Abstract
OBJECTIVE Lewy body dementia (LBD) is the second most common neurodegenerative dementia, and it causes earlier mortality and more morbidity than Alzheimer's disease. Reviewing current evidence on its pharmacological management is essential for developing evidence-based clinical guidelines, and for improving the quality of its clinical care. Hence, we systematically reviewed all studies that investigated the efficacy of any medication for managing various symptoms of LBD. METHOD We identified eligible studies by searching 15 databases comprehensively. We completed quality assessment, extracted relevant data, and performed GRADE assessment of available evidence. We conducted meta-analyses when appropriate (PROSPERO:CRD42020182166). RESULTS We screened 18,884 papers and included 135 studies. Our meta-analyses confirmed level-1 evidence for Donepezil's efficacy of managing cognitive symptoms of dementia with Lewy bodies (DLB) (SMD = 0.63; p < 0.001) and Parkinson's Disease Dementia (PDD) (SMD = 0.43; p < 0.01), and managing hallucinations in DLB (SMD=-0.52; p = 0.02). Rivastigmine and Memantine have level-2 evidence for managing cognitive and neuropsychiatric symptoms of DLB. Olanzapine and Yokukansan have similar evidence for managing DLB neuropsychiatric symptoms. Level-2 evidence support the efficacy of Rivastigmine and Galantamine for managing cognitive and neuropsychiatric symptoms of PDD. CONCLUSION We list evidence-based recommendations for the pharmacological management of DLB and PDD, and propose specific clinical guidelines for improving their clinical management.

A protocol for a think-aloud study informing the value of care. Front Aging Neurosci 2022; 14:1061247. [PMID: 36589541 PMCID: PMC9800871 DOI: 10.3389/fnagi.2022.1061247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Accepted: 12/02/2022] [Indexed: 12/23/2022] Open
Abstract
Introduction Economic evaluation currently focuses almost exclusively on the maximization of health, using the Quality-Adjusted Life-Year (QALY) framework with instruments such as the EQ-5D, with a limited number of health-focused dimensions providing the assessment of health benefit. This evaluative framework is likely to be insufficient for setting priorities in dementia care because of its exclusive concern with health. Data are also often collected from the perspective of a proxy, limiting the voice of those living with dementia in decision-making. This protocol describes a research project that aims to gather the perspectives of people living with dementia, their insights, and preferences for assessing their quality of life to inform economic evaluation outcome measurement and design with a goal of creating a more robust evidence base for the value of healthcare services. Specifically, this study will elucidate what a "good life" means to people living with dementia and how well instruments currently used in economic evaluation meet this description. This project will further test the acceptability of capability wellbeing instruments as self-report instruments and compare them to generic and dementia-specific preference-based instruments. Methods and analysis People living with dementia, diagnosed, or waiting to receive a formal diagnosis and with the capacity to participate in research, will be invited to participate in an hour "think aloud" interview. Participants will be purposefully selected to cover a range of dementia diagnoses, age, and sex, recruited through the integrated care, geriatric, and post-diagnostic clinics at St James' and Tallaght University Hospitals and dementia support groups in the Ireland. During the interview, participants will be invited to reflect on a "good life" and "think aloud" while completing four economic quality of life instruments with a perspective that goes beyond health (AD-5D/QOL-AD, AQOL-4D, ICECAP-O, ICECAP-SCM). An interviewer will then probe areas of difficulty when completing the instruments in a semi-structured way. The analysis will identify the frequency of errors in comprehension, retrieval, judgment, and response from verbatim transcripts. Qualitative data will be analyzed using constant comparison. Ethics The St James's Hospital and Tallaght University Hospital Joint Research Ethics Committee approved the study (Approval Date: 11 April 2022).

Association between antidementia medication use and mortality in people diagnosed with dementia with Lewy bodies in the UK: A retrospective cohort study. PLoS Med 2022; 19:e1004124. [PMID: 36472984 PMCID: PMC9725132 DOI: 10.1371/journal.pmed.1004124] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2022] [Accepted: 10/14/2022] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Dementia with Lewy bodies (DLBs) is a common cause of dementia but has higher mortality than Alzheimer's disease (AD). The reasons for this are unclear, but antidementia drugs (including acetylcholinesterase inhibitors [AChEIs] and memantine) symptomatically benefit people with DLB and might improve outcomes. We investigated whether AChEIs and/or memantine were associated with reduced hospital admissions and mortality. METHODS AND FINDINGS We performed a retrospective cohort study of those diagnosed with DLB between 1 January 2005 and 31 December 2019, using data from electronic clinical records of secondary care mental health services in Cambridgeshire and Peterborough NHS Foundation Trust (CPFT), United Kingdom (catchment area population approximately 0.86 million), as well as linked records from national Hospital Episode Statistics (HES) data. Eligible patients were those who started AChEIs or memantine within 3 months of their diagnosis (cases) and those who never used AChEIs or memantine (controls). Outcomes included admission, length of stay, and mortality. Cox proportional hazard and linear regression models were used. Of 592 patients with DLB, 219 never took AChEIs or memantine, 100 took AChEIs only, and 273 took both AChEIs and memantine. The cohorts were followed up for an average of 896 days, 981 days, and 1,004 days, respectively. There were no significant differences in the cohorts' baseline characteristics, except for socioeconomic status that was lower in patients who never took AChEIs or memantine (χ2 = 23.34, P = 0.003). After controlling for confounding by sociodemographic factors (age, sex, marital status, ethnicity, socioeconomic status), antipsychotic use, antidepressant use, cognitive status, physical comorbidity, anticholinergic burden, and global health performance, compared with patients who never took AChEIs or memantine, patients taking AChEIs only or taking both had a significantly lower risk of death (adjusted hazard ratio (HR) = 0.67, 95% CI = 0.48 to 0.93, p = 0.02; adjusted HR = 0.64, 95% CI = 0.50 to 0.83, P = 0.001, respectively). Those taking AChEIs or both AChEIs and memantine had significantly shorter periods of unplanned hospital admission for physical disorders (adjusted coefficient -13.48, 95% CI = [-26.87, -0.09], P = 0.049; adjusted coefficient -14.21, 95% CI = [-24.58, -3.85], P = 0.007, respectively), but no difference in length of stay for planned admissions for physical disorders, or for admissions for mental health disorders. No significant additional associations of memantine on admission, length of stay, and mortality were found (all P > 0.05). The main limitation was that this was a naturalistic study and possible confounds cannot be fully controlled, and there may be selection bias resulting from nonrandom prescription behaviour in clinical practice. However, we mimicked the intention-to-treat design of clinical trials, and the majority of baseline characters were balanced between cohorts. In addition, our series of sensitivity analyses confirmed the consistency of our results. CONCLUSION In this study, we observed that use of AChEIs with or without memantine in DLB was associated with shorter duration of hospital admissions and decreased risk of mortality. Although our study was naturalistic, it supports further the use of AChEIs in DLB.

Abstract
BACKGROUND Dementia with Lewy bodies (DLB) is one of the most common degenerative dementias. Clinical trials for individuals with DLB are increasing. We aimed to identify commonly used outcome measures for trials in DLB. METHODS A pragmatic literature search of PubMed and clinicaltrials.gov identified interventional studies including populations with DLB. Studies were included if they enrolled participants with DLB and met the National Institutes of Health criteria for a clinical trial. Data were collected using standardized forms. Outcome measures were categorized according to core and supportive features of DLB. RESULTS After de-duplication, 58 trials were identified. The most common cognitive outcome measures were the Mini Mental State Examination (n=24) and Cognitive Drug Research computerized Assessment System (n=5). The Clinician's Assessment of Fluctuations was the most commonly used measure for fluctuations (n=4). Over half of studies used the Neuropsychiatric Inventory to assess behavioral symptoms (n=31). The Unified Parkinson's Disease Rating Scale was frequently used for motor assessment (n=23). CONCLUSIONS AND RELEVANCE Clinical trial outcomes used in DLB are rarely validated in this population and some lack face validity. There is a need to validate existing scales in DLB and develop DLB-specific outcome measures.

Abstract
BACKGROUND Pre-loss grief increases as dementia advances. Caregivers who experience pre-loss grief face risks to their own physical and psychological health. OBJECTIVE The study examined factors associated with pre-loss grief in caregivers of older adults with dementia with Lewy bodies (DLB) to determine whether overall caregiver experiences differ based on the stages of DLB in care recipients. The study also compared pre-loss grief in caregivers of DLB patients with that in caregivers of patients with Alzheimer's disease (AD) and other dementias. METHOD Using a cross-sectional design, 714 caregivers of older adults with dementia (488 DLB, 81 AD, 145 other dementias) completed an online survey on pre-loss grief. Multivariate linear regression identified risk factors associated with pre-loss grief and analysis of variance examined whether pre-loss grief in caregivers differed significantly based on type of dementia or stage of DLB. RESULTS Being the caregiver of a spouse, lower level of caregiver well-being, lower psychological well-being of the caregiver, and higher level of burden were associated (p < 0.005) with increased pre-loss grief in caregivers of older adults with DLB. There was no significant difference in caregiver burden, well-being, or depression according to the various stages of DLB (mild, moderate, severe, deceased) in the care recipients. There was no significant difference in pre-loss grief in caregivers of DLB care recipients compared to caregivers of patients with other dementias. CONCLUSION Assessment of DLB caregivers and appropriate interventions should be conducted to reduce their burden and emotional distress to decrease the incidence of pre-loss grief.

Abstract
Importance Parkinson disease and related disorders (PDRD) have consequences for quality of life (QoL) and are the 14th leading cause of death in the United States. Despite growing interest in palliative care (PC) for persons with PDRD, few studies are available supporting its effectiveness. Objective To determine if outpatient PC is associated with improvements in patient-centered outcomes compared with standard care among patients with PDRD and their caregivers. Design, Setting, and Participants This randomized clinical trial enrolled participants at 3 academic tertiary care centers between November 1, 2015, and September 30, 2017, and followed them up for 1 year. A total of 584 persons with PDRD were referred to the study. Of those, 351 persons were excluded by phone and 23 were excluded during in-person screenings. Patients were eligible to participate if they had PDRD and moderate to high PC needs. Patients were excluded if they had urgent PC needs, another diagnosis meriting PC, were already receiving PC, or were unable or unwilling to follow the study protocol. Enrolled participants were assigned to receive standard care plus outpatient integrated PC or standard care alone. Data were analyzed between November 1, 2018, and December 9, 2019. Interventions Outpatient integrated PC administered by a neurologist, social worker, chaplain, and nurse using PC checklists, with guidance and selective involvement from a palliative medicine specialist. Standard care was provided by a neurologist and a primary care practitioner. Main Outcomes and Measures The primary outcomes were the differences in patient quality of life (QoL; measured by the Quality of Life in Alzheimer Disease scale) and caregiver burden (measured by the Zarit Burden Interview) between the PC intervention and standard care groups at 6 months. Results A total of 210 patients with PDRD (135 men [64.3%]; mean [SD] age, 70.1 [8.2] years) and 175 caregivers (128 women [73.1%]; mean [SD] age, 66.1 [11.1] years) were enrolled in the study; 193 participants (91.9%) were white and non-Hispanic. Compared with participants receiving standard care alone at 6 months, participants receiving the PC intervention had better QoL (mean [SD], 0.66 [5.5] improvement vs 0.84 [4.2] worsening; treatment effect estimate, 1.87; 95% CI, 0.47-3.27; P = .009). No significant difference was observed in caregiver burden (mean [SD], 2.3 [5.0] improvement vs 1.2 [5.6] improvement in the standard care group; treatment effect estimate, -1.62; 95% CI, -3.32 to 0.09; P = .06). Other significant differences favoring the PC intervention included nonmotor symptom burden, motor symptom severity, completion of advance directives, caregiver anxiety, and caregiver burden at 12 months. No outcomes favored standard care alone. Secondary analyses suggested that benefits were greater for persons with higher PC needs. Conclusions and Relevance Outpatient PC is associated with benefits among patients with PDRD compared with standard care alone. This study supports efforts to integrate PC into PDRD care. The lack of diversity and implementation of PC at experienced centers suggests a need for implementation research in other populations and care settings. Trial Registration ClinicalTrials.gov Identifier: NCT02533921.

Abstract
Background: Quality of Life (QoL) is an important outcome measure in dementia, particularly in the context of interventions. Research investigating longitudinal QoL in dementia with Lewy bodies (DLB) is currently lacking. Objective: To investigate determinants and trajectories of QoL in DLB compared to Alzheimer’s disease (AD) and controls. Methods: QoL was assessed annually in 138 individuals, using the EQ5D-utility-score (0–100) and the health-related Visual Analogue Scale (VAS, 0–100). Twenty-nine DLB patients (age 69±6), 68 AD patients (age 70±6), and 41 controls (age 70±5) were selected from the Dutch Parelsnoer Institute-Neurodegenerative diseases and Amsterdam Dementia Cohort. We examined clinical work-up over time as determinants of QoL, including cognitive tests, neuropsychiatric inventory, Geriatric Depression Scale (GDS), and disability assessment of dementia (DAD). Results: Mixed models showed lower baseline VAS-scores in DLB compared to AD and controls (AD: β±SE = -7.6±2.8, controls: β±SE = -7.9±3.0, p < 0.05). An interaction between diagnosis and time since diagnosis indicated steeper decline on VAS-scores for AD patients compared to DLB patients (β±SE = 2.9±1.5, p < 0.1). EQ5D-utility-scores over time did not differ between groups. Higher GDS and lower DAD-scores were independently associated with lower QoL in dementia patients (GDS: VAS β±SE = -1.8±0.3, EQ5D-utility β±SE = -3.7±0.4; DAD: VAS = 0.1±0.0, EQ5D-utility β±SE = 0.1±0.1, p < 0.05). No associations between cognitive tests and QoL remained in the multivariate model. Conclusion: QoL is lower in DLB, while in AD QoL shows steeper decline as the disease advances. Our results indicate that non-cognitive symptoms, more than cognitive symptoms, are highly relevant as they impact QoL.

Abstract
Dementia with Lewy bodies and Parkinson's disease dementia, jointly known as Lewy body dementia, are common neurodegenerative conditions. Patients with Lewy body dementia present with a wide range of cognitive, neuropsychiatric, sleep, motor, and autonomic symptoms. Presentation varies between patients and can vary over time within an individual. Treatments can address one symptom but worsen another, which makes disease management difficult. Symptoms are often managed in isolation and by different specialists, which makes high-quality care difficult to accomplish. Clinical trials and meta-analyses now provide an evidence base for the treatment of cognitive, neuropsychiatric, and motor symptoms in patients with Lewy body dementia. Furthermore, consensus opinion from experts supports the application of treatments for related conditions, such as Parkinson's disease, for the management of common symptoms (eg, autonomic dysfunction) in patients with Lewy body dementia. However, evidence gaps remain and future clinical trials need to focus on the treatment of symptoms specific to patients with Lewy body dementia.

Abstract
BACKGROUND Advanced Parkinson's disease (PD) is a multidimensional neurodegenerative condition with motor and non-motor symptoms contributing to increasing disability and decreasing quality of life. As the disease progresses, patients may become homebound and estranged from neurological care, with dire consequences. We describe the increasing epidemiologic burden of and individual risks faced by patients with palliative-stage PD and their caregivers. METHODS With the aim of mitigating these risks, we designed and iterated two models of interdisciplinary home visits to maintain continuity of care and illuminate the unmet needs and barriers to care faced by this population. We describe both models in detail, with data on feasibility and patient-centered outcomes achieved in the initial model, and baseline characteristics of participants in the ongoing expanded model. Finally, we illustrate the scope and common themes of such palliative care-informed home visits with two cases. RESULTS The pilot model involved over 380 visits with 109 individual patients. Among those patients, PD severity worsened by nearly 12 points annually on the Unified Parkinson's Disease Rating Scale (UPDRS), without a corresponding decline in quality of life. In an ongoing study of the second iteration of the model, 52 patient-caregiver dyads have completed their initial visit, with 44% bearing a diagnosis of dementia and the majority requiring an assistive device or being bedbound. Two cases highlight the critical importance of thorough medication reconciliation and home safety assessment in the comprehensive evaluation and management of such patients. CONCLUSIONS As our population ages, therapies increase, and the number of individuals living with advanced PD and related disorders grows, so too does the imperative to recognize and address the palliative care needs of such patients and families. For many, home may be a viable, and perhaps optimal, site for this care.

Abstract
BACKGROUND The Quality of Life in Alzheimer's Disease Scale (QOL-AD) developed by Logsdon et al. in1999 is believed to be useful for evaluating responses from both patients and their caregivers. We previously confirmed both the reliability and the validity of the Japanese version of the QOL-AD. However, the factor structure of this scale should be confirmed because the QOL-AD covers multiple facets of dementia patients' lives. Thus, we performed a factor analysis of the Japanese QOL-AD. Then, we examined the correlations between each of the identified QOL factor scores and the results of other scales. METHODS The Japanese version of the QOL-AD was given to 132 AD patients and 132 caregivers. Four other tests were also performed at the same time: the Mini-Mental State Examination, the Neuropsychiatric Inventory (NPI), the Hyogo Activities of Daily Living Scale (HADL), and the Short Memory Questionnaire. A factor analysis using Varimax rotation was used to examine the dimensions underlying the QOL-AD. In addition, we examined the Pearson correlations between each of the identified QOL factor scores and the results of the other four tests. RESULTS Factor analyses of both versions of the Japanese QOL-AD (both the patients' and the caregivers' responses) revealed three factors that were named 'psychological wellbeing', 'human relationships', and 'physical and social environment'. The 'psychological wellbeing' factor was significantly correlated with the Mood factor of the NPI. The 'human relationships' factor was significantly correlated with the Psychosis factor of the NPI. The 'physical and social environment' factor was significantly correlated with the HADL. CONCLUSIONS Both the patients' and the caregivers' responses to the Japanese version of the QOL-AD were composed of three factors: 'psychological wellbeing', 'human relationships', and 'physical and social environment'. The present results support the multi-domain concept of QOL proposed by Lawton.

Abstract
INTRODUCTION A significant proportion of dementia is concretely estimated to be attributable to dementia with Lewy bodies (DLB)-one of the most common types of progressive dementia; however, there is a paucity of literature on this disease. We aimed to examine available evidence to gain a better understanding of its treatment landscape, clinical management, and disease burden. METHODS A systematic literature review captured any DLB studies that report on randomised controlled trials (RCTs), epidemiology, disease progression, and economic data. An additional targeted literature review captured studies reporting on clinical management and quality of life (QoL) in this disease. Publication date was limited to 1 January 2007-26 March 2018, with the exception for RCTs, where no time restrictions were applied. FINDINGS Of the 3486 studies initially identified, 55 studies were eligible for inclusion. The studies were mainly from Europe (n = 29), the USA (n = 9), and Japan (n = 8). Mini-Mental State Examination and Neuropsychiatric Inventory scores were the most commonly reported clinical outcomes in RCTs (n = 14). The most frequently identified interventions reported in RCTs were donepezil and memantine. Patients with DLB typically reported worse outcomes in relation to efficacy and safety, cognitive impairment, survival, and QoL compared with those with Alzheimer's disease (AD). Additionally, patients with DLB were associated with higher hospitalisation rates and cost of care. Furthermore, there is a reliance on a small number of consensus guidelines. Of these, only one set of guidelines (DLB Consortium) was developed specifically for DLB. CONCLUSION The paucity of data indicates an unmet need in this therapy area. Although several studies look into the clinical and pathological aspects of DLB, consensus guidelines and studies on healthcare utilisation in patients with dementia have largely focused on AD. Additionally, most of the findings were made in comparison with AD. FUNDING Eisai Inc.

Abstract
INTRODUCTION Quality of life (QOL) assessments allow for more complete evaluation of patients' lived experiences in relation to chronic conditions, such as Parkinson's disease (PD). In palliative care, such instruments are vital to ensure QOL issues are catalogued and addressed for patients. However, little is known regarding the psychometric properties of quality of life scales for use in palliative care for PD, specifically. METHODS 210 participants with parkinsonian disorders, who participated in a larger palliative intervention clinical trial, completed four quality of life scales (PDQ-39, PROMIS-29, QOL-AD, and McGill QOL) at baseline and post-intervention. Psychometric properties, including internal consistency and concurrent validity, were examined. Factor analyses were performed to evaluate relationships between scale items. Minimal clinically important differences (MCID) and responsiveness were calculated for each scale. RESULTS All scales demonstrated good internal consistency and concurrent validity. Factor analyses revealed few deviations from the defined subdomains of the scales. Mean absolute MCID values were estimated at 12.7, 10.9, 3.9, and 18.9 for PDQ-39, PROMIS-29, QOL-AD, and McGill QOL, respectively. The PDQ-39 and PROMIS-29 demonstrated higher responsiveness to palliative intervention, while the QOL-AD was more responsive in the control group. CONCLUSIONS The PDQ-39, PROMIS-29, QOL-AD, and McGill QOL are all valid for use in PD palliative care, though subdomains of the scales in this population may differ slightly from those initially defined. We recommend the use of PDQ-39 and PROMIS-29 as outcome measures in clinical trials for palliative care in PD, though the QOL-AD may be superior for tracking disease progression.

Abstract
INTRODUCTION Dementia with Lewy bodies (DLB) is the second most common type of dementia in people over 65 years of age. Given the complex clinical phenotype, the management of DLB may be challenging, especially considering that there is limited evidence about specific interventions, and there are currently no Food and Drug Administration (FDA)/European Medicines Agency (EMA)-approved medications. AREAS COVERED This article provides an overview of the current pharmacotherapy in DLB and gives review to the most recent drug candidates in clinical trials. EXPERT OPINION Commonly prescribed drugs are primarily aimed at treating the most troublesome clinical features of DLB. Although these medications provide some benefit to symptoms, there is, unfortunately, a lack of DLB-specific evidence on effective treatments and their off-label use. Indeed, most treatments used come from clinical trials on patients with Alzheimer's disease or Parkinson's disease. Thus, there is an urgent need for randomized clinical trials in DLB patients. Despite several challenges, potential new drugs are in ongoing clinical trials; furthermore, as our understanding of molecular and cellular mechanisms underlying DLB broaden, it is likely that we will identify novel drug targets for the development of better and more effective symptomatic products and disease-modifying therapies.

Abstract
Dementia with Lewy bodies (DLB) is a complex, multisymptom disorder. When making decisions regarding the treatment of DLB, the patient's quality of life (QoL) should always be the main consideration. To our knowledge, this is the first review article focusing on the QoL in DLB patients. We searched the PubMed database using the keywords "quality of life" and "dementia with Lewy bodies." Previously, no specific instrument had been developed for assessing the QoL in DLB patients. Patients with DLB have a decreased QoL compared to patients with Alzheimer's disease, which is reportedly caused by several factors including level of independence in instrumental activities of daily living, whether the patient is living with the caregiver, apathy, delusion, and dysautonomia. The direct effect of visual hallucination, sleep, and movement disorders on the QoL in DLB patients has not been previously studied. The role of cognitive function on the QoL is still controversial. In a randomized controlled study, memantine may improve the QoL in PDD or DLB patients. We concluded that it is important to develop a specific instrument to assess the QoL in DLB patients. Furthermore, there is an urgent need for large clinical trials to identify factors associated with the QoL and how they can be managed.

Abstract
Among patients with Parkinson's disease (PD), depression is prevalent and disabling, impacting both health outcomes and quality of life. There is a critical need for alternative pharmacological methods to treat PD depression, as mainstream antidepressant drugs are largely ineffective in this population. Currently, there are no recommendations for the optimal treatment of PD neuropsychiatric symptoms. Given the dual antidepressant and anti-dyskinetic effects of ketamine and other N-methyl-D-aspartate (NMDA) antagonists for PD, this review aims to examine the current evidence of NMDA antagonists for treating neuropsychiatric symptoms, including memantine, amantadine, ketamine, dizoclopine, and d-cycloserine. A comprehensive literature search was conducted using the PubMed database. We also searched the following databases up to March 1, 2018: Ovid MEDLINE, PsycINFO, CINAHL, Google Scholar, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews. The following keywords were used: NMDA antagonist and Parkinson's disease. Two authors independently reviewed the articles identified from the search using specific selection criteria, focusing on studies of mood, psychiatric condition, depression, cognition, and quality of life, and the consensus was reached on the 20 studies included. There is a preliminary evidence that NMDA antagonists may modulate psychiatric symptoms in PD. However, current evidence of psychiatric symptom-modifying effects is inconclusive and requires that further trials be conducted in PD. The repurposing of old NMDA antagonists, such as ketamine for depression and newer therapies, such as rapastinel, suggests that there is an emerging place for modulating the glutamatergic system for treating non-motor symptoms in PD.

Abstract
This article describes the practical considerations in the clinical medical treatment in dementia with Lewy body (DLB) patients. It is illustrated with the voice of a DLB sufferer and his wife. According to our experience, emanating from a 15 year collaboration between a doctor and a nurse at a memory clinic, there are several possible therapeutical entrances. However, the order in which the medication is introduced is of great importance to avoid aggravation of other DLB symptoms. We start the treatment with cholinesterase inhibitor and memantine, and; thereafter, we treat the most disturbing symptom. Thereafter, we consider if orthostatic hypotension is present and treat it. In the treatment of depression and anxiety it is beneficial to use agents affecting both noradrenalin and serotonin. Dysphagia may be lethal but can be improved with carbohydrate drinks. These and other aspects are commented upon from our experience and are also reflected in relation to studies evaluating the existing level of evidence.

Abstract
Parkinson's disease (PD) is a progressive neurodegenerative disease primarily characterized by the hallmarks of motor symptoms, such as tremor, bradykinesia, rigidity, and postural instability. However, through clinical investigations in patients and experimental findings in animal models of Parkinson's disease for years, it is now well recognized that Parkinson's disease is more than just a motor-deficit disorder. The majority of Parkinson's disease patients suffer from nonmotor disabilities, for instance, cognitive impairment, autonomic dysfunction, sensory dysfunction, and sleep disorder. So far, anti-PD prescriptions and surgical treatments have been mainly focusing on motor dysfunctions, leaving cognitive impairment a marginal clinical field. Within the nonmotor symptoms, cognitive impairment is one of the most common and significant aspects of Parkinson's disease, and cognitive deficits such as dysexecutive syndrome and visuospatial disturbances could seriously affect the quality of life, reduce life expectancy, prolong the duration of hospitalization, and therefore increase burdens of caregiver and medical costs. In this review, we have done a retrospective study of the recent related researches on epidemiology, clinical manifestation and diagnosis, genetics, and potential treatment of cognitive deficits in Parkinson's disease, aiming to provide a summary of cognitive impairment in Parkinson's disease and make it easy for clinicians to tackle this challenging issue in their future practice.

Abstract
Cognitive and neuropsychiatric symptoms are common in Parkinson's Disease and may surpass motor symptoms as the major factors impacting patient quality of life. The symptoms may be broadly separated into those associated with the disease process and those that represent adverse effects of treatment. Symptoms attributed to the disease arise from pathologic changes within multiple brain regions and are not restricted to dysfunction in the dopaminergic system. Mood symptoms such as depression, anxiety, and apathy are common and may precede the development of motor symptoms by years, while other neuropsychiatric symptoms such as cognitive impairment, dementia, and psychosis are more common in later stages of the disease. Neuropsychiatric symptoms attributed to treatment include impulse control disorders, pathologic use of dopaminergic medications, and psychosis. This manuscript will review the current understanding of neuropsychiatric symptoms in Parkinson's Disease.

Abstract
Background There is a lack of standardisation in quality of life (QoL) measurements to be used in older multimorbid patients. An ideal QoL measurement should be reliable, valid, subjective, multidimensional, feasible and generic. We hypothesised that the QoL-AD (Quality of Life in Alzheimer’s Disease) scale could have these properties. Our aim was to determine the psychometric properties and clinical correlations of QoL-AD in a population of elderly, multimorbid medical inpatients. Methods QoL-AD was performed in 200 medical inpatients, and available caregivers. Reliability was determined using cronbach’s alpha and corrected item-total correlations. The agreement between patient and proxy ratings were examined using intra-class correlations (ICC). Correlations between QoL-AD and demographic data, comorbidity, cognitive tests, ADL (activities of daily living) and depression were examined. To characterise the underlying constructs of QoL-AD, an exploratory factor analysis was performed. Results In total, 199 patients fulfilled the QoL-AD rating, with 139 proxy ratings. Cronbach’s alpha (95 % CI) was 0.74 (0.68–0.79) for patients and 0.86 (0.83–0.90) for proxies. Patient-proxy ICC (95 % CI) was 0.31 (0.16–0.46). Lower QoL was correlated to depression, cognitive impairment, ADL impairment and solitary living, but not with comorbidity. The factor analysis gave a three-factor solution, with factors representing phsyical, social and psychological well-being. Conclusion The QoL-AD scale showed some promising properties but more research is needed before it can be recommended in this setting. If replicated, the finding that cognitive impairment, depression and ADL impairment were more associated with lower QoL than somatic comorbidity could have clinical implications for further studies aiming to improve QoL in this population.

Abstract
Background The aim of this work was to utilize meta-analysis in examining the effects of memantine on neuropsychological functioning in patients with Parkinson's disease dementia (PDD) and dementia with Lewy bodies (DLB). Methods Included studies fulfilled these criteria: included objective cognitive measures, a comparison group of participants not taking memantine, and provided sufficient data for calculation of effect size. We examined effect sizes across global cognition and five specific neuropsychological domains. Moderator variables examined included neuropsychological domain, diagnostic cohort (PDD, DLB, or mixed PDD-DLB cohort), study design (open label or placebo-controlled), and trial length. Results Six publications met inclusion criteria totaling 57 effects. Homogeneity analysis across cognitive domains revealed a small overall effect size (d = 0.25) that was significantly heterogeneous (P < 0.001). Specific neuropsychological domains did not moderate effect size, though. Moderator analysis studies using a mix of DLB and PDD subjects showed larger effects than those that included DLB or PDD patients only. Additionally, open-label trials had significantly (P < 0.001) larger effect sizes (d = 1.32) than placebo-controlled trials (d = 0.12). Conclusions The present study indicates that effect-size heterogeneity across studies of memantine in DLB and PDD patients is moderated by diagnostic makeup of the cohort and study design. The small overall effect size noted in placebo-controlled trials versus open-label trials indicates that memantine has minimal effects on cognition in PDD and DLB and is unlikely to demonstrate clinically significant improvements in cognition.

Abstract
BACKGROUND Parkinson's disease dementia (PDD) is a major cause of morbidity and mortality in Parkinson's disease (PD), which severely affects patient functioning and quality of life and increases the risk for nursing home admission. Unfortunately, current treatment options for PDD are limited and have only marginal therapeutic effects. As novel treatments are developed, there will be a need to assess their efficacy in well-designed randomized controlled trials. However, there is no consensus on the optimal outcome measures for use in PDD clinical trials. METHODS A systematic review of PDD clinical trials and empiric studies of outcome measures used in PDD was performed. Outcome measures were divided into five categories: 1) cognitive; 2) behavioral and mood; 3) activities of daily living and quality of life; 4) global; and 5) caregiver burden. FINDINGS A total of 20 PDD pharmacologic clinical trials were identified. These trials incorporated a broad array of outcome measures, which were used inconsistently across trials. We summarize the psychometric properties and other relevant data on outcome measures used, including their diagnostic utility, inter-rater reliability, test-retest reliability, responsiveness, clinically meaningful change, and availability of alternate forms. CONCLUSIONS We have identified the best-evidenced PDD outcome measures in each domain. Further research is needed to assess the validity, reliability, and clinically meaningful change of these measures in PDD to inform the design of future clinical trials and enhance the ability of clinicians, researchers and policy-makers to interpret study results. In addition, the development of outcome measures specific to PDD may be warranted.

Abstract
OBJECTIVE Memantine, an uncompetitive antagonist of N-methyl-d-aspartate receptors, may have a role in managing symptoms associated with dementia in Parkinson's disease (PDD), although its role in improving patient-reported outcomes (PROs) has not been extensively investigated. PROs may be more sensitive than standard psychometric measures for detecting change in complex conditions such as PDD. The aim of this study was to examine the effect of memantine on PROs: individually determined goals and health-related quality of life. We also examined memantine's effect on caregiver burden. METHODS This 22-week double-blind randomised controlled trial evaluated participants with PDD on 20 mg of memantine or placebo. Outcome measures were Goal Attainment Scaling (GAS), the Parkinson's Disease Questionnaire-8 and the Zarit Burden Inventory. RESULTS A significantly greater proportion of participants on memantine (64%) had better than expected GAS outcomes compared with those on placebo (7%) (p = 0.007). Furthermore, the improvement in mean GAS score, as well as mean caregiver burden score, from baseline to drug discontinuation was significantly greater in those on memantine compared with those on placebo (p = 0.03 and 0.04, respectively). Significant differences in quality of life were not seen. CONCLUSIONS In this study, memantine improved individually set goals and caregiver burden in PDD. This suggests that clinimetric measures such as GAS may be more sensitive than conventional psychometric measures in detecting improvements in people with PDD.

Abstract
OBJECTIVE To investigate the effect on survival of treatment with memantine in patients with dementia with Lewy bodies (DLB) and Parkinson's disease with dementia (PDD). METHODS 75 patients with DLB and PDD were included in a prospective double-blinded randomised placebo-controlled trial (RCT) of memantine, of whom long-term follow-up was available for 42. Treatment response was recorded 24 weeks from baseline and measured by Clinical Global Impression of Change (CGIC). The participants were grouped as responders (CGIC 1-3) or non-responders (CGIC 4-7). The 24-week RCT was followed by open-label treatment and survival was recorded at 36 months. RESULTS After 36-month follow-up, patients in the memantine group had a longer length of survival compared with patients in the placebo group (log rank x²=4.02, p=0.045). Within the active treatment group, survival analysis 36 months from baseline showed that the memantine responders, based on CGIC, had higher rates of survival compared with the non-responders (log rank x²=6.595, p=0.010). Similar results were not seen in the placebo group. CONCLUSIONS Early treatment with memantine and a positive clinical response to memantine predicted longer survival in patients with DLB and PDD. This suggests a possible disease-modifying effect and also has implications for health economic analysis. However, owing to the small study sample, our results should merely be considered as generating a hypothesis which needs to be evaluated in larger studies. TRIAL REGISTRATION NUMBER ISRCTN89624516.

Abstract
Dementia is one of the most common and important aspects of Parkinson's disease and has consequences for patients and caregivers, and has health-related costs. Mild cognitive impairment is also common and frequently progresses to dementia. The underlying mechanisms of dementia associated with Parkinson's disease are only partly known and no mechanism-based treatments are available. Both dysmetabolism of α-synuclein and amyloid-protein and cholinergic deficits contribute to cognitive impairment in Parkinson's disease, and preliminary findings show that imaging and neurophysiological and peripheral biomarkers could be useful in diagnosis and prognosis. Rivastigmine is the only licensed treatment for dementia in Parkinson's disease, but emerging evidence suggests that memantine might also be useful. Whether these or other treatments can delay the progression from mild cognitive impairment to dementia in Parkinson's disease is a key research question.

Abstract
Background N-methyl-D-aspartic acid antagonists (memantine) and cholinesterase inhibitors (ChEIs) are the only two approved classes of drugs to treat dementia; this paper explores the evidence for using these two treatments in combination. Objective To determine the efficacy and safety of using combination therapy with memantine and a ChEI to treat dementia in comparison to monotherapy with either memantine or a ChEI. Methods In March 2012, we systematically searched MEDLINE/PubMed, EMBASE, Cochrane library, and grey literature databases. All study types were included, except for case series or reports, which looked at combination therapy versus monotherapy in various dementing disorders. Data was pooled for blinded randomized controlled trials (RCTs) only; mean differences and standardized mean differences were used to determine effect sizes. Results Thirteen studies were included in this review; 3 were blinded RCTs, with a total of 971 Alzheimer's disease (AD) patients, which were included into the meta-analysis. No papers were found that primarily addressed combination therapy in other dementias. In the meta-analysis, small but statistically significant effect sizes were seen in favor of combination therapy among patients with moderate to severe AD on the scales of cognition (0.45–0.52; p < 0.0001), scales of functional outcomes (0.23–0.3; p < 0.01), and the neuropsychiatric inventory (3.7–4.4; p < 0.0001). Among the open-label studies, 3 out of 6 suggested benefits, as did the 4 included cohort studies. However, the high risk of bias encountered in the latter two study designs limits deducing any conclusions about benefit. Conclusion Although there were statistically significant changes in favor of combination therapy in moderate to severe AD, heterogeneity in scales and patient characteristics exists. However, it is unclear if clinically significant outcomes can be achieved using the combination therapy. More studies are required before a recommendation for combination therapy can be made.

Abstract
Elderly patients are at increased risk of drug-related morbidity and mortality. Avoiding the use of potentially inappropriate medications (PIMs) is one of the strategies that has been widely adopted to reduce the harmful consequences of drug use. There are several PIM screening tools available. In this review, we provide an overview of existing screening tools to detect PIMs in the elderly, emphasizing the advantages and disadvantages of each. Combining previously published and adopted tools (adjusted Beers list, French consensus panel, McLeod's list, and Lindblad's list of clinically important drug-disease interactions), we develop a new comprehensive tool that also includes the adjusted Hanlon's and Malone's lists of potentially serious drug-drug interactions in the elderly. In addition to listed PIMs and clinically important drug-drug interactions, alternative therapeutic solutions are suggested. The new protocol differentiates: drugs with an unfavorable benefit/risk ratio (to be avoided regardless of the underlying disease/condition), drugs with a questionable efficacy, and drugs to be avoided with certain diseases/conditions, and provides a list of potentially serious drug-drug interactions. A tool consisting of PIMs and potential drug-drug interactions within the same protocol provides more comprehensive quality assessment of drug-prescribing behavior to the elderly, which in turn may lead to better prescribing practices.
