A very small (n=3) case series on an interesting new BT technique based on attention training to suppress tics: to be followed \citep{Schaich2020}
So far, BT is usually proposed for children above the age of ten. In this very interesting proof of concept study, Bennett et al. test a CBIT format for children ages 5-8 (n=16) and show good response (tic reduction) and acceptance. Moreover, they monitor these improvements over a one year period and speculate that early BT might alter the chronic course of tics: this is a very important subject and should be investigated in larger, longitudinal cohorts \citep{Bennett2020}
