Yurgil et al examine the extent to which self-reported predeployment and deployment-related traumatic brain injury (TBI) confers increased risk of posttraumatic stress disorder (PTSD) when accounting for combat intensity and predeployment mental health symptoms.
This cross-sectional study reports that κ-opioid receptor availability in an amygdala–anterior cingulate cortex–ventral striatal neural circuit mediates the phenotypic expression of trauma-related loss (ie, dysphoria) symptoms and that an activated corticotropin-releasing factor/hypothalamic-pituitary-adrenal axis system may indirectly mediate this association.
This laboratory-based cross-sectional study assesses cue-induced craving for cocaine in adults using both subjective and objective indices of cue-elicited responses.
This cohort study evaluates the association of predeployment heart rate variability with risk of posttraumatic stress disorder after deployment in US Marines.
This Special Communication examines the degree to which modern operationalized diagnostic criteria for schizophrenia reflect the main clinical features of the disorder as described historically by diagnostic experts.
McCarthy et al compare adults with a childhood diagnosis of attention-deficit/hyperactivity disorder (ADHD) and control subjects to determine the specific location of possible ADHD-related differences in resting-state functional connectivity.
Van Dam et al identify structural neural characteristics independently associated with childhood maltreatment, comparing a sample with substance use disorders with a demographically comparable control sample, and they examine the relationship between childhood maltreatment–related structural brain changes and subsequent relapse.
National Survey of American Life data were used to examine the interaction of urbanicity and race/ethnicity on lifetime and 12-month major depressive disorder and mood disorder prevalence for African American women and non-Hispanic white women.
Konova et al examine changes in mesocorticolimbic connectivity with methylphenidate and how connectivity of affected pathways relates to severity of cocaine addiction in 18 nonabstaining individuals with cocaine use disorders.
Kohno and colleagues aimed to determine how methamphetamine-dependent and control participants differed in brain activation during a risky decision-making task, resting-state functional connectivity within mesolimbic and executive control circuits, and the relationships between these measures.
