Impulsivity and attention were compared in 14 patients with TS, 16 patients with OCD and 28 healthy controls \citep{Koenn2023}. Both patients with OCD and patients with TS showed significant deficits in attention via self-assessment. The severity of tics was correlated strongly positively with attentional impulsivity. The authors conclude that a detailed interpretation of the various tools for measuring impulsive behavior is necessary.
TS Study Group from Denmark \cite{Andersen2023} published results of longitudinal study in which correlates of subtance use of pediatric patients with TS. 
Tygesen et al. \cite{Tygesen2023} compared fine motor skills in children with TS, their healthy siblings and matched healthy controls. No difference between these three groups were found.
