So what are you saying, Al boy? There are no medical records for Barron? Donald Trump couldn't afford to pay for the best doctors for his son? Cut the shit! If Barron was sick in anyway, it would have been dealt with PDQ.
The guy who is being sued, was lying! No lawyer wants to take the case, because they know, once they get Barron's medical records, there will be no diagnosis of Autism there. Otherwise the Trump's wouldn't have sued to begin with.
A diagnosis of ASD is not difficult, the ADOS is the tool. I work mainly with neurodevelopmental disorders. There is variation from Aspergers to classical autism but the core deficits remain. No developmental pediatrician would miss obvious ASD. His grimacing, repetitive body movements are self stimming behaviours, there are other conditions which present with sensory dysfunction, like disintegration disorder (was on the ASD spectrum before DSM5), rett disorder, ADHD, tourettes, sensory processing disorder etc however, if autistic he would have social deficits, stereotypy, restricted interests, degrees of verbal ability etc. there are diagnostic criteria one must meet.
All psychiatry and some of neurology is subjective in a sense, but it's quite obvious when someone has schizophrenia, you don't need to measure dopamine or serotonin to see it. Just like diabetes has diagnostics, but if someone comes in with the triad, weight loss, you have suspicion that is usually correct as those things are pathognomonic.
Google has made everyone an expert on nothing, a quote out of context (not saying you are doing this) without an educated eye is useless, that's not how medicine works, otherwise no one would go to school.
