RT Journal Article SR Electronic T1 A rating scale for Gilles de la Tourette's syndrome JF Neurology JO Neurology FD Lippincott Williams & Wilkins SP 1542 OP 1542 DO 10.1212/WNL.37.9.1542 VO 37 IS 9 A1 Goetz, Christopher G.

YR 1987 UL http://n.neurology.org/content/37/9/1542.abstract AB We developed a rating scale for tic disorders that uses only objective criteria and accommodates the variety of tic manifestations. Using short videotaped recordings with the examiner out of the taping room, we measured five tic variables: number of body areas affected, frequency of motor tics and vocalizations, and severity of motor tics and vocalizations. The rating scale fulfilled tests for inter-rater reliability and temporal stability, and correlated well with scales used to assess global changes over prolonged periods. It objectively detected improvement in tics with neuroleptics, the one pharmacotherapy accepted to abate tics in most patients.
