Tic disorders: some key issues for DSM-V.
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 definition of motor and vocal tics; (2) simplification of the duration criterion for the tic disorders; (3) revising the term "transient tic disorder" for those with tic symptoms of less than 12-month duration; (4) establishing new tic disorder categories for those with substance induced tic disorder and tic disorder due to a general medical condition; and (5) including a motor tic only and vocal tic only specifier for the chronic motor or vocal tic disorder category.
