Abstract
AIM Phenomena within the psychosis continuum that varies in frequency/duration/intensity have been increasingly identified. Different terms describe these phenomena, however there is no standardization within the terminology. This review evaluated the definitions and assessment tools of seven terms - (i) 'psychotic experiences'; (ii) 'psychotic-like experiences'; (iii) 'psychotic-like symptoms'; (iv) 'attenuated psychotic symptoms'; (v) 'prodromal psychotic symptoms'; (vi) 'psychotic symptomatology'; and (vii) 'psychotic symptoms'. METHODS EMBASE, MEDLINE, and CINAHL were searched during February-March 2019. Inclusion criteria included 1989-2019, full text, human, and English. Papers with no explicit definition or assessment tool, duplicates, conference abstracts, systematic reviews, meta-analyses, or no access were excluded. RESULTS A total of 2238 papers were identified and of these, 627 were included. Definitions and assessment tools varied, but some trends were found. Psychotic experiences and psychotic-like experiences were transient and mild, found in the general population and those at-risk. Psychotic-like symptoms were subthreshold and among at-risk populations and non-psychotic mental disorders. Attenuated psychotic symptoms were subthreshold but associated with distress, risk, and help-seeking. Prodromal psychotic symptoms referred to the prodrome of psychotic disorders. Psychotic symptomatology included delusions and hallucinations within psychotic disorders. Psychotic symptoms was the broadest term, encompassing a range of populations but most commonly involving hallucinations, delusions, thought disorder, and disorganization. DISCUSSION A model for conceptualizing the required terms is proposed and future directions needed to advance this field of research are discussed.

Abstract
INTRODUCTION Methamphetamine associated psychosis (MAP) represents a mental disorder induced by chronic methamphetamine use in a subset of users. The prevalence of the disorder has increased in several countries in Europe and Asia where methamphetamine use has increased. MAP remains difficult to distinguish from primary psychiatric disorders, especially schizophrenia, creating complications in prescribing treatment plans to patients. DESIGN This narrative review sought to summarize difficulties related to MAP diagnosis and highlight the need for a better treatment model. Current best practices are described and potential novel therapies and future research suggested. RESULTS Results suggest that clear biological and clinical differences appear between patients presenting with MAP and schizophrenia and that there may exist distinct subgroups within MAP itself. MAP-specific treatment studies have been few and have focused on the use of antipsychotic medication. Antipsychotic treatment has been shown to alleviate the psychotic symptoms of MAP but produce debilitating adverse effects and fail to adequately address methamphetamine use in patients. CONCLUSIONS Continued identification of subgroups within the heterogenous MAP population may lead to better diagnosis, treatment, and outcomes for patients. Psychosocial therapies should be explored in addressing the cooccurring substance use and psychosis in the treatment of MAP.

Abstract
All antipsychotics, including the atypical antipsychotics (AAPs), may cause tardive dyskinesia (TD), a potentially irreversible movement disorder, the pathophysiology of which is currently unknown. The prevention and treatment of TD remain major challenges for clinicians. We conducted a PubMed search to review the prevalence and etiology of and management strategies for TD associated with AAPs. TD prevalence rates varied substantially between studies, with an estimated prevalence of around 20% in patients using AAPs. The risk of TD is lower with AAPs than with typical antipsychotics (TAPs) but remains a problem because AAPs are increasingly being prescribed. Important risk factors associated with TD include the duration of antipsychotic use, age, and ethnicity other than Caucasian. Theories about the etiology of TD include supersensitivity of the dopamine receptors and oxidative stress, but other neurotransmitters and factors are probably involved. Studies concerning the management of TD have considerable methodological limitations. Thus, recommendations for the management of TD are based on a few trials and clinical experience, and no general guidelines for the management of TD can be established. The best management strategy remains prevention. Caution is required when prescribing antipsychotics, and regular screening is needed for early detection of TD. Other strategies may include reducing the AAP dosage, switching to clozapine, or administering vesicular monoamine transporter (VMAT)-2 inhibitors. In severe cases, local injections of botulinum toxin or deep brain stimulation may be considered. More clinical trials in larger samples are needed to gather valid information on the effect of interventions targeting TD.

Abstract
Extrapyramidal adverse events (EPS) occur less frequently with second-generation antipsychotics (SGAs) than with first-generation antipsychotics (FGAs). Tardive dyskinesia (TD), but not tardive dystonia (TDt), also seems to occur less often in adults. TD was found to occur less frequently in children and adolescents treated with FGAs than in adults. No data are available on TDt, and the data pertaining to SGAs are limited and conflicting. SGAs differ in their profile of adverse events. Aripiprazole is less frequently associated with adverse metabolic or cardiac events, but more often with EPS, at least in children and adolescents. To date, there are several case reports of TD or TDt with aripiprazole in adults. Symptomatology, differential diagnosis, pathophysiology, prevalence, and therapy of TDt are presented here based on a case report of TDt during aripiprazole therapy in a 13-year-old girl. During medication with SGAs, the occurrence of EPS, including tardive movement disorders, should be considered and regularly monitored.

Abstract
Since the discovery of chlorpromazine (CPZ) in 1952, first-generation antipsychotics (FGAs) have revolutionized psychiatric care in terms of facilitating discharge from hospital and enabling large numbers of patients with severe mental illness (SMI) to be treated in the community. Second-generation antipsychotics (SGAs) ushered in a progressive shift from the paternalistic management of SMI symptoms to a patient-centered approach, which emphasized targets important to patients - psychosocial functioning, quality of life, and recovery. These drugs are no longer limited to specific Diagnostic and Statistical Manual of Mental Disorders (DSM) categories. Evidence indicates that SGAs show an improved safety and tolerability profile compared with FGAs. The incidence of treatment-emergent extrapyramidal side effects is lower, and there is less impairment of cognitive function and treatment-related negative symptoms. However, treatment with SGAs has been associated with a wide range of untoward effects, among which treatment-emergent weight gain and metabolic abnormalities are of notable concern. The present clinical review aims to summarize the safety and tolerability profile of selected FGAs and SGAs and to link treatment-related adverse effects to the pharmacodynamic profile of each drug. Evidence, predominantly derived from systematic reviews, meta-analyses, and clinical trials of the drugs amisulpride, aripiprazole, asenapine, brexpiprazole, cariprazine, clozapine, iloperidone, lurasidone, olanzapine, paliperidone, quetiapine, risperidone, sertindole, ziprasidone, CPZ, haloperidol, loxapine, and perphenazine, is summarized. In addition, the safety and tolerability profiles of antipsychotics are discussed in the context of the "behavioral toxicity" conceptual framework, which considers the longitudinal course and the clinical and therapeutic consequences of treatment-emergent side effects. In SMI, SGAs with safer metabolic profiles should ideally be prescribed first. However, alongside with safety, efficacy should also be considered on a patient-tailored basis.

Abstract
INTRODUCTION Tardive dyskinesia (TD) is an iatrogenic movement disorder most commonly observed in patients with psychotic disorders who are treated with dopamine blocking antipsychotic medications. Treatment options are limited, and recommendations for treatment are based on a relative scarcity of evidence. Areas covered: After briefly highlighting current mechanistic theories of TD, this review will discuss the evidence for a number of medications of several different classes that have been studied for the treatment of TD since the 1970s with an emphasis on placebo controlled trials when possible. We used a Pubmed search of primary studies, reviews, and metaanalyses on the topic of TD treatment in order to cover this topic. Expert opinion: Treatment of TD is difficult given limited data and incomplete understanding of the mechanism. Treatment of TD must be evaluated on an individual basis with careful weight given to severity of symptoms. We suggest the use of atypical versus conventional antipsychotics whenever possible and would recommend trials with one or more of a number of additional agents starting with valbenazine.

Abstract
INTRODUCTION The effectiveness, effective dosages and side effect profiles of antipsychotic medication differ significantly between the sexes. Areas covered: We present a systematic review of gender-differences in the treatment of psychosis focusing on randomized, controlled trials and meta-analyses. Expert opinion: Despite many years of research, the database on gender-differences affecting the pharmacotherapeutic approach to treating psychosis is insufficient. Currently, the US National Institute of Health encouraged the enrolment of female participants in federally supported phase III clinical trials to increase the data available of female patients. Emerging evidence points to a superior antipsychotic response in women, with men requiring higher dosages. In general, women metabolize drugs differently, resulting in side effects occuring more frequently when compared to men. In any case, women require electrocardiograms or bone density scans as well as diabetes and cardiovascular workups when treated with antipsychotics. Dose adjustments during the menstrual cycle (e.g. to raise antipsychotic doses premenstrually) should be considered. First-generation antipsychotics, drugs that are known to prolong QTc interval and increase prolactin levels should be avoided in postmenopausal female patients. Furthermore, the effects of antipsychotics during pregnancy and breastfeeding have been investigated insufficiently, and more research is urgently needed.

Abstract
The present report describes the cases of a 17-year-old male patient and a 13-year-old female patient who developed acute dystonia following the administration of low-dose aripiprazole (5 mg/day) after the cessation of atomoxetine treatment. Although aripiprazole-induced dystonia has been previously reported in the literature, it is rare, and most of these cases were associated with doses higher than 5 mg/day. Furthermore, both of the patients in the present study discontinued atomoxetine prior to the initiation of aripiprazole treatment; thus, this report also discussed the possible mechanisms underlying the manifestation of dystonia from the perspective of neurotransmitter activity.

Abstract
Pisa syndrome (PS) is characterized by an abnormally sustained posture with flexion of the body and head to one side and slight axial rotation of the trunk. PS has been related to the use of neuroleptics and is clinically classified as either an acute or a tardive dystonia. This is the first report describing a case of late-onset PS, occurring in a young patient treated with aripiprazole for 2 years. To establish optimal treatment management, we reviewed the literature on aripiprazole-induced PS and tardive dystonia. In light of current knowledge, we proposed a multistep algorithm to aid in the clinical management of this condition.

Abstract
L’aripiprazole peut être considéré comme un antipsychotique de 3e génération et présente théoriquement un faible risque d’induire des symptômes extrapyramidaux. Cependant, des cas de dyskinésies tardives et de dystonies induites par l’aripiprazole sont désormais rapportés assez fréquemment dans la littérature. Nous décrivons ici le cas d’un patient ayant présenté une dyskinésie d’évolution dramatique. À l’automne 2011, alors âgé de 74 ans, M X., qui n’a pas d’antécédent psychiatrique connu, présente un syndrome dépressif majeur pris en charge initialement par une association aripiprazole/escitalopram. En 2012, l’apparition progressive de dyskinésies bucco-linguo-faciales et de mouvements choréiques des membres inférieurs conduisent à l’arrêt de l’aripiprazole. Une IRM ne révèle aucune lésion des noyaux gris ou du tronc cérébral, notamment. Courant 2013 les symptômes sont amandés par l’utilisation de la tétrabénazine. Au cours de l’année suivante, on note successivement l’apparition d’une dyspnée d’effort bruyante sur spasmes diaphragmatiques, puis d’un stridor permanent sur spasme laryngé. La tétrabénazine est arrêtée en novembre 2014 dans un contexte d’aggravation de la symptomatologie dépressive. Le spasme laryngé est amélioré début 2015 par l’injection de toxine botulique, mais l’effet bénéfique s’estompe rapidement. Une nouvelle IRM réalisée en décembre 2014 ne révèle pas d’élément pour une étiologie alternative à l’hypothèse d’une dyskinésie iatrogène. En mars, la tétrabénazine est finalement réintroduite face aux dyskinésies qui persistent et deviennent de plus en plus sévères dans leur intensité. Mr X décède début juillet 2015 suite à un arrêt cardiaque dans un contexte d’insuffisance respiratoire terminale. Ce cas rappelle la prudence indispensable qu’il convient d’adopter dans l’utilisation de l’aripiprazole perçu comme un traitement antipsychotique avec un bon profil de sécurité clinique. Notre patient présentait plusieurs facteurs de risque de dyskinésie tardive incluant un âge avancé, la présence d’un trouble de l’humeur et une exposition à l’antipsychotique sur une durée supérieure à 6 mois.

Abstract
The atypical antipsychotics were believed to induce less extrapyramidal syndrome, including tardive dyskinesia (TD). Since the introduction of the quetiapine, it is also reported with less TD side effects. It even can relieve the symptoms of severe TD and reduce the risk of TD. The quetiapine's low affinity and fast dissociation from postsynaptic dopamine D2 receptors should give the least risk of producing the symptoms of TD. The quetiapine even can reduce the TD side effects related to clozapine, which has the lowest risk for TD. However, since the first case report of TD side effects related to quetiapine published on 1999, the safety of quetiapine in TD aspect has been questioned. Therefore, we want to share this case report, which was written to describe the severe late-onset TD side effects after long-term use of quetiapine in a patient with psychotic depression. The patient had no significant findings after concurrent comprehensive neurological examinations, magnetic resonance imaging of brain and electroencephalogram since the onset of TD.

Abstract
Tardive dyskinesia (TD) is a serious, often disabling, movement disorder that is caused by medications that block dopamine receptors (i.e., neuroleptics, anti-emetics). There is currently no standard treatment approach for physicians confronted with such patients. This may be the result of notions that TD is disappearing because of the switch to second-generation antipsychotic agents and that it is largely reversible. In this article we demonstrate that second-generation antipsychotics do, indeed, cause TD and, in fact, the frequency is likely higher than expected because of growing off-label uses and a tripling of prescriptions written in the last 10 years. In addition, studies demonstrate that TD actually remits in only a minority of patients when these drugs are withdrawn. Furthermore, neuroleptic agents are often utilized to treat TD, despite prolonged exposure being a risk factor for irreversibility. The outcome of these trends is a growing population afflicted with TD. We review non-neuroleptic agents that have shown positive results in small, early-phase, blinded trials, including tetrabenazine, amantadine, levetiracetam, piracetam, clonazepam, propranolol, vitamin B6, and Ginkgo biloba. Other options, such as botulinum toxin and deep brain stimulation, will also be discussed, and a suggested treatment algorithm is provided. While these agents are reasonable treatment options at this time there is a need, with a concerted effort between neurology and psychiatry, for full-scale drug development, including multicenter, randomized, blinded trials to confirm the effectiveness of the agents that were positive in phase 2 trials and the development of newer ones.

Abstract
RATIONALE Both typical and atypical antipsychotic drugs are D2 receptor antagonists but yet appear to have markedly different effects upon the induction of dopamine sensitization. OBJECTIVE This study aims to compare the effects of subchronic regimens of low-dose olanzapine and haloperidol administered to rats previously sensitized to apomorphine. METHODS Initially, rats received apomorphine (2.0 mg/kg) or vehicle treatments for five consecutive days followed by a conditioning test and an apomorphine challenge test. Next, there was an antipsychotic exposure phase in which three vehicle groups and three apomorphine groups received 10 daily injections of either vehicle, haloperidol (0.03 mg/kg) or olanzapine (0.01 mg/kg). In the final phase, all groups were given a second conditioning test and apomorphine challenge test. RESULTS Apomorphine induced sensitization and conditioning effects. Following haloperidol exposure, apomorphine conditioned and sensitization effects were potentiated but, in contrast, olanzapine exposure eliminated apomorphine sensitization effects. In addition, the sensitization induced by apomorphine transformed the low-dose haloperidol treatment into a potent locomotor stimulant treatment. In the vehicle groups, haloperidol and olanzapine exposure effects were equivalent and not different from vehicle treatment. CONCLUSIONS The profound differences observed between typical and atypical antipsychotic exposure in animals with an upregulated dopamine system are consistent with clinical evidence for lower risk of psychomotor disturbances with chronic treatment with atypical antipsychotic. Importantly, the finding that a very low dose of olanzapine reversed sensitization effects suggests that low-dose olanzapine may have clinical utility in a variety of disorders linked to sensitization of the dopamine system.

Abstract
About one third of patients with schizophrenia respond unsatisfactorily to antipsychotic treatment and are termed "treatment-resistant". Clozapine is still the gold standard in these cases. However, 40%-70% of patients do not improve sufficiently on clozapine either. In the search for more efficacious strategies for treatment-resistant schizophrenia, drugs with different pharmacological profiles seem to raise new hopes, but are they valid? The aim of this review was to evaluate the evidence for aripiprazole as a potential strategy in monotherapy or combination therapy for patients with treatment-resistant schizophrenia. The evidence for aripiprazole monotherapy and for the combination of aripiprazole with psychotropics other than clozapine is scant, and no recommendation can be made on the basis of the currently available data. More effort has been made in describing combinations of aripiprazole and clozapine. Most of the open-label and case studies as well as case reports have shown positive effects of this combination on overall psychopathology and to some extent on negative symptoms. Several reports describe the possibility of dose reduction for clozapine in combination with aripiprazole, a strategy that might help so-called "treatment-intolerant" patients. The findings of four randomized controlled trials with respect to changes in psychopathology seem less conclusive. The most commonly found beneficial effects are better metabolic outcomes and indicators of the possibility of reducing the clozapine dose. However, other side effects, such as akathisia, are repeatedly reported. Further, none of the studies report longer-term outcomes. In the absence of alternatives, polypharmacy is a common strategy in clinical practice. Combining aripiprazole with clozapine in clozapine-resistant or clozapine-intolerant patients seems to be worthy of further investigation from the pharmacological and clinical points of view.
