Guidelines for identification and treatment of individuals with attention deficit/hyperactivity disorder and associated fetal alcohol spectrum disorders based upon expert consensus

First Evidence-Based Guideline for Interventions in FASD

Prenatal alcohol exposure causes disruptions in brain development. The resulting disorder, fetal alcohol spectrum disorder (FASD), cannot be cured, but interventions can help improve the daily functioning of affected children and adolescents and the quality of life for the entire family.The aim of the German guideline version 2024 is to provide validated and evidence-based recommendations on interventions for children and adolescents with FASD.We searched for international guidelines and performed a systematic literature review and a hand search to identify literature (published 2012-2022) on interventions for children (0-18 years) with FASD. The quality of the literature was assessed for predefined outcomes using the GRADE method (grading of recommendations, assessment, development, and evaluation). We established a multidisciplinary guideline group, consisting of 15 professional societies, a patient support group, and 10 additional experts in the field. The group agreed on recommendations for interventions based on the systematic review of the literature and formulated additional recommendations, based on clinical experience/expert evidence in a formal consensus process.No international guideline focusing on interventions for patients with FASD was found. Thirty-two publications (4 systematic reviews and 28 original articles) were evaluated. The analysis resulted in 21 evidence-based recommendations and 26 expert consensus, covering the following topics: neuropsychological functioning, adverse effects of therapy, complications/secondary conditions, quality of life, caregiver burden, knowledge of FASD, and coping and self-efficacy.The German guideline is the first internationally to provide evidence-based recommendations for interventions in children and adolescents with FASD.

The ADHD Assessment Quality Assurance Standard for Children and Teenagers (CAAQAS)

Around 5% of the children and teenagers worldwide are affected by Attention-Deficit/Hyperactivity Disorder [ADHD], making it a major public health concern. Recently, demand for assessments has substantially increased, putting strain on healthcare and waiting lists. There is concern that pressure to clear service bottlenecks is leading to variable quality and reliability of ADHD assessments in this population. The ADHD Assessment Quality Assurance Standard for Children and Teenagers [CAAQAS] aims to address this by proposing a quality framework for ADHD assessments in this population. CAAQAS is intended to complement formal training, provide support to clinicians, inform commissioners, and empower children, teenagers, and caregivers on what to expect from an assessment and assessment report. Our goal is to promote evidence-based high-quality assessments, improve diagnostic accuracy, and reduce the risks of overdiagnosis, misdiagnosis, and underdiagnosis. Seven key topics were identified by authors which guided the development of this expert consensus statement. It was agreed that a high-quality diagnostic assessment of ADHD in this population commences with advance preparation to facilitate engagement of the child or teenager and caregivers. The consensus agreed that the minimum/essential standards for assessing and diagnosing ADHD adopt a systematic approach from pre-assessment through assessment to post-diagnostic stage, enabling ADHD to be disentangled from differential diagnoses. The process applies multi-source information to inform an assessment of development history and early risk factors, history of physical, mental health and other neurodevelopmental conditions, family, educational, and social histories. Assessment of core ADHD symptoms should include specific developmentally appropriate examples of associated difficulties and impairments. Neuropsychiatric and physical comorbidities should be assessed and identified. Recommendations for report writing are intended to facilitate effective communication between ADHD specialists and other services, and we highlight the importance of linking the diagnosis to an appropriate post-diagnostic discussion. Further, we discuss core competencies required to conduct a diagnostic assessment of ADHD in children and teenagers.

Establishing a national linked database for Fetal Alcohol Spectrum Disorder (FASD) in the UK: multi-method public and professional involvement to determine acceptability and feasibility

Introduction

Fetal Alcohol Spectrum Disorder (FASD) is one of the leading non-genetic causes of developmental disability worldwide and is thought to be particularly common in the UK. Despite this, there is a lack of data on FASD in the UK.

Objective

To conduct public and professional involvement work to establish stakeholder views on the feasibility, acceptability, key purposes, and design of a national linked longitudinal research database for FASD in the UK.

Methods

We consulted with stakeholders using online workshops (one for adults with FASD [and their supporters] N = 5; one for caregivers of people with FASD (N=7), 1:1/small-team video calls/email communication with clinicians, policymakers, data-governance experts, third-sector representatives, and researchers [N=35]), and one hybrid clinical workshop (N = 17). Discussions covered data availability, benefits, challenges, and design preferences for a national pseudonymised linked database for FASD. We derived key themes from the notes and recordings collected across all involvement activities.

Results

Our tailored, multi-method approach generated high levels of stakeholder engagement. Stakeholders expressed support for a pseudonymised national linked database for FASD. Key anticipated benefits were the potential for: increased awareness and understanding of FASD leading to better support; new insights into clinical profiles leading to greater diagnostic efficiency; facilitating international collaboration; and increased knowledge of the long-term impacts of FASD on health, social care, education, economic and criminal justice outcomes. Given the rich data infrastructure established in the UK, stakeholders expressed that a national linked FASD database could be world-leading. Common stakeholder concerns were around privacy and data-sharing and the importance of retaining space for clinical judgement alongside insights gained from quantitative analyses.

Conclusions

Multi-method and multidisciplinary public and professional involvement activities demonstrated support for a national linked database for FASD in the UK. Flexible, diverse, embedded stakeholder collaboration will be essential as we establish this database.

Fetal alcohol spectrum disorder resources for health professionals: a scoping review

OBJECTIVES

This scoping review aimed to identify and critically appraise resources for health professionals to identify, diagnose, refer, and support individuals with fetal alcohol spectrum disorder (FASD)-including the extent to which the resources are appropriate for use in communities with First Nations Peoples.

METHOD

Seven peer-reviewed databases (April 2022) and 14 grey literature websites (August 2022) were searched. The reference lists of all sources that underwent full-text review were handsearched, and FASD experts were consulted for additional sources. Resources were assessed using the Appraisal of Guidelines for REsearch and Evaluation II instrument and an adapted version of the National Health and Medical Research Council FORM Framework and iCAHE Guideline Quality Checklist.

RESULTS

A total of 41 resources underwent data extraction and critical appraisal, as screening and/or diagnosis guidelines were excluded because they are covered in other reviews. Most were recently published or updated (n=24), developed in the USA (n=15, 36.6%) or Australia (n=12, 29.3%) and assisted with FASD patient referral or support (n=40). Most management guidelines scored 76%-100% on overall quality assessment (n=5/9) and were recommended for use in the Australian context with modifications (n=7/9). Most of the guides (n=15/22) and factsheets (n=7/10) received a 'good' overall score. Few (n=3/41) resources were explicitly designed for or with input from First Nations Australians.

CONCLUSION

High-quality resources are available to support health professionals providing referrals and support to individuals with FASD, including language guides. Resources should be codesigned with people living with FASD to capture and integrate their knowledge and preferences.

Machine learning algorithms to the early diagnosis of fetal alcohol spectrum disorders

Introduction

Fetal alcohol spectrum disorders include a variety of physical and neurocognitive disorders caused by prenatal alcohol exposure. Although their overall prevalence is around 0.77%, FASD remains underdiagnosed and little known, partly due to the complexity of their diagnosis, which shares some symptoms with other pathologies such as autism spectrum, depression or hyperactivity disorders.

Methods

This study included 73 control and 158 patients diagnosed with FASD. Variables selected were based on IOM classification from 2016, including sociodemographic, clinical, and psychological characteristics. Statistical analysis included Kruskal-Wallis test for quantitative factors, Chi-square test for qualitative variables, and Machine Learning (ML) algorithms for predictions.

Results

This study explores the application ML in diagnosing FASD and its subtypes: Fetal Alcohol Syndrome (FAS), partial FAS (pFAS), and Alcohol-Related Neurodevelopmental Disorder (ARND). ML constructed a profile for FASD based on socio-demographic, clinical, and psychological data from children with FASD compared to a control group. Random Forest (RF) model was the most efficient for predicting FASD, achieving the highest metrics in accuracy (0.92), precision (0.96), sensitivity (0.92), F1 Score (0.94), specificity (0.92), and AUC (0.92). For FAS, XGBoost model obtained the highest accuracy (0.94), precision (0.91), sensitivity (0.91), F1 Score (0.91), specificity (0.96), and AUC (0.93). In the case of pFAS, RF model showed its effectiveness, with high levels of accuracy (0.90), precision (0.86), sensitivity (0.96), F1 Score (0.91), specificity (0.83), and AUC (0.90). For ARND, RF model obtained the best levels of accuracy (0.87), precision (0.76), sensitivity (0.93), F1 Score (0.84), specificity (0.83), and AUC (0.88). Our study identified key variables for efficient FASD screening, including traditional clinical characteristics like maternal alcohol consumption, lip-philtrum, microcephaly, height and weight impairment, as well as neuropsychological variables such as the Working Memory Index (WMI), aggressive behavior, IQ, somatic complaints, and depressive problems.

Discussion

Our findings emphasize the importance of ML analyses for early diagnoses of FASD, allowing a better understanding of FASD subtypes to potentially improve clinical practice and avoid misdiagnosis.

Effects of prenatal alcohol exposition on cognitive outcomes in childhood and youth: a longitudinal analysis based on meconium ethyl glucuronide

BACKGROUND

Prenatal alcohol exposure (PAE) has been linked to severe, adverse child outcomes. However, little is known regarding subclinical outcomes of low/moderate PAE and its longitudinal consequences, especially regarding neurophysiological and neurocognitive development. A newborn biomarker of PAE, meconium ethyl glucuronide (EtG), has been shown to predict cognitive impairments in primary-school-aged children. The current study investigated the ongoing effects of subclinical PAE in adolescence.

METHODS

A sample of n = 96 mother-child dyads of the FRAMES/FRANCES cohort were classified into PAE/no PAE using EtG with a 10 ng/g cutoff. Mothers were recruited during pregnancy and children were assessed during primary-school age (M = 7.57, SD = 0.65, range: 6.00-9.92 years) and adolescence (M = 13.26, SD = 0.31, range: 12.79-14.20 years) on three levels: clinical (ADHD rating), neuropsychological (IQ score and performance in a go/nogo task), and neurophysiological (analysis of P3 event-related potentials (ERP) during said go/nogo task). Developmental outcomes and courses following PAE were assessed using rmANCOVAs, controlling for relevant confounders (socioeconomic status (SES), birth weight, and maternal psychopathology).

RESULTS

Neurophysiological impairments emerged for exposed children in the form of diminished attentional resource recruiting in childhood and adolescence (reduced go-P3 amplitudes) with no differences in performance. Neuropsychological testing showed a reduced IQ score for both time points with dose-dependent effects in childhood. Clinical ADHD symptoms were not significantly affected.

CONCLUSION

Subclinical PAE, as determined by meconium EtG, has negative developmental consequences on cognitive function that persist from childhood to adolescence. These findings suggest that there is no safe limit for alcohol consumption during pregnancy and that more thorough screening of alcohol consumption during pregnancy is necessary for early identification and treatment of at-risk children.

Common developmental trajectories and clinical identification of children with fetal alcohol spectrum disorders: A synthesis of the literature

At an estimated prevalence of up to five percent in the general population, fetal alcohol spectrum disorders (FASD) are the most common neurodevelopmental disorder, at least if not more prevalent than autism (2.3%). Despite this prevalence in the general population, pediatricians and other developmental specialists have thus far failed to diagnose this disability, leaving most children and adults without the supports provided for most other disabilities. This paper will provide a review of clinically relevant literature that describes the developmental challenges of children with fetal alcohol spectrum disorders and addresses similarities to and differences of FASD from other neurodevelopmental disorders such as autism and attention deficit hyperactivity disorder. A subsequent discussion will describe how a diagnosis of an FASD can establish a basis for understanding the developmental and behavioral challenges of children with an FASD, and how specific interventions can help support child development and maximize adult independence.

Fetal alcohol spectrum disorders

Alcohol readily crosses the placenta and may disrupt fetal development. Harm from prenatal alcohol exposure (PAE) is determined by the dose, pattern, timing and duration of exposure, fetal and maternal genetics, maternal nutrition, concurrent substance use, and epigenetic responses. A safe dose of alcohol use during pregnancy has not been established. PAE can cause fetal alcohol spectrum disorders (FASD), which are characterized by neurodevelopmental impairment with or without facial dysmorphology, congenital anomalies and poor growth. FASD are a leading preventable cause of birth defects and developmental disability. The prevalence of FASD in 76 countries is >1% and is high in individuals living in out-of-home care or engaged in justice and mental health systems. The social and economic effects of FASD are profound, but the diagnosis is often missed or delayed and receives little public recognition. Future research should be informed by people living with FASD and be guided by cultural context, seek consensus on diagnostic criteria and evidence-based treatments, and describe the pathophysiology and lifelong effects of FASD. Imperatives include reducing stigma, equitable access to services, improved quality of life for people with FASD and FASD prevention in future generations.

Initial study on quantitative electroencephalographic analysis of bioelectrical activity of the brain of children with fetal alcohol spectrum disorders (FASD) without epilepsy

Fetal alcohol spectrum disorders (FASD) are spectrum of neurodevelopmental conditions associated with prenatal alcohol exposure. The FASD manifests mostly with facial dysmorphism, prenatal and postnatal growth retardation, and selected birth defects (including central nervous system defects). Unrecognized and untreated FASD leads to severe disability in adulthood. The diagnosis of FASD is based on clinical criteria and neither biomarkers nor imaging tests can be used in order to confirm the diagnosis. The quantitative electroencephalography (QEEG) is a type of EEG analysis, which involves the use of mathematical algorithms, and which has brought new possibilities of EEG signal evaluation, among the other things-the analysis of a specific frequency band. The main objective of this study was to identify characteristic patterns in QEEG among individuals affected with FASD. This study was of a pilot prospective study character with experimental group consisting of patients with newly diagnosed FASD and of the control group consisting of children with gastroenterological issues. The EEG recordings of both groups were obtained, than analyzed using a commercial QEEG module. As a results we were able to establish the dominance of the alpha rhythm over the beta rhythm in FASD-participants compared to those from the control group, mostly in frontal and temporal regions. Second important finding is an increased theta/beta ratio among patients with FASD. These findings are consistent with the current knowledge on the pathological processes resulting from the prenatal alcohol exposure. The obtained results and conclusions were promising, however, further research is necessary (and planned) in order to validate the use of QEEG tools in FASD diagnostics.

Prevalence of fetal alcohol spectrum disorder in Greater Manchester, UK: An active case ascertainment study

Background

Despite high levels of prenatal alcohol exposure in the UK, evidence on the prevalence of fetal alcohol spectrum disorders (FASD) is lacking. This paper reports on FASD prevalence in a small sample of children in primary school.

Methods

A 2‐phase active case ascertainment study was conducted in 3 mainstream primary schools in Greater Manchester, UK. Schools were located in areas that ranged from relatively deprived to relatively affluent. Initial screening of children aged 8–9 years used prespecified criteria for elevated FASD risk (small for age; special educational needs; currently/previously in care; significant social/emotional/mental health symptoms). Screen‐positive children were invited for detailed ascertainment of FASD using gold standard measures that included medical history, facial dysmorphology, neurological impairment, executive function, and behavioral difficulties.

Results

Of 220 eligible children, 50 (23%) screened positive and 12% (26/220) proceeded to Phase 2 assessment. Twenty had a developmental disorder, of whom 4 had FASD and 4 were assessed as possible FASD. The crude prevalence rate of FASD in these schools was 1.8% (95% CI: 1.0%, 3.4%) and when including possible cases was 3.6% (2.1%, 6.3%). None of these children had previously been identified with a developmental diagnosis.

Conclusions

FASD was found to be common in these schools and most of these children's needs had not previously been identified. A larger, more definitive study that uses a random sampling technique stratified by deprivation level to select schools is needed to make inferences regarding the population prevalence of FASD.

Fetal alcohol spectrum disorders: an overview of current evidence and activities in the UK

Estimates for the UK suggest that alcohol consumption during pregnancy and prevalence of fetal alcohol spectrum disorder (FASD)-the most common neurodevelopmental condition-are high. Considering the significant health and social impacts of FASD, there is a public health imperative to prioritise prevention, interventions and support. In this article, we outline the current state of play regarding FASD knowledge and research in the UK, which is characterised by a lack of evidence, a lack of dedicated funding and services, and consequently little policy formulation and strategic direction. We highlight progress made to date, as well as current knowledge and service gaps to propose a way forward for UK research.

[Fetal alcohol spectrum disorders in adults]

Fetal alcohol spectrum disorders (FASD) are a common cause of a congenital developmental disability acquired in the womb due to alcohol consumption by the mother during pregnancy. The physical and mental consequences persist into adulthood. The 4‑digit code is an evidence-based method for diagnosing the full spectrum of outcomes, i.e. the full picture of fetal alcohol syndrome (FAS), partial fetal alcohol syndrome (pFAS), alcohol-related neurodevelopmental disorder (ARND) and alcohol-related birth defects (ARBD). The four key diagnostic features are (1) growth disorder, (2) facial dysmorphia, (3) central nervous system (CNS) structural and functional abnormalities and (4) prenatal alcohol exposure. Even if the disorder cannot be cured, supportive therapeutic interventions can improve the quality of life and independence and psychiatric comorbidities can be treated.

Treatment algorithm for the use of psychopharmacological agents in individuals prenatally exposed to alcohol and/or with diagnosis of fetal alcohol spectrum disorder (FASD)

Psychotropic medication treatment of individuals who have experienced prenatal alcohol exposure (PAE) has lagged behind psychosocial interventions. Multiple psychotropic medications are often prescribed for those diagnosed with a range of neurodevelopmental disabilities and impairments of PAE (neurodevelopmental disorder associated with prenatal alcohol exposure and/or fetal alcohol spectrum disorder [ND-PAE/FASD]). Despite the diverse comorbid mental disorders, there are no specific guidelines for psychotropic medications for individuals with ND-PAE/FASD. When prescribed, concerned family members and caregivers of individuals with ND-PAE/FASD reported that polypharmacy, which was typical and adverse effects render the psychotropic medications ineffective. The objective of this work was to generate a treatment algorithm for the use of psychopharmacological agents specifically for individuals with ND-PAE/FASD. The development of decision tree for use to prescribe psychotropic medications incorporated findings from previous research and the collective clinical experience of a multidisciplinary and international panel of experts who work with individuals with ND-PAE/FASD, including an algorithm specialist. After multiple meetings and discussions, the experts reached consensus on how best to streamline prescribing along neurodevelopmental clusters. These were subdivided into four ligand-specific, receptor-acting medication targets (hyperarousal, emotional dysregulation, hyperactive/neurocognitive, and cognitive inflexibility). Each cluster is represented by a list of common symptoms. The experts recommended that prescribers first ensure adequate psychosocial and environmental, including sufficient dietary, exercise, and sleep support before prescribing psychotropic medications. Treatment then progresses through three steps of psychotropic medications for each cluster. To support established treatment goals, the most function impairing clusters are targeted first.

Diagnosis and management of foetal alcohol specturm disorder

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.

Putting Fetal Alcohol Spectrum Disorder (FASD) on the Map in New Zealand: A Review of Health, Social, Political, Justice and Cultural Developments

The damaging effects of alcohol intake have long been recognised as an issue for New Zealand society since the introduction of alcohol by early settlers. In the mid-1990s, New Zealand began to acknowledge the distinct set of impairments that result from prenatal alcohol exposure that is now known as fetal alcohol spectrum disorder (FASD), which affects all facets of an individual's life, including having individual impairments as well as secondary disabilities arising from those impairments. In New Zealand, a collaborative, multidisciplinary and multiagency approach has been necessary in order to offer the best support for individuals and families who are living with FASD. In this article, the developments within New Zealand's health, justice, social and cultural sectors are traced and the work of many individual trailblazers who have put FASD on the map is acknowledged. The story of putting FASD on the map in New Zealand is one of determination, hope and opportunity, as well as recognition that there is still a long way to go.

What can be done to lessen morbidity associated with fetal alcohol spectrum disorders?

Fetal alcohol syndrome and its wider spectrum of presentation fetal alcohol spectrum disorders represent a range of disorders that are sometimes difficult to recognise as they may present in a way that overlaps with other conditions. This makes identification and recognition challenging, which increases the burden associated with the disorder. When considering the reduction in morbidity, both prevention of exposure to alcohol by the fetus and early identification of cases are required. This selective review seeks to highlight some of the complexities involved as well as highlighting the challenges. By considering populations particularly at risk to exploring the reality of alcohol risk it will seek to offer some solutions to begin the process of change.

FASD and ADHD: Are they related and How?

In this issue of the journal, consensus criteria for the diagnosis and management of attention deficit hyperactivity disorder (ADHD) in people who have fetal alcohol spectrum disorders (FASD) are presented. In the absence of an adequate body of research on diagnosis and intervention, this expert consensus opinion is a welcome advance and should provide some guidance for clinicians managing people with FASD who have a comorbid ADHD.
