BACKGROUND: Posttraumatic stress disorder (PTSD) can be treated with trauma-focused therapy, although only about 50% of the patients recover on the short-term. In order to improve response rates it is important to identify who will and will not recover from trauma-focused therapy. Although previous studies reported dorsal anterior cingulate cortex (ACC) activity, as well as dorsal cingulum bundle white matter microstructure integrity as markers for the persistence of PTSD symptoms on the short-term, it remains unclear whether these markers also predict long-term PTSD symptom severity...

BACKGROUND: Blood injection injury (BII) phobia is common, with debilitating consequences to the health and well being of many of its sufferers. BII phobia presents with a unique fear response that can involve drops in blood pressure and ultimately fainting. The aim of this study was to provide proof of concept for a line of brief, easy to implement, video-based interventions for reducing phobic avoidance and fears in BII sufferers. One of the interventions was a novel Hypoventilation Respiratory Training (HRT) aimed at reducing the exaggerated ventilation response (hyperventilation) seen in BII phobia...

BACKGROUND: Most studies of brain white matter (WM) in posttraumatic stress disorder (PTSD) have focused on combat trauma, and often were confounded by neurological and substance dependence comorbidity. This study used tract-based spatial statistics (TBSS) and probabilistic tractography to characterize WM microstructure in a mixed-sex community sample of PTSD patients exposed to diverse and multiple traumas, and in trauma-exposed normal comparison (TENC) subjects. METHODS: TBSS compared diffusion measures between 20 adults with DSM-IV PTSD and 17 TENC, using a whole-brain voxel-wise approach...

Posttraumatic stress disorder (PTSD) is common in the general population, yet there are limitations to the effectiveness, tolerability, and acceptability of available first-line interventions. We review the extant knowledge on the effects of marijuana and other cannabinoids on PTSD. Potential therapeutic effects of these agents may largely derive from actions on the endocannabinoid system and we review major animal and human findings in this area. Preclinical and clinical studies generally support the biological plausibility for cannabinoids' potential therapeutic effects, but underscore heterogeneity in outcomes depending on dose, chemotype, and individual variation...

BACKGROUND: Increased psychophysiological reactivity is a hallmark intermediate phenotype of posttraumatic stress disorder (PTSD). Individuals with PTSD exhibit greater skin conductance (SC) responses to trauma scripts than trauma survivors without PTSD. However, trauma scripts require time for development and cannot be easily used in a single visit. Thus, there is a need for a low-cost, easy-to-use, SC recording protocol for PTSD assessment. METHODS: Using a mobile device (eSense) connected to a portable tablet computer, we assessed SC reactivity to a standard trauma interview (STI) in 63 participants recruited from Grady Memorial Hospital in Atlanta, GA, approximately 1 year after trauma exposure...

BACKGROUND: The extent to which earlier age of onset (AO) is a reflection of increased genetic risk for major depression (MD) is still unknown. Previous biometrical research has provided mixed empirical evidence for the genetic overlap of AO with MD. If AO is demonstrated to be relevant to molecular polygenic risk for MD, incorporation of AO as a phenotype could enhance future genetic studies. METHODS: This research estimated the SNP-based heritability of AO in the China, Oxford and VCU Experimental Research on Genetic Epidemiology (CONVERGE) case-control sample (N = 9,854; MD case, n = 4,927)...

OBJECTIVE: We compared the prevalence of receiving depression care between adults with past-year major depressive episodes (depressed) and substance use disorders (SUD) in the United States and their depressed counterparts without SUD. METHOD: Data were from 25,500 adults who participated in the 2008-2014 National Surveys on Drug Use and Health. Descriptive analyses and logistic regression models were applied. RESULTS: During 2008-2014, approximately 55...

BACKGROUND: Many mood disorder patients need analgesics due to increased pain sensitivity. Recent studies have suggested that nonsteroidal anti-inflammatory drugs (NSAIDs) may inhibit antidepressant treatment, which requires replication before clinical recommendations. METHODS: The Clinical and Health Outcomes Initiatives in Comparative Effectiveness for Bipolar Disorder Study randomized participants to 6 months lithium or quetiapine treatment. Use of NSAIDs and paracetamol was assessed throughout the study period and psychopathology measured with the Clinical Global Impression Scale for Bipolar Disorder (CGI-BP) and Bipolar Inventory of Symptoms Scale (BISS)...

BACKGROUND: Early recovery from trauma exposure in youth is poorly understood. This prospective longitudinal study examined the early course of traumatic stress responses in recently trauma-exposed youth, evaluated the revised DSM-5 acute stress disorder (ASD) and PTSD diagnoses and alternative diagnoses, and identified risk factors for persistent traumatic stress. METHOD: Participants were 8- to 17-year-old emergency departments attendees exposed to single incident traumas...

BACKGROUND: We aimed to investigate the relationship between the hippocampal shape deformations and the serum cortisol levels in first-episode and drug-naïve major depression disorder (MDD) patients. METHODS: Thirty first-episode and drug-naïve MDD patients and 40 healthy subjects were recruited. High-resolution T1-weighted imaging and morning blood samples for cortisol measurement were obtained from all MDD patients and healthy subjects. In the hippocampal shape analysis, we compared the hippocampal shape between MDD patients and healthy subjects and evaluated the linear correlation between hippocampal shape deformations and the serum cortisol levels in MDD patients and healthy subjects...

BACKGROUND: Psychiatry has long sought to develop biological diagnostic subtypes based on symptomatic differences. This effort assumes that symptoms reflect, with good fidelity, underlying etiological processes. We address this question for major depression (MD). METHODS: We examine, in twins from a population-based registry, similarity in symptom endorsement in individuals meeting criteria for last-year MD at separate interview waves and in concordant twin pairs...

BACKGROUND: Continuation of antidepressant medication (ADM) after remission is widely used to prevent depressive relapse/recurrence. Little is known about predictors of ADM use in terms of adherence, dosage, and successful tapering. The current study aimed to explore beliefs about the causes of depression and recovery (i.e., causal beliefs) and to examine whether they predict ADM use. METHODS: The data were drawn from a controlled trial and an extension of this trial with additional experience sampling...

BACKGROUND: A small body of research suggests that gene-environment interactions play an important role in the development of bipolar disorder. The aim of the present study is to contribute to this work by exploring the relationship between stressful life events and the catechol-O-methyl-transferase (COMT) Val(158) Met polymorphism in bipolar disorder. METHODS: Four hundred eighty-two bipolar cases and 205 psychiatrically healthy controls completed the List of Threatening Experiences Questionnaire...

BACKGROUND: Insomnia is comorbid with internalizing and externalizing psychiatric disorders. However, the extent to which the etiologic influences on insomnia and common psychopathology overlap is unclear. There are limited genetically informed studies of insomnia and internalizing disorders and few studies of overlap exist with externalizing disorders. METHODS: We utilized twin data from the Virginia Adult Twin Studies of Psychiatric and Substance Use Disorders (total n = 7,500)...

BACKGROUND: Posttraumatic stress disorder (PTSD) has been linked to cognitive decline, but research in women is generally lacking. We examined whether trauma and elevated PTSD symptoms were associated with worse cognitive function in middle-aged civilian women. A secondary objective was to investigate the possible role of depression in the relation of PTSD symptoms to cognitive function. METHODS: The sample comprised 14,029 middle-aged women in the Nurses' Health Study II...

BACKGROUND: Research suggests that the positive affect system may be an important yet underexplored treatment target in anxiety and depression. Existing interventions primarily target the negative affect system, yielding modest effects on measures of positive emotions and associated outcomes (e.g., psychological well-being). The objective of the present pilot study was to evaluate the efficacy of a new transdiagnostic positive activity intervention (PAI) for anxiety and depression. METHOD: Twenty-nine treatment-seeking individuals presenting with clinically impairing symptoms of anxiety and/or depression were randomly allocated to a 10-session protocol comprised of PAIs previously shown in nonclinical samples to improve positive thinking, emotions, and behaviors (e...

BACKGROUND: Maternal depression is associated with increased risk of psychiatric illness in offspring. While risk may relate to depressed mothers' difficulties regulating emotions in the context of interacting with offspring, physiological indicators of emotion regulation have rarely been examined during mother-child interactions-and never among mother-adolescent dyads in which both mother and adolescent have histories of major depressive disorder (MDD). METHODS: We examined changes in high-frequency heart rate variability (HF-HRV), an indicator of parasympathetic (vagal) function that has been related to depression, stress, social engagement, and emotion regulation, in 46 mother-daughter dyads (23 in which both mother and daughter had an MDD history and 23 never-depressed controls)...

BACKGROUND: Existing treatments for depression are known to have only modest effects, are insufficiently targeted, and are inconsistently utilized, particularly in older adults. Indeed, older adults with impaired cognitive control networks tend to demonstrate poor response to a majority of existing depression interventions. Cognitive control interventions delivered using entertainment software have the potential to not only target the underlying cerebral dysfunction associated with depression, but to do so in a manner that is engaging and engenders adherence to treatment protocol...

BACKGROUND: Anxiety disorders are common in youth and cause significant distress and impairment to the individual and family. Oxytocin (OT), a nine amino acid peptide, is implicated in anxiety regulation and modulation of close interpersonal and attachment behavior. Anxiety disorders have been linked to low levels of salivary OT in youth. Research has also linked oxytocinergic functioning to social support, warm contact, and bonding, and indicated that contact with attachment figures stimulates OT response...
