A memory-based model of posttraumatic stress disorder: evaluating basic assumptions underlying the PTSD diagnosis.
(Psychol Rev, 2008-10)In the mnemonic model of posttraumatic stress disorder (PTSD), the current memory of a negative event, not the event itself, determines symptoms. The model is an alternative to the current event-based etiology of PTSD represented ... -
A qualitative analysis of the Three Good Things intervention in healthcare workers.
(BMJ open, 2017-06-13)BACKGROUND:Intensive care unit (ICU) personnel have an elevated prevalence of job-related burn-out and post-traumatic stress disorder, which can ultimately impact patient care. To strengthen healthcare workers' skills to ... -
Age-dependent white matter disruptions after military traumatic brain injury: Multivariate analysis results from ENIGMA brain injury.
(Human brain mapping, 2022-06)Mild Traumatic brain injury (mTBI) is a signature wound in military personnel, and repetitive mTBI has been linked to age-related neurogenerative disorders that affect white matter (WM) in the brain. However, findings of ... -
Allopregnanolone Levels Are Inversely Associated with Self-Reported Pain Symptoms in U.S. Iraq and Afghanistan-Era Veterans: Implications for Biomarkers and Therapeutics.
(Pain Med, 2016-01)BACKGROUND AND OBJECTIVES: Pain symptoms are common among Iraq/Afghanistan-era veterans, many of whom continue to experience persistent pain symptoms despite multiple pharmacological interventions. Preclinical data suggest ... -
Altered resting-state functional connectivity of basolateral and centromedial amygdala complexes in posttraumatic stress disorder.
(Neuropsychopharmacology, 2014-01)The amygdala is a major structure that orchestrates defensive reactions to environmental threats and is implicated in hypervigilance and symptoms of heightened arousal in posttraumatic stress disorder (PTSD). The basolateral ... -
Amygdala volume changes in posttraumatic stress disorder in a large case-controlled veterans group.
(Arch Gen Psychiatry, 2012-11)CONTEXT: Smaller hippocampal volumes are well established in posttraumatic stress disorder (PTSD), but the relatively few studies of amygdala volume in PTSD have produced equivocal results. OBJECTIVE: To assess a large cohort ... -
Amygdala, Hippocampus, and Ventral Medial Prefrontal Cortex Volumes Differ in Maltreated Youth with and without Chronic Posttraumatic Stress Disorder.
(Neuropsychopharmacology, 2016-02)Posttraumatic stress disorder (PTSD) is considered a disorder of recovery where individuals fail to learn and retain extinction of the traumatic fear response. In maltreated youth, PTSD is common, chronic, and associated ... -
An epigenome-wide association study of posttraumatic stress disorder in US veterans implicates several new DNA methylation loci.
(Clinical epigenetics, 2020-03)<h4>Background</h4>Previous studies using candidate gene and genome-wide approaches have identified epigenetic changes in DNA methylation (DNAm) associated with posttraumatic stress disorder (PTSD).<h4>Methods</h4>In this ... -
Autobiographical memory for stressful events: the role of autobiographical memory in posttraumatic stress disorder.
(Conscious Cogn, 2011-09)To provide the three-way comparisons needed to test existing theories, we compared (1) most-stressful memories to other memories and (2) involuntary to voluntary memories (3) in 75 community dwelling adults with and 42 without ... -
Changes in neuroticism following trauma exposure.
(J Pers, 2014-04)Using longitudinal data, the present study examined change in midlife neuroticism following trauma exposure. Our primary analyses included 670 participants (M(age) = 60.55; 65.22% male, 99.70% Caucasian) who completed the ... -
Confidence, not consistency, characterizes flashbulb memories.
(Psychol Sci, 2003-09)On September 12, 2001, 54 Duke students recorded their memory of first hearing about the terrorist attacks of September 11 and of a recent everyday event. They were tested again either 1, 6, or 32 weeks later. Consistency ... -
Cumulative exposure to traumatic events in older adults.
(Aging Ment Health, 2014)OBJECTIVES: The present study examined the impact of cumulative trauma exposure on current posttraumatic stress disorder (PTSD) symptom severity in a nonclinical sample of adults in their 60s. The predictive utility of cumulative ... -
Demographic, maltreatment, and neurobiological correlates of PTSD symptoms in children and adolescents.
(J Pediatr Psychol, 2010-06)OBJECTIVE: To examine the relationships of demographic, maltreatment, neurostructural and neuropsychological measures with total posttraumatic stress disorder (PTSD) symptoms. METHODS: Participants included 216 children ... -
Effects of chronic mild traumatic brain injury on white matter integrity in Iraq and Afghanistan war veterans.
(Human Brain Mapping, 2013-11)Mild traumatic brain injury (TBI) is a common source of morbidity from the wars in Iraq and Afghanistan. With no overt lesions on structural MRI, diagnosis of chronic mild TBI in military veterans relies on obtaining an ... -
Emotion and autobiographical memory: considerations from posttraumatic stress disorder.
(Phys Life Rev, 2010-03) -
Examining the factor structure of the Connor-Davidson Resilience Scale (CD-RISC) in a post-9/11 U.S. military veteran sample.
(Assessment, 2014-08)The present study examined the structural validity of the 25-item Connor-Davidson Resilience Scale (CD-RISC) in a large sample of U.S. veterans with military service since September 11, 2001. Participants (N = 1,981) completed ... -
Factors related to posttraumatic stress disorder in adolescence.
(Trauma Violence Abuse, 2012-07)Studies of posttraumatic stress disorder (PTSD) in adolescence published from 2000 to 2011 indicate that adolescents are at greater risk of experiencing trauma than either adults or children, and that the prevalence of PTSD ... -
Fear learning circuitry is biased toward generalization of fear associations in posttraumatic stress disorder.
(Transl Psychiatry, 2015-12-15)Fear conditioning is an established model for investigating posttraumatic stress disorder (PTSD). However, symptom triggers may vaguely resemble the initial traumatic event, differing on a variety of sensory and affective ... -
Flashbulb memories and posttraumatic stress reactions across the life span: age-related effects of the German occupation of Denmark during World War II.
(Psychol Aging, 2006-03)A representative sample of older Danes were interviewed about experiences from the German occupation of Denmark in World War II. The number of participants with flashbulb memories for the German invasion (1940) and capitulation ... -
