Frontal Alpha Asymmetry

The current study examined frontal alpha asymmetry (FAA) as a marker of approach- and avoidance-related prefrontal activity in participants with and without trauma exposure and posttraumatic stress disorder (PTSD). We investigated FAA in an inhibitory control paradigm (threatening vs nonthreatening cues) under 2 levels of cognitive demand (baseline: images constant within a block of trials; vs filtering: images varied randomly within a block) in 3 groups of participants: individuals with PTSD ( n = 16), exposed to trauma but without PTSD ( n = 14), and a control group without PTSD or trauma exposure ( n = 15). Under low demand (baseline), both PTSD and trauma-exposed participants exhibited significantly greater relative left than right frontal brain activity (approach) to threatening than to nonthreatening images. Under high demand (filtering), no FAA differences were found between threatening and nonthreatening images, but PTSD participants revealed more relative left than right FAA, whereas trauma-exposed participants showed reduced left relative right FAA. In all conditions, healthy controls exhibited reduced left relative to right FAA and no differences between threatening and nonthreatening images. Study findings suggest dysfunctional prefrontal mechanisms of emotion regulation in PTSD, but adaptive prefrontal regulation in trauma-exposed individuals without PTSD.

The Impact

Refugees are exposed to multiple traumatic events and postmigration stressors, elevating risk for posttraumatic stress disorder (PTSD), but there is limited research into how these factors affect emotional neural systems. Here, resettled refugees in Australia ( N = 85) completed a functional magnetic resonance imaging scan while viewing fear and neutral faces. We examined the influence of PTSD symptoms, cumulative trauma, and recent postmigration stress on neural reactivity and regional coupling within the refugee sample. Cumulative trauma and postmigration stress but not PTSD symptoms correlated with fear-related brain activity and connectivity. Trauma exposure correlated with stronger activity but overall decreased connectivity in the bilateral posterior insula/rolandic operculum, postcentral gyrus, ventral anterior cingulate cortex, and posterior cingulate gyrus. Postmigration stress correlated with fusiform gyrus hyperactivity and increased connectivity in face-processing networks. Findings highlight the impact of past trauma and recent postmigration stress on fear-related neural responses within refugees over and above PTSD symptoms.

Abstract Background Coronavirus disease 2019 (COVID-19) has affected more than 5 million people around the world and killed more than 300,000 people; thus, it has become a global public health emergency. Our objective was to investigate the mental health of hospitalized patients diagnosed with COVID-19. Methods The PTSD checklist for DSM-5 (PCL-5), Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder Scale (GAD-7), Trauma Exposure Scale, abbreviated version of the Connor–Davidson Resilience Scale (CD-RISC-10), Perceived Social Support Scale (PSSS) and Demographic Questionnaire were used to examine posttraumatic stress disorder (PTSD), depression, anxiety, trauma exposure, resilience and perceived social support among 898 patients who were hospitalized after being diagnosed with COVID-19 in China. The data were analyzed with t tests, one-way ANOVA and multivariable logistic regression analysis. Results The results showed that the prevalence of PTSD, depression and anxiety was 13.2, 21.0 and 16.4%, respectively. Hospitalized patients who were more impacted by negative news reports, had greater exposure to traumatic experiences, and had lower levels of perceived social support reported higher PTSD, depression and anxiety. Conclusions Effective professional mental health services should be designed to support the psychological wellbeing of hospitalized patients, especially those who have severe disease, are strongly affected by negative news and have high levels of exposure to trauma.

The aim of this study was to analyse frequency of embitterment in war veterans with Posttraumatic stress disorder (PTSD) as well as the potential impact of embitterment on the development of chronic PTSD.Patients and methodsIt was analyzed 174 subjects (from Health Center Zivinice/mental health center) through a survey conducted in the period from March 2015 to June 2016, of which 87 war veterans with PTSD and control subjects 87 war veterans without PTSD. The primary outcome measure was the post-traumatic embitterment disorder self-rating scale (PTED Scale) who contains 19 items designed to assess features of embitterment reactions to negative life events. Secondary efficacy measures included the clinician-administered PTSD scale–V (CAPS), the PTSD checklist (PCL), the combat exposure scale (CES), the Hamilton depression rating scale (HAM-D), the Hamilton anxiety rating scale (HAM-A) and the World health organization quality of life scale (WHOQOL-Bref). All subjects were male. The average age of patients in the group war veterans with PTSD was 52.78 ± 5.99. In the control group, average age was 51.42 ± 5.98. Statistical data were analyzed in SPSS statistical program.ResultsComparing the results, t-tests revealed significant difference between group veterans with PTSD and control group (t = −21,21, P < 0.0001). War veterans group with PTSD (X = 51.41, SD = 8,91), control group (X = 14.39, SD = 13.61).ConclusionEmbitterment is frequent in war veterans with PTSD.Disclosure of interestThe authors have not supplied their declaration of competing interest.

AbstractBackgroundThis study examined the structure of the self-concept in a sample of sexual trauma survivors with posttraumatic stress disorder (PTSD) compared to healthy controls using a self-descriptive card-sorting task. We explored whether individuals with PTSD possess a highly affectively-compartmentalized self-structure, whereby positive and negative self-attributes are sectioned off into separate components of self-concept (e.g. self as an employee, lover, mother). We also examined redundancy (i.e. overlap) of positive and negative self-attributes across the different components of self-concept.MethodParticipants generated a set of self-aspects that reflected their own life (e.g. ‘self at work’). They were then asked to describe their self-aspects using list of positive or negative attributes.ResultsResults revealed that, relative to the control group, the PTSD group used a greater proportion of negative attributes and had a more compartmentalized self-structure. However, there were no significant differences between the PTSD and control groups in positive or negative redundancy. Sensitivity analyses demonstrated that the key findings were not accounted for by comorbid diagnosis of depression.ConclusionFindings indicated that the self-structure is organized differently in those with PTSD, relative to those with depression or good mental health.
