Autism is considered a "Pervasive Development Disorder."
Lack of social instinct is seen across the spectrum. By itself, it is PDD in its simplest form; ASD1. If the person is physically healthy, other traits may fail to develop in a timely fashion like speech, cognition, executive function or, in the case of my children, globally.
Severity levels are based on total need. Somebody who has failed to develop speech, but is nearly age-appropriate in every other way might be ASD1. Somebody who has a high IQ but little to no executive function might be more ASD2. Usually, ASD3 is affected more globally. (ASD2/3 severity is due to more severe co-morbid conditions.)

[NT] Executive Function Development
(When "executive function" is tested, it returns an NT age-related score.)
Thank you for your explanation.
