“…Supporting this link are findings that individuals with ADHD manifest response inhibition deficits on tasks such as the Go/No-Go and Stop-Signal Tasks (Patros et al, 2015). Not surprisingly, PTSD and trauma exposure have also been associated with greater impulsivity, further supporting the role of attention deficits in this disorder (Netto et al, 2016). For example, PTSD has been linked to increases in reckless driving (Lapham et al, 2006), risky sexual behavior (Green et al, 2005), substance use (Jakupcak et al, 2007), self-harm (Kimbrel et al, 2014) and aggressive behavior (Jakupcak et al, 2007).…”

Posttraumatic Stress Disorder (PTSD) is associated with alterations in attention at the behavioral and neural levels. However, there are conflicting findings regarding the specific type of attention impairments present in PTSD, as the commonly used tests of attention do not isolate the mechanisms behind attention abnormalities, and the constructs measured do not map onto the neurocircuits governing attention. Here, we review the literature on attention processing in PTSD and offer directions for future research to clarify these unanswered questions. First, using instruments that allow assessment of behavioral and neurophysiological attention components will be necessary to understand attention deficits in PTSD. Second, focus on intra-individual variability in addition to assessment of central tendency may help clarify some of the mixed findings. Third, longitudinal studies on attentional processes are warranted to determine how attention contributes to the development and maintenance of PTSD. Integration of behavioral and neural measures of attention will be useful in understanding the pathophysiology of PTSD.

“…A cut‐off score of 38 was defined to classify whether an adolescent had fulfilled diagnostic criteria for PTSD or not (Tian, Wong, Li, & Jiang, ). The PCL‐C has been shown to have high internal consistence (Cook, Elhai, & Arean, ), and has been commonly used with adolescents (Li, Fan, Hu, Ran, & Fang, ; Liu et al, ; Netto et al, ; Ran et al, ).…”

Indirect evidences suggested associations of estrogen receptor alpha (ESR1) with post-traumatic stress disorder (PTSD). However, the relationship between rs9340799 on ESR1 gene and PTSD has not been reported yet. The present study was to explore the longitudinal changes of prevalence and severity of PTSD in adolescents with different genotypes of rs9340799 after the 2008 Wenchuan earthquake. Social-environmental factors were collected by questionnaires in 465 high school students. Variants of rs9340799 were determined by polymerase chain reaction-restriction fragment length polymorphism analyses and verified by DNA sequencing. PTSD symptoms were assessed by PTSD Checklist-Civilian Version (PCL-C) at 6, 12, and 18 months after the earthquake. The female AA homozygotes had a trend of higher prevalence of PTSD and significantly higher PCL-C scores than the female G allele carriers at 6 months after the earthquake. The female students had higher prevalence of PTSD and higher PCL-C scores than the male subjects at 6 months in the AA homozygotes, but not in the G allele carriers. Consecutive decreases in PCL-C scores were observed only in the female AA homozygotes. Only in the female, the AA genotype was the risk factor and predictor of PCL-C scores at 6 months. Potential factors of PTSD prevalence and predictors of PCL-C scores were different between the AA homozygotes and G allele carriers at different time during the follow-up. These results suggest gene-environment interactions may occur among rs9340799 and social-environmental factors, and influence the development and natural rehabilitation of PTSD in the course after stressed by the earthquake.

Impulsivity is opposed to reflexivity as a cognitive style. This study investigated the frequency distribution of impulsivity in Bulgarian students, as well as some socio-demographic (gender, age, and some scientific areas – social sciences and humanities, as well as sport) differences in impulsivity. Impulsivity opposed to Reflexivity was assessed by means of a sub-scale of the computerized test method Attitude towards Work from Vienna Test System among 141 Bulgarian students. The results revealed slightly more frequent impulsivity than reflexivity in Bulgarian students, but not any gender, age or scientific areas main effects on impulsivity/reflexivity, only their interaction effect, such that younger male students in sport were more impulsive than older male students in sport. A minor trend was found reflexivity to increase with longer sports practice. These findings may indicate the quality of taken decisions in youth.
