition, a full polysomnographical evaluation was performed, including sleep staging and assessment of respiratory function, limb movements, and heart rate. The occurrence of sleep disorders was also assessed. Results In patients having PTSD, NREM sleep shows a substantial loss of slow oscillation power and increased higher frequency activity compared with controls. The change is most pronounced over right-frontal sensors and correlates with insomnia. PTSD REM sleep shows a large power shift in the opposite direction, with increased slow oscillation power over occipital areas, which is strongly related to nightmare activity and to a lesser extent with insomnia. These pronounced spectral changes occur in the context of severe subjective sleep problems, increased occurrence of various sleep disorders and modest changes in sleep macrostructure. Conclusions This is the first study to show pronounced changes in EEG spectral topologies during both NREM and REM sleep in PTSD. Importantly, the observed power changes reflect the hallmarks of PTSD sleep problems: insomnia and nightmares and may thus be specific for PTSD. A spectral index derived from these data distinguishes patients from controls with high effect size, bearing promise as a candidate biomarker.

There is a lack of research examining secondary stalking and its effect on children who, in many cases, can be direct targets, or secondary survivors, of the stalking of their parent. The present study examines trauma reactions in children of stalking survivors in a Danish sample. It investigates the differences and similarities of such reactions across three age groups. Fifty-seven children were divided into groups depending on their age. The symptoms of the youngest group, 0–6-year-olds, were investigated by way of a maternal diagnostic interview. The two older groups, 7–11- and 12–19-year-olds completed the age-appropriate questionnaires, “Darryl” and “HTQ”, respectively, online. Twenty-two percent of the youngest group met the criteria for Post-Traumatic Stress Disorder (PTSD). Eighty-five percent of the middle age group and 58% of the older age group met PTSD diagnostic criteria. The findings illustrate that reactions to secondary stalking were predominantly within the arousal cluster of PTSD symptomology, with sleep disturbances and irritability commonly reported. The overall prevalence of children meeting PTSD diagnostic criteria in the sample was 56%. Future studies will benefit from larger samples and from knowledge of any pre-existing relationship between parent and stalker.
