This study provides a focused review of issues that are relevant to the nosology of the tic disorders and presents preliminary recommendations to be considered for DSM‐V. The recommended changes are designed to clarify and simplify the diagnostic criteria, reduce the use of the residual category, tic disorder not otherwise specified, and are not intended to alter substantially clinical practice or the continuity of past and future research. Specific recommendations include: (1) a more precise…

Tic disorders revisited: introduction of the term “tic spectrum disorders”
The results suggest that both disorders exist along a symptom severity continuum of which TS constitutes a more severe and CMTD a less severe form, and suggest the introduction of the term “tic spectrum disorders”, instead of using different diagnostic categories.
Improved criteria for the diagnosis of tic disorders in DSM-5

Tourette syndrome and tic disorders: a decade of progress.
Prospective longitudinal studies and randomized clinical trials have led to the refinement of several models of pathogenesis and advanced the evidence base regarding treatment options, however, fully explanatory models are needed that would allow for more accurate prognosis and the development of targeted and efficacious treatments.
