Abstract Introduction The incidence of nightmares and dreams during clinically indicated polysomnography (PSG) is rarely reported. We sought to (1) describe the incidence of nightmares and dreams during PSG, (2) PSG characteristics of nightmares and dreams, and (3) identify clinical correlates. Methods Ninety-three patients undergoing an initial clinically indicated PSG had a post-PSG and...
The incidence and clinical significance of nightmares is difficult to estimate due to varying criteria across studies. The Nightmare Disorder Index (NDI) is a validated measure to evaluate nightmare disorder. However, there is no measure to differentiate trauma-related nightmares compared to trauma associated sleep disorder (TSD), a unique REM parasomnia. The objectives of this study were to...
Trauma associated sleep disorder (TSD) manifests with trauma-related nightmares, disruptive nocturnal behaviors (DNB), and autonomic hyperactivity. Although patients with TSD frequently report DNB, events are infrequently identified during in-lab polysomnography (PSG), possibly due to a sense of safety imparted by a monitored environment. It is unknown if patients with TSD acclimate to the lab...
