Neurodivergent Biochemistry and the 5 Core Frameworks
Together, these frameworks define how biological timing, stress activation, and duration interact to shape development, function, and long-term outcomes across systems.
Key mechanisms have been independently tested
Research published by major institutions has tested mechanisms that align with the biological framework presented here.
Kitzerow’s Autism and the Comorbidities Cascade
This cascade shows how genetically locked, chronically stuck, and/or situational regulatory system activation shifts biological resource allocation through the BH4 Shunt, prioritizes survival effectors, disrupts BioDial activity, alters gene expression, and changes function and development across regulatory system domains within a multivariable stress-response system cascade.
Regulatory system activation can begin or persist in different ways
In Kitzerow’s model, regulatory system activation may be genetically locked, chronically stuck, or situational. These patterns describe whether activation is built into the system, fails to resolve, or resolves after a temporary trigger.
Activation occurs across regulatory system domains
Regulatory system domains are the BioToggles in Kitzerow’s model. They represent the major domains involved in survival, function, repair, regulation, and development.
The regulatory loop detects stress and initiates response
Homeostatic regulation depends on five core components working together in a reflex loop. A change is sensed, compared against a setpoint, interpreted by a controller, and carried out through effectors that produce the response.
The BH4 Shunt reallocates biological resources
In Kitzerow’s model, the BH4 Shunt functions as a central resource allocation mechanism. Under regulatory system activation, BH4-dependent pathways shift toward survival-focused regulatory effectors.
Regulatory domains shift toward survival-focused effectors
Regulatory system domains shift toward survival-focused function as resources are routed toward effectors needed for stress resolution. This prioritizes survival responses over typical development, repair, maintenance, and day-to-day function.
BioDial activity is disrupted
BioDials represent the ongoing flow of protein synthesis across ultradian, circadian, circannual, developmental, and age-related cycles. When BioToggles are activated, timing-based synthesis patterns are deprioritized as regulatory system effectors are prioritized to support survival.
Gene expression shifts toward survival pathways
Gene expression adapts to support survival pathways and conserve resources. This changes which proteins are prioritized, which pathways are maintained, and how regulatory domains continue responding over time.
Function and development are altered
Alterations in regulatory system domain activity and BioDial activity work together to alter function and development. These changes lead to different traits over time.
Trait outcomes emerge
Altered nervous system development → core autism traits
When regulatory activation alters nervous system development, the outcomes appear as core autism traits.
Other regulatory domains → comorbid traits
When regulatory activation alters immune, metabolic, cellular repair, genetic regulation, or other regulatory domain activity, the outcomes appear as comorbid traits.
Autism traits and comorbid traits reflect how a multivariable stress-response system cascade is expressed across regulatory system domains and biological timing systems.
Autism and Comorbid Traits
Autism traits and comorbid traits are connected, but they do not affect the same systems or require the same kind of support. This work is organized into two paths so families, educators, and researchers can find the right starting point.
Educational Consulting
NeuroToggle®
A neuroplasticity-based educational framework for building and refining the neural circuits involved in skills and behavior.
- Targets how neural pathways are built, strengthened, timed, and expanded.
- Focuses on development, learning, skill acquisition, and functional progress.
- Uses established teaching pedagogy to support neurodivergent learners.
Research and Advocacy
Neurodivergent Biochemistry
A systems-level framework for understanding how stress-response states shape long-term developmental and functional outcomes across the body.
- Explains how categories and durations of stress activation alter development and function over time.
- Uses BioToggles to define categories of stress and BioDials to define disrupted timing systems.
- Includes the Autism and the Comorbidities Theoretical Model to define broader outcomes.

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.
