Abstract
BACKGROUND Although antipsychotics are used to treat Tourette syndrome, there have been reports of paradoxical induction of tics by first- and second-generation antipsychotics. OBJECTIVE The objective of this systematic review was to better characterize tics as the potential adverse effect of antipsychotics. METHODS A literature search was performed, with no language restriction, using the MEDLINE, EMBASE, and PsycINFO databases for all publications up to January 2018. To be included, studies utilizing any study design had to meet the following criteria: (1) a temporal association of tics with antipsychotic use where tics emerged during treatment or after discontinuation and (2) no diagnosis of Tourette syndrome before tic emergence. More stringent criteria were used for individuals under 18 years of age that included (1) no personal or family history of primary tic disorder and either (2) tics occurring during antipsychotic treatment improved significantly upon discontinuation or dose reduction or (3) tics emerged after discontinuation of at least 3 months of antipsychotic treatment. Data were extracted according to: age, sex, diagnosis, personal history of motor symptoms or family history of tics, antipsychotic type and dose, treatment duration, types of symptoms emerged, treatment strategies, and follow-up. A Fisher's exact test was used to compare the occurrence of symptoms between first- and second-generation antipsychotic users. RESULTS The search identified 1290 articles, of which 92 full-text articles were assessed leading to the inclusion of 50 articles. Most of the included articles were case reports or series, involving a total of 60 cases. Thirty cases were associated with treatment with first-generation antipsychotics, 27 with second-generation antipsychotics, and three with a combination of first- and second-generation antipsychotics. Antipsychotics were being used to treat schizophrenia in 60% of the cases and other indications included developmental, behavioral, and mood or anxiety disorders. Tics occurred during treatment (n = 44) or following treatment discontinuation (n = 16). The occurrence of vocal tics with or without motor tics was significantly higher in the first- vs. second-generation antipsychotic users (p < 0.0001). Significantly higher occurrences were also noted in the first- vs. second-generation antipsychotic users for specific types of vocal tics (i.e., barking and coprolalia) and other concurrent motor symptoms (i.e., tardive dyskinesia). In the cases identified, antipsychotic-associated tics were treated by (1) discontinuing the offending antipsychotic, reducing its dose, or switching to different antipsychotics for tics occurring during treatment, (2) reinitiating antipsychotic treatment for tics occurring following discontinuation, or (3) using non-antipsychotic agents. It should be noted that symptoms were not always fully reversible and recurred at times. CONCLUSION Tics can be a disturbing adverse effect of antipsychotics. Clinicians need to be particularly vigilant when initiating and modifying antipsychotic regimens.

Abstract
Tics and other stereotyped abnormal movements can be seen as adverse effects of some pharmacologic drugs. Among these drugs, antipsychotics may provoke tardive syndromes after a chronic exposure, primarily in the case of typical antipsychotics. These syndromes include tardive tics, tardive dyskinesia, or tardive akathisia, which present with tics or stereotyped movements as a clinical phenomenon. Psychostimulants (mainly methylphenidate) have traditionally been associated with the appearance of tics due to the increased dopamine activity caused by stimulants. Nevertheless, in recent years, several studies have concluded not only that methylphenidate does not exacerbate or reactivate tics but also that tics can improve with its use in patients with associated attention deficit and hyperactivity disorder and tic disorder. Antiepileptic drugs, although infrequently, can also induce tics, with carbamazepine and lamotrigine described as tic inducers. Other antiepileptics, including levetiracetam and topiramate, have been proposed as a potential treatment for tic disorders due to a positive effect on tics, especially in those with associated epileptic disorder. Clinical and therapeutic approaches to tics and stereotyped movements after exposure to antipsychotics, stimulants, and antiepileptic drugs will be reviewed in this chapter.

Abstract
To develop a European guideline on pharmacologic treatment of Tourette syndrome (TS) the available literature was thoroughly screened and extensively discussed by a working group of the European Society for the Study of Tourette syndrome (ESSTS). Although there are many more studies on pharmacotherapy of TS than on behavioral treatment options, only a limited number of studies meets rigorous quality criteria. Therefore, we have devised a two-stage approach. First, we present the highest level of evidence by reporting the findings of existing Cochrane reviews in this field. Subsequently, we provide the first comprehensive overview of all reports on pharmacological treatment options for TS through a MEDLINE, PubMed, and EMBASE search for all studies that document the effect of pharmacological treatment of TS and other tic disorders between 1970 and November 2010. We present a summary of the current consensus on pharmacological treatment options for TS in Europe to guide the clinician in daily practice. This summary is, however, rather a status quo of a clinically helpful but merely low evidence guideline, mainly driven by expert experience and opinion, since rigorous experimental studies are scarce.

Abstract
In the care of children with autism spectrum disorders (ASD), medical treatment is typically considered an adjunct to educational and behavioral interventions. Nonetheless, large proportions of children with ASD are managed medically and receive both pharmacologic and complementary-alternative medicine (CAM) treatments. Although many medical treatments have been studied in children with ASD, studies vary widely in terms of the sample, sample size, research design, purposes of treatment, and measurements of change. Surprisingly, comprehensive reviews of the options for medical management in ASD are lacking, particularly reviews that address both pharmacologic and CAM treatments. Furthermore, reviews to date tend to emphasize general effects of medication; this perspective contradicts medical practice, which targets particular symptoms during treatment selection and monitoring. This review of 115 studies adds to the ASD treatment literature by (1) including studies of individuals 0 to 22 years of age; (2) aggregating studies of pharmacologic treatments and CAM treatments; and importantly, (3) organizing treatment response by ASD symptoms, differentiating core and associated symptoms.
