Processing speed in children treated for brain tumors: effects of radiation therapy and age

The current study examined processing speed in children two years post-treatment for brain tumors (BT) with radiation therapy (RT) compared to those treated with without RT. Participants included 59 children (4–17 years) with BT assessed as part of the Brain Radiation Investigative Study Consortium (BRISC). Processing speed was assessed at two time points: Time1 (3–9 months post-surgery) for 26 children who received whole brain or focal RT (RT group) and 33 treated without RT (no-RT group), and again two years later (Time2) for 42 participants (17 RT, 25 no-RT). Linear mixed effects (LME) regression analyses examined differences in cognitive and motor speed between groups and across visits, with age at Time1 (age1) treated as a moderating variable, and sex and primary tumor size as covariates. No effects for treatment group or visit were found for motor speed (Pegboard) or mean reaction time (Attention Network Task). On the Wechsler Processing Speed Index (PSI), the no-RT group performed better than the RT group, with a group-by-age interaction such that across visits, the difference between the no-RT and RT groups was larger among children who were older at initial treatment (≥10 years) than among those who were younger (<10 years). Cumulative brain injury earlier in life (tumor, surgery, plus RT) may result in greater impact on more complex tasks of cognitive efficiency. Children receiving RT showed reduced processing speed over time, with a larger group difference among those who were over 10 years at treatment.     

The impact of stigma on behavioral health care utilization among active duty service members

This study assessed the relationship between the stigma of seeking psychological help and use of outpatient behavioral health services over a 2-year period among active duty military service members initially referred for neuropsychological evaluation secondary to their histories of mild traumatic brain injury. Although research has examined how stigma predicts proxies for help-seeking (i.e., attitudes towards/intentions to use services), very little research has looked at actual behavior, and studies that do have largely focused on previous use. In this study, we examined the relationship between participants’ stigma and subsequent behavioral health use. Our results indicated that whereas greater self-stigma (i.e., negative self-judgments for seeking psychological help) was associated with attending fewer behavioral health care sessions, public stigma (i.e., perceptions of public attitudes towards people who seek psychological help) was not associated with service use. These findings support the need for addressing the self-stigma associated with seeking behavioral health care.     

Diaphragmatic breathing as treatment for escape‐maintained aggression

Coping skills, such as diaphragmatic breathing, are commonly recommended to help individuals work through challenging situations. We evaluated diaphragmatic breathing as treatment for aggression of three individuals diagnosed with autism spectrum disorder or Angelman syndrome. Functional analysis results demonstrated that each participant engaged in aggression maintained by social‐negative reinforcement. Diaphragmatic breathing treatment without extinction was conducted in a work context and involved prompting diaphragmatic breathing contingent on precursors to aggression; treatment was effective in reducing the rate of aggression for one of three participants. For the two other participants, other reinforcement‐based interventions (differential reinforcement of other behavior or functional communication training with extinction) were necessary to decrease aggression.     

Reengagement With Education: A Multidisciplinary Home-School-Clinic Approach Developed in Australia for School-Refusing Youth

School refusal (SR) can result in decreased academic achievement, impaired social connections, and family stress. Current interventions for SR include behavioral and cognitive-behavioral treatments that are not always effective. Incorporating multidisciplinary work that includes therapeutic and educational interventions may enhance outcomes for youth displaying SR. The In2School program fosters a working partnership between mental health clinicians and teachers. It was designed to meet the needs of young people missing more than 50% of school in the previous 6 weeks due to mental health disorders, including anxiety or depression. This paper reports on an action research study in which the In2School program was piloted. Over a 14-week period, therapeutic and educational interventions were integrated into the learning environment via a transitional classroom to support youths’ return to school. Outcomes of this program are reported for the first cohort of 7 youth. Of these youth, 6 returned to mainstream schooling with attendance levels being maintained for 6 months after completing the intervention. Progress was observed in mental health recovery, quality of life reports, increased social interactions with peers, and positive experiences at school. The preliminary results presented in this paper suggest that a multidisciplinary, home-school-clinic intervention holds promise for helping school-refusing youth to return to school.     

Altered lateralization of dorsal language tracts in 6‐week‐old infants at risk for autism

Altered structural connectivity has been identified as a possible biomarker of autism spectrum disorder (ASD) risk in the developing brain. Core features of ASD include impaired social communication and early language delay. Thus, examining white matter tracts associated with language may lend further insight into early signs of ASD risk and the mechanisms that underlie language impairments associated with the disorder. Evidence of altered structural connectivity has previously been detected in 6‐month‐old infants at high familial risk for developing ASD. However, as language processing begins in utero, differences in structural connectivity between language regions may be present in the early infant brain shortly after birth. Here we investigated key white matter pathways of the dorsal language network in 6‐week‐old infants at high (HR) and low (LR) risk for ASD to identify atypicalities in structural connectivity that may predict altered developmental trajectories prior to overt language delays and the onset of ASD symptomatology. Compared to HR infants, LR infants showed higher fractional anisotropy (FA) in the left superior longitudinal fasciculus (SLF); in contrast, in the right SLF, HR infants showed higher FA than LR infants. Additionally, HR infants showed more rightward lateralization of the SLF. Across both groups, measures of FA and lateralization of these pathways at 6 weeks of age were related to later language development at 18 months of age as well as ASD symptomatology at 36 months of age. These findings indicate that early differences in the structure of language pathways may provide an early predictor of future language development and ASD risk.     

Fourteen‐month‐old infants track the language comprehension of communicative partners

Infants employ sophisticated mechanisms to acquire their first language, including some that rely on taking the perspective of adults as speakers or listeners. When do infants first show awareness of what other people understand? We tested 14‐month‐old infants in two experiments measuring event‐related potentials. In Experiment 1, we established that infants produce the N400 effect, a brain signature of semantic violations, in a live object naming paradigm in the presence of an adult observer. In Experiment 2, we induced false beliefs about the labeled objects in the adult observer to test whether infants keep track of the other person's comprehension. The results revealed that infants reacted to the semantic incongruity heard by the other as if they encountered it themselves: they exhibited an N400‐like response, even though labels were congruous from their perspective. This finding demonstrates that infants track the linguistic understanding of social partners. A video abstract of this article can be viewed at https://youtu.be/pQUv8yFhnbk .     

Parental coping socialization is associated with healthy and anxious early‐adolescents’ neural and real‐world response to threat

The ways parents socialize their adolescents to cope with anxiety (i.e., coping socialization) may be instrumental in the development of threat processing and coping responses. Coping socialization may be important for anxious adolescents, as they show altered neural threat processing and over reliance on disengaged coping (e.g., avoidance and distraction), which can maintain anxiety. We investigated whether coping socialization was associated with anxious and healthy adolescents’ neural response to threat, and whether neural activation was associated with disengaged coping. Healthy and clinically anxious early adolescents (N = 120; M = 11.46 years; 71 girls) and a parent engaged in interactions designed to elicit adolescents’ anxiety and parents’ response to adolescents’ anxiety. Parents’ use of reframing and problem solving statements was coded to measure coping socialization. In a subsequent visit, we assessed adolescents’ neural response to threat words during a neuroimaging task. Adolescents’ disengaged coping was measured using ecological momentary assessment. Greater coping socialization was associated with lower anterior insula and perigenual cingulate activation in healthy adolescents and higher activation in anxious adolescents. Coping socialization was indirectly associated with less disengaged coping for anxious adolescents through neural activation. Findings suggest that associations between coping socialization and early adolescents’ neural response to threat differ depending on clinical status and have implications for anxious adolescents’ coping.
