RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: This study aimed to develop an efficient and easily calculable risk score that can be used to identify an individual's risk of having been exposed to alcohol prenatally. METHODS: Data for this study were collected as part of the Collaborative Initiative on Fetal Alcohol Spectrum Disorders, Phases 2 and 3. Two cohorts (ages 5 to 17 years) completed a comprehensive neurobehavioral battery and a standard dysmorphology exam: a development cohort (DC; n = 325) and a comparative cohort (CC; n = 523). Both cohorts included two groups: those with histories of heavy prenatal alcohol exposure (AE-DC, n = 121; AE-CC, n = 177) and a control group that included subjects with minimal or no prenatal alcohol exposure (CON-DC, n = 204; CON-CC, n = 346). Behavioral assessments and physical exam data were combined using regression techniques to derive a risk score indicating the likelihood of prenatal alcohol exposure. Subjects were then divided into two subgroups: (1) low risk and (2) high risk. Chi-square (χ2 ) determined classification accuracy and ROC curves were produced to assess the predictive accuracy. Correlations between risk scores and intelligence quotient and executive function scores were calculated. RESULTS: Subjects were accurately classified in the DC (χ2  = 78.61, p < 0.001) and CC (χ2  = 86.63, p < 0.001). The classification model also performed well in the DC (ROC = 0.835 [SE = 0.024, p < 0.001]) and CC (ROC = 0.786 [SE = 0.021, p < 0.001]). In the AE-CC and CON-CC, there were modest but significant associations between the risk score and executive function (AE-CC: r = -0.20, p = 0.034; CON-CC: r = -0.28, p < 0.001) and intelligence quotient (AE-CC: r = -0.20, p = 0.034; CON-CC: r = -0.28, p < 0.001). CONCLUSION(S): The risk score significantly distinguished alcohol-exposed from control subjects and correlated with important cognitive outcomes. It has significant clinical potential and could be easily deployed in clinical settings.

RESUMO

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.

RESUMO

BACKGROUND: The initial confirmatory factor analysis of the Alcohol Related Neurodevelopmental Disorder Behavioral Checklist (ABC) utilized a population of 203 children. The analysis identified 10 independent measures (executive functioning, attention and concentration, cognition, memory, confabulation, gullibility, communication skills, academic skills, living/social skills, and juvenile justice). The 10 measures differentiated children with FASD from non-FASD controls. In this study, we present a validity study of the ABC using a different population of children with FASD and non-FASD controls. METHODS: A chart review identified 224 children with ABC checklist scores who had been evaluated for FASD. From this sample, we implemented a case-control study of 76 children diagnosed with FASD and 76 non-FASD controls who were matched by gender and closest age in years (mean age was 8.5 years). RESULTS: The averages of the total score and individual domain scores were compared between the 2 data sets and then between children with FASD and non-FASD controls. Children with FASD had significantly higher scores on all 10 measures than the non-FASD controls. There were very high sensitivity and specificity scores for the total score cutoff and for all 10 of the individual measures. CONCLUSIONS: In an independent sample, we found minimal differences between the previous data and the current validation study on measures of average total score cutoffs, scores for the 10 measures and correlations. Combining the 2 samples yielded robust differences in scores between children with FASD and non-FASD controls. The sensitivity, specificity and accuracy estimates were also very high. The ABC Screen appears to have acceptable epidemiologic performance data to support its use as a screening tool and as an initial step in differentiating children with FASD from those who do not have FASD.

RESUMO

BACKGROUND: In children with prenatal alcohol exposure, spatial working memory is affected and brain regions important for spatial working memory performance exhibit atypical neurodevelopment. We therefore hypothesized that children with prenatal alcohol exposure may also have atypical development of spatial working memory ability. METHODS: We examined the relation between spatial working memory and age using a cross-sectional developmental trajectory approach in youth with and without histories of heavy prenatal alcohol exposure. The Cambridge Neuropsychological Test Automated Battery Spatial Working Memory subtest was administered to children 5.0 to 16.9 years old. RESULTS: While the controls and children with prenatal alcohol exposure showed similar performance at younger ages, larger group differences were observed in older children. This effect was replicated in a separate sample. CONCLUSIONS: The atypical brain development that has previously been reported in children with heavy prenatal alcohol exposure may have clinically relevant implications for cognitive development; however, longitudinal cognitive analyses are needed.

RESUMO

BACKGROUND: Although deficits in the interpretation of affective facial expressions have been described clinically and in behavioral studies of fetal alcohol spectrum disorders (FASD), effects of prenatal alcohol exposure on the neural networks that mediate affective appraisal have not previously been examined. METHODS: We administered a nonverbal event-related fMRI affective appraisal paradigm to 64 children (mean age = 12.5 years; 18 with fetal alcohol syndrome (FAS) or partial FAS (PFAS), 18 nonsyndromal heavily exposed (HE), and 28 controls). Happy, sad, angry, fearful, and neutral faces and pixelated control images were presented sequentially in a randomized order. The child indicated whether the currently displayed face showed the same or different affect as the previous one. RESULTS: Data from whole-brain analyses showed that all groups activated the appropriate face processing neural networks. Region of interest analyses indicated that, compared to HE and control children, the FAS/PFAS group exhibited greater blood oxygenation level-dependent (BOLD) signal changes when processing neutral faces than pixelated images in 2 regions that form part of the visual sensory social brain network, which plays an important role in the initial processing of facial affect. By contrast, BOLD signal when processing angry faces was weaker for the FAS/PFAS group in a region involved in the processing of facial identity and facial expressions and in a region involved in the recognition and selection of behavioral responses to aggressive behavior. CONCLUSIONS: These findings of greater BOLD signal in the FAS/PFAS group in response to neutral faces suggest less efficient neural processing of more difficult to interpret emotions, and the weaker BOLD response to angry faces suggests altered processing of angry stimuli. Although behavioral performance did not differ in this relatively simple affective appraisal task, these data suggest that in children with FAS and PFAS, the appraisal of neutral affect and anger is likely to be more effortful in more challenging and dynamic social contexts.

RESUMO

BACKGROUND: Rating scales are designed to complement traditional performance-based measures, and both can provide useful information about the functioning of youth with histories of prenatal alcohol exposure. Few studies, however, have compared ratings from multiple informants or the relationship between these subjective rating scale scores and the objective results from laboratory performance-based scales. METHODS: The current study addressed both of these questions in 3 study groups: children with histories of prenatal alcohol exposure (n = 47), attention-deficit/hyperactivity disorder (ADHD; n = 41), and typically developing controls (CON; n = 73). All subjects completed a standardized neuropsychological test battery, including laboratory measures of executive functioning and a self-report measure of executive function behaviors. Parents and teachers completed corresponding rating scales of executive function behaviors for each subject. This study assessed the relationship between these behavior rating scales and corresponding neuropsychological tests, and interrater agreement among the multiple informants. RESULTS: Weak correlations were found between the rating scales and laboratory measures, indicating poor convergent validity for the behavior rating scale. Interrater reliability was found but it differed by group. Agreement was found between parent and teacher ratings for children with prenatal alcohol exposure, whereas teacher-child agreement was found for those with ADHD. CONCLUSIONS: Findings from this study indicate that behavior ratings can be used to supplement laboratory measures but may not be measuring cognitive abilities regardless of whether a clinical diagnosis is present. A multimethod approach should be used when measuring skills in this domain. This was one of the first studies to examine cross-informant agreement in a sample of children with prenatal alcohol exposure. Further research is necessary to understand why interrater agreement differed for children with prenatal alcohol exposure and those with ADHD.

RESUMO

BACKGROUND: Fetal alcohol spectrum disorder (FASD) is a significant public health problem that is associated with a broad range of physical, neurocognitive, and behavioral effects resulting from prenatal alcohol exposure (PAE). Magnetic resonance imaging (MRI) has been an important tool for advancing our knowledge of abnormal brain structure and function in individuals with FASD. However, whereas only a small number of studies have applied graph theory-based network analysis to resting-state functional MRI (fMRI) data in individuals with FASD additional research in this area is needed. METHODS: Resting-state fMRI data were collected from adolescent and young adult participants (ages 12-22) with fetal alcohol syndrome (FAS) or alcohol-related neurodevelopmental disorder (ARND) and neurotypically developing controls (CNTRL) from previous studies. Group independent components analysis (gICA) was applied to fMRI data to extract components representing functional brain networks. Functional network connectivity (FNC), measured by Pearson correlation of the average independent component (IC) time series, was analyzed under a graph theory framework to compare network modularity, the average clustering coefficient, characteristic path length, and global efficiency between groups. Cognitive intelligence, measured by the Wechsler Abbreviated Scale of Intelligence (WASI), was compared and correlated to global network measures. RESULTS: Group comparisons revealed significant differences in the average clustering coefficient, characteristic path length, and global efficiency. Modularity was not significantly different between groups. The FAS and ARND groups scored significantly lower than the CNTRL group on Full Scale IQ (FS-IQ) and the Vocabulary subtest, but not the Matrix Reasoning subtest. No significant associations between intelligence and graph theory measures were detected. CONCLUSION: Our results partially agree with previous studies examining global graph theory metrics in children and adolescents with FASD and suggest that the exposure to alcohol during prenatal development leads to disruptions in aspects of functional network segregation and integration.

RESUMO

Magnetic resonance imaging (MRI) studies of fetal alcohol spectrum disorder (FASD) have shown reductions of brain volume associated with prenatal exposure to alcohol. Previous studies consider regional brain volumes independently but ignore potential relationships across numerous structures. This study aims to (a) identify a multivariate model based on regional brain volume that discriminates children/adolescents with FASD versus healthy controls, and (b) determine if FASD classification performance can be increased by building classification models separately for each sex. Three-dimensional T1-weighted MRI from two independent childhood/adolescent datasets were used for training (79 FASD, aged 5.7-18.9 years, 35 males; 81 controls, aged 5.8-18.5 years, 32 males) and testing (67 FASD, aged 6.0-19.6 years, 38 males; 74 controls, aged 5.2-19.5 years, 42 males) a classification model. Using FreeSurfer, 87 regional brain volumes were extracted for each subject and were used as input into a support vector machine generating a classification model from the training data. The model performed moderately well on the test data with accuracy 77%, sensitivity 64%, and specificity 88%. Regions that contributed heavily to prediction in this model included temporal lobe and subcortical gray matter. Further investigation of two separate models for males and females showed slightly decreased accuracy compared to the model including all subjects (male accuracy 70%; female accuracy 67%), but had different regional contributions suggesting sex differences. This work demonstrates the potential of multivariate analysis of brain volumes for discriminating children/adolescents with FASD and provides indication of the most affected regions.

RESUMO

Individuals with fetal alcohol spectrum disorder (FASD) experience remarkably high rates of mental health and substance use challenges, beginning early in life and extending throughout adulthood. Proactive intervention can help to mitigate some of these negative experiences. Although the literature on FASD intervention is growing, there is currently a lack of consolidated evidence on interventions that may improve mental health and substance use outcomes in this population. Informed by a life course perspective, we undertook a systematic review of the literature to identify interventions that improve mental wellness through all developmental stages for people with prenatal alcohol exposure (PAE) and FASD. A total of 33 articles were identified, most of which were focused on building skills or strategies that underlie the well-being of children with PAE and FASD and their families. Other interventions were geared toward supporting child and family wellness and responding to risk or reducing harm. There was a notable lack of interventions that directly targeted mental health and substance use challenges, and a major gap was also noted in terms of interventions for adolescents and adults. Combined, these studies provide preliminary and emerging evidence for a range of intervention approaches that may support positive outcomes for individuals with FASD across the life course.

RESUMO

BACKGROUND: The effects of prenatal alcohol exposure (PAE) are conceptualized as fetal alcohol spectrum disorder, with fetal alcohol syndrome (FAS) as the most severe. Many find it more difficult to characterize behavioral and cognitive effects of exposure on the central nervous system when physical signs are not present. In the current study, an operational definition of alcohol-related neurodevelopmental disorder (ARND) was examined to determine its usefulness in discrimination of children classified as ARND based on behavior (ARND/B) and cognition (ARND/C) from children in 4 contrast groups: (i) children exposed to study-defined "risky drinking"; (ii) children with any reported PAE; (iii) children classified as "Higher Risk" for developmental problems; and (iv) children classified as "Lower Risk." METHODS: A total of 1,842 children seen as part of a surveillance study (J Am Med Assoc, 319, 2018, 474) were evaluated for alcohol exposure and physical characteristics of FAS, and completed neurodevelopmental testing. Ninety-one were identified as either ARND/B or ARND/C and contrasted with other groups to further identify distinguishing patterns. Multinomial logistic regression (MLR) was used to examine the accuracy of classification and to identify factors contributing to such classification. RESULTS: Children described as ARND/C were distinct from other groups based on cognition and behavior as well as demographic factors (e.g., age, race, SES), child characteristics (e.g., gestational age; sex), and other drug exposures, while those described as ARND/B differed only on behavior and other drug exposures. MLR models successfully discriminated ARND groups from children in other groups with accuracy ranging from 79% (Higher Risk) to 86.7% (Low Risk). CONCLUSIONS: ARND has been a subject of debate. This analysis suggests the effects of alcohol on behavior and cognition even in the absence of the characteristic facial features and growth deficiency that can be identified. The results also indicate that it may be possible to distinguish such children from those in other high-risk groups.

RESUMO

BACKGROUND: Fetal alcohol spectrum disorder (FASD) is a diagnosis relating to neurocognitive impairments associated with prenatal alcohol exposure. A key aspect of improving FASD diagnostic processes and management is understanding the demographic and neurocognitive profile of those living with FASD. The aim of this study was to describe the demographic and neurocognitive profile of the first 199 individuals diagnosed with FASD in PATCHES Paediatrics clinics. METHODS: A retrospective cross-sectional descriptive study design was conducted with individuals diagnosed with FASD between 2013 and 2018 through a multidisciplinary team according to the Australian FASD Diagnostic Guidelines. RESULTS: Participants were primarily male 133 (66.8%) and Aboriginal Australian 147 (73.9%), aged 2 to 31 (mean 10.5), with 94 (47.3%) from remote or very remote parts of Western Australia. Participants came from low 119 (59.8%), medium 48 (24.1%), and high 32 (16.1%) socioeconomic (SE) backgrounds. Low SE background was found to be a predictor of number of sentinel facial features (Wald χ2 (1) = 4.03, p < 0.05). Most received a diagnosis of FASD with <3 sentinel features 165 (82.9%). Participants either had 6 or more 46 (23.1%), 5 44 (22.1%), 4 55 (27.6%), or 3 (27.1%) neurodevelopmental domains impaired. Executive functioning was the most commonly impaired neurodevelopmental domain 158 (79.4%), and 31 (61%) reported sleep disturbance. ADHD was the most observed comorbid condition (41.7%). CONCLUSIONS: This study improves our current understanding of neurocognitive and demographic profiles in individuals with FASD that have been clinically referred for diagnosis within Western Australia and the Northern Territory, and highlights the importance of prevention and early assessment/diagnosis as well as guidance regarding more targeted interventions. FASD affects individuals from all cultural and SE backgrounds. Individuals from middle to higher SE groups are at risk of FASD with prevention efforts needing to target these sectors of society. Suggestions for future research directions are also provided.

RESUMO

OBJECTIVES: A number of commonly used performance validity tests (PVTs) may be prone to high failure rates when used for individuals with severe neurocognitive deficits. This study investigated the validity of 10 PVT scores in justice-involved adults with fetal alcohol spectrum disorder (FASD), a neurodevelopmental disability stemming from prenatal alcohol exposure and linked with severe neurocognitive deficits. METHOD: The sample comprised 80 justice-involved adults (ages 19-40) including 25 with confirmed or possible FASD and 55 where FASD was ruled out. Ten PVT scores were calculated, derived from Word Memory Test, Genuine Memory Impairment Profile, Advanced Clinical Solutions (Word Choice), the Wechsler Adult Intelligence Scale - Fourth Edition (Reliable Digit Span and age-corrected scaled scores (ACSS) from Digit Span, Coding, Symbol Search, Coding - Symbol Search, Vocabulary - Digit Span), and the Wechsler Memory Scale - Fourth Edition (Logical Memory II Recognition). RESULTS: Participants with diagnosed/possible FASD were more likely to fail any single PVT, and failed a greater number of PVTs overall, compared to those without FASD. They were also more likely to fail based on Word Memory Test, Digit Span ACSS, Coding ACSS, Symbol Search ACSS, and Logical Memory II Recognition, compared to controls (35-76%). Across both groups, substantially more participants with IQ <70 failed two or more PVTs (90%), compared to those with an IQ ≥70 (44%). CONCLUSIONS: Results highlight the need for additional research examining the use of PVTs in justice-involved populations with FASD.

RESUMO

In utero alcohol exposure can disrupt the development of the fetal brain and result in a wide range of neurobehavioral outcomes collectively known as fetal alcohol spectrum disorders (FASD). This paper provides a comprehensive review of the cognitive and behavioral outcomes of prenatal alcohol exposure, including domains of general intelligence, executive functioning, language development, learning and memory, adaptive functioning, academic performance, and concurrent psychopathology. In addition, the current status of the neurobehavioral profile of FASD and its potential as a diagnostic tool will be discussed.
