Characteristics of the Symptoms of the Proposed ND-PAE Disorder in First Grade Children in a Community Sample

Validation of the ND-PAE Diagnosis in Children with Heavy Prenatal Alcohol Exposure

This study evaluated criteria for neurobehavioral disorder associated with prenatal alcohol exposure (ND-PAE). Kable et al. (Child Psychiatry Hum Dev 55:426, 2022) assessed the validity of this diagnosis in a sample with low exposure to alcohol. The current study expanded this assessment to a sample with a wider age range and heavier alcohol exposure. Data were collected from participants (5-17 years) with prenatal alcohol exposure (PAE) and typically developing controls at six Collaborative Initiative on Fetal Alcohol Spectrum Disorders sites using neuropsychological assessment and caregiver reports. Impairment was tested at 1SD, 1.5SD, and 2SD below the normative average and a modification of the adaptive functioning requirement was tested. Testing impairment at 1SD resulted in the highest endorsement rates in both groups. Our findings replicated the study by Kable et al. and show that current criteria captured a high rate of those with PAE and that requiring fewer adaptive functioning criteria resulted in higher sensitivity to PAE.

Adaptive, Externalizing, and Internalizing Behavior of Children with Prenatal Alcohol Exposure: A Comparison of Three Parent-Report Questionnaires

This study compared the Behavior Assessment System for Children-Third Edition (BASC-3) to the Child Behavior Checklist (CBCL) and the Vineland Adaptive Behavior Scales-Third Edition (VABS-3) in children with and without histories of prenatal alcohol exposure. Data were collected from Collaborative Initiative on Fetal Alcohol Spectrum Disorders Phase 4 sites. Caregivers rated their child's behavior using three questionnaires: BASC-3, CBCL, and VABS-3. BASC-3 Adaptive Skills, Externalizing Problems, and Internalizing Problems scores were correlated with comparable scores from the CBCL (Externalizing and Internalizing Problems) and VABS-3 (Adaptive Skills) both within and across groups. Sensitivity, specificity, and positive and negative predictive values were calculated for the BASC-3. BASC-3 sensitivity rates were 78.1%, 80.5%, and 47.0% and specificity rates were 79.4%, 80.4%, and 81.5% for Adaptive Skills, Externalizing Problems, and Internalizing Problems, respectively. Positive predictive values were 87.1%, 88.0%, and 81.9% and negative predictive values were 67.0%, 69.8%, and 46.3% for Adaptive Skills, Externalizing Problems, and Internalizing Problems, respectively. Results replicated previous reports of behavioral and adaptive difficulties in children with prenatal alcohol exposure. These findings provide support for using the BASC-3 in this population.

Current considerations for fetal alcohol spectrum disorders: identification to intervention

PURPOSE OF REVIEW

This review highlights recent findings regarding the prevalence, public health impact, clinical presentation, intervention access and conceptualization of fetal alcohol spectrum disorders (FASDs). Despite ongoing work in prevention and identification of this population, the rates of drinking during pregnancy have increased and significant gaps remain in diagnosis and intervention.

RECENT FINDINGS

Prenatal alcohol exposure is the most common preventable cause of developmental disability in the world. Research has focused on improving diagnostic clarity, utilizing technology and neuroimaging to facilitate identification, engaging broader stakeholders (including self-advocates) to inform understanding and needs, and increasing access to effective interventions. There is an emerging focus on developmental trajectories and experiences in young and middle adulthood. Public policy advocacy has also made great strides in recent years.

SUMMARY

Increases in public awareness, greater concordance of diagnostic schema, leveraged use of novel technology, and the development of targeted interventions within a holistic, strengths-based conceptualization are important considerations for this population.

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.
