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.

The effects of 9 months of formulated whole-egg or milk powder food products as meal or snack replacements on executive function in preadolescents: A randomized, placebo-controlled trial. Am J Clin Nutr 2022; 116:1663-1671.

Abstract
BACKGROUND Elevated brain choline is associated with better executive functions in preadolescents. Manipulating dietary choline prospectively in preadolescents using egg supplementation could improve executive functions via effects on brain cellular and neurotransmitter functions. OBJECTIVES We tested the 9-month impacts of egg supplementation on executive functions. It was hypothesized that preadolescents who consumed meal or snack replacement products containing powder made from whole eggs would have the largest improvements in executive functions after 9 months compared to those consuming similar products with either added milk powder or gelatin as a placebo. METHODS A randomized, parallel-group, double-blinded, placebo-controlled trial design was used. The executive functions of 122 preadolescents (58 females) aged 9-13 were analyzed before and after the 9-month intervention. The primary outcomes were 3 NIH Toolbox-Cognitive Battery measures of executive function: mental flexibility, working memory, and selective attention and inhibitory control. Participants were randomized to consume food products with either: 1) whole egg powder; 2) milk powder; or 3) gelatin as a placebo, all matched on macronutrient content and used as replacements for commonly consumed foods (i.e., waffles, pancakes, macaroni and cheese, ice cream, and brownies). Hypothesis testing used mixed-effects models that included physical activity and sleep scores as covariates. RESULTS A statistically significant group × time interaction for selective attention and inhibitory control was found (P = 0.049) for the milk group. This interaction resulted from no change for the placebo group and an improvement in selective attention and inhibitory control performance for the milk group by a T-score of 5.8; the effect size (d) was 0.44 SD units. Other comparisons were statistically insignificant. CONCLUSIONS Consumption of foods with added milk powder as a replacement for snacks or meals for 9 months improves selective attention and inhibitory control in preadolescents. Replacement of foods with added whole egg powder does not impact 9-month changes in preadolescent executive functions. This trial was registered at clinicaltrials.gov as NCT03739424.

Abstract
Off-topic verbosity refers to tangential discourse with excessive and irrelevant information. Previous research suggests that age-related increases in off-topic verbosity may be due to underlying changes in neurocognitive functioning. The purpose of this study was to investigate relationships between attention problems and off-topic verbosity. Young adults (n = 63) and older adults (n = 82) were administered a continuous performance test and provided speech samples, which were transcribed and rated for tangentiality, egocentrism, and quantity of speech. Overall, results found that attention problems were associated with greater tangentiality among older adults, but among young adults more attention problems were associated with lower quantity of speech. Attention problems may affect young adults' and older adult's speech in different ways, possibly reflecting differences in neurocognitive functioning or communication goals.

Abstract
Central nervous system damage resulting from prenatal exposure to alcohol, often referred to as fetal alcohol spectrum disorders (FASD), commonly manifests as lacking cognitive functioning, problem solving, impulsivity, memory, executive functioning, and social skill deficits. For individuals with FASD, these brain-based deficits translate into impulsive behaviors and poorly thought-out decision-making, coupled with an inability to anticipate and recognize the sometimes very severe consequences of their behaviors. Not unexpectedly, individuals with FASD frequently find themselves disproportionately involved in the criminal justice system and mental health services. For some individuals with FASD, these behaviors can also include firesetting. First responders, like other health and legal professionals, are often unable to recognize the behavioral indicators of FASD, primarily due to a lack of training. As a result, firesetting behaviors are often attributed to deliberate, willful acts of delinquency, a desire to damage property, thrill seeking, or as attempts for personal gain, rather than being viewed as maladaptive attempts to solve problems by individuals who lack the tools to do this in more appropriate ways. These same skill deficits also present when individuals with FASD are interviewed about their involvement in such behaviors, sometimes resulting in confabulation, suggestibility, and false confessions. Further education and training in FASD are vital for first responders if they are to better support individuals with FASD and minimize their chances of becoming involved in firesetting behaviors. Furthermore, this training and education will help ensure that first responders can intervene in more appropriately when crisis situations do occur. This article will outline key behavioral symptoms of FASD as well as provide first responders with suggestions as to how to best support individuals when FASD is suspected. The brief quote that follows highlights some of the key challenges facing individuals with FASD and how poor decision-making and impulsiveness can result in severe consequences for the individual and those around them.

Abstract
OBJECTIVE Huntington's disease (HD) is an autosomal dominant neurodegenerative disease that presents significant challenges to family communication. The investigators examined observations of communication between parents with HD and their offspring talking about the challenges of HD and explored potential correlates of their communication. METHODS The sample included parents with HD and their adolescent and young-adult offspring (N=64). Parent communication and chorea were independently coded from video recordings. Parents and offspring completed working memory assessments and self-reports of neuropsychiatric symptoms, stress, and coping. RESULTS Evidence was found for the association of observed parent-offspring communication with disease markers, psychosocial characteristics, and neurocognitive function. For parents, disease markers and working memory were correlates of communication, whereas offspring's psychiatric symptoms, stress, and coping were associated with their communication. CONCLUSIONS These findings have potential implications for clinical interventions to enhance communication and quality of life for HD families.

Abstract
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.

INTERNATIONAL JOURNAL OF LANGUAGE & COMMUNICATION DISORDERS 2021; 56:694-718. [PMID: 34137136 PMCID: PMC9292204 DOI: 10.1111/1460-6984.12644] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/27/2020] [Revised: 01/21/2021] [Accepted: 05/18/2021] [Indexed: 06/12/2023]
Abstract
BACKGROUND Prenatal alcohol exposure (PAE) is associated with growth deficits and neurodevelopmental impairment including foetal alcohol spectrum disorder (FASD). Difficulties with oral and written communication skills are common among children with PAE; however, less is known about how communication skills of adolescents who have PAE compare with those who do not. Adolescence is a critical time for development, supporting the transition into adulthood, but it is considered a high-risk period for those with FASD. AIMS We conducted a systematic review to synthesize evidence regarding oral and written communication skills of adolescents with PAE or FASD and how they compare with those with no PAE. METHODS & PROCEDURES A comprehensive search strategy used seven databases: Cochrane Library, Cinahl, Embase, Medline, PsycInfo, Eric and Web of Science. Included studies reported on at least one outcome related to oral and written communication for a PAE (or FASD) group as well as a no/low PAE group, both with age ranges of 10-24 years. Quality assessment was undertaken. MAIN CONTRIBUTION Communication skills most often assessed in the seven studies included in this review were semantic knowledge, semantic processing, and verbal learning and memory. These communication skills, in addition to reading and spelling, were commonly weaker among adolescents with PAE compared with those with no/low PAE. However, the findings were inconsistent across studies, and studies differed in their methodologies. CONCLUSIONS & IMPLICATIONS Our results emphasize that for adolescents with PAE, communication skills in both oral and written modalities should be comprehensively understood in assessment and when planning interventions. A key limitation of the existing literature is that comparison groups often include some participants with a low level of PAE, and that PAE definitions used to allocate participants to groups differ across studies. WHAT THIS PAPER ADDS What is already known on the subject PAE and FASD are associated with deficits in oral and written communication skills. Studies to date have mostly focused on children with a FASD diagnosis as well as combined groups of children and adolescents with FASD or PAE. There is a gap in what is known about oral and written communication skills of adolescents, specifically, who have PAE or FASD. This has implications for the provision of assessment and supports during a period of increased social and academic demands. What this study adds to existing knowledge This review provides systematic identification, assessment and synthesis of the current literature related to oral and written communication skills of adolescents with PAE compared with those with no/low PAE. The review revealed a small knowledge base with inconsistent methodologies and findings across studies. However, the findings overall highlight that adolescents with PAE have weaker skills in oral and written language than those with no/low PAE. Results are discussed in relation to education, social and emotional well-being, and forensic contexts. What are the potential or actual clinical implications of this work? Findings emphasize that for adolescents with PAE, comprehensive assessment of both oral and written communication skills, through both standardized and functional tasks, should be undertaken. Speech-language pathologists have a key role in assessment with individuals who have PAE.

Abstract
Children with prenatal alcohol exposure (PAE) experience a range of adverse outcomes that impact multiple domains of functioning, including cognitive, physical, mental health, behavioral, social-emotional, communication, and learning. To inform tailored clinical intervention, the current study examined the relation between caregiver-reported cognitive skills (executive function; EF) and adaptive functioning. The study conducted a secondary analyses of data provided by caregivers of 87 children and adolescents (aged 5-18 years, M = 11.7; 52% male) with confirmed PAE, including a subset (n = 70) with Fetal Alcohol Spectrum Disorder (FASD), who reported on their child's EF (Behavior Rating Inventory of Executive Function) and adaptive function (Adaptive Behavior Assessment System, 2nd Edition) skills. Findings from the current study showed that caregivers reported significantly poorer EF and adaptive functioning skills for children with PAE as compared to normative samples. Poorer behavior regulation skills were associated with all aspects of adaptive functioning (i.e., practical, conceptual, and social skills). Specifically, shifting skills emerged as the best predictor of adaptive functioning among children with PAE. These results highlight the possibility that targeting particular EF domains among individuals with PAE may benefit behavior regulation, which may also extend to adaptive skills. This highlights the need to develop EF interventions for children and adolescents who have been prenatally exposed to alcohol.

Abstract
Cognitive and functional brain alterations can occur in children with prenatal alcohol exposure (PAE). We examined the functional connectivity (FC) among regions within and between attention networks, and whether inter- and intranetwork FC moderated cognition in children with PAE (n = 37; age 12.8 ± 2.8 years) and nonexposed controls (n = 40; age 13.2 ± 2.8 years). Participants completed standardized attention and executive functioning tasks and resting state functional MRI. Inter- and intra-network FC and graph-theoretical metrics were calculated among attention network regions. Relative to controls, PAE was associated with reduced FC between the left temporoparietal junction and left ventral frontal cortex and anterior insula/frontal operculum (aI/fO), and between the left intraparietal sulcus and bilateral aI/fO. PAE was associated with increased FC between the right precuneus and intraparietal lobes, the right anterior prefrontal cortex and left ventral frontal cortex and aI/fO, and the left thalamus and dorsal frontal cortex. Graph-theoretical metrics did not differ by group. FC predicted cognitive performance, negatively in the children with PAE and positively in controls. Increased intra-network together with reduced internetwork FC suggests inefficient network specialization and impaired long-range FC among attention network regions after PAE. Results further suggest that those alterations may underlie attention and executive dysfunction in children with PAE.

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

BACKGROUND Prenatal ethanol exposure (PE) impairs midbrain dopaminergic (DA) neuron function, which might contribute to various cognitive and behavioral deficits, including attention deficits and increased addiction risk, often observed in individuals with fetal alcohol spectrum disorders. Currently, the underlying mechanisms for PE-induced deficits are unclear. PE could lead to neuroinflammation by activating microglia, which play an important role in synaptic function. In the present study, we investigated PE effects on microglial activation and DA neuron density and morphology in the ventral tegmental area (VTA). Since postnatal environmental enrichment can reduce neuroinflammation and ameliorate several PE-induced behavioral deficits, we examined if a postnatal environmental intervention strategy using neonatal handling and postweaning complex housing could reverse PE effects on VTA DA neurons and microglia. METHODS Pregnant rats received 0 or 6 g/kg/d ethanol by 2 intragastric intubations on gestation days 8 to 20. After birth, rats were reared in the standard laboratory or enriched condition. Male adult rats (8 to 12 weeks old) were used for immunocytochemistry. RESULTS The results showed that PE decreased VTA DA neuron body size in standardly housed rats. Moreover, there was a significant decrease in numbers of VTA microglial branches and junctions in PE rats, suggesting morphological activation of microglia and possible neuroinflammation. The PE effects on microglia were normalized by postnatal environmental intervention, which also decreased the numbers of microglial branches and junctions in control animals, possibly via reduced stress. CONCLUSIONS Our findings show an association between PE-induced morphological activation of microglia and impaired DA neuron morphology in the VTA. Importantly, postnatal environmental intervention rescues possible PE-induced microglial activation. These data support that environmental intervention can be effective in ameliorating cognitive and behavioral deficits associated with VTA DA neuron dysfunctions, such as attention deficits and increased addiction risk.

Abstract
Relationships between neurodevelopmental functioning and hemodynamic changes in the prefrontal cortex (PFC) were contrasted between children with prenatal alcohol exposure (PAE) and children who differed relative to their history of PAE and the presence of other neurodevelopmental impairment. For all groups, deoxygenated hemoglobin (HBR) levels in the medial PFC area were negatively related to externalizing problems and levels in the medial and right lateral PFC were positively related to errors on a cognitive inhibition task. Hemodynamic changes in the medial and right lateral PFC of children with PAE demonstrated stronger relationships to aspects of executive functioning relative to contrast groups.

Abstract
PURPOSE OF REVIEW Our understanding of the diagnosis and management of Foetal Alcohol Spectrum Disorders (FASD), has been increasingly refined in the last 45 years: This review highlights current understanding and identifies future areas for research. RECENT FINDINGS Newer techniques such as three-dimensional facial recognition and advanced brain imaging, have advanced our understanding. Despite this, there remain areas, such as the relationship with other neurodevelopmental disorders, that have been insufficiently explored. Understanding the unique management approaches required is still in its infancy. However, progress is being made to treat specific aspects in FASD. SUMMARY Foetal alcohol syndrome has progressed from identification primarily through recognition of physical stigmata, to a broad understanding of neurocognitive function in the full spectrum of alcohol exposure. Understanding of neurocognitive functioning has helped to define a specific phenotype to delineate FASD from other neurodevelopmental disorders. This review explores some of these areas and demonstrates how the field has changed since its recognition 45 years ago.
