Abstract
Impulse control disorders in Parkinson's disease are relatively common drug-induced addictive behaviours that are usually triggered by the dopamine agonists pramipexole, ropinirole and rotigotine. This narrative review aimed to provide a comprehensive overview of the current knowledge of impulse control disorders in Parkinson's disease. We summarised the prevalence, clinical features, risk factors and potential underlying mechanisms of impulse control disorders in Parkinson's disease. Moreover, recent advances in behavioural and imaging characteristics and management strategies are discussed. Early detection as well as a tailored multidisciplinary approach, which typically includes careful adjustment of the dopaminergic therapy and the treatment of associated neuropsychiatric symptoms, are necessary. In some cases, a continuous delivery of levodopa via a pump or the dopamine D1 receptor agonist, apomorphine, can be considered. In selected patients without cognitive or speech impairment, deep brain stimulation of the subthalamic nucleus can also improve addictions. Finding the right balance of tapering dopaminergic dose (usually dopamine agonists) without worsening motor symptoms is essential for a beneficial long-term outcome.

Abstract
BACKGROUND Increasing evidence suggests an association between third-generation antipsychotics (TGAs) and impulse control disorders (ICDs). This is thought to be due to their partial agonism of dopamine receptors. However, neither the relative nor absolute risks of ICDs in those prescribed TGAs are well established. To inform clinical practice, this systematic review and meta-analysis summarizes and quantifies the current evidence for an association. METHODS An electronic search of Medline, PsychINFO, EMBASE, and the Cochrane Clinical Trials Database was undertaken from database inception to November 2022. Three reviewers screened abstracts and reviewed full texts for inclusion. A random-effects meta-analysis was conducted with eligible studies. RESULTS A total of 392 abstracts were retrieved, 214 remained after duplicates were removed. Fifteen full texts were reviewed, of which 8 were included. All 8 studies found that TGAs were associated with increased probability of ICDs. Risk of bias was high or critical in 7 of 8 studies. Three studies were included in the pooled analysis for the primary outcome, 2 with data on each of aripiprazole, cariprazine, and brexpiprazole. Exposure to TGAs versus other antipsychotics was associated with an increase in ICDs (pooled odds ratio, 5.54; 2.24-13.68). Cariprazine and brexpiprazole were significantly associated with ICDs when analyzed individually. Aripiprazole trended toward increased risk, but very wide confidence intervals included no effect. CONCLUSIONS Third-generation antipsychotics were associated with increased risk of ICDs in all studies included and pooled analysis. However, the risk of bias is high, confidence intervals are wide, and the quality of evidence is very low for all TGAs examined.

Abstract
AIMS Impulse control disorders (ICDs) are iatrogenic and idiopathic conditions with psychosocial and economic consequences for the affected individuals and their families (e.g. bankruptcy and divorce). However, the definition of ICDs has changed over time, and ICDs are not consistently included within existing taxonomies. We discuss the origins of the ICD diagnostic construct and its unsolved tensions. METHODS To contextualize the ICD diagnostic construct, we provided an overview of its origins in past centuries and followed its development across multiple editions of the Diagnostic and Statistical Manual and the International Classification of Diseases, as well as its definition within emerging ontologies. RESULTS Two independent roots of the ICD construct emerged: (a) the interest in behavioral excess as expressed in encyclopedic compilations (18th century) and (b) the juridical debate on disruptive conduct and responsibility (19th-20th centuries). These roots underlie the repeated taxonomic remodeling observed throughout the 20th and 21st centuries and three critical issues persisting in both clinical practice and research. First, the number of ICDs keeps increasing across the spectrum of human behaviors, disregarding common pathogenetic and phenomenological grounds. Secondly, ICDs substantially overlap with other mental conditions. Impulsivity is often neglected as a minor inconvenience or side effect when co-occurring with major diagnoses (e.g. depression) and therefore inadequately managed. Finally, ICDs' definitions display an unsolved tension between being conceived as hobby, moral fault or pathological drive, which may be responsible for stigma and delayed intervention. CONCLUSION The reasons that made impulse control disorders (ICDs) difficult to define from their first conceptualization are the same reasons that now complicate taxonomic efforts and diagnosis. Tracing back ICDs' roots and criticalities can help to define a common and less ambiguous theoretical framework, which may also result in the demise of the ICD construct and a move towards more clearly defined and more useful ontologies.

Abstract
BACKGROUND The dopaminergic partial agonism of the so-called third-generation antipsychotics (TGAs; aripiprazole, brexpiprazole, cariprazine) is hypothesized to cause impulse control disorders (ICDs). Relevant warnings by the Food and Drug Administration (FDA) were posted on aripiprazole (2016) and brexpiprazole (2018). Our study investigated the FDA Adverse Event Reporting System and the pharmacodynamic CHEMBL database to further characterize TGA-induced ICDs. METHODS We downloaded and pre-processed the FDA Adverse Event Reporting System up to December 2020. We adapted Bradford Hill criteria to assess each TGA's -and secondarily other antipsychotics'-causal role in inducing ICDs (pathological gambling, compulsive shopping, hyperphagia, hypersexuality), accounting for literature and disproportionality. ICD clinical features were analyzed, and their pathogenesis was investigated using receptor affinities. RESULTS A total of 2708 reports of TGA-related ICDs were found, primarily recording aripiprazole (2545 reports, 94%) among the drugs, and gambling (2018 reports, 75%) among the events. Bradford-Hill criteria displayed evidence for a causal role of each TGA consistent across subpopulations and when correcting for biases. Significant disproportionalities also emerged for lurasidone with compulsive shopping, hyperphagia, and hypersexuality, and olanzapine and ziprasidone with hyperphagia. Time to onset varied between days and years, and positive dechallenge was observed in 20% of cases. Frequently, co-reported events were economic (50%), obsessive-compulsive (44%), and emotional conditions (34%). 5-Hydroxytryptamine receptor type 1a agonism emerged as an additional plausible pathogenetic mechanism. CONCLUSIONS We detected an association between TGAs and ICDs and identified a new signal for lurasidone. ICD characteristics are behavior specific and may heavily impact on life. The role of 5-Hydroxytryptamine receptor type 1a agonism should be further explored.

Abstract
Aripiprazole has been associated with impulse control symptoms (ICS). Recently, two drugs with similar pharmacological features have become available: cariprazine and brexpiprazole. All of them interact with the D3 receptor, which plays a role in cerebral circuits involved in reward pathways. The objective of this study was to analyze whether a disproportionate number of cases of ICS are reported for cariprazine or brexpiprazole in EudraVigilance. A case/non-case study was conducted to assess the association between ICS and these antipsychotics, calculating reporting odds ratios (RORs) from their respective approval date to Nov 17, 2020. First, cases involving cariprazine or brexpiprazole were compared with those involving all other drugs. Second, to reduce the risk of confounding by indication, the RORs for cariprazine and brexpiprazole were compared with other antipsychotics. Besides, to evaluate a possible notoriety bias, a sensitivity analysis excluding aripiprazole was performed. Seven cases of ICS were reported for cariprazine and another seven for brexpiprazole. The ROR for cariprazine was 28.3 (95% confidence interval [CI], 13.4-59.8) and 33.4 (15.8-70.1) in the case of brexpiprazole. Nonetheless, this association disappeared for cariprazine when compared with other antipsychotics drugs. However, when excluding aripiprazole from the analysis, a safety signal emerged. Although our study is the first to suggest an association between cariprazine, brexpiprazole and ICS, these results should only be considered as exploratory in the context of safety signal detection. Further, well designed observational analytical studies will be needed to confirm these results.

Abstract
BACKGROUND Retrospective analyses of large databases of treated patients can provide useful links to the presence of drug misuse or rare and infrequent adverse effects, such as agranulocytosis, diabetic ketoacidosis or neuroleptic malignant syndrome. The aim of this study is to describe the adverse effects to antipsychotics reported in the Australian Database of Adverse Event Notifications (DAEN). METHODS Data were collected from the DAEN - a spontaneous reporting database. The database, which covered the period from January 2004 to December 2017, was obtained from the Therapeutic Goods Administration (TGA) website (www.TGA.gov). The drugs selected for this investigation are the following: aripiprazole, clozapine, olanzapine, paliperidone, risperidone, ziprasidone, quetiapine, haloperidol and pimozide. All data were analysed descriptively. Comparison of reporting and management of adverse events between adults (older than 20 years) and children (5-19 years) was undertaken using chi squared test, where p < 0.05 is significant. RESULTS A total of 7122 adverse events associated with the antipsychotics aripiprazole, clozapine, haloperidol, olanzapine, paliperidone, pimozide, quetiapine and risperidone were reported to the TGA between January 2004 and December 2017. On average, there were 2.6 adverse events reported for each case. The most common adverse event reported for antipsychotics was neuroleptic malignant syndrome. There were no significant differences in the number of co-medications, formulations, indications, therapeutic dose, hospital admission and overdose among the antipsychotics between paediatric and adult populations. However, there were significant differences between causality, death and the management of adverse events between adult and paediatric populations (5-19 years) (p < 0.05, chi squared test). CONCLUSION The antipsychotic drug associated with the highest adverse events in adults was clozapine, followed by olanzapine. The most common adverse event in adults, and reported with a number of antipsychotic drugs, was neuroleptic malignant syndrome. In children, the highest numbers of adverse events reported in the database were associated with risperidone, clozapine and olanzapine. PLAIN LANGUAGE SUMMARY Adverse events reported of antipsychoticsBackground: Retrospective analyses of large databases of treated patients can provide useful clues to the presence of drug misuse or rare and infrequent adverse effects associated with antipsychotics.

Abstract
BACKGROUND Aripiprazole has been linked to cases of problem gambling (PBG), but evidence supporting this association remains preliminary. Additionally, data specific to PBG in individuals with first-episode psychosis (FEP) receiving aripiprazole are limited to a few case reports, even though aripiprazole is widely used among this population that might be especially vulnerable to PBG. METHODS To examine this association, a nested case-control study was conducted in a cohort of 219 patients followed at a FEP program located in the Quebec City, Quebec, Canada, metropolitan area. Fourteen cases meeting the PBG criteria according to the Problem Gambling Severity Index were identified and matched for gender and index date to 56 control subjects. RESULTS In the univariable conditional logistic regression analysis, the use of aripiprazole was associated with an increased risk of PBG (odds ratio [OR] 15.2; 95% confidence interval [CI] 2.1-670.5). Cases were more likely to have a prior gambling history (either recreational or problematic) than controls at admittance in the program; they were also more frequently in a relationship and employed. After adjustment for age, relationship status, employment and Cluster B personality disorders, the use of aripiprazole remained associated with an increased risk of PBG (OR 8.6 [95% CI 1.5-227.2]). CONCLUSIONS Findings from this study suggest that FEP patients with a gambling history, problematic or not, may be at increased risk of developing PBG when receiving aripiprazole. They also highlight the importance of systematically screening for PBG all individuals with psychotic disorders, as this comorbidity hinders recovery. While the results also add credence to a causal association between aripiprazole and PBG, further prospective studies are needed to address some of the limitations of this present study.

Abstract
Introduction: Tourette syndrome (TS) is a neurodevelopmental disorder characterized by multiple tics which often persisting in forms of different severity throughout adult life. The prevalence of neuropsychiatric co-morbidity in patients with TS is high. Treatment of TS can involve pharmacological, behavioral, or, in rare cases, surgical therapies. Over the last two decades there has been growing interest in the use of aripiprazole, a novel partial dopamine receptor agonist, as a promising anti-tic agent.Areas covered: The authors reviewed the available literature evaluating the role of aripiprazole in the treatment of TS and other tic disorders in both children and adults. This includes data from five randomized controlled trials (RCTs) and eleven open-label studies.Expert opinion: There is moderate quality evidence supporting the use of aripiprazole in reducing tic severity in children and adolescents, however there is a lack of robust evidence evaluating its use in adults, despite expert consensus. Overall, it appears that aripiprazole is a safe and effective treatment for tics. Further large scale RCTs assessing the long-term efficacy and safety of aripiprazole in the treatment of tics are warranted, especially in adult populations with TS.

Abstract
Antipsychotic drugs are commonly prescribed, mainly for the treatment of schizophrenia and other psychotic disorders. Disproportionality analysis of pharmacovigilance data from national and international databases have been recently utilized to investigate the side-effect profiles of antipsychotics and have provided unique insights of their safety. Among several national and international spontaneous reporting databases the databases of the World Health Organization (VigiBase), of the European Medicines Agency (EudraVigilance) and the US Food and Drug Administration (FAERS) incorporate millions of Individual Case Safety Reports. The aim of our study was to systematically review published disproportionality analyses on antipsychotic drugs, in order to summarize the current state of methodology and potential strengths of this analysis while highlighting safety signal generated for these pharmacological group. PubMed was searched using a search algorithm combining terms for antipsychotic drugs and disproportionality analysis. A total of 39 articles were found to be eligible corresponding to 38 original disproportionality studies. Different measures of disproportionality were used in each study: reporting odds ratio (ROR), proportional reporting ratio (PRR), empirical Bayes geometric mean (EBGM) and the information component (IC). Despite the inherent limitations of the pharmacovigilance databases disproportionality analysis provides complemented evidence from RCTs on the safety of antipsychotics, especially regarding participants often excluded from RCTs, such as pregnant and breastfeeding women, children and participants with drug abuse, comorbidities or concomitant medications.

Abstract
BACKGROUND Pharmacovigilance studies have reported a higher risk of problematic gambling (PG) in people receiving aripiprazole (ARI), a partial dopamine agonist. This association needs to be specifically assessed in schizophrenia (SZ) given the high prevalence of risk factors for PG in this population (eg, comorbid substance use) and given the nature of the dopamine dysfunction in this disorder. At the present stage, case studies may shed light on such an association. METHODS All published cases involving SZ patients with PG while on ARI were systematically identified. Two instruments were used to assess causality. RESULTS We identified 16 published SZ cases exposed to ARI experiencing PG. Half of whom had a gambling history before ARI exposition. Naranjo scores led to the estimation of a possible link between ARI exposition and PG in 15 of 16 cases (average score of 3) and probable (score of 5) in 1 case. More than 50% of items were left unknown owing to the lack of information or scale limitations. Using the Liverpool algorithm, causality estimation was raised to probable in 13 of 16 cases, definite in 1 case, and nonassessable in 2 cases. CONCLUSIONS The present review confirms that ARI may be involved in the occurrence of PG in some SZ patients. However, important information to assess causality was frequently missing, and the 2 scales used did not yield the same degree of certainty. The current article calls for including more details in future case reports and for well-powered studies carefully assessing factors such as comorbid diagnoses.

Abstract
One of the possible long-term consequences of antipsychotic-induced hyperprolactinemia is the development of pituitary tumors - prolactinomas. So far, two pharmacovigilance studies of spontaneous adverse event report databases have suggested an increased risk, whereas a longitudinal study carried out with risperidone showed no evidence of increased risk of tumors with mass effect. Besides, information on amisulpride and paliperidone is lacking. Thus, in this study, we aimed to analyze the European pharmacovigilance database (EudraVigilance) to shed light on this issue. We searched for all suspected spontaneous cases of pituitary tumors associated with antipsychotics in EudraVigilance up to 23 March 2017. To assess the association between pituitary tumor cases and each antipsychotic, we calculated the proportional reporting ratios. Among 4 964 866 events of all types recorded in EudraVigilance, we found 292 cases of pituitary tumors associated with antipsychotics. All atypical antipsychotics except clozapine fulfilled the criteria to generate a safety signal. The highest proportional reporting ratio values were found for amisulpride 51.57 (36.3-73.2), risperidone 21.83 (18.4-25.8), and paliperidone 19.95 (14.7-27.1). Sulpiride and haloperidol showed a higher risk among typical antipsychotics 12.4 (5.89-26.1) and 7.0 (4.35-11.3). Notably, we found that a mass effect was present in 16% of the cases. Besides, 18 cases occurred in patients aged below 18 years. Our analysis of the data in EudraVigilance confirms the safety signal detected by previous studies. Interestingly, for the first time, we show that the association seems to be the strongest for amisulpride and that a mass effect was present in around 16% of the cases.

Abstract
Impulse-control problems such as gambling, increased spending, hypersexuality, and compulsive eating are thought to be influenced by temperamental, genetic, and physiological risk factors. In addition, dopamine receptor agonists have been implicated in some cases. It is postulated that aripiprazole may cause impulse-control problems because it can produce a hyperdopaminergic state in the mesolimbic pathway (reward system) through its predominant action on dopamine D3 receptors. We present the case of a patient with bipolar disorder and previous gambling behavior, in whom the gambling behavior escalated with the introduction of aripiprazole and its upward titration. The patient's gambling problems were alleviated with a decrease in aripiprazole dosage. Clinicians should be vigilant for possible gambling and other impulse-control behaviors in patients taking aripiprazole. Our literature review suggests cariprazine and brexpiprazole, which have mechanisms of action similar to that of aripiprazole, may also be associated with possible risks of impulse-control problems and pathologic gambling.

Abstract
Impulsive-compulsive spectrum disorders are associated with dopamine agonist therapy in some patients. These untoward outcomes occur with direct-acting, full and partial agonists at D2 dopamine family receptors. The disorders typically emerge during chronic treatment, and exhibit common features that are independent of the neurological or psychiatric pathology for which the initial therapy was indicated. It is well-documented that the brain is 'plastic', changing in response to alterations to internal factors (e.g., disease processes), as well as external factors (e.g., therapies). The complexities of these clinical scenarios have eluded a clear depiction of the neurobiology for impulsive-compulsive spectrum disorders and engendered considerable debate regarding the mechanistic underpinnings of the disorders. In this opinion, we use pharmacological concepts related to homeostatic compensation subsequent to chronic receptor activation to provide a unifying construct. This construct helps explain the occurrence of impulsive-compulsive spectrum disorders across disease states, and during therapy with full and partial agonists.
