Frequency of delayed sleep phase syndrome among hospitalized adolescent psychiatric patients

The sleep phenotype of Borderline Personality Disorder: A systematic review and meta-analysis

“…Reasons for non-inclusion in the meta-analysis included: the reporting of overlapping data (De la Fuente et al, 2004); insufficient data to convert into a common effect size (Bromundt et al, 2013); and the uniqueness of the sleep factor (Dagan, Stein, Steinbock, Yovel, & Hallis, 1998), i.e., it wasn't assessed in a minimum of two studies.…”

“…Most studies reported a psychotropic medication wash-out period (usually of 2 weeks) prior to sleep assessment; five did not report a wash-out period (Huỳnh et al, 2015;Plante, Frankenburg, Fitzmaurice, & Zanarini, 2013b;Selby et al, 2013;Simor, Csóka, & Bódizs, 2010;Taherifard, Abolghasemi, & Hajloo, 2015). Adult samples were used in most studies; only three had adolescent samples (Dagan et al, 1998;Huỳnh et al, 2015;Lereya et al, 2016).…”

“…Three studies indicated irregularities in circadian rhythms in BPD. Individuals with BPD appear more susceptible to delayed sleep phase syndrome: DSPS (Dagan et al, 1998); experience greater variability in Relative Amplitude, i.e., the distribution of activity between day and night (Bromundt et al, 2013); and experience wider sleep variability between weekdays and weekends (Huỳnh et al, 2015).…”

“…Cognitive Behaviour Therapy for insomnia (CBT-I) is an effective treatment (Harvey, 2015), which may help reduce maladaptive sleep related cognitions and potentially aid recovery in BPD (Plante et al, 2013a). Considering the high incidence and potential aetiological role of nightmares in BPD , imagery rescripting and rehearsal (IRR) and imaginal confrontation with nightmare contents (ICNC) may be other evidencebased approaches for some patients (Hansen, Höfling, Kröner-Borowik, Stangier, & Steil, rhythms therapy (Harvey, 2015) are further options for disturbed circadian rhythms in BPD (Bromundt et al, 2013;Dagan et al, 1998;Huỳnh et al, 2015).…”

Circadian rhythms in obsessive–compulsive disorder

“…Weitzman et al (1981) argue, however, that DSPS is the cause and not the result of psychological symptoms in mental disorders, since the treatment of the sleep disorder can lead to a marked improvement in psychological functioning. Other authors support the idea that DSPS precedes and may therefore contribute to the development of mental disorder (Dagan et al 1996(Dagan et al , 1998. With regard to personality disorders, Dagan et al (1996Dagan et al ( , 1998 have suggested that a mismatch between a person's biological clock and the environment may cause social and emotional difficulties.…”
