##Additional reference sources  ### Reviews  David Shprecher and colleagues recently published a thoughtful, forward-looking, but concise review of Tourette research and treatment \citep{26645901}. In December, 2015, a [special issue on Tourette Syndrome](http://link.springer.com/journal/40474/topicalCollection/AC_201b22404b6bf194b90bbc19462a5d9f/page/1) appeared \citet{26440120} describe how increased motor control occurs  in the new journal *Current Developmental Disorders Reports*. Four TS adolescents along with a variety  of compensatory mechanisms. These researchers make the case that increased inhibitory capacity within higher-order motor regions, such as  the 5 articles are clinically focused \citep{Budman_2015,Hanks_2015,Coffey_2015,Greene_2015,McGuire_2015}. SMA, may adjust motor excitability.  \citet{25925326} summarize research describing neural abnormalities associated with TS and the effects of DBS. They also discuss how the findings relate to models of cortico-basal ganglia function. \citet*{26110808} have provided a general review of DBS for movement disorders and also describe some of the recent technological advances (i.e., electrode design; rechargable implantable pulse generators; closed-loop,adaptive,stimulation).  Mary Robertson \citep{26359614,26359615,26360067,26360068} reviews work that she and others colleagues  have done during her 35-year career treating TS patients and her 30 years of publishing TS research. A detailed review of the role of the autonomic nervous system in TS describes the autonomic abnormalities associated with TS and treatment approaches based on improving autonomic modulation \citep{26074752}. Another review article summarizes some of the recent advances in TS neuroimaging \citep{26543796}. This review describes how increased motor control occurs in TS adolescents along with In December, 2015,  a variety of compensatory mechanisms \citep{26440120}.

The Tourette Association at regular intervals posts links on its web page to selected scientific articles relevant to TS \citep{TA_links}.
