Okay, I see what you're saying. And I agree that nobody is sure what things other than strep cause an increase in CamK activity. However, if the cross reactive antibodies to strep are found as well, the evidence for PANDAS seems a bit stronger. But, it does beg the question of whether the antigens that stimulate the production of those antibodies are also components of other pathogens. This is why I want to see the Cunningham study funded- we need the answers.
In our case, getting physicians to help, even though there was a clear temporal relationship to positive strep cultures and my daughter's psychotic behavior, did not happen until I had evidence from the Cunningham study indicating that there might be a connection. The pediatrician was already a believer, but this gave him something to share with specialists, other than just his speculation. I hope it has and will be just as useful for others.
