Hi Katy
have they checked Ash for possible PANS? Not saying he has that....but imo always worth checking into.
PANS is a condition where tics, OCD and other neuropsychiatric symptoms can manifest as a result of infection, often (but not limited to) strep. TS and PANS are not mutually exclusive as someone with TS can have exacerbation due to infection.
There is a lot of info coming out about how many kids are misdiagnosed with Ts or with psychiatric disorders when in fact they have PANS
This site gives info about it
