The 5 Core Frameworks

Research Methodology

The Jigsaw Puzzle Methodology

How the theoretical model was built from existing biological data

The Jigsaw Puzzle Methodology explains how existing findings were organized into a coherent causal model rather than treated as isolated pieces of information.

Build the reference system Create a conserved biochemical framework from gene-coded protein function.
Compare biomarker data Map demographic-level autism biomarker findings onto that reference system.
Identify recurring dysregulation Track repeated disruptions across pathways, systems, and regulatory domains.
Reconstruct the cascade Assemble those repeated findings into the broader theoretical model.
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.

Core Framework 1

BioDials

The body’s timing systems

BioDials define the biological timing of function and development.

Ultradian
Circadian
Circannual
Development
Aging
Core Framework 2

BioToggles

The stress-response systems

BioToggles categorize regulatory system stress categories.

Immune
Metabolism
Stress Response
Cellular Repair
Nervous System
Core Framework 3

Duration

How long stress lasts

The longer stress lasts, the more it can shape development and function.

Situational Short term stress
Chronic Ongoing stress
Genetic Built in differences from the start
Core Framework 4

NeuroToggle

The educational framework used to support development

What it targets

Neural connections store how to perform skills and behaviors.

Why it matters

When those connections are disrupted, skill and behavior development is affected.

NeuroToggle uses neuroplasticity-based instructional strategies grounded in established teaching pedagogy to improve neural connectivity through instruction designed to:

Strengthen them
Expand them
Build them
Time them
Core Framework 5

Autism and the Comorbidities Theory

The outcomes of the model

Autism is a lifelong category aligned with the genetic domain, while neurodivergent traits and comorbidities are shaped across the remaining categories.

Duration determines the extent of the impact over time

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.
