My son (7) was diagnosed with Tourette Syndrome about a month ago, after over 3 years of worsening symptoms.
Getting the diagnosis has changed nothing as CAHMS in my area do not offer any support with TS as it's neurological and not mental health. I know from a Facebook UK forum for people with Tourette syndrome and parents of children with the condition that some CAHMS services do.
We have had to engage with a private neurologist, as we were only referred to an NHS one after 2 years of tics and we're still waiting for that appointment one year later.
We had to engage with private therapist for comprehensive behaviour intervention in tics therapy as again, it's not offered in our NHS trust.
Today we saw a therapist (again, at our own cost) regarding emotional disregulation as our son has been increasingly getting angry. Told this can happen with TS and by the way doesn't your son struggle to concentrate, has anyone mention ADHD to you?
So, diagnosed or not we have found absolutely no difference in help because there just hasn't been any.
Be prepared for it to get worse though, and hopefully get better. Though it doesn't always.
We are trying to secure good professionals now who we can learn coping strategies for our son from which he can carry through his whole life just in case he's one of the unlucky ones.
We also tried magnesium supplement, zinc supplements, CBD oil and they did nothing. Again, from the FB forum we did hear some people have success so they are worth a try.
The best we can do is acknowledge these tics, understand they are involuntary even when you do feel that premonitory urge (and this is good as it can be helpful if you do try CBIT) and that yes it's a difference but it doesn't make you less worthy of a person.
Sorry for long ramble, TS has quite a presence in our every day life.
