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
Alzheimer's disease psychosis (ADP) produces a significant burden for patients and their care partners, but at present there are no approved treatments for ADP. The lack of approved treatments may be due to the challenges of conducting clinical trials for this disease. This perspective article discusses distinct challenges and proposed solutions of conducting ADP trials involving seven key areas: (1) methods to reduce the variable and sometimes high rates of placebo response that occur for treatments of neuropsychiatric symptoms; (2) the use of combined or updated criteria that provide a precise, consensus definition of ADP; (3) the use of eligibility criteria to help recruit individuals representative of the larger ADP population and overcome the difficulty of recruiting patients with moderate-to-severe ADP; (4) consideration of multiple perspectives and implementation of technology to reduce the variability in the administration and scoring of neuropsychiatric symptom assessments; (5) the use of clinically appropriate, a priori-defined severity thresholds and responder cutoffs; (6) the use of statistical approaches that address absolute effect sizes and a three-tier approach to address the fluctuation of neuropsychiatric symptoms; and (7) the implementation of feasible diagnostic and target-engagement biomarkers as they become available. The goal of these proposed solutions is to improve the evaluation of potential ADP therapies, within the context of randomized, placebo-controlled trials with clinically meaningful endpoints and sustained treatment responses.

Differences in pharmacologic and demographic factors in male and female patients with vascular dementia, Alzheimer's disease, and mixed vascular dementia. FRONTIERS IN DEMENTIA 2023; 2:1137856. [PMID: 39081989 PMCID: PMC11285705 DOI: 10.3389/frdem.2023.1137856] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Accepted: 06/15/2023] [Indexed: 08/02/2024]
Abstract
Background Increasing evidence suggests that demographic and pharmacologic factors may play a significant role in the epidemiology of dementia. Sex differences in prevalence also depend on dementia subtypes, such as Alzheimer's dementia (AD), vascular dementia (VaD), and mixed vascular-Alzheimer's dementia (MVAD). Therefore, studies are needed to investigate sex-specific differences, and identify potential therapeutic targets for both sexes. Methods Data was collected from the Prisma Health-Upstate Alzheimer's registry from 2016 to 2021 for 6,039 VaD patients, 9,290 AD patients, and 412 MVAD patients. A logistic regression was used to determine demographic and pharmacological factors associated with gender differences in patients with VaD, AD, and MVAD. Results In patients with VaD, African Americans (OR = 1.454, 95% CI, 1.257-1.682, p < 0.001) with increasing age (OR = 1.023, 95% CI, 1.017-1.029, p < 0.001), treated with aripiprazole (OR = 4.395, 95% CI, 2.880-6.707, p < 0.001), were associated with females, whereas patients treated with galantamine (OR = 0.228, 95% CI, 0.116-0.449, p < 0.001), memantine (OR = 0.662, 95% CI, 0.590-0.744, p < 0.001), with a history of tobacco (OR = 0.312, 95% CI, 0.278-0.349, p < 0.001), and ETOH (OR = 0.520, 95% CI, 0.452-0.598, p < 0.001) were associated with males. Among AD patients, African Americans (OR = 1.747, 95% CI, 1.486-2.053, p < 0.001), and Hispanics (OR = 3.668, 95% CI, 1.198-11.231, P = 0.023) treated with buspirone (OR = 1.541, 95% CI, 1.265-1.878, p < 0.001), and citalopram (OR = 1.790, 95% CI, 1.527-2.099, p < 0.001), were associated with females, whereas patients treated with memantine (OR = 0.882, 95% CI, 0.799-0.974, p = 0.013), and with a history of tobacco (OR = 0.247, 95% CI, 0.224-0.273, p < 0.001), and ETOH (OR = 0.627, 95% CI, 0.547-0.718, p < 0.001) were associated with male AD patients. In patients with MVAD, rivastigmine (OR = 3.293, 95% CI, 1.131-9.585, p = 0.029), memantine (OR = 2.816, 95% CI, 1.534-5.168, p < 0.001), and risperidone (OR = 10.515, 95% CI, 3.409-32.437, p < 0.001), were associated with females while patients with an increased length of stay (OR = 0.910, 95% CI, 0.828-1.000, p = 0.049), with a history of tobacco (OR = 0.148, 95% CI, 0.086-0.254, p < 0.001) and ETOH use (OR = 0.229, 95% CI, 0.110-0.477, p < 0.001) were more likely to be associated with males. Conclusions Our study revealed gender differences and similarities in the demographic and pharmacological factors of VaD, AD, and MVAD. Prospective studies are needed to determine the role of demographic and pharmacological factors in reducing sex-based disparities among VaD, AD, and MVAD patients.

Abstract
Objective Electronic health record (EHR) systems contain a wealth of clinical data stored as both codified data and free-text narrative notes, covering hundreds of thousands of clinical concepts available for research and clinical care. The complex, massive, heterogeneous, and noisy nature of EHR data imposes significant challenges for feature representation, information extraction, and uncertainty quantification. To address these challenges, we proposed an efficient Aggregated naRrative Codified Health (ARCH) records analysis to generate a large-scale knowledge graph (KG) for a comprehensive set of EHR codified and narrative features. Methods The ARCH algorithm first derives embedding vectors from a co-occurrence matrix of all EHR concepts and then generates cosine similarities along with associated p -values to measure the strength of relatedness between clinical features with statistical certainty quantification. In the final step, ARCH performs a sparse embedding regression to remove indirect linkage between entity pairs. We validated the clinical utility of the ARCH knowledge graph, generated from 12.5 million patients in the Veterans Affairs (VA) healthcare system, through downstream tasks including detecting known relationships between entity pairs, predicting drug side effects, disease phenotyping, as well as sub-typing Alzheimer's disease patients. Results ARCH produces high-quality clinical embeddings and KG for over 60,000 EHR concepts, as visualized in the R-shiny powered web-API (https://celehs.hms.harvard.edu/ARCH/). The ARCH embeddings attained an average area under the ROC curve (AUC) of 0.926 and 0.861 for detecting pairs of similar EHR concepts when the concepts are mapped to codified data and to NLP data; and 0.810 (codified) and 0.843 (NLP) for detecting related pairs. Based on the p -values computed by ARCH, the sensitivity of detecting similar and related entity pairs are 0.906 and 0.888 under false discovery rate (FDR) control of 5%. For detecting drug side effects, the cosine similarity based on the ARCH semantic representations achieved an AUC of 0.723 while the AUC improved to 0.826 after few-shot training via minimizing the loss function on the training data set. Incorporating NLP data substantially improved the ability to detect side effects in the EHR. For example, based on unsupervised ARCH embeddings, the power of detecting drug-side effects pairs when using codified data only was 0.15, much lower than the power of 0.51 when using both codified and NLP concepts. Compared to existing large-scale representation learning methods including PubmedBERT, BioBERT and SAPBERT, ARCH attains the most robust performance and substantially higher accuracy in detecting these relationships. Incorporating ARCH selected features in weakly supervised phenotyping algorithms can improve the robustness of algorithm performance, especially for diseases that benefit from NLP features as supporting evidence. For example, the phenotyping algorithm for depression attained an AUC of 0.927 when using ARCH selected features but only 0.857 when using codified features selected via the KESER network[1]. In addition, embeddings and knowledge graphs generated from the ARCH network were able to cluster AD patients into two subgroups, where the fast progression subgroup had a much higher mortality rate. Conclusions The proposed ARCH algorithm generates large-scale high-quality semantic representations and knowledge graph for both codified and NLP EHR features, useful for a wide range of predictive modeling tasks.

Abstract
Abnormal neuronal and synaptic plasticity occurs in Alzheimer's disease (AD) and depression. The latter, particularly late-life, has been recognized as fundamental in the identification of at-risk prodromal stages of AD. The lack of disease-modifying drugs and the off-label use of antipsychotics and antidepressants for neuropsychiatric symptoms (NPSs) have caused a season of therapeutic inappropriateness. To date, the wealth of clinical trials investigating drugs, diverse for structure and mechanism of action, has failed to provide a cure for all the spectrums of NPSs. Psychedelics in microdosing afford promotion of neurogenesis and synaptic plasticity and, recently, have been considered a revolution for the management of depression endowed with faster action and an improved side effect profile than antidepressants. In the current scenario, therefore, the rapid-acting antidepressant esketamine could represent the first-in-class for treatment of NPSs, and this deserves to be demonstrated with an open-label clinical trial.

Abstract
BACKGROUND Alzheimer's disease (AD) is the most frequent subtype of incurable neurodegenerative dementias and its etiopathology is still not clearly elucidated. OBJECTIVE Outline the ongoing clinical trials (CTs) in the field of AD, in order to find novel master regulators. METHODS We strictly reviewed all scientific reports from Clinicaltrials.gov and PubMed databases from January 2010 to January 2019. The search terms were "Alzheimer's disease" or "dementia" and "medicine" or "drug" or "treatment" and "clinical trials" and "interventions". Manuscripts that met the objective of this study were included for further evaluations. RESULTS Drug candidates have been categorized into two main groups including antibodies, peptides or hormones (such as Ponezumab, Interferon β-1a, Solanezumab, Filgrastim, Levemir, Apidra, and Estrogen), and naturally-derived ingredients or small molecules (such as Paracetamol, Ginkgo, Escitalopram, Simvastatin, Cilostazo, and Ritalin-SR). The majority of natural candidates acted as anti-inflammatory or/and anti-oxidant and antibodies exert their actions via increasing amyloid-beta (Aβ) clearance or decreasing Tau aggregation. Among small molecules, most of them that are present in the last phases act as specific antagonists (Suvorexant, Idalopirdine, Intepirdine, Trazodone, Carvedilol, and Risperidone) or agonists (Dextromethorphan, Resveratrol, Brexpiprazole) and frequently ameliorate cognitive dysfunctions. CONCLUSION The presences of a small number of candidates in the last phase suggest that a large number of candidates have had an undesirable side effect or were unable to pass essential eligibility for future phases. Among successful treatment approaches, clearance of Aβ, recovery of cognitive deficits, and control of acute neuroinflammation are widely chosen. It is predicted that some FDA-approved drugs, such as Paracetamol, Risperidone, Escitalopram, Simvastatin, Cilostazoand, and Ritalin-SR, could also be used in off-label ways for AD. This review improves our ability to recognize novel treatments for AD and suggests approaches for the clinical trial design for this devastating disease in the near future.

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
INTRODUCTION There is a tremendous growing need to address the burden of geriatric psychiatric disorders. Recent developments relevant to geriatric psychiatry have focused on Alzheimer's disease (AD), severe/refractory depression, and cancer/end of life care. AREAS COVERED This is a non-systematic, narrative review (databases and websites for search: PubMed, Google Scholar, Medscape, ClinicalTrials.gov; focusing on the last 6 years), and covers developments in disease-modifying therapies for AD, diagnostic radiotracers for AD, medications for neuropsychiatric symptoms of dementia, ketamine/esketamine, psychedelics, and cannabinoids. EXPERT OPINION The focus of on-going trials of anti-amyloid agents has been on individuals with very early stage AD; several agents are under phase 3 investigation, and aducanumab is under FDA review. Amyloid and tau PET scans have been approved by the FDA to assist in the diagnoses of AD. Promising pharmaceuticals for neuropsychiatric symptoms of dementia include pimavanserin, brexpiprazole, escitalopram, dextromethorphan/quinidine, and lithium. Esketamine, although approved for treatment-resistant depression in general adults, failed to demonstrate efficacy in elderly patients in a phase 3 trial. There is preliminary evidence for benefit of psychedelic-assisted psychotherapy in end-of-life and cancer-related depression/anxiety. Evidence for the use of cannabinoids is currently lacking.

Safety of pharmacologic interventions for neuropsychiatric symptoms in dementia: a systematic review and network meta-analysis. BMC Geriatr 2020; 20:212. [PMID: 32546202 PMCID: PMC7298771 DOI: 10.1186/s12877-020-01607-7] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2020] [Accepted: 06/08/2020] [Indexed: 02/06/2023] Open
Abstract
Background Prescribing trends suggest that pharmacologic alternatives to antipsychotics are gaining in popularity, but randomized trial (RCT) data of their comparative safety is scarce. Our objective was to describe the comparative safety of pharmacologic interventions for treating neuropsychiatric symptoms in dementia. Methods We searched MEDLINE, EMBASE, CENTRAL, CINAHL, and PsycINFO, from inception to May 28, 2019, for studies of pharmacologic interventions used to treat neuropsychiatric symptoms in dementia. Dementia care partners selected fracture risk as our primary outcome. Pairs of reviewers, working independently, conducted all study screening, data abstraction, and risk of bias appraisal. We conducted Bayesian random-effects network meta-analyses (NMAs) using data from RCTs to derive odds ratios (ORs). In secondary analyses, we conducted frequentist random-effects NMAs using data from RCTs and Bayesian three-level hierarchical random-effects NMAs incorporating data from RCTs and non-randomized studies. Results Our systematic review included 209 randomized and non-randomized studies (889,378 persons with dementia). In NMAs of data from randomized trials, there were no increased odds of fracture associated with any intervention in primary analyses; however, data were sparse. We found increased odds of cerebrovascular events associated with antipsychotics (odds ratio [OR] 2.12, 95% credible interval [CrI] 1.29 to 3.62; number needed to harm [NNH] = 99) and increased odds of falls associated with dextromethorphan-quinidine (OR 4.16, 95% CrI 1.47 to 14.22; NNH = 55) compared to placebo in persons with dementia. In a subgroup of persons with Alzheimer disease, antipsychotics were associated with increased odds of fracture compared to anticonvulsants (OR 54.1, 95% CrI 1.15 to 38,300; NNH = 18). In older persons (mean age ≥ 80 years) with dementia, anticonvulsants were associated with increased odds of death compared to placebo (OR 8.36, 95% CrI 1.17 to 203.4; NNH = 35) and antipsychotics were associated with increased odds of death compared to antidepressants (OR 5.28, 95% CrI 1.06 to 3.51; NNH = 47). Conclusion Although antipsychotics were associated with greater harm than antidepressants and anticonvulsants in subgroups of persons with dementia, medications used in lieu of antipsychotics for treating neuropsychiatric symptoms in dementia, such as anticonvulsants and dextromethorphan-quinidine, were also associated with harm. Decision-making concerning treatments prescribed in lieu of antipsychotics should include potential harms. PROSPERO registration CRD42017050130.

Abstract
Along with cognitive decline, 90% of patients with dementia experience behavioral and psychological symptoms of dementia, such as psychosis, aggression, agitation, and depression. Atypical antipsychotics are commonly prescribed off-label to manage certain symptoms, despite warnings from the regulatory agencies regarding the increased risk of mortality associated with their use in elderly patients. Moreover, these compounds display a limited clinical efficacy, mostly owing to the fact that they were developed to treat schizophrenia, a disease characterized by neurobiological deficits. Thus, to improve clinical efficacy, it has been suggested that patients with dementia should be treated with exclusively designed and developed drugs that interact with pharmacologically relevant targets. Within this context, numerous studies have suggested druggable targets that might achieve therapeutically acceptable pharmacological profiles. Based on this, several different drug candidates have been proposed that are being investigated in clinical trials for behavioral and psychological symptoms of dementia. We highlight the recent advances toward the development of therapeutic agents for dementia-related psychosis and agitation/aggression and discuss the relationship between the relevant biological targets and their etiology. In addition, we review the compounds that are in the early stage of development (discovery or preclinical phase) and those that are currently being investigated in clinical trials for dementia-related psychosis and agitation/aggression. We also discuss the mechanism of action of these compounds and their pharmacological utility in patients with dementia.

Abstract
Agitation is a common neuropsychiatric symptom (NPS) in the early and middle stages of Alzheimer's disease (AD) dementia, which is difficult to treat and causes much distress. The U.S. Food and Drug Administration (U.S. FDA) issued black box warnings against the use of antipsychotics in dementia in 2005 and 2008 due to the increased risk of morbidity and mortality, resulting in the reduction in antipsychotic use for treating dementia-related NPS and spurring the quest for safer and more effective pharmacological options. The data favoring the use of citalopram for treating agitation in AD dementia is particularly compelling, and this may be a class effect for all selective serotonin reuptake inhibitors. However, concerns about the cardiac side-effects of citalopram have limited its widespread use for this indication. In this article, available efficacy and safety data for the use of citalopram and escitalopram in treating agitation in AD dementia is reviewed, using a composite case to illustrate key points. Practical recommendations are made to facilitate the use of these medications in routine clinical practice, risk mitigation strategies are discussed and salient issues for future clinical research are emphasized.

Abstract
Behavioral and psychological symptoms associated with dementia are highly prevalent and are associated with an increased risk of institutionalization and mortality. Current pharmacological treatments for these symptoms include cholinesterase inhibitors, antipsychotics, and selective serotonin reuptake inhibitors. When used for treating behavioral and psychological symptoms associated with dementia, they are associated with limited efficacy and/or serious adverse events. As such, there has been extensive research into novel agents with varying mechanisms of action targeting behavioral and psychological symptoms associated with dementia. In this article, we present the results of a comprehensive literature search and review that evaluates current agents that have completed or are currently in clinical trials for treating behavioral and psychological symptoms associated with dementia as a primary outcome. We highlight novel agents from miscellaneous drug classes, such as dextromethorphan/quinidine, bupropion/dextromethorphan, lumateperone, deudextromethorphan/quinidine, methylphenidate and scyllo-inositol, and drugs from various therapeutic classes (including atypical antipsychotics, selective serotonin reuptake inhibitors, and cannabinoids) that have demonstrated promising results and were generally well tolerated. Future research with large appropriately powered studies using validated outcome measures for behavioral and psychological symptoms associated with dementia should be conducted to further establish the clinical utility of these agents.

Abstract
Behavioral and psychological symptoms of dementia (BPSD) occur in approximately 80% of patients who receive a diagnosis of major neurocognitive disorder. Nonpharmacologic strategies are the first-line treatment for BPSD. However, psychotropic medications are often necessary when nonpharmacologic methods are not effective in treating symptoms that are distressing or are causing behaviors that are dangerous to the patient or the patient's caregivers. The article provides a review of evidence-based recommendations for the use of antipsychotics, cognitive enhancers, and serotonin reuptake inhibitors for the treatment of BPSD. Different pharmacologic approaches are demonstrated through 2 patient cases in which nonpharmacologic management was not effective. The severity of BPSD must be weighed against the risks and benefits of pharmacologic intervention in order to implement an optimal medication regimen.

Abstract
Introduction: Antipsychotics are used off label to treat behavioral and psychological symptoms of dementia (BPSD). Due to the emerging data of selective serotonin reuptake inhibitors (SSRIs) for treatment of BPSD, clinicians may choose to use this medication class instead of antipsychotics when pharmacologic therapy is necessary. The objective of this study was to evaluate the prevalence of antipsychotic discontinuation 6 months after SSRI initiation for the treatment of BPSD. Methods: Patients with Alzheimer dementia who were prescribed an antipsychotic and later prescribed an SSRI for BPSD during January 1, 2009, through December 30, 2014, were studied. Exclusion criteria included (1) a dementia diagnosis besides Alzheimer; (2) scheduled benzodiazepines, mood stabilizers, or non-SSRI antidepressant use during the study period; (3) diagnoses of bipolar or psychotic disorders; and (4) diagnosis of delirium during the study period. Patients' age, sex, race, and functional assessment of staging for Alzheimer disease scores were collected. The names, doses, and stop dates of SSRIs and antipsychotics were also recorded. Results: Thirty-six patients were included in the analyses. Overall, antipsychotic use was reduced in 11 patients (30.6%). Ten patients (27.8%) discontinued the antipsychotic, and 1 additional patient had a reduction in dose. When comparing specific SSRIs, 8 (72%) responders were prescribed citalopram, and 15 (60%) nonresponders were prescribed sertraline. Discussion: Approximately 30% of patients with Alzheimer dementia who were prescribed antipsychotics for BPSD were able to discontinue the medication or had a dose reduction after starting SSRI therapy. Most SSRI responders were prescribed citalopram.

Abstract
INTRODUCTION Patients with Parkinson disease (PD) frequently experience visual hallucinations (VH). Visual hallucinations are most often viewed as an adverse effect of antiparkinsonian treatment. Possible treatments for this disturbance include a reduction of antiparkinsonian medications, adding atypical antipsychotics, or cholinesterase inhibitors. Some studies demonstrated that selective serotonin reuptake inhibitors may be an optional treatment for patients experiencing psychosis or agitation in dementia. Currently, there is no standard recommended treatment for VH in patients with PD. We present here our clinical experience with escitalopram (selective serotonin reuptake inhibitor) for treating this disturbance. METHODS Thirteen patients with PD (8 men and 5 women; age range 67-83 years) experiencing VH were openly treated with escitalopram 10 or 15 mg/d as add-on. Efficacy was assessed at baseline, then after 4 and 8 weeks of treatment using Clinical Global Impression-Severity and Clinical Global Impression-Improvement. RESULTS At the end of the 4th week of treatment, of 13 patients, 11 subjects demonstrated improvement, and in only 2 patients were there no changes in their condition. After an additional 4 weeks, 2 of the responders showed very significant improvement, 6 demonstrated much improvement, and 3 patients demonstrated minimal improvement. Only 1 patient showed no change in his condition. One additional patient stopped taking escitalopram after 5 weeks because of an absence of improvement in his state. CONCLUSIONS Escitalopram was well tolerated as treatment of VH in PD patients. This medication could be a promising optional therapy for this disturbance; however, further randomized controlled and bigger studies are necessary.

Abstract
We evaluated the most current evidence regarding the benefits and harms of atypical antipsychotics in adults with dementia. In June 2016, following a protocol developed a priori, we systematically searched several databases for published and unpublished data from randomized controlled trials (RCT), observational studies, and meta-analyses; conducted direct meta-analyses using a random effects model; and graded the quality of evidence according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group. One high-quality meta-analysis and published and unpublished data from 8 RCTs and 12 large observational studies met inclusion criteria. When compared with placebo, aripiprazole, risperidone, and olanzapine but not quetiapine result in modest (standardized mean difference <0.5 standard deviations) improvement in neuropsychiatric symptoms. Aripiprazole, risperidone, quetiapine, and olanzapine are associated with increased odds of acute myocardial infraction, and risperidone and olanzapine are associated with increased odds of hip fracture. Observational studies suggest no differences in all-cause mortality between atypical antipsychotics. Observational studies suggest that atypical antipsychotics are associated with lower risk of all-cause mortality and extrapyramidal symptoms but higher risk of stroke when compared with conventional antipsychotics. To manage agitation in adults with progressive dementia, clinicians may recommend atypical antipsychotics with continuous monitoring of behavioral symptoms, informing patients and their families or caregivers of the significant risk of adverse effects and baseline risk of acute myocardial infraction and bone fractures.

Abstract
Antipsychotic medications are widely used in the management of behavioral and psychological symptoms of dementia. While nonpharmacological interventions should be the first-line treatment for behavioral symptoms of dementia, these are often unfeasible and/or ineffective. Conventional and atypical antipsychotic agents appear to have modest to moderate clinical efficacy in the treatment of these symptoms, though it is unclear which individual agents are most effective. No conclusive evidence exists that any available alternative medications are safer and more effective than antipsychotics. A number of studies have shown an increased risk of mortality associated with antipsychotics in patients with behavioral symptoms of dementia, though the observed risk increase may be partially confounded by illness severity and/or preexisting health determinants. The mechanisms of increased mortality risk are not fully established, but are likely to involve cardiovascular events. It is probable, though not certain, that conventional antipsychotics are associated with a greater number of poor outcomes than atypical antipsychotics. In certain patients with refractory behavioral symptoms, antipsychotics are a viable treatment option. Key considerations for antipsychotic prescribing for this population are published in regulatory guidelines, and include minimization of dosage and duration of treatment, continuous reevaluation of symptoms, and involvement of caregivers.

Abstract
Behavioral and psychological symptoms of dementia (known also as neuropsychiatric symptoms) are essential features of Alzheimer's disease and related dementias. The near universal presence of neuropsychiatric symptoms in dementia (up to 90% of cases) has brought significant attention of clinicians and experts to the field. Non-pharmacological and pharmacological interventions are recommended for various types of neuropsychiatric symptoms. However, most pharmacological interventions for the treatment of behavioral and psychological symptoms of dementia are used off-label in many countries. Cognitive decline and neuropsychiatric symptoms can be linked to alterations in multiple neurotransmitter systems, so modification of abnormalities in specific systems may improve clinical status of patients with neuropsychiatric symptoms. Use of serotonergic compounds (novel particles acting on specific receptors and widely acting drugs) in the treatment of neuropsychiatric symptoms is reviewed.

Abstract
Neuropsychiatric symptoms (NPS) of dementia including agitation, depression, and psychosis are common and debilitating facets of the disease process. Despite the significant impact of these symptoms on both individuals with dementia and their caregivers, safe and effective treatment options are lacking. From a pharmacological approach, antipsychotics have historically been the treatment of choice, but these medications are only modestly effective with significant adverse effects. Behavioral and psychosocial interventions have been shown to be effective but are difficult to implement in routine clinical practice. SSRI medications have been investigated as an alternative psychopharmacological approach based on evidence that the serotoninergic system is involved in the etiology of NPS in dementia. The evidence base for using SSRI medications in the treatment of NPS is growing, but the applicability of research findings to the utility of SSRIs in general in routine clinical practice is not entirely clear at this point. Further studies of a variety of SSRI medications in targeting NPS are needed to make a more definitive assessment of the efficacy of these medications in the relief of NPS.

Abstract
Psychosis is relatively common in later life and can present in a wide variety of contexts, including early-onset and late-onset schizophrenia, delusional disorder, mood disorders, and various dementias. It can also occur as the result of numerous medical and neurological diseases and from the use of certain medications. Although identifying the cause of psychosis in older patients can be challenging, the unique clinical features associated with the different disorders can help in making the diagnosis. Accurate diagnosis of psychosis in older populations is essential, as its treatment varies depending on the context in which it appears. Despite the safety concerns regarding the use of antipsychotics in older patients, certain pharmacological treatments appear to be both efficacious and reasonably safe in treating psychosis in older populations. Additionally, although research is limited, numerous psychosocial therapies appear promising. This review summarizes the literature on the epidemiology, clinical characteristics, neuroimaging, and treatment of psychosis in later life, and serves as an update to past reviews on this topic.

Abstract
Neurocognitive impairment due to Alzheimer's disease (previously termed Alzheimer's dementia) (AD) is the most common form of cognitive impairment worldwide. Given the anticipated increase in the population aged 65 and over, the prevalence of persons with AD is expected to increase exponentially during the next 30 years. Noncognitive neuropsychiatric symptoms (NPS) commonly occur in AD and are associated with adverse outcomes for patients and their caregivers. This review summarizes randomized, controlled trials (RCTs) published between 2004 and 2014 with a primary outcome measure of change in symptom severity for NPS in AD. Of the 388 articles initially identified through a literature search, 33 trials met inclusion criteria. Fifteen of these studies had agitation/aggression as a targeted symptom. Twenty-eight evaluated pharmacologic treatments, including psychotropics, cognitive enhancers, stimulants, and nutraceuticals. Nonpharmacologic interventions included bright light, music, exercise, and cognitive-stimulation therapies. Among the pharmacologic interventions, modest efficacy was reported with aripiprazole, citalopram, trazodone, methylphenidate, and scheduled analgesics. Significant reduction in symptom severity was reported with nearly all the nonpharmacologic interventions. Variations in methodology such as inclusion criteria, study setting, and outcome measures limit the generalizability of these results. Barriers to the implementation of nonpharmacologic interventions in clinical settings include resource and training limitations. Electroconvulsive therapy and dronabinol are promising as emerging treatment strategies. Randomized clinical trials are needed in order to validate the utility of electroconvulsive therapy and dronabinol, including where and with whom these interventions will prove most valuable.

Abstract
Neuropsychiatric symptoms (NPS) are common among individuals with Alzheimer's disease (AD), associated with excess morbidity and mortality, greater healthcare use, earlier institutionalization, and caregiver burden. Agitation presents as emotional distress, excessive psychomotor activity, aggressive behaviors, disruptive irritability and dishibition. There is an unmet need to find pharmacologic treatment for agitation in patients with AD that can be safely and effectively used as a concurrent treatment alongside psychosocial interventions. A recent, multicenter, randomized, placebo-controlled trial explored the efficacy of a 30-mg daily dose of citalopram for agitation in patients with AD and showed a significant decrease in agitation for citalopram compared with placebo. Both QTc prolongation and cognitive worsening, as measured by the Mini Mental State Examination, were observed in the citalopram group and present a concern to clinicians. Citalopram at a 20-mg daily dose should be considered as a possible first-line treatment in addition to psychosocial intervention.

Abstract
Neuropsychiatric symptoms (NPS) are a major concern in the treatment of Alzheimer's disease. Historically, NPS are difficult to treat effectively due to a high side-effect burden associated with commonly used medications, such as atypical antipsychotics. Non-pharmacological treatment approaches have become the first line option. However, when such treatment fails, pharmacological options are often used. Thus, a push toward finding safer alternative pharmacological treatments has occurred. Antidepressants, particularly selective serotonin reuptake inhibitors (SSRIs) have shown promise in clinical trials for alleviating the burden of NPS. Lower overall agitation and caregiver stress has been reported to correlate to treatment with the SSRI citalopram. However, certain side effects of citalopram, such as QTc interval prolongation and increased cognitive decline, carry clinical concern and should be weighed when prescribing their use.

Abstract
BACKGROUND While there have been no new medications approved for the treatment of Alzheimer's disease (AD) or other dementias in Canada since 2004, the Canadian Consensus Conference on the Diagnosis and Treatment of Dementia (CCCDTD) reviewed and updated the clinical practice guidelines on the pharmacological management of dementia that were published previously. METHODS This review focused on the literature for the pharmacological treatment of dementia based on studies published since the third CCCDTD in 2006. A literature search of English-language medical databases was preformed for studies pertaining to the pharmacological treatment of AD and other dementias that examined the management of cognitive and functional impairment, as well as neuropsychiatric symptoms. All previous recommendations were reviewed, and only those that required updating based on new published studies were revised. Several new recommendations were also added. Recommendations were rated for quality of evidence and were approved by consensus. RESULTS There were 15 revised or new recommendations approved by consensus. The revised recommendations included acknowledging that cholinesterase inhibitors (ChEIs) possess a class effect and any of the agents can be used for AD across the spectrum of severity and with co-existing cerebrovascular disease. There was insufficient evidence to recommend for or against the use of ChEIs in combination with memantine for the primary indication of treating neuropsychiatric symptoms, or for the treatment of vascular dementia. Recommendations for the discontinuation of cognitive enhancers were revised and clarified, as well as the risks associated with discontinuing these drugs. ChEIs were recommended as a treatment option for dementia with Parkinson's disease. Risks associated with use of antipsychotics for neuropsychiatric symptoms were strengthened, and guidelines regarding the use of antidepressants for affective disturbances in dementia were weakened, and are now considered an option but not a firm recommendation. Valproate was recommended not to be used, and there was insufficient evidence to recommend for or against the use of selective serotonin reuptake inhibitors or trazodone for the treatment of agitation and aggression. CONCLUSION In spite of the lack of new therapeutic agents for the treatment of dementia, recent studies have helped to clarify and strengthen recommendations to optimize the pharmacological management of these illnesses.

Abstract
BACKGROUND Medications are frequently prescribed for neuropsychiatric symptoms (NPS) associated with dementia, although information on the efficacy and safety of medications for NPS specifically in long-term care (LTC) settings is limited. The objective of this study was to provide a current review of the efficacy and safety of pharmacological treatments for NPS in LTC. METHODS We searched MEDLINE, EMBASE, PsychINFO, and the Cochrane Library for randomized controlled trials comparing medications with either placebo or other interventions in LTC. Study quality was described using the Cochrane collaboration risk of bias tool. The efficacy of medications was evaluated using NPS symptom rating scales. Safety was evaluated through rates of trial withdrawals, trial withdrawals due to adverse events, and mortality. RESULTS A total of 29 studies met inclusion criteria. The most common medications evaluated in studies were atypical antipsychotics (N = 15), typical antipsychotics (N = 7), anticonvulsants (N = 4), and cholinesterase inhibitors (N = 3). Statistically significant improvements in NPS were noted in some studies evaluating risperidone, olanzapine, and single studies of aripiprazole, carbamazepine, estrogen, cyproterone, propranolol, and prazosin. Study quality was difficult to rate in many cases due to incomplete reporting of details. Some studies reported higher rates of trial withdrawals, adverse events, and mortality associated with medications. CONCLUSIONS We conclude that there is limited evidence to support the use of some atypical antipsychotics and other medications for NPS in LTC populations. However, the generally modest efficacy and risks of adverse events highlight the need for the development of safe and effective pharmacological and non-pharmacological interventions for this population.

Abstract
PURPOSE OF REVIEW In this article, we discuss new data on currently licensed drugs for dementia and novel developments in the management of neuropsychiatric symptoms in patients with dementia. RECENT FINDINGS During the last years, a large body of evidence has been accumulated to support the use of antidementia medication in patients with severe Alzheimer's disease. Combination therapy with acetylcholinesterase inhibitors and memantine for Alzheimer's disease remains controversial, as controlled trials have yielded conflicting results. Memantine is not indicated in patients with mild Alzheimer's disease. Studies on memantine for Parkinson's disease dementia and dementia with Lewy bodies were inconclusive. In adult patients with dementia in the context of Down syndrome, memantine is not effective, and further studies on acetylcholinesterase inhibitors are warranted. There is still no treatment established for patients with vascular or frontotemporal dementia. The efficacy of antidepressants to treat depression associated with dementia is not proven. Treatment of agitation and psychosis in patients with dementia remains a challenge. SUMMARY Recent systematic clinical reviews and new research on currently available treatment options provide valuable assistance for clinicians to deal with frequent clinical problems in the context of dementia.

Abstract
Behavioral disturbances are frequently the most challenging manifestations of dementia and are exhibited in almost all people with dementia. Common behavioral disturbances can be grouped into four categories: mood disorders (e.g., depression, apathy, euphoria); sleep disorders (insomnia, hypersomnia, night-day reversal); psychotic symptoms (delusions and hallucinations); and agitation (e.g., pacing, wandering, sexual disinhibition, aggression). They are often persistent, greatly diminish quality of life of patients and their family caregivers, cause premature institutionalization, and pose a high economic burden on the patient, family, and society. Behavioral disturbances can be prevented and treated with a multifaceted approach that supports dignity and promotes comfort and quality of life of persons with dementia and their family members. Management involves prompt treatment of reversible factors and management of symptoms using primarily individualized nonpharmacological interventions. Pharmacological interventions need to be restricted to behavioral emergencies and for short-term treatment of behavioral disturbances that pose imminent danger to self or others.
