Abstract: Sleep disturbances are often viewed as a secondary symptom of post-traumatic stress disorder (PTSD), thought to resolve once PTSD has been treated. Specific screening, diagnosis and treatment of sleep disturbances is therefore not commonly conducted in trauma centres. However, recent evidence shows that this view and consequent practices are as much unhelpful as incorrect. Several sleep disorders-nightmares, insomnia, sleep apnoea and periodic limb movements-are highly prevalent in PTSD, and several studies found disturbed sleep to be a risk factor for the subsequent development of PTSD. Moreover, sleep disturbances are a frequent residual complaint after successful PTSD treatment: a finding that applies both to psychological and pharmacological treatment. In contrast, treatment focusing on sleep does alleviate both sleep disturbances and PTSD symptom severity. A growing body of evidence shows that disturbed sleep is more than a secondary symptom of PTSD-it seems to be a core feature. Sleep-focused treatment can be incorporated into any standard PTSD treatment, and PTSD research needs to start including validated sleep measurements in longitudinal epidemiologic and treatment outcome studies. Further clinical and research implications are discussed, and possible mechanisms for the role of disturbed (REM) sleep in PTSD are described.

Abstract: The DSM-IV-TR definition of nightmares-extremely frightening dreams from which the person wakes up directly-is unnecessarily narrow. Other emotions (anger, grief) have also been reported in nightmares, and direct awakening from a bad dream seems to be unrelated to increased distress. In addition, assessment of nightmares is problematic. Polysomnographic recordings have an ameliorating effect on nightmare frequency, retrospective measurements tend to underestimate nightmare frequency, and persons with frequent nightmares may feel reluctant to fill out (daily) prospective measurements. For studying nightmares, it is necessary to distinguish idiopathic nightmares from posttraumatic nightmares, which are part of a posttraumatic stress reaction or disorder that may result from experiencing a traumatic event. Both types of nightmares have been associated with an elevated level of periodic limb movements, although only posttraumatic nightmares seem to be related to more and longer nocturnal awakenings. Nightmares have also been repeatedly associated with the general level of psychopathology, or the so-called personality factor neuroticism. Nightmare distress, the impact on daily functioning caused by nightmares, may function as a mediating variable. Several studies in the last decades have shown that nightmares can be treated with several cognitive-behavioral techniques. The cognitive-restructuring technique imagery rehearsal therapy is the treatment of choice for nightmares, although a randomized controlled trial with an attention control-group has not yet been carried out. Nightmares are more than a symptom of a larger (anxiety) syndrome and need to be viewed from a sleep medicine perspective: nightmares are a highly prevalent and separate sleep disorder that can and should receive specific treatment.

Abstract: BACKGROUND: The goal of this pilot study was to evaluate the effects of the cognitive-restructuring technique 'lucid dreaming treatment' (LDT) on chronic nightmares. Becoming lucid (realizing that one is dreaming) during a nightmare allows one to alter the nightmare storyline during the nightmare itself. METHODS: After having filled out a sleep and a posttraumatic stress disorder questionnaire, 23 nightmare sufferers were randomly divided into 3 groups; 8 participants received one 2-hour individual LDT session, 8 participants received one 2-hour group LDT session, and 7 participants were placed on the waiting list. LDT consisted of exposure, mastery, and lucidity exercises. Participants filled out the same questionnaires 12 weeks after the intervention (follow-up). RESULTS: At follow-up the nightmare frequency of both treatment groups had decreased. There were no significant changes in sleep quality and posttraumatic stress disorder symptom severity. Lucidity was not necessary for a reduction in nightmare frequency. CONCLUSIONS: LDT seems effective in reducing nightmare frequency, although the primary therapeutic component (i.e. exposure, mastery, or lucidity) remains unclear.

Abstract: Objectives were to assess the relations of various sleep complaints with depressive and anxiety complaints in a non-clinical population. Four-hundred-and-two randomly approached adults received three questionnaires. Results showed a high interrelatedness between sleep and depressive/anxiety complaints. Both assessment and treatment of depressive and anxiety complaints should address sleep problems.
