Premature Aging Among Trauma Survivors-The Longitudinal Implications of Sleep Disruptions on Telomere Length and Cognitive Performance.

OBJECTIVES: Sleep is necessary for brain function as well as physical and cognitive processes. Sleep disruptions, common with aging, intensify among trauma survivors. Moreover, former prisoners-of-war (ex-POWs) often experience premature aging. This study investigates the longitudinal effects of sleep disruptions for ex-POWs in relation to cognitive performance and telomere length as well as between cognition and telomeres. METHOD: This study included Israeli veterans from the 1973 Yom Kippur War who participated in four assessments (1991, 2003, 2008, 2015): (a) ex-POWs (n = 99), and (b) veterans who not were captured (controls) (n = 101). Among both groups, sleep disruptions were assessed using a self-report item in all four assessments. Cognitive performance was assessed using the Montreal Cognitive Assessment (MOCA) and telomere length was assessed via total white blood cells (leukocytes) from whole blood samples using Southern blot, both were measured only among ex-POWs in 2015. We conducted descriptive statistics, repeated measures, correlations, and path analyses. RESULTS: Sleep disruptions were related to lower cognitive performance but not to shorter telomeres. Moreover, cognitive performance and telomere length were found to be related when sleep disruptions were taken into consideration. CONCLUSION: Interpersonal trauma was shown to be a unique experience resulting in sleep disruptions over time, leading to cognitive impairment. These findings highlight the importance of viewing trauma survivors at high-risk for sleep disruptions. Therefore, it is imperative to inquire about sleep and diagnose cognitive disorders to help identify and treat premature aging.

Association of Stress-Related Disorders With Subsequent Neurodegenerative Diseases.

Importance: Posttraumatic stress disorder (PTSD) has been associated with increased risk for dementia. Less is known, however, about other stress-related disorders and their associations with neurodegenerative diseases. Objective: To examine the association between stress-related disorders and risk for neurodegenerative diseases. Design, Setting, and Participants: This population-matched and sibling cohort study was conducted in Sweden using data from nationwide health registers, including the Swedish National Patient Register. Individuals who received their first diagnosis of stress-related disorders between January 1, 1987, and December 31, 2008, were identified. Individuals who had a history of neurodegenerative diseases, had conflicting or missing information, had no data on family links, or were aged 40 years or younger at the end of the study were excluded. Individuals with stress-related disorders were compared with the general population in a matched cohort design; they were also compared with their siblings in a sibling cohort. Follow-up commenced from the age of 40 years or 5 years after the diagnosis of stress-related disorders, whichever came later, until the first diagnosis of a neurodegenerative disease, death, emigration, or the end of follow-up (December 31, 2013), whichever occurred first. Data analyses were performed from November 2018 to April 2019. Exposures: Diagnosis of stress-related disorders (PTSD, acute stress reaction, adjustment disorder, and other stress reactions). Main Outcomes and Measurements: Neurodegenerative diseases were identified through the National Patient Register and classified as primary or vascular. Alzheimer disease, Parkinson disease, and amyotrophic lateral sclerosis were evaluated separately. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) with 95% CIs after controlling for multiple confounders. Results: The population-matched cohort included 61 748 exposed individuals and 595 335 matched unexposed individuals. A total of 44 839 exposed individuals and their 78 482 unaffected full siblings were included in the sibling cohort analysis. The median (interquartile range) age at the start of follow-up was 47 (41-56) years, and 24 323 (39.4%) of the exposed individuals were male. The median (interquartile range) follow-up was 4.7 (2.1-9.8) years. Compared with unexposed individuals, individuals with a stress-related disorder were at an increased risk of neurodegenerative diseases (HR, 1.57; 95% CI, 1.43-1.73). The risk increase was greater for vascular neurodegenerative diseases (HR, 1.80; 95% CI, 1.40-2.31) than for primary neurodegenerative diseases (HR, 1.31; 95% CI, 1.15-1.48). A statistically significant association was found for Alzheimer disease (HR, 1.36; 95% CI, 1.12-1.67) but not Parkinson disease (HR, 1.20; 95% CI, 0.98-1.47) or amyotrophic lateral sclerosis (HR, 1.20; 95% CI, 0.74-1.96). Results from the sibling cohort corroborated results from the population-matched cohort. Conclusions and Relevance: This study showed an association between stress-related disorders and an increased risk of neurodegenerative diseases. The relative strength of this association for vascular neurodegenerative diseases suggests a potential cerebrovascular pathway.

Cognitive and neural facets of dissociation in a traumatized population.

Dissociative phenomena are frequently experienced by psychologically traumatized people. However, little is known about the cognitive profiles of highly dissociative traumatized individuals, and corresponding patterns of neural connectivity when attentional networks are engaged in the context of emotion. One hundred seventeen traumatized women completed the multiscale dissociation inventory (MDI) and neuropsychological testing; MDI scores were used to classify high- and low-dissociative participants. Forty-six participants also underwent fMRI during performance of an attentional control task that incorporates emotionally distracting images (Affective Number Stroop; ANS). Compared to low-dissociative participants, high-dissociative participants demonstrated better performance on an executive functioning task (F1,111 = 4.64, p = .03), worse performance on a task of visual memory (F1,111 = 9.52, p = .003), and similar performance on all other neuropsychological measures. In addition, dissociative symptoms were negatively correlated with functional connectivity between the amygdala and right anterior insula in response to trauma-related ANS trials. These findings indicate that highly dissociative traumatized people experience difficulties with attentional control in the context of emotionally evocative stimuli, but in a neutral context, their overall cognitive profiles are similar to low-dissociative people. Highly dissociative participants also demonstrated weaker connectivity between the amygdala and insula in response to trauma-relevant images. Evocative, trauma-relevant stimuli appear to disrupt neutral networks involved with attention to salient cues and interoception in highly dissociative traumatized individuals.

Optimizing clinical thresholds for PTSD: Extending the DSM-5 preschool criteria to school-age children / Optimizando el umbral clínico para el TEPT: extendiendo criterios del DSM-5 de preescolares a niños de edad escolar

Background/Objective: To examine the effect of using the DSM-5 preschool criteria to diagnose posttraumatic stress disorder (PTSD) in school-age children (ages 7-11). Method: Children exposed to Hurricane Ike (N=327) were assessed for symptoms of PTSD and other trauma-related factors eight months post-disaster. Results: About twice as many children were identified as having PTSD using the DSM-5 preschool criteria compared to the DSM-5 adult criteria. The preschool criteria identified all children diagnosed by the adult criteria and many additional children. Although children who met both the adult and the preschool criteria reported the most functional impairment, children identified by the preschool criteria only reported greater impairment than children not diagnosed. The effect of including impairment in the diagnostic criteria was more marked for the preschool criteria than for the adult criteria. Additionally, PTSD defined by the preschool criteria was significantly associated with more PTSD risk factors than PTSD as defined by the adult criteria. Model fit was similar for both sets of criteria. Conclusions: The preschool criteria may be advantageous for screening for PTSD risk in school-age children. Further research is needed to optimize developmentally-appropriate PTSD criteria for school-age children (AU)

Antecedentes/Objetivo: Examinar el uso los criterios preescolares del DSM-5 para diagnosticar el trastorno de estrés postraumático (TEPT) en niños de edad escolar (7-11 años). Método: Niños expuestos al huracán Ike (N=327) fueron evaluados respecto a los síntomas de TEPT, ocho meses después del desastre. Resultados: Aproximadamente el doble de niños fueron diagnosticados con TEPT usando los criterios preescolares del DSM-5 comparado a los de adultos. Los criterios preescolares identificaron todos los niños diagnosticados usando los criterios de adultos y muchos más. Aunque los niños que cumplieron ambos criterios reportaron el mayor deterioro funcional, los niños identificados solamente por los criterios preescolares reportaron más deterioro que los niños no diagnosticados. El efecto de incluir el deterioro en los criterios diagnósticos fue más intenso para los criterios preescolares. Además, el TEPT definido por los criterios preescolares fue asociado significativamente con más factores de riesgo que TEPT definido por los criterios de adultos. El ajuste del modelo fue similar en ambos conjuntos de criterios. Conclusión: Los criterios preescolares pueden ser útiles para detectar el riesgo de TEPT en niños de edad escolar. Se necesitan más investigaciones para optimizar los criterios de TEPT de acuerdo al nivel de desarrollo para los niños en edad escolar (AU)

Childhood trauma and dimensions of depression: a specific association with the cognitive domain

Objective: To investigate associations between a history of childhood trauma and dimensions of depression in a sample of clinically depressed patients. Methods: A sample of 217 patients from a mood-disorder outpatient unit was investigated with the Beck Depression Inventory, the Hamilton Depression Rating Scale, the CORE Assessment of Psychomotor Change, and the Childhood Trauma Questionnaire. A previous latent model identifying six depressive dimensions was used for analysis. Path analysis and Multiple Indicators Multiple Causes (MIMIC) models were used to investigate associations between general childhood trauma and childhood maltreatment modalities (emotional, sexual, and physical abuse; emotional and physical neglect) with dimensions of depression (sexual, cognition, insomnia, appetite, non-interactiveness/retardation, and agitation). Results: The overall childhood trauma index was uniquely associated with cognitive aspects of depression, but not with any other depressive dimension. An investigation of childhood maltreatment modalities revealed that emotional abuse was consistently associated with depression severity in the cognitive dimension. Conclusion: Childhood trauma, and specifically emotional abuse, could be significant risk factors for the subsequent development of cognitive symptoms of major depression. These influences might be specific to this depressive dimension and not found in any other dimension, which might have conceptual and therapeutic implications for clinicians and researchers alike.

Distress Tolerance: Associations With Posttraumatic Stress Disorder Symptoms Among Trauma-Exposed, Cocaine-Dependent Adults.

The present investigation examined associations between distress tolerance and posttraumatic stress disorder (PTSD) symptoms in a cocaine-dependent sample. Participants were comprised of 138 cocaine-dependent adults (Mage = 45.4, SD = 9.9; 81% male; 76.3% African American) who endorsed trauma exposure, defined according to Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR) PTSD Criterion A. Participants were administered interview-based measures and completed a series of self-report questionnaires. Results indicated that distress tolerance was significantly, incrementally (negatively) associated with PTSD symptom severity, contributing 6.8% of unique variance to the model (p < .001); notably, the overall model explained 44.8% of variance in PTSD symptomatology. Distress tolerance also contributed between 2.7% and 6.8% of unique variance across each of the PTSD symptom clusters (ps < .05). Incremental effects were documented, after accounting for the variance explained by theoretically relevant covariates (i.e., gender, cocaine-use severity, depressive symptoms, trauma-exposure severity). Theoretical and clinical implications are discussed.

Brief report: Moving prevention into schools: The impact of a trauma-informed school-based intervention.

Adolescents in disadvantaged communities have high rates of exposure to stress and trauma, which can negatively impact emotion regulation and executive functioning, increasing likelihood of school problems. This pilot study evaluated RAP Club, a 12-session school-based trauma-informed group intervention co-facilitated by a mental health counselor and young adult community member that utilizes evidence-based cognitive-behavioral and mindfulness strategies. Seventh and eighth graders at two urban public schools serving low-income communities were assigned to receive RAP Club (n = 29) or regular school programming (n = 20). RAP Club improved teacher-rated emotion regulation, social and academic competence, classroom behavior, and discipline. Higher program dose predicted improvements in several teacher-rated outcomes. Student self-report outcomes, however, did not vary by study group or dose. Even students with low baseline depression showed improvement in teacher-rated outcomes following program participation, supporting a model of universal program delivery to all students. Findings suggest RAP Club merits further study.

Examining cultural, social, and self-related aspects of stigma in relation to sexual assault and trauma symptoms.

The current study investigated a model explaining sexual assault victims' severity of trauma symptoms that incorporated multiple stigma constructs. Integrating the sexual assault literature with the stigma literature, this study sought to better understand trauma-related outcomes of sexual assault by examining three levels of stigma-cultural, social, and self. Results showed self-stigma was significantly and positively related to trauma symptom severity. Thus, results revealed that the internalized aspect of stigma served as a mechanism in the relation between sexual assault severity and increased levels of trauma symptom severity, highlighting the importance of assessing self-stigma in women reporting sexual assault experiences.
