ABSTRACT
As Tourette’s syndrome (TS) has beenmore widely and thoroughly studied, it has generally been acknowledged that cases consisting of tics alone are less common than those with comorbid emotional and behavioral disorders (1-4). More often than not, clinicians treating TS are realizing that tics are not the most severe problem that many of their patients must face. To be complete, therefore, an account of the natural history of TS must include TS-associated disorders along with the appearance, progression, and regression of tics.
