I don't think there is a straight forward answer to that question. My PANDAS daughter is 15 and severely autistic. We didn't recognize her problems with strep until she was 10 years old. Once the pattern of behaviors associated with strep episodes became obvious, I was able to look back to episodes from very early in her life when we never knew she had strep, and I could see that they were the same behaviors. So my personal opinion is that PANDAS, if it starts at a very young age, can interrupt and pervert normal development. So, I think its possible that these other "diagnosis", which are really just observed symptoms, can be caused by PANDAS. But, i don't think anybody can say for sure.
