From: Redox metabolism abnormalities in autistic children associated with mitochondrial disease

Cognitive and behavioral characteristics for two groups of children with autism spectrum disorder (ASD): those with mitochondrial disease (MD; ASD/MD) and those without mitochondrial disease (ASD/NoMD). Children with ASD/MD demonstrated lower scores on the Vineland Adaptive Behavior Scale-Second Edition (a) communication and (b) daily living skill subscales as compared with the ASD/NoMD children. Borderline significant differences were found between the two groups for (c) social skills as measured by the Vineland Adaptive Behavior Scale. No differences were found between the two groups on (d) language (as determined by the Preschool Language Scales or the Expressive One-Word Picture Vocabulary Test depending on the child’s age), (e) the ASQ and (f–j) subscales of the Social Responsiveness Scale (SRS).
