so, Your son was 15 - and did IVIG helped him ?sometimes I'm worried that we have 'discovered' ivig treatment too late..my son is 12, allready in puberty and before IVIG he was having severe vocal and motor tics for 4 years..
Same here - my son had sever vocal and motor tics at various times over his life, the worst at age 11, which we treated successfully with antibiotics. But at 15 or so it cam back, different but definitely Pandas. IVIG definitely helped immediately - but not completely and he did backslide some. Did the second one six months later, again much better, not 100%. Today, he tics a bit but nothing debilitating. He'll be on prophylactic abx for a long time, and we test once in a while to see if anything new is on the radar. Did it help your son? I wish I'd known to do it back when he was little.
