How Neurodivergent Biochemistry, Kitzerow's Theory, NeuroToggle®, and Kitzerow's Daughter's Protocol Relate
This page explains the relationship between the three core parts of Kitzerow's work. Neurodivergent Biochemistry is the study of how categories of stress impact function and development over time, leading to neurodivergent traits that impact skills and behaviors and comorbid traits that impact function and development. Kitzerow's Theory delineates the outcomes of those variables. NeuroToggle® targets the development of skills and behaviors utilizing neuroplasticity-based instructional strategies, including skills and behaviors that are impacted in autism. Kitzerow's Daughter's Protocol targets the development of neural circuitry required for speech and is anecdotal.

Learn more →The flow begins with stress categories over time
Neurodivergent Biochemistry starts with the idea that stress is not one simple input. Stress can come from different categories, move through different systems, and affect the body at different points in time.
In this model, stress is organized through two major domain types: regulatory system domains and temporal system domains. Regulatory system domains are called BioToggles. Temporal system domains are called BioDials.
This distinction matters because biological outcomes depend on what system is affected, when it is affected, and how long the disruption lasts.
BioToggles
BioToggles describe the regulatory systems that shift under stress. These include systems such as immune regulation, nervous system regulation, metabolic regulation, cellular repair, and genomic regulation.
Because BioToggles control how systems function, disruption in these domains creates an impact to function. The body may become dysregulated, remain activated too long, compensate inefficiently, or move toward allostatic overload.
BioDials
BioDials describe timing domains. They explain when biological processes occur, how long they last, and whether disruption happens during important developmental windows.
Because BioDials control timing, disruption in these domains creates an impact to development. If timing is disrupted while neural circuitry is being built, skills and behaviors may develop differently.
The central fork: function and development
The model separates function from development because they answer different questions. Function asks how body systems are operating. Development asks how systems, circuits, skills, and behaviors are being built over time.
Categories of Stress
Stress categories move through BioToggles and BioDials.
BioToggles + BioDials Are Disrupted
Regulatory systems shift, timing systems are altered, and biological development or function may be affected.
BioToggles → Impact to Function → Comorbid Traits
When regulatory system domains are disrupted, the body may not function normally. This can affect immune activity, metabolism, nervous system regulation, cellular repair, energy balance, sleep, pain, inflammation, digestion, or other system-level functions.
If dysregulation persists or exceeds the body’s ability to compensate, allostatic overload can occur.
In this structure, comorbid traits are understood as outcomes of disrupted function and system overload.
BioDials → Impact to Development → Autism Traits
When temporal system domains are disrupted, the timing of development can be affected. Neural circuits may not build, strengthen, time, or integrate in the expected way.
Because neural circuits hold the information for how to perform skills and behaviors, disruption in neural circuitry development can affect communication, speech, learning, sensory processing, regulation, motor planning, attention, and behavior.
In this structure, autism traits are understood as developmental outcomes connected to altered neural circuitry development.
Why autism traits and comorbid traits cluster
Autism traits and comorbid traits do not cluster randomly. In this model, they cluster based on the pattern of stress across systems, timing, developmental stage, and duration.
The pattern of traits depends on four variables working together:
1. Which BioToggles are active
BioToggles determine which regulatory systems are affected, such as immune, nervous system, metabolic, cellular repair, or genomic regulation.
2. Which BioDials are disrupted
BioDials determine how timing, rhythm, sequencing, and coordination are affected across development and function.
3. When disruption begins
Timing during development matters. Disruption that begins during an early developmental window can affect different circuitry or systems than disruption that begins later.
4. How long disruption lasts
Duration matters. Short-term disruption may resolve. Long-term disruption can produce sustained dysregulation, developmental effects, or allostatic overload.
Trait patterns are determined by the combination of active BioToggles, disrupted BioDials, when the disruption begins during development, and how long the disruption lasts.
What Kitzerow's Theory delineates
Kitzerow's Theory delineates the outcomes of these variables. It explains how stress categories moving through BioToggles and BioDials can produce different trait patterns depending on system involvement, timing, developmental window, and duration.
The theory explains the development side by showing why neural circuitry development may become dysregulated. When circuitry development is affected, the skills and behaviors supported by that circuitry may become delayed, inconsistent, inaccessible, or expressed differently.
The theory also explains the function side by showing why comorbid traits may emerge when regulatory systems become dysregulated or overloaded.
This is why the model is not simply saying that autism and comorbidities “go together.” It explains why they can cluster through shared upstream stress categories that affect different biological domains.
View the Jigsaw Puzzle Methodology →Where NeuroToggle® fits
NeuroToggle® fits on the development side of the model. If autism traits involve impacted skills and behaviors, and skills and behaviors depend on neural circuitry, then the practical question becomes how that circuitry can be supported.
NeuroToggle® targets the development of neural circuitry through neuroplasticity-based instructional strategies. Neuroplasticity means the brain can build and change circuits through experience. Teaching is a structured form of experience, so instruction can be used intentionally to help build skills and behaviors.
NeuroToggle® is not the same thing as the biochemical theory. The theory explains why circuitry may be impacted. NeuroToggle® explains how skill and behavior circuitry can be targeted through instruction.
- Build: create the neural pathway needed for a skill.
- Strengthen: make the pathway more reliable through repetition and use.
- Time: coordinate the pathway with sensory, motor, language, and cognitive systems.
- Expand: help the skill become more flexible across settings and demands.
Where Kitzerow's Daughter's Protocol fits
Kitzerow's Daughter's Protocol is narrower than NeuroToggle®. NeuroToggle® can apply broadly to skills and behaviors, while the protocol applies the framework to one specific skill: speech.
Speech is treated as a skill that depends on coordinated neural circuitry. It requires language processing, motor planning, oral-motor coordination, sensory feedback, timing, communication intent, and repeated developmental practice.
The protocol targets the development of the neural circuitry required for speech. It is therefore a specific application of NeuroToggle®.
The outcome is anecdotal because the speech-targeted protocol has not been formally replicated in controlled research. This classification applies to the speech outcome, not to the broader theory or to NeuroToggle® as a framework.
NeuroToggle® is broader than the protocol
NeuroToggle® describes how neural circuitry for skills and behaviors can be targeted through neuroplasticity-based instruction.
The protocol is one specific use of NeuroToggle® for speech.
The outcome is anecdotal
The daughter’s speech outcome is a case-based outcome because it has not been formally replicated.
The anecdotal classification applies to the specific speech protocol outcome, not to the full theoretical structure.
The full logic without shortcuts
Neurodivergent Biochemistry studies how categories of stress affect function and development over time.
Stress acts through BioToggles, which are regulatory system domains, and BioDials, which are temporal system domains.
BioToggles affect function. When regulatory systems are disrupted or overloaded, comorbid traits can emerge.
BioDials affect development. When developmental timing is disrupted, neural circuitry development can be altered, leading to neurodivergent traits that affect skills and behaviors.
Trait clustering depends on which BioToggles are active, which BioDials are disrupted, when the disruption begins during development, and how long the disruption lasts.
Kitzerow's Theory delineates these outcomes. NeuroToggle® targets the developmental circuitry behind skills and behaviors. Kitzerow's Daughter's Protocol applies NeuroToggle® specifically to speech.
