Mean composite score for core cognitive control (working memory, inhibition and mental flexibility) at T1 and T2.

<p>The figure to the left includes the entire group of children with TS (19 children), whereas the figure to the right includes only the children with TS-pure (8 children). Vertical bars denote 95% confidence intervals. TS = Tourette’s Syndrome, ADHD-C = Attention-Deficit/Hyperactivity Disorder–Combined subtype, TDC = Typically Developing Children.</p
