RESUMEN
Children and youths diagnosed with FASD may experience a range of adverse health and social outcomes. This cross-sectional study investigated the characteristics and outcomes of children and youths diagnosed with FASD between 2015 and 2018 at the Sunny Hill Centre in British Columbia, Canada and examined the relationships between prenatal substance exposures, FASD diagnostic categories, and adverse health and social outcomes. Patient chart data were obtained for 1187 children and youths diagnosed with FASD and analyzed. The patients (mean age: 9.7 years; range: 2-19) had up to 6 physical and 11 mental health disorders. Prenatal exposure to other substances (in addition to alcohol) significantly increased the severity of FASD diagnosis (OR: 1.18): the odds of FASD with sentinel facial features (SFF) were 41% higher with prenatal cigarette/nicotine/tobacco exposure; 75% higher with exposure to cocaine/crack; and two times higher with exposure to opioids. Maternal mental health issues and poor nutrition also increase the severity of FASD diagnosis (60% and 6%, respectively). Prenatal exposure to other substances in addition to alcohol significantly predicts involvement in the child welfare system (OR: 1.52) and current substance use when adjusted for age (aOR: 1.51). Diagnosis of FASD with SFF is associated with an increased number of physical (R2 = 0.071, F (3,1183) = 30.51, p = 0.000) and mental health comorbidities (R2 = 0.023, F (3,1185) = 9.51, p = 0.000) as compared to FASD without SFF adjusted for age and the number of prenatal substances. Screening of pregnant women for alcohol and other substance use, mental health status, and nutrition is extremely important.

BACKGROUND: Fetal alcohol spectrum disorders (FASD) are associated with neurodevelopmental challenges leading to difficulties with everyday life tasks. The Families Moving Forward (FMF) Program teaches caregivers to use positive behavior support (PBS), integrated with other techniques. However, it is unknown how caregivers retain and use these PBS strategies after the intervention. METHODS: About 4.5 months after completing the FMF Program, twenty-three caregivers of children with FASD aged 4-12 were interviewed about problem behaviors targeted during the FMF Program and their continued use of PBS strategies. Interviews were recorded and coded thematically by a five-coder team. Higher-level pattern codes were developed to facilitate themes across descriptive codes. RESULTS: Caregivers commonly targeted task incompletion and rule breaking, and problem behaviors were often complex or combined. Caregivers identified environmental and interpersonal triggers for problem behavior. They used many accommodations to prevent problem behaviors, most often related to task or environment simplification. Caregivers also used consequence-based strategies. CONCLUSIONS: This study is the first to characterize caregivers' use of PBS strategies for children with FASD using mixed methods. Problem behaviors such as rule breaking were more difficult to target. Caregivers found most success when using a combination of multiple different accommodations per problem behavior. WHAT THIS PAPER ADDS: This is the first study to use mixed methods to characterize how caregivers of children with fetal alcohol spectrum disorders (FASD) use positive behavior support (PBS) strategies to target problem behavior after completion of the empirically validated Families Moving Forward (FMF) Program. Among other techniques involved in the FMF Program, PBS strategies are taught to caregivers and are used to target two distinct, caregiver-identified problem behaviors. This data provides essential information about behaviors responsive to PBS supports, for children with FASD, to inform clinical intervention and research. Notably, multiple problem behaviors often occurred together, emphasizing complexity of behavior challenges in this population and the resulting need for individualized supports. This study is the first to describe commonly observed triggers (antecedents) and commonly used supports (accommodations) from the perspective of caregivers of children with FASD. Importantly, results indicate that use of a wide variety of accommodations, or antecedent-based strategies, are effective in supporting behavior in children with FASD. However, success was most common when caregivers used multiple accommodations for any given concerning behavior. Findings represent 'real-world' strategies caregivers use to support adaptive behavior in their children several months after completion of the FMF Program, suggesting these strategies are applicable to clinical practice.

This study compared the Behavior Assessment System for Children-Third Edition (BASC-3) to the Child Behavior Checklist (CBCL) and the Vineland Adaptive Behavior Scales-Third Edition (VABS-3) in children with and without histories of prenatal alcohol exposure. Data were collected from Collaborative Initiative on Fetal Alcohol Spectrum Disorders Phase 4 sites. Caregivers rated their child's behavior using three questionnaires: BASC-3, CBCL, and VABS-3. BASC-3 Adaptive Skills, Externalizing Problems, and Internalizing Problems scores were correlated with comparable scores from the CBCL (Externalizing and Internalizing Problems) and VABS-3 (Adaptive Skills) both within and across groups. Sensitivity, specificity, and positive and negative predictive values were calculated for the BASC-3. BASC-3 sensitivity rates were 78.1%, 80.5%, and 47.0% and specificity rates were 79.4%, 80.4%, and 81.5% for Adaptive Skills, Externalizing Problems, and Internalizing Problems, respectively. Positive predictive values were 87.1%, 88.0%, and 81.9% and negative predictive values were 67.0%, 69.8%, and 46.3% for Adaptive Skills, Externalizing Problems, and Internalizing Problems, respectively. Results replicated previous reports of behavioral and adaptive difficulties in children with prenatal alcohol exposure. These findings provide support for using the BASC-3 in this population.

INTRODUCTION: A child's oral health impacts their development and quality of life. Children who live with fetal alcohol spectrum disorder (FASD) face barriers to dental care combined with poorer oral health outcomes. However, how this affects their oral health-related quality of life (OHRQoL) is largely unknown. Thus, the aim of this study is to examine the OHRQoL of children living with FASD. METHODS: This cross-sectional survey used the Child Oral Health Impact Profile-Short Form-19 (COHIP-SF-19) to evaluate the OHRQoL quality of life of children (aged 8 to 15) living with FASD, compared to healthy controls. RESULTS: A total of 332 children (or their caregivers) completed the survey. The survey results showed that children living with FASD reported significantly more untreated dental conditions. The majority of children in the control group experienced a low impact across the majority of COHIP-SF-19 domains. However, children living with FASD experienced significantly higher impact scores related to oral health, functional well-being, and social-emotional well-being. CONCLUSION: The results demonstrated that children who live with FASD have a poorer OHRQoL. Overall, more investigation is necessary to identify the best ways to improve the OHRQoL of children living with FASD.

Prenatal alcohol exposure (PAE), the leading known cause of childhood developmental disability, has long-lasting effects extending throughout the lifespan. It is well documented that children prenatally exposed to alcohol have difficulties inhibiting behavior and sustaining attention. Thus, the Sustained Attention to Response Task (SART), a Go/No-go paradigm, is especially well suited to assess the behavioral and neural functioning characteristics of children with PAE. In this study, we utilized neuropsychological assessment, parent/guardian questionnaires, and magnetoencephalography during SART random and fixed orders to assess characteristics of children 8-12 years old prenatally exposed to alcohol compared to typically developing children. Compared to neurotypical control children, children with a Fetal Alcohol Spectrum Disorder (FASD) diagnosis had significantly decreased performance on neuropsychological measures, had deficiencies in task-based performance, were rated as having increased Attention-Deficit/Hyperactivity Disorder (ADHD) behaviors and as having lower cognitive functioning by their caretakers, and had decreased peak amplitudes in Broadmann's Area 44 (BA44) during SART. Further, MEG peak amplitude in BA44 was found to be significantly associated with neuropsychological test results, parent/guardian questionnaires, and task-based performance such that decreased amplitude was associated with poorer performance. In exploratory analyses, we also found significant correlations between total cortical volume and MEG peak amplitude indicating that the reduced amplitude is likely related in part to reduced overall brain volume often reported in children with PAE. These findings show that children 8-12 years old with an FASD diagnosis have decreased amplitudes in BA44 during SART random order, and that these deficits are associated with multiple behavioral measures.

BACKGROUND: The term Fetal Alcohol Spectrum Disorders (FASD) describes a range of neurodevelopmental conditions, the direct result of prenatal alcohol exposure. FASD encompasses a range of behavioural, cognitive and sleep patterns that are sometimes indiscernible from other neurodevelopmental conditions, one in particular being Autism Spectrum Disorders (ASD). This study aimed to provide a comparison of behavioural, cognitive, affect-related and sleep profiles in children aged between 6 and 15 years with diagnoses of FASD or ASD, in contrast to typically developing (TD) children. METHODS: We compared 29 children with FASD, 21 children with ASD and 45 typically developing (TD) children on parental-reported questionnaires measuring behaviour and executive functioning: the Child Behaviour Checklist (CBCL), the Spence Children's Anxiety Scale (SCAS) and the Behaviour Rating Inventory for Executive Function (BRIEF). Additionally, parents completed the Children's Sleep Habits Questionnaire (CSHQ), and children wore actigraphy watches while sleeping to objectively capture their sleep habits. The three groups were compared using ANCOVA, controlling for age effects. RESULTS: Children with FASD scored significantly higher than the other two groups on the CBCL subscales of attention problems, somatic complaints, social problems, delinquency, and aggressive behaviour, as well as the panic subscale of the SCAS. Children with FASD also scored higher on all measures of the BRIEF than the ASD and TD groups, indicating greater problems with working memory and more difficulty shifting between tasks, planning, organising, inhibiting their behaviour and exercising emotional control. Nocturnal sleep duration in children with FASD was reported as one hour less than TD children and 46 minutes less than children with ASD per night. CONCLUSIONS: The findings in this study highlight several syndrome specific features (shorter sleep duration, executive functioning difficulties, and higher levels of social and behavioural problems and panic) that potentially contribute to the unique phenotype of FASD. Whilst this research highlights the need for further work in this area, initial clinical screening for FASD should take such data on discernible characteristics, particularly the syndrome specificity of the BRIEF, into consideration.

FETAL ALCOHOL SPECTRUM DISORDERS (FASDS) IS A CONDITION THAT IS PROBABLY OFTEN MISSED. THIS SYNDROME IS BASED ON FEATURES IN FOUR DOMAINS: 1. REDUCED HEIGHT AND WEIGHT GROWTH, 2. SPECIFIC FACIAL FEATURES, 3. PREDISPOSED CENTRAL NERVOUS SYSTEM ABNORMALITIES (INCLUDING MICROCEPHALY) OR FUNCTION (NEUROLOGICAL, PSYCHOLOGICAL AND/OR BEHAVIORAL PROBLEMS) AND 4. (SUSPECTED) PRENATAL ALCOHOL USE BY THE MOTHER. DUE TO PSYCHIATRIC AND BEHAVIORAL PROBLEMS PATIENTS MAY ALSO BE SEEN IN SPECIALIZED MENTAL HEALTH CARE. TO INCREASE THE CHANCE THAT THESE PATIENTS WILL RECEIVE AN APPROPRIATE AND EFFECTIVE TREATMENT, AWARENESS OF THIS SYNDROME IS ESSENTIAL. WE DESCRIBE THE CLINICAL PICTURE ON THE BASIS OF A CASE DESCRIPTION, PROVIDE RECENT LITERATURE AND FORMULATE RECOMMENDATIONS FOR CLINICAL PRACTICE.

INTRODUCTION: Known protective factors for long-term outcome in children with fetal alcohol spectrum disorders (FASD) are early diagnosis and a stable, non-violent supportive environment. Which factors contribute to the stability of care is not yet known. Thus, the aim of our study was to evaluate whether the age at diagnosis and the complexity of brain dysfunction play a role for placement changes in children with FASD. MATERIALS AND METHODS: An online survey was conducted among caregivers and professionals caring for children with FASD and seeking help at the German FASD Competence Centre Bavaria (N = 232). The survey collected information about diagnosis, brain dysfunctions, behavioural factors influencing everyday life and changes of placement. The association of timing of diagnosis, brain dysfunctions and neurobehavioral impairment with changes of placement (<2 vs. 2 or more changes) was evaluated via logistic regression models. RESULTS: About 50% of the children received their diagnosis of FASD after the age of 5 years. The complexity of brain dysfunctions in children with FASD affecting everyday life was high. 15% of the children experienced four or more changes of placement. Children with more neuropsychological impairments experienced more changes of placement (OR: 2.53, 95% CI: 1.36-4.71). CONCLUSIONS: Even though our results need to be interpreted with caution due to methodological limitations such as the use of a convenience sample and limited statistical power, they imply that severely affected children with FASD experience a less stable environment. These children may therefore be at high risk for a negative prognosis. To warrant a better prognosis for the affected children, professionals urgently need to pay attention to early recognition and the complexity of neuropsychological impairments in children with FASD as well as to the support that caregivers urgently need.

BACKGROUND: Consideration of sex- and gender-related factors is critical for understanding and supporting health and wellbeing. Although both sex and gender influence people with developmental disabilities, there is relatively little research on these factors and their influences among individuals with fetal alcohol spectrum disorder (FASD), a complex neurodevelopmental disability impacting an estimated 4%-5% of the population. Understanding sex- and gender-related differences in FASD is needed to facilitate evidence-informed assessment, treatment planning, and advocacy. To begin unpacking these factors, we investigated sex-based differences in clinical presentation and experiences among individuals assessed for FASD across the lifespan. METHODS: We analyzed 2574 clinical records from 29 FASD diagnostic centers in Canada. Participants ranged in age from 1 to 61 years (mean 15.2 years), and more than half (58.3%) were male at birth. Study variables included participant demographics, physical indicators of prenatal alcohol exposure (PAE), neurodevelopmental impairment, FASD diagnosis, co-occurring physical and mental health diagnoses, and environmental adversity. RESULTS: There were no significant differences between males and females with respect to FASD diagnostic outcome or physical indicators of PAE. However, males experienced significantly more neurodevelopmental impairment. Females experienced higher rates of endocrine problems, anxiety, and depressive/mood disorders, whereas males had higher rates of attention deficit-hyperactivity disorder, conduct disorder, and oppositional defiant disorder. Adversity also differed by sex, with females experiencing higher rates of trauma and legal problems with victimization/custody, and males having more difficulties with school and offending/incarceration. Sex-based differences were most apparent in adolescents (13-17 years) and adults (≥25 years). CONCLUSIONS: Individuals with PAE/FASD experience notable sex-related differences in clinical presentation and experiences across the lifespan. Findings from this study should help to guide researchers, service providers, and policy makers to improve FASD screening, diagnosis, and intervention and better address the needs of individuals with PAE/FASD of all genders.

BACKGROUND: Fetal alcohol spectrum disorder (FASD) is a complex neurodevelopmental disorder that may arise following prenatal exposure to alcohol. Children with FASD tend to experience a diverse set of physical, social, cognitive, and behavioral symptoms. Caregivers of these children likely experience elevated levels of parenting stress; however, research in this area is still in its infancy. AIM: The present study sought to more fully understand the current state of the literature on parenting stress experienced by caregivers of children with FASD. METHOD: Databases including PsycInfo, Scopus, PsycArticles, and Google Scholar were searched for records meeting our inclusion criteria. RESULTS AND CONCLUSION: 15 studies were deemed eligible for this review. This literature suggests that caregivers of children with FASD experience heightened levels of parenting stress. Child factors, especially child behavior and executive functioning difficulties are associated with Child Domain stress, while parent factors are associated with Parent Domain stress. Gaps were identified in child and caregiver mental health issues, as well as placement information.

BACKGROUND: Executive dysfunction, especially impaired inhibitory control, is a common finding in individuals with fetal alcohol syndrome (FAS). Previous research has mostly focused on neural correlates of inhibitory deficits in children and adolescents. We investigated inhibitory functions and underlying cerebral activation patterns in young adult women with FAS. METHODS: Task performance and functional magnetic resonance imaging (fMRI) data were acquired during a Go/NoGo (GNG) inhibition task in 19 young adult women with FAS and 19 healthy female control subjects. Whole-brain activation and task performance analyses were supplemented by region of interest (ROI) analyses of fMRI data within a predefined cognitive control network (CCN). RESULTS: Task performance did not differ significantly between groups on errors of commission, associated with inhibitory control. Similarly, overall activation within the preselected ROIs did not differ significantly between groups for the main inhibitory contrast NoGo > Go. However, whole-brain analyses revealed activation differences in the FAS group when compared to controls under inhibitory conditions. This included hyperactivations in the left inferior frontal, superior temporal, and supramarginal gyri in the FAS group. Likewise, lateralization tendencies toward right-hemispheric ROIs were weaker in FAS subjects. In contrast to comparable inhibitory performance, attention-related errors of omission were significantly higher in the FAS group. Correspondingly, FAS subjects had lower activity in attention-related temporal and parietal areas. CONCLUSIONS: The known alterations of inhibitory functions associated with prenatal alcohol exposure in children and adolescents were not seen in this adult sample. However, differential brain activity was observed, reflecting potential compensatory mechanisms. Secondary results suggest that there is impaired attentional control in young adult women with FAS.

Background: Fetal Alcohol Spectrum Disorder (FASD) is a neurodevelopmental disorder characterized by cognitive and adaptive impairment. FASF can be presented or not with sentinel facial features (SFF). The presence of such SFF have been positively correlated with cognitive impairment in children with FASD.Objectives: The current study explores difference in global intellectual functioning and how cognition affects adaptive behavior in children with and without SFF.Methods: A total of 88 children and adolescents (55 males, 33 females) with confirmed FASD diagnosis were included in the study, of which 16 had sentinel facial features. Childrens' neuropsychological functioning was assessed using the Wechsler Intelligence Scale for Children (WISC-V) and The Behavioral Assessment of the Dysexecutive Syndromes for Children (BADS-C). Adaptive behavior was explored through the Adaptive Behavior Assessment System (ABAS-3).Results: Children with SFF performed more poorly in tasks assessing processing speed (t = 2.495, t = .020) and executive functioning (t = 4.147, t = .001). Those children also had lower IQ scores than children without SFF (t = 2.658, t = .016). BADS-C overall scaled score was related to three of the four domains of the ABAS scale (conceptual, social, and practical) but only in the group of FASD children without SFF (B = 0.547, t = .020; B = 0.544,t = .049; B = 0.431,t = .040, respectively).Conclusions: The present study founds poorer cognitive outcomes in children who have FASD with sentinel facial features. In children without SFF, stronger executive functioning is also related to significantly stronger reported conceptual, social, and practical adaptive behaviors. Better understanding of cognitive and adaptive functioning in children with FASD may help in the design of tailored evidenced-based interventions.

BACKGROUND: The ability to identify and interpret facial emotions plays a critical role in effective social functioning, which may be impaired in individuals with fetal alcohol spectrum disorders (FASD). We previously reported deficits in children with fetal alcohol syndrome (FAS) and partial FAS (PFAS) on the "Reading the Mind in the Eyes" (RME) test, which assesses the interpretation of facial emotion. This follow-up study in adolescents was designed to determine whether this impairment persists or represents a developmental delay; to classify the RME stimuli by valence (positive, negative, or neutral) and determine whether RME deficits differ by affective valence; and to explore how components of executive function mediate these associations. METHODS: The RME stimuli were rated and grouped according to valence. Sixty-two participants who had been administered the RME in late childhood (mean ± SD = 11.0 ± 0.4 years) were re-administered this test during adolescence (17.2 ± 0.6 years). Overall and valence-specific RME accuracy was examined in relation to prenatal alcohol exposure (PAE) and FASD diagnosis. RESULTS: Children with FAS (n = 8) and PFAS (n = 15) performed more poorly on the RME than non-syndromal heavily exposed (HE; n = 19) and control individuals (n = 20). By adolescence, the PFAS group performed similarly to HE and controls, whereas the FAS group continued to perform more poorly. No deficits were seen for positively valenced items in any of the groups. For negative and neutral items, in late childhood individuals with FAS and PFAS performed more poorly than HE and controls, but by adolescence only the FAS group continued to perform more poorly. Test-retest reliability was moderate across the two ages. At both timepoints, the effects in the FAS group were partially mediated by Verbal Fluency but not by other aspects of executive function. CONCLUSIONS: Individuals with full FAS have greater difficulty interpreting facial emotions than those with non-syndromal HE and healthy controls in both childhood and adolescence. By contrast, RME deficits in individuals with PFAS in childhood represent developmental delay.

BACKGROUND: Individuals with fetal alcohol spectrum disorders may exhibit a distinct pattern of dysmorphic facial features, growth restriction, and cognitive deficits, particularly in arithmetic. Magnitude comparison, a fundamental element of numerical cognition, is modulated by the numerical distance effect, with numbers closer in value more difficult to compare than those further apart, and by the automaticity of the association of numerical values with their symbolic representations (Arabic numerals). METHODS: We examined event-related potentials acquired during the Numerical Stroop numerical and physical tasks administered to 24 alcohol-exposed adolescents (eight fetal alcohol syndrome (FAS), eight partial FAS (PFAS), eight heavily exposed (HE) nonsyndromal) and 23 typically developing (TD), same- age controls. The distance effect was assessed on the numerical task to examine differences in reaction time (RT) and accuracy when two numbers are close in value (e.g., 1 vs. 2) compared to when the numbers are less close (e.g., 1 vs. 6). Automaticity was assessed in the physical task by examining the degree to which RT and accuracy are reduced when the relative physical size of two numerals is incongruent with their numerical values (e.g., 1 vs. 6). RESULTS: Adolescents in all four groups performed behaviorally as expected on these relatively simple magnitude comparison tasks, but accuracy was poorer and RT was slower on both tasks in the FAS and PFAS than the HE and TD groups. At the neurophysiological level, in the numerical task, a higher level of prenatal alcohol exposure was associated with smaller P2p amplitude. In the physical task, only the TD and nonsyndromal HE groups exhibited the expected smaller P300 amplitude in the incongruent than the congruent condition. CONCLUSIONS: These findings suggest that magnitude comparison in alcohol-exposed individuals may be mediated by recruitment of alternative neural pathways that are likely to be inefficient when number processing becomes more challenging.

Fetal alcohol spectrum disorder (FASD) is common and represents a significant public health burden, yet very few interventions have been tested in FASD. Cognitive deficits are core features of FASD, ranging from broad intellectual impairment to selective problems in attention, executive functioning, memory, visual-perceptual/motor skills, social cognition, and academics. One potential intervention for the cognitive impairments associated with FASD is the essential nutrient choline, which is known to have numerous direct effects on brain and cognition in both typical and atypical development. We provide a summary of the literature supporting the use of choline as a neurodevelopmental intervention in those affected by prenatal alcohol. We first discuss how alcohol interferes with normal brain development. We then provide a comprehensive overview of the nutrient choline and discuss its role in typical brain development and its application in the optimization of brain development following early insult. Next, we review the preclinical literature that provides evidence of choline's potential as an intervention following alcohol exposure. Then, we review a handful of existing human studies of choline supplementation in FASD. Lastly, we conclude with a review of practical considerations in choline supplementation, including dose, formulation, and feasibility in children.

BACKGROUND: Although the effects of prenatal alcohol exposure (PAE) have been studied extensively, there is relatively little information available on adult mental health functioning among exposed individuals. The current study compares the self-reported midlife mental health status of individuals who were prenatally exposed to alcohol and diagnosed in childhood with the effects of this exposure with that of unexposed individuals. METHODS: Participants (N = 292) were recruited from two longitudinal cohorts in Atlanta and Seattle and asked to complete an Adult Health Questionnaire that surveyed their current health and mental health status. The questionnaire was completed either in-person or remotely and included questions about current symptoms of depression and anxiety and mental health disorder diagnoses. The analysis compared a Nonexposed Contrast group to those in two exposure groups: (1) Alcohol Exposed with Fetal Alcohol Effect but not meeting criteria for Fetal Alcohol Syndrome (FAS) and (2) Alcohol Affected and meeting criteria for FAS. RESULTS: Both alcohol-exposed groups reported higher levels of current depressive symptoms and a higher prevalence of diagnoses of depression, anxiety, bipolar disorder, and/or attention deficit/hyperactivity disorder. No differences were noted for psychotic disorders. PAE was also associated with greater environmental stressors, including higher levels of adverse childhood events and lower current socioeconomic status. Path analyses suggested that PAE was indirectly related to mood disorders with its effects being mediated by other environmental factors. CONCLUSIONS: PAE is associated with greater rates of mental health disorders in middle adulthood. These outcomes appear to result from multiple stressors that affect individuals made vulnerable by their early alcohol exposure. Clinical outcomes could be improved by prevention efforts directed at preventing prenatal alcohol use and reducing environmental stressors later in life, and by the early identification of PAE and its effects.

Fetal Alcohol Spectrum Disorder (FASD) is characterized by a variety of morphological, behavioural and cognitive deficits, ranging from mild to severe. Numerous animal models, including the zebrafish, have been employed to better understand the onset, expression and progression of this disorder. Embryonic ethanol-induced deficits in learning and memory, anxiety, social responses and elevated alcohol self-administration have been successfully demonstrated in zebrafish. Studies in zebrafish have also shown the expression of these behavioural deficits depends upon the developmental stage of ethanol exposure, the age of observation, as well as the genotype (strain or population origin) of the tested zebrafish. Here, we investigate how the genotype and age of observation may influence embryonic ethanol-induced alterations in anxiety-like responses in zebrafish. Zebrafish embryos exposed to either 0% or 1% (vol/vol) ethanol at 24hpf were tested in an open tank at one of three stages: larval (6-8 days post fertilization (dpf)), mid-larval (16-18dpf), or juvenile (26-28dpf). Two genotypes were tested in this manner, ABNS (a quasi-inbred strain) and ABSK (a mix of AB, TU and TL strains). We found embryonic ethanol induced behavioural changes to significantly differ depending on the genotype and age of observation. For example, significant differences between control and ethanol exposed zebrafish in both genotypes were observed in juvenile zebrafish, but few significant treatment effects were observed in larval zebrafish. Additionally, ethanol appeared to alter anxiety-like behaviours in the ABNS genotype but did not have as robust of an effect on the ABSK genotype. Lastly, there were significant behavioural differences between unexposed (control) zebrafish of the two genotypes, suggesting baseline behavioural differences despite a common AB genetic origin.

BACKGROUND: Prenatal alcohol exposure (PAE) has been associated with compromised interhemispheric transfer of tactile stimuli in childhood and structural changes to the corpus callosum (CC). In this study, we used a finger localization task (FLT) to investigate whether interhemispheric transfer deficits persist in adolescence; whether effects of PAE on perceptual reasoning, working memory, and executive function are mediated by deficits in interhemispheric transfer of information; and whether CC size in childhood predicts FLT performance in adolescence. METHODS: Participants, aged 16 to 17 years, were from the Cape Town Longitudinal Cohort, whose mothers were recruited during pregnancy and interviewed regarding their alcohol use using the timeline follow-back method. Diagnoses of fetal alcohol syndrome (FAS) and partial FAS (PFAS) were determined by two expert dysmorphologists; nonsyndromal exposed children were designated as heavily exposed (HE); those born to abstainers or light drinkers, as controls. The FLT was administered to 74 participants (12 FAS, 16 PFAS, 14 HE and 32 controls). CC size at age 9 to 12 years was available for 35 participants (7 FAS, 13 PFAS, 5 HE and 10 control). RESULTS: Although the degree of PAE was similar in the FAS, PFAS, and HE groups, only the adolescents with FAS showed more transfer-related errors than controls in conditions in which one finger was stimulated. FLT performance mediated the effects of FAS on perceptual reasoning and executive function. In the subsample for which neuroimaging data from childhood were available, there was an association among adolescents with PAE of smaller CC volumes with more transfer-related errors on the one-finger/hand hidden condition, suggesting that CC damage previously seen in childhood continues to impact function through adolescence. CONCLUSIONS: This study provides evidence of compromised interhemispheric transfer of information in adolescents with FAS, while those with PFAS or heavy exposed nonsyndromal individuals are apparently spared. It is the first to show that PAE effects on important aspects of cognitive function are partially mediated by deficits in the interhemispheric transfer of information.

Children with fetal alcohol spectrum disorders (FASD) are known to experience cognitive and neurobehavioral difficulties, including in areas of executive function and social skills development. Interventions for these challenges have focused on a number of areas, including parent-based training. Despite the general consensus that specific parenting styles consistent with an "authoritative" - warm but firm - parenting approach may influence behavioral self-regulation, it is not known what specific parental interaction styles are associated with child engagement and emerging executive function in this population. The current study used an observation-based behavioral coding scheme during parent-child play interactions and associated parent report-based executive function measures in children with FASD. Here, we demonstrate that parental interaction styles with increased responsive/child-oriented behavior and parental affect are associated with higher levels of child play engagement, while parental interaction that has increased achievement-orientation is associated with higher levels of emerging executive function in children with FASD. These findings help inform future studies on behavioral targets in parent-based training programs and highlight the importance of considering certain parental interaction styles during parent-child play.

Children with prenatal alcohol exposure (PAE) often suffer from cognitive and neurobehavioral dysfunction throughout their lives, which may rise to a level of concern such that children receive a diagnosis under the fetal alcohol spectrum disorders (FASD) umbrella. Magnetoencephalography (MEG) contributes direct insight into neural processing and functional connectivity measures with temporal precision to understand cortical processing disorders that manifest during development. The impairment of perception may become more consequential among school-aged children with an FASD in the process of intellectual functioning and behavioral maturation. Fifty participants with the age range of 8-13 years participated in our study following parental informed consent and child assent. For each participant, visual responses were recorded using magnetoencephalography (MEG) while performing a prosaccade task with central stimuli (fovea centralis) and peripheral stimuli (left and right of central) presented on a screen, requiring participants to shift their gaze to the stimuli. After source analysis using minimum norm estimation (MNE), we investigated visual responses from each participant by measuring the latency and amplitude of visual evoked fields. Delayed peak latency of the visual response was identified in the primary visual area (calcarine fissure) and visual association areas (v2, v3) in young children with an FASD for both stimulus types (central and peripheral). But the difference in visual response latency was only statistically significant (p ≤ 0.01) for the peripheral (right) stimulus. We also observed reduced amplitude (p ≤ 0.006) of visual evoked response in children with an FASD for the central stimulus type in both primary and visual association areas. Multiple visual areas show impairment in children with an FASD, with visual delay and conduction disturbance more prominent in response to peripheral stimuli. Children with an FASD also exhibit significantly reduced amplitude of neural activation to central stimuli. These sensory deficits may lead to slow cognitive processing speed through continued intra-cortical network disturbance in children with an FASD.
