> 2. The diagnosis and treatment of ADHD in adults but most especially in children is extremely suspect. Last year there was a study pretty much confirming it is overdiagnosed in children. But even worse, whether ADHD is even a thing or multiple conditions wrongly bundled under a single name is basically an open question. We basically put labels on children with "problematic behaviors" like "autistic spectrum disorder" and "ADHD" and then eventually find that 30-80% of ASD children are meeting criteria for ADHD. First of all what sort of study is 30-80%? But if the higher end is true, the question strongly arises: are these even two things?

You know, just the other day I read about some brain scan study which suggested high-functioning autism looked, in brain scans, more like ADHD than like profound autism. But I think to some extent this sort of problem is inevitable if you're trying to dream up a taxonomy for conditions entirely from how they present themselves with a limited understanding of their biological basis.
