599. Recognizing AuDHD: Avoiding Diagnostic Pitfalls in Co-occurring Autism and ADHD w/ Dr. Sara Woods

Click here to read the transcript

As clinical evaluators, we frequently encounter cases where diagnostic criteria overlap, leaving us to navigate the complex intersection of co-occurring neurodevelopmental conditions. In this episode, Sara Woods and I explore the emerging construct of AuDHD, examining whether the co-occurrence of Autism Spectrum Disorder and Attention-Deficit/Hyperactivity Disorder represents a distinct phenotypic presentation rather than merely two additive diagnoses. We discuss qualitative insights from community self-advocates, neurobiological evidence including gray matter variations, and the complex clinical dynamics of diagnostic overshadowing, double-counting, and autistic masking. Furthermore, we address the practicalities of selecting assessment batteries, evaluating sensory profiles, accounting for socioeconomic privileges in special interests, and navigating neurodiversity-affirming practices without abandoning diagnostic rigor.
