Framework Overview

Neurodivergent Biochemistry

Neurodivergent Biochemistry is the overarching framework that integrates five core frameworks, each explaining how stress shapes development and function based on the type of stress, when it occurs, and how long it lasts.

How These Fit Together

Framework Summary

Neurodivergent Biochemistry explains how stress alters development and function over time.

BioDials define biological timing, and BioToggles categorize stress activation that disrupts it.

Autism and the Comorbidities Theory defines the outcomes of these variables, while NeuroToggle® provides the educational framework used to support development.

Resources We Offer

Autism and Comorbid Traits

Autism traits and comorbid traits arise from the same underlying processes, but affect different systems in the body. Because of that, they do not respond to the same type of support.

Two Categories of Traits
Autism Traits

Educational Consulting

NeuroToggle®

  • The information for how to “do” skills and behaviors is encoded in neural circuits.
  • Neurodevelopmental conditions impact how those circuits form, which impacts skill and behavior development.
  • Neuroplasticity targets how those circuits are built and refined.
  • NeuroToggle® uses established teaching pedagogy to optimize the building, strengthening, timing, and expansion of neural circuits.
Comorbid Traits

Research and Advocacy

Neurodivergent Biochemistry

  • Neurodivergent Biochemistry studies how different categories and durations of stress activation alter development and function over time.
  • BioToggles define the categories of stress activation.
  • BioDials define the typical development and function cycles that are disrupted.
  • Kitzerow’s Autism and the Comorbidities Theoretical Model defines long-term developmental and functional outcomes.

The Breakthrough and Validation

What began as Kimberly Kitzerow's effort to help her daughter speak led to the development of NeuroToggle® and the broader frameworks that followed.

The Turning Point
  1. 2020 - The Problem

    Kimberly’s daughter was nonverbal and unable to coordinate the motor patterns required for speech.

  2. 2020 - The Shift

    When she could not blow out the candles on her fourth birthday cake, it revealed that the neural circuits required for coordinated speech were not functioning as intended.

  3. 2021 - Building NeuroToggle®

    Neuroplasticity was applied to build, strengthen, time, and expand those circuits into communication. This is the foundation of NeuroToggle®.

  4. 2022 - The Results

    Her daughter became conversational, and she began sharing their story online in the hopes of helping more children.

What Came Next
  1. 2023 – Theoretical Model

    Developed the Autism and Comorbidities Model, formed Kimberly’s Educational Resources LLC, and began writing.

  2. 2024 – Framework Expansion

    Developed Neurodivergent Biochemistry and documented the work through resources, websites, videos, and ResearchGate articles.

  3. 2024 – Education + Funding

    Crowdfunded for Bioinformatics at UW–Madison, earned all A’s, requested support, and was told a PhD was required before assistance.

  4. 2025–2026 – Validation

    Within months, independent research aligned with and validated the core pillars of this model at the mechanistic level.

Her Story

How Kimberly Kitzerow helped her nonverbal autistic daughter go from silence to speech and created Neurodivergent Biochemistry

This section is for visitors who want to learn more about the story behind the work.

What began as one child’s progress became a broader body of work on neurodevelopment, neuroplasticity, and the biological systems that shape function over time.
