Global intellectual ability and adaptive functioning in children with FASD with and without sentinel facial features

Background: Fetal Alcohol Spectrum Disorder (FASD) is a neurodevelopmental disorder characterized by cognitive and adaptive impairment. FASF can be presented or not with sentinel facial features (SFF). The presence of such SFF have been positively correlated with cognitive impairment in children with FASD.Objectives: The current study explores difference in global intellectual functioning and how cognition affects adaptive behavior in children with and without SFF.Methods: A total of 88 children and adolescents (55 males, 33 females) with confirmed FASD diagnosis were included in the study, of which 16 had sentinel facial features. Childrens' neuropsychological functioning was assessed using the Wechsler Intelligence Scale for Children (WISC-V) and The Behavioral Assessment of the Dysexecutive Syndromes for Children (BADS-C). Adaptive behavior was explored through the Adaptive Behavior Assessment System (ABAS-3).Results: Children with SFF performed more poorly in tasks assessing processing speed (t = 2.495, t = .020) and executive functioning (t = 4.147, t = .001). Those children also had lower IQ scores than children without SFF (t = 2.658, t = .016). BADS-C overall scaled score was related to three of the four domains of the ABAS scale (conceptual, social, and practical) but only in the group of FASD children without SFF (B = 0.547, t = .020; B = 0.544,t = .049; B = 0.431,t = .040, respectively).Conclusions: The present study founds poorer cognitive outcomes in children who have FASD with sentinel facial features. In children without SFF, stronger executive functioning is also related to significantly stronger reported conceptual, social, and practical adaptive behaviors. Better understanding of cognitive and adaptive functioning in children with FASD may help in the design of tailored evidenced-based interventions.

Automated summary

This study found that children with FASD who have sentinel facial features have poorer cognitive outcomes and lower IQ scores. In children without sentinel facial features, stronger executive functioning is related to significantly stronger conceptual, social, and practical adaptive behaviors.
