TikTok and tics: the possible role of social media in the exacerbation of tics during the COVID lockdown.

Background And Purpose: Over the past year, many cases with newly onset or significantly exacerbated tic disorders were observed worldwide, where some aspects of the clinical presentation or the symptomatology were atypical for established tic diagnoses. Our purpose was to describe the atypical cases and raise relevant diagnostic issues.

Methods: Consecutive cases with atypical tic presentations were documented.
