Tic attack

Hi friends,
So my 7 year old had a tic attack last night. It’s been a while since she had one, any time she has had them seems to be a night. Can I ask, what causes your tic attacks? I know Tourette’s varies heavily, but just curious. My daughter has diagnosed with Tourette’s and suspected OCD she is embarrassed of her curse word tics when she’s playing with the neighborhood kids. I’m wondering if she is trying to suppress some of her tics and that is causing them to come out at night when we’re getting ready for bed.
