Possible Tourettes or just a habit?

[whatkungfuthat]

DS2 who is nearly 7 has an odd little twitch that he does when he gets excited, he makes a sort of "drrrrrrrrr" noise and sort of goes rigid iyswim? He has done this since he was a baby it didn't used to worry us but its not going away and, if anything, seems more pronounced.

Just for background: DS1 is ASD but DS2 doesn't display any of the same characteristics, he does however have some confidence/anxiety issues such as speaking up in class. I notice when we are out somewhere he is happy and chatty until another child he doesn't know appears then he clams up and tries to hide. I have asked for a referral to his brother's paediatrician as we have a good, long relationship.

Does anyone have any experience of Tourettes? Could this be a possibility?

It could be a tic, but that doesn't necessarily mean he has Tourettes. It's very common for kids to have tics - motor or vocal. They usually last a while and then go away.
To have Tourettes a person has to have multiple tics, and the tics are supposed to last more than one year. I can't remember the exact definition.
Try not to worry too much. If you can, take some video to show your GP or Paediatrician

DD1 has a few things she does when she's excited. She tends to judder her arms and make a funny 'zzzeeee' noise.

Interestingly, DD2 also does a funny shudder when she's excited, or worried about something.

DD3 seems to just say 'yeeeee' when she's excited...who knows?

Thanks for the replies. Slightly off topic, but I am a bit cross with the school as they brought me in on Thursday and hit me with a load of negatives about his behaviour, all to do with not speaking up in class or joining in and not completing work when an adult is not nearby. When I asked how they managed him they said they had told him he would lose playtime if he didn't do the things but had never actually followed through on it. He is by nature a grumpy little thing and has to be persuaded to do certain things. When I picked him up Thursday we had a talk about not speaking up/joining in. When I picked him up yesterday he had spoken up in class and even stood up and did a 'tell' (he had nothing to show so he just did the tell part) about the tooth fairy leaving a coin in his advent calendar on 11th Dec! So he clearly needs more firm handling and appropriate sanctions for non-compliance.

The tic thing is a separate thing but the school have asked him to be referred to his brother's paed consultant, despite him being assessed in 2010 and nothing being flagged as wrong, and I know that the if I mention the tic it more or less guarantees us an appointment. I don't think we would get one based on what the school says their concerns are. I do feel his is being judged against his brothers autism, whereas another child would have their issues put down to behaviour rather than SN.

I have suggested a Star Wars sticker chart and given them a load of Star Wars stickers for it so hopefully they will implement it. Unfortunately it was a different teacher in class yesterday afternoon but I hope his usual teacher gets told about the 'tell'. I'm sorry, it sounded like I was saying they should come down heavy on him and didn't mention the positive reinforcements, should have been clearer. It's frustrating as it didn't take much to get him to comply, just a little chat on the way home.
