High IQ? ADHD? Bipolar? Eye sensitivity? Loneliness? It seems little is in common beyond correlations.
There's a list of autism symptoms used diagnostically. The list above is nowhere even close. Neither High IQ is used as a diagnostic of autism (and you can have autism and low IQ), nor ADHD (hell, until recently it was the opposite: doctors used to believe you can't have both ADHD and autism), nor bipolar disorder (at best a comorbidity).
I'll give you "eye sensitivity" (sensory sensitivity), which is one of the diagnostic symptoms.
As for loneliness, that is a second order effect under certain social circumstances, not a psysiological result of autism. Might as well consider bullying a symptom.
In fact, various studies have shown that most people with ASD have a below average IQ.
Correlation is correlated with meaning, so what are you saying
And there is not always only a correlation and not a causation. People with autism, adhd etc. have a higher risk for depression and social anxiety, often induced by the experience of living with these conditions.
