Tourette syndrome is defined by which criteria?

• A. One motor tic for 3 months
• B. Both motor and vocal tics present for at least 1 year
• C. Only vocal tics for 2 years
• D. Any tic lasting more than 6 months

Answer: (B)

Tourette syndrome is diagnosed when there are multiple motor tics and at least one vocal tic, present at some time during the illness, for more than 1 year, with onset before age 18. The tics can wax and wane but must persist for over a year, and they are not due to a substance or another medical condition. Among the options, the one that states both motor and vocal tics for at least 1 year fits these criteria. Shorter durations, or having only motor or only vocal tics, do not meet the diagnostic threshold.
