Abstract
OBJECTIVE This study aimed to analyze and map scientific literature on Neuroleptic Malignant Syndrome (NMS) and Serotonin Syndrome (SS) from prestigious, internationally indexed journals. The objective was to identify key topics, impactful articles, prominent journals, research output, growth patterns, hotspots, and leading countries in the field, providing valuable insights for scholars, medical students, and international funding agencies. METHODS A systematic search strategy was implemented in the PubMed MeSH database using specific keywords for NMS and SS. The search was conducted in the Scopus database, renowned for its extensive coverage of scholarly publications. Inclusion criteria comprised articles published from 1950 to December 31st, 2022, restricted to journal research and review articles written in English. Data were analyzed using Microsoft Excel for descriptive analysis, and VOSviewer was employed for bibliometric mapping. RESULTS The search yielded 1150 articles on NMS and 587 on SS, with the majority being case reports. Growth patterns revealed a surge in NMS research between 1981 and 1991, while SS research increased notably between 1993 and 1997. Active countries and journals differed between NMS and SS, with psychiatry journals predominating for NMS and pharmacology/toxicology journals for SS. Authorship analysis indicated higher multi-authored articles for NMS. Top impactful articles focused on review articles and pathogenic mechanisms. Research hotspots included antipsychotics and catatonia for NMS, while SS highlighted drug interactions and specific medications like linezolid and tramadol. CONCLUSIONS NMS and SS represent rare but life-threatening conditions, requiring detailed clinical and scientific understanding. Differential diagnosis and management necessitate caution in prescribing medications affecting central serotonin or dopamine systems, with awareness of potential drug interactions. International diagnostic tools and genetic screening tests may aid in safe diagnosis and prevention. Reporting rare cases and utilizing bibliometric analysis enhance knowledge dissemination and research exploration in the field of rare drug-induced medical conditions.

Abstract
Recent randomized controlled trials (RCTs) have shown a benefit of brexpiprazole in managing agitation in patients with Alzheimer's disease (AD). However, its efficacy and safety remain unclear. We systematically searched PubMed, Embase, and Cochrane Library for RCTs comparing brexpiprazole with placebo in patients with agitation and AD. Three studies comprising 1,048 patients were included. In patients with agitation and AD, brexpiprazole significantly improved the Cohen-Mansfield Agitation Inventory total score (CMAI) at any dose (MD -3.05; 95% CI -5.12, -0.98; p < 0.01; I2 = 19%) and at 2 mg (MD -4.36; 95% CI -7.02, -1.70; p < 0.01; I2 = 0%) over 12 weeks. Brexpiprazole at any dose and 2 mg also showed benefit in the Clinical Global Impression - Severity of illness (CGI-S) score as related to agitation over 12 weeks (MD -0.20; 95% CI -0.36, -0.05; p < 0.01; I2 = 35%). There is no significant difference between the groups in the incidence of at least one treatment-emergent adverse events (TEAEs; RR 1.14; 95% CI 0.95, 1.37; p = 0.16; I2 = 45%) and all-cause mortality (RR 1.99; 95% CI 0.37, 10.84; p = 0.42; I2 = 0%). Brexpiprazole at any dose significantly increased the Simpson-Angus Scale (SAS; MD 0.47; 95% CI 0.28, 0.66; p < 0.01). Our results suggest that brexpiprazole is more efficacious than placebo in the treatment of agitation in AD patients. Further studies are still necessary to confirm long-term effects of brexpiprazole.Prospero registry: CRD42023486694.

Abstract
Behavioural and psychological symptoms of dementia (BPSD) are a clinical challenge for the lack of a sound taxonomy, frequent presentation with comorbid BPSD, lack of specific pharmacologic interventions, poor base of methodologically sound evidence with randomized clinical trials, contamination from the treatment of behavioural disturbances of young and adult psychiatric conditions, and small efficacy window of psychotropic drugs. We present here a treatment workflow based on a concept-driven literature review based on the notions that (i) the aetiology of BPSD can be mainly neurobiological (so-called 'primary' symptoms) or mainly environmental and functional ('secondary' symptoms) and that this drives treatment; (ii) the clinical efficacy of psychotropic drugs is driven by their specific profile of receptor affinity; (iii) drug treatment should follow the rules of 'start low-go slow, prescribe and revise'. This article argues in support of the distinction between primary and secondary BPSD, as well as their characteristics, which until now have been just sketchily described in the literature. It also offers comprehensive and pragmatic clinician-oriented recommendations for the treatment of BPSD.

Abstract
Low doses of brexpiprazole (0.5-2 mg per day) have been tried to treat dementia-related psychosis/agitation and Parkinson's disease psychosis. We report a 71-year-old patient with a diagnosis of probable dementia with Lewy body (DLB) whose psychotic symptoms benefit from a higher dose of brexpiprazole (4 mg per day) without adverse effects. Though more studies were needed to confirm the safety and efficacy of brexpiprazole in the treatment of DLB, this case suggests that brexpiprazole is a potential treatment choice and it is safe even at the maximum daily dose (i.e., 4 mg per day).

Abstract
Neurological diseases often manifest with neuropsychiatric symptoms such as depression, emotional incontinence, anger, apathy and fatigue. In addition, affected patients may also experience psychotic symptoms such as hallucinations and delusions. Various factors contribute to the development of psychotic symptoms, and the mechanisms of psychosis are similar, but still differ among various neurological diseases. Although psychotic symptoms are uncommon, and have been less well investigated, they may annoy patients and their families as well as impair the patients' quality of life and increase the caregiver burden. Therefore, we need to appropriately identify and treat these psychotic symptoms in patients with neurological diseases.

Abstract
BACKGROUND AND OBJECTIVES Physicians often face difficulties in selecting appropriate medications for older adults with multiple comorbidities. As people age, they are more likely to be living with a number of chronic conditions (multimorbidity) and be prescribed a high number of medications (polypharmacy). Multimorbidity is frequent in nursing home (NH) residents and the use of potentially inappropriate medications, especially psychotropic drugs, is widespread. This retrospective cross-sectional cohort study examined the frequency of potentially inappropriate psychotropic drugs using the Beers, Screening Tool of Older Persons' Prescriptions/Screening Tool to Alert doctors to Right Treatment (STOPP/START) and Fit fOR The Aged (FORTA) criteria, and their association with mortality. METHODS This retrospective cross-sectional cohort study was conducted on a sample of long-term care NHs across Italy. Of the 34 NHs with an electronic medical records system, 27 met the inclusion criteria, with complete web-based case report forms (CRFs). Residents under the age of 65 years were excluded. We calculated the prevalence of potentially inappropriate psychotropics drugs (antipsychotics, antidepressants and anxiolytics/hypnotics) according to three criteria for prescriptive appropriateness. Univariate and multivariate correlations were examined, taking into account age, sex, comorbidities, and the number of psychotropic drugs, to analyse the relationship between inappropriate psychotropic use and mortality rates. The rate of inappropriate psychotropic prescriptions was calculated with the prevalence of residents receiving potentially inappropriate psychotropic drugs according to the three criteria. We used a logistic model to check for a possible predictive relationship between inappropriate use of psychotropics and mortality. The study evaluated differences in prescriptive appropriateness among NHs by analysing the proportions of potentially inappropriately treated residents at the last visit. Differences were compared with the overall sample mean using confidence intervals (CIs) calculated using Wald's method. RESULTS This study involved 2555 residents, of whom 1908 (74.7% of the total) were treated with psychotropic drugs; 186 (7.3% of the total) were exposed to at least one psychotropic drug considered potentially inappropriate according to the FORTA criteria. Analysis using the Beers criteria showed that 1616 residents (63.2% of the total) received at least one psychotropic drug considered potentially inappropriate. In line with the Beers recommendation, patients receiving at least three psychotropic drugs were also included and 440 were identified (17.2% of the total sample). According to the STOPP criteria, 1451 residents (56.8% of the total sample) were prescribed potentially inappropriate psychotropic drugs. No correlation was found between potentially inappropriate use of psychotropic drugs and mortality, in either univariate analysis or in a multivariate model adjusted for age, sex and comorbidity index. CONCLUSIONS Different criteria for appropriate drug prescription identify very different percentages of patients in NHs exposed to psychotropics considered potentially inappropriate. The Beers and STOPP/START criteria identified a larger percentage of patients exposed in NHs than FORTA.

Risk of long-term care admissions among Medicare beneficiaries treated with pimavanserin or quetiapine for Parkinson's disease psychosis in USA: a retrospective administrative claims database analysis. J Comp Eff Res 2024; 13:e230114. [PMID: 38099518 PMCID: PMC10842290 DOI: 10.57264/cer-2023-0114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 11/22/2023] [Indexed: 01/06/2024] Open
Abstract
Aim: Risk of long-term care (LTC) admission (LTCA) associated with atypical antipsychotic (AAP) use among patients with Parkinson's disease psychosis (PDP) is a major concern. However, no comparative studies have examined the differences in risk of LTC admissions between pimavanserin (PIM), the only FDA-approved AAP for PDP, and other off-label AAPs including quetiapine (QUE). Objective: To examine all-cause LTCA rates and risk among PDP patients treated with AAPs such as QUE or PIM. Methods: Analysis of Parts A, B and D claims (100% Medicare sample; 2013-2019) of Medicare beneficiaries with PDP that initiate ≥12-month continuous PIM or QUE monotherapy from 1 January 2014 to 31 December 2018 (i.e., index date) without any AAP use in the 12-month pre-index period was conducted. Outcome assessments among 1:1 propensity score-matched (31 variables - age, sex, race, region and 27 Elixhauser comorbidities) beneficiaries on PIM versus QUE included risk of all-cause skilled nursing facility stays (SNF-stays), LTC-stays, and overall LTCA (i.e., SNF-stays or LTC-stays). All-cause LTCA rates and LTCA risk were compared using logistic regression and cox proportional hazards models, respectively, controlling for demographics, comorbidities and co-existing-dementia or insomnia. Results: Of the matched sample (n = 842 for each group) from total sample (n = 9652), overall all-cause LTCA and SNF-stay rates were 23.2 and 20.2% for PIM versus 33.8 and 31.4% for QUE, respectively (p < 0.05, for each). Hazard ratio (95% CI) for risk of SNF-stay and overall LTCA was 0.78 (0.61, 0.98) and 0.80 (0.66, 0.97), respectively, for PIM versus QUE beneficiaries (p < 0.05, for each). Conclusion: The 20% lower risk of LTCA (i.e., greater delay) with PIM versus QUE in this analysis may suggest that PIM should be started early for the treatment of PDP.

Abstract
Neuropsychiatric or behavioral symptoms of dementia encompass a series of disorders, such as anxiety, depression, apathy, psychosis, and agitation, all commonly present in individuals living with dementia. While they are not required for the diagnosis of Alzheimer's disease (AD), they are ubiquitously present in all stages of the disease, contributing to negative clinical outcomes, including cognitive decline, functional disability, and caregiver burden. Neuropsychiatric symptoms have been conceptualized not only as risk factors but as clinical markers of decline along the AD spectrum. The concept of "mild behavioral impairment", the behavioral correlate of mild cognitive impairment, has been proposed within this framework. The first steps in the management of behavioral symptoms in AD involve defining the target and investigating potential causes and/or aggravating factors. Once these factors are addressed, non-pharmacological approaches are preferred as first-line interventions. Following the optimization of anticholinesterase treatments, specific pharmacological approaches (e.g., antidepressants, antipsychotics) can be considered weighing potential side effects.

Abstract
The growing prevalence of dementia makes it important for us to better understand its pathophysiology and treatment modalities, to improve the quality of life of patients and caregivers. Alzheimer's disease (AD), a neurodegenerative disease, is the most common form of amnestic dementia in the geriatric population. Pathophysiology of AD is widely attributed to aggregation of amyloid-beta (Aβ) plaques and hyperphosphorylation of tau proteins. Initial treatment modalities aimed to increase brain perfusion in a non-specific manner. Subsequent therapy focused on rectifying neurotransmitter imbalance in the brain. Newer drugs modify the progression of the disease by acting against aggregated Aβ plaques. However, not all drugs used in therapy of AD have been granted approval by the United States Food and Drug Administration (FDA). This review categorizes and summarizes the FDA-approved drugs in the treatment of AD in a manner that would make it a convenient reference for researchers and practicing physicians alike. Drugs that mitigate symptoms of dementia may be categorized into mitigators of Behavioral and Psychological Symptoms of Dementia (BPSD), and mitigators of cognitive decline. BPSD mitigators include brexpiprazole, an atypical antipsychotic with a once-daily dosage suited to treat agitation in dementia patients, and suvorexant, an orexin receptor antagonist used to treat sleep disturbances. Cognitive decline mitigators include cholinesterase inhibitors such as donepezil, rivastigmine, and galantamine and glutamate inhibitors such as memantine. Donepezil is the most commonly prescribed drug. It is cheap, well-tolerated, and may be prescribed orally once daily, or as a transdermal patch once weekly. It increases ACh levels, enhances oligodendrocyte differentiation and also protects against Aβ toxicity. However, regular cardiac monitoring is required due to reports of cardiac conduction side effects. Rivastigmine requires a twice-daily oral dosage or once-daily replacement of transdermal patch. It has fewer cardiac side effects than donepezil, but local application-site reactions have been noted. Galantamine, in addition to improving cognitive symptoms in a short span of time, also delays the development of BPSDs and has minimal drug-drug interactions by virtue of having multiple metabolic pathways. However, cardiac conduction disturbances must be closely monitored for. Memantine, a glutamate regulator, acts as an anti-Parkinsonian agent and an antidepressant, in addition to improving cognition and neuroprotection, and requires a once-daily dosage in the form of immediate-release or sustained-release oral tablets. Disease-modifying drugs such as aducanumab and lecanemab reduce the Aβ burden. Both act by binding with fibrillary conformations of Aβ plaques in the brain. These drugs have a risk of causing amyloid-related imaging abnormalities, especially in persons with ApoE4 gene. Aducanumab is administered once every 4 weeks and lecanemab once every 2 weeks. The decision on the choice of the drug must be made after considering the availability of drug, compliance of patient (once-daily vs. multiple doses daily), cost, specific comorbidities, and the risk-benefit ratio for the particular patient. Other non-pharmacological treatment modalities must also be adopted to have a holistic approach toward the treatment of AD.

Abstract
PURPOSE Because of the common and increasing use of antipsychotics in older adults, we aim to summarize the current knowledge on the causes of antipsychotic-related risk of falls in older adults. We also aim to provide information on the use of antipsychotics in dementia, delirium and insomnia, their adverse effects and an overview of the pharmacokinetic and pharmacodynamic mechanisms associated with antipsychotic use and falls. Finally, we aim to provide information to clinicians for weighing the benefits and harms of (de)prescribing. METHODS A literature search was executed in CINAHL, PubMed and Scopus in March 2022 to identify studies focusing on fall-related adverse effects of the antipsychotic use in older adults. We focused on the antipsychotic use for neuropsychiatric symptoms of dementia, insomnia, and delirium. RESULTS Antipsychotics increase the risk of falls through anticholinergic, orthostatic and extrapyramidal effects, sedation, and adverse effects on cardio- and cerebrovascular system. Practical resources and algorithms are available that guide and assist clinicians in deprescribing antipsychotics without current indication. CONCLUSIONS Deprescribing of antipsychotics should be considered and encouraged in older people at risk of falling, especially when prescribed for neuropsychiatric symptoms of dementia, delirium or insomnia. If antipsychotics are still needed, we recommend that the benefits and harms of antipsychotic use should be reassessed within two to four weeks of prescription. If the use of antipsychotic causes more harm than benefit, the deprescribing process should be started.

METHODS Linkage of administrative claims data from the NSSPP and the Canadian Institute of Health Information Discharge Abstract Database identified LTC residents with an antipsychotic dispensation and from the subgroup of those dispensed antipsychotic medications who experienced a fall-related hospitalization. Antipsychotic dispensing patterns were reported with counts and means. Predictors of continuation of an antipsychotic after a fall-related hospitalization (sex, length of stay, days supplied, age, year of admission, rural/urban) were reported and analyzed with multiple logistic regression. RESULTS There were 19,164 unique NSSPP beneficiaries who were dispensed at least 1 prescription for an antipsychotic medication. Of those who received at least 1 antipsychotic dispensation 90% (n = 17,201) resided in LTC. A mean of 40% (n = 2637) of LTC residents received at least 1 antipsychotic dispensation in each year. Risperidone and quetiapine were dispensed most frequently. Of the 544 beneficiaries residing in LTC who survived a fall-related hospitalization, 439 (80.7%) continued an antipsychotic after hospital discharge. Female sex [OR 1.7, 95% CI (1.013‒2.943)], age 66‒69 [OR 4.587, 95% CI (1.4‒20.8)], 75-79 [OR 2.8, 95% CI (1.3‒6.3)], and 80‒84 years [OR 3.1, 95% CI (1.6‒6.4)] (compared with age 90+ years) were associated with increased risk of antipsychotic continuation. CONCLUSIONS AND IMPLICATIONS With 90% of antipsychotic dispensations in Nova Scotia being to LTC residents and 40% of LTC residents being dispensed antipsychotics in any year there is a need to address this level of antipsychotic dispensation to older adults.

Histone deacetylase inhibitors mitigate antipsychotic risperidone-induced motor side effects in aged mice and in a mouse model of Alzheimer's disease. Front Psychiatry 2023; 13:1020831.

Abstract
Antipsychotic drugs are still widely prescribed to control various severe neuropsychiatric symptoms in the elderly and dementia patients although they are off-label use in the United States. However, clinical practice shows greater side effects and lower efficacy of antipsychotics for this vulnerable population and the mechanisms surrounding this aged-related sensitivity are not well understood. Our previous studies have shown that aging-induced epigenetic alterations may be involved in the increasing severity of typical antipsychotic haloperidol induced side effects in aged mice. Still, it is unknown if similar epigenetic mechanisms extend to atypical antipsychotics, which are most often prescribed to dementia patients combined with severe neuropsychiatric symptoms. In this study, we report that atypical antipsychotic risperidone also causes increased motor side effect behaviors in aged mice and 5xFAD mice. Histone deacetylase (HDAC) inhibitor Valproic Acid and Entinostat can mitigate the risperidone induced motor side effects. We further showed besides D2R, reduced expression of 5-HT2A, one of the primary atypical antipsychotic targets in the striatum of aged mice that are also mitigated by HDAC inhibitors. Finally, we demonstrate that specific histone acetylation mark H3K27 is hypoacetylated at the 5htr2a and Drd2 promoters in aged mice and can be reversed with HDAC inhibitors. Our work here establishes evidence for a mechanism where aging reduces expression of 5-HT2A and D2R, the key atypical antipsychotic drug targets through epigenetic alteration. HDAC inhibitors can restore 5-HT2A and D2R expression in aged mice and decrease the motor side effects in aged and 5xFAD mice.

Abstract
Neuropsychiatric symptoms affect most patients with dementia over the course of the disease. They include a wide variety of symptoms from apathy and depression to psychosis, irritability, impulsivity and agitation. These symptoms are associated with significant distress to the patient and caregivers, as well as more rapid progression of dementia, institutionalisation and higher mortality. The first-line management of the neuropsychiatric symptoms of dementia should be non-pharmacological. If medications are required, antipsychotics are commonly chosen. Second-generation antipsychotics such as risperidone, olanzapine, quetiapine and aripiprazole are prescribed more often than first-generation antipsychotics, such as haloperidol. The aim of this review is to provide an update on findings on adverse outcomes and clinical implications of antipsychotic use in dementia. These medications may increase mortality and can be associated with adverse events including pneumonia, cerebrovascular events, parkinsonian symptoms or higher rates of venous thromboembolism. Risks related to antipsychotic use in dementia are moderated by a number of modifiable and non-modifiable factors such as co-prescribing of other medications, medical and psychiatric co-morbidities, and demographics such as age and sex, making individualised treatment decisions challenging. Antipsychotics have further been associated with an increased risk of reliance on long-term care and institutionalisation, and they might not be cost-effective for healthcare systems. Many of these risks can potentially be mitigated by close physical health monitoring of antipsychotic treatment, as well as early withdrawal of pharmacotherapy when clinically possible.

AMERICAN JOURNAL OF CASE REPORTS 2022; 23:e937397. [PMID: 36282782 PMCID: PMC9619381 DOI: 10.12659/ajcr.937397] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Revised: 09/20/2022] [Accepted: 09/08/2022] [Indexed: 11/04/2023]
Abstract
BACKGROUND Antidopaminergic medications, including antipsychotics, are known to worsen motor and neuropsychiatric symptoms, including cognition and psychosis, in patients with dementia with Lewy body (DLB). The intensity of worsened clinical symptoms may vary and can result in mortality in certain situations. There have been some reports supporting clozapine, quetiapine and pimavanserin use in psychosis control in this population. CASE REPORT We describe the case of 75-year-old man with diagnosis of DLB and the post-treatment outcome with olanzapine for psychosis during hospitalization. He experienced worsened cognitive and motor functions. Discontinuation of olanzapine resulted in resolution of the clinical worsening. Further, re-initiation of Pimavanserin helped treat his hallucinations. He returned back to his baseline during a follow-up visit in the clinic at 1 month after discharge. Further, we incorporated the use of Best Practice Alert (BPA) as a part of the electronic health record (EHR) system to help providers identify patients prone to neuroleptic sensitivity and help select appropriate medications to treat psychosis in this patient population. CONCLUSIONS Administration of antipsychotics in patients with parkinsonism, especially DLB, requires close clinical monitoring and judicious use. Awareness of morbidity and mortality associated with such use is of importance, especially during hospitalization. From our experience, we incorporated use of BPA, which can help providers make judicious choices while treating this patient population. Pimavanserin, which is FDA-approved for psychosis in Parkinson's disease, could be a potential safe and effective treatment option in this patient population.
