Tics are involuntary, sudden repetitive non-rhythmic movements and vocalizations (sounds). Tics can be classified as a motor or vocal (verbal) and simple or complex. Motor tics are movement based. Common motor tics are eye blinking, eye darting, facial movements and head/neck/shoulder movements. Vocal tics are sound based. Common vocal tics include throat clearing, coughing, sniffing, grunting and humming.
Evaluation includes a detailed history where the movements or sounds are classified. Depending on the patient’s age and duration of symptoms, one can arrive to the diagnosis of Tourette’s. Different management strategies are discussed.
