Assessment of trauma-related dissociation has been historically challenging given its subjective nature and the lack provider education around this topic. Recent work identified a promising neural biomarker dissociation, representing significant step toward improved assessment identification dissociation. However, it is necessary to better understand clinical factors that may be associated with biomarker. Participants were 65 women histories childhood maltreatment, posttraumatic stress...

Dissociative identity disorder is a posttraumatic, psychobiological syndrome that develops over time during childhood. Despite empirical evidence supporting the validity of this diagnosis and its relation to trauma, remains misunderstood stigmatized condition. This article highlights expert consensus guidelines current research on treatment dissociative disorder. In addition, authors describe Lived Experience Advisory Panel (LEAP), which was designed leverage expertise individuals with...

Discrimination exposure has a detrimental impact on mental health, increasing the risk of depression, anxiety, and posttraumatic stress. The discrimination health is likely mediated by neural processes associated with emotion expression regulation. However, specific that mediate relationship between remain to be determined. present study investigated adolescent stress-elicited brain activity symptoms in young adulthood.

Introduction: Although adolescents often co-use alcohol, cigarettes, and cannabis, little is known about sex racial/ethnic differences in the of these substances. Therefore, this investigation examined cigarette, cannabis a large ethnically diverse group. Methods: Participants were drawn from large, multi-site study three regions United States (N = 4,129; Mage=16.10 years, SD 0.59; 51% female, 49% male; 37% Black, Hispanic, 25% White). categorized into eight mutually exclusive groups based...

Abstract Objectives: A rich body of literature has established the role image distortion and dissatisfaction in development maintenance eating disorders. However, many currently used techniques require explicit comparison person’s to an external stimulus. As schema is a largely unconscious construct, tasks may reflect proxy, rather than itself. Methods: Here we use implicit mental motor imagery (MMI) task interrogate healthy control participants ( N =40) at residential disorder treatment...

Adolescent substance use is linked with negative future outcomes (e.g., depression, anxiety, disorder). Given that the brain undergoes significant maturation during adolescence, this developmental period may represent a time of particular vulnerability to use. Neuroimaging research has largely focused on heavy or binge patterns use; thus, relatively less known about neural impact broader range adolescent Characterizing inform prevention and treatment efforts. The present study investigated...

Exposure to environmental toxicants have serious implications for the general health and well-being of children, particularly during pivotal neurodevelopmental stages. The Environmental Protection Agency's (EPA) Superfund program has identified several areas (Superfund sites) across United States with high levels toxicants, which affect many residents in nearby communities. these been linked changes structure function brain. However, limited research investigated relationship between...

OBJECTIVE: To evaluate the treatment effects of transcranial magnetic (TMS) and direct current stimulation (tDCS) in patients with aphasia (PWA). BACKGROUND: Most studies PWA using TMS tDCS report positive language outcomes. However, degree to which improve response one approach versus another is unknown. Methodological differences between can greatly influence level improvement observed PWA. Treatment may also depend on characteristics related experimental design patient inclusion/exclusion...
