Discovering Autism and the Comorbidities

Kimberly Kitzerow developed a systems-based model that provides a new way to understand neurodivergence, including how to support neurodivergent learners and why autism and comorbid traits cluster through the discovery of a chronologically ordered biochemical cascade.

The Model

The Cascade

The cascade organizes how stress-response domain activation shifts biological priorities over time, including BH4-mediated resource allocation, BioDial-regulated timing changes, and patterned autism and comorbid trait clustering.

Applied Frameworks

BioToggle® and NeuroToggle®

The discovery branches into two applied frameworks: BioToggle® for regulatory system domains and comorbid trait clustering, and NeuroToggle® for autism-related skills and behaviors.
