OBJECTIVES: We investigated the potential role of cingulum and uncinate fasciculus integrity in trauma-related neural hypervigilance, indexed by less discrimination between amygdala activation to novel and familiar affective images. PARTICIPANTS: 22 women (mean age 21.7 ± 3.9 years) with a history of trauma, and 20 no-trauma controls (mean age 21.9 ± 4.8 years). MEASURES: Trauma exposure and trauma-related symptoms were assessed during structured clinical interview...

Fear- and stress-induced activity in the amygdala has been hypothesized to influence sensory brain regions through the amygdala's influence on neuromodulatory centers. To directly examine this relationship, we used optical imaging to observe odor-evoked activity in populations of olfactory bulb inhibitory interneurons and of synaptic terminals of olfactory sensory neurons (the olfactory system's primary sensory neurons, which provide the initial olfactory input to the brain) during pharmacological inactivation of amygdala and locus coeruleus (LC) in mice...

BACKGROUND: Studies investigating mechanisms underlying nocebo responses in pain have mainly focused on negative expectations induced by verbal suggestions. Herein, we addressed neural and behavioral correlates of nocebo responses induced by classical conditioning in a visceral pain model. METHODS: In two independent studies, a total of 40 healthy volunteers underwent classical conditioning, consisting of repeated pairings of one visual cue (CS(High) ) with rectal distensions of high intensity, while a second cue (CS(Low) ) was always followed by low-intensity distensions...

This preliminary investigation assessed whether different aspects of personal resiliency improved for youth (7-17 years old) impacted by child sexual abuse (CSA) after completing trauma-focused cognitive behavioral therapy (TF-CBT). The Resiliency Scales for Children and Adolescents (RSCA; Prince-Embury, 2007) were administered to 157 youth before and after participating in TF-CBT with their nonoffending caregivers. Hierarchal regression analyses were performed to ascertain whether pretest RSCA resiliency scores moderated decreases in the posttraumatic stress and self-reported depressive symptoms at posttreatment...

Although childhood shyness is presumed to predict mental health problems in adulthood, no prospective studies have examined these outcomes beyond emerging adulthood. As well, existing studies have been limited by retrospective and cross-sectional designs and/or have examined shyness as a dichotomous construct. The present prospective longitudinal study (N = 160; 55 males, 105 females) examined shyness trajectories from childhood to the fourth decade of life and mental health outcomes. Shyness was assessed using parent- and self-rated measures from childhood to adulthood, once every decade at ages 8, 12-16, 22-26, and 30-35...

OBJECTIVE: The factors underlying the aetiology of fibromyalgia (FM) are largely unknown. According to the generalized hypervigilance hypothesis (GHH), FM patients show excessive attention towards pain stimuli and other sensory events, thereby increasing pain perception and dysfunctional behaviour. We tested this notion by assessing interoceptive accuracy (IA) in FM patients and matched healthy controls. We also tested the hypothesis that FM is characterized by reduced self-regulatory capacity as indexed by heart rate variability (HRV)...

BACKGROUND: Evidence on clitoral reconstruction after female genital mutilation is lacking. CASE: A woman with female genital mutilation experiencing clitoral pain during sex consulted to undergo clitoral reconstruction. The surgery was complicated by a wound infection responsible for severe postoperative pain. Such genital pain made our patient recall the traumatic experience of genital mutilation and experience a relapse of posttraumatic stress disorder symptoms...

Deficits in working memory (WM) and cognitive control processes have been reported in post-traumatic stress disorder (PTSD), in addition to clinical symptoms such as hypervigilance, re-experiencing, and avoidance of trauma reminders. Given the uncontrollable nature of intrusive memories, an important question is whether PTSD is associated with altered control of interference in WM. Some studies also suggest that episodic memory shows a material-specific dissociation in PTSD, with greater impairments in verbal memory and relative sparing of nonverbal memory...

The standard clinical technique for using repetitive transcranial magnetic stimulation (rTMS) for major depressive disorder (MDD) is associated with limited efficacy to date. Such limited efficacy may be due to reliance on scalp-based targeting rather than state-of-the-science methods which incorporate fMRI-guided neuronavigation based on a specific model of neurocircuit dysfunction. In this review, we examine such a specific model drawn from regulatory focus theory, which postulates two brain/behavior systems, the promotion and prevention systems, underlying goal pursuit...

INTRODUCTION: In 2008, the American Academy of Pediatrics recommended that an infant's ability to feed independently be considered a primary consideration for discharge home. To date, NICU healthcare teams have relied on clinical experience as well as descriptive scales to determine a high risk infant's ability to transition safely from tube feeding to oral feeding. The aim of the current case study was to illustrate the clinical utility of nfant(®) Feeding Solution as a noninvasive and objective instrument for determining a neonate's readiness to begin and advance oral feeding...

The purpose of this study was to develop a conceptual framework that captures aspects of health-related quality of life (HRQOL) for caregivers of individuals with military-related traumatic brain injury (TBI). We analyzed qualitative data from nine focus groups composed of caregivers of wounded warriors with a medically documented TBI. Focus group participants were recruited through hospital-based and/or community outreach efforts at the Walter Reed National Military Medical Center, the University of Michigan, and Hearts of Valor support groups (Tennessee and Washington)...

OBJECTIVE: Recent developments in psychometrics enable the application of network models to analyze psychological disorders, such as PTSD. Instead of understanding symptoms as indicators of an underlying common cause, this approach suggests symptoms co-occur in syndromes due to causal interactions. The current study has two goals: (1) examine the network structure among the 20 DSM-5 PTSD symptoms, and (2) incorporate clinically relevant variables to the network to investigate whether PTSD symptoms exhibit differential relationships with suicidal ideation, depression, anxiety, physical functioning/quality of life (QoL), mental functioning/QoL, age, and sex...

INTRODUCTION: There have been suggestions of hypofrontality in cannabis users. To understand cannabis-related differences in decisional processes, Janis and Mann's conflict model of decision making was applied to recreational cannabis smokers who varied in their alcohol use and level of psychological distress. METHOD: An online sample of recreational substance users (114 male, 119 female) completed the Melbourne Decision Making Questionnaire, the Alcohol Use Disorders Identification Test (AUDIT), Kessler's Psychological Distress Scale (K10), and the Severity of Dependence Scale (SDS) for cannabis...

INTRODUCTION: We investigated the genesis and presentation of previously-reported anxiety in disorders of autonomic overexcitation in relation to interoception, body vigilance and trauma to test our hypothesis that patients with the postural tachycardia syndrome (PoTS), vasovagal syncope (VVS) and essential hyperhidrosis (EH) represent atypical anxiety phenotypes in whom affective symptoms are more related to apprehension and vigilance of physiological (interoceptive) feedback than neurotic or trauma-related factors...

It is a fundamental human need to secure and sustain a sense of social belonging. Previous research has shown that individuals who are lonely are more likely than people who are not lonely to attribute humanlike traits (e.g., free will) to nonhuman agents (e.g., an alarm clock that makes people get up by moving away from the sleeper), presumably in an attempt to fulfill unmet needs for belongingness. We directly replicated the association between loneliness and anthropomorphism in a larger sample (N = 178); furthermore, we showed that reminding people of a close, supportive relationship reduces their tendency to anthropomorphize...

BACKGROUND: This study aimed to investigate the effects of fear of pain (FOP) and threat on attentional biases, using eye-tracking methods. METHOD: One hundred and seven undergraduate students were randomized to receive threatening or reassuring information about the cold pressor task; and divided into high and low FOP groups. Participants completed the dot-probe task, while their eye movements were tracked. RESULTS: Results showed that those who received threatening information were less likely to have their first fixation on pain words, particularly affective pain words...

Progress in analyzing and interpreting the concepts of sexual orientation and gender identity in the context of refugee law has contributed to a rise in individuals seeking asylum in such countries as the United States and Canada. However, few studies have examined the victimization experiences of sexual- and gender-identity forced migrants prior to their arrival in North America. This qualitative study used thematic analysis to explore the premigration adult victimization experiences of 26 lesbian, gay, and transgender individuals who obtained refugee, asylee, or withholding-of-removal status in the United States or Canada based on persecution for their sexual orientation and/or gender identity...

Perceived social isolation (PSI), colloquially known as loneliness, is associated with selectively altered attentional, cognitive, and affective processes in humans, but the neural mechanisms underlying these adjustments remain largely unexplored. Behavioral, eye tracking, and neuroimaging research has identified associations between PSI and implicit hypervigilance for social threats. Additionally, selective executive dysfunction has been evidenced by reduced prepotent response inhibition in social Stroop and dichotic listening tasks...
