I have a pet theory that holds that primarily attentive ADHD (ADHD-PI) is actually a facet of the type of autism that used to be called Asperger's.
And that ADHD, generally, is an extension just outside of the autism spectrum: possibly bridging into it with ADHD-PI if not the other ADHD classifications.
One of ADHD-PI's most noticeable traits is virtually uncontrollable daydreaming. When auditory / cognitive fatigue or fast-arriving boredom sets in, for example.
Asperger's theory is plagued by glut. Which makes the condition challenging to accurately comprehend, but at the same time doesn't necessarily imply that a lot of the theory is incorrect. Instead, it may imply complexity. Which makes sense given that this condition isn't acquired but instead is characterized by divergent brain architecture and talent / cognitive resource re-parsing from "normal". Similar in concept to an RPG game.
One facet of this glut of Asperger's theory is the school of thought that hypothesizes that Asperger's is some kind of evolutionary forward expression of a type of intelligence. Which is both generous and an unusually positive take within the glut of theory, ignoring for a moment any negatives.
My hypothesis adjusts this a bit, and proposes that Asperger's may be a type of genetically de-selected (low reproduction chance) contribution of a specific intelligence type. Which may have existed in human populations from the beginning. Implying that Aspergian intelligence, which may be associated with an increase rate in daydreaming, isn't so much a forward evolution but a population mainstay that may serve some type of function in the sense of low-rate genetic contribution.
Say having to do with visual processing that implies advanced talent in pattern processing specifically.
Some human intelligence academics, who are not involved in Asperger's research, place emphasis on pattern processing as the possible heart of it.
I can think of obvious reasons as to why whatever group genetic "intelligence" governs genetic evolution, as well as the roughly equal reproduction ratio of men and women as another example, would "want" to bias human evolution as much as possible away from a high rate of human-specific-intelligence gain. Possibly smoothing it out away from purely Aspergian expression and blending it, over time, with our other natures and talents.
