Higher functioning children with prenatal alcohol exposure: is there a specific neurocognitive profile?

Current and ideal living arrangements and supports for Canadian adults with fetal alcohol spectrum disorder (FASD)-Part I: Perspectives from adults with FASD

BACKGROUND

Adults with fetal alcohol spectrum disorder (FASD) can thrive with lifelong support in daily living activities. Previous research examining living support for adults with FASD has heavily relied on caregiver reports rather than lived experiences, which can undermine opportunities for self-determination. In this study, we examined the perspectives of adults with FASD to better understand: (1) the ways in which they are supported with daily life activities; and (2) their ideal future living arrangements and supports.

METHODS

This article presents findings from the perspective of adults with FASD as part of a broader project involving both adults with FASD and the caregivers who support them. Interviews were conducted with four Canadian adults with FASD who live in housing with supportive services and seven adults with FASD who live at home with the support of caregivers. Framework analyses, a structured approach to analyzing qualitative data, were used to examine participants' perspectives.

RESULTS

In addition to providing support for previous findings, participants provided novel information regarding: (1) their daily living supports; (2) positive and negative aspects of their arrangements; and (3) ideal living environments and supports.

CONCLUSIONS

This study offers insight into participants' perspectives regarding their living support, which is critical to inform housing and aid in self-determination. Areas of support outlined by participants can be used to begin conversations regarding the support required in housing arrangements for adults with FASD.

Current and ideal living arrangements and supports for Canadian adults with fetal alcohol spectrum disorder: Part II-Perspectives from caregivers

BACKGROUND

Caregivers supporting adults with fetal alcohol spectrum disorder (FASD) report concerns regarding living arrangements and services for their adult children with FASD. Best practices for living support for adults with FASD are under-researched, and few studies have explored the experiences of caregivers whose children are adults. This study examined the perspectives of caregivers who support adults (18+) with FASD regarding: (1) current ways adults with FASD are supported with daily life activities; and (2) ideal future living arrangements and supports.

METHODS

This article presents findings from the perspective of caregivers who support adults with FASD, as part of a broader project involving both adults with FASD and caregivers. Semi-structured interviews were conducted with 11 Canadian caregivers who live at home with an adult with FASD (aged 18+). Responses were examined using framework analysis, a structured approach to analyzing qualitative data.

RESULTS

Caregivers described their experiences and perspectives regarding: (1) current ways adults with FASD are supported in their daily activities; (2) strategies for successful support; (3) ideal future living arrangements and supports; and (4) concerns for the future. Notably, almost every participant raised pressing concerns regarding the future living arrangements for the person they support once they are no longer able to provide care.

CONCLUSIONS

This study explores caregivers' perspectives regarding living support needed by adults with FASD, which can inform support programs and housing services. Findings demonstrate an urgent need for policy change directed toward developing available, affordable, and appropriate housing for adults with FASD.

Latent classes of neurodevelopmental profiles and needs in children and adolescents with prenatal alcohol exposure

BACKGROUND

Fetal alcohol spectrum disorder (FASD) resulting from prenatal alcohol exposure (PAE) is a common neurodevelopmental disorder, but substantial interindividual heterogeneity complicates timely and accurate assessment, diagnosis, and intervention. The current study aimed to identify classes of children and adolescents with PAE assessed for FASD according to their pattern of significant neurodevelopmental functioning across 10 domains using latent class analysis (LCA), and to characterize these subgroups across clinical features.

METHODS

Data from the Canadian National FASD Database, a large ongoing repository of anonymized clinical data received from diagnostic clinics across Canada, was analyzed using a retrospective cross-sectional cohort design. The sample included 1440 children and adolescents ages 6 to 17 years (M = 11.0, SD = 3.5, 41.7% female) with confirmed PAE assessed for FASD between 2016 and 2020.

RESULTS

Results revealed an optimal four-class solution. The Global needs group was characterized by high overall neurodevelopmental impairment considered severe in nature. The Regulation and Cognitive needs groups presented with moderate but substantively distinguishable patterns of significant neurodevelopmental impairment. The Attention needs group was characterized by relatively low probabilities of significant neurodevelopmental impairment. Both the Global and Regulation needs groups also presented with the highest probabilities of clinical needs, further signifying potential substantive differences in assessment and intervention needs across classes.

CONCLUSIONS

Four relatively distinct subgroups were present in a large heterogeneous sample of children and adolescents with PAE assessed for FASD in Canada. These findings may inform clinical services by guiding clinicians to identify distinct service pathways for these subgroups, potentially increasing access to a more personalized treatment approach and improving outcomes.

Identification of Seminal Physical Features of Prenatal Alcohol Exposure by Child Psychologists

Introduction

Prenatal alcohol exposure (PAE) impacts an estimated 5% or more children born in the USA and is associated with life-long neuropsychological deficits. Early identification is essential but access to diagnostic evaluation is limited. This study reports on the effectiveness of training child psychologists to identify and measure the salient physical features of PAE.

Methods

Children, 8–13 years, were divided into two groups: (1) children meeting criteria for PAE (n = 46) and (2) typically developing controls without PAE (TD; n = 36). Child psychologists were trained to reliability measure height, weight, occipital frontal circumference (OFC), and the characteristic facial features of FASD independent of knowledge of PAE history.

Results

Groups differed significantly on meeting the diagnostic criteria proposed by Hoyme et al. (Pediatrics, 138:e20154256, 2016) on height, OFC, upper vermillion border, philtrum, and palpebral fissure length. They did not differ on weight. All children in the alcohol exposed group could be classified as meeting criteria for an FASD whereas none in the unexposed group met criteria.

Discussion

This study demonstrated that child psychologists, blind to PAE history, could be reliably trained to assess the physical features of children with PAE. Because early diagnosis and intervention is of paramount importance, we propose that inclusive diagnostic criteria for FASD and the use of psychologists and other allied health professionals, trained to screen for the diagnosis, should be expanded in clinical practice.

Impact of prenatal alcohol exposure on intracortical myelination and deep white matter in children with attention deficit hyperactivity disorder

White matter alterations have been reported in children with prenatal alcohol exposure (PAE) and in children with attention deficit hyperactivity disorder (ADHD); however, as children with PAE often present with ADHD, covert PAE may have contributed to previous ADHD findings. Additionally, data regarding intracortical myelination in ADHD are lacking. Therefore, we evaluated intracortical myelination (assessed as the T1w/T2w ratio at 4 cortical ribbon levels) and myelin-related deep white matter features in children (aged 8-13 years) with ADHD with PAE (ADHD + PAE), children with familial ADHD without PAE (ADHD-PAE), and typically developing (TD) children. In widespread tracts, ADHD + PAE children showed higher mean and radial diffusivity than TD and ADHD-PAE children and lower fractional anisotropy than ADHD-PAE children; ADHD-PAE and TD children did not differ significantly. Compared to TD children, ADHD + PAE children had lower intracortical myelination only at the deepest cortical level (mainly in right insula and cingulate cortices), while ADHD-PAE children had lower intracortical myelination at multiple cortical levels (mainly in right insula, sensorimotor, and cingulate cortices); ADHD + PAE and ADHD-PAE children did not differ significantly in intracortical myelination. Considering the two ADHD groups jointly (via non-parametric combination) revealed common reductions in intracortical myelination, but no common deep white matter abnormalities. These results suggest the importance of considering PAE in ADHD studies of white matter pathology. ADHD + PAE may be associated with deeper, white matter abnormalities, while familial ADHD without PAE may be associated with more superficial, cortical abnormalities. This may be relevant to the different treatment response observed in these two ADHD etiologies.

Unfitness to stand trial and fetal alcohol spectrum disorder: Understanding and responding to FASD within the criminal justice system in New Zealand

Fetal alcohol spectrum disorder (FASD) is an increasingly important issue in the New Zealand (NZ) Criminal Justice System (CJS). FASD may impact an offender's ability to participate meaningfully in the trial process, giving rise to the issue of unfitness to stand trial. Capacity to apprehend, comprehend, participate in, make decisions about and communicate within legal process intersect with the complexity and severity of charges. Courts are required to make a nuanced analysis of multiple and complex factors, merging medical and legal expertise into decisions made. We explore the nature of FASD and its implications for criminal justice in NZ. The legal and clinical issues in relation to fitness and FASD will be discussed.

Diminished culpability in fetal alcohol spectrum disorders (FASD)

There is a biological basis for diminished criminal responsibility in offenders with fetal alcohol spectrum disorders (FASD) just as there is in those with intellectual disability. Functional limitations affecting cognition in both neurodevelopmental conditions stem directly from structural brain damage at a gross and molecular level, which usually impairs executive functioning among other cognitive skills. Executive functioning, which includes reasoning and impulse control, is the only neural system in the brain that involves conscious thought. With respect to the law, impaired reasoning or rationality is an aspect of mens rea ("guilty mind"). When rationality is impaired by prenatal alcohol exposure, acts driven by strong emotion and urges can occur, which has obvious implications regarding criminal responsibility. The Atkins decision by the U.S. Supreme Court reflects the rationale that organically based brain dysfunction in executive skills reduces criminal culpability. We argue that people with FASD who have similar brain dysfunction likewise have reduced criminal responsibility.

A meta-analytic review of adaptive functioning in fetal alcohol spectrum disorders, and the effect of IQ, executive functioning, and age

INTRODUCTION

Fetal alcohol spectrum disorders (FASD) are highly prevalent developmental disabilities associated with prenatal alcohol exposure. In addition to varied strengths and unique talents, people with FASD experience significant challenges, including in adaptive functioning. Adaptive functioning refers to skills related to everyday life such as communication, practical skills, and social skills. For the current review, we aimed to understand how adaptive functioning in FASD compares to that of alcohol nonexposed individuals and those with attention deficit-hyperactivity disorder (ADHD). Additionally, we investigated how this relationship may change based on IQ, executive functioning, and age.

METHOD

The current review was registered in the International Prospective Register of Systematic Reviews. Studies were eligible for inclusion if they measured adaptive functioning and included an FASD group and at least one eligible comparison group. Articles available in May 2021 in PubMed, PsycInfo, Scopus, and ProQuest Dissertations were searched. Publication bias was assessed using Egger's regression and three-level random effects models were computed for all domains of adaptive functioning. Possible moderation by IQ, executive functioning, and age were investigated when heterogeneity analyses were significant. A post hoc moderation analysis of recruitment method was also completed.

RESULTS

Thirty studies were included. Individuals with FASD had significantly lower adaptive functioning than other groups, with effect sizes ranging from 1.04 to 1.35 compared to alcohol nonexposed groups and from 0.30 to 0.43 compared to ADHD groups. No significant moderating effects were found for IQ or age; executive functioning significantly moderated communication skills in FASD compared to the alcohol nonexposed group. Recruitment method significantly affected this relationship, with larger effect sizes on average found for clinically identified samples than at-risk or population samples.

CONCLUSIONS

Individuals with FASD have impairments in adaptive functioning relative to alcohol nonexposed and ADHD groups, regardless of IQ, executive functioning, or age. Limitations of the review include small sample sizes in some comparisons and a limited age range.

Cortical gyrification in children with attention deficit-hyperactivity disorder and prenatal alcohol exposure

BACKGROUND

An improved understanding of the neurodevelopmental differences between attention deficit hyperactivity disorder with and without prenatal alcohol exposure (ADHD + PAE and ADHD-PAE, respectively) is needed. Herein, we evaluated gyrification (cortical folding) in children with ADHD + PAE compared to that in children with familial ADHD-PAE and typically developing (TD) children.

METHODS

ADHD + PAE (n = 37), ADHD-PAE (n = 25), and TD children (n = 27), aged 8-13 years, were compared on facial morphological, neurobehavioral, and neuroimaging assessments. Local gyrification index (LGI) maps were compared between groups using general linear modelling. Relationships between LGI and clincobehavioral parameters in children with ADHD ± PAE were evaluated using multivariate partial least squares.

RESULTS

ADHD + PAE and ADHD-PAE groups showed significantly lower LGI (relative to TD) in numerous regions, overlapping in medial prefrontal, parietal, and temporo-occipital cortices (p < 0.001). However, LGI in left mid-dorsolateral prefrontal cortex was uniquely lower in the ADHD + PAE group (p < 0.001). Partial least squares analysis identified one significant latent variable (accounting for 59.3 % of the crossblock correlation, p < 0.001), reflecting a significant relationship between a profile of lower LGI in prefrontal (including left mid-dorsolateral), insular, cingulate, temporal, and parietal cortices and a clinicobehavioral profile of PAE, including a flat philtrum and upper vermillion border, lower IQ, poorer behavioral regulation scores, and greater hyperactivity/impulsivity.

CONCLUSIONS

Children with ADHD + PAE uniquely demonstrate lower mid-dorsolateral LGI, with widespread lower LGI related to more severe facial dysmorphia and neurobehavioral impairments. These findings add insight into the brain bases of PAE symptoms, potentially informing more targeted ADHD treatments based on an objective differential diagnosis of ADHD + PAE vs. ADHD-PAE.

[Formula: see text] Cognitive and social/emotional influences on adaptive functioning in children with FASD: Clinical and cultural considerations

Fetal Alcohol Spectrum Disorder (FASD) is one of the leading causes of intellectual disability and learning difficulties around the world. Children with FASD often have extremely low adaptive behavior due to the severity of brain impairment, however there is limited understanding as to the important predictors of adaptive behavior. In a study of 39 children with FASD and 29 comparison children, we found that social cognition (specifically recognizing emotions) was the only significant independent predictor of teacher-rated adaptive functioning even after including IQ, executive functioning, and adverse childhood experiences into the model. In this current study, Māori (Indigenous people of Aotearoa New Zealand) were overrepresented; therefore, the research was supported by a strong partnership with Te Wāhanga Hauora Māori (Māori Health Service). Aotearoa New Zealand's colonized history is recognized and findings are discussed with regard to both the psychological literature and a Te Ao Māori worldview.

Suicide risk in adolescents with fetal alcohol spectrum disorders

BACKGROUND

The teratogenic effects of prenatal alcohol exposure (PAE) have been extensively documented over the course of 45 years of research and psychiatric problems are pervasive in this population. In adults with PAE, suicidal risk is high but less is known about the suicidal risk in adolescents with fetal alcohol spectrum disorders (FASD). This study describes the prevalence of suicidal ideation and serious suicide attempts in a sample of 54 adolescents between the ages of 13 and 18 years with FASD.

METHODS

Adolescents were diagnosed with FASD using the Updated Clinical Guidelines for Diagnosing Fetal Alcohol Spectrum Disorders. The Children's Interview for Psychiatric Syndromes was used to identify those adolescents who experienced suicidal ideation and/or who had made a serious suicide attempt in the last 12 months.

RESULTS

The prevalence of suicidal behaviors in this sample was high with 35.2% of teens reporting incidences of suicidal ideation and 13.0% reporting at least one serious suicide attempt in the past year. This finding is in contrast to the 17.2% and 2.4% for ideation and serious attempts, respectively, reported in the general U.S. adolescent population. Alarmingly, 29.2% of males with FASD reported a serious suicide attempt which was 19½ times higher than national norms for males. No females reported attempts. Number of home placements and the presence of a depressive disorder contributed to study outcomes.

CONCLUSIONS

Findings demonstrate the significant risk for suicidality in this population, particularly adolescent males, and the need to assess and treat this life threatening behavior.

Forty Years of Assessing Neurodevelopmental and Behavioral Effects of Prenatal Alcohol Exposure in Infants: What Have We Learned?

It has been known for over 4 decades that prenatal alcohol exposure (PAE) can adversely affect neurodevelopment and behavior (NDB). Yet, early detection of altered NDB due to PAE continues to present a major clinical challenge. Identification of altered NDB in the first 2 years of life, before higher-order cognitive processes develop, invites early interventions for affected children to improve long-term outcomes. Studies published in English from January of 1980 to July of 2018 were identified in PubMed/MEDLINE. The review focused on prospective birth cohort studies which used standardized NDB assessments in children up to 2 years of age, wherein PAE was the main exposure and NDB was the main outcome. NDB was categorized into the domains of neurocognitive, adaptive, and self-regulation based on the 2016 Updated Clinical Guidelines for Diagnosing fetal alcohol spectrum disorder. An initial search resulted in 1,867 articles for which we reviewed abstracts; 114 were selected for full-text review; and 3 additional abstracts were identified through review of references in eligible publications. Thirty-one publications met criteria and were included: of these, 24 reported neurocognitive outcomes, 24 reported adaptive behavior outcomes, and 12 reported outcomes in the domain of self-regulation. Although self-regulation was assessed in the fewest number of studies, 8/12 (75%) reported PAE-associated deficits. In contrast, results were mixed for the other 2 domains: 13/24 (54%) of the selected studies that included neurocognitive outcomes showed poorer performance following PAE, and 8/24 (33%) studies that assessed adaptive functioning found significant differences between PAE and comparison infants. There is considerable evidence to support the value of early-life assessments of infant NDB when PAE is known or suspected. More studies focusing on infant self-regulation, in particular, are needed to determine the utility of early evaluation of this critical developmental domain in infants with PAE.

Risk for Childhood Internalizing and Externalizing Behavior Problems in the Context of Prenatal Alcohol Exposure: A Meta-Analysis and Comprehensive Examination of Moderators

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.

Altered functional connectivity during spatial working memory in children with heavy prenatal alcohol exposure

Individuals prenatally exposed to alcohol often have impaired spatial working memory (SWM). This study examines functional connections of frontal and parietal regions that support SWM in children with and without prenatal alcohol exposure. Children ages 10 to 16 with histories of heavy prenatal alcohol exposure (AE group; n = 18) and controls (CON group; n = 19) underwent functional magnetic resonance imaging (fMRI) while performing a SWM task. Whole brain task-related functional connectivity of bilateral dorsolateral prefrontal cortex (DLPFC) and posterior parietal cortex (PPC) seed regions were estimated for each participant using a psychophysiological interaction approach. Children in the AE group were less accurate than children in the CON group when performing the SWM task (p = 0.008). Positive coupling between bilateral DLPFC seeds and regions within the fronto-parietal network was observed in the CON group, whereas the AE group showed negative connectivity. In contrast to the CON group, the AE group showed positive connectivity between PPC seeds and frontal lobe regions. Across seeds, decreased negative coupling with regions outside the fronto-parietal network (e.g., left middle occipital gyrus) were observed in the AE group relative to the CON group. Functional data clusters were considered significant at p < 0.05. Overall findings suggest that localized alterations in neural activity, aberrant fronto-parietal network synchrony, and poor coordination of neural responses with regions outside of this network may help explain SWM deficits in individuals with a history of heavy prenatal alcohol exposure.

Fetal Alcohol Spectrum Disorders (FASD) and competency to stand trial (CST): Suggestions for a 'best practices' approach to forensic evaluation

Fetal Alcohol Spectrum Disorders (FASD), an umbrella term for neurodevelopmental conditions caused by prenatal alcohol exposure, is overrepresented in the U.S. juvenile and adult criminal justice systems. The brain damage in FASD manifests in a combination of cognitive and adaptive impairments that potentially reduce ability to function adequately during the criminal justice process, including capacity to stand trial (CST). Despite the high risk of arrest and conviction in this population, relatively little research guides CST assessment for defendants who have or may have FASD. Therefore, the purpose of this article is to describe how FASD may affect CST and suggest ways forensic professionals might modify assessment protocols to address possible effects of FASD-associated impairments on adjudicative capacity.

Latest Evidence on Alcohol and Pregnancy

Alcohol increases risk for miscarriage, birth defects and other problems, and it is the sole cause of the range of physical, developmental and cognitive problems known as fetal alcohol spectrum disorders (FASD), which can affect up to 5 percent of all pregnancies. Many women report drinking early in pregnancy, often before they know they're pregnant. When knowledgeable of the latest research evidence, nurses can counsel women of the risks alcohol use poses to a healthy pregnancy.

Inattention and impulsivity associated with prenatal alcohol exposure in a prospective cohort study with 11-years-old Brazilian children

This paper aimed to examine prenatal alcohol exposure and neuropsychological parameters and its relationship to impulsivity and inattention. Longitudinal prospective case-control cohort study starting with the risk drinking assessment of 449 third-trimester pregnant women, and a follow-up phase with 56 mother-child pairs (28 alcohol-exposed versus 28 non-exposed), with 11-12 years old children. The cohort study was followed up for 11 years. Quantity-frequency structured questions as well as AUDIT and T-ACE questionnaires were used to assess maternal alcohol consumption. A comprehensive set of neuropsychological testing instruments was used, including d2 Test, RCFT, RAVLT, WISC-III, among others. To control low IQ effects and intellectual disability diagnoses, as well differences in school skills biasing the neuropsychological comparison assessment, children with IQ <70 or learning disabilities were excluded of the sample. The two groups showed to be very comparable regarding sex, age, schooling, global IQ, laterality and maternal and social risk factors. Significant statistical differences were found for higher speed processing, total errors, and number of omission errors in the d2 Test. Likewise, there were differences found on RCFT test (lower scores for copy, immediate and delayed recall), and on semantic verbal fluency tests with a lower score. Prenatal alcohol-exposed children seems to be more inattentive and impulsive; they have poorer skills in verbal fluency, visuospatial working memory, and executive processing when compared to non-exposed children who were part of the same cohort sample.

Neurobehavioral Disorder Associated With Prenatal Alcohol Exposure

Children and adolescents affected by prenatal exposure to alcohol who have brain damage that is manifested in functional impairments of neurocognition, self-regulation, and adaptive functioning may most appropriately be diagnosed with neurobehavioral disorder associated with prenatal exposure. This Special Article outlines clinical implications and guidelines for pediatric medical home clinicians to identify, diagnose, and refer children regarding neurobehavioral disorder associated with prenatal exposure. Emphasis is given to reported or observable behaviors that can be identified as part of care in pediatric medical homes, differential diagnosis, and potential comorbidities. In addition, brief guidance is provided on the management of affected children in the pediatric medical home. Finally, suggestions are given for obtaining prenatal history of in utero exposure to alcohol for the pediatric patient.

Maternal drug or alcohol abuse is associated with decreased head size from mid-pregnancy to childhood

AIM

Maternal alcohol abuse is poorly recognised and causes developmental problems. This study explored the foetal central nervous systems (CNS), head circumference and psychomotor development of children exposed to drugs or alcohol during pregnancy up to 2.5 years of age.

METHODS

We recruited 23 pregnant women referred to Kuopio University Hospital, Finland, by their family doctor because of drug or alcohol abuse, and 22 control mothers. Foetal CNS parameters were measured by three-dimensional ultrasonography at the mean gestational age of 20 weeks and the Griffiths Mental Developmental Scales (GMDS), and anthropometric measurements were carried out at the mean ages of one and 2.5 years.

RESULTS

The exposed foetuses had decreased biparietal and occipito-frontal distances and head circumferences, but unchanged cerebellar volume at 20 weeks, and decreased head circumferences and length and height at birth, one and 2.5 years of age. They scored lower than the controls on the GMDS general quotient and the hearing, language and locomotor subscales at 2.5 years of age.

CONCLUSION

Maternal alcohol or drug exposure was associated with decreased head size from mid-pregnancy to childhood and reduced development at 2.5 years. Foetal head circumference at mid-pregnancy was a useful indicator of substance abuse affecting the CNS.

Research Review: Executive function deficits in fetal alcohol spectrum disorders and attention-deficit/hyperactivity disorder - a meta-analysis

BACKGROUND

Attention-deficit/hyperactivity disorder (ADHD)-like symptoms are common in fetal alcohol spectrum disorders (FASD). FASD and ADHD groups both display executive function impairments; however, there is ongoing debate whether the pattern and magnitude of executive function deficits differs between these two types of disorders.

METHODS

An electronic literature search was conducted (PubMed, PsychInfo; 1972-2013) to identify studies comparing the executive functioning of children with FASD with ADHD or control groups. FASD groups included those with and without dysmorphy (i.e., FAS, pFAS, ARND, and other FASD diagnoses). Effect sizes (Hedges' g, standardized mean difference) were calculated. Random effects meta-analytic models were performed using the metafor package for R.

RESULTS

Fifty-one studies met inclusion criteria (FASD N = 2,115; ADHD N = 453; controls N = 1,990). Children with FASD showed the strongest and most consistent deficits in planning, fluency, and set-shifting compared to controls (Hedges' g = -0.94, -0.78) and children with ADHD (Hedges' g = -0.72, -0.32). FASD was associated with moderate to large impairments in working memory, compared to controls (Hedges' g = -.84, -.58) and small impairments relative to groups with ADHD (Hedges' g = -.26). Smaller and less consistent deficits were found on measures of inhibition and vigilance relative to controls (Hedges' g = -0.52, -0.31); FASD and ADHD were not differentiated on these measures. Moderator analyses indicated executive dysfunction was associated with older age, dysmorphy, and larger group differences in IQ. Sex and diagnostic system were not consistently related to effect size.

CONCLUSIONS

While FASD is associated with global executive impairments, executive function weaknesses are most consistent for measures of planning, fluency, and set-shifting. Neuropsychological measures assessing these executive function domains may improve differential diagnosis and treatment of FASD.

Establishment of the South-Eastern Norway Regional Health Authority Resource Center for Children with Prenatal Alcohol/Drug Exposure

This paper presents a new initiative in the South-Eastern Health Region of Norway to establish a regional resource center focusing on services for children and adolescents aged 2–18 years with prenatal exposure to alcohol or other drugs. In Norway, the prevalence of fetal alcohol spectrum (FAS) is not known but has been estimated to be between 1 and 2 children per 1000 births, while the prevalence of prenatal exposure to illicit drugs is unknown. The resource center is the first of its kind in Scandinavia and will have three main objectives: (1) provide hospital staff, community health and child welfare personnel, and special educators with information, educational courses, and seminars focused on the identification, diagnosis, and treatment of children with a history of prenatal alcohol/drug exposure; (2) provide specialized health services, such as diagnostic services and intervention planning, for children referred from hospitals in the South-Eastern Health Region of Norway; and (3) initiate multicenter studies focusing on the diagnostic process and evaluation of interventions.

Executive Functioning in Children and Adolescents Prenatally Exposed to Alcohol: A Meta-Analytic Review

Prenatal alcohol exposure is associated with a constellation of adverse physical, neurocognitive and behavior outcomes, which comprise a continuum of disorders labeled Fetal Alcohol Spectrum Disorders (FASD). Extant research has consistently identified executive functions (EF) as a central impairment associated with FASD. Despite this, heterogeneity exists regarding the strength of the association between FASD and different EF, and this association has not yet been quantitatively synthesized. The current meta-analysis reviews 46 studies that compare children and adolescents with FASD to participants without FASD, on a variety of EF measures. In accordance with Miyake et al. Cognitive Psychology, 41, 49-100 (2000) three-factor model of EF, findings for the primary EF domains of working memory, inhibition, and set shifting are reviewed. Results indicate that children and adolescents with FASD demonstrate significant deficits across these EF, although the magnitude of effects diverged between EF, with working memory and inhibition yielding medium effects and set shifting yielding large effects. These results were moderated by sample characteristics, type of FASD diagnosis, and EF methodology. This quantitative synthesis offers novel future research directions.

Caregivers' management of schooling for their children with fetal alcohol spectrum disorder

In this article we describe a grounded theory study of how caregivers of school-aged children with fetal alcohol spectrum disorder (FASD) managed their children's schooling. We completed 30 interviews with 17 caregivers residing in a western Canadian province, as well as document analysis and 25 hours of participant observation. We used constant comparative analysis to construct our substantive theory: intertwining to fit in. The core variable is an iterative cycle caregivers used to resolve their main concerns: preventing their children from failing academically and in social interactions and preventing themselves from being regarded as unacceptable parents. To intertwine to fit in, caregivers used two strategies: orchestrating schooling and keeping up appearances. They also regulated their relationships with their children. "Intertwining to fit in" contributes to the literature on attachment and parenting and extends explanations about caregivers' advocacy for their children with FASD. The theory has implications for school personnel and practitioners, as well as researchers.

Deficits in response inhibition correlate with oculomotor control in children with fetal alcohol spectrum disorder and prenatal alcohol exposure

Children with fetal alcohol spectrum disorder (FASD) or prenatal alcohol exposure (PAE) frequently exhibit impairment on tasks measuring inhibition. The objective of this study was to determine if a performance-based relationship exists between psychometric tests and eye movement tasks in children with FASD. Participants for this dataset were aged 5-17 years and included those diagnosed with an FASD (n=72), those with PAE but no clinical FASD diagnosis (n=21), and typically developing controls (n=139). Participants completed a neurobehavioral test battery, which included the NEPSY-II subtests of auditory attention, response set, and inhibition. Each participant completed a series of saccadic eye movement tasks, which included the antisaccade and memory-guided tasks. Both the FASD and the PAE groups performed worse than controls on the subtest measures of attention and inhibition. Compared with controls, the FASD group made more errors on the antisaccade and memory-guided tasks. Among the combined FASD/PAE group, inhibition and switching errors were negatively correlated with direction errors on the antisaccade task but not on the memory-guided task. There were no significant correlations in the control group. These data suggests that response inhibition deficits in children with FASD/PAE are associated with difficulty controlling saccadic eye movements which may point to overlapping brain regions damaged by prenatal alcohol exposure. The results of this study demonstrate that eye movement control tasks directly relate to outcome measures obtained with psychometric tests that are used during FASD diagnosis, and may therefore help with early identification of children who would benefit from a multidisciplinary diagnostic assessment.
