Study objectives: In nightmare etiology, trait and state factors play important roles. However, the interaction of state and trait factors has never been studied in a longitudinal design. Methods: The current sample included 406 pregnant women who were followed up approximately 6 months after giving birth (n = 375) and 4 years later (n = 302). A nightmare frequency scale and several...
Study objectives: To examine the efficacy of imagery rehearsal (IR) combined with cognitive behavioral therapy for insomnia (CBT-I) compared to CBT-I alone for treating recurrent nightmares in military veterans with posttraumatic stress disorder (PTSD). Methods: In this randomized controlled study, 108 male and female United States veterans of the Iraq and Afghanistan conflicts with current,...
Study objectives: Growing evidence suggests that nightmares have considerable adverse effects on waking behavior, possibly by increasing post-sleep negative emotions. Dysphoric reactions to nightmares are one component of nightmare severity for which the neural correlates are unknown. Here, we investigate possible neural correlates of nightmare severity in a sample of individuals who frequently...
Study objectives: Understanding nightmares (NM) and disturbing dreams (DD) in posttraumatic stress disorder (PTSD) has been limited by the unpredictability of these events and their nonappearance in the sleep laboratory. This study used intensive, longitudinal, ambulatory methods to predict morning reports of NM/DD in veterans in whom chronic, severe PTSD was diagnosed. Methods: Participants...
Journal of Clinical Sleep Medicine, Vol. 14, No. 8 August 15, 2018 Creamer and colleagues1 have addressed the very important topic of the high prevalence of clinically significant nightmares (31.2% of 473 military personnel met criteria for nightmare disorder [NDO] and endorsed trouble falling asleep because of bad dreams on at least a weekly basis) among military personnel, with possibly only...
Nightmare disorder affects approximately 4% of adults, occurring in isolation or as part of other disorders such as posttraumatic stress disorder (PTSD), and can significantly impair quality of life. This paper provides the American Academy of Sleep Medicine (AASM) position regarding various treatments of nightmare disorder in adults. A literature search was performed based upon the keywords...
Study objectives: Although nightmares have been associated with suicidal behavior beyond well-known risk factors, the association between nightmares and multiple suicide attempts remains largely unexplored. This study addressed this gap in the literature by examining whether nightmares differentiated between individuals who reported single versus multiple suicide attempts. The individual...
Even though the common diagnostic criteria (ICSD-3, DSM-5) acknowledge that nightmares do not only contain anxiety/fear (definition of the ICD-10) but also other emotions such as grief, disgust, and anger, the definition of a nightmare still focuses on threats to survival, security, or physical integrity. However, empirical studies on nightmare content in larger samples are scarce. The current...
Study objectives: Sleep disturbances are common in United States military personnel. Despite their exposure to combat and trauma, little is known about nightmares in this population. The purpose of this study was to describe the prevalence and associated clinical and polysomnographic characteristics of nightmares in United States military personnel with sleep disturbances. Methods:...
Few studies have addressed dreaming in patients with sleep apnea. We hypothesized that respiratory events and subsequent oxygen desaturation act as an important physiological trigger and may thus influence dream content in patients with a sleep-related breathing disorder. Seventy-six patients (28 women, mean age 54 years, range 20-82) who underwent polysomnography because of suspected sleep...
Despite the considerable prevalence of the nightmare disorder and its burden on the patient, nightmares are underdiagnosed and undertreated, even in sleep centers. A total of 1,125 patients in a sleep center undergoing routine diagnostic procedures for their sleep disorders completed a questionnaire about nightmares. About 20% of the sample indicated an interest in more information about...
Prazosin is increasingly being used off-label to treat nightmares in patients with posttraumatic stress disorder. The literature about the psychiatric adverse effects of prazosin is very limited. We present a case in which low-dose prazosin was associated with nightmares and sleep disturbances in an elderly patient without previously diagnosed mental illness or coexisting environmental risk...
Study objectives: Although nightmares appear to be related to suicidal behaviors, the mechanisms which underpin this relationship are unknown. We sought to address this gap by examining a multiple mediation hypothesis whereby nightmares were predicted to have an indirect effect on suicidal behaviors through perceptions of defeat, entrapment, and hopelessness. Methods: Data were collected from...
Objective: Duration of insomnia symptoms and nightmares are related to suicidal risk in young adults independent of current symptoms of insomnia, nightmares, anxiety, depression, and PTSD. However, this relation has yet to be examined among older adults, despite older adults being at higher risk of suicidal behavior. Further, the current study aims to replicate previous research among younger...
Objectives: Narcolepsy is a disabling disease with a delayed diagnosis. At least 3 years before the disorder identification, several comorbidities can be observed in patients with narcolepsy. The early recognition of narcolepsy symptoms may improve long-term prognosis of the patients. Thus, we aimed to investigate the prevalence of the symptoms associated with narcolepsy and its social and...
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. The present study utilized...
To clarify whether motor behaviors and/ or vocalizations during REM sleep, which do not yet fulfill diagnostic criteria for REM sleep behavior disorder (RBD) and were defined as REM sleep behavioral events (RBEs), correspond to dream enactments. 13 subjects (10 patients with Parkinson disease [PD] and 3 healthy controls) originally identified with RBE in a prospective study (DeNoPa cohort) were...
In this meta-analysis, we compare the short-term efficacy of prazosin vs. IRT on nightmares, sleep quality, and posttraumatic stress symptoms (PTSS). Reference databases were searched for randomized controlled trials using IRT or prazosin for nightmares, sleep disturbance, and/or PTSS. Effect sizes were calculated by subtracting the mean posttest score in the control group from the mean...
Study objectives: To characterize the clinical, polysomnographic and treatment responses of patients with disruptive nocturnal behaviors (DNB) and nightmares following traumatic experiences. Methods: A case series of four young male, active duty U.S. Army Soldiers who presented with DNB and trauma related nightmares. Patients underwent a clinical evaluation in a sleep medicine clinic, attended...
Study objectives: Many studies have reported a positive association between sleep problems and suicidal ideation. Some prospective studies in the elderly have shown that insomnia is a risk factor for suicide death after controlling for other depressive symptoms. However, hypotheses to explain how this risk is mediated have not previously been assessed. We tested the hypothesis that insomnia...
Out-of-body experiences are the phenomena of seeing the image of one's body from an external perspective. We report the case of a patient affected by psychophysiological insomnia who presents hallucinatory phenomenon, successfully treated with haloperidol.We hypothesize that these hallucinations during psychophysiological insomnia are expression of an alteration of specific neurocognitive...
Study objectives: Evidence supports the use of cognitive behavioral therapies for nightmares in trauma-exposed individuals. This randomized clinical trial replicated a study of exposure, relaxation, and rescripting therapy(ERRT) and extended prior research by including broad measures of mental health difficulties, self-reported physical health problems, and quality of life. Additionally,...
The August 2010 issue of Journal of Clinical Sleep Medicine (Vol. 6, No. 4) included an article suggesting treatment recommendations for adult nightmare disorder. Although we appreciate the work by the authors, we were left with three basic concerns about the methodology utilized and results found. First, works providing evidence for some of the treatments were not reported in the original...
Following exposure to traumatic events, approximately 19% of combat veterans develop posttraumatic stress disorder. One of the main symptoms of this mental illness is reexperiencing the trauma, which is commonly expressed in the form of chronic trauma-related nightmares. In these patients, nightmares can fragment sleep, decrease sleep quality, and even cause fear about going to sleep. One...
Prazosin is recommended for treatment of Posttraumatic Stress Disorder (PTSD)-associated nightmares. Level A. Image Rehearsal Therapy (IRT) is recommended for treatment of nightmare disorder. Level A. Systematic Desensitization and Progressive Deep Muscle Relaxation training are suggested for treatment of idiopathic nightmares. Level B. Venlafaxine is not suggested for treatment of...
