J Affect Disord 2024; 358:163-174. [PMID: 38718944 DOI: 10.1016/j.jad.2024.05.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2024] [Revised: 05/03/2024] [Accepted: 05/04/2024] [Indexed: 05/12/2024]
Abstract
BACKGROUND Individuals with prenatal alcohol exposure (PAE) commonly experience co-occurring diagnoses, which are often overlooked and misdiagnosed and have detrimental impacts on accessing appropriate services. The prevalence of these co-occurring diagnoses varies widely in the existing literature and has not been examined in PAE without an FASD diagnosis. METHOD A search was conducted in five databases and the reference sections of three review papers, finding a total of 2180 studies. 57 studies were included in the final analysis with a cumulative sample size of 29,644. Bayesian modeling was used to determine aggregate prevalence rates of co-occurring disorders and analyze potential moderators. RESULTS 82 % of people with PAE had a co-occurring diagnosis. All disorders had a higher prevalence in individuals with PAE than the general population with attention deficit hyperactivity disorder, learning disorder, and intellectual disability (ID) being the most prevalent. Age, diagnostic status, and sex moderated the prevalence of multiple disorders. LIMITATIONS While prevalence of disorders is crucial information, it does not provide a direct representation of daily functioning and available supports. Results should be interpreted in collaboration with more individualized research to provide the most comprehensive representation of the experience of individuals with PAE. CONCLUSIONS Co-occurring diagnoses are extremely prevalent in people with PAE, with older individuals, females, and those diagnosed with FASD being most at risk for having a co-occurring disorder. These findings provide a more rigorous examination of the challenges faced by individuals with PAE than has existed in the literature, providing clinicians with information to ensure early identification and effective treatment of concerns to prevent lifelong challenges.

Abstract
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.

Abstract
BACKGROUND Fetal alcohol syndrome (FAS) can result in cognitive dysfunction. Cognitive functions affected are subserved by few functional brain networks. Functional connectivity (FC) in these networks can be assessed with resting-state functional MRI (rs-fMRI). Alterations of FC have been reported in children and adolescents prenatally exposed to alcohol. Previous reports varied substantially regarding the exact nature of findings. The purpose of this study was to assess FC of cognition-related networks in young adults with FAS. METHODS Cross-sectional rs-fMRI study in participants with FAS (n = 39, age: 20.9 ± 3.4 years) and healthy participants without prenatal alcohol exposure (n = 44, age: 22.2 ± 3.4 years). FC was calculated as correlation between cortical regions in ten cognition-related sub-networks. Subsequent modelling of overall FC was based on linear models comparing FC between FAS and controls. Results were subjected to a hierarchical statistical testing approach, first determining whether there is any alteration of FC in FAS in the full cognitive connectome, subsequently resolving these findings to the level of either FC within each network or between networks based on the Higher Criticism (HC) approach for detecting rare and weak effects in high-dimensional data. Finally, group differences in single connections were assessed using conventional multiple-comparison correction. In an additional exploratory analysis, dynamic FC states were assessed. RESULTS Comparing FAS participants with controls, we observed altered FC of cognition-related brain regions globally, within 7 out of 10 networks, and between networks employing the HC statistic. This was most obvious in attention-related network components. Findings also spanned across subcomponents of the fronto-parietal control and default mode networks. None of the single FC alterations within these networks yielded statistical significance in the conventional high-resolution analysis. The exploratory time-resolved FC analysis did not show significant group differences of dynamic FC states. CONCLUSIONS FC in cognition-related networks was altered in adults with FAS. Effects were widely distributed across networks, potentially reflecting the diversity of cognitive deficits in FAS. However, no altered single connections could be determined in the most detailed analysis level. Findings were pronounced in networks in line with attentional deficits previously reported.

Abstract
OBJECTIVE Language and communication are largely understudied among youth with fetal alcohol spectrum disorders (FASD). Findings have been mixed, and have generally focused on more severely affected (i.e., children with FAS alone) or younger children. This study aimed to elucidate the profiles of language (i.e., receptive, expressive, general language) and communication (i.e., functional, social) abilities in adolescents with FASD. METHOD Participants aged 12-17 years with (AE = 31) and without (CON = 29) prenatal alcohol exposure were included. Receptive and expressive language were measured by the Clinical Evaluation of Language Fundamentals - Fifth Edition (CELF-5). Parents or caregivers completed the Children's Communication Checklist - Second Edition as a subjective measure of general language skills. Functional communication was measured by the Student Functional Assessment of Verbal Reasoning and Executive Strategies and parents or caregivers completed the Social Skills Improvement System Rating Scales as a measure of social communication. Multivariate analysis of variance determined the overall profiles of language and communication and whether they differed between groups. RESULTS The AE group performed significantly lower than the CON group on receptive language and parent report of general language while groups did not significantly differ on expressive language. Groups did not significantly differ on functional communication while social communication was significantly lower in the AE group. CONCLUSIONS Results of this study provide important information regarding the overall profile of basic language abilities and higher-level communication skills of adolescents with FASD. Ultimately, improving communication skills of youth with FASD may translate to better overall functioning.

Abstract
Introduction Fetal alcohol spectrum disorders (FASD) are the leading preventable neurodevelopmental disorders and two hallmark symptoms of FASD are abnormal behavior, and cognitive and learning deficits. The severity of alcohol's teratogenic effects on the developing brain is influenced by genetics and sex. We previously identified recombinant inbred BXD mouse strains that show differential vulnerability to ethanol-induced cell death in the developing hippocampus, a brain region important in learning and memory. The present study aimed to test the hypothesis that strains with increased vulnerability to ethanol-induced cell death in the hippocampus have concomitant deficits in multiple hippocampal-related behaviors during adolescence. Methods The current study evaluated the effects of developmental ethanol exposure on adolescent behavior in two BXD strains that show high cell death (BXD48a, BXD100), two that show low cell death (BXD60, BXD71), and the two parental strains (C57BL/6 J (B6), DBA/2 J (D2)). On postnatal day 7, male and female neonatal pups were treated with ethanol (5.0 g/kg) or saline given in two equal doses 2 h apart. Adolescent behavior was assessed across multiple behavioral paradigms including the elevated plus maze, open field, Y-maze, and T-maze. Results Our results demonstrate that the effects of developmental ethanol exposure on adolescent behavioral responses are highly dependent on strain. The low cell death strains, BXD60 and BXD71, showed minimal effect of ethanol exposure on all behavioral measures but did present sex differences. The parental -B6 and D2-strains and high cell death strains, BXD48a and BXD100, showed ethanol-induced effects on activity-related or anxiety-like behaviors. Interestingly, the high cell death strains were the only strains that showed a significant effect of postnatal ethanol exposure on hippocampal-dependent spatial learning and memory behaviors. Discussion Overall, we identified effects of ethanol exposure, strain, and/or sex on multiple behavioral measures. Interestingly, the strains that showed the most effects of postnatal ethanol exposure on adolescent behavior were the BXD strains that show high ethanol-induced cell death in the neonatal hippocampus, consistent with our hypothesis. Additionally, we found evidence for interactions among strain and sex, demonstrating that these factors have a complex effect on alcohol responses and that both are important considerations.

Relationship Between Task-Based and Parent Report-Based Measures of Attention and Executive Function in Children with Fetal Alcohol Spectrum Disorders (FASD).

Abstract
A majority of children with fetal alcohol spectrum disorders (FASD) have demonstrated attention and executive function deficits as measured by both parent report measures and performance on tasks requiring sustained levels of attention. However, prior studies have consistently reported a lack of association between parental report-based and task-based performance measures. The current study investigated whether changes in performance over time within-task (i.e., first-half versus second-half) better correspond to parental reports of executive function and temperament in children with FASD. Greater differences in split-half performance during a continuous performance task were found to be associated with higher parent-reported levels of behavioral regulation and inhibitory control. These findings suggest that within-task performance differences may more accurately reflect individual differences in executive function and temperament as measured by parental report and help to further inform the way in which cognitive processes are measured in children with FASD.

Abstract
ADHD is one of the most prevalent neuropsychiatric disorders of childhood, but symptoms vary considerably between individuals. Therefore, different ADHD subtypes can be distinguished. Yet, it is widely elusive whether the specific subtype is critical to consider when examining treatment effects. Based on theoretical considerations, this could be the case for EEG theta/beta neurofeedback. We examine the effects of such an intervention on rapid response execution and inhibition processes using a Go/Nogo task in the inattentive (ADD) and the combined (ADHD-C) subtype. We show that a single neurofeedback protocol affects opposing deficits depending on the ADHD subtype - namely the execution (in ADD) and inhibition of action (in ADHD-C). No changes occurred in the healthy controls. These findings are discussed in relation to overarching principles of neural oscillations, particularly in the beta frequency band. The data suggest that theta/beta neurofeedback trains a superordinate system strongly related to the function of neural beta frequency oscillations to tune neural networks important for the sampling of sensory information used for behavioral control.

Abstract
Objective: Fetal alcohol spectrum disorders (FASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) are associated with a range of neurocognitive impairments. Executive functioning deficits are a hallmark feature of both disorders. Method: The present meta-analysis was undertaken to disentangle the behavioral phenotype of FASD and ADHD by quantitatively differentiating executive functioning differences between these two groups. The current meta-analysis reviews 15 studies comparing children and adolescents with FASD and ADHD to typically developing (TD) samples, on a variety of executive function measures. Results: Results indicate that when compared with TD samples, FASD and ADHD samples demonstrate significant executive function deficits (d = 0.82 and d = 0.55, respectively). In addition, FASD samples experience significantly greater deficits when compared with ADHD samples (d = 0.25). Results were moderated by IQ and socioeconomic status. Conclusion: These findings further our understanding of the cognitive differences between FASD and ADHD samples and have the potential to influence future basic research, assessment, and intervention.

Abstract
Cannabis is the most commonly used illicit drug among pregnant women. Moreover, over half of pregnant women who are consuming cannabis are also consuming alcohol; however, the consequences of combined prenatal alcohol and cannabis exposure on fetal development are not well understood. The current study examined behavioral development following exposure to ethanol (EtOH) and/or CP-55,940 (CP), a cannabinoid receptor agonist. From postnatal days (PD) 4-9, a period of brain development equivalent to the third trimester, Sprague-Dawley rats received EtOH (5.25 g/kg/day) or sham intubation, as well as CP (0.4 mg/kg/day) or vehicle. All subjects were tested on open field activity (PD 18-21), elevated plus maze (PD 25), and spatial learning (PD 40-46) tasks. Both EtOH and CP increased locomotor activity in the open field, and the combination produced more severe overactivity than either exposure alone. Similarly, increases in thigmotaxis in the Morris water maze were caused by either EtOH or CP alone, and were more severe with combined exposure, although only EtOH impaired spatial learning. Finally, developmental CP significantly increased time spent in the open arms on the elevated plus maze. Overall, these data indicate that EtOH and CP produce some independent effects on behavior, and that the combination produces more severe overactivity in the open field. Importantly, these data suggest that prenatal cannabis disrupts development and combined prenatal exposure to alcohol and cannabis may be particularly damaging to the developing fetus, which has implications for the lives of affected individuals and families and also for establishing public health policy.

Abstract
Diagnostic assessment in Fetal Alcohol Spectrum Disorder (FASD) is informed by multidisciplinary assessment incorporating objective (i.e., test measures) and subjective means, such as parent and teacher behavior ratings. The purpose of this study was to extend our previous neuropsychological test findings by identifying parent and teacher ratings of academic achievement, attention, executive functioning, and adaptive functioning as predictors of an FASD diagnosis. The charts of 315 children and adolescents with prenatal alcohol exposure (PAE) who underwent assessment for FASD were retrospectively reviewed. Direct logistic regressions analyzed the contribution of different ratings on the likelihood of an FASD diagnosis. The results suggest that a number of rating measures do contribute toward accurately differentiating those with FASD from within a PAE population, including teacher ratings of learning problems, inattention, and adaptive skills. The classification accuracy for each regression was clinically significant (59.1-70.8%). Children with worse ratings on these variables are approximately 1.5 to 2 times more likely to receive an FASD diagnosis. Only teacher ratings (not parent) significantly contributed to whether a diagnosis was made, suggesting that teacher observational rating scales are a critical component of an FASD assessment. Together with our previous research examining neuropsychological evaluation and FASD diagnostic assessment, this study helps to further guide decisions to streamline care in multidisciplinary assessment and intervention planning.

Abstract
Growing evidence suggests that early symptoms of inattentiveness may affect the language development and academic success of young children. In the present study, we examined the extent to which profiles of inattentiveness and language could be discerned within a heterogeneous group of preschoolers attending early childhood special education programs (n = 461). Based on parent-reported observations of children's symptoms of inattentiveness and direct assessments of children's language skills (grammar, vocabulary, and narrative ability), three distinct profiles were identified. The three groups, representing levels of severity (at risk, almost average, above average), differed not only by their end of year performance, but also with respect to which their abilities changed over the course of the academic year. Children in the poorest performing profile had poorer mean scores in the spring of their preschool year on all measures, but exhibited patterns of gain that exceeded or equaled their peers in higher-performing groups, in the domains of vocabulary and grammar. Examination of subsequent kindergarten reading skills suggested that profile differences remained consistent. Findings underscore the associations between early symptoms of inattentiveness and language difficulties, and further indicate that these relations extend to the acquisition of early reading skills. Future research is needed to corroborate these findings with more robust measures of attention, and to understand the long-term associations between inattentiveness, language and literacy, and potential effects on these associations from early intervention.

Abstract
Prenatal alcohol exposure (PAE) is associated with a constellation of physical, neurocognitive, and behavioral abnormalities in offspring. The presence of internalizing (e.g., anxiety, mood disorders) and externalizing (e.g., oppositional defiant and conduct disorders) behavior problems has devastating and often long-lasting impacts on children, adolescents, and their families. The present meta-analysis explored the strength of the association between PAE and behavior problems, as well as factors that increase or mitigate risk. The current meta-analysis included 65 studies comparing children and adolescents with PAE to non- or light-exposed controls and attention-deficit/hyperactivity disorder (ADHD) samples, on a variety of internalizing and externalizing behavior outcomes. Results indicated that individuals with PAE are at increased risk for internalizing (d = 0.71, medium effect) and externalizing (d = 0.90, large effect) problems compared to control samples. The occurrence of total behavior problems was similar to that seen in ADHD samples. The strength of the association between internalizing and externalizing behavior problems and PAE was significantly moderated by several distinct sample characteristics, such as sample age, socioeconomic status, severity of exposure, and type of behavior problem. These findings further our understanding of the behavior problems experienced by children and adolescents with PAE.

Acute alcohol exposure during neurulation: Behavioral and brain structural consequences in adolescent C57BL/6J mice. Behav Brain Res 2016; 311:70-80. [PMID: 27185739 DOI: 10.1016/j.bbr.2016.05.004] [Citation(s) in RCA: 26] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2016] [Revised: 04/28/2016] [Accepted: 05/02/2016] [Indexed: 12/14/2022]
Abstract
Prenatal alcohol exposure (PAE) can induce physical malformations and behavioral abnormalities that depend in part on thedevelopmental timing of alcohol exposure. The current studies employed a mouse FASD model to characterize the long-term behavioral and brain structural consequences of a binge-like alcohol exposure during neurulation; a first-trimester stage when women are typically unaware that they are pregnant. Time-mated C57BL/6J female mice were administered two alcohol doses (2.8g/kg, four hours apart) or vehicle starting at gestational day 8.0. Male and female adolescent offspring (postnatal day 28-45) were then examined for motor activity (open field and elevated plus maze), coordination (rotarod), spatial learning and memory (Morris water maze), sensory motor gating (acoustic startle and prepulse inhibition), sociability (three-chambered social test), and nociceptive responses (hot plate). Regional brain volumes and shapes were determined using magnetic resonance imaging. In males, PAE increased activity on the elevated plus maze and reduced social novelty preference, while in females PAE increased exploratory behavior in the open field and transiently impaired rotarod performance. In both males and females, PAE modestly impaired Morris water maze performance and decreased the latency to respond on the hot plate. There were no brain volume differences; however, significant shape differences were found in the cerebellum, hypothalamus, striatum, and corpus callosum. These results demonstrate that alcohol exposure during neurulation can have functional consequences into adolescence, even in the absence of significant brain regional volumetric changes. However, PAE-induced regional shape changes provide evidence for persistent brain alterations and suggest alternative clinical diagnostic markers.

Abstract
Hyperactivity, or excess gross motor activity, is considered a core and ubiquitous characteristic of ADHD. Alternate models question this premise, and propose that hyperactive behavior reflects, to a large extent, purposeful behavior to cope with environmental demands that interact with underlying neurobiological vulnerabilities. The present review critically evaluates the ubiquity and environmental modifiability of hyperactivity in ADHD through meta-analysis of 63 studies of mechanically measured activity level in children, adolescents, and adults with ADHD relative to typically developing groups. Random effects models corrected for publication bias confirmed elevated gross motor activity in ADHD (d=0.86); surprisingly, neither participant age (child vs. adult) nor the proportion of each ADHD sample diagnosed with the inattentive subtype/presentation moderated this effect. In contrast, activity level assessed during high cognitive load conditions in general (d=1.14) and high executive functioning demands in particular (d=1.39) revealed significantly higher effect sizes than activity level during low cognitive load (d=0.36) and in-class schoolwork (d=0.50) settings. Low stimulation environments, more rigorous diagnostic practices, actigraph measurement of movement frequency and intensity, and ADHD samples that included fewer females were also associated with larger effects. Overall, the results are inconsistent with DSM-5 and ADHD models that a) describe hyperactivity as ubiquitous behavior, b) predict a developmental decline in hyperactivity, or c) differentiate subtypes/presentations according to perceived differences in hyperactive behavior. Instead, results suggest that the presence and magnitude of hyperactive behavior in ADHD may be influenced to a considerable extent by environmental factors in general, and cognitive/executive functioning demands in particular.

Abstract
BACKGROUND Children exposed to alcohol prenatally may suffer from behavioral and cognitive alterations that adversely affect their quality of life. Animal studies have shown that perinatal supplementation with the nutrient choline can attenuate ethanol's adverse effects on development; however, it is not clear how late in development choline can be administered and still effectively reduce the consequences of prenatal alcohol exposure. Using a rodent model, this study examined whether choline supplementation is effective in mitigating alcohol's teratogenic effects when administered during adolescence/young adulthood. METHODS Sprague-Dawley rats were exposed to alcohol (5.25 g/kg/d) during the third trimester equivalent brain growth spurt, which occurs from postnatal day (PD) 4 to 9, via oral intubation. Sham-intubated and nontreated controls were included. Subjects were treated with 100 mg/kg/d choline chloride or vehicle from PD 40 to 60, a period equivalent to young adulthood in the rat. After the choline treatment had ceased, subjects were tested on a series of behavioral tasks: open field activity (PD 61 to 64), Morris water maze spatial learning (PD 65 to 73), and spatial working memory (PD 87 to 91). RESULTS Ethanol-exposed subjects were overactive in the activity chambers and impaired on both the spatial and the working memory versions of the Morris water maze. Choline treatment failed to attenuate alcohol-related overactivity in the open field and deficits in Morris water maze performance. In contrast, choline supplementation significantly mitigated alcohol-related deficits in working memory, which may suggest that choline administration at this later developmental time affects functioning of the prefrontal cortex. CONCLUSIONS The results indicate that adolescent choline supplementation can attenuate some, but not all, of the behavioral deficits associated with early developmental alcohol exposure. The results of this study indicate that dietary intervention may reduce some fetal alcohol effects, even when administered later in life, findings with important implications for adolescents and young adults with fetal alcohol spectrum disorders.

Abstract
INTRODUCTION Our aim was to assess differences in movement measures in attention-deficit/hyperactivity disorder (ADHD) vs. typically developing (TD) controls. METHODS We performed meta-analyses of published studies on motion measures contrasting ADHD with controls. We also conducted a case-control study with children/adolescents (n = 61 TD, n = 62 ADHD) and adults (n = 30 TD, n = 19 ADHD) using the McLean motion activity test, semi-structured diagnostic interviews and the behavior rating inventory of executive function and Conners (parent, teacher; self) rating scales. RESULTS Meta-analyses revealed medium-to-large effect sizes for actigraph (standardized mean difference [SMD]: 0.64, 95% confidence interval (CI): 0.43, 0.85) and motion tracking systems (SDM: 0.92, 95% CI: 0.65, 1.20) measures in differentiating individuals with ADHD from controls. Effects sizes were similar in studies of children/adolescents ([SMD]: 0.75, 95% CI: 0.50, 1.01) and of adults ([SMD]: 0.73, 95% CI: 0.46, 1.00). In our sample, ADHD groups differed significantly in number of head movements (p = 0.02 in children; p = 0.002 in adults), displacement (p = 0.009/p < 0.001), head area (p = 0.03/p < 0.001), spatial complexity (p = 0.06/p = 0.02) and temporal scaling (p = 0.05/p = 0.04). Mean effect sizes were non-significantly larger (d = 0.83, 95% CI: 0.20, 1.45) in adults vs. children/adolescents with ADHD (d = 0.45, 95% CI: 0.08, 0.82). In the concurrent go/no-go task, reaction time variability was significantly greater in ADHD (p < 0.05 in both age groups) than controls. CONCLUSIONS Locomotor hyperactivity remains core to the construct of ADHD even in adults. Our results suggest that objective locomotion measures may be particularly useful in evaluating adults with possible ADHD.

Abstract
Attention deficits are often observed in children with prenatal alcohol exposure and attention-deficit/hyperactivity disorder (ADHD) is commonly diagnosed in this population. This study used an objective assessment tool to examine differences between alcohol-exposed and non-exposed children on core symptoms of ADHD: inattention, impulsivity, and hyperactivity. Two groups of individuals, aged 7-14years, participated in the study: alcohol-exposed children (AE, n=43), and non-exposed children (CON, n=54). Subjects were evaluated with the Quotient ADHD System, which provides objective data on ADHD core symptoms by combining an infrared motion tracking system and a computerized continuous performance task. Twelve separate ANCOVAs controlling for the effects of age and sex, were conducted on attention and motion variables. Results revealed that in comparison to the CON group, the AE group was significantly (p's<.05) less accurate, made an increased number of omission errors, had longer response latencies, and increased variability in response time. Moreover, the AE group spent less time staying still, and made an increased number of head movements, which traveled a larger distance, covered a greater area, and demonstrated a less complex movement pattern. No significant group differences were observed on the number of commission errors and temporal scaling. Our findings provide further support for the notion that inattention is a core deficit in children prenatally exposed to alcohol. Results from this study are also consistent with parent reports of increased hyperactivity. The Quotient ADHD System may be a useful objective measure of ADHD symptomatology in children with FASD.

Abstract
Prenatal alcohol exposure and attention-deficit/hyperactivity disorder (ADHD) result in behavioral issues related to poor executive function (EF). This overlap may hinder clinical identification of alcohol-exposed children. This study examined the relation between parent and neuropsychological measures of EF and whether parent ratings aid in differential diagnosis. Neuropsychological measures of EF, including the Delis-Kaplan Executive Function System (D-KEFS), were administered to four groups of children (8-16 years): alcohol-exposed with ADHD (AE+, n=80), alcohol-exposed without ADHD (AE-, n=36), non-exposed with ADHD (ADHD, n=93), and controls (CON, n=167). Primary caregivers completed the Behavior Rating Inventory of Executive Function (BRIEF). For parent ratings, multivariate analyses of variance revealed main effects of Exposure and ADHD and an interaction between these factors, with significant differences between all groups on nearly all BRIEF scales. For neuropsychological measures, results indicated main effects of Exposure and ADHD, but no interaction. Discriminant function analysis indicated the BRIEF accurately classifies groups. These findings confirm compounded behavioral, but not neuropsychological, effects in the AE+ group over the other clinical groups. Parent-report was not correlated with neuropsychological performance in the clinical groups and may provide unique information about neurobehavior. Parent-report measures are clinically useful in predicting alcohol exposure regardless of ADHD. Results contribute to a neurobehavioral profile of prenatal alcohol exposure.

Abstract
BACKGROUND Heavy prenatal alcohol exposure and attention-deficit/hyperactivity disorder (ADHD) are associated with adaptive behavior deficits. This study examined the interaction between these 2 factors on parent ratings of adaptive behavior. METHODS As part of a multisite study, primary caregivers of 317 children (8 to 16 years, M = 12.38) completed the Vineland Adaptive Behavior Scales-Second Edition (VABS-II). Four groups of subjects were included: children with prenatal alcohol exposure with ADHD (AE+, n = 82), children with prenatal alcohol exposure without ADHD (AE-, n = 34), children with ADHD (ADHD, n = 71), and control children (CON, n = 130). VABS-II domain scores (Communication, Daily Living Skills, Socialization) were examined using separate 2 (Alcohol Exposure [AE]) × 2 (ADHD diagnosis) between-subjects analyses of covariance. RESULTS There were significant main effects of AE (p < 0.001) and ADHD (p < 0.001) on all VABS-II domains; alcohol-exposed children had lower scores than children without prenatal alcohol exposure and children with ADHD had lower scores than those without ADHD. There was a significant AE × ADHD interaction effect for Communication, F(1, 308) = 7.49, p = 0.007, partial η(2) = 0.024, but not Daily Living Skills or Socialization domains (ps > 0.27). Follow-up analyses in the Communication domain indicated the effects of ADHD were stronger in comparison subjects (ADHD vs. CON) than exposed subjects (AE+ vs. AE-), and the effects of alcohol exposure were stronger in subjects without ADHD (AE- vs. CON) than in subjects with ADHD (AE+ vs. ADHD) CONCLUSION As found previously, both prenatal alcohol exposure and ADHD increase adaptive behavior deficits in all domains. However, these 2 factors interact to cause the greatest impairment in children with both prenatal alcohol exposure and ADHD for communication abilities. These results further demonstrate the deleterious effects of prenatal alcohol exposure and broaden our understanding of how ADHD exacerbates behavioral outcomes in this population.
