Dimensional archetypes in adult neurodivergence

A way to think about adult ADHD, autism, and AuDHD as patterns of dimensions rather than categorical labels. Explore the common archetypes, key under-measured dimensions, and build a dimensional map of your own.

From your starting point tool: You may recognize yourself in one or two of these patterns. This page is exploratory — not clinical, not diagnostic.
Part 1

Beyond the DSM: existing typologies

Categorical diagnoses often fail to capture how adult presentations actually show up — particularly for high-masking, late-recognized, or AuDHD profiles. Several clinical and research frameworks have emerged to describe these patterns more functionally.

Cognitive Disengagement Syndrome

Barkley's SCT

A cluster distinct from traditional ADHD-Inattentive, characterized by daydreaming, mental fog, lethargy, and slow processing speed.

Executive Function Profiles

Brown's Model

Shifts focus entirely to six clusters of executive function — activation, focus, effort, emotion, memory, action — offering a purely dimensional approach to attention.

SPECT-Based Typology

Amen Clinics

Proposes seven types (Classic, Inattentive, Overfocused, Temporal Lobe, Limbic, Ring of Fire, Anxious). Peer-reviewed validation is limited, but its public popularity reflects the real clinical demand for dimensional profiling beyond the DSM triad.

The Female Autism Phenotype

Lai & Hull

A distinct profile (regardless of sex) marked by high camouflaging, intact superficial social mimicking, intense but socially-acceptable special interests, and high internalizing distress.

The Asperger's Legacy

Clinical Archetype

Though removed from DSM-5, this term remains a widely-used conceptual archetype for lower-support-needs, verbally-able presentations.

RDoC

NIMH Framework

Reclassifies symptoms by neural systems — Cognitive Systems for executive function, Arousal/Regulatory Systems for sensory processing, and so on.

HiTOP

Hierarchical Taxonomy

Organizes psychopathology into hierarchical, continuous dimensions rather than discrete categories — capturing trait variation that crosses diagnostic boundaries.

ESSENCE

Gillberg

Demonstrates that ADHD, Autism, and DCD share substantial early symptom overlap, requiring holistic functional profiling rather than single-diagnosis thinking.

CALM Project

Data-driven research

A machine-learning approach finding that functional cognitive profiles map very poorly to rigid DSM diagnostic boundaries.

Part 2

The AuDHD intersection

Co-occurring autism and ADHD isn't simply additive. The intersection produces a distinct interactive phenotype — with internal opposing forces (routine vs. novelty, systemizing vs. impulsivity) that create friction points standard single-diagnosis frameworks miss.

Hover the diagram to explore the dynamics.

The paradox of craving routine while seeking novelty creates a distinct pattern that requires a different assessment lens than either ADHD or autism alone.

Part 3

Two dimensions standard assessments often miss

Two axes frequently absent from off-the-shelf screening tools, but which substantially alter how an adult profile reads and what kind of support actually helps.

Masking & camouflaging

Measured by tools like the CAT-Q. High masking can invalidate observer-based assessments and strongly correlates with severe autistic burnout.

Conceptual distribution — camouflaging effort (CAT-Q range) against reported burnout / somatic distress.

Time perception profiles

Temporal processing differences are clinically significant but rarely measured. "Present-Hedonistic" (ADHD-typical) vs. "Future-Anxious" (autism-typical) orientations alter daily functioning in different ways.

Conceptual radar comparison of temporal dimensions across baseline archetypes.

Build a dimensional profile

Adjust the sliders below across five key dimensions. Watch how the combination shifts the overall pattern. This is a reflection tool — not a diagnostic instrument — meant to illustrate how functional profiles can vary across people who might share the same diagnostic label.

50

Low (authentic / observable) → High (camouflaged / exhausting)

50

Initiation (ADHD lean) → Shifting / rigidity (autism lean)

50

Hypo-reactive / seeking → Hyper-reactive / avoidant

50

Externalized / emotional impulsivity → Internalized / alexithymia

50

Time blindness (now / not now) → Future-anxious / sequenced
