A Proposed Rewriting of the DSM-5 Diagnosis of Autism
Autism Spectrum Neurotype
Proposed Diagnostic Classification: Neurodevelopmental Conditions
Autism Spectrum Neurotype (ASN) is a lifelong neurodevelopmental pattern involving distinctive ways of processing sensory and cognitive information, regulating attention and arousal, communicating, relating to others, experiencing interests, and interacting with the environment.
Autism represents a form of human neurodevelopmental diversity. Autistic characteristics are not inherently pathological. Diagnosis is appropriate when the interaction between an individual's neurodevelopmental characteristics, support needs, and environment results in clinically meaningful disability, distress, exhaustion, loss of access, or need for support.
The purpose of diagnosis is to facilitate understanding, accommodation, communication, autonomy, appropriate support, and quality of life—not to make an autistic person appear or behave more like a non-autistic person.
Diagnostic Criteria
A. Autistic Developmental Pattern
A persistent neurodevelopmental pattern characterized by both of the following:
1. Distinctive social-communication and relational style
Persistent differences in how the individual experiences, interprets, initiates, or participates in communication and social relationships. These may include differences in:
preferred frequency, intensity, duration, or form of social interaction;
conversational timing, reciprocity, topic selection, information sharing, or turn-taking;
use or interpretation of eye contact, facial expression, gesture, prosody, body language, or other nonverbal communication;
preference for direct, explicit, literal, detailed, interest-centered, or otherwise distinctive forms of communication;
development, understanding, or maintenance of relationships according to prevailing social expectations;
preference for parallel activity, shared interests, structured interaction, solitude, small groups, or a limited number of close relationships;
understanding implicit social expectations, indirect communication, ambiguity, hierarchy, or rapidly changing interpersonal contexts;
communication or social participation that varies significantly according to familiarity, sensory conditions, emotional safety, processing demands, or available regulatory capacity.
Autistic social behavior should be evaluated according to the individual's ability to communicate, exercise autonomy, develop desired relationships, and participate meaningfully—not according to conformity with non-autistic social conventions.
Reduced eye contact, atypical body language, unusual prosody, preference for solitude, parallel play, direct communication, limited conventional small talk, intense discussion of interests, or other differences from prevailing social norms are not independently evidence of dysfunction.
Social difficulty may arise from differences between autistic and non-autistic communication styles rather than from an exclusively one-sided inability of the autistic individual to relate to others.
2. Distinctive patterns of sensory processing, regulation, attention, movement, predictability, or interest
Persistent differences involving one or more of the following:
repetitive or patterned movement, speech, sound, thought, play, or object use;
sensory sensitivity, sensory seeking, reduced sensory registration, or distinctive sensory discrimination;
strong preference for predictability, preparation, routine, repetition, familiarity, or completion;
unusually focused, sustained, specialized, absorbing, or meaningful interests;
distinctive patterns of attention, including intense concentration, monotropism, difficulty shifting attention, or strong allocation of attention toward particular subjects or activities;
differences in awareness or interpretation of internal bodily states;
use of repetitive movement, sound, speech, objects, sensory experiences, or other behaviors for self-regulation, concentration, expression, communication, or pleasure;
increased regulatory demands associated with transitions, unpredictability, sensory environments, social demands, interruption, or competing demands for attention.
These characteristics should not be presumed pathological merely because they are repetitive, intense, unconventional, or visibly autistic.
Repetitive movement, vocalization, object use, or other forms of self-stimulatory behavior ("stimming") frequently serve important regulatory, communicative, sensory, emotional, or pleasurable functions.
Safe stimming should not be reduced or eliminated solely because it appears unusual, repetitive, age-incongruent, distracting to observers, or socially unconventional.
When a repetitive behavior causes physical injury, prevents the individual from participating in something they themselves want or need to do, or indicates significant unmet sensory or regulatory needs, intervention should prioritize understanding its function, increasing safety, meeting the underlying need, and developing additional regulatory options rather than simply suppressing the behavior.
B. Developmental Course
The autistic neurodevelopmental pattern originates during development, although particular characteristics may not become apparent until social, sensory, cognitive, executive, or adaptive demands exceed available capacities or accommodations.
Characteristics may also become less externally visible through development, supportive environments, learned strategies, compensation, or masking.
Recognition later in life does not imply that autism began later in life.
C. Disability, Distress, or Support Need
The interaction between the individual's neurodevelopmental characteristics and their current environment results in clinically meaningful disability, distress, exhaustion, loss of access, or need for support in one or more areas of life.
Difficulty may arise from:
characteristics intrinsic to the individual's neurodevelopmental pattern;
mismatch between the individual and their sensory, social, educational, occupational, or physical environment;
inaccessible communication expectations;
insufficient accommodation;
chronic demands for behavioral or social conformity;
discrimination or misunderstanding;
demands exceeding available executive, sensory, communicative, or regulatory capacity;
or a combination of individual and environmental factors.
Difference from prevailing developmental or social norms alone does not satisfy this criterion.
D. Differential Considerations
The neurodevelopmental pattern is not better explained in its entirety by another developmental, neurological, psychiatric, sensory, or medical condition.
Autism may coexist with intellectual disability, language disorders, ADHD, learning disorders, motor differences, anxiety disorders, mood disorders, trauma-related conditions, epilepsy, sleep disorders, feeding differences, or other developmental, psychiatric, neurological, or medical conditions.
The presence of another diagnosis does not exclude autism when an autistic developmental pattern is independently present.
Diagnostic and Treatment Safeguards
Autistic characteristics must not be classified as symptoms requiring treatment solely because they appear unusual to other people.
Clinical significance should be determined by effects on the autistic individual's safety, autonomy, communication, access, functioning, relationships, well-being, or personally meaningful goals.
Intervention should not target reduced eye contact, harmless stimming, unusual prosody, preference for solitude, direct communication, intense interests, parallel play, atypical body language, or other autistic characteristics solely for the purpose of making an individual appear non-autistic.
Particular caution should be exercised when treatment goals are based primarily on caregiver, educator, clinician, or societal discomfort rather than the autistic person's welfare.
For children and individuals who cannot fully articulate their preferences, clinicians should consider behavior, affect, engagement, avoidance, assent, distress, communication in all available forms, developmental needs, and information from people who know the individual well when evaluating whether an intervention promotes the individual's welfare.
The goal of autism support is not to make an autistic person appear non-autistic. Support should help the individual communicate, regulate, participate, develop autonomy, remain safe, form and maintain relationships they find meaningful, access their environment, and pursue a life they experience as worthwhile.
Autistic Support Needs Profile
A diagnosis of Autism Spectrum Neurotype should be accompanied by an individualized Autistic Support Needs Profile (ASNP) rather than a single global severity designation.
Support need is not a measure of intelligence, competence, maturity, potential, human capacity, or worth.
Support needs describe the assistance, accommodation, environmental conditions, or accessibility measures an individual requires to achieve communication access, regulation, autonomy, participation, safety, and quality of life.
An individual may require little or no assistance in one domain while requiring substantial assistance in another.
Support needs may also change across settings, relationships, developmental periods, life transitions, environmental conditions, and periods of illness, stress, overload, shutdown, or burnout.
Masking and Compensation
The ability to perform an activity through substantial conscious compensation or masking should not automatically be interpreted as independence.
When successful performance consistently requires an unsustainable degree of effort or results in significant exhaustion, distress, overload, shutdown, burnout, or subsequent loss of functioning, the individual's underlying support need should be documented.
Apparent competence in one environment should not invalidate evidence of support needs occurring before, during, or after participation in that environment.
Support Domains
1. Communication Access
Assessment should describe the support required for the individual to reliably understand others and communicate needs, preferences, consent, refusal, distress, ideas, questions, emotions, and experiences.
Communication may occur through speech, writing, typing, augmentative and alternative communication (AAC), sign, gesture, movement, behavior, visual systems, or combinations of modalities.
Speech should not be presumed to be inherently superior to other effective forms of communication.
Communication ability may vary substantially according to stress, sensory load, familiarity, processing demands, regulation, fatigue, or context.
2. Sensory and Regulatory Support
Assessment should describe support required to maintain or restore regulation in relation to sensory input, stimulation, arousal, internal bodily states, environmental demands, and accumulated stress.
Consideration should include sensory avoidance and sensory seeking, opportunities for movement and stimming, access to quieter or lower-demand environments, predictability, recovery time, and individualized regulatory strategies.
3. Executive Function and Transition Support
Assessment should describe support required for initiation, planning, organization, sequencing, working memory, time management, prioritization, task completion, shifting attention, transitions, interruption, and adapting to unexpected change.
Difficulty initiating or transitioning should not automatically be interpreted as laziness, defiance, lack of motivation, or unwillingness.
4. Daily Living and Adaptive Support
Assessment should describe assistance required for personally relevant activities of daily life, including eating, preparing food, hygiene, dressing, sleep routines, household tasks, transportation, healthcare, money management, medication management when applicable, education, employment, and community participation.
Ability to perform an activity occasionally should be distinguished from the ability to perform it reliably, safely, and sustainably.
5. Social Navigation and Relationship Support
Assessment should describe support required to understand, communicate, negotiate, and navigate relationships and social environments.
Support may include explicit communication, interpretation of ambiguous situations, conflict navigation, boundary recognition, self-advocacy, understanding others' intentions, relationship repair, and identifying unsafe or exploitative interpersonal situations.
The purpose of social support should be increased access, understanding, autonomy, and relationship satisfaction—not conformity to non-autistic social norms.
Autistic individuals should not be required to imitate eye contact, facial expressions, conversational styles, play styles, friendships, or other behaviors solely to appear socially typical.
6. Interoceptive and Emotional Awareness Support
Assessment should describe support required to recognize, interpret, communicate, and respond to internal bodily and emotional states.
This may include awareness of hunger, thirst, pain, temperature, fatigue, toileting needs, illness, emotional states, stress, and emerging dysregulation.
Difficulty identifying or communicating an internal state should not be interpreted as evidence that the state is absent.
7. Environmental Access and Accommodation
Assessment should describe modifications necessary for equitable and sustainable participation in home, school, employment, healthcare, community, recreational, and other environments.
Accommodations may involve sensory conditions, lighting, sound, clothing, communication format, scheduling, predictability, workload, transitions, physical space, opportunities for movement, recovery time, remote participation, or modification of social expectations.
Environmental modification is an intervention in its own right and should not be regarded as inferior to interventions directed at changing the autistic individual.
8. Safety and Vulnerability Support
Assessment should describe individualized assistance required around physical safety, danger recognition, exploitation, abuse, coercion, wandering or elopement, self-injury, crisis communication, healthcare access, emergency situations, or other relevant vulnerabilities.
Safety interventions should preserve autonomy to the greatest extent possible and should not impose restrictions merely because an individual's behavior or communication is unconventional.
Support-Need Descriptors
Each domain should be described independently using the following current support-need descriptors:
Independent / Accommodated:
The individual generally meets their needs independently when reasonable environmental accommodations and communication access are available.
Intermittent Support:
Support is helpful or necessary in particular environments, activities, transitions, periods of stress, or situations involving increased demand.
Consistent Support:
Regular support is necessary for reliable and sustainable communication, participation, regulation, access, or daily functioning within this domain.
Intensive Support:
Frequent, substantial, highly individualized, or continuous assistance is necessary within this domain.
These descriptors represent current support needs rather than severity of autism and should be revised when circumstances or needs change.
Associated Autistic Regulatory Conditions
Autistic individuals may experience periods in which environmental, sensory, cognitive, emotional, physiological, or interpersonal demands exceed available regulatory capacity.
When clinically significant, these states may be coded separately from the underlying Autism Spectrum Neurotype.
Their occurrence does not represent worsening autism and should not automatically be interpreted as behavioral noncompliance.
Autistic Overload — ASN-O
Historically and commonly referred to as an "autistic meltdown."
Autistic Overload is a temporary state of involuntary regulatory overload occurring when accumulated sensory, emotional, cognitive, interpersonal, physiological, or environmental demands exceed the individual's available capacity for regulation.
Autistic overload may involve crying, yelling, intense or repetitive movement, escape behavior, loss or reduction of speech, difficulty processing language, agitation, self-injury, aggression, or other intense expressions of distress.
Presentation varies considerably between individuals and may vary between episodes within the same individual.
Autistic overload is not inherently oppositional, manipulative, attention-seeking, intentional misconduct, or a deliberate attempt to control others.
During overload, an individual's ability to process language, inhibit behavior, make decisions, communicate, tolerate additional sensory input, or comply with expectations may be temporarily reduced.
Immediate response should prioritize physical and emotional safety, reduction of unnecessary demands, reduction of sensory load when appropriate, accessible communication, preservation of dignity, and restoration of regulation.
After recovery, support should focus on collaboratively identifying contributing conditions and increasing environmental fit, communication access, regulatory resources, predictability, opportunities for recovery, and recognition of emerging overload.
Punishment or behavioral suppression that does not address the conditions contributing to overload is not considered adequate treatment.
Repetitive movement, vocalization, pacing, rocking, pressure seeking, retreat, or other regulatory behaviors occurring before or during overload should not be interrupted solely because they appear unusual. Safe regulatory behaviors may prevent or reduce further escalation.
Autistic Shutdown — ASN-S
Autistic Shutdown is a temporary state of involuntary reduction in behavioral, communicative, cognitive, emotional, or motor availability associated with overload or depletion of regulatory capacity.
Shutdown may involve reduced or absent speech, slowed processing, withdrawal, immobility, difficulty initiating actions, diminished outward responsiveness, difficulty making decisions, increased reliance on alternative communication, or an urgent need to reduce interaction and sensory input.
An individual experiencing shutdown may remain aware of and receptive to their surroundings despite having substantially reduced capacity to demonstrate responsiveness.
Shutdown should not automatically be interpreted as refusal, defiance, indifference, intentional ignoring, lack of motivation, or lack of comprehension.
Support should emphasize safety, reduced demands, accessible communication, sensory regulation, processing time, preservation of autonomy, and recovery rather than requiring immediate return to typical functioning.
Autistic Burnout — ASN-B
Autistic Burnout is a sustained state of significantly diminished regulatory and functional capacity associated with prolonged demands exceeding an autistic individual's available resources and opportunities for recovery.
Burnout may involve:
profound or persistent exhaustion;
reduced tolerance for sensory, social, cognitive, or emotional demands;
increased need for solitude or recovery;
increased frequency or intensity of overload or shutdown;
reduced executive functioning;
temporary or prolonged reduction in reliable access to previously available skills;
reduced communication capacity;
increased difficulty masking or compensating for autistic characteristics;
increased support needs;
difficulty maintaining previous educational, occupational, relational, or daily-living demands.
Burnout is distinguished from ordinary short-term fatigue by its persistence and meaningful effects on functioning, participation, accessibility, or well-being.
Assessment should consider chronic masking, inaccessible environments, sustained sensory exposure, excessive social or executive demands, discrimination, inadequate accommodations, insufficient recovery, major transitions, cumulative stress, and prolonged expectations that exceed sustainable capacity.
The temporary loss of reliable access to a skill during burnout should not automatically be interpreted as permanent regression, unwillingness, manipulation, or loss of underlying ability.
Treatment and support should prioritize recovery, accommodation, reduction of unsustainable demands, environmental modification, communication access, restoration of autonomy, and gradual rebuilding of sustainable participation.
Rapid restoration of previous productivity or outward functioning should not be prioritized when doing so perpetuates the conditions responsible for burnout.
General Clinical Principle
Autism diagnosis should answer two questions:
How does this person's nervous system characteristically experience and interact with the world?
and
What does this person need in order to live safely, autonomously, meaningfully, and sustainably within that world?
The purpose of autism assessment and intervention is not normalization.
A successful outcome is not an autistic person who appears less autistic.
A successful outcome is an autistic person who has greater access to communication, regulation, autonomy, safety, meaningful relationships, participation, self-understanding, and a life that is sustainable and personally worthwhile.
