Abstract
Neuropsychiatric symptoms (NPS) in Alzheimer's disease (AD) affect up to 97% of AD patients, with an estimated 80% of current AD patients experiencing these symptoms. Common AD-associated NPS include depression, anxiety, agitation, aggression, and apathy. The severity of NPS in AD is typically linked to the disease's progression and the extent of cognitive decline. Additionally, these symptoms are responsible for a significant increase in morbidity, mortality, caregiver burden, earlier nursing home placement, and greater healthcare expenditure. Despite their high prevalence and significant impact, there is a notable lack of clinical research on NPS in AD. In this article, we explore and analyze the prevalence, symptom manifestations, challenges in diagnosis, and treatment options of NPS associated with AD. Our literature review reveals that distinguishing and accurately diagnosing the NPS associated with AD remains a challenging task in clinical settings. It is often difficult to discern whether NPS are secondary to pathophysiological changes from AD or are comorbid psychiatric conditions. Furthermore, the availability of effective pharmaceutical interventions, as well as non-pharmacotherapies for NPS in AD, remains limited. By highlighting the advance and challenges in diagnosis and treatment of AD-associated NPS, we aspire to offer new insights into the complexity of identifying and treating these symptoms within the context of AD, and contribute to a deeper understanding of the multifaceted nature of NPS in AD.

Abstract
Article purpose The clinical approach to Alzheimer's disease (AD) is challenging, particularly in high-functioning individuals. Accurate diagnosis is crucial, especially given the significant side effects, including brain hemorrhage, of newer monoclonal antibodies approved for treating earlier stages of Alzheimer's. Although early treatment is more effective, early diagnosis is also more difficult. Several clinical mimickers of AD exist either separately, or in conjunction with AD pathology, adding to the diagnostic complexity. To illustrate the clinical decision-making process, this study includes de-identified cases and reviews of the underlying etiology and pathology of Alzheimer's and available therapies to exemplify diagnostic and treatment subtleties. Problem The clinical presentation of Alzheimer's is complex and varied. Multiple other primary brain pathologies present with clinical phenotypes that can be difficult to distinguish from AD. Furthermore, Alzheimer's rarely exists in isolation, as almost all patients also show evidence of other primary brain pathologies, including Lewy body disease and argyrophilic grain disease. The phenotype and progression of AD can vary based on the brain regions affected by pathology, the coexistence and severity of other brain pathologies, the presence and severity of systemic comorbidities such as cardiac disease, the common co-occurrence with psychiatric diagnoses, and genetic risk factors. Additionally, symptoms and progression are influenced by an individual's brain reserve and cognitive reserve, as well as the timing of the diagnosis, which depends on the demographics of both the patient and the diagnosing physician, as well as the availability of biomarkers. Methods The optimal clinical and biomarker strategy for accurately diagnosing AD, common neuropathologic co-morbidities and mimickers, and available medication and non-medication-based treatments are discussed. Real-life examples of cognitive loss illustrate the diagnostic and treatment decision-making process as well as illustrative treatment responses. Implications AD is best considered a syndromic disorder, influenced by a multitude of patient and environmental characteristics. Additionally, AD existing alone is a unicorn, as there are nearly always coexisting other brain pathologies. Accurate diagnosis with biomarkers is essential. Treatment response is affected by the variables involved, and the effective treatment of Alzheimer's disease, as well as its prevention, requires an individualized, precision medicine strategy.

Abstract
BACKGROUND An increased risk of manic episodes has been reported in patients with neurodegenerative disorders, but the clinical features of bipolar disorder (BD) in different subtypes of dementia have not been thoroughly investigated. OBJECTIVES The main aim of this study is to systematically review clinical and therapeutic evidence about manic syndromes in patients with Alzheimer's disease (AD), vascular dementia (VaD), and frontotemporal dementia (FTD). Since manic-mixed episodes have been associated to negative outcomes in patients with dementia and often require medical intervention, we also critically summarized selected studies with relevance for the treatment of mania in patients with cognitive decline. METHODS A systematic review of the literature was conducted according to PRISMA guidelines. PubMed, Scopus, and Web of Science databases were searched up to February 2022. Sixty-one articles on patients with AD, VaD, or FTD and BD or (hypo) mania have been included. RESULTS Manic symptoms seem to be associated to disease progression in AD, have a greatly variable temporal relationship with cognitive decline in VaD, and frequently coincide with or precede cognitive impairment in FTD. Overall, mood stabilizers, and electroconvulsive therapy may be the most effective treatments, while the benefits of short-term treatment with antipsychotic agents must be balanced with the associated risks. Importantly, low-dose lithium salts may exert neuroprotective activity in patients with AD. CONCLUSION Prevalence, course, and characteristics of manic syndromes in patients with dementia may be differentially affected by the nature of the underlying neurodegenerative conditions.

Abstract
Medication use can increase the risk of falls and injuries in nursing homes, creating a significant risk for residents. We performed a retrospective cohort study over one year to identify the incidence of drug-related falls with and without injury among four Japanese nursing homes with 280 beds. We evaluated the relationship between potential risk factors for falls and fall-related injuries while considering well-known risks such as ADLs and chronic comorbidities. By collaboratively reviewing care records, we enrolled 459 residents (mean age, 87) and identified 645 falls, including 146 injurious falls and 16 severe injurious falls requiring inpatient care, incidence: 19.5, 4.4, 0.5 per 100 resident-months, respectively. Medication influenced around three-quarters of all falls, >80% of which were psychotropic drugs. Regularly taking ≥5 medications was a risk factor for the initial falls (HR 1.33: CI 1.00−1.77, p = 0.0048) and injuries after falls (OR 2.41: CI 1.30−4.50, p = 0.006). Our findings on the incidence of falls with and without injury were similar to those in Western countries, where the use of psychotropic medication influenced >50% of falls. Discontinuing unnecessary medication use while simultaneously assessing patient ADLs and comorbidities with physicians and pharmacists may help to avoid falls in nursing homes.

Abstract
INTRODUCTION Currently, there are no Food and Drug Administration-approved therapies to treat dementia-related psychosis (DRP). This study investigated the association between using antipsychotics and the anticonvulsant divalproex (sodium valproate) to manage DRP and adverse outcomes. METHODS A retrospective case/control matching study evaluated the risk of mortality, extrapyramidal symptoms (EPS), ischemic stroke, and cardiac arrest/ventricular arrhythmia (CA/VA) with ever-use of antipsychotics/divalproex in patients with DRP vs never-use. RESULTS 49 509 patients were included; 76.8% used an antipsychotic/divalproex. Treatment ever-use was associated with an increased risk of all-cause mortality (odds ratio, 1.14; 95% CI, 1.10-1.18) and a smaller increase in the risk of EPS (1.10; 1.00-1.19) relative to never-use (adjusted for matching demographic variables, comorbid conditions, and disability). CONCLUSIONS Current agents used for DRP were associated with increased risk of death and adverse outcomes. An increased risk of death was evident within 3 months of antipsychotic/divalproex initiation and persisted with long-term use.

Efficacy and safety of pharmacotherapy for Alzheimer's disease and for behavioural and psychological symptoms of dementia in older patients with moderate and severe functional impairments: a systematic review of controlled trials. Alzheimers Res Ther 2021; 13:131.

Abstract
BACKGROUND Many patients with Alzheimer's disease (AD) are physically frail or have substantial functional impairments. There is growing evidence that such patients are at higher risk for medication-induced adverse events. Furthermore, frailty seems to be more predictive of poor clinical outcomes than chronological age alone. To our knowledge, no systematic review of clinical trials examining drug therapy of AD or behavioural and psychological symptoms of dementia (BPSD) has specifically focused on the topic of physical frailty. Our objective was to evaluate the efficacy and safety of pharmacotherapy in AD patients with frailty or significant functional impairments. METHODS We performed a systematic literature search in MEDLINE, Embase and the Cochrane Central Register of Controlled Trials (CENTRAL) for randomized controlled trials (RCTs) of drug therapy of AD and BPSD in patients with significant functional impairments according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement and Cochrane research criteria. Significant functionally impaired patient populations were identified using the recommendations of the Medication and Quality of Life in frail older persons (MedQoL) Research Group. Screening, selection of studies, data extraction and risk of bias assessment were performed independently by two reviewers. Outcomes including functional status, cognitive function, changes in BPSD symptoms, clinical global impression and quality of life were analysed. For assessing harm, we assessed adverse events, drop-outs as a proxy for treatment tolerability and death. Results were analysed according to Cochrane standards and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS Of 45,045 search results, 38,447 abstracts and 187 full texts were screened, and finally, 10 RCTs were included in the systematic review. Selected articles evaluated pharmacotherapy with acetylcholinesterase-inhibitors (AChEI), anticonvulsants, antidepressants and antipsychotics. Studies of AChEIs suggested that patients with significant functional impairments had slight but significant improvements in cognition and that AChEIs were generally well tolerated. Studies of antidepressants did not show significant improvements in depressive symptoms. Antipsychotics and anticonvulsants showed small effects on some BPSD items but also higher rates of adverse events. However, due to the very small number of identified trials, the quality of evidence for all outcomes was low to very low. Overall, the small number of eligible studies demonstrates that significantly functional impaired older patients have not been adequately taken into consideration in most clinical trials investigating drug therapy of AD and BPSD. CONCLUSION Due to lack of evidence, it is not possible to give specific recommendations for drug therapy of AD and BSPD in frail older patients or older patients with significant functional impairments. Therefore, clinical trials focussing on frail older adults are urgently required. A standardized approach to physical frailty in future clinical studies is highly desirable.

Abstract
Objectives: This study evaluated treatment patterns and factors associated with medication treatment changes in residents with dementia-related psychosis in a long-term care (LTC) setting. Methods: A retrospective database cohort study was conducted using the national PharMerica® database and included dementia residents with or without incident psychosis. Treatment patterns were assessed and a multivariate logistic regression model was used to identify factors associated with any treatment change (discontinuation, switch, or sporadic use) in dementia-related psychosis therapy. Results: Among 11,921 residents with incident dementia-related psychosis, 11,246 (94.3%) were prescribed ≥1 index medication to treat psychosis, including 77.3% who received ≥1 typical or atypical antipsychotic. Treatment change was evaluated during the post-index period: 38.7% of residents with dementia-related psychosis discontinued treatment, 13.9% switched treatments, and 7.9% had sporadic use. Factors associated with treatment change were age ≥65 years, Medicare insurance, and comorbid conditions (anemia, coronary heart disease, diabetes, falls, depression, hypertension, or hyperlipidemia) during the pre-index period. Discussion: Approximately 60% of dementia-related psychosis LTC residents experienced a medication treatment change. This treatment change was associated with higher age and higher comorbidities. Medications that treat symptoms of dementia-related psychosis without adding to safety concerns are needed to facilitate long-term, consistent treatment.

Abstract
Objective To determine the risk of hip fracture in persons with Alzheimer´s disease (AD) who initiated antiepileptic drugs (AEDs). Methods In the Medication use and AD (MEDALZ) cohort of 70,719 Finnish community dwellers with clinically verified incident AD diagnosis in 2005-2011, we identified all incident users of AEDs using national Prescription register. AEDs were classified as older (valproate, carbamazepine, clonazepam, phenytoin, levetiracetam, primidone) or newer (pregabalin, gabapentin, oxcarbazepine, lamotrigine, topiramate). We matched each user to 2 non-users. Incident hip fractures until 2015 were identified from the Care register for health care. We calculated inverse probability of treatment weighted hazard ratios (HR), with 95% confidence intervals, using Cox regression. Results Altogether 5522 incident users were identified and matched to 11,044 non-users (in both groups, women: 65%; median age: 81 years). Altogether 53.3% of users initiated with newer AEDs (pregabalin 79.8%, gabapentin 10.2%) while 46.7% initiated with older AEDs (valproate 67.6%, carbamazepine 13.0%). Age- and sex-adjusted IR of hip fracture per 100 person-years was 1.8 (95% CI 1.6-1.9) in non-users and 2.0 (95% CI 1.8-2.2) in users. Increased risk of hip fracture was observed in users (HR 1.17, 95% CI 1.05-1.30) compared with non-users. The risk was higher for short duration of use (<14 weeks, HR 3.64, 95% CI 2.90-4.58) than for medium duration (14 to <64 weeks, HR 1.74, 95% CI 1.48-2.05) or ≥64 weeks' use (HR 1.23, 95% CI 1.08-1.40), compared to non-users with same follow-up time. Older AEDs had HR of 1.46 (1.03-2.08) compared with newer AEDs. Conclusion Our results imply that AED use is associated with an increased risk of hip fracture in people with AD. These findings prompt careful consideration before prescribing AEDs to persons with AD. Persons with AD treated with antiepileptics should be carefully monitored due to their increased risk of falling and fractures.

Abstract
Propionate, a short-chain fatty acid, serves important roles in the human body. However, our review of the current literature suggests that under certain conditions, excess levels of propionate may play a role in Alzheimer's disease (AD). The cause of the excessive levels of propionate may be related to the Bacteroidetes phylum, which are the primary producers of propionate in the human gut. Studies have shown that the relative abundance of the Bacteroidetes phylum is significantly increased in older adults. Other studies have shown that levels of the Bacteroidetes phylum are increased in persons with AD. Studies on the diet, medication use, and propionate metabolism offer additional potential causes. There are many different mechanisms by which excess levels of propionate may lead to AD, such as hyperammonemia. These mechanisms offer potential points for intervention.

Abstract
The core symptoms of different dementia subtypes are the behavioral and psychological symptoms of dementia (BPSD) and its neuropsychiatric symptoms (NPS). BPSD symptoms may occur at any stage in the case of dementia due to Alzheimer's disease (AD), whereas they tend to occur early on in the case of its behavioral variant frontotemporal dementia or dementia with Lewy bodies and are essential for diagnosis. BPSD treatment consists of non-pharmacological as well as pharmacological interventions, with non-pharmacological interactions being suggested as first-line treatment. Agitation, psychotic features, apathy, depression, and anxiety may not respond to acetylcholinesterase inhibitors or memantine in AD cases; therefore, antipsychotics, antidepressants, sedative drugs or anxiolytics, and antiepileptic drugs are typically prescribed. However, such management of BPSD can be complicated by hypersensitivity to antipsychotic drugs, as observed in DLB, and a lack of effective pro-cognitive treatment in the case of frontotemporal dementia. The present paper reviews current knowledge of the management of BPSD and its limitations and discusses on-going clinical trials and future therapeutic options.

Abstract
BACKGROUND Workplace aggression is becoming increasingly prevalent in health care, with serious consequences for both individuals and organisations. Research and development of organisational interventions to prevent and minimise workplace aggression has also increased. However, it is not known if interventions prevent or reduce occupational violence directed towards healthcare workers. OBJECTIVES To assess the effectiveness of organisational interventions that aim to prevent and minimise workplace aggression directed towards healthcare workers by patients and patient advocates. SEARCH METHODS We searched the following electronic databases from inception to 25 May 2019: Cochrane Central Register of Controlled Trials (CENTRAL) (Wiley Online Library); MEDLINE (PubMed); CINAHL (EBSCO); Embase (embase.com); PsycINFO (ProQuest); NIOSHTIC (OSH-UPDATE); NIOSHTIC-2 (OSH-UPDATE); HSELINE (OSH-UPDATE); and CISDOC (OSH-UPDATE). We also searched the ClinicalTrials.gov (www.ClinicalTrials.gov) and the World Health Organization (WHO) trials portals (www.who.int/ictrp/en). SELECTION CRITERIA We included randomised controlled trials (RCTs) or controlled before-and-after studies (CBAs) of any organisational intervention to prevent and minimise verbal or physical aggression directed towards healthcare workers and their peers in their workplace by patients or their advocates. The primary outcome measure was episodes of aggression resulting in no harm, psychological, or physical harm. DATA COLLECTION AND ANALYSIS We used standard Cochrane methods for data collection and analysis. This included independent data extraction and 'Risk of bias' assessment by at least two review authors per included study. We used the Haddon Matrix to categorise interventions aimed at the victim, the vector or the environment of the aggression and whether the intervention was applied before, during or after the event of aggression. We used the random-effects model for the meta-analysis and GRADE to assess the quality of the evidence. MAIN RESULTS We included seven studies. Four studies were conducted in nursing home settings, two studies were conducted in psychiatric wards and one study was conducted in an emergency department. Interventions in two studies focused on prevention of aggression by the vector in the pre-event phase, being 398 nursing home residents and 597 psychiatric patients. The humour therapy in one study in a nursing home setting did not have clear evidence of a reduction of overall aggression (mean difference (MD) 0.17, 95% confidence interval (CI) 0.00 to 0.34; very low-quality evidence). A short-term risk assessment in the other study showed a decreased incidence of aggression (risk ratio (RR) 0.36, 95% CI 0.16 to 0.78; very low-quality evidence) compared to practice as usual. Two studies compared interventions to minimise aggression by the vector in the event phase to practice as usual. In both studies the event was aggression during bathing of nursing home patients. In one study, involving 18 residents, music was played during the bathing period and in the other study, involving 69 residents, either a personalised shower or a towel bath was used. The studies provided low-quality evidence that the interventions may result in a medium-sized reduction of overall aggression (standardised mean difference (SMD -0.49, 95% CI -0.93 to -0.05; 2 studies), and physical aggression (SMD -0.85, 95% CI -1.46 to -0.24; 1 study; very low-quality evidence), but not in verbal aggression (SMD -0.31, 95% CI; -0.89 to 0.27; 1 study; very low-quality evidence). One intervention focused on the vector, the pre-event phase and the event phase. The study compared a two-year culture change programme in a nursing home to practice as usual and involved 101 residents. This study provided very low-quality evidence that the intervention may result in a medium-sized reduction of physical aggression (MD 0.51, 95% CI 0.11 to 0.91), but there was no clear evidence that it reduced verbal aggression (MD 0.76, 95% CI -0.02 to 1.54). Two studies evaluated a multicomponent intervention that focused on the vector (psychiatry patients and emergency department patients), the victim (nursing staff), and the environment during the pre-event and the event phase. The studies included 564 psychiatric staff and 209 emergency department staff. Both studies involved a comprehensive package of actions aimed at preventing violence, managing violence and environmental changes. There was no clear evidence that the psychiatry intervention may result in a reduction of overall aggression (odds ratio (OR) 0.85, 95% CI 0.63 to 1.15; low-quality evidence), compared to the control condition. The emergency department study did not result in a reduction of aggression (MD = 0) but provided insufficient data to test this. AUTHORS' CONCLUSIONS We found very low to low-quality evidence that interventions focused on the vector during the pre-event phase, the event phase or both, may result in a reduction of overall aggression, compared to practice as usual, and we found inconsistent low-quality evidence for multi-component interventions. None of the interventions included the post-event stage. To improve the evidence base, we need more RCT studies, that include the workers as participants and that collect information on the impact of violence on the worker in a range of healthcare settings, but especially in emergency care settings. Consensus on standardised outcomes is urgently needed.

Abstract
The use of psychotropic drugs (antipsychotics, benzodiazepines and benzodiazepine-related drugs, and antidepressants) is common, with a prevalence estimates range of 19-29% among community dwelling older adults. These drugs are often prescribed for off-label use, including neuropsychiatric symptoms. The older adult population also has high rates of pneumonia and some of these cases may be associated with adverse drug events. In this narrative review, we summarize the findings from current observational studies on the association between psychotropic drug use and pneumonia in older adults. In addition to studies assessing the use of psychotropics, we included antiepileptic drugs, as they are also central nervous system-acting drugs, whose use is becoming more common in the aging population. The use of antipsychotics, benzodiazepine, and benzodiazepine-related drugs are associated with increased risk of pneumonia in older adults (≥ 65 years of age), and these findings are not limited to this age group. Minimal and conflicting evidence has been reported on the association between antidepressant drug use and pneumonia, but differences between study populations make it difficult to compare findings. Studies regarding antiepileptic drug use and risk of pneumonia in older persons are lacking, although an increased risk of pneumonia in antiepileptic drug users compared with non-users in persons with Alzheimer's disease has been reported. Tools such as the American Geriatric Society Beers Criteria and the STOPP/START criteria for potentially inappropriate medications aids prescribers to avoid these drugs in order to reduce the risk of adverse drug events. However, risk of pneumonia is not mentioned in the current criteria and more research on this topic is needed, especially in vulnerable populations, such as persons with dementia.

Abstract
Behavioral and psychological symptoms of dementia (BPSD) afflict the vast majority of patients with dementia, especially those with Alzheimer's disease (AD). In clinical settings, patients with BPSD most often do not present with just one symptom. Rather, clusters of symptoms commonly co-occur and can, thus, be grouped into behavioral domains that may ultimately be the result of disruptions in overarching neural circuits. One major BPSD domain routinely identified across patients with AD is the hyperactivity-impulsivity-irritiability-disinhibition-aggression-agitation (HIDA) domain. The HIDA domain represents one of the most difficult sets of symptoms to manage in AD and accounts for much of the burden for caregivers and hospital staff. Although many studies recommend non-pharmacological treatments for HIDA domain symptoms as first-line, they demonstrate little consensus as to what these treatments should be and are often difficult to implement clinically. Certain symptoms within the HIDA domain also do not respond adequately to these treatments, putting patients at risk and necessitating adjunct pharmacological intervention. In this review, we summarize the current literature regarding non-pharmacological and pharmacological interventions for the HIDA domain and provide suggestions for improving treatment. As epigenetic changes due to both aging and AD cause dysfunction in drug-targeted receptors, we propose that HIDA domain treatments could be enhanced by adjunct strategies that modify these epigenetic alterations and, thus, increase efficacy and reduce side effects. To improve the implementation of non-pharmacological approaches in clinical settings, we suggest that issues regarding inadequate resources and guidance for implementation should be addressed. Finally, we propose that increased monitoring of symptom and treatment progression via novel sensor technology and the "DICE" (describe, investigate, create, and evaluate) approach may enhance both pharmacological and non-pharmacological interventions for the HIDA domain.

Abstract
BACKGROUND Behavioral and psychological symptoms of dementia (BPSD) are present in a majority of patients with dementia contributing to increased morbidity, health care costs, and caregiver burden. While there are no United States Food and Drug Administration (FDA)-approved medications for these symptoms, off-label use of medications such as antipsychotics have been shown to have significant adverse effects including increased mortality. The goal of this review is to examine the efficacy and safety of anticonvulsants in the treatment of BPSD. METHODS We will systematically search for randomized trials of anticonvulsants compared to placebo or other treatments such as antidepressants and antipsychotics from the following sources: The Cochrane Library, MEDLINE (OVID SP) in Process and Other Non-Indexed Citations (latest version), EMBASE, clinicalTrials.gov , and the WHO Clinical Trials Registry. The studies will be limited to those published in English but the study location can be worldwide. We will include studies pertaining to individuals with dementia and symptoms of BPSD. The primary outcomes will be behavioral change as measured by validated scales and secondary outcomes will include caregiver burden, quality of life, placement in long term care facility, serious adverse effects, and treatment discontinuation due to adverse effects. Two sets of reviewers will independently screen select and extract data. We will narratively describe the major findings and conclusions from individual studies. Patients who are prescribed antiepileptic drugs (AEDs) for other indications, including seizures, will be excluded. Outcomes of interest will include a change in a validated scale that measures BPSD, serious adverse events, and caregiver quality of life outcomes. If the data are found to be appropriate for a meta-analysis, we will use a random effects model to compute summary estimates of treatment effects. DISCUSSION This is a protocol for a systematic review addressing the anticonvulsant group of medications as a whole, and as such, our results will inform current clinical practice in the use of anticonvulsants for BPSD. It will also help clinicians and policy makers compare the efficacy of anticonvulsants compared to antidepressants and antipsychotics as well as identify areas which will need further study.
