What are tic disorders?
Tics are sudden, rapid, recurrent, non-rhythmic movements (motor tics) or sounds (vocal tics) that usually begin before age 18. DSM-5-TR distinguishes provisional tic disorder (under 1 year), persistent motor or vocal tic disorder and Tourette’s disorder (multiple motor and at least one vocal tic for over a year).
Causes and treatment
Genetics and differences in motor-control circuits are implicated; tics are not caused by parenting. Comprehensive Behavioral Intervention for Tics (CBIT) is recommended first-line by American Academy of Neurology guidance; medication is considered for severe cases.
