Why is Tourette's a syndrome if it's symptoms are not transitory?

I'm not sure about the differences between disorder, disease, syndrome, and the others. However, it seems that a syndrome is a combinations of symptoms that together form a “syndrome.”

Why is Tourette's considered to be a syndrome if it has one ailment- tics?

Answer:
The diagnostic term of “Tourette's” encompasses many different symptoms - not just tics. Science might decide that a specific symptoms allows an individual to be grouped with those that have Tourette's.

That said, Tourette's is neither a disorder, disease, nor syndrome. It is merely a diagnostic label for an individual that is experiencing unrecognized supernatural influences. Those with Tourette's are God's young saints!
