So. According to some sources. Chris chan had no speech delay. Which would therefore mean they were misdiagnosed with Autistic Disorder and would in fact has Asperger's syndrome. It seems likely to me that chris chan actually has aspergers, or failing that Child Disintigrative Disorder. I will be refering to the disorders by shorthands IA for infantile autism, AD for autistic disorder, AS for asperger's syndrome, and CDD for child disintigrative disorder. Full explanation Firstly since this essay goes heavily into, we need to go over criteria. There is a text document attached to the post with the criteria (can't put it in due to 10k character limit. Now the best age i could find for when chris chan was first diagnosed was 5-6. Which complicates things because that would make it around 1987-1988 which could mean either infanitle autism or autistic disorder couold apply. He would absolutely meet hte criteria for infantile autism. Probably autsitic disorder (DSM-III-R) as well. It's likely he was diangosed with autistic disorder at this time but infantile autism is also possible. As for the DSM IV, From what I understand chris chan spoke normally. (they claim to have spoken at 2 months but htat's obvious bullshit so it's likely just normally) however, they went mute fater their babysitter locked them in a room. This would suggest a trauma-based mutsim not a speech delay. As such this would mean he woudln't qualify for Autistic Disorder. This would mean he has asperger's syndrome as there was no speech delay. On the other hand let's assume It was in fact a developmetnal delay. Depending on the age it happened it would classify as GDD. It's claimed in the song of chris that he was 1 1/2 at the time, Although they are not a reliable narrator. this makes it incredilby unliekly he would qaulify as having Autistic disorder. It would most lkely be Asperger's syndrome, failing that GDD. Why would they be misdiagnosed? There is probably a few reasons he might have been misdiagnosed. Firstly, When they were originally diagnosed with Autistic disorder (possibly infantile autism) The criteria that would disqualify them didnt' exist nor did Asperger's. It's possible no one checked up on that wehn the DSM-IV came out. It's also possible no one looked into why the mutism happened and it not being a speech delay (although age of speech would be a routine question). Another potential reason reason is that, in general alot doctors don't question too much disorders they've already been diagnosed with. Especially if they aren't doing a thorough psychiatric exam. Onto the psychiatric assesmsent papers we do have. Firstly it's importnat to note that as he wasn't there to be assessed for autism but for behavioural issues its' likely less atteniotn was put on that. Another major issue is, "As per his parents, he did not speak until the age of seven" however we know this isn't true. and tihs could very well be the main reason they were diagnosed as such. It's also worth noting it's clear that chris chan (possibly their parents too) lied during the assessment "He was able to function well academically" When this very clearly was not the case. IIRC he failed some classes and barely passed. So another reason could very well be the chandlers aren't telling the whole story. In conclusion, This is why chris chan likely has asperger's and was misdiagnosed with autistic disorder. Which is incredibly amusing since he hates aspies so much. Now we will never know for sure as all the disorders mentioned have since been taken out of clinical usage offically in the united states (and most other places for that matter). Chris chan woudl now be diagnosed with Autism Spectrum Disorder Level 1 most likely. P.S. Really feeling this line "And, of course, who really has no life here: Chris, or the people who obsessively document and debate everything he does?" from the whiteknighting page.
