Developmental milestones, problems with bladder and bowel control, sleep disturbances, allergies, and handedness were compared in 247 consecutive Tourette syndrome (TS) patients, 17 patients with attention-deficit disorder (ADD), 15 patients with ADD secondary to TS (ADD 2(0) TS), and 47 random controls.
None of the pure ADD patients had a score greater than 6, whereas 20% of the ADD-secondary-to-TS (ADD 2(0) TS) patients had scores greater than or equal to 9.
To determine the frequency of various behavioral manifestations, we have compared 47 random normal controls to 246 patients with TS, 17 with attention-deficit disorder (ADD), and 15 with ADD secondary to a TS gene (ADD 2(0) TS).
