ABSTRACT
PURPOSE: The current study aimed to investigate developmental functioning in infants and toddlers with autism spectrum disorder (ASD), seizures, cerebral palsy (CP), and atypical development. METHODS: An ANOVA was utilized to investigate the differences between neurodevelopmental group on BDI-2 developmental quotient and a MANOVA was used to investigate the differences between the groups and five developmental domains. RESULTS: The results indicated statistically significant differences in overall developmental functioning and each subdomain of the BDI-2. DISCUSSION: These findings provide the basis for further research to investigate comorbidities of the three neurodevelopmental disorders and parse out the impact of intellectual disability (ID).

PURPOSE: Due to the difficulties in differentiating between impairments associated with intellectual disability and ASD symptomology, DS often leads to delayed or misdiagnoses of ASD. METHOD: An ANOVA was run to investigate the effects of ASD risk and DS on overall developmental functioning across three groups: ASD+, DS-, and DS+ (n = 138). A MANOVA was run to investigate the differences of group on five developmental subdomains. RESULTS: The results revealed significant group differences in the overall developmental functioning and each developmental subdomain. Children in the DS+ group demonstrated significantly lower overall developmental functioning, as well as lower adaptive, cognitive, motor, and communication skills compared to their peers; however, children in the DS- group demonstrated significantly better social skills compared to their peers in the ASD+ group. DISCUSSION: These findings support the need for early screening and identification of ASD among those with DS.
