Can methylphenidate cause tourett like tics?

Hard to say. There is certainly evidence that kids on methylphenidate may develop tics. However, there is confusion on whether the med triggers the tics or allows them to emerge a year or more before they would have naturally. A large percentage of tic disorder/tourette kids have adhd or add. Cautious management can help both the tic issue and the add, but medical management can be difficult.
