Effect of Rhythmic Music Auditory Stimulation

Tourette Syndrome (TS) is a chronic neurologic disorder characterized by the childhood onset of multiple motor and phonic tics that wax and wanes over time [1]. The syndrome is common (1%) and the aetiology is complex (mostly genetic) and 90% of people have co-morbid psychiatric disorders and reduced quality of life [2]. In facts Tourette syndrome is the most common cause of tics. Other tic disorders include transient tic disorder, chronic motor tic disorder and chronic vocal tics disorder. Transient tic disorder includes both motor and vocal tics with duration of less than a year, while the latter two include motor or vocal tics, but not both, for over a year. The age at onset of Tourette syndrome ranges from 2-21 years, with a mean of 5-7 years being common [2].
