Summary
Children with fetal alcohol syndrome (FAS) showed worse neurodevelopmental outcomes than those with partial FAS (pFAS) or alcohol-related neurodevelopmental disorder (ARND). The pFAS and ARND groups had similar neurodevelopmental profiles.
Area of Science:
- Neuroscience
- Developmental Psychology
- Pediatrics
Background:
- Prenatal alcohol exposure is a leading cause of preventable birth defects.
- Fetal Alcohol Spectrum Disorders (FASD) encompass a range of conditions, including Fetal Alcohol Syndrome (FAS), partial FAS (pFAS), and Alcohol-Related Neurodevelopmental Disorder (ARND).
- Neurodevelopmental deficits are common in individuals with FASD, but comparative studies across diagnostic subtypes are crucial.
Purpose of the Study:
- To compare the neurodevelopmental profiles of children diagnosed with FAS, pFAS, and ARND.
- To investigate differences in neuropsychological functioning across these diagnostic groups.
- To utilize stringent diagnostic criteria for a more precise comparison.
Main Methods:
- A cohort of 78 foster and adopted children underwent comprehensive diagnostic evaluations.
- Children were classified into FAS, pFAS, or ARND categories using criteria stricter than current guidelines.
- Neuropsychological functioning was assessed across domains commonly affected by prenatal alcohol exposure, with multivariate and discriminant analyses used to compare groups.
Main Results:
- Children with FAS exhibited significantly lower weight, height, and head circumference compared to other groups.
- The FAS group showed the most impaired general intelligence, language-based memory, and functional communication skills.
- Executive functioning, specifically sequencing and shifting, was significantly poorer in the FAS group than in the pFAS or ARND groups.
- No significant differences in neurodevelopmental domains were found between the pFAS and ARND groups.
Conclusions:
- Children meeting strict physical criteria for FAS demonstrate significantly poorer neurodevelopmental functioning.
- The neurodevelopmental profiles of children with pFAS and ARND are comparable.
- These findings highlight the distinct impact of FAS compared to pFAS and ARND on neurodevelopment.

01:19Autism Spectrum Disorder
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

01:30Attention-Deficit/Hyperactivity Disorder
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.
