I read the abstract and had the same concern. In fact I was ready to reject the whole thing, partly thanks to the blunt wording. However, I downloaded the PDF and... yeah, that's not Tourette's.
I have/had Tourette's (like most, I grew out of the worst symptoms after adolescence) and the media portrayal of it is pretty awful. These symptoms align with the portrayal, not the reality. Tourette's should be diagnosed by a neurologist, not a GP, and this doesn't sound hard to distinguish.
My concern being, once GPs start seeing this media, they are less likely to be referred to a neurologist at all. Another example: a hospital near me is denying my neuropsych referral despite a valid reason because my doctor isn't in their network. Getting to a specialist is getting harder and harder even when you do have a sympathetic GP.
