HI! I am Dawn, my son is Anthony, he will be 5 in May. We live in CT. He has a brother (will be 3 in April) and a sister (will be 7 in June) as well.
Anthony started blinking A LOT around the time he started pre-k, about Sept 2006. I brought him to an eye dr thinking maybe he needed glasses (I have horrible eyes, got them from my dad who had glasses at age 4) but they said his eyes were fine. He was referred to the school OT (he was already in speech therapy, started that with the Connecticut Birth to Three program at 20 months). The OT said he has Sensory Integration Dysfunction, apraxia, hypotonia, fine motor, motor planning, and visual motor difficulty.
The blinking went away for a month or two, after he had done it from about Sept to May. Then in early July (after a bunch of vaccines, so maybe that pushed him over the edge) he started the blinking back up and, at the same time, added a couple more, including a vocal tic. I brought him to a pediatric neurologist who confirmed the above and said it is all neurological, including his oral motor issues as well. The OT had thought his tics were 'stimming', the pedi neurologist said it is not stimming, but neurological tics. She said he has neurologic impairment but didn't specify what kind, I asked. I went home and told my hubby that she must not suspect TS bcause she didn't mention it. That's what I assumed but as it turns out, I didn't realize she just didn't want to bring it up and 'shock me' or whatever.
Here are 3 short video clips I took of Anthony last summer, before the GFCF diet:
http://www.geocities.com/ives6797/anthonyvids.htmlYou can hear the verbal tic if the speakers are up a, lots of blinking and tongue/lip tic.
He is NOT like this now, on teh diet. He gets some tics back (not as bad though as it was!) if we slip from teh diet, like we did over the holidays, we let him have some things that he wasn't supposed to, and he is still ticcing some now because of that.
Oh, I also wanted to mention that DAIRY causes extreme hyperactivity for my son. I had taken him off of gluten AND dairy in early August and recently wondered if I should've done one at a time, say in case gluten was a problem but not dairy, wouldn't want to keep him off dairy I didn't have to... a few days on dairy, though, and he was SO hyperactive... he was gettting into a LOT of trouble at school and having a horrible time sleeping too! We took him off and it took I think a week (?) after the last time he had dairy before he was 'normal' again. His teachers definitely are glad we have him on the diet!
We did not have any known TS in our family, but there may have been something like OCD. I worry about my other kids, especially my younger son because I think he also may have sensory issues like Anthony, and if so, that is neurological and can go hand-in-hand.
I made a video for my son, please check it out:

THANKS!
***I should add the supplements he is on too... besides being GFCF, I also give him AFP Peptizyde chewables (enzymes for digesting gluten, casein, soy), DHA (Nordic Naturals strawberry softgels), and a daily probiotic (Nature's Plus AcidophiKidz berry).
I forgot another supplement: I recently started giving him Kensho from
http://www.ourkidsasd.com It is a formula for hyperactivity but I've also read that magnesium (which it contains) can help tics, so maybe it can be a "2 birds with one stone" kinda thing

I also rub an epsom salt cream on his back at naptime and bedtime (again, manesium), or you can put some epsom salt in the bathwater. Originally I bought an expensive cream on OurkidsASD.com but have now learned how to make my own for CHEAP. Anyway if you want the recipe just let me know.
ALso should mention that my son has sensory issues as well and gets public (school) and private OT. He also gets speech therapy at school too (been in speech since 20months, he has come a LONG way!)
