Tics are sudden, repetitive, stereotyped, nonrhythmic, involuntary movements (motor tics) and utterances (phonic tics) that involve discrete muscle groups. Tics are often worse with excitement or anxiety and better during calm, focused activities. Tics are classified as either simple or complex. Simple motor tics are sudden, brief, repetitive movements that involve a limited number of muscle groups. Transient tic disorder consists of multiple motor tics, phonic tics or both, with a duration of between four weeks and twelve months. Chronic tic disorder is either single or multiple, motor or phonic tics (but not both), which are present for more than a year. Simple vocal tics may include throat-clearing, sniffing/snorting, grunting, or barking. More complex vocal tics include words or phrases. Some tics are preceded by an urge or sensation in the affected muscle group, commonly called a premonitory urge. Some with TS will describe a need to complete a tic in a certain way or a certain number of times in order to relieve the urge or decrease the sensation. Neuroleptics are the most consistently useful medications for tic suppression; a number are available but some are more effective than others (for example, haloperidol and pimozide). Specific behavioral treatments that include awareness training and competing response training, such as voluntarily moving in response to a premonitory urge, have shown effectiveness in small controlled trials.

Treatment of Tourettes Syndrome

Common Treatment of Tourettes Syndrome

Neuroleptics are the most consistently useful medications for tic suppression; a number are available but some are more effective than others (for example, haloperidol and pimozide).

Effective medications are also available to treat some of the associated neurobehavioral disorders that can occur in patients with TS.?

Stimulants currently contraindicates the use of these drugs in children with tics/TS and those with a family history of tics.

Serotonin reuptake inhibitors (clomipramine, fluoxetine, fluvoxamine, paroxetine, and sertraline) have been proven effective in some patients.?

Other medications may also be useful for reducing tic severity, but most have not been as extensively studied or shown to be as consistently useful as neuroleptics.?Additional medications with demonstrated efficacy include alpha-adrenergic agonists such as clonidine and guanfacine.

Psychotherapy may also be helpful for Tourettes Syndrome. Psychotherapy can help the person with TS better cope with the disorder and deal with the secondary social and emotional problems that sometimes occur.

Specific behavioral treatments that include awareness training and competing response training, such as voluntarily moving in response to a premonitory urge, have shown effectiveness in small controlled trials.
