Introduction: Oral narrative is the ability to retell events and represents one of the most complex levels of language organization. To date, the literature does not describe quantitative studies that can provide objective measures of the oral discourse of children and adolescents diagnosed with Autism Spectrum Disorder (ASD) or Attention-Deficit/Hyperactivity Disorder (ADHD). Objective: To investigate the oral narrative discourse of children and adolescents diagnosed with ASD and of children and adolescents with ADHD. Specific objectives: To characterize and compare the narrative retelling of children and adolescents with ADHD to the narrative discourse of children and adolescents with ASD; to describe oral narrative performance based on visual stimuli in children with ASD and ADHD; and to identify the syntactic pattern in the oral narrative discourse of children and adolescents diagnosed with ASD and ADHD. Methodology: A series-of-cases, cross-sectional, and prospective study focused on the quantitative analysis of the oral discourse of children and adolescents diagnosed with ASD or ADHD, divided into two articles: (1) evaluation of the oral narrative discourse of three children and adolescents diagnosed with ASD and seven with ADHD using the full retelling subtest of the oral narrative discourse instrument, with oral and written stimuli; (2) evaluation of the oral narrative discourse of three children and adolescents diagnosed with ASD and seven with ADHD using oral narratives obtained from randomized images and from sequential images. The Research Ethics Committee approved the study under protocol number 7.698.640. Partial results: The ADHD group produced longer, more repetitive, yet more integrated discourses. In the graphs, the discourse of the ADHD population is more spread out, with longer paths between ideas, as evidenced by larger diameters and higher average path lengths. In ASD, words connect more directly, with graphs characterized by a higher average degree. Final considerations: It is hypothesized that there will be significant differences in the participants diagnosed with ASD, with graphs characterized by recurrence attributes, compared to the group diagnosed with ADHD, who will likely be characterized by connected-component attributes.
