93,34 Possibly, the beneficial effects of clonidine on behavioral abnormalities are more pronounced than on vocal and motor tics. In general, antipsychotics seem to be more effective compared with clonidine.95 The effect of clonidine, however, shows

that noradrenergic neurotransmission is also involved in TS. Furthermore, the differentiation and characterization of subgroups may lead to different therapeutic strategies, for example, early antibiotic treatment in cases in which tics are the result of infection may help to prevent progression to chronic stages which otherwise have to be treated Inhibitors,research,lifescience,medical with neuroleptics. Therapy with immunoglobulin iv and plasmapheresis Inhibitors,research,lifescience,medical as immunomodulatory treatment strategies are currently the

objective of therapeutic trials.72 Treatment with cannabinoids, in particular 19-tetrahydrocannabinol, has shown beneficial effects in click here single cases, but a randomized, double-blind study failed to show convincing effects.96 Behavior therapy Until the introduction of haloperidol, TS was thought to be a psychogenic syndrome; psychoanalytic therapeutic concepts were very common and widely practiced. This concept totally changed during recent decades. However, supportive psychotherapy and training in coping strategies, supported by concepts of self-help care, are known to be Inhibitors,research,lifescience,medical very important, in particular in such a chronic and socially isolating disease. Although tics and other symptoms can not be influenced decisively, behavior-therapy techniques, including progressive muscle relaxation as well as learning and training of alternative behavior, Inhibitors,research,lifescience,medical can reduce the tic intensity and frequency. This technique

of habit reversal is based Inhibitors,research,lifescience,medical on the identification of tic-preceding sensations (premonitory urges).97 Experimental therapeutic approaches in TS Immunomodulatory and anti-inflammatory therapies For children with PANDAS, effective treatment with immunomodulatory substances or techniques have been described repeatedly.72 These therapies include iv immunoglobulin G (IgG) and plasmapheresis, the latter showing even better results than iv IgG. Keeping in mind the critical view of PANDAS, these Entinostat immunomodulatory therapies might also reveal favorable effects in TS patients not fulfilling PANDAS criteria. Effective IV IgG therapy has been described in TS.98 In the case of an acute or possibly also a chronic infection associated with tics, the TS symptoms including motor and vocal tics are cured by antibiotics. This has been reported for infection with Lyme-Borreliosis,66 Mycoplasma Pneumoniae,99 and streptococci.69,77 In a retrospective, open-label study in 34 TS patients, the effects and predicting variables for therapeutic effects of iv IgG versus antibiotics were evaluated.
