Abstract
Schizophrenia is highly comorbid with obsessive-compulsive disorder (OCD); both conditions share numerous pathophysiological etiologies. We, thus, examined the risk of mental disorders in the parents of probands with schizophrenia, OCD, or both conditions. Between 2001 and 2011, we enrolled a nationwide cohort of 69,813 patients with schizophrenia, OCD, or both. The control cohort included 698,130 individuals matched for demographics. Poisson regression models were employed to examine the risk of six mental disorders in their parents, including schizophrenia, bipolar disorder, depressive disorder, OCD, alcohol use disorder, and substance use disorder. We stratified patients into schizophrenia-only, OCD-only, and dual-diagnosis groups, and the dual-diagnosis group was further divided into schizophrenia-first, OCD-first, and simultaneously diagnosed groups. Compared with controls, the schizophrenia, OCD, and dual-diagnosis groups had higher risks for the six mental disorders in their parents (range of odds ratio [OR] 1.50-7.83). The sub-analysis of the dual-diagnosis group showed that the schizophrenia-first, OCD-first, and simultaneously diagnosed groups had higher odds for schizophrenia, bipolar disorder, depressive disorder, and OCD (range of OR 1.64-6.45) in their parents than the control group; the simultaneously diagnosed and OCD-first diagnosed groups had a higher odds of parental substance use disorder, while the schizophrenia-first diagnosed group had a higher odds of parental alcohol use disorder. The interrelationship between OCD and schizophrenia is linked to bipolar disorder, depressive disorder, alcohol use disorder, and substance use disorder. The results have implications for mental health policy and future research.

Abstract
Obsessive-compulsive symptoms (OCS) are frequently observed in individuals with schizophrenia (SCZ) treated with clozapine (CLZ). This study aimed to analyze prevalence of OCS and obsessive-compulsive disorder (OCD) in this subgroup and find possible correlations with different phenotypes. Additionally, this is the first study to examine polygenetic risk scores (PRS) in individuals with SCZ and OCS. A multicenter cohort of 91 individuals with SCZ who were treated with CLZ was recruited and clinically and genetically assessed. Symptom severity was examined using the Positive and Negative Symptom Scale (PANSS), Clinical Global Impression Scale (CGI), the Calgary Depression Scale for Schizophrenia (CDSS), Global Assessment of Functioning Scale (GAF) and Yale-Brown Obsessive-Compulsive Scale (Y-BOCS). Participants were divided into subgroups based on phenotypic OCS or OCD using Y-BOCS scores. Genomic-wide data were generated, and PRS analyses were performed to evaluate the association between either phenotypic OCD or OCS severity and genotype-predicted predisposition for OCD, SCZ, cross-disorder, and CLZ/norclozapine (NorCLZ) ratio, CLZ metabolism and NorCLZ metabolism. OCS and OCD were frequent comorbidities in our sample of CLZ-treated SCZ individuals, with a prevalence of 39.6% and 27.5%, respectively. Furthermore, the Y-BOCS total score correlated positively with the duration of CLZ treatment in years (r = 0.28; p = 0.008) and the PANSS general psychopathology subscale score (r = 0.23; p = 0.028). A significant correlation was found between OCD occurrence and PRS for CLZ metabolism. We found no correlation between OCS severity and PRS for CLZ metabolism. We found no correlation for either OCD or OCS and PRS for OCD, cross-disorder, SCZ, CLZ/NorCLZ ratio or NorCLZ metabolism. Our study was able to replicate previous findings on clinical characteristics of CLZ-treated SCZ individuals. OCS is a frequent comorbidity in this cohort and is correlated with CLZ treatment duration in years and PANSS general psychopathology subscale score. We found a correlation between OCD and PRS for CLZ metabolism, which should be interpreted as incidental for now. Future research is necessary to replicate significant findings and to assess possible genetic predisposition of CLZ-treated individuals with SCZ to OCS/OCD. Limitations attributed to the small sample size or the inclusion of subjects on co-medication must be considered. If the association between OCD and PRS for CLZ metabolism can be replicated, it should be further evaluated if CYP1A2 alteration, respectively lower CLZ plasma level, is relevant for OCD development.

Abstract
OBJECTIVE Describe and compare the clinical profile of schizophrenic patients with and without obsessive-compulsive symptoms and obsessive-compulsive disorder (OCD) patients. METHODS A descriptive and analytical cross-sectional study was carried out at the psychiatry department of Hassan II University Hospital in Fez over 12 months to compare three groups of patients: "schizo-obsessive" (n=32), "schizophrenia" (n=34), and "OCD" (n=46). All participants (n=112) were assessed using the mini-international neuropsychiatric interview (MINI), the Yale-Brown obsessive-compulsive scale (Y-BOCS), the Brown assessment of beliefs scale (BABS), the Hamilton anxiety rating scale (HAM-A), the Beck's depression inventory (BDI-II), the positive and negative syndrome scale (PANSS), and the clinical global impressions-severity scale (CGI-S). RESULTS The "schizo-obsessive" group differed from the "schizophrenia" group in: more severe psychotic symptoms (mean=64.16±17.049, P<0.001), higher anxiety (mean=8.87±5,655, P<0.001) and depression (mean=7.50±5.989, P<0.001) scores, more prevalent suicide attempts (46.9%), higher illness severity score (mean=5.13±1.157, P=0.02), and more professional disinsertion (78.1%). The "schizo-obsessive" group (mean= 14.47±3.388) had significantly poor insight (P<0.001) compared to the "OCD" group (mean= 8.35±4.542). There were similarities in the obsessive and compulsive themes between the "schizo-obsessive" and the "OCD" groups, with no significant difference of severity (P=0.26). CONCLUSION A careful assessment of obsessive symptomatology is essential in schizophrenia for better patient management and prognosis.

Abstract
Almost 25% of schizophrenia patients suffer from obsessive-compulsive symptoms (OCS) considered a transdiagnostic clinical continuum. The presence of symptoms pertaining to both schizophrenia and obsessive-compulsive disorder (OCD) may complicate pharmacological treatment and could contribute to lack or poor response to the therapy. Despite the clinical relevance, no reviews have been recently published on the possible neurobiological underpinnings of this comorbidity, which is still unclear. An integrative view exploring this topic should take into account the following aspects: (i) the implication for glutamate, dopamine, and serotonin neurotransmission as demonstrated by genetic findings; (ii) the growing neuroimaging evidence of the common brain regions and dysfunctional circuits involved in both diseases; (iii) the pharmacological modulation of dopaminergic, serotoninergic, and glutamatergic systems as current therapeutic strategies in schizophrenia OCS; (iv) the recent discovery of midbrain dopamine neurons and dopamine D1- and D2-like receptors as orchestrating hubs in repetitive and psychotic behaviors; (v) the contribution of N-methyl-D-aspartate receptor subunits to both psychosis and OCD neurobiology. Finally, we discuss the potential role of the postsynaptic density as a structural and functional hub for multiple molecular signaling both in schizophrenia and OCD pathophysiology.

Abstract
BACKGROUND Obsessive-compulsive disorder (OCD) affects 2% to 3% of adults worldwide. Although serotonin reuptake inhibitors (SRIs) reliably demonstrate efficacy for this condition, 40% to 60% of patients only achieve partial recovery. The purpose of this systematic review was to assess the efficacy of other agents that may be used as augmentation agents for patients who are partial responders to SRI monotherapy. METHODS Using PRISMA-P guidelines, PubMed and Embase were searched using the randomized controlled trial (RCT) filter and the key word "obsessive-compulsive disorder." To be considered for analysis, a potential augmentation agent needed to have at least 2 RCTs. This review specifically analyzes the effect of each augmentation agent on OCD symptoms as measured by the Yale-Brown Obsessive-Compulsive Scale. RESULTS The augmentation agents analyzed in this review are d-cycloserine (2 RCTs), memantine (4 RCTs), N-acetylcysteine (5 RCTs), lamotrigine (2 RCTs), topiramate (3 RCTs), riluzole (2 RCTs), ondansetron (2 RCTs), celecoxib (2 RCTs), aripiprazole (5 RCTs), risperidone (7 RCTs), quetiapine (9 RCTs), and olanzapine (3 RCTs). IMPLICATIONS The augmentation agents most supported by this review for OCD that is only a partial response to SRI monotherapy are lamotrigine, memantine, and aripiprazole. If an antipsychotic must be used and aripiprazole is not tolerated, risperidone may be considered as an alternative. Unlike the SRI class effect for OCD symptom reduction, augmentation agents demonstrate considerable intraclass variability.

Abstract
Comorbid obsessive-compulsive disorder (OCD) is common among patients with schizophrenia. The role of electroconvulsive therapy (ECT) in the treatment of OCD in schizophrenia is unclear. Herein, we present a 45-year-old man who was diagnosed with schizophrenia along with OCD and received ECT due to relapse of psychosis owing to refractive schizophrenia. Together with psychotic symptoms, obvious symptoms of OCD were observed prior to treatment, including obsessive thoughts, difficulty in starting activities, and repetitive and ritualistic behavior. After 12 sessions of ECT, symptoms of schizophrenia and OCD both improved significantly (Positive and Negative Syndrome Scale [PANSS] score decreased from 95 points to 58 points, and Yale - Brown Obsessive-Compulsive Scale [Y-BOCS] score decreased from 29 points to 11 points). Mild aggravation of OCD symptoms was noted 3 months after ECT treatment (Y-BOCS score increased from 11 points to 17 points) without obvious relapse of psychotic symptoms (PANSS score changed from 58 points to 62 points). In conclusion, ECT could be considered as an alternative therapy for patients with schizophrenia and OCD with limited response to pharmacological treatment.

Abstract
BACKGROUND Schizophrenia patients often show obsessive-compulsive symptoms (OCS) and obsessive-compulsive disorder (OCD) and their presence has been associated with poorer prognosis. However, the impact of OCS/OCD on psychotic severity remains unclear. The aim of this study is twofold: 1) to investigate the effect of OCS/OCD on the severity of positive, negative, and global psychotic symptoms of schizophrenia patients and 2) to analyze the effect of patient and study-related covariates on moderating this relationship. METHODS A systematic review and meta-analysis (SRMA) of studies comparing the severity of psychotic symptoms among schizophrenia patients with and without OCS/OCD was performed. Standardized mean difference (SMD) was calculated for positive, negative, and global psychotic symptoms. The difference of SMD (Diff SMD) was calculated to analyze the effect of covariates on study outcomes using meta-regression. RESULTS Sixty-seven studies involving 7740 patients were included. Patients with schizophrenia and OCS/OCD showed a slightly higher severity of positive (SMD = 0.17, p value = 0.0089) and global psychotic symptoms (SMD = 0.24, p value = 0.0104) than patients without OCS/OCD but no differences in negative symptoms were found between groups (SMD = 0.11, p value = 0.0367). Only one covariate "proportion of patients without antipsychotics (AP)" was found to modify the effect on psychotic severity (Diff SMD = -0.008, p value = 0.002). CONCLUSIONS Comorbid OCS/OCD in schizophrenia has, at most, a minor impact on psychotic severity. Variability in this effect was considerable and was poorly explained by the covariates analyzed.

Abstract
Serotonin reuptake inhibitor (SRI) medications are well established as first-line pharmacotherapeutic treatment for Obsessive-Compulsive Disorder (OCD). However, despite the excellent safety profile and demonstrated efficacy of these medications, a substantial proportion of individuals with OCD fail to attain sufficient benefit from SRIs. In this narrative review, we discuss clinical features of OCD that have been associated with poorer response to SRIs, and we present pharmacotherapeutic interventions that have been explored as augmenting or alternative treatments for treatment-resistant OCD. We additionally highlight non-SRI interventions for OCD that are currently under investigation. Pharmacotherapeutic interventions were identified via expert consensus. To assess the evidence base for individual pharmacotherapies, targeted searches for relevant English-language publications were performed on standard biomedical research databases, including MEDLINE. Information relevant to ongoing registered clinical trials in OCD was obtained by search of ClinicalTrials.gov. Pharmacotherapies are grouped for review in accordance with the general principles of Neuroscience-based Nomenclature (NbN). Clinical features of OCD that may suggest poorer response to SRI treatment include early age of onset, severity of illness, duration of untreated illness, and the presence of symmetry/ordering or hoarding-related symptoms. Based on evolving pathophysiologic models of OCD, diverse agents engaging serotonin, dopamine, norepinephrine, glutamate, and anti-inflammatory pathways have been explored as alternative or adjunctive therapies for treatment-resistant OCD and have at least preliminary evidence of efficacy. Medications with dopamine antagonist activity remain the most robustly evidence-based of augmenting interventions, yet dopamine antagonists benefit only a minority of those who try them and carry elevated risks of adverse effects. Interventions targeting glutamatergic and anti-inflammatory pathways are less well evidenced, but may offer more favorable benefit to risk profiles. Ongoing research should explore whether specific interventions may benefit individuals with particular features of treatment-resistant OCD.

Abstract
OCD is characterized by obsessions and compulsions that cause distress, are time-consuming, and interfere with a patient's social, occupational, or other areas of functioning. SSRIs are first-line pharmacologic treatment options and produce response rates of up to 60% in patients with OCD. Several potential strategies have been evaluated for enhancing patient response, including high-dose SSRI therapy, antipsychotic augmentation, and memantine augmentation. Three patient cases are used to explore treatment guidelines, evaluate existing literature, and provide pharmacotherapy recommendations for the management of patients with OCD when first-line therapy fails.

Abstract
Obsessive Compulsive Disorder (OCD) is a common mental disorder that often causes great sufferance, with substantial impairment in social functioning and quality of life and affects family and significant relationships. Notwithstanding its severity, OCD is often not adequately diagnosed, or it is diagnosed with delay, leading often to a long latency between onset of the OCD symptoms and the start of adequate treatments. Several factors contribute to the complexity of OCD's clinical picture: early age of onset, chronic course, heterogeneity of symptoms, high rate of comorbidity with other psychiatric disorders, slow or partial response to therapy. Therefore, it is of primary importance for clinicians involved in diagnosing OCD, to assess all aspects of the disorder. This narrative review focuses on the global assessment of OCD, highlighting crucial areas to explore, pointing out the clinical features which are relevant for the treatment of the disorder, and giving an overview of the psychometric tools that can be useful during the screening procedure.

Abstract
There is little doubt that schizophrenia (SZ) and obsessive-compulsive disorder (OCD) are among the most severe disorders to impact humanity. They are both common, significantly disabling and have the tendency to strike during critical developmental periods in a young person's life. Schizophrenia affects approximately 1% of the global population and OCD has a lifetime prevalence of between 2% and 3% in the general population. The comorbidities in both SZ and OCD are common and frequently diagnosed, and research has generally found that comorbidities are associated with conditions that are more complex to diagnose and treat, and often result in less favorable prognoses. We review the research that has taken place regarding the co-occurrence of SZ and OCD, discuss it's theoretical conceptulization and clinical differentiation and diagnosis. We then propose recommendations for the best practice of cognitive behavioral therapy in this difficult population, as well as areas that need exploration for future research.

Abstract
Aripiprazole is a novel antipsychotic with a unique pharmacological profile as a dopamine partial agonist. It is indicated for treatment of schizophrenia and bipolar disorder. This new antipsychotic has low rate of extrapyramidal side effects, metabolic changes and no significant adverse effect on serum prolactin concentration. In addition,it is not associated with significant weight gain like other atypical antipsychotics. As a reason, when other antipsychotics cause these adverse events, it's not uncommon to switch to Aripiprazole. Obsessive compulsive symptoms have been untoward sequel of a few second-generation antipsychotics. Among the second generation antipsychotics Clozapine, Olanzapine, and Risperidone are the most prominent agents associated with these sequelae, according to case reports. More recently, a handful of case reports indicated development of Obsessive-compulsive symptoms with Aripiprazole. We report a case that exhibited similar unexpected adverse effects after administration of Aripiprazole. Keywords: Aripiprazole, Second generation antipsychotics, Obsessive-compulsive symptoms (OCS).

Abstract
OBJECTIVE A substantial proportion of patients with schizophrenia suffer from comorbid obsessive-compulsive disorder (OCD) possibly associated with antipsychotics. However, little is known about the comparative risks of the antipsychotics. The present study aimed to investigate the risk of new-onset OCD following the initiation of different antipsychotic medications for schizophrenia relative to haloperidol. METHODS Using the Korean national claims data, patients aged 15-60 years newly diagnosed with schizophrenia between 2010 and 2018 were identified. Of the 47,808 patients with schizophrenia treated with nine commonly prescribed antipsychotics, 775 new-onset OCD patients were matched to 3,100 patients without OCD using nested case-control design with 1:4 case-control matching based on the sex, age of index date, date of schizophrenia diagnosis, observation period, locations of medical institutions, and level of medical facilities. Using multivariable conditional logistic regression analysis, odd ratios (ORs) for new-onset OCD comparing each antipsychotic agent relative to haloperidol were computed. RESULTS The risk for new-onset OCD during treatment with clozapine was significantly higher than that with haloperidol (adjusted OR 2.86; 95% confidence interval [1.63-5.03]). The risks for new-onset OCD with other antipsychotics were not significantly different from that with haloperidol. In subgroup analysis, the early and intermediate, but not late-onset schizophrenia group showed significant risk for OCD associated with clozapine use. CONCLUSION The present findings, based on real-world national representative data, provide reliable evidence for the risk of new-onset OCD in patients with schizophrenia receiving clozapine at a population level.

Abstract
The aim of this study was to investigate the clinical risk factors, phenomenology and the impact of clozapine induced obsessive-compulsive symptoms (OCS) in patients with schizophrenia. One hundred twenty-two patients receiving clozapine treatment for at least 6 weeks were assessed with Structured Clinical Interview for Axis-I Disorders for DSM-IV, Positive and Negative Syndrome Scale, Yale-Brown Obsessive Compulsive Scale and Checklist, Calgary Depression Scale, Clinical Global Impression Scale and WHO-Disability Assessment Schedule-II. Information about past and current clinical status were gathered through clinical interviews and medical records. With clozapine 44.3% of the patients had de novo OCS, 33.6% had OCS both before and after clozapine, 21.3% didn't report any OCS. Clozapine doses, clozapine and norclozapine plasma levels were not significantly different. Severity of OCS was affected by clozapine and norclozapine plasma levels, and correlated with increased disability. Obsessions were less in clozapine induced OCS group, and compulsions, especially of checking subtypes, were predominant, compared to the group with prior history of OCS, who reported a significant increase in checking compulsion after clozapine treatment. Clozapine induced OCS should be considered during cost/benefit assessment of clozapine treatment, and understanding the risk factors and its different phenomenology may shed light into the underlying mechanisms.

Abstract
Introduction
Conventional treatment guidelines of schizophrenia do not necessarily provide solutions on clinically important issues.
Methods
A total of 141 certified psychiatrists of the Japanese Society of Clinical Neuropsychopharmacology evaluated treatment options regarding 19 clinically relevant situations in the treatment of schizophrenia with a 9-point scale (1=“disagree” and 9=“agree”).
Results
First-line antipsychotics varied depending on predominant symptoms: risperidone (mean±standard deviation score, 7.9±1.4), olanzapine (7.5±1.6), and aripiprazole (6.9±1.9) were more likely selected for positive symptoms; aripiprazole (7.6±1.6) for negative symptoms; aripiprazole (7.3±1.9), olanzapine (7.2±1.9), and quetiapine (6.9±1.9) for depression and anxiety; and olanzapine (7.9±1.5) and risperidone (7.5±1.5) for excitement and aggression. While only aripiprazole was categorized as a first-line treatment for relapse prevention (7.6±1.0) in patients without noticeable symptoms, aripiprazole (8.0±1.6) and brexpiprazole (6.9±2.3) were categorized as such for social integration. First-line treatments in patients who are vulnerable to extrapyramidal symptoms include quetiapine (7.5±2.0) and aripiprazole (6.9±2.1).
Discussion
These clinical recommendations represent the expert consensus on the use of a particular antipsychotic medication for a particular situation, filling a current gap in the literature.

Abstract
BACKGROUND Genetic risk factors that contribute to obsessive-compulsive disorder (OCD) have yet to be elucidated. Historically, serotonergic dysfunction has been implicated. Evidence from the literature points towards the serotonin receptor 2A gene (HTR2A) as a primary candidate. Our meta-analysis investigated whether polymorphisms in HTR2A are associated with OCD or its subtypes, based on sex and age of onset. METHODS Studies employing case-control or family-based designs were systematically searched, and those meeting eligibility underwent quality assessment, resulting in 18 studies. A random-effects meta-analysis using standard inverse-variance weighting to compute odds ratio (OR) was conducted. To examine sensitivity, results were also obtained using a more conservative statistical method. RESULTS Three HTR2A variants were identified: T102C, G-1438A, and C516T. T102C and G-1438A were analyzed together due to strong linkage disequilibrium, where the 102T allele co-occurs with -1438A allele. Results reported as OR [95%CI] showed that the T/A allele were significantly associated with OCD, 1.14 [1.01, 1.29]. After stratification, results remained significant for females, 1.20 [1.00, 1.45], and early-onset OCD, 1.27 [1.02, 1.58], but not males, 1.06 [0.91, 1.23]. No associations were found for late-onset OCD, 0.98 [0.70, 1.37], or C516T, 1.22 [0.14, 10.37], but conclusions cannot be drawn from two studies. LIMITATIONS Associations no longer reached significance with the conservative statistical approach. HTR2A alone cannot explain OCD complexity and limited samples reporting genetic data according to subtypes. CONCLUSIONS These results suggest a possible association of HTR2A polymorphisms with OCD, but further investigations considering sex and age of onset with larger samples is needed.

Abstract
SUMMARYThe comorbidity of obsessive–compulsive symptoms (OCS) in the context of schizophrenia is often not recognised by clinicians, and patients may not report these symptoms until they become severe. However, there is a reported prevalence of 10–24% for obsessive–compulsive disorder (OCD) in schizophrenia and related disorders. The onset of OCS/OCD has been noted to occur both before and after the diagnosis of schizophrenia or schizoaffective disorder. It has also been known to occur following commencement of treatment with antipsychotic medications, especially clozapine. Current literature provides limited guidance for treatment. Review of the current evidence supports: addition of selective serotonin reuptake inhibitors (SSRIs) to antipsychotics; addition of aripiprazole, amisulpride or lamotrigine; or reduction in the dosage of clozapine. There is also evidence supporting the addition of cognitive–behavioural therapy and electroconvulsive therapy (ECT). The SSRIs that are evidenced to be useful are fluvoxamine, escitalopram, sertraline and paroxetine. More studies are needed to expand the evidence base. Early targeted interventions are recommended.

Abstract
OBJECTIVE Patients with OCD differ markedly from one another in both number and kind of comorbid disorders. In this study, we set out to identify and characterize homogeneous subgroups of OCD patients based on their comorbidity profile. METHODS In a cohort of 419 adult subjects with OCD, the lifetime presence of fifteen comorbid disorders was assessed. Latent class analysis was used to identify comorbidity-based subgroups. Groups were compared with regard to core clinical characteristics: familiality, childhood trauma, age at onset, illness severity, OCD symptom dimensions, personality characteristics, and course of illness. RESULTS The study sample could be divided in a large group (n = 311) with a low amount of comorbidity that could be further subdivided into two subgroups: OCD simplex (n = 147) and OCD with lifetime major depressive disorder (n = 186), and a group (n = 108) with a high amount of comorbidity that could be further subdivided into a general anxiety-related subgroup (n = 49), an autism/social phobia-related subgroup (n = 27), and a psychosis/bipolar-related subgroup (n = 10). Membership of the high-comorbid subgroup was associated with higher scores on childhood trauma, illness severity, and the aggression/checking symptom dimension and lower scores on several personality characteristics. CONCLUSION Grouping OCD patients based on their comorbidity profile might provide more homogeneous, and therefore, more suitable categories for future studies aimed at unraveling the etiological mechanisms underlying this debilitating disorder.

Abstract
Freud argues that the laws of classical logic do not hold true with regard to the unconscious. The aim of this paper is to provide an alternative logic that is consistent with Freud's conception of the unconscious. This aim is achieved in two steps. First, I argue that most Freudian features of the unconscious are consequences of the fact that unconscious thoughts in the Freudian sense are negationless. Then I suggest a formal logical system that lacks the negation symbol, and is known as negationless-logic, with which to formulate the logic of the unconscious. I demonstrate that this suggestion provides a better understanding of various psychological phenomena, such as projection, reaction-formation, delusion and the misconstrual of the empty set in childhood. Finally, I argue that negationless-logic provides solutions to certain shortcomings in Matte-Blanco's formulation of the logic of the unconscious.

Abstract
BACKGROUND It is not uncommon to find obsessive-compulsive symptoms (OCS) in patients treated with clozapine. These symptoms are attributed to anti-serotonergic effects of clozapine. The objective of this study was to conduct a systematic review of reported cases of clozapine-associated OCS to better understand the nature and management of these symptoms. METHODS MEDLINE, Embase, and PsycINFO databases were searched with no publication year or language restrictions. Studies reporting cases of clozapine-associated OCS, either de novo or exacerbation of preexisting OCS, were included. The final search date was July 11, 2019. RESULTS Fifty-seven studies, involving 107 cases (75 de novo, 32 exacerbated OCS), were included. Clozapine triggered moderate-severe OCS at varying doses (100-900 mg/day) and treatment durations (median 6 months, interquartile range 2-24 months). Higher severity was significantly associated with preexisting OCS, poorer insight into OCS, and active psychosis at the time of OCS. Common strategies to treat clozapine-associated OCS included adding selective serotonin reuptake inhibitors, clomipramine, or aripiprazole, often accompanied by clozapine dose reduction. The rate of response to antidepressants was 49% (29/59), where younger age, shorter duration of underlying illness, shorter cloza-pine treatment duration, better insight into OCS, and presence of taboo thoughts were significantly associated with antidepressant response. Subsequent clozapine dose reduction was effective in many non-responders, where aripiprazole was simultaneously added in 50% (8/16). CONCLUSIONS Clozapine can trigger severe OCS. Adding aripiprazole with/without clozapine dose reduction may be a good alternative to antidepressants for managing clozapine-associated OCS. Clinicians should be more vigilant about these adverse effects and administer appropriate treatments.

Stefanou MI, Vittore D, Wolz I, Klingberg S, Wildgruber D. Recurrent Episodes of Paraphilic Behavior Possibly Associated With Olanzapine and Aripiprazole Treatment in a Patient With Schizophrenia. Front Psychiatry 2020; 11:318. [PMID: 32425825 PMCID: PMC7212450 DOI: 10.3389/fpsyt.2020.00318] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/27/2020] [Accepted: 03/31/2020] [Indexed: 01/18/2023] Open
Abstract
BACKGROUND Hypersexual and paraphilic disorders have been frequently associated with concomitant psychiatric disorders, including schizophrenia. A growing number of published cases has recently indicated that hypersexual behavior may also arise in conjunction with treatment with second-generation antipsychotics. Although hypersexuality has been acknowledged as a possible side effect of antipsychotic treatment with partial dopamine agonists, including aripiprazole, only very few cases of olanzapine-associated hypersexuality have been reported in the literature. CASE PRESENTATION A 29-year-old man presented with delusions of persecution and reference, auditory hallucinations, and negative symptoms, and was diagnosed with paranoid-hallucinatory schizophrenia. One and a half months after initiation of antipsychotic treatment with olanzapine, he developed compulsive sexual behavior and paraphilia, without signs of akathisia. After olanzapine discontinuation, a full remission of the hypersexual behavior was noted within one week, and treatment was switched to risperidone. Due to hyperprolactinemia, adjunct treatment with low-dose aripiprazole was initiated and a severe recurrence of identical hypersexual behavior occurred. The hypersexual behavior resolved completely within a week after aripiprazole discontinuation. CONCLUSION This case illustrates that hypersexuality may be a rare adverse effect of treatment with second-generation antipsychotics. Although aripiprazole is a drug with a well-established risk for hypersexuality, the question of whether a causal association between hypersexuality and olanzapine exists remains currently unresolved. As the currently limited amount of available evidence precludes any definitive conclusions, additional research is warranted to delineate the possible neurobiological substrates of hypersexual and paraphilic disorders in patients treated with second-generation antipsychotics.

Abstract
PURPOSE OF REVIEW This article reviews current knowledge regarding diagnosis, pathophysiology, and treatment trends in obsessive-compulsive disorder (OCD), a severe, underrecognized, and chronic condition frequently encountered in neurologic practice. RECENT FINDINGS With a lifetime prevalence estimated at 2.5%, OCD is a common condition that can also present comorbidly with neurologic disease. The core symptoms of OCD are obsessions and compulsions. Obsessions are intrusive repetitive thoughts, urges, images, or impulses that trigger anxiety and that the individual is not able to suppress. Compulsions are repetitive behaviors or mental acts occurring in response to an obsession with the intention of reducing the distress caused by obsessions. Neuroimaging, neuropsychological, and pharmacologic studies suggest that the expression of OCD symptoms is associated with dysfunction in a cortico-striato-thalamo-cortical circuit. Evidence-based treatments for OCD comprise pharmacotherapy and cognitive-behavioral therapy. Selective serotonin reuptake inhibitors (SSRIs) are the first-line drugs recommended for OCD, but significant differences exist in their use for OCD compared to their use for other mood and anxiety conditions, including the need for higher dosage, longer trials necessitated by a longer lag for therapeutic response, and typically lower response rates. Cognitive-behavioral therapy, based on the principles of exposure and response prevention, shows results superior to pharmacologic treatments with lower relapse rates on long-term follow-up and thus should be considered in the treatment plan of every patient with OCD. SUMMARY OCD and obsessive-compulsive symptoms are frequently encountered in the neurologic clinic setting and require a high index of suspicion to effectively screen for them and an illness-specific therapeutic approach.

Abstract
PURPOSE OF REVIEW This review will aim to summarize the current body of epidemiological, clinical and therapeutic knowledge concerning specific co-occurrence of obsessive-compulsive symptoms (OCSs) and schizophrenia spectrum disorder. RECENT FINDINGS Almost 30% of the patients with schizophrenia display OCS, and three main contexts of emergence are identified: prodromal symptoms of schizophrenia, co-occurrence of OCS and schizophrenia and antipsychotics-induced OCS. Recent clinical studies show that patients with SZ and OCS have more severe psychotic and depressive symptoms, higher suicidality and lower social functioning. A recent cognitive investigation found that OCS and delusions share specific metacognitive profiles, particularly through a heightened need to control thoughts. Finally, a recent cross-sectional study of clozapine-induced OCS found a dose-response relationship between clozapine and OCS. OCS appeared reliably as linked to poorer outcomes among patients with schizophrenia. However, the specific clinical value of OCS among other prodromal symptoms of schizophrenia remains unknown.

Abstract
OBJECTIVE To review the available literature on obsessive-compulsive symptom (OCS)/obsessive-compulsive disorder (OCD) in patients with schizophrenia. METHODOLOGY Electronic searches were carried out to locate studies reporting various aspects of OCS/OCD in patients with schizophrenia. RESULTS Available evidence suggests that prevalence of OCS/OCD in patients with schizophrenia is much higher than prevalence in general population and it is seen in all the stages of schizophrenia, starting from at risk mental state to chronic/stabilisation/deficit phases. Symptom profile of OCS/OCD in schizophrenia is similar to that seen in patients with OCD only. Presence of OCS/OCD is associated with higher severity of symptoms of schizophrenia and more negative outcome. At present there is very limited data on the efficacy/effectiveness of various pharmacological measures and psychological interventions, for management of OCS/OCD in patients with schizophrenia. There is some evidence pointing towards beneficial effect of certain antipsychotics, antidepressants and cognitive behaviour therapy. Management of OCS/OCD in patients with schizophrenia involves proper assessment. If the OCS/OCD is related to use of particular antipsychotic use, initial attempt must be made to reduce the dose of antipsychotics, however, if this is not effective, than addition of a selective serotonin reuptake inhibitor (SSRIs) must be considered. If the OCS/OCD is not related to the use of antipsychotic medication, than depending up on the severity of psychotic symptoms, addition of SSRIs must be considered. CONCLUSION This review suggests that OCS/OCD is highly prevalent among patients with schizophrenia and there is limited good quality evidence to make any specific recommendations for management.

Abstract
Obsessive Compulsive Disorder (OCD) and Obsessive Compulsive Symptoms (OCS) are known to be highly comorbid with bipolar disorder and schizophrenia. Comorbid OCD/OCS influences the course of schizophrenia and bipolar disorder. There is also some evidence to suggest that a diagnosis of OCD may be associated with elevated risk for later development of psychosis and bipolar disorder. Comorbid OCD/OCS is associated with a greater severity of schizophrenia phenotype and poorer prognosis. In addition, certain atypical antipsychotics, clozapine in particular are known to induce or worsen OCS in schizophrenia. OCD when comorbid with bipolar disorder mostly runs an episodic course with worsening and improvement of OCD/OCS in depressive and in manic/hypomanic phases respectively. There is limited systematic data on the treatment of OCD in schizophrenia and bipolar disorder. When OCD presents in the context of schizophrenia, management may include treatment with atypical antipsychotics with limited serotonergic properties, changing the antipsychotic, reduction in the dose of the antipsychotic, addition of cognitive-behavior therapy (CBT), or a specific serotonin reuptake inhibitor (SSRI). When OCD is comorbid with bipolar disorder, mood stabilization is the priority. CBT may be preferred over SSRIs to treat OCD/OCS that persist in between the mood episodes because SSRIs may induce a switch or worsen the course of bipolar disorder. SSRIs when indicated have to be used judiciously under the cover of adequate mood stabilization.

Abstract
AIM To carryout factor analysis of symptom profile of patients with schizophrenia assessed by using positive and negative syndrome scale (PANSS), Calgary depression rating scale (CDSS), Young mania rating scale (YMRS) and YBOCS checklist. METHODOLOGY 181 patients of schizophrenia were assessed on PANSS, CDSS, YMRS and YBOCS checklist. RESULTS Factor analysis of PANSS yielded 3 factor structure (positive, negative, anxiety). When the items of CDSS were added to the PANSS items, total number of factors increased to 4 with depression emerging as a separate factor. Addition of YMRS to PANSS and CDSS led to emergence of 5 factor model. Further addition of YBOCS checklist led to emergence of a 7 factor model (positive, depressive, obsessive compulsive, negative, manic, anxiety and obsessive compulsive-2), which explained 49.85% variance of the data. Positive symptoms emerged as the factor-1. Depressive symptoms loaded on the factor-2, negative symptoms loaded on to factor-4, manic symptoms loaded onto factor-5 and anxiety symptoms loaded onto factor-6. OC symptoms loaded onto factor 3 and 7. CONCLUSIONS Present study suggests that when multiple scales are used for assessment of various symptoms of schizophrenia, the symptoms separate out into 7 factors. This finding suggests that clinical assessment of schizophrenia should not be limited to core psychotic symptoms only and structured instruments must be used to elicit other symptoms too while monitoring the clinical picture of patients with schizophrenia.

Abstract
Management of obsessive compulsive disorder (OCD) remains a challenge, particularly in individuals having co-existing psychotic symptoms. Even in patients with schizophrenia having a fair to good response in psychotic symptoms, these obsessive-compulsive symptoms defy response to antipsychotic and anti-obsessive pharmaco-therapeutic approach to a great extent. Recently developed neuromodulation techniques such as transcranial direct current stimulation (tDCS) can serve a viable and effective approach to manage such cases. The present paper documents the first utilization of tDCS (cathode: supplementary motor area; anode: right occipital cortex) as an add-on approach to pharmacotherapy to manage co-morbid OCD in a case of chronic schizophrenia.

Abstract
Skin-picking disorder is regarded as a type of obsessive-compulsive and related disorders according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Selective serotonin reuptake inhibitors (SSRIs) are reported to be effective in the treatment of skin-picking disorder. However, these agents can cause opposite effects in some cases. There is a report on SSRI-induced skin-picking disorder in adults. However, to our knowledge, there are no data regarding SSRI-induced skin picking in children. We present the case of a preschool girl with separation anxiety disorder who displayed skin-picking and compulsive-asking behaviors after fluoxetine therapy.

Abstract
PURPOSE OF REVIEW The purpose of this review was to assess and present the findings up to this date on the efficacy of antipsychotics in the treatment of generalized anxiety disorders (GAD), social anxiety disorders (SAD), panic disorders (PD), and obsessive-compulsive disorders (OCD), mostly based on published randomized controlled trials (RCTs) or on open-label studies when RCT were lacking. RECENT FINDINGS Quetiapine could be recommended in patients with GAD. The efficacy of aripiprazole in two open-label studies on patients with antidepressant-refractory GAD should be assessed in RCTs. Despite preliminary positive results in open studies, there are currently no strong evidence for the effectiveness of antipsychotics in refractory SAD and in refractory PD. Conversely, risperidone and aripiprazole can be used for the treatment of refractory OCD as augmentation agents to antidepressants. Contrary to SAD and PD, this review found evidence for the use of second-generation antipsychotics in GAD and OCD. Otherwise, first-generation antipsychotics cannot be recommended in anxiety disorders and OCD.

Abstract
The presence of obsessive-compulsive symptoms (OCS) and obsessive-compulsive disorders (OCD) in schizophrenia is frequent, and a new clinical entity has been proposed for those who show the dual diagnosis: the schizo-obsessive disorder. This review scrutinizes the literature across the main academic databases, and provides an update on different aspects of schizo-obsessive spectrum disorders, which include schizophrenia, schizotypal personality disorder (SPD) with OCD, OCD with poor insight, schizophrenia with OCS, and schizophrenia with OCD (schizo-obsessive disorder). An epidemiological discussion on the discrepancies observed in the prevalence of OCS and OCD in schizophrenia across time is provided, followed by an overview of the main clinical and phenomenological features of the disorder in comparison to the primary conditions under a spectral perspective. An updated and comparative analysis of the main genetic, neurobiological, neurocognitive, and pharmacological treatment aspects for the schizo-obsessive spectrum is provided, and a discussion on endophenotypic markers is introduced in order to better understand its substrate. There is sufficient evidence in the literature to demonstrate the clinical relevance of the schizo-obsessive spectrum, although little is known about the neurobiology, genetics, and neurocognitive aspects of these groups. The pharmacological treatment of these patients is still challenging, and efforts to search for possible specific endophenotypic markers would open new avenues in the knowledge of schizo-obsessive spectrum.

Abstract
The aim of this study was to evaluate the prevalence of comorbid obsessive compulsive symptoms/disorder and its impact on outcome among patients with schizophrenia. 181 patients with schizophrenia were evaluated on Yale-Brown Obsessive-Compulsive Symptom Checklist, Yale-Brown Obsessive-Compulsive Scale, Calgary Depression Scale for Schizophrenia, Positive and Negative Symptom Scale, Social Occupational Functioning Scale, Global Assessment of Functioning Scale and Indian Disability Evaluation and Assessment Scale. Slightly more than one-fourth of patients fulfilled the diagnosis of current (28.2%) and lifetime (29.8%) diagnosis of obsessive compulsive disorder. On Yale Brown Obsessive Compulsive Symptom Checklist, the most common lifetime obsessions were those of contamination (25.4%), followed by obsessions of need for symmetry or exactness (11.6%). The most common compulsions were those of cleaning/washing (27.1%), followed by those of checking (24.3%). Presence of obsessive compulsive symptoms was associated with younger age of onset, higher prevalence of comorbid depression, and current suicidal ideations. Thus, it can be concluded that a significant proportion of patients with schizophrenia have obsessive compulsive symptoms/disorder. Clinicians managing patients of schizophrenia should evaluate the patients thoroughly for presence of comorbid obsessive compulsive symptoms/disorder and must take the same into account while managing the patients.

Abstract
The prevalence of OCS and OCD is higher in schizophrenic patients than in the general population. These disorders are sometimes induced by AAPs. There is higher frequency of OCS and greater severity in patients treated with antipsychotics with predominant anti-serotoninergic profiles opposed to those with predominant dopaminergic blockade. Induced OCS may be due to complex neuromodulation involving many serotonin, dopamine and glutamate receptors and several subtypes. Concerning connectivity, AAPs differentially influence the BOLD signal, depending on the intensity of D2 receptor blockade. The OFC could play a significant role, on account of its involvement in inhibitory control. There is a paradox: AAPs are efficient as augmentation to SSRI in treatment resistant OCD, some of them such as risperidone or aripiprazole have favourable effects in schizoptypic OCD, but AAPs cause induced OCS in schizophrenic patients. When prescribing AAPs, we should inform patients about this potential side effect and assess systematically OCS with Y-BOCS assessment after 1 month of treatment. Afterwards there are different strategies: Aripiprazole in combination can reduce OCS induced by clozapine, SSRI are slightly effective and CBT shows a few encouraging results. OCS are sometimes dose-dependent, so we also recommend prescribing the minimum effective dose and gradual introduction.

Abstract
AIM To review available evidence on the use of cognitive behavioural therapy (CBT) for treating obsessive compulsive disorder co-occurring with psychosis.
METHODS In this paper we present a detailed and comprehensive review of the current literature focusing on CBT treatment of obsessive compulsive disorder (OCD) co-occurring with schizophrenia or schizoaffective disorder. We identified relevant literature published between 2001 and May 2016 through MEDLINE/PubMed search using as search string (“obsessive compulsive disorders” or “obsessive compulsive symptoms”) and (“schizophrenia” or “schizoaffective disorder” or “psychosis”) and (“cognitive behavioural therapy”). Other citations of interest were further identified from references reported in the accessed articles. The search was limited to studies written in English and carried out in adult patients. A total of 9 studies, 8 case reports and 1 case series, were found.
RESULTS The reviewed evidence indicates that CBT is: (1) safe, i.e., does not worsen psychotic symptoms; (2) well accepted, with a discontinuation rate quite similar to that reported for patients with OCD without psychosis comorbidity; (3) effective, with a symptom reduction quite similar to that reported for patients with OCD without psychosis and for SRIs treatment of OCD co-occurring with psychosis; and (4) effective in patients with OCD induced by second-generation antipsychotic as well as in patients with OCD not induced by second-generation antipsychotic. Alcohol/substance use disorder comorbidity and OCD onset preceding that of SCH/SA was predictors of poor outcome. These results are derived only by additional studies with adequate sample size.
CONCLUSION Our results support the use of CBT for OCD in patients with psychosis.

Abstract
Pathological hair-pulling or trichotillomania, which is commonly associated with anxiety and depression, obsessive-compulsive disorder, and neurodevelopmental disorders, has been rarely associated with dementing illnesses. Investigators have not clarified the neural correlates and treatment of trichotillomania in dementia. We report a patient who developed an early-onset cognitive decline with genetic, cerebrospinal fluid biomarker and structural and functional neuroimaging studies consistent with Alzheimer's disease. Eight years into her disease, she developed severe, repetitive hair-pulling behavior leading to marked hair loss, along with other repetitive and “frontal” behaviors. Selective serotonin reuptake inhibitors (SSRIs) were ineffective in controlling her hair-pulling behavior, which subsequently responded to quetiapine 150 mg/day. This patient and a review of the literature suggest that trichotillomania may be a compulsive-related symptom in dementias of different etiologies as they involve frontal areas and release primitive grooming behavior from frontostriatal dysfunction. Dopamine blockade, rather than SSRIs, may be effective in managing trichotillomania in dementia.

Rodent models of obsessive compulsive disorder: Evaluating validity to interpret emerging neurobiology. Neuroscience 2016; 345:256-273.

Abstract
Obsessive Compulsive Disorder (OCD) is a common neuropsychiatric disorder with unknown molecular underpinnings. Identification of genetic and non-genetic risk factors has largely been elusive, primarily because of a lack of power. In contrast, neuroimaging has consistently implicated the cortico-striatal-thalamo-cortical circuits in OCD. Pharmacological treatment studies also show specificity, with consistent response of OCD symptoms to chronic treatment with serotonin reuptake inhibitors; although most patients are left with residual impairment. In theory, animal models could provide a bridge from the neuroimaging and pharmacology data to an understanding of pathophysiology at the cellular and molecular level. Several mouse models have been proposed using genetic, immunological, pharmacological, and optogenetic tools. These experimental model systems allow testing of hypotheses about the origins of compulsive behavior. Several models have generated behavior that appears compulsive-like, particularly excessive grooming, and some have demonstrated response to chronic serotonin reuptake inhibitors, establishing both face validity and predictive validity. Construct validity is more difficult to establish in the context of a limited understanding of OCD risk factors. Our current models may help us to dissect the circuits and molecular pathways that can elicit OCD-relevant behavior in rodents. We can hope that this growing understanding, coupled with developing technology, will prepare us when robust OCD risk factors are better understood.

Abstract
Schizophrenia (SZ) has long been associated with a variety of cognitive deficits, including reduced cognitive flexibility. More recent findings, however, point to tremendous inter-individual variability among patients on measures of cognitive flexibility/set-shifting. With an eye toward shedding light on potential sources of variability in set-shifting abilities among SZ patients, I examine the neural substrates of underlying probabilistic reversal learning (PRL) - a paradigmatic measure of cognitive flexibility - as well as neuromodulatory influences upon these systems. Finally, I report on behavioral and neuroimaging studies of PRL in SZ patients, discussing the potentially influences of illness profile and antipsychotic medications on cognitive flexibility in SZ.

Psychosis or Obsessions? Clozapine Associated with Worsening Obsessive-Compulsive Symptoms. Case Rep Psychiatry 2016; 2016:2180748. [PMID: 27313938 PMCID: PMC4904080 DOI: 10.1155/2016/2180748] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2016] [Revised: 05/02/2016] [Accepted: 05/12/2016] [Indexed: 12/12/2022] Open
Abstract
One underrecognized adverse event of clozapine is the emergence or worsening of obsessive-compulsive symptoms (OCS). OCS, particularly violent thoughts, can be inaccurately described as psychosis and result in a misdiagnosis. We report a case of a 42-year-old man, initially diagnosed with schizoaffective, who was placed on clozapine for the management of “violent delusions.” However, clozapine led to a worsening of these violent thoughts resulting in suicidal ideation and hospitalization. After exploration of the intrusive thoughts and noting these to be egodystonic, clearly disturbing, and time consuming, an alternative diagnosis of obsessive-compulsive disorder (OCD) was made. Clozapine was inevitably discontinued resulting in a significant reduction of the intrusive thoughts without emergence of psychosis or adverse events. While an overlapping phenomenology between OCD and psychotic disorders has been described, clozapine and other antiserotonergic antipsychotics have been implicated with the emergence or worsening of OCS. Unique to our case is that the patient's obsessions had been treated as psychosis leading to the inadequate treatment of his primary illness, OCD. This case highlights the potential for OCD to masquerade as a psychotic disorder and reminds clinicians that clozapine may worsen OCS.

Abstract
Patients with schizophrenia have an increased lifetime risk of comorbid obsessive-compulsive symptoms. Up to 30% of these patients experience such symptoms and 12% may be diagnosed with obsessive-compulsive disorder. The presence of these symptoms in schizophrenia seems to be associated with poor outcomes including a greater suicidal risk. A subgroup of patients develops this symptomatology after the initiation with Second Generation Antipsychotics (SGA). Also, there is evidence of a causal relationship for this association, particularly for clozapine. The primary aim of this study was to investigate the association of this comorbidity with suicidality in a population of clozapine-medicated schizophrenic and schizoaffective patients (N=65). The prevalence of obsessive-compulsive symptoms in our sample was 29.2% (N=19) and the prevalence of obsessive-compulsive disorder was 13.8% (N=9). Significant positive correlations between suicidality and total Y-BOCS score and between Y- BOCS score and depressive symptoms were found. Further analysis indicated that a Y-BOCS score greater or equal than 8 was an independent predictor of suicide attempt during clozapine treatment. Routine screening for this adverse event should be warranted for this population.

Abstract
The prevalence of obsessive-compulsive disorder in subjects with psychotic disorder is much higher than in the general population. The higher than chance co-occurrence has also been demonstrated at the level of subclinical expression of both phenotypes. Both extended phenotypes have been shown to cluster in families. However, little is known about the origins of their elevated co-occurrence. In the present study, evidence for a shared etiological mechanism was investigated in 3 samples with decreasing levels of familial psychosis liability: 987 patients, 973 of their unaffected siblings and 566 healthy controls. The association between the obsessive-compulsive phenotype and the psychosis phenotype c.q. psychosis liability was investigated. First, the association was assessed between (subclinical) obsessive-compulsive symptoms and psychosis liability. Second, in a cross-sib cross-trait analysis, it was examined whether (subclinical) obsessive-compulsive symptoms in the patient were associated with (subclinical) psychotic symptoms in the related unaffected sibling. Evidence was found for both associations, which is compatible with a partially shared etiological pathway underlying obsessive-compulsive and psychotic disorder. This is the first study that used a cross-sib cross-trait design in patients and unaffected siblings, thus circumventing confounding by disease-related factors present in clinical samples.

Abstract
We focused on the application of antidepressants in schizophrenia treatment in this review. Augmentation of antidepressants with antipsychotics is a common clinical practice to treat resistant symptoms in schizophrenia, including depressive symptoms, negative symptoms, comorbid obsessive-compulsive symptoms, and other psychotic manifestations. However, recent systematic review of the clinical effects of antidepressants is lacking. In this review, we have selected and summarized current literature on the use of antidepressants in patients with schizophrenia; the patterns of use and effectiveness, as well as risks and drug-drug interactions of this clinical practice are discussed in detail, with particular emphasis on the treatment of depressive symptoms in schizophrenia.
