An Unexpected Phenomenon: A Case of Citalopram-Induced Dyskinesia.

Dyskinetic movements are characterized as hyperkinetic, repetitive movements of the extremities, facial, and oral musculature, most associated with prolonged dopamine D2 receptor blockade. In rare instances, dyskinetic movements can be brought on by selective serotonin reuptake inhibitor (SSRI) usage via an indirect D2 blockade mechanism, mimicking the D2 blockade observed with dopamine receptor blocking agents (DRBAs), such as in first-generation antipsychotics. This mimicked D2 blockade by SSRIs is said to be due to increased tonic inhibition by serotonin on dopaminergic neurons in the dopaminergic pathways of the brain, specifically the nigrostriatal pathway. In this case report, we look at a patient with a history of cerebral palsy who developed acute dyskinetic movements after short-term citalopram usage. The objective is to bring attention to the possible extrapyramidal side effects (EPS) of SSRI usage.

A 12-month longitudinal naturalistic follow-up of cariprazine in schizophrenia.

Background: Cariprazine, a third-generation antipsychotic (TGAs), has demonstrated efficacy in the treatment of schizophrenia with good tolerability profile. Actual real-world literature data are lacking, particularly when exploring its efficacy in the long term. The present study examined the effects of cariprazine treatment on specific psychopathological domains with a particular focus on outcomes and side effects in real-life experience, after a long-term treatment. Methods: The present 12-month longitudinal naturalistic study included a sample of subjects with a DSM-5-TR diagnosis of schizophrenia, recruited in the outpatients' psychiatric services of university and community hospitals in Italy, naturally treated with cariprazine. The assessments included: a sociodemographic data sheet, the Structured Clinical Interview for the DSM-5 (SCID-5), the Positive and Negative Symptom Scale (PANSS) and the St. Hans Rating Scale (SHRS). The PANSS was also administered after 6 (T1) and 12 (T2) months of treatment with cariprazine while the SHRS at T1. Results: The total sample consisted of 31 patients, 15 males and 16 females. A significant decrease of the PANSS' subscales, Marder factors and total mean scores emerged at both T1 and T2 with respect to T0. Extrapyramidal symptoms occurred in a minority of patients and in mild or mild/moderate forms: no patient showed moderate forms of psychic/motor akathisia or dystonia, three subjects showed moderate parkinsonism. Conclusions: This study confirms a good efficacy profile of cariprazine in both positive and negative symptoms in patients with Schizophrenia, combined with a good tolerability profile in extrapyramidal symptoms.

Comparative efficacy of akathisia treatments: A network meta-analysis.

OBJECTIVE: Akathisia, a common side effect of psychotropic medications, poses a significant challenge in neuropsychiatry, affecting up to 30% of patients on antipsychotics. Despite its prevalence, akathisia remains poorly understood, with difficulties in diagnosis, patient reporting, and treatment efficacy. This research aimed to shed light on effective interventions to improve akathisia management. METHODS: A systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted, encompassing controlled trials in English and Italian languages. Databases, such asPubMed, Scopus, and EMBASE, were searched until July 9, 2023. Treatment effectiveness was assessed using standardized mean differences (SMDs) in post-treatment akathisia scores. RESULTS: Thirteen studies involving 446 individuals met the inclusion criteria. Benzodiazepines, beta-blockers, and NaSSA demonstrated significant efficacy as compared with placebo. Anticholinergic, anticonvulsant, triptan, and other treatments did not show significant differences. Benzodiazepines ranked highest in P-scores (0.8186), followed by beta-blockers and NaSSA. CONCLUSIONS: Effective management of akathisia is crucial, with benzodiazepines, beta-blockers, and NaSSA offering evidence-based options. Treatment rankings provide guidance for clinicians. Future research should prioritize larger, more robust studies to address limitations associated with small sample sizes and publication bias. This research enhances our understanding of interventions for akathisia, offering promising options to improve patient quality of life and prevent complications related to non-adherence and mismanagement.

A descriptive analysis of spontaneous reports of antipsychotic-induced tardive dyskinesia and other extrapyramidal symptoms in the Japanese Adverse Drug Event Report database.

AimThe aim of this study is to summarize the spontaneous reports of tardive dyskinesia (TD) and extrapyramidal symptoms (EPSs) that occurred in Japan over the past decade. MethodsThe study analyzed TD and EPS cases reported in the Japanese Adverse Drug Event Report database between April 2011 and March 2021. The cases were stratified by the diagnoses of schizophrenia, bipolar disorders, and depressive disorders. ResultsIn total, 800 patients including a total of 171 TD cases and 682 EPS cases were reported in the JADER database across psychiatric diagnosis. The cases were caused by first-generation antipsychotics (FGA, TD: n = 105, EPS: n = 245) and second-generation antipsychotics (SGA, TD: n = 144, EPS: n = 598). The SGA were categorized based on Neuroscience-based Nomenclature (NbN) regarding pharmacological domain and mode of action, which were reported evenly as the offending agents. Among reported treatment and outcome in TD cases (n = 67, 37.6%) and EPS cases (n = 405, 59.3%), the relatively limited number of TD cases were reported as recovered/improved was also limited (n = 32, 47.8%) compared to those of EPS cases (n = 266, 65.7%). Some cases still had residual symptoms or did not recover fully (TD: n = 21, 31.3%, EPS: n = 77, 19.0%). CONCLUSION: Tardive dyskinesia and EPS have been widely reported in Japan over the past decade across psychiatric diagnoses and antipsychotic classes. LIMITATIONS: It is important to acknowledge the presence of reporting bias and the lack of comparators to accurately assess risks. Owing to the nature of spontaneous reporting, the estimation of prevalence is not feasible.

Improving the clinical monitoring of extrapyramidal symptoms: a local quality improvement project.

BACKGROUND: Extrapyramidal symptoms (EPS) can cause significant morbidity and impact negatively on patients' quality of life. Clinical guidelines provide recommendations regarding screening frequency and the use of structured tools to ensure adequate monitoring of EPS. Despite this, the literature indicates that the documentation and monitoring of EPS remain suboptimal. AIMS: To devise an intervention that would lead to the improvement in the documentation and hence monitoring of EPS. METHODS: An initial paper chart survey was conducted to assess the current extent of documentation and monitoring of EPS carried out in patient files of three distinct settings in our Mental Health Service (MHS): inpatient, rehabilitation, and assertive outreach. An intervention aimed at improving practice was subsequently designed and implemented. This involved adoption by the MHS of a new EPS monitoring tool and delivery of an educational session regarding its use. The extent of documentation and monitoring of EPS was re-surveyed post-intervention. RESULTS: Initially, only 14.8% of inpatient records contained evidence of EPS documentation while no evidence at all was found across the other two MHS settings. Following the intervention, there was evidence of guideline concordant EPS monitoring using a structured tool in the clinical records of 75% of inpatients, 79.6% in the rehabilitation setting, and 18% in the assertive outreach programme. CONCLUSION: Documentation of EPS monitoring improved significantly across several settings affiliated with a Dublin North City MHS following the systematic adoption of the Extrapyramidal Symptom Scale (EPSS) and clinician education regarding its use.

The Extrapyramidal Symptom Rating Scale and Its Abbreviated Version: A Critical Review of Clinimetric Properties.

BACKGROUND: The Extrapyramidal Symptom Rating Scale - Abbreviated (ESRS-A) is an abbreviated version of the Extrapyramidal Symptom Rating Scale (ESRS) with instructions, definitions, and a semi-structured interview that follows clinimetric concepts of measuring clinical symptoms. Similar to the ESRS, the ESRS-A was developed to assess four types of drug-induced movement disorders (DIMD): parkinsonism, akathisia, dystonia, and tardive dyskinesia (TD). SUMMARY: The present review of the literature provides the most relevant clinimetric properties displayed by the ESRS and ESRS-A in clinical studies. Comprehensive ESRS-A definitions, official scale, and basic instructions are provided. ESRS inter-rater reliability was evaluated in two pivotal studies and in multicenter international studies. Inter-rater reliability was high for assessing both antipsychotic-induced movement disorders and idiopathic Parkinson's disease. Guidelines were also established for inter-rater reliability and the rater certification processes. The ESRS showed good concurrent validity with 96% agreement between Abnormal Involuntary Movement Scale (AIMS) for TD-defined cases and ESRS-defined cases. Similarly, concurrent validity for ESRS-A total and subscores for parkinsonism, akathisia, dystonia, and dyskinesia ranged from good to very good. The ESRS was particularly sensitive for detecting DIMD-related movement differences following treatment with placebo, antipsychotics, and antiparkinsonian and antidyskinetic medications. ESRS measurement of drug-induced extrapyramidal symptoms was shown to discriminate extrapyramidal symptoms from psychiatric symptoms. KEY MESSAGES: The ESRS and ESRS-A are valid clinimetric indices for measuring DIMD. They can be valuably implemented in clinical research, particularly in trials testing antipsychotic medications, and in clinics to detect the presence, severity, and response to treatment of movement disorders.

Oleanolic acid alleviates the extrapyramidal symptoms and cognitive impairment induced by haloperidol through the striatal PKA signaling pathway in mice.

Haloperidol, one of the representative typical antipsychotics, is on the market for schizophrenia but shows severe adverse effects such as extrapyramidal symptoms (EPS) or cognitive impairments. Oleanolic acid (OA) is known to be effective for tardive dyskinesia which is induced by long-term treatment with L-DOPA. This study aimed to investigate whether OA could ameliorate EPS or cognitive impairment induced by haloperidol. The balance beam, catalepsy response, rotarod and vacuous chewing movement (VCM) tests were performed to measure EPS and the novel object recognition test was used to estimate haloperidol-induced cognitive impairment. Levels of dopamine and acetylcholine, the phosphorylation levels of c-AMP-dependent protein kinase A (PKA) and its downstream signaling molecules were measured in the striatum. OA significantly attenuated EPS and cognitive impairment induced by haloperidol without affecting its antipsychotic properties. Valbenazine only ameliorated VCM. Also, OA normalised the levels of dopamine and acetylcholine in the striatum which were increased by haloperidol. Furthermore, the increased phosphorylated PKA, extracellular signal-regulated kinase (ERK) and cAMP response element-binding protein (CREB) levels and c-FOS expression level induced by haloperidol were significantly decreased by OA in the striatum. In addition, cataleptic behaviour of haloperidol was reversed by sub-effective dose of H-89 with OA. These results suggest that OA can alleviate EPS and cognitive impairment induced by antipsychotics without interfering with antipsychotic properties via regulating neurotransmitter levels and the PKA signaling pathway in the striatum. Therefore, OA is a potential candidate for treating EPS and cognitive impairment induced by antipsychotics.

Case report on antipsychotic induced catatonia in an incarcerated patient.

Antipsychotic-induced catatonia is an iatrogenic and debilitating adverse reaction, but there is a dearth of recent documented cases. This report describes a 35-year-old incarcerated Korean-American male with a history of unspecified psychosis who presented for antipsychotic induced catatonia after administration of haloperidol decanoate intramuscular (200 mg across the span of 1 week). Neurologic workup was performed including MRI, lumbar puncture, and electroencephalography. Despite an approximate month long hospitalization, benzodiazepine challenge, benztropine trial, and amantadine adjunct, our patient continued to experience bradykinesia, waxy flexibility, and mask-like facies, and was minimally verbally responsive. Several challenges in the treatment of incarcerated individuals at the hospital are highlighted in this case report, including adverse reaction to medication, difficulty of care coordination, and limited access to health records among providers.

Differentiating Between Lithium Tremors and Extrapyramidal Tremors in a Patient on Long-Term Antipsychotics and Lithium Medication.

Tremors are characterized by involuntary rhythmic shaking movement in different regions of the body. Tremors can manifest in various forms and have various causes, including the use of drugs such as lithium and antipsychotic medication. In a clinical setting, it is vital to understand the varieties of tremors presented and administer the appropriate pharmacotherapy needed. We present a case of a patient that has been experiencing fine tremors while on antipsychotics and lithium medication for the past year. We address differentiating the tremors while proposing managing the effects based on their mechanisms of action.

[An effect of antipsychotic and anticholinergic treatment on cognitive function in patients with schizophrenia]. / Vliyanie antipsikhoticheskoi i antikholinergicheskoi terapii na kognitivnye funktsii u bol'nykh shizofreniei.

OBJECTIVE: To reveal the relationships between antipsychotic and anticholinergic drugs and cognitive functions in patients with schizophrenia. MATERIAL AND METHODS: The observational prospective study was conducted at the Bekhterev National Medical Center of Psychiatry and Neurology. The study involved 41 patients (22 men and 19 women) with paranoid schizophrenia, according to ICD 10 criteria, aged 30.12±8.24 years on stable antipsychotic monotherapy or in combination with anticholinergic drug (trihexiphenidyl). Cognitive functions were assessed using the «Brief Assessment of Cognitive Function in Patients with Schizophrenia¼ (BACS) scale, severity of mental state and extrapyramidal disturbances were measured using the «Positive and Negative Syndrome Scale (PANSS) and the Simpson-Angus Scale for Assessment of Extrapyramidal Side Effects (SAS). All examination procedures were performed twice at weeks 2 and 8 of therapy. Patients were divided into 2 groups according to the type of antipsychotic therapy. Twelve patients received first generation antipsychotics (FGAs) (group 1), 29 patients received second generation antipsychotics (SGAs) (group 2). RESULTS: Patients receiving SGAs had a significant decrease in the overall SAS score at week 8 of therapy compared with data at week 2, and there was an improvement in cognitive function, unlike patients receiving FGAs. There were also changes on BACS tests the digit sequencing (V=51.5, p=0.007), token motor task (V=75.5, p=0.007) and Tower of London (V=52, p=0.027) only in patients of group 2. CONCLUSION: The improved tolerance to the drug, as well as cognitive measures, was shown in patients taking SGAs by week 8. Our study confirms the importance of adhering to the minimum effective dose of antipsychotic drugs for the treatment of schizophrenia to prevent cognitive impairment, and to give preference to SGAs in the choice of treatment.

Lithium-induced parkinsonism associated with vocal cord paralysis: an atypical presentation.

Drug-induced parkinsonism has been commonly studied and discussed regarding antipsychotic agents, but lithium-induced parkinsonism should also be considered when patients present with parkinsonian symptoms and chronic lithium use. There are several reports of parkinsonism arising during lithium administration and regressing following its reduction or discontinuation. Our case is, to date, the first case in the literature in which vocal cord paralysis occurred as the first symptom of lithium-induced parkinsonism, contributing to confuse doctors and patients and to delay diagnosis and treatment. In our clinical case prompt withdrawal of lithium and its reintroduction at lower doses led to complete resolution of this disabling clinical presentation. This report emphasizes the importance of careful monitoring of lithium levels, especially in elderly subjects, and the need to consider lithium-induced parkinsonism even when unusual motor symptoms appear in chronic lithium users.

Case series of drug-induced open bite: Extrapyramidal symptoms related to psychotropic medications.

Introduction: Drug-induced open bite is one of the extrapyramidal symptoms with abnormal tonus of muscles and is rarely recognized in dentistry. This is a retrospective case study to investigate clinical characteristics including detailed complaints in patients with drug-induced open bite. Methods: Of the outpatients who first visited the psychosomatic dental clinic at the Tokyo Medical and Dental University Hospital between September 2013 and September 2022, the patients diagnosed with drug-induced open bite were involved in this study. The clinical characteristics including sex, age, detailed complaints, duration of illness, abnormal findings, psychotropic medications, and other medications that were taken at the first examination, psychiatric comorbidities, the duration of psychiatric diseases, and other medical histories were collected retrospectively by reviewing their medical chart. Results: Drug-induced open bite was found in 11 patients [women: 7, men: 4, median of age: 49 (36.5, 53) years old]. Difficulty in eating especially chewing was the major complaint (9/11, 81.6%) with the duration of illness as 48.0 (16.5, 66) months. Various degrees of open bite were observed. While some showed no occlusal contact on frontal teeth, some showed occlusal contact only on the second molars; moreover, the jaw showed a horizontal slide in a few patients. Three cases could be followed up for prognosis; while in one case the drug-induced open bite improved with 6 months of follow-up, two cases did not improve, and one showed extrusion of molars. All of them had psychiatric comorbidities with the most common diagnosis being schizophrenia (n = 5) and depression (n = 5) followed by insomnia (n = 1) and autism spectrum disorder (n = 1) including duplicated diagnosis. Nine patients (81.6%) had been undergoing treatment with antipsychotics of which three patients were also taking antidepressants. Discussion: Although a drug-induced open bite is a rare symptom, prudent medical interviews about symptoms, psychiatric comorbidities, and psychotropic medication history besides oral assessment are necessary to provide a precise diagnosis and appropriate management in collaboration between dentists and psychiatrists.

Antipsychotic-induced akathisia in adults with acute schizophrenia: A systematic review and dose-response meta-analysis.

Antipsychotic-induced akathisia is severely distressing. We aimed to investigate relationships between antipsychotic doses and akathisia risk. We searched for randomised controlled trials that investigated monotherapy of 17 antipsychotics in adults with acute schizophrenia until 06 March 2022. The primary outcome was the number of participants with akathisia, which was analysed with odds ratios (ORs). We applied one-stage random-effects dose-response meta-analyses using restricted cubic splines to model the dose-response relationships. We included 98 studies (343 dose arms, 34,225 participants), most of which were short-term and had low-to-moderate risk of bias. We obtained data on all antipsychotics except clozapine and zotepine. In patients with acute exacerbations of chronic schizophrenia, from moderate to high certainty of evidence, our analysis showed that sertindole and quetiapine carried negligible risks for akathisia across examined doses (flat curves), while most of the other antipsychotics had their risks increase initially with increasing doses and then either plateaued (hyperbolic curves) or continued to rise (monotonic curves), with maximum ORs ranging from 1.76 with 95% Confidence Intervals [1.24, 2.52] for risperidone at 5.4 mg/day to OR 11.92 [5.18, 27.43] for lurasidone at 240 mg/day. We found limited or no data on akathisia risk in patients with predominant negative symptoms, first-episode schizophrenia, or elderly patients. In conclusion, liability of akathisia varies between antipsychotics and is dose-related. The dose-response curves for akathisia in most antipsychotics are either monotonic or hyperbolic, indicating that higher doses carry a greater or equal risk compared to lower doses.

Appearance of extrapyramidal symptoms in adolescent psychiatry patients during COVID-19 infection.

Since the start of the pandemic, there has been an increase in the incidence of psychiatric morbidity among those infected with coronavirus disease 2019 (COVID-19) and those indirectly affected by COVID-19. There has been a considerable increase in the number of individuals with such psychiatric conditions as depression, acute stress disorders, anxiety, and posttraumatic stress disorder (PTSD). About one-third of patients with COVID-19 are reported to have developed short and long-term neuropsychiatric conditions such as delirium, agitation, altered consciousness, hypoxic encephalopathy encephalitis, dysexecutive syndrome, cerebrovascular complications (e.g., stroke), hypoxic encephalopathy, convulsions, neuromuscular dysfunction, demyelinating processes, or parkinsonism through several pathophysiological mechanisms. Nevertheless, as the pandemic progressed, data on neuropsychiatric manifestations implied that the pathologic capacity of COVID-19 and its association with the onset and/or exacerbation of psychiatric morbidity indicate that COVID-19 is potentially related to neuropsychiatric involvement. Patients with existing mental disorders under psychotropic treatment exposed to the COVID-19 infection have been represented by an increased risk of worsened psychiatric symptoms and expanded drug side effects. The present study aimed to describe five pediatric patients with various psychiatric illness that experienced COVID-19 infection and had potentially associated neuropsychiatric involvement, such as exacerbation of underlying psychiatric symptoms and extrapyramidal side effects. To the best of our knowledge, the present study is the first to describe adolescents with COVID-19 infection that presented with a series of manifestations in the form of an increase in extrapyramidal symptoms (EPS)  during exacerbation of underlying psychiatric disease.

The factor structure of extrapyramidal symptoms evaluated using the Drug-Induced Extrapyramidal Symptoms Scale in patients with schizophrenia: Results from the 2016 REAP AP-4 study.

INTRODUCTION: Drug-induced extrapyramidal syndrome (EPS) remains a major problem in clinical psychiatry. This study aimed to examine the factor structure of drug-induced extrapyramidal symptoms observed in patients with schizophrenia and assessed using the Drug-Induced Extrapyramidal Symptoms Scale (DIEPSS). METHODS: The participants were 1478 patients with a diagnosis of schizophrenia whose EPS was assessed using the DIEPSS in India, Indonesia, Japan, Malaysia, and Taiwan in the 2016 REAP AP-4 study. The records of the participants were randomly divided into two subgroups: the first for exploratory factor analysis of the eight DIEPSS items, and the second for confirmatory factor analysis. RESULTS: The factor analysis identified three factors: F1 (gait and bradykinesia), F2 (muscle rigidity and tremor), and F3 (sialorrhea, akathisia, dystonia, and dyskinesia). CONCLUSION: The results suggest that the eight individual items of the DIEPSS could be composed of three different mechanisms: acute parkinsonism observed during action (F1), acute parkinsonism observed at rest (F2), and central dopaminergic mechanisms with pathophysiology other than acute parkinsonism (F3).

Dandy-Walker Syndrome: Delayed Acute Presentation With Unusual Symptoms.

Dandy-Walker syndrome (DWS) is a rare congenital brain malformation defined by the presence of an expanded posterior fossa, full or partial absence of the cerebellar vermis, and a cystic expansion of the fourth ventricle. We report an 18-month-old girl with DWS presenting with atypical clinical manifestations and unusual symptoms. She initially presented with persistent vomiting and abdominal pain for four days, not responding to antiemetic medication. In addition, she was found to have abnormal postural arching of the back, extension of the lower limbs, and neck extension. MRI and CT head suggested Dandy-Walker syndrome with hydrocephalus (the lateral ventricle, third ventricle, and fourth ventricle are all significantly dilated with evidence of trans-ependymal cerebrospinal fluid permeation, severe compression anterior displacement of the brain stem). The patient underwent urgent, lifesaving right sub-occipital craniotomy, evacuation, and decompression of the posterior fossa cyst and external ventricular drain (EVD) insertion along with left supra-tentorial EVD insertion. A series of brain magnetic imaging and CT brain post-procedure studies showed a significant reduction in the size of the ventricular system and mass effect on the brain stem.

Adding pre-emptive anticholinergics to antipsychotics: Is it justified?

Anti-psychotics are the mainstay of treatment for Schizophrenia and psychotic disorders. Historically, anticholinergics have been prescribed to prevent or treat extrapyramidal side effects (EPS) associated with first-generation antipsychotics (FGAs). Even though newer antipsychotics are associated with markedly lower rates of EPS, concurrent anticholinergic use remains high. Use of these medications has potential for long-term side effects, worsening of EPS and poor adherence. We have briefly discussed the limited association between second-generation antipsychotics (SGAs) and EPS, the efficacy of anticholinergics for different types of EPS, and summarized various national and international guidelines on the subject. In conclusion, there is no evidence for prophylactic use of anticholinergics with antipsychotics. Clinicians need to guard against this tendency to be unduly cautious.

Switching Antipsychotic Medications in People with Schizophrenia: A 4-Year Naturalistic Study.

Although generally effective in ameliorating the core manifestations of schizophrenia, antipsychotics (APs) may lead to only suboptimal responses or may be associated with a variety of treatment-related adverse events which require additional treatment strategies. Under such clinical circumstances, switching APs represents a rational treatment option. The present study aimed to identify the variables that predict AP switch and to quantify the frequency of this phenomenon in people with schizophrenia in real-life. A secondary analysis was conducted on the data collected at baseline and at a 4-year follow-up from a large sample of community-dwelling Italian people with schizophrenia. Demographic and clinical variables as well as information about AP treatment were recorded at two time points. Over the 4-year period, 34.9% of the 571 participants switched the AP; in particular, 8.4% of participants switched from first-generation APs (FGAs) to second-generation APs or vice versa, while 8.2% of them switched to clozapine. Logistic regression models showed that combination of APs at baseline was negatively associated with AP switch, while treatment with FGAs and the presence of extrapyramidal symptoms at baseline were associated with AP class switch. Although the aim of the present study was not to assess predictors of clinical relapse in people with schizophrenia, we might speculate that switching APs represents a surrogate indicator of treatment failure in some patients and could lead into relapse, which is a costly aspect of schizophrenia management in both economic and human terms. The sooner such a negative outcome can be predicted and managed, the sooner the treatment can be optimized to avoid it.

Recognition and Treatment Challenges of Acute Clozapine Withdrawal Syndrome: A Case Report.

The limited psychiatric bedspace due to the COVID-19 pandemic and the lack of access to an up-to-date medication regimen delayed the recognition of the diagnosis and treatment for a 40-year-old man with schizoaffective disorder, bipolar type, who traveled from his home city and abruptly discontinued his prescription of clozapine. He developed a cholinergic rebound syndrome including delirium and extrapyramidal symptoms (EPS). The delay included time spent in two different medical hospitals: one awaiting psychiatric bedspace, and secondly, when the patient's cholinergic rebound syndrome was misdiagnosed as acute alcohol withdrawal. Once the etiology was recognized, he was promptly treated with anticholinergic medication (benztropine) and retitrated to his outpatient dose of clozapine leading to the resolution of symptoms including delirium and EPS. This case will discuss the challenges of continuity of care in delirious, psychotic, or otherwise confused patients, including contributions from the COVID-19 pandemic. A medication card or other improvements in medication databases that may reduce delays in treatment are discussed.
