Tourette’s disease seems to be a harmless disorder that does not need any treatment. Tourette’s disease has no known treatment. Medications that may reduce the magnitude of repetitive movements and/or vocals are part of the treatment regimen. The most reliably effective treatments for tic reduction are neuroleptics (drugs that can be used to treat both psychiatric and non-psychotic disorders). There are a variety of neuroleptics available, but some are more effective than others (for example, haloperidol and pimozide).
Many neuroleptic side effects can be avoided by starting therapy slowly and gradually reducing the dosage as required. Sedation, weight gain, and cognitive dulling are the most frequent side effects of neuroleptics. Tremor, dystonic responses (twisting motions or postures), parkinsonian-like signs, and other dyskinetic (involuntary) movements are less frequent neurological side effects that can be easily treated by lowering the dosage.
To avoid rebound tics and withdrawal dyskinesias, it’s best to taper off neuroleptics gradually after a long period of use.
