DD is coming up to 9 and very clearly has tourettes. I've read a fair bit about the diagnostic criteria and she more than meets it.
She's had multiple tics at any one time since the age of 5, both physical and verbal, plus echolalia. The tics ebb and flow in their intensity, usually very frequent when a new tic develops (say every 20-30 seconds) and she has multiple tics that can run in a sequence, say a shoulder lift then a head twist then an eye roll.
School have now asked about it, plus a number of family and friends and we've just said that everything we've read says not to mention it to DD as that can increase the tic frequency. For me, it's just part of who DD is and so far, she's not seemed bothered by it and her friends haven't mentioned it or picked on her for it.
I'm aware tics can hugely reduce in teenage years, and aside from medication if they're very, very bad then CBT is the only thing you can do if you want to reduce them.
Am I unreasonable to not bother with a formal diagnosis for DD considering it doesn't seem to bother her? She already has allergies, asthma and coeliac disease so has plenty of labels in her life.
