CONTEXT Chronic nightmares occur frequently in patients with posttraumatic stress disorder (PTSD) but are not usually a primary target of treatment. OBJECTIVE To determine if treating chronic nightmares with imagery rehearsal therapy (IRT) reduces the frequency of disturbing dreams, improves sleep quality, and decreases PTSD symptom severity. DESIGN,(More)
OBJECTIVE The authors investigated the neurobiological basis of poor sleep and daytime fatigue in insomnia. METHOD [(18)F]Fluorodeoxyglucose positron emission tomography was used to assess regional cerebral glucose metabolism of seven patients with insomnia and 20 healthy subjects. RESULTS Compared with healthy subjects, patients with insomnia showed(More)
Sleep disturbances reflect a core dysfunction underlying Posttraumatic Stress Disorder (PTSD). Specifically, disruptive nocturnal behaviors (DNB) may represent PTSD-specific sleep disturbances. The Pittsburgh Sleep Quality Index Addendum for PTSD (PSQI-A) is self-report instrument designed to assess the frequency of seven DNB. The goal of this study was to(More)
OBJECTIVE The aim of this article is to review progress in understanding the mechanisms that underlie circadian and sleep rhythms, and their role in the pathogenesis and treatment of depression. METHODS Literature was selected principally by Medline searches, and additional reports were identified based on ongoing research activities in the authors'(More)
STUDY OBJECTIVES To develop an archive of self-report questions assessing sleep disturbance and sleep-related impairments (SRI), to develop item banks from this archive, and to validate and calibrate the item banks using classic validation techniques and item response theory analyses in a sample of clinical and community participants. DESIGN(More)
The hypothesis that rapid eye movement (REM) sleep disturbances are the hallmark of posttraumatic stress disorder (PTSD), proposed by Ross and colleagues in 1989, has stimulated a wealth of clinical, preclinical, and animal studies on the role of sleep in the pathophysiology of PTSD. The present review revisits this influential hypothesis in light of(More)
The aim of the present study was to evaluate severity of sleep disturbances in a group of 105 individuals presenting with complicated grief (CG) accompanied or not by comorbid depression and/or posttraumatic stress disorder (PTSD). A sample of 105 adults meeting criteria for CG was included in this study. All completed the Pittsburgh Sleep Quality Index(More)
Sleep disturbances (SD) are a core clinical feature of PTSD. The goal of the study was to determine the influence of patient-related characteristics, disorder-related characteristics, and psychiatric comorbidity on the severity of SD in PTSD outpatients (n = 367) who were not recruited for a sleep study. Increased severity of SD paralleled increasing(More)
BACKGROUND Nightmares are common in posttraumatic stress disorder (PTSD), but they also frequently occur in idiopathic form. Findings associated with sleep disturbances in these two groups have been inconsistent, and sparse for idiopathic nightmares. The aim of the present study was to investigate whether sleep anomalies in PTSD sufferers with frequent(More)
BACKGROUND Chronic insomnia is a common health problem with substantial consequences in older adults. Cognitive behavioral treatments are efficacious but not widely available. The aim of this study was to test the efficacy of brief behavioral treatment for insomnia (BBTI) vs an information control (IC) condition. METHODS A total of 79 older adults (mean(More)
