Somatic complaints in childhood tic disorders.

Twenty-six children diagnosed with chronic tic disorders (18 with Gilles de la Tourette syndrome and 8 with chronic motor tic disorder) were studied for unexplained physical complaints. Compared to normal controls, an excess of somatic complaints was found in the tic disorders group; this was similar to an excess of somatic complaints in a mixed psychiatric clinic group. Medication produced no significant effect on somatic complaints for patients in the tic and psychiatric clinic groups. Within the tic disorders group, no significant correlation was found between the increased somatic complaints and the severity of anxiety, dysphoria, or movement disorder.
