Tic assessment 
European Society for the Study of Tourette Syndrome (ESSTS) \cite{Szejko2022} published revised version of their guidelines for assessment of tics. As the golden standard for assessment of tics, the Yale Global Tic Severity Scale (YGTSS) was listed. Along with recomendations about assessment of tics and psychiatric comorbidities, the authors also provided assessments that facilitate the differential diagnosis and assessment of cognitive abilities, emotional functions and motor skills. 
\cite{Beeler2022} investigated tic fractality  by examining two tic time series datasets collected 6-12 months apart in children with tics using random walk models and directional statistics. The authors showed that tics are fractal in nature and tools examining this characteristic could be used to estimate tic severity and treatment effectiviness as well as possible marker for differentiating tics from functional tic-like behaviors. 
\cite{Cernera2022} proposed a new sensor-based approach for assessment of tics. The authors used a combination of electromyography and acceleration data and machine learning techniques to capture differences between tics and voluntary actions and compare those with ratings done by the experts during the modified Rush Video Rating Protocol. The accuracy of new technique was comparable with the expert consensus.
