Wake–REM sleep transitions for measuring REM sleep disturbance: Comparison between narcolepsy, idiopathic hypersomnia and healthy controls

This study tested a well‐known but as yet nonoperationalized means for measuring REM sleep disturbance in patients with narcolepsy at night. We retrospectively analyzed polysomnographies of patients with narcolepsy with cataplexy (n= 18), narcolepsy without cataplexy (n= 12), idiopathic hypersomnia (n= 22) and healthy controls (n= 33) with regard to the number of wake–REM sleep transitions as a measurement for REM sleep disturbance at night. We found a significantly higher number of transitions between wake and REM sleep (14.17 ± 2.00) in patients with narcolepsy with cataplexy than in healthy controls (3.70 ± 1.00; p < 0.001) and patients with idiopathic hypersomnia (5.36 ± 1.00; p= 0.001). These results confirm previous findings that REM sleep disturbance is a specific phenomen…

Inference‐Based Therapy for Body Dysmorphic Disorder

AbstractBody dysmorphic disorder (BDD) is a debilitating disorder characterized by an excessive pre‐occupation with an imagined or very slight defect in one’s physical appearance. Despite the overall success of cognitive behavioural therapy (CBT) in treating BDD, some people do not seem to benefit as much from this approach. Those with high overvalued ideation (OVI), for instance, have been shown to not respond well with CBT. The purpose of this study was to evaluate the efficacy of an inference‐based therapy (IBT) in treating BDD. IBT is a cognitive intervention that was first developed for obsessive–compulsive disorder with high OVI, but whose focus on beliefs can also apply to a BDD population. IBT conceptualizes BDD obsessions (e.g., ‘I feel like my head is deformed’) as idio…
