Clinical course and prognosis of Tourette syndrome

Clinical course and prognosis of Tourette syndrome

Children between the ages of 8 and 12 with Tourette syndrome (TS) have the highest frequency of tics. Tics decrease in frequency with adolescence. Leckman et al found that there is a 10 fold higher rate of tics in children with TS than in adults, and that by 18 years of age approximately 50% of children are tic free {citation id='974}. Similar numbers were found by other investigators [Burd: 2001]. Casting some doubt on this data, however, Pappert et al asked many adults with TS as children if they still had tics and half of those who said that they were tic-free were found to still have tics. [Pappert: 2003]. Associated conditions such as attention deficit disorder are likely to persist.
