> what leads us to treat ASD as an actual single disorder, as opposed to a billion different individual neurological profiles?
We already do treat it as the latter. The medical definition of autism is basically just any neurodevelopmental disorder that isn’t ADHD.
"Why don't we treat it as many disorders instead of just calling everything autism?"
"we do, autism is everything that isn't ADHD"
...what? I must be stroking out, but I have no idea what point you're making here...?
What a ridiculous take.
This hypothesis runs into the slight problem that autism and ADHD are highly co-occurring.
