Neurotypical Spectrum Disorder

Diagnostic criteria:

A. Persistent deficits in social communication and social interaction across multiple contexts, as manifested by the following, currently or by history (examples are illustrative, not exhaustive; see text):

1. Deficits in socio-emotional reciprocity, ranging, for example, from inauthentic behaviour and ritualistic patterns of conversation; to lack of linguistic directness, precision, and logical structuring of communication; to restricted view of what constitutes social interaction and failure to tolerate silence.
2. Deficits in nonverbal communicative behaviours used for social interactions, ranging, for example, from excessive reliance on eye contact for communication; to attributing excessive meaning to nonverbal gestures; to a total lack of social ability in the absence of nonverbal cues.
3. Deficits in sense of justice, fairness, and inclusivity, ranging, for example, from delusions of human hierarchy based on arbitrary social markers and lack of independent personal values; to violent or insensitive interpersonal behaviours motivated by developmentally inappropriate understandings of power and dogmatic obsessions with “normality.”

B. Vague, socially dependent patterns of behavior, interests, or activities, as manifested by at least two of the following, currently or by history (examples are illustrative, not exhaustive; see text):

1. Pathological resistance to social change, inflexible adherence to socially-defined routines, or ritualized patterns of verbal and nonverbal behaviour (e.g., extreme distress at small deviations from perceived social norms, difficulties with unexpected topic transitions, rigid thinking patterns, greeting rituals, dogmatic need to work the same job for a whole lifespan, uncritical conformity to group expectations).
2. Highly volatile, undefined interests that are abnormal in intensity or focus (e.g. lack of absorption by personal interests, strong attachment or preoccupation with social judgement over interests, excessively vague and superficial approach to interests).
3. Hyper- or hyporeactivity to sensory input or unusual interests in sensory aspects of the environment (e.g., apparent indifference to loud sounds and bright lights, lack of appreciation of sensory experience, lack of fascination with light or movement).

C. Symptoms must be present in the early developmental period (but may not become fully manifest until life demands exceed limited capacities or may be masked by learned strategies in later life).

D. Symptoms cause clinically significant impairment in personal, social, occupational, or other important areas of current functioning, when situated in a normal neurodivergent setting.

E. These disturbances are not better explained by intellectual disability (intellectual developmental disorder) or global developmental delay. Intellectual disability and neurotypical spectrum disorder frequently co-occur; to make comorbid diagnoses of neurotypical spectrum disorder and intellectual disability, sense of social independence should be below that expected for general developmental level.
