Script-driven imagery was used to assess nightmare imagery-evoked physiological-emotional reactivity (heart rate, skin conductance, facial electromyogram, subjective ratings) in trauma-exposed persons suffering from chronic nightmares. Goals were to determine the efficacy of nightmare imagery to evoke physiological-emotional reactivity, correlates (mental health, nightmare characteristics) of r...

Interest in the treatment of nightmares has greatly increased over the last several years as research has demonstrated the clinical significance of nightmare disorder. This paper provides an overview of nightmare disorder, its clinical relevance, and the leading treatments that are available. In particular, the paper defines nightmare disorder and then summarize the recent literature examining ...

Nightmares are a common and serious problem in psychotherapeutic practice, although they are seldom considered as independent mental disorders. There are some promising approaches to the treatment of nightmares, notably Imagery Rehearsal Therapy, a cognitive-restructuring treatment. The core of this approach is the modification of the nightmare script and repeated imagination of the new script....

BACKGROUND Nightmares are rare in the sleep laboratory, even in patients with posttraumatic stress disorder for whom nightmare complaints are diagnostic. Nevertheless, it is possible that laboratory conditions do not preclude the observation of telltales-nightmare-related modifications of tonic sleep-given sufficiently large samples. METHODS Sixty-three unmedicated, nonapneic Vietnam combat v...

OBJECTIVE Nightmares are a robust and modifiable predictor of increased suicidality and poor psychiatric outcomes, yet nightmare screening and treatment remain rare, even in sleep centers. This paper aims to examine what proportion of nightmare sufferers have discussed nightmares with a healthcare provider, as well as possible explanations for low rates of nightmare complaints. METHODS The pr...

Retrospective measurements underestimate nightmare frequency, but little is known about how retrospective duration and attention for nightmares may affect this process. This study evaluates the differences between two retrospective durations, a prospective log, and a retrospective estimate after keeping this log. Forty-nine participants completed the SLEEP-50, kept a nightmare log, and estimate...

Cognitive-behavioral treatments (CBTs) that target nightmares are efficacious for ameliorating self-reported sleep problems and psychological distress. However, it is important to determine whether these treatments influence objective markers of nightmare-related fear, because fear and concomitant physiological responses could promote nightmare chronicity and sleep disturbance. This randomized,...

Although a growing body of research indicates that frequent nightmares are related to impaired sleep regulation, the pathophysiology of nightmare disorder is far from being fully understood. We examined the relative spectral power values for NREM and REM sleep separately in 19 individuals with nightmare disorder and 21 healthy controls, based on polysomnographic recordings of the second nights'...

Sexual assault survivors with post-traumatic stress disorder (PTSD) were assessed for frequency of nightmares, measured retrospectively on the Nightmare Frequency Questionnaire (NFQ) and prospectively on nightmare dream logs (NLOG). Retrospective frequency was extremely high, averaging occurrences every other night and an estimated number of nightmares greater than five per week. Test-retest re...

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,...
