RESUMO
BACKGROUND: Prenatal alcohol exposure (PAE) is linked to a variety of neurodevelopmental challenges, including social functioning (SF) and executive functioning (EF) deficits. These deficits present differently across developmental stages from preschool age to adolescence. METHODS: The post hoc analyses described here were conducted on data from 83 preschool-age children with PAE (early childhood group; ages 2.5 to 5.0) and 95 adolescents (49 with PAE, 46 controls; ages 8 to 16). Each child completed EF tasks as part of several prior studies. Parents completed social and communication inventories about their child's abilities. Thirty-three participants from the early childhood group returned for a 4-year follow-up and completed both SF and EF measures. RESULTS: Both the early childhood and adolescent groups with PAE showed deficits in SF and EF. There was a relationship between SF and EF within the adolescent PAE group that was not present in the adolescent control group or the early childhood PAE group. However, at the 4-year follow-up (Mage = 8.45), participants originally in the early childhood PAE group also demonstrated this relationship. CONCLUSIONS: These findings support previous research on EF/SF deficits in adolescents with PAE while also addressing a gap in the literature concerning early childhood research on this topic. Additionally, these findings suggest that the relationship between EF and SF deficits may strengthen throughout development. This line of research highlights potential sensitive periods for SF and EF training in children with PAE and suggests that fetal alcohol spectrum disorders programs consider targeting EF training as a component of social skill interventions.

Fetal alcohol spectrum disorder (FASD) affects 2-5% of the children in the United States. In the preschool age-range, inhibitory deficits frequently manifest as impaired ability to delay gratification, which is associated with deficits in cognitive flexibility in these children. The goal of this longitudinal study was to determine whether the ability to delay gratification in preschool children with FASD is (1) associated with broader manifestations in temperament and behavior; (2) predictive of later inhibitory control, cognitive flexibility and working memory in middle childhood; and (3) predictive of later parent-reported behavioral problems and school functioning in middle childhood. Forty-seven children with FASD, ages 2.5-5 years were administered a delay of gratification task in which they chose between receiving 2 snacks immediately or 10 snacks after waiting for 10 min. Two groups were defined based on a median split of waiting time. Four years later, 29 children completed measures of inhibitory control (Flanker task), cognitive flexibility (Dimensional Change Card Sort Test), and working memory (Stanford-Binet Intelligence Scales), and their parents completed the Child Behavior Checklist as a measure of the child's behavioral problems and school functioning. Children with longer wait times on the delay of gratification task in preschool showed better inhibitory control on the Flanker task in middle childhood and better parent-reported school functioning in English. These findings indicate that early inhibitory capacity persists into middle childhood in those with FASD, and may be a promising target for early intervention to improve later cognitive outcomes in these children.

In this grant report, we describe our project to expand measurement-based psychiatric care across 6 early psychosis treatment teams in Minnesota, and to provide a neuroscience-informed cognitive training and motivation enhancement program for individuals with early psychosis. This project is part of the NIMH Early Psychosis Intervention Network (EPINET) initiative which seeks to link data from treatment centers nationally that offer evidence-based specialty care to persons experiencing early psychosis. Systematic analyses of pooled data collected in EPINET will help inform methods for early psychosis care, psychosis risk factors, and pre-emptive interventions. As part of the national EPINET, our hub (Early Psychosis Intervention-Minnesota, EPI-MINN), will: (1) provide measurement-based care in coordinated specialty care programs for early psychosis, (2) determine whether a structured feedback report provides benefit to stakeholders-service users, family members, and primary clinicians, and (3) explore whether deficits in cognition and motivated behavior-two domains that significantly impact functioning and overall quality of life in early psychosis-can be addressed as key treatment goals by implementing a 12-week mobile intervention. Using a regression discontinuity design, participants will be randomized to the cognitive training and motivational enhancement intervention or to treatment as usual. The intervention consists of neuroscience-informed, computerized auditory and social cognitive training exercises, as well as a mobile app where participants interact with each other and with a motivational coach. Participants will complete assessments at 4 time points: baseline and post-intervention (i.e., at 6 months), and again at 12 and 18 months to test the long-term effects of the intervention. All assessments and interventions in this project can be completed entirely remotely.
RESUMO
BACKGROUND: Despite the high prevalence of fetal alcohol spectrum disorder (FASD), there are few interventions targeting its core neurocognitive and behavioral deficits. FASD is often conceptualized as static and permanent, but interventions that capitalize on brain plasticity and critical developmental windows are emerging. We present a long-term follow-up study evaluating the neurodevelopmental effects of choline supplementation in children with FASD 4 years after an initial efficacy trial. METHODS: The initial study was a randomized, double-blind, placebo-controlled trial of choline vs. placebo in 2-5-year-olds with FASD. Participants include 31 children (16 placebo; 15 choline) seen 4 years after trial completion. The mean age at follow-up was 8.6 years. Diagnoses were 12.9% fetal alcohol syndrome (FAS), 41.9% partial FAS, and 45.1% alcohol-related neurodevelopmental disorder. The follow-up included measures of intelligence, memory, executive functioning, and behavior. RESULTS: Children who received choline had higher non-verbal intelligence, higher visual-spatial skill, higher working memory ability, better verbal memory, and fewer behavioral symptoms of attention deficit hyperactivity disorder than the placebo group. No differences were seen for verbal intelligence, visual memory, or other executive functions. CONCLUSIONS: These data support choline as a potential neurodevelopmental intervention for FASD and highlight the need for long-term follow-up to capture treatment effects on neurodevelopmental trajectories.
