Kimberly Kitzerow holds dual Bachelor’s degrees in Education and Special Education, with a minor in Instructional Strategies, and graduated summa cum laude. She later completed Bioinformatics coursework at the University of Wisconsin–Madison, earning all A’s.
This work did not begin as a conventional institutional day job. It developed through direct necessity while supporting her daughter, then expanded through disciplined interdisciplinary synthesis into formal frameworks spanning education, biochemistry, neurology, immunology, and developmental science.
View Credentials and BackgroundTimeline
The Timeline documents the step-by-step development of the framework as it was built in real time, beginning with the initial question and progressing through the identification of biochemical mechanisms, pathway relationships, and system-level organization. It provides a chronological record of discovery rather than a retrospective reconstruction.

The Primary Source List delineates what the frameworks are by organizing the biological components they are built from, including gene-coded proteins, pathways, and regulatory systems. It defines how these components relate within the model and allows evaluation of their correspondence to established biological functions.
View Primary Source ListJigsaw Puzzle Methodology
The Jigsaw Puzzle Methodology describes how the framework was developed by constructing a biochemical network of gene-coded proteins based on functional roles, and comparing autism-related biomarkers to that network to identify points of dysregulation. This enables comparison between a biological blueprint that is approximately 99.9% conserved across the species and demographic-level variation.

Framework Structure
The framework defines a systems-level model in which stress-response activation drives shifts in biochemical pathway activity, reprioritizing function across regulatory domains. This activates epigenetic, redox-sensitive protein shunts as regulatory system effectors via the BH4 Shunt and disrupts temporal system domain cycles that govern typical development and function over time. These coordinated shifts are proposed to account for both autism traits and associated comorbid conditions through their effects on neural circuits and system-level regulation.
Independent Validation
Independent studies have reported findings that align with the mechanisms described in the framework, including stress-response activation, pathway-level dysregulation, and coordinated effects across neurological and systemic domains. These findings provide convergence at the level of biological mechanism.
View Framework and ValidationHow to Read This Framework
This framework is organized at the systems level and is intended to be evaluated as a model of coordinated biological regulation rather than isolated pathways or single-variable effects. Individual components such as specific proteins, pathways, or biomarkers are not presented as independent causes but as interacting elements within a larger regulatory structure.
The model does not propose a single causal mechanism for autism or its comorbidities. Instead, it defines how shifts in regulatory system activity, driven by stress-response activation, can produce coordinated changes across multiple domains. These effects are understood as system-level dynamics rather than discrete, independent events.
Evaluation of this framework should focus on the relationships it defines between regulatory systems, pathway activity, and functional outcomes, as well as the consistency of those relationships across independent lines of evidence.
Original frameworks built from the ground up
These frameworks were developed through protein-level synthesis using biochemical network construction from gene-coded protein function. They were not generated by summarizing existing literature, but by organizing biological findings into original systems-level models.
The first physiologically informed instructional framework designed to build the neural circuitry that produces skills and behaviors, rather than attempting to modify the skills or behaviors themselves.

Learn MoreScope and Classification of Each of Kitzerow’s Frameworks
This work spans multiple frameworks. The following clarifies the scope and evidentiary classification of each.
Brief Overview of Scope and Classification
NeuroToggle® is population wide because skill development occurs through neural connectivity encouraged by teaching pedagogy across all humans.
The application of NeuroToggle® to target the skill of speech development is n = 1 until broader studies are conducted.
Gene coded protein function is conserved across humans, making the classification of Kitzerow’s BioGene biochemical network population wide.
Autism biomarker data is demographic wide, and comparing it to Kitzerow’s BioGene biochemical network shows how the autism demographic differs from population wide biochemical activity.
NeuroToggle® (Population Wide)
NeuroToggle® describes the science of skill and behavior development through neural connectivity. Learning occurs as neural circuits are built, strengthened, expanded, and timed through instruction.
These mechanisms are grounded in human neurobiology and apply broadly across the population because all humans develop skills through neural connectivity and neuroplasticity.
Application of NeuroToggle® to the Skill of Speech (n = 1)
Using NeuroToggle® to target the specific skill of speech with Kimberly Kitzerow’s daughter when she was nonverbal represents an individual application of the framework.
The framework itself is population wide, grounded in how all humans build skills through neural connectivity. Her daughter went from nonverbal to fully conversational, but this outcome is anecdotal and classified as n = 1 until broader pilot testing or structured studies are conducted.
What is generalizable is the framework. What remains anecdotal is this specific application.
Biochemical Network (Population Wide)
The biochemical network was built using gene coded protein data. Because these proteins and their pathway functions are highly conserved (99.9%) across humans, this dataset represents population level human biology rather than individual observations.
Variability is in efficacy, not in which ones are produced. This biochemical network was organized by gene coded protein function, with efficacy impacting health.
Kitzerow’s Autism and the Comorbidities Theory (Demographic Compared to Population)
The autism theoretical model emerges by comparing autism biomarker data from the autism demographic with the population wide biochemical network.
This comparison identifies where regulatory systems within the autism demographic diverge from population biology. Because the network was organized by protein function rather than gene variants, genomic variability does not affect the outcome.
Variants influence efficacy within pathways, not which functions or pathways exist. The network remains a stable population wide reference point regardless of individual genomic differences.
BioToggles (Population Wide)
BioToggles describe the patterns of regulatory system mediated protein synthesis identified within the biochemical network.
Because they are derived from gene coded protein data and conserved biological pathways, BioToggles represent population level biology rather than individual observations.
BioDials (Population Wide)
BioDials describe the patterns of temporally regulated protein synthesis identified within the biochemical network.
Because they are derived from gene coded protein data and conserved biological pathways, BioDials represent population level biology rather than individual observations.
What the Model Does Not Claim
This framework does not propose a single causal mechanism for autism or its comorbid conditions, nor does it define a universal pathway that applies identically across individuals.
It is intended as a systems-level model of biological regulation that applies a species-level baseline of gene-coded protein function in contrast with autism biomarker data. Within this structure, it functions as a comparative framework for identifying system-level deviations and generating structured predictions rather than a fixed determinant of outcomes.
The model does not replace established diagnostic criteria or clinical practice and is not presented as a standalone basis for medical decision-making. It is designed to organize and interpret relationships between regulatory systems, pathway activity, and functional outcomes at the systems level.
Because of this, the framework does not deterministically predict outcomes across all contexts. Instead, it supports conditional prediction based on patterns of deviation within the system, allowing relationships between biological states and functional outcomes to be evaluated within defined parameters.
