Tics are characterized by sterotyped, purposeless, and irregularly repetitive movements and usually can be classified as chronic motor or vocal tic disorders, transient tic disorders, or Tourette's syndrome. The latter is a complex disorder associated with multiple tics and often accompanied by other conditions, such as ADHD and obsessive-compulsive disorder. Treatment can be difficult, and drug therapy should begin with agents least likely to cause problems for the patient. Education of the patient and family and support from the physician and other care providers are essential elements of effective management.
