Abstract
BACKGROUND Antipsychotic-associated movement disorders remain common and disabling. Their screening and assessment are challenging due to clinical heterogeneity and different use of nomenclature between psychiatrists and neurologists. OBJECTIVE An International Parkinson and Movement Disorder Society subcommittee aimed to rate psychometric quality of severity and screening instruments for antipsychotic-associated movement disorders. METHODS Following the methodology adopted by previous International Parkinson and Movement Disorders Society subcommittee papers, instruments for antipsychotic-associated movement disorders were reviewed, applying a classification as "recommended," "recommended with caveats," "suggested," or "listed." RESULTS Our review identified 23 instruments. The highest grade of recommendation reached is "recommended with caveats," assigned to seven severity rating instruments (Extrapyramidal Symptoms Rating Scale, Barnes Akathisia Rating Scale, Abnormal Involuntary Movements Scale, Drug-Induced Extra-Pyramidal Symptoms Scale, Maryland Psychiatric Research Centre involuntary movements scale, Simpson Angus Scale, and Matson Evaluation of Drug Side effects). Only three of these seven (Drug-Induced Extra-Pyramidal Symptoms Scale, Maryland Psychiatric Research Centre, Matson Evaluation of Drug Side effects) were also screening instruments. Their main caveats are insufficient demonstration of psychometric properties (internal consistency, skewing, responsiveness to change) and long duration of administration. Eight "suggested" instruments did not meet requirements for the "recommended" grade also because of insufficient psychometric validation. Other limitations shared by several instruments are lack of comprehensiveness in assessing the spectrum of antipsychotic-associated movement disorders and ambiguous nomenclature. CONCLUSIONS The high number of instruments "recommended with caveats" does not support the need for developing new instruments for antipsychotic-associated movement disorders. However, addressing the caveats with new psychometric studies and revising existing instruments to improve the clarity of their nomenclature are recommended next steps. © 2023 International Parkinson and Movement Disorder Society.

[PMID: 37037347 DOI: 10.1016/j.jamda.2023.03.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Revised: 03/04/2023] [Accepted: 03/06/2023] [Indexed: 04/12/2023]
Abstract
OBJECTIVES To evaluate properties of psychotropic adverse drug event (ADE) monitoring tools intended for use in long-term care facilities. DESIGN Systematic review. SETTING AND PARTICIPANTS Adults aged 18 years and older in nursing homes and other long-term care facilities. METHODS Medline, CINAHL, Embase, and PsycInfo were searched from inception to August 2022 for studies reporting the development, validation, or application of tools to monitor psychotropic ADEs. Screening, data extraction, and quality assessment were performed independently by 2 authors. Each tool was assessed under the domains of test-retest reliability, interrater reliability, content validity, and construct validity. RESULTS Eight studies that described 6 tools were included. Tools were developed in Wales (n = 2), United States (n = 1), Ireland (n = 1), Canada (n = 1), and Singapore (n = 1). Tools monitored 4 to 95 items related to antipsychotics (n = 6 tools), antidepressants (n = 4), benzodiazepines or hypnotics (n = 4), antiepileptics (n = 4), and dementia medications (n = 1). Tools commonly monitored sedation, tiredness, or sleepiness (n = 6); falls (n = 4); and tremor or extrapyramidal symptoms (n = 4). Tools were designed for application by nurses (n = 4), during family conferences (n = 1), and by general medical practitioners before repeat prescribing (n = 1). Two tools were reported to require 10 to 60 minutes to administer. Four tools were determined to have adequate content validity and 2 tools adequate interrater reliability. No tools reported test-retest reliability or construct validity. CONCLUSIONS AND IMPLICATIONS Six published psychotropic ADE monitoring tools are heterogeneous in design and intended application. Existing tools are predominately designed for application by nurses with or without direct involvement of the wider multidisciplinary team. Further research is needed into models of care that facilitate psychotropic ADE monitoring in the long-term care facility setting, and the extent to which application of specific tools is associated with reduced medication-related harm.

Antipsychotic dose reduction compared to dose continuation for people with schizophrenia. Cochrane Database Syst Rev 2022; 11:CD014384.

Abstract
BACKGROUND Antipsychotic drugs are the mainstay treatment for schizophrenia, yet they are associated with diverse and potentially dose-related side effects which can reduce quality of life. For this reason, the lowest possible doses of antipsychotics are generally recommended, but higher doses are often used in clinical practice. It is still unclear if and how antipsychotic doses could be reduced safely in order to minimise the adverse-effect burden without increasing the risk of relapse. OBJECTIVES To assess the efficacy and safety of reducing antipsychotic dose compared to continuing the current dose for people with schizophrenia. SEARCH METHODS We conducted a systematic search on 10 February 2021 at the Cochrane Schizophrenia Group's Study-Based Register of Trials, which is based on CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO, PubMed, ClinicalTrials.gov, ISRCTN, and WHO ICTRP. We also inspected the reference lists of included studies and previous reviews. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing any dose reduction against continuation in people with schizophrenia or related disorders who were stabilised on their current antipsychotic treatment. DATA COLLECTION AND ANALYSIS: At least two review authors independently screened relevant records for inclusion, extracted data from eligible studies, and assessed the risk of bias using RoB 2. We contacted study authors for missing data and additional information. Our primary outcomes were clinically important change in quality of life, rehospitalisations and dropouts due to adverse effects; key secondary outcomes were clinically important change in functioning, relapse, dropouts for any reason, and at least one adverse effect. We also examined scales measuring symptoms, quality of life, and functioning as well as a comprehensive list of specific adverse effects. We pooled outcomes at the endpoint preferably closest to one year. We evaluated the certainty of the evidence using the GRADE approach. MAIN RESULTS We included 25 RCTs, of which 22 studies provided data with 2635 participants (average age 38.4 years old). The median study sample size was 60 participants (ranging from 18 to 466 participants) and length was 37 weeks (ranging from 12 weeks to 2 years). There were variations in the dose reduction strategies in terms of speed of reduction (i.e. gradual in about half of the studies (within 2 to 16 weeks) and abrupt in the other half), and in terms of degree of reduction (i.e. median planned reduction of 66% of the dose up to complete withdrawal in three studies). We assessed risk of bias across outcomes predominantly as some concerns or high risk. No study reported data on the number of participants with a clinically important change in quality of life or functioning, and only eight studies reported continuous data on scales measuring quality of life or functioning. There was no difference between dose reduction and continuation on scales measuring quality of life (standardised mean difference (SMD) -0.01, 95% confidence interval (CI) -0.17 to 0.15, 6 RCTs, n = 719, I2 = 0%, moderate certainty evidence) and scales measuring functioning (SMD 0.03, 95% CI -0.10 to 0.17, 6 RCTs, n = 966, I2 = 0%, high certainty evidence). Dose reduction in comparison to continuation may increase the risk of rehospitalisation based on data from eight studies with estimable effect sizes; however, the 95% CI does not exclude the possibility of no difference (risk ratio (RR) 1.53, 95% CI 0.84 to 2.81, 8 RCTs, n = 1413, I2 = 59% (moderate heterogeneity), very low certainty evidence). Similarly, dose reduction increased the risk of relapse based on data from 20 studies (RR 2.16, 95% CI 1.52 to 3.06, 20 RCTs, n = 2481, I2 = 70% (substantial heterogeneity), low certainty evidence). More participants in the dose reduction group in comparison to the continuation group left the study early due to adverse effects (RR 2.20, 95% CI 1.39 to 3.49, 6 RCTs with estimable effect sizes, n = 1079, I2 = 0%, moderate certainty evidence) and for any reason (RR 1.38, 95% CI 1.05 to 1.81, 12 RCTs, n = 1551, I2 = 48% (moderate heterogeneity), moderate certainty evidence). Lastly, there was no difference between the dose reduction and continuation groups in the number of participants with at least one adverse effect based on data from four studies with estimable effect sizes (RR 1.03, 95% CI 0.94 to 1.12, 5 RCTs, n = 998 (4 RCTs, n = 980 with estimable effect sizes), I2 = 0%, moderate certainty evidence). AUTHORS' CONCLUSIONS: This review synthesised the latest evidence on the reduction of antipsychotic doses for stable individuals with schizophrenia. There was no difference between dose reduction and continuation groups in quality of life, functioning, and number of participants with at least one adverse effect. However, there was a higher risk for relapse and dropouts, and potentially for rehospitalisations, with dose reduction. Of note, the majority of the trials focused on relapse prevention rather potential beneficial outcomes on quality of life, functioning, and adverse effects, and in some studies there was rapid and substantial reduction of doses. Further well-designed RCTs are therefore needed to provide more definitive answers.

Expanding phenomenologic heterogeneity of tardive syndromes: Time for an updated assessment tool. Parkinsonism Relat Disord 2020; 77:141-145.

Abstract
Tardive syndromes (TDS) are a group of hyperkinetic and hypokinetic movement disorders that occurs after exposure to dopamine receptor blocking agents such as antipsychotic and antiemetic drugs. The Abnormal Involuntary Movement Scale (AIMS) is a widely used instrument that has become the standard for assessment of tardive dyskinesia (TDD), the most common form of TDS. However, the AIMS has a number of clinimetric limitations and was designed primarily to assess the anatomic distribution and severity of involuntary movements without regard to phenomenology. To build on recent advances in understanding and treatment of TDS, re-evaluation and revision of the AIMS that could aid both clinical practice and research may be worthwhile. Challenges, such as retaining the efficiency of the current AIMS, incorporating evaluation of impairment in daily activities, and re-training clinicians for a revised examination procedure and rating instrument, are very likely surmountable.

Abstract
OBJECTIVE The purpose of this study is to develop an index to measure oral and maxillofacial frailty in older adults as an acceptable screening tool. METHODS Three hundred adults (aged ≥ 50 years) participated in this study by telephone interview. Ten candidate items for the Oral and Maxillofacial Frailty Index (OMFI) and 20 matched detailed items for oral and maxillofacial functions were asked. Information about sociodemographic and oral health-related variables was also obtained. The test-retest reliability of the 10 candidate items was determined. Correlations of the 10 candidate items with the 20 detailed items or sociodemographic and oral health-related variables were analysed to test the validity of the candidate items. To suggest optimal items for the OMFI, five different models with different numbers of items were constructed and evaluated based on their associations with main variables. RESULTS The overall internal consistency of the 10 candidate items was .704, and the Cronbach's alpha value of each item was .23-.55. The test-retest reliability was excellent. There were significant correlations between the 10 candidate and 20 matched detailed items. The score of the 10 candidate items was significantly different according to gender, education level and oral health-related variables. The final five items for the OMFI were difficulties in chewing, the necessity of water when eating dry food, difficulties in jaw or tongue movements, difficulties in speaking or pronunciation and difficulties in facial expression. CONCLUSIONS The five items could be used as a screening tool for evaluating oral and maxillofacial frailty in older adults.

Abstract
Although VMAT2-inhibitors are now established as first-line treatment for tardive dyskinesia, not all patients respond to, or tolerate them. Numerous other agents have been adopted to treat tardive dyskinesia, but with variable results and generally lower quality methodologic reports. Amantadine is the most promising but benzodiazepines, branched chain neutral amino acids, Vitamin B6, several nutraceuticals, and botulinum toxin injections might help some patients. In all cases, better placebo controlled trials are needed before definitive recommendations can be made.

Abstract
Traditional efforts to delineate the clinical heterogeneity of schizophrenia have been unsuccessful because of the absence of a valid, stable, and meaningful subtyping scheme. A clinically-informed nosology supported by multivariate statistical classification methods may provide a better approach for classifying schizophrenia. The goals of the current study were to 1) use multivariate classification methods to validate a clinical subtyping scheme based on the profile of negative symptoms; and 2) following validation to contrast the statistically-derived subgroups to ascertain distinguishing demographic, clinical, cognitive, and functional characteristics. In the current study, 706 people with schizophrenia completed measures of positive and negative symptoms, premorbid adjustment, cognition, and psychosocial functioning. Latent class analysis served to identify the number of negative symptom subgroups in schizophrenia. Next, statistical classification methods-Bayes Theorem and the Base Rate Classification Technique-were used to assign participants into the identified subgroups. Subgroups were compared on external validation variables not used in the classification process via logistic regression and discriminant function analysis. Latent class analysis supported a three-class model of schizophrenia that included deficit, persistent, and transient negative symptom subgroups. Posthoc comparisons showed that demographic characteristics, positive symptoms, premorbid adjustment, and cognitive profiles can distinguish the schizophrenia subgroups with moderate accuracy. The deficit subgroup had the greatest impairments in psychosocial functioning and quality of life variables. Findings suggest that schizophrenia encapsulates qualitatively distinct negative symptom subgroups that differ in their demographic, symptomatic, neuropsychological, and functional profiles. Schizophrenia heterogeneity reflects a combination of non-arbitrary subgroups and severity-based differences in negative symptoms.

Abstract
OBJECTIVES To propose the application of the concept of geriatric syndrome for common geriatric oral and maxillofacial dysfunctions and to suggest the necessity of developing effective evaluation methods for oral and maxillofacial frailty. DESIGN The concepts of frailty and geriatric syndrome based on multi-morbidity and polypharmacy were applied to five common geriatric oral medicinal dysfunctional problems: salivary gland hypofunction (dry mouth), chronic oral mucosal pain disorders (burning mouth symptoms), taste disorders (taste disturbances), swallowing disorders (dysphagia), and oral and maxillofacial movement disorders (oromandibular dyskinesia and dystonia). RESULTS Each of the dysfunctions is caused by various kinds of diseases and/or conditions and medications, thus the concept of geriatric syndrome could be applied. These dysfunctions, suggested as components of oral and maxillofacial geriatric syndrome, are associated and interacted with each other in a complexity of vicious cycle. The resulting functional impairments caused by this syndrome can cause oral and maxillofacial frailty. CONCLUSIONS Geriatric oral and maxillofacial dysfunctions could be better appreciated in the context of geriatric syndrome. The development of effective methods for evaluating the severity of these dysfunctions and the resulting frailty is essential.

Abstract
OBJECTIVE The aim of this systematic review was to critically appraise the psychometric properties of antipsychotic medication side effect assessment tools. METHODS Systematic searches were undertaken in PubMed, CINAHL and CENTRAL from inception to October 2014. Studies were included if they detailed the evaluation of psychometric properties of antipsychotic medication side effect assessment tools in mental health populations. Studies were excluded if they examined the use of antipsychotic medication side effect assessment tools in non-mental health populations, including people suffering from dementia, Parkinsonism and Alzheimer's. Narrative reviews and studies published in any language other than English were also excluded. RESULTS Content validity was appropriately established for only one of the tools, reliability was inappropriately evaluated for all but one tool, and the assessment of responsiveness was not acceptable for any tool. CONCLUSION Further psychometric studies are warranted to consolidate the psychometric properties of the included antipsychotic medication side effect assessment tools before any of these tools can be confidently recommended for either research or clinical purposes.

Abstract
OBJECTIVE The aim of this study was to evaluate demographic, clinical, and treatment factors that may impact on neurological adverse effects in naive and quasi-naive children and adolescents treated with antipsychotics. METHODS This was a 1-year, multicenter, observational study of a naive and quasi-naive pediatric population receiving antipsychotic treatment. Two subanalyses were run using the subsample of subjects taking the 3 most used antipsychotics and the subsample of antipsychotic-naive subjects. Total dyskinesia score (DyskinesiaS) and total Parkinson score (ParkinsonS) were calculated from the Maryland Psychiatric Research Center Involuntary Movement Scale, total UKU-Cognition score was calculated from the UKU Side Effect Rating Scale. Risk factors for tardive dyskinesias (TDs) defined after Schooler-Kaine criteria were studied using a logistic regression. RESULTS Two hundred sixty-five subjects (mean age, 14.4 [SD, 2.9] years) with different Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Axis I disorders were recruited. DyskinesiaS (P < 0.001) and ParkinsonS (P < 0.001) increased at 1-year follow-up. Risperidone was associated with higher increases in DyskinesiaS compared with quetiapine (P < 0.001). Higher increases in ParkinsonS were found with risperidone (P < 0.001) and olanzapine (P = 0.02) compared with quetiapine. Total UKU-Cognition Score decreased at follow-up. Findings were also significant when analyzing antipsychotic-naive subjects. Fifteen subjects (5.8%) fulfilled Schooler-Kane criteria for TD at follow-up. Younger age, history of psychotic symptoms, and higher cumulative exposure time were associated with TD at follow-up. CONCLUSIONS Antipsychotics increased neurological adverse effects in a naive and quasi-naive pediatric population and should be carefully monitored. Risperidone presented higher scores in symptoms of dyskinesia and parkinsonism. Quetiapine was the antipsychotic with less neurological adverse effects. Younger subjects, psychosis, and treatment factors predicted an increased risk of TD.

Abstract
INTRODUCTION Many patients experience side effects during treatment with antipsychotics. This article reviews the clinical use and psychometric characteristics of rating scales used to assess side effects in patients treated with antipsychotics. METHODS A systematic literature search was performed using the electronic databases PubMed and Embase, with predefined search terms. RESULTS In total, 52 different scales were used in the 440 articles retrieved. For multiple side effects measured with one scale, the Udvalg for Kliniske Undersøgelser Side Effects Rating Scale for Clinicians was used the most, whereas the Liverpool University Neuroleptic Side Effect Rating Scale had the best psychometric characteristics (Cronbach's α 0.81 and test-retest reliability 0.89). The Simpson Angus Scale was used the most to rate extrapyramidal side effects, although the Maryland Psychiatric Research Center scale had the best characteristics (Cronbach's α 0.80, test-retest reliability 0.92 and inter-rater reliability 0.81-0.90). The Arizona Sexual Experience Scale was used the most to assess sexual dysfunction, but the Antipsychotics and Sexual Functioning Questionnaire and the Nagoya Sexual Functioning Questionnaire had the best characteristics. CONCLUSION This review will help researchers and clinicians make a purpose-oriented choice of which scale to use. SYSTEMATIC REVIEW REGISTRATION NUMBER CRD42014013010.

Abstract
BACKGROUND Intramuscular injections (depot preparations) offer an advantage over oral medication for treating schizophrenia by reducing poor compliance. The benefits gained by long-acting preparations, however, may be offset by a higher incidence of adverse effects. OBJECTIVES To assess the effects of fluphenazine decanoate and enanthate versus oral anti-psychotics and other depot neuroleptic preparations for individuals with schizophrenia in terms of clinical, social and economic outcomes. SEARCH METHODS We searched the Cochrane Schizophrenia Group's Trials Register (February 2011 and October 16, 2013), which is based on regular searches of CINAHL, BIOSIS, AMED, EMBASE, PubMed, MEDLINE, PsycINFO, and registries of clinical trials. SELECTION CRITERIA We considered all relevant randomised controlled trials (RCTs) focusing on people with schizophrenia comparing fluphenazine decanoate or enanthate with placebo or oral anti-psychotics or other depot preparations. DATA COLLECTION AND ANALYSIS We reliably selected, assessed the quality, and extracted data of the included studies. For dichotomous data, we estimated risk ratio (RR) with 95% confidence intervals (CI). Analysis was by intention-to-treat. We used the mean difference (MD) for normal continuous data. We excluded continuous data if loss to follow-up was greater than 50%. Tests of heterogeneity and for publication bias were undertaken. We used a fixed-effect model for all analyses unless there was high heterogeneity. For this update. we assessed risk of bias of included studies and used the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach to create a 'Summary of findings' table. MAIN RESULTS This review now includes 73 randomised studies, with 4870 participants. Overall, the quality of the evidence is low to very low.Compared with placebo, use of fluphenazine decanoate does not result in any significant differences in death, nor does it reduce relapse over six months to one year, but one longer-term study found that relapse was significantly reduced in the fluphenazine arm (n = 54, 1 RCT, RR 0.35, CI 0.19 to 0.64, very low quality evidence). A very similar number of people left the medium-term studies (six months to one year) early in the fluphenazine decanoate (24%) and placebo (19%) groups, however, a two-year study significantly favoured fluphenazine decanoate (n = 54, 1 RCT, RR 0.47, CI 0.23 to 0.96, very low quality evidence). No significant differences were found in mental state measured on the Brief Psychiatric Rating Scale (BPRS) or in extrapyramidal adverse effects, although these outcomes were only reported in one small study each. No study comparing fluphenazine decanoate with placebo reported clinically significant changes in global state or hospital admissions.Fluphenazine decanoate does not reduce relapse more than oral neuroleptics in the medium term (n = 419, 6 RCTs, RR 1.46 CI 0.75 to 2.83, very low quality evidence). A small study found no difference in clinically significant changes in global state. No difference in the number of participants leaving the study early was found between fluphenazine decanoate (17%) and oral neuroleptics (18%), and no significant differences were found in mental state measured on the BPRS. Extrapyramidal adverse effects were significantly less for people receiving fluphenazine decanoate compared with oral neuroleptics (n = 259, 3 RCTs, RR 0.47 CI 0.24 to 0.91, very low quality evidence). No study comparing fluphenazine decanoate with oral neuroleptics reported death or hospital admissions.No significant difference in relapse rates in the medium term between fluphenazine decanoate and fluphenazine enanthate was found (n = 49, 1 RCT, RR 2.43, CI 0.71 to 8.32, very low quality evidence), immediate- and short-term studies were also equivocal. One small study reported the number of participants leaving the study early (29% versus 12%) and mental state measured on the BPRS and found no significant difference for either outcome. No significant difference was found in extrapyramidal adverse effects between fluphenazine decanoate and fluphenazine enanthate. No study comparing fluphenazine decanoate with fluphenazine enanthate reported death, clinically significant changes in global state or hospital admissions. AUTHORS' CONCLUSIONS There are more data for fluphenazine decanoate than for the enanthate ester. Both are effective antipsychotic preparations. Fluphenazine decanoate produced fewer movement disorder effects than other oral antipsychotics but data were of low quality, and overall, adverse effect data were equivocal. In the context of trials, there is little advantage of these depots over oral medications in terms of compliance but this is unlikely to be applicable to everyday clinical practice.

Abstract
The 2003 Schizophrenia Patient Outcomes Research Team (PORT) treatment recommendations and the Mount Sinai Conference Safety Monitoring recommendations generated guidelines for pharmacological treatment of schizophrenia and monitoring of antipsychotic side effects. This study examined rate of recommendation adherence and impact of adherence on outcomes of outpatients with schizophrenia or schizoaffective disorder in community mental health centers. Clinical practice was assessed as conformant, nonconformant, or not applicable. Treatment practices were conformant for antipsychotic dose (83%); use of antiparkinsonian (97%), antidepressant (100%), and antianxiety agents (90%) but not clozapine for residual positive symptoms (31%); and monitoring weight gain (48%), glucose dysregulation (53%), hyperlipidemia (34%), or extrapyramidal symptoms (11%). Community mental health center treatment practices were largely conformant with the 2003 Schizophrenia PORT treatment recommendations. There is less evidence that patients who receive treatment in the community are adequately monitored for antipsychotic side effects per the Mount Sinai recommendations.

Abstract
BACKGROUND Previous studies indicate that negative symptoms reflect a separable domain of pathology from other symptoms of schizophrenia. However, it is currently unclear whether negative symptoms themselves are multi-faceted, and whether sub-groups of patients who display unique negative symptom profiles can be identified. METHODS A data-driven approach was used to examine the heterogeneity of negative symptom presentations in two samples: Study 1 included 199 individuals with schizophrenia assessed with a standard measure of negative symptoms and Study 2 included 169 individuals meeting criteria for deficit schizophrenia (i.e., primary and enduring negative symptoms) assessed with a specialized measure of deficit symptoms. Cluster analysis was used to determine whether different groups of patients with distinct negative symptoms profiles could be identified. RESULTS Across both studies, we found evidence for two distinctive negative symptom sub-groups: one group with predominantly Avolition-Apathy (AA) symptoms and another with a predominantly Diminished Expression (DE) profile. Follow-up discriminant function analyses confirmed the validity of these groups. AA and DE negative symptom sub-groups significantly differed on clinically relevant external validators, including measures of functional outcome, premorbid adjustment, clinical course, disorganized symptoms, social cognition, sex, and ethnicity. CONCLUSIONS These results suggest that distinct subgroups of patients with elevated AA or DE can be identified within the broader diagnosis of schizophrenia and that these subgroups show clinically meaningful differences in presentation. Additionally, AA tends to be associated with poorer outcomes than DE, suggesting that it may be a more severe aspect of psychopathology.

Abstract
BACKGROUND Emerging data indicate the neuromodulator adenosine may play a role in the therapeutics of schizophrenia. Adenosine A(2A) receptor stimulation exerts a functional antagonism at postsynaptic D(2) receptors. Data from animal models relevant to schizophrenia support a therapeutic effect of modulating adenosinergic transmission in the ventral striatum. One previous clinical trial showed superiority of adjunctive dipyridamole, an adenosine reuptake inhibitor, compared to placebo in ameliorating positive symptoms in schizophrenia patients. OBJECTIVES The aim of this study was to examine the effects of dipyridamole monotherapy of 200 mg/day on positive and negative symptoms, with the goal of determining dosing for future adjunctive studies in schizophrenia. METHODS Twenty symptomatic schizophrenia participants were randomized to a 6-week double-blind trial comparing olanzapine (20 mg/day) to dipyridamole monotherapy (200 mg/day). Thirteen participants completed the treatment phase (eight on dipyridamole; five on olanzapine). RESULTS The olanzapine group showed a trend (p = 0.08) for superiority on BPRS total scores (mean ± SD: total BPRS score decreasing from 36.8 ± 2.3 at week 1, to 33.2 ± 5.5 at the end of the study). The mean total BPRS scores decreased from 36.4 ± 5.3 to 34.0 ± 7.7 in the dipyridamole group. CONCLUSIONS Although these pilot data do not support a significant antipsychotic effect of dipyridamole monotherapy, the results provide some evidence for examining dipyridamole (200 mg/day) as adjunct to symptomatic antipsychotic-treated schizophrenia patients.

Abstract
OBJECTIVE Drug-induced parkinsonism (DIP) is one of the most common adverse effects of antipsychotic agents. The limited agreement about which rating scale should be used in clinical practice to assess DIP prompted us to review the feasibility and the psychometric qualities of the available instruments. METHODS The PubMed and EMBASE databases were searched in November 2008 using the terms "parkinsonism," "scale," and "drug induced" to identify instruments used to measure DIP. Then, the literature was searched for studies investigating the use and psychometric properties of each identified instrument. Outcome measures included feasibility, validity (including appropriateness of used reference test), and reliability (internal consistency and interrater and intrarater reliability). RESULTS Seventeen rating scales were identified, each with a different representation of the concept of parkinsonism. The Simpson Angus Scale (SAS) was used the most, followed by the Extrapyramidal Symptom Rating Scale. There were limited psychometric data, especially regarding validity, available for any scale. The SAS, the Drug-Induced Extrapyramidal Scale, and the parkinsonism subscale of the Schedule for the Assessment of Drug-Induced Movement Disorders, which is identical to the St Hans Rating Scale for Extrapyramidal Syndromes, seemed to have moderate to good reliability and acceptable validity. The time-consuming nature of the Schedule for the Assessment of Drug-Induced Movement Disorders would make it less useful in daily practice. CONCLUSIONS Although various scales are used to assess DIP, few have been evaluated for validity and reliability. The SAS, St Hans Rating Scale for Extrapyramidal Syndromes, and Drug-Induced Extrapyramidal Scale seem to be the most valid, reliable, and easy-to-use instruments to evaluate DIP in clinical practice.

Abstract
The concepts of partial recovery and remission have become increasingly important for the evaluation of the effectiveness of schizophrenia therapeutics. The relationship of baseline symptoms and changes in symptoms to remission of psychosis was evaluated. Fifty-six outpatients with residual schizophrenia completed a double-blind trial of olanzapine versus haloperidol and were then enrolled into a one-year open-label trial of olanzapine. Out of these 56 subjects, 13 (23%) met remission criteria at the beginning of the open-label treatment and were excluded. During the one-year study, 7/43 (16%) subjects met remission criteria. These subjects had significantly lower baseline ratings for tardive dyskinesia (TD) than subjects who did not achieve remission (1.8 +/- 1.5 vs. 4.2 +/- 4.6, P = 0.03). As expected, remitted subjects had significantly greater improvements in Brief Psychiatric Rating Scale total scores, positive subscale scores and scale for the Assessment of Negative Symptoms total scores. Remitted subjects also experienced a significantly greater improvement in depressive symptoms (P = 0.001), activation (P = 0.005), and Clinical Global Impressions scores (P < 0.001), as well as greater improvements in extrapyramidal symptoms (P = 0.007) and TD (P < 0.001). These results suggest that the relationship of depressive symptoms and improved side effects to the construct of remission in schizophrenia may deserve special attention. Future studies should aim to relate remission criteria to functional outcomes, cognition, and other important symptom domains.

Abstract
There has been a remarkable increase in prescription rates of antipsychotics in children and adolescents in recent years. Their side effects are a neglected area of research in this population, despite its vulnerability. In this cross-sectional study, we compared the presence of side effects in 60 children and adolescents who had taken antipsychotic medication for less than 1 month and 66 who had been receiving treatment with antipsychotics for more than 12 months. Mean age for the total sample was 15.62 years (SD 1.85). Groups did not differ in age, gender, or diagnosis. A total of 21.7% of short-term treatment group patients and 37.9% of longer-term treatment group patients presented mild dyskinetic movements (p = 0.004). Hyperprolactinemia was present in 78.6% and 48.5% in the short-term and longer-term treatment groups, respectively. Body mass index (p < 0.001), cholesterol levels (p < 0.001), and low-density lipoprotein-cholesterol (LDL-C) (p = 0.018) were higher in the longer-term treatment group. The use of these drugs in these populations merits careful scrutiny.

Abstract
Recent years have witnessed increased antipsychotic treatment of children despite limited long-term safety data in children. In this study, motor side effects associated with the use of antipsychotic drugs in children were examined in a sample of pediatric psychiatric patients. Child and adolescent psychiatric patients receiving antipsychotics (most were on atypicals) for 6 months or longer (n = 118) were compared with antipsychotic-naïve patients (n = 80) with similar age, sex ratio, and diagnoses. Only 19% of patients on antipsychotics had ever experienced psychotic symptoms. Eleven children (9%) on antipsychotics exhibited dyskinesia, when compared with 0 in the naïve group (P = 0.003, Fisher's exact test). Nine of 62 African-American children (15%) on antipsychotics exhibited dyskinesia, when compared with only 4% (2 of 52) of European-American children (P = 0.003, Fisher's exact test). Children treated with antipsychotic drugs might experience a significant risk of dyskinesia even when treated only with atypical antipsychotics. Ethnicity might also be a risk factor for dyskinesia in children. Side-effect profile of the atypical antipsychotic drugs in children may be much different than that in adults.

Abstract
BACKGROUND Although newly emergent tardive dyskinesia (TD) is less of a concern, about one-fourth to one-third of patients on or previously on chronic first-generation antipsychotic agents have TD. The long-term course and outcome, as well as their predictors, are unknown. Earlier studies identify ethnicity as one of the risk factors for the development of TD, and case reports have noted a preponderance of African-American males in cohorts of patients with tardive dystonia. The current study examines the anatomic distribution and course of TD in a cohort of schizophrenia patients of European and African descent with TD who were referred to the Motor Disorders Clinic (MDC). METHODS We evaluated data collected on 1149 TD patients who were given a focused neurologic examination for movement disorders. Movements were evaluated with the MPRC Scale for Involuntary Movements (IMS). All patients met RDC-TD criteria for diagnosis of persistent TD. One to 10-year follow-up data on 528 patients were evaluated to examine the course of TD following recommendations made to referring primary clinicians. Suggested interventions to referring primary clinicians included dose reduction of first-generation antipsychotic medication, or switching to a second-generation antipsychotic. RESULTS Initial evaluation included 701 European American (EA) patients and 448 African-American (AA) patients. AA patients had a significantly higher proportion of males [chi(1) = 7.50, P < 0.05]. EA subjects had a higher mean age than AA patients 42.8 +/- 11.2 and 39.8 +/- 10.4, respectively [F(1,1147) = 22.27, P < 0.05]. Mean neuroleptic exposure (chlorpromazine equivalents) was similar in both groups after controlling for differences in age.Follow-up data analyzed in 528 patients (329 EA and 199AA) showed a significant ethnicity by TD interaction [F(1,504) = 4.26, P < 0.05]. Examination of body distribution of dyskinetic movements showed an effect of ethnicity. Subsequent analyses suggest EA patients experienced more improvement in TD over the course of follow up [F(1,319) = 22.39, P < 0.05] compared with AAs [F(1,189) = 1.58, P > 0.05]. These findings were unchanged when age, change in antipsychotic drug dose, and duration of follow-up were covaried. CONCLUSION Reports from earlier studies note ethnicity (African descent) as a risk factor in the development of TD. Our study findings suggest ethnicity might be an important factor in predicting a poor course of TD.

Abstract
OBJECTIVE Treatment of dyskinetic disorders, in general, and of tardive dyskinesia (TD), in particular, is difficult. The opiate peptide enkephalin coexits with gamma aminobutyric acid in the projection neurons of striatum forming the "indirect" pathway. Several lines of preclinical evidence implicate this enkephalin-comediated pathway in the pathophysiology and therapeutics of dyskinesia. However, previous studies, most using relatively low doses of opioid antagonists, showed mixed results. The goal of the current study was to test whether moderately high doses of naltrexone, alone or in combination with a subtherapeutic dose of a gamma aminobutyric acid agonist, improve TD. METHODS In 2 double-blind, placebo-controlled, randomized, crossover trials, effects of naltrexone alone (n = 9) and in combination with clonazepam (n = 14) were tested on TD. In both trials, patients' antipsychotic medication and dose remained unchanged through the trial. Naltrexone dose was increased over a period of 3 weeks to 200 mg/d and maintained at that dose for another week. In the second study, patients were first stabilized on low dose (0.25 to 0.5 mg) of clonazepam for 4 weeks or longer. In addition to the TD scores, saccadic peak velocity and latency, as measures of vigilance, and antisaccade error rate were obtained during the fourth week of placebo and naltrexone in a subgroup of patients. RESULTS There were no significant effects of naltrexone alone on TD (mean +/- SD decrease in TD score = 0.1 +/- 4.8), psychosis scores, or eye movement measures. Low dose of clonazepam had no effect on TD. However, addition of naltrexone significantly improved TD (mean, SD decrease in TD score 4.0 +/- 3.6). There was no clinical or laboratory evidence of increased sedation during treatment with naltrexone compared to placebo. There were no significant effects on the antisaccade error rate or psychosis scores. CONCLUSION These findings suggest effectiveness of a strategy of combining a GABA(gamma aminobutyric acid)mimetic drug with an enkephalin antagonist to treat dyskinesia.

Abstract
The metric properties of the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS) were examined in 182 subjects treated with antipsychotics. Inter-rater reliability, test-retest reliability, and concurrent validity with other rating scales for EPS were high. Four factors were identified and the optimal diagnostic cut-off scores were obtained. These results suggest that the DIEPSS is a reliable and valid multidimensional rating scale.

Abstract
In order to understand mechanisms underlying the smooth pursuit abnormality(ies) in schizophrenia, new methods, which independently evaluated predictive smooth pursuit responses to extra-retinal motion signals, were developed and tested. The study compared responses to only extra-retinal motion signals in normal volunteers (n = 25), and individuals with a chronic (n = 21) and a recent onset (n = 18) schizophrenia. Subject groups with chronic schizophrenia and recent onset schizophrenia had significantly poorer predictive pursuit than normal subjects in response to only extra-retinal motion signals. The poor predictive pursuit was evident even at low target velocity when the closed-loop pursuit gain was normal in patients with schizophrenia. Ten of the 18 recent onset patients were drug-free at the time of testing and had no or minimum previous exposure to anti-psychotic medications. Re-analyses of the data showed that on most measures of predictive pursuit, drug-free patients were not significantly different from patients who received anti-psychotic drug treatment. Both patient groups had significantly poorer predictive pursuit than normal subjects. These results suggest that a deficit in processing extra-retinal motion may underlie the abnormal smooth pursuit response in schizophrenia. At low target velocities, patients with schizophrenia were able to compensate for the low extra-retinal gain by increasing the gain of response to the retinal slip velocity. This indicates that patients were able to process retinal slip velocity and generate smooth pursuit eye movements, but experienced a specific deficit in processing and/or integrating extra-retinal motion information for the smooth pursuit response.

Abstract
OBJECTIVE The major purposes of this study were 1) to examine whether neurological signs predict cognitive performance in both schizophrenic patients and healthy subjects and 2) to determine the ability of neurological signs and neuropsychological tests to discriminate schizophrenic patients from healthy subjects. METHOD Eighty-five patients with a DSM-III-R diagnosis of schizophrenia and 36 normal comparison subjects were included in the study. All subjects were administered a comprehensive neuropsychological test battery, and neurological signs were assessed with the Neurological Evaluation Scale. Stepwise regression analyses were used to predict neuropsychological test performance from the subscale scores on the Neurological Evaluation Scale. Forward stepwise linear discriminant function analyses were used to examine the discriminative ability of neurological subscale scores, neuropsychological test scores, and the two combined. RESULTS Scores on the Neurological Evaluation Scale predicted the neuropsychological test performance of both patients and comparison subjects. The sensory integration subscale score was the most frequent predictor of neuropsychological test performance. In contrast, the "others" subscale, which includes frontal release signs, abnormalities in eye movements, and short-term memory, was the most highly discriminating subscale, correctly classifying 78.5% of the total study group. The best predictors from the neuropsychological battery (category fluency and Trail Making Test, part A, time test) correctly classified 81.8%. When both sets of variables were used, the Neurological Evaluation Scale "others" subscale entered the discriminant function first. CONCLUSIONS Neurological signs are reliably related to measures of neuropsychological performance and also reliably discriminate between patients and healthy subjects. However, some neurological signs may be more sensitive to the presence of schizophrenia, while others may be more predictive of neuropsychological performance.

Abstract
OBJECTIVE The purpose of this study was to determine whether lack of awareness of motor dysfunction and lack of insight into mental dysfunction are related and to evaluate the longitudinal stability of lack of awareness of abnormal movements in schizophrenia. METHOD Forty-three patients with schizophrenia and tardive dyskinesia participated in the study. The Scale of Unawareness of Mental Disorder was used to assess insight. All patients still meeting inclusion criteria after 2 years (N = 16) were reevaluated at follow-up. RESULTS Twenty (46.5%) of the 43 patients had at least moderate unawareness of their tardive dyskinesia. Awareness of tardive dyskinesia was only modestly related to two of the five dimensions of insight into mental disorder assessed. Patients with the deficit syndrome showed significantly less awareness of their tardive dyskinesia than patients without the deficit syndrome. Lack of awareness of tardive dyskinesia was stable over time. CONCLUSIONS Lack of awareness of tardive dyskinesia is a common feature in schizophrenia and is stable over time. Since patients are often unaware of dyskinesia, direct clinical examination is required to identify early tardive dyskinesia.

Abstract
OBJECTIVE Dose reduction strategies for the maintenance treatment of schizophrenia are designed to maintain the benefits of antipsychotic drug therapy while reducing risks. Previous strategies with decanoate preparations have been based on the use of lower doses per injection to achieve dose reduction; these strategies have achieved dose reduction but have resulted in some increase in symptoms. The authors tested a new dose reduction approach: increasing the interval between injections during intramuscular decanoate antipsychotic treatment. METHOD Fifty outpatients with schizophrenia or schizoaffective disorder were randomly assigned to receive 25 mg of fluphenazine decanoate intramuscularly either every 2 weeks or every 6 weeks for 54 weeks in a double-blind design. RESULTS The two dose regimens did not differ significantly in relapse, symptom, or side effect measures. The every-6-weeks regimen was associated with a significant reduction in total antipsychotic exposure. CONCLUSIONS The use of injections every 6 weeks instead of every 2 weeks may increase compliance and improve patients' comfort as well as decrease cumulative antipsychotic exposure, without increasing relapse rates or symptoms.

Abstract
OBJECTIVE To examine the relationship between smooth pursuit eye movements and tardive dyskinesia (TD) in schizophrenia. METHODS Forty schizophrenic patients with TD and 25 non-TD patients had smooth pursuit eye movements tested with infrared oculography. In addition to the diagnosis of TD (present or absent), each patient had ratings of severity of TD. RESULTS There was no significant or strong association between TD and poor smooth pursuit eye movements. CONCLUSION The results stand in contrast to those of several previous studies, which were based on limited methodology. However, this study was not able to exclude definitively the possibility that TD is associated with poor smooth pursuit, perhaps with a small to moderate effect. Furthermore, these conclusions are limited to simple eye tracking protocols in which distractions are minimized. The question of whether or not TD is associated with poor smooth pursuit in schizophrenia needs to be resurrected.

Abstract
BACKGROUND In an ongoing effort to characterize the clinical pharmacologic profile of the partial dopamine agonist (-)-3-(3-hydroxyphenyl)-N-n-propylpiperidine [(-)-3PPP], we administered it to drug-free schizophrenic patients in two consecutive studies. METHODS In a preliminary dose-finding study, 9 patients were treated using a 6-week placebo-controlled crossover design. Then, to properly demonstrate the antipsychotic effect, we carried out an early efficacy study; here 10 patients received (-)-3PPP, 300 mg B.I.D., in a 1-week placebo-controlled crossover study. RESULTS Dose-Finding Study: (-)-3PPP showed apparent antipsychotic effect in repeated dosing, with 300 mg B.I.D. being the most effective dose for antipsychotic action; however, the apparent antipsychotic action was not sustained for longer than 1 week, presumably because of desensitization of the receptor by the agonist. Early Efficacy Study: Positive symptoms as measured by the Psychosis Change Scale decreased in 1 week by 30% with (-)-3PPP compared to placebo, and negative symptoms measured with the Brief Psychiatric Rating Scale Withdrawal subscale decreased by 28% with the drug. In both studies, (-)-3PPP lacked any evidence of motor side effects. CONCLUSIONS These data show that psychotic symptoms decrease with (-)-3PPP and suggest that the treatment of schizophrenia with partial dopamine agonist is a promising strategy. Future attention will be directed toward testing techniques to diminish the tachyphylaxis to allow an ongoing therapeutic effect.
