Abstract
BACKGROUND Alzheimer's disease (AD) is characterized by neuropsychiatric symptoms (NPS), which cause great misery to those with dementia and those who care for them and may lead to early institutionalization. OBJECTIVE The present systematic review aims to discuss the various aspects of Alzheimer's, including treatment options. METHODS The databases Embase, PubMed, and Web of Science were searched to collect data. RESULTS Incipient cognitive deterioration is commonly accompanied by these early warning signals of neurocognitive diseases. The neurobiology of NPSs in Alzheimer's disease, as well as particular symptoms, including psychosis, agitation, apathy, sadness, and sleep disorders, will be examined in this review. For NPSs in Alzheimer's disease, clinical trial designs, as well as regulatory issues, were also addressed. A fresh wave of research, however, is helping to push the discipline ahead. For medication development and repurposing, we highlight the most recent results in genetics, neuroimaging, and neurobiology. Even though identifying and treating psychosis in adults with dementia is still a challenging endeavor, new options are coming up that give the field fresh focus and hope. Conclsuion: It can be concluded from the complete literature survey that Alzheimer's-related psychosis as well as other symptoms that are not psychotic, have made significant progress in the last decade. These milestones in the development of safer, more effective treatments have been achieved as a consequence of great focus on non-pharmacological interventions like DICE or WHELD; the investigation into ways to improve existing drugs like aripiprazole, risperidone, amisulpride, and Escitalopram for safer precision-based treatment; and the development of a clinical trial program for pimavanserin.

Abstract
Antipsychotics increase the risk of death in elderly patients with Alzheimer's disease (AD). Thus, there is an immediate need for novel therapies to treat comorbid psychosis in AD. Psychosis has been attributed to a dysregulation of the dopamine system and is associated with aberrant regulation by the hippocampus. Given that the hippocampus is a key site of pathology in AD, we posit that aberrant regulation of the dopamine system may contribute to comorbid psychosis in AD. A ferrous amyloid buthionine (FAB) rodent model was used to model a sporadic form of AD. FAB rats displayed functional hippocampal alterations, which were accompanied by decreases in spontaneous, low-frequency oscillations and increases in the firing rates of putative pyramidal neurons. Additionally, FAB rats exhibited increases in dopamine neuron population activity and augmented responses to the locomotor-inducing effects of MK-801, as is consistent with rodent models of psychosis-like symptomatology. Further, working memory deficits in the Y-maze, consistent with an AD-like phenotype, were observed in FAB rats. These data suggest that the aberrant hippocampal activity observed in AD may contribute to dopamine-dependent psychosis, and that the FAB model may be useful for the investigation of comorbid psychosis related to AD. Understanding the pathophysiology that leads to comorbid psychosis in AD will ultimately lead to the discovery of novel targets for the treatment of this disease.

Abstract
Psychosis and hyperactive behaviors, such as agitation and wandering, affect a significant proportion of patients with Alzheimer's disease (AD). These symptoms are often treated with antipsychotics, usually in an off-label approach. This mini-review provides an updated perspective on the pharmacological approach for the neuropsychiatric symptoms (NPS) in AD. The results of new studies have provided a better understanding of AD-related NPS management, but high-quality evidence still needs to be obtained. Herein, we argue for a more cautious approach to the use of antipsychotics in AD and highlight the importance of exploring alternative treatments for NPS. By doing so, we can ensure that patients with AD receive optimal care that is both effective and safe.

Abstract
INTRODUCTION The first cases of COVID-19 in Israel were reported in February 2020. Family visits were prohibited from March 10, 2020, and then allowed on a limited basis on April 20, 2020. This article examines how COVID-19 impacted long-term care residents and their family members from the perspective of long-term care facility (LTCF) administrative staff. METHODS An online survey was sent to Israeli LTCF administrators between mid-July and mid-October 2020, resulting in 52 completed questionnaires. Quantitative analysis involved descriptive statistics using SPSS, with differences compared via t tests, ANOVA, and χ2 tests. Qualitative analysis involved thematic analysis of responses to open-ended questions. RESULTS COVID-19 was reported to have multiple types of negative impact on residents, including direct effects on morbidity and mortality as well as indirect effects manifested as negative reactions to measures aimed at limiting infection, including isolation from relatives, decreased activities for residents, and COVID-19 testing. The impact of isolation on LTCF residents was reported as negative or very negative by over three-quarters of the respondents. Behavioral problems among residents increased in 32% of the facilities. The qualitative results suggested that adverse effects on residents and family members were partially mitigated by the use of communication technologies. DISCUSSION/CONCLUSION The interplay of multiple factors affected LTCF residents against the backdrop of COVID-19 restrictions. The emergence of mitigating factors which provide solutions to some of the challenges has the potential of improving quality of care for LTCF residents as the pandemic continues and thereafter.

Abstract
Psychosis is a common and distressing symptom in people with Alzheimer disease, and few safe and effective treatments are available. However, new approaches to symptom assessment and treatment are beginning to drive the field forward. New nosological perspectives have been provided by incorporating the emergence of psychotic symptoms in older adults - even in advance of dementia - into epidemiological and neurobiological frameworks as well as into diagnostic and research criteria such as the International Psychogeriatric Association criteria for psychosis in neurocognitive disorders, the Alzheimer's Association International Society to Advance Alzheimer's Research and Treatment (ISTAART) research criteria for psychosis in neurodegenerative disease, and the ISTAART criteria for mild behavioural impairment. Here, we highlight the latest findings in genomics, neuroimaging and neurobiology that are informing approaches to drug discovery and repurposing. Current pharmacological and non-pharmacological treatment options are discussed, with a focus on safety and precision medicine. We also explore trial data for pimavanserin, a novel agent that shows promise for the treatment of psychosis in people with dementia, and discuss existing agents that might be useful but need further exploration such as escitalopram, lithium, cholinesterase inhibitors and vitamin D. Although the assessment and management of psychosis in people with dementia remain challenging, new opportunities are providing direction and hope to the field.

Abstract
Agitation is a behavioral syndrome characterized by increased, often undirected, motor activity, restlessness, aggressiveness, and emotional distress. According to several observations, agitation prevalence ranges from 30 to 50% in Alzheimer's disease, 30% in dementia with Lewy bodies, 40% in frontotemporal dementia, and 40% in vascular dementia (VaD). With an overall prevalence of about 30%, agitation is the third most common neuropsychiatric symptoms (NPS) in dementia, after apathy and depression, and it is even more frequent (80%) in residents of nursing homes. The pathophysiological mechanism underlying agitation is represented by a frontal lobe dysfunction, mostly involving the anterior cingulate cortex (ACC) and the orbitofrontal cortex (OFC), respectively, meaningful in selecting the salient stimuli and subsequent decision-making and behavioral reactions. Furthermore, increased sensitivity to noradrenergic signaling has been observed, possibly due to a frontal lobe up-regulation of adrenergic receptors, as a reaction to the depletion of noradrenergic neurons within the locus coeruleus (LC). Indeed, LC neurons mainly project toward the OFC and ACC. These observations may explain the abnormal reactivity to weak stimuli and the global arousal found in many patients who have dementia. Furthermore, agitation can be precipitated by several factors, e.g., the sunset or low lighted environments as in the sundown syndrome, hospitalization, the admission to nursing residencies, or changes in pharmacological regimens. In recent days, the global pandemic has increased agitation incidence among dementia patients and generated higher distress levels in patients and caregivers. Hence, given the increasing presence of this condition and its related burden on society and the health system, the present point of view aims at providing an extensive guide to facilitate the identification, prevention, and management of acute and chronic agitation in dementia patients.

Abstract
We assessed psychotropic prescribing patterns in the clinical treatment of agitation and aggressive behavior in patients with Alzheimer's disease (AD) treated at specialist outpatient clinics in the Federal District of Brazil. This was a naturalistic, observational, multicenter study of a convenience sample of patients with AD (according to DSM-5) who had behavioral symptoms of aggression and/or agitation at outpatient visits, as assessed by the Neuropsychiatric Inventory (NPI), and required pharmacologic intervention. Participants were recruited in 2018-2019 from 11 AD treatment centers. Sociodemographic and clinical data were collected during routine visits. The sample consisted of 369 older adults with a mean age of 82.3 (SD, 7.7) years. The medications most commonly used in patients with behavioral disorders were antidepressants (79.1%), antipsychotics (70.2%), benzodiazepines (10.6%), and mood stabilizers (9.5%). Quetiapine was the most frequently prescribed antipsychotic medication (48.5%), at a mean dose of 57.4 (SD, 40.7) mg. Citalopram was the most widely used antidepressant medication (32.0%), at a mean daily dose of 24.1 (SD, 8.1) mg. In this sample, two or more pharmacologic agents were frequently used together to control aggression and agitation. Benzodiazepine was not frequently used.

Abstract
Purpose
The impact of COVID-19 has most dramatically affected the older population, and nursing homes have become infection hotspots. As a response, governments have ordered isolation of older adults in geriatric institutions owing to the high risk of critical illness and mortality. The purpose of this paper is to discuss the potential impact of current policies on nursing homes and community-based care and provide suggestions for improvement in care.
Design/methodology/approach
Taking the situation in Israel as an example, the author discussed major systemic problems pertaining to long-term care facilities and to community based care; the neglect of mental health; systemic deficiencies in end of life care; and the need to revise communications concerning COVID-19.
Findings
Within each of the identified areas, recommended changes in strategy, policy and practice can help mitigate the dramatic impact of COVID-19 on the living experience of the older population.
Originality/value
Drawing on the Israeli experience, this paper presents current shortcomings in the policy response to COVID-19 regarding nursing homes and community-based care and provides recommendations that are applicable to other contexts as well. Although some of these have been suggested or even practiced in some locations, many continue to be neglected and have not been discussed even as COVID-19 continues to infect societies around the globe.

Abstract
BACKGROUND Few studies have examined patient characteristics and treatment patterns among patients with dementia and agitation in the United States (US). OBJECTIVE To examine real-world treatment patterns and characteristics of patients with agitation related to dementia who were treated with antipsychotics in US residential care and community-based settings. METHODS This retrospective chart review collected US physician-level data from patients 55 to 90 years old initiated on an antipsychotic medication for the treatment of agitation related to dementia from January 2018 to May 2018. Clinical characteristics and treatment patterns were assessed overall and stratified by residential care and community-based settings. RESULTS A total of 313 participating physicians, 59.5% of whom were primary care physicians, abstracted 801 patient charts (residential care: n = 312; community-based: n = 489). Of patients with agitation who were initiated on an antipsychotic, most patients (74.5%) were initiated within 3 months of the onset of their studied agitation episode, and 62.8% experienced multiple agitation episodes before initiation. While non-pharmacological therapies are recommended first-line approach for agitation in dementia, use of non-pharmacological therapy before initiation of antipsychotics was reported for only 37.8% of patients in residential care and 21.3% in community-based settings. CONCLUSION Most patients were initiated on an antipsychotic treatment after multiple episodes of agitation and largely without initial non-pharmacological therapy, suggesting that current treatment guideline recommendations for first-line non-pharmacological intervention may not be adequately followed in clinical practice. Understanding the clinical burden and treatment patterns among dementia patients with agitation is imperative for effective disease management.

Abstract
BACKGROUND Stroke/thromboembolic events, infections, and death are all significantly increased by antipsychotics in dementia but little is known about why they can be harmful. Using a novel application of a drug repurposing paradigm, we aimed to identify potential mechanisms underlying adverse events. METHODS Whole transcriptome signatures were generated for SH-SY5Y cells treated with amisulpride, risperidone, and volinanserin using RNA sequencing. Bioinformatic analysis was performed that scored the association between antipsychotic signatures and expression data from 415,252 samples in the National Center for Biotechnology Information Gene Expression Omnibus (NCBI GEO) repository. RESULTS Atherosclerosis, venous thromboembolism, and influenza NCBI GEO-derived samples scored positively against antipsychotic signatures. Pathways enriched in antipsychotic signatures were linked to the cardiovascular and immune systems (eg, brain derived neurotrophic factor [BDNF], platelet derived growth factor receptor [PDGFR]-beta, tumor necrosis factor [TNF], transforming growth factor [TGF]-beta, selenoamino acid metabolism, and influenza infection). CONCLUSIONS These findings for the first time mechanistically link antipsychotics to specific cardiovascular and infectious diseases which are known side effects of their use in dementia, providing new information to explain related adverse events.

Abstract
Behavioral and psychological symptoms of dementia are symptoms of disturbed perception, mood, behavior, and thought content that occurred frequently. These symptoms, which include apathy, depression, anxiety, psychosis, agitation, and aggression, can serve as predictors of and early clinical diagnostic markers for Alzheimer's disease (AD) and are common precipitants of institutional care. Agitation and psychosis are associated with accelerated disease progression and increased tau phosphorylation in patients with AD. Current guidelines recommend the use of second-generation antipsychotics for the treatment of agitation and psychosis in AD, but only after first-line non-pharmacological interventions and for no longer than 12 weeks because long-term use of these drugs is associated with an increased risk of mortality and an increased frequency of cerebrovascular events. Therefore, new antipsychotic drugs with improved efficacy and safety are needed as an alternative to current antipsychotic drugs. In this report, we discuss some of the most relevant advances in the field of agitation and psychosis in AD and focus on the recent positive clinical evidence observed with two new antipsychotics drugs: brexpiprazole and pimavanserin. Brexpiprazole is a receptor partial agonist (D2, D3, 5-HT1A), receptor antagonist (5-HT2A/B, α1B/α2C) according to the neuroscience-based nomenclature. Two recent phase III clinical trials have shown that brexpiprazole 2 mg/day is effective for the treatment of agitation in patients with AD and has an improved tolerability and safety profile compared with currently available second-generation antipsychotics. Pimavanserin is a receptor antagonist (5-HT2A, 5-HT2C) that has been given market authorization for psychosis occurring in Parkinson's disease. Recent phase II studies suggest that this drug is effective in AD patients with more severe psychosis, although further long-term studies are needed to better define the efficacy and long-term safety profile of pimavanserin for the treatment of psychosis in AD.

Millan MJ, Dekeyne A, Gobert A, Brocco M, Mannoury la Cour C, Ortuno JC, Watson D, Fone KCF. Dual-acting agents for improving cognition and real-world function in Alzheimer's disease: Focus on 5-HT6 and D3 receptors as hubs. Neuropharmacology 2020; 177:108099. [PMID: 32525060 DOI: 10.1016/j.neuropharm.2020.108099] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2020] [Revised: 04/02/2020] [Accepted: 04/03/2020] [Indexed: 01/01/2023]
Abstract
To date, there are no interventions that impede the inexorable progression of Alzheimer's disease (AD), and currently-available drugs cholinesterase (AChE) inhibitors and the N-Methyl-d-Aspartate receptor antagonist, memantine, offer only modest symptomatic benefit. Moreover, a range of mechanistically-diverse agents (glutamatergic, histaminergic, monoaminergic, cholinergic) have disappointed in clinical trials, alone and/or in association with AChE inhibitors. This includes serotonin (5-HT) receptor-6 antagonists, despite compelling preclinical observations in rodents and primates suggesting a positive influence on cognition. The emphasis has so far been on high selectivity. However, for a multi-factorial disorder like idiopathic AD, 5-HT6 antagonists possessing additional pharmacological actions might be more effective, by analogy to "multi-target" antipsychotics. Based on this notion, drug discovery programmes have coupled 5-HT6 blockade to 5-HT4 agonism and inhibition of AchE. Further, combined 5-HT6/dopamine D3 receptor (D3) antagonists are of especial interest since D3 blockade mirrors 5-HT6 antagonism in exerting broad-based pro-cognitive properties in animals. Moreover, 5-HT6 and dopamine D3 antagonists promote neurocognition and social cognition via both distinctive and convergent actions expressed mainly in frontal cortex, including suppression of mTOR over-activation and reinforcement of cholinergic and glutamatergic transmission. In addition, 5-HT6 blockade affords potential anti-anxiety, anti-depressive and anti-epileptic properties, and antagonising 5-HT6 receptors may be associated with neuroprotective ("disease-modifying") properties. Finally D3 antagonism may counter psychotic episodes and D3 receptors themselves offer a promising hub for multi-target agents. The present article reviews the status of "R and D" into multi-target 5-HT6 and D3 ligands for improved treatment of AD and other neurodegenerative disorders of aging. This article is part of the special issue entitled 'Serotonin Research: Crossing Scales and Boundaries'.

Psychosis-associated DNA methylomic variation in Alzheimer's disease cortex. Neurobiol Aging 2020; 89:83-88.

Abstract
Psychotic symptoms are a common and debilitating feature of Alzheimer's disease (AD) and are associated with a more rapid course of decline. Current evidence from postmortem and neuroimaging studies implicates frontal, temporal, and parietal lobes, with reported disruptions in monoaminergic pathways. However, the molecular mechanisms underlying this remain unclear. In the present study, we investigated methylomic variation associated with AD psychosis in 3 key brain regions implicated in the etiology of psychosis (prefrontal cortex, entorhinal cortex, and superior temporal gyrus) in postmortem brain samples from 29 AD donors with psychosis and 18 matched AD donors without psychosis. We identified psychosis-associated methylomic changes in a number of loci, with these genes being enriched in known schizophrenia-associated genetic and epigenetic variants. One of these known loci resided in the AS3MT gene-previously implicated in schizophrenia in a large GWAS meta-analysis. We used bisulfite-pyrosequencing to confirm hypomethylation across 4 neighboring CpG sites in the ASM3T gene. Finally, our regional analysis nominated multiple CpG sites in TBX15 and WT1, which are genes that have been previously implicated in AD. Thus one potential implication from our study is whether psychosis-associated variation drives reported associations in AD case-control studies.

Abstract
OBJECTIVES Behaviours associated with agitation are common in people living with dementia. The Cohen-Mansfield Agitation Inventory (CMAI) is a 29-item scale widely used to assess agitation completed by a proxy (family carer or staff member). However, proxy informants introduce possible reporting bias when blinding to the treatment arm is not possible, and potential accuracy issues due to irregular contact between the proxy and the person with dementia over the reporting period. An observational measure completed by a blinded researcher may address these issues, but no agitation measures with comparable items exist. DESIGN Development and validation of an observational version of the CMAI (CMAI-O), to assess its validity as an alternative or complementary measure of agitation. SETTING Fifty care homes in England. PARTICIPANTS Residents (N = 726) with dementia. MEASUREMENTS Two observational measures (CMAI-O and PAS) were completed by an independent researcher. Measures of agitation, functional status, and neuropsychiatric symptoms were completed with staff proxies. RESULTS The CMAI-O showed adequate internal consistency (α = .61), criterion validity with the PAS (r = .79, p = < .001), incremental validity in predicting quality of life beyond the Functional Assessment Staging of Alzheimer's disease (β = 1.83, p < .001 at baseline) and discriminant validity from the Neuropsychiatric Inventory Apathy subscale (r = .004, p = .902). CONCLUSIONS The CMAI-O is a promising research tool for independently measuring agitation in people with dementia in care homes. Its use alongside the CMAI could provide a more robust understanding of agitation amongst residents with dementia.

Abstract
According to the World Alzheimer’s report, dementia was estimated to affect 50 million worldwide in 2018, number expected to increase to more than 150 million within 30 years. Alzheimer’s disease is the most common type of dementia, accounting on its own for 2/3 of all dementia cases. The initial signs and symptoms of Alzheimer’s disease relate to progressive cognitive decline, inexorably progressing until the loss of independence. Neuropsychiatric and behavioral symptoms may occur during the progression of the disease; around 20% of patients without any behavioral symptoms at the diagnosis will experience some of them within 2 years. Consequences are early institutionalization, lower quality of life, of both patients and carers, and more severe cognitive impairment. Treatment options for behavioral symptoms include pharmacological and non-pharmacological approaches. The latter are usually preferred, since antipsychotic therapy is not free from several, and often serious, adverse events. However, behavioral symptoms are not always controllable with non-pharmacological intervention. The psychotropic class of medication more frequently prescribed for behavioral symptoms are atypical antipsychotics; among them, risperidone is the only one licensed for the treatment of aggression, in Europe but not in the USA. On that regard, the use of antipsychotic drugs should be limited, due to the increased risk of mortality, stroke, hallucination, and higher risk of relapse after discontinuation. Some new agents are under evaluation, such as pimavanserin and lumateperone. In this review, we are evaluating the current available pharmacological options to treat behavioral symptoms as well as the forthcoming new agents.

Abstract
Psychosis (delusions or hallucinations) in Alzheimer's disease (AD + P) occurs in up to 50% of individuals and is associated with significantly worse clinical outcomes. Atypical antipsychotics, first developed for schizophrenia, are commonly used in AD + P, suggesting shared mechanisms. Despite this implication, little empirical research has been conducted to examine whether there are mechanistic similarities between AD + P and schizophrenia. In this study, we tested whether polygenic risk score (PRS) for schizophrenia was associated with AD + P. Schizophrenia PRS was calculated using Psychiatric Genomics Consortium data at ten GWAS p value thresholds (PT) in 3111 AD cases from 11 cohort studies characterized for psychosis using validated, standardized tools. Association between PRS and AD + P status was tested by logistic regression in each cohort individually and the results meta-analyzed. The schizophrenia PRS was associated with AD + P at an optimum PT of 0.01. The strongest association was for delusions where a one standard deviation increase in PRS was associated with a 1.18-fold increased risk (95% CI: 1.06-1.3; p = 0.001). These new findings point towards psychosis in AD-and particularly delusions-sharing some genetic liability with schizophrenia and support a transdiagnostic view of psychotic symptoms across the lifespan.

Abstract
Fake bus stops are one strategy to keep persons with dementia (PwD) from wandering. By setting up authentic looking shelters and benches in hallways or gardens, nursing homes create the illusion of bus stops, for the purpose of preventing wandering PwD from leaving the facility and getting lost. By attracting wandering PwD to sit down and wait for the bus, they can be supervised more easily by caregivers. However, concerns are expressed that the use of fake bus stops could cause more harm than good for PwD, due to their deceptive nature and the potential stigmatisation of individuals seated at a fake bus stop. This article discusses the ethical aspects of using fake bus stops and outlines considerations prior to setting up fake bus stops in nursing homes in keeping with good clinical practice in dementia care. Moreover, the article assesses whether or not fake bus stops can be ethically justifiable, and if so, how they can be ethically justified and implemented in Israeli and other facilities for PwD.
