This review describes how increased motor control occurs in TS adolescents along with a variety of compensatory mechanisms \citep{26440120}. These researchers make the case that increased inhibitory capacity within higher-order motor regions, such as the SMA, may adjust motor excitability.  Abstracts of presentations from the 1st World Congress on Tourette Syndrome & Tic Disorders, London, 24-26 June 2015, are [available online](http://touretteworldcongress.org/). The Tourette Association at regular intervals  posts links on its web page  to selected scientific articles relevant to TSon its web page at regular intervals  \citep{TA_links}.
