Sort of, at least for myself.

Granted, I only have Autism and not ADHD, but it seems to me that the top down vs bottom up descriptions I can find are innacurate.

Autistics love, demand, well defined categories, and once they are established to a logically coherent and resilient degree, they can be used as new set of tools to either start from, aim toward, or attempt to associate with other categories or specifics.

Most of the language I can find on this... tends to describe autistic 'bottom up' thinkers as basically not being able to use or construct categories, which frankly I find quite insulting, I am better with logically consistent categories than any allistic person I've ever met in the real, full stop.

Find me an allistic set theory mathematician, prove me wrong lol.

And also, this top down bottom up language or framework I am finding also misses the crucial distinction that I am making, that for an autist, thoughts are active, conscious, an autistic is rattling off their entire thought process in real time when rambling, can trace every step of it if someone is willing to listen to all of that.

Allistics largely don't, and largely can't, not without teaching themselves how to introspect and do metacognition... whereas those things are basically the default for autistics.

The sort of 'thought paralysis' that an Autistic person can experience... I would say that in fact largely comes down to the realization of a fundamental category break, that is so significant that it basically demands a total refactoring of the Autistic's consciously constructed systemic approach to analyzing/understanding ... potentially, their entire existence.

A person who doesn't care about or use categories would just brush this off, for an Autistic, it is potentially an existential crisis.

I also find it funny that a psychologist could literally just ask an Autistic person like myself how this works, what the actual train of thought is, how it works... and, unless they are also autistic, they never do, they just do their best at theorizing, and so far, well they are slowly getting there, sort of.
