## Tics, family and society  Using self-report data, \citet{Stewart_2015_stress} revealed that stress in parents of 74 children with Tourette syndrome was highly correlated with current ADHD symptom burden in the child (r=.57), significantly but less strongly correlated with the child's OCD symptoms (r=.40), but not correlated with current tic severity (r=.18, p=.13). The correlation of parental stress with ADHD and OCD symptom severity was present to a similar degree in 48 tic-free control children. These observations reinforce the need for psychiatric expertise for optimal clinical  management of TS.
