Tourette Syndrome in Children

Tourette Syndrome (TS) children were administered Pei Tu Ning Feng Tang treatment. The differences in gut microbiota composition, peripheral blood stress hormones, oxidative stress markers, cytokines, neurotransmitters, and hair cortisol concentrations were observed before and after treatment. Combined with the differences in tic-like behavioral indicators, the therapeutic efficacy of Pei Tu Ning Feng Tang was evaluated. Additionally, TS children underwent two fNIRS examinations before and after treatment to quantitatively describe the activation of brain function by Pei Tu Ning Feng Tang and to investigate its neural mechanisms against tics. Scores were assessed before and after treatment using the Yale Global Tic Severity Scale (YGTSS) and the Traditional Chinese Medicine Syndrome Score Sheet for Pediatric Tourette Syndrome (Spleen Deficiency and Liver Hyperactivity Type) to observe the efficacy of the medication.

There are currently no approved medications for the treatment of anxiety in children and youth with neurodevelopmental disorders (NDDs), both common and rare. Sertraline, a selective serotonin reuptake inhibitor, has extensive evidence to support its use in children's and youth with anxiety but not within NDDs. More research is needed to confirm whether or not sertraline could help improve anxiety in children and youth with common and rare neurodevelopmental conditions. This is a pilot study, in which we plan to estimate the effect size of reduction in anxiety of sertraline vs. placebo. across rare and common neurodevelopmental disorders, and determine the best measure(s) to be used as a primary transdiagnostic outcome measure of anxiety, as well as diagnosis specific measures in future, larger-scale clinical trials of anxiety in NDDs.

The primary aim of this study is to learn more about premonitory urges (PU) when using Habit Reversal Training (HRT) to treat tics. The main focus of this study is to investigate if and when PU change during tic treatment sessions and between tic treatment sessions. Participants will: * Attend 5 study visits (approximately 1 to 1.5 hours each) for an intake, habit reversal training for 3 separate tics, and a post assessment * Attend 5 practice sessions (approximately 30 minutes each) over a week for 3 weeks (total 15 practice sessions) * Study visits and practice sessions will take place in person and online via secure videoconference
