Wang Y, Monai H. Transcranial direct current stimulation alters cerebrospinal fluid-interstitial fluid exchange in mouse brain. Brain Stimul 2024; 17:620-632. [PMID: 38688399 DOI: 10.1016/j.brs.2024.04.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 03/28/2024] [Accepted: 04/15/2024] [Indexed: 05/02/2024] Open
Abstract
BACKGROUND Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that has gained prominence recently. Clinical studies have explored tDCS as an adjunct to neurologic disease rehabilitation, with evidence suggesting its potential in modulating brain clearance mechanisms. The glymphatic system, a proposed brain waste clearance system, posits that cerebrospinal fluid-interstitial fluid (CSF-ISF) exchange aids in efficient metabolic waste removal. While some studies have linked tDCS to astrocytic inositol trisphosphate (IP3)/Ca2+ signaling, the impact of tDCS on CSF-ISF exchange dynamics remains unclear. HYPOTHESIS tDCS influences the dynamics of CSF-ISF exchange through astrocytic IP3/Ca2+ signaling. METHODS In this study, we administered tDCS (0.1 mA for 10 min) to C57BL/6N mice anesthetized with ketamine-xylazine (KX). The anode was positioned on the cranial bone above the cortex, and the cathode was inserted into the neck. Following tDCS, we directly assessed brain fluid dynamics by injecting biotinylated dextran amine (BDA) as a CSF tracer into the cisterna magna (CM). The brain was then extracted after either 30 or 60 min and fixed. After 24 h, the sectioned brain slices were stained with Alexa 594-conjugated streptavidin (SA) to visualize BDA using immunohistochemistry. We conducted Electroencephalography (EEG) recordings and aquaporin 4 (AQP4)/CD31 immunostaining to investigate the underlying mechanisms of tDCS. Additionally, we monitored the efflux of Evans blue, injected into the cisterna magna, using cervical lymph node imaging. Some experiments were subsequently repeated with inositol trisphosphate receptor type 2 (IP3R2) knockout (KO) mice. RESULTS Post-tDCS, we observed an increased CSF tracer influx, indicating a modulation of CSF-ISF exchange by tDCS. Additionally, tDCS appeared to enhance the brain's metabolic waste efflux. EEG recordings showed an increase in delta wave post-tDCS. But no significant change in AQP4 expression was detected 30 min post-tDCS. Besides, we found no alteration in CSF-ISF exchange and delta wave activity in IP3R2 KO mice after tDCS. CONCLUSION Our findings suggest that tDCS augments the glymphatic system's influx and efflux. Through astrocytic IP3/Ca2+ signaling, tDCS was found to modify the delta wave, which correlates positively with brain clearance. This study underscores the potential of tDCS in modulating brain metabolic waste clearance.

Abstract
BACKGROUND Audit and Feedback (A&F), a strategy aimed at promoting modified practice through performance feedback, is a method to change provider behaviour and reduce unnecessary medical services. This study aims to assess the use of A&F to reduce antibiotic prescribing for viral infections and antipsychotic prescribing to patients with dementia. METHODS Clustered randomized trial of 239 primary care providers in Manitoba, Canada, participating in the Manitoba Primary Care Research Network. Forty-six practices were randomly assigned to one of three groups: control group, intervention 1 (recommendations summary), intervention 2 (recommendations summary and personalized feedback). We assessed prescribing rates prior to the intervention (2014/15), during and immediately after the intervention (2016/17) and following the intervention (2018/19). Physician characteristics were assessed. RESULTS Between 2014/15-2016/17, 91.6% of providers in intervention group 1 and 95.9% of providers in intervention group 2 reduced their antibiotic and antipsychotic prescribing rate by ≥ 1 compared to the control group (77.6%) (p-value 0.0073). This reduction was maintained into 2018/19 at 91.4%. On multivariate regression alternatively funded providers had 2.4 × higher odds of reducing their antibiotic prescribing rate compared to fee-for-service providers. In quantile regression of providers with a reduction in antibiotic prescribing, alternatively funded (e.g. salaried or locum) providers compared to fee-for-service providers were significant at the 80th quantile. CONCLUSIONS Both A&F and recommendation summaries sent to providers by a trusted source reduced unnecessary prescriptions. Our findings support further scale up of efforts to engage with primary care practices to improve care with A&F. TRIAL REGISTRATION ClinicalTrials.gov NCT05385445, retrospectively registered, 23/05/2022.

Abstract
The inhibition of acetylcholinesterase plays a vital role in the treatment of Alzheimer disease. This study aimed to explore the acetylcholinesterase inhibition potential of Phyllanthus amarus and its phytoconstituents through an in vitro and in silico approach. The in vitro acetylcholinesterase inhibitory activity of P amarus was carried out, followed by the molecular docking studies of its phytoconstituents. The top-ranked molecules identified through molecular docking were subjected to molecular dynamics simulation (MDS) and density functional theory (DFT) studies. The results obtained revealed the methanolic extract of P amarus as a potent acetylcholinesterase inhibitor, while amarosterol A, hinokinin, β-sitosterol, stigmasterol and ellagic acid were identified as potential acetylcholinesterase inhibitors. The MDS and DFT results are in agreement with those obtained from the docking studies. Our findings suggest further studies on the hit molecules.

How Singing can Help People With Dementia and Their Family Care-Partners: A Mixed Studies Systematic Review With Narrative Synthesis, Thematic Synthesis, and Meta-Integration. Front Psychol 2021; 12:764372. [PMID: 34707550 PMCID: PMC8542693 DOI: 10.3389/fpsyg.2021.764372] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Accepted: 09/10/2021] [Indexed: 11/23/2022] Open
Abstract
Background: Recent research on the efficacy of music-based interventions for people with dementia have focused on specific outcomes and methods, and singing has been noted as a particularly beneficial activity. However, due to heterogeneity of research methods, there is a need to synthesise the findings of both quantitative and qualitative research in order to better understand both the impact and potential mechanisms of singing for people in this population. Method: This systematic review included quantitative, qualitative and mixed-methods studies, and analysed these using a systematic mixed-studies synthesis (with a results-based convergent approach). Quantitative and qualitative data were initially synthesised using a narrative synthesis and thematic synthesis method, respectively, before a final meta-integration method was used to synthesise common themes across the two data forms. Results: Electronic and hand search strategies revealed 1,815 relevant studies, 40 of which met the full eligibility criteria. Narrative synthesis of quantitative data revealed six key outcome areas (quality of life; psychological well-being; cognition; engagement; activities of daily living; care-partner well-being), and thematic synthesis of qualitative data generated seven themes relating to the impact and mechanisms of singing (pragmatic elements; social benefits; mood; identity; memory; flow-on effects; and relationships). Meta-integration identified four key areas relating to the impact and mechanisms of singing for people with dementia and care-partners: psychological well-being, quality of life, cognition, and care-partner well-being. Conclusion: Results from the syntheses suggest that singing can positively impact the lives of people with dementia and their care-partners, although due to heterogeneity of study design and outcome measures, it is difficult to draw conclusions based on quantitative data alone. Qualitative data provides further context and insights from participant perspectives, and when integrated with quantitative data, contextual factors that may influence the benefits that participants experience from singing are revealed.

Pharmaceutics 2021; 13:pharmaceutics13091523. [PMID: 34575599 PMCID: PMC8469994 DOI: 10.3390/pharmaceutics13091523] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2021] [Revised: 09/02/2021] [Accepted: 09/10/2021] [Indexed: 11/16/2022] Open
Abstract
Quetiapine is an atypical antipsychotic approved for treating schizophrenia, bipolar depression, and mania but is frequently used in an off-label manner to control the behavioral and psychological symptoms of dementia in elderly patients with dementia. Due to the need to personalize doses for elderly patients with dementia, quetiapine tablet manipulation is widespread in hospital settings, long-term care facilities, and patient homes. The aim of this study was to assess the impact of the different splitting techniques on quetiapine fumarate tablets by analysing the obtained sub-divided tablets and to discuss compliance with the European Pharmacopoeia limits on whole and split tablets. Quetiapine fumarate tablets of two dose strengths were taken at random (in a number able to assure a power of 0.8 during statistical comparison) and were split with a kitchen knife or tablet cutter. The weight and the drug content were determined for each half tablet. The obtained data were compared to the European Pharmacopoeia limits. The differences between the different splitting techniques were statistically tested. Data showed that split tablets, independently of the dose strength and the technique employed, were not compliant with the European Pharmacopoeia specifications for both entire and subdivided tablets in terms of weight and content uniformity. Thus, such a common practice could have potential effects on treatment efficacy and toxicity, especially when also considering the fragility of the elderly target population in which polypharmacotherapy is very common. These results indicate a compelling need for flexible quetiapine formulations that can assure more accurate dose personalization.

Abstract
With the advancement of Alzheimer's disease as well as other types of dementia, in addition to the cognitive decline, psychiatric symptoms have been outlined, including psychotic symptoms. The aim of the study is to review the available results on the antipsychotic treatment of Alzheimer's disease associated psychotic symptoms. The main objective of the study is to evaluate the efficacy of the treatment. The second objective is to assess the tolerability of this treatment. Double-blind, randomized, placebo-controlled trials, which took place over the course of at least 4 weeks, have been searched. Studies that compared one atypical antipsychotic to placebo, as well as more atypical antipsychotics, compared one to another, have been taken into account. In total 17 studies have been selected. The efficacy of the atypical antipsychotics has proven to be significant in most studies. Moreover, antipsychotic medication, such as risperidone, aripiprazole, olanzapine, quetiapine and pimavanserin, has been well tolerated. Atypical antipsychotics are the treatment of choice for psychotic symptoms in dementia. Despite the consistent results present in the literature up to this point, various antipsychotics remain insufficiently studied and would need more generous sample sizes for their outcomes to be substantiated.

Abstract
Older adults experience hallucinations in a variety of social, physical, and mental health contexts. Not everyone is open about these experiences, as hallucinations are surrounded with stigma. Hence, hallucinatory experiences in older individuals are often under-recognized. They are also commonly misunderstood by service providers, suggesting that there is significant scope for improvement in the training and practice of professionals working with this age group. The aim of the present article is to increase knowledge about hallucinations in older adults and provide a practical resource for the health and aged-care workforce. Specifically, we provide a concise narrative review and critique of (1) workforce competency and training issues, (2) assessment tools, and (3) current treatments and management guidelines. We conclude with a brief summary including suggestions for service and training providers and future research.

Abstract
BACKGROUND Choosing Wisely Canada is an initiative to reduce overprescribing and overtesting. This study assessed adherence to 4 Choosing Wisely Canada recommendations for interventions commonly performed in primary care: (a) antibiotic prescriptions for infections that are probably viral in origin, (b) routine vitamin D tests in low-risk adults, (c) annual screening blood tests and (d) prescriptions of antipsychotic medication to treat symptoms of dementia. METHODS We conducted a retrospective cohort study of data from the electronic medical records of patients who had an encounter between 2014 and 2016 with a participating Manitoba Primary Care Research Network primary care provider in Manitoba, Canada. Patient encounter data were reviewed for prescribing and testing practices. Descriptive statistics and multivariable models assessed associations between patient and provider characteristics and rates of prescribing and testing. RESULTS Data for 164 195 patients from 230 providers were included in the study. Sixteen percent (n = 25 629) of patients had an encounter that involved potentially unnecessary diagnostic testing and treatment. A minority of providers contributed to above-average rates of prescribing and testing: 29% (n = 69) of providers prescribed antibiotics for a viral indication,11% (n = 24) prescribed an antipsychotic to a patient diagnosed with dementia, 9% (n = 24) ordered prostate-specific antigen tests and 14% (n = 34) ordered vitamin D tests at above-average rates, respectively. Patient and provider characteristics were associated with each of the prescribing and testing practices assessed. INTERPRETATION This study demonstrated that fewer than 30% of primary care providers contributed to interventions in direct contradiction to Choosing Wisely Canada recommendations. Improvement strategies specific to each prescription or testing recommendation should target specific providers to prevent patient harm and reduce unnecessary health care spending.

Abstract
RATIONALE Age-related macular degeneration (AMD) is one of the leading causes of blindness among the elderly. Due to its complex etiology, current treatments have been insufficient. Previous studies reveal three systems closely involved in AMD pathogenesis: lipid metabolism, oxidation and inflammation. These systems are also involved in Alzheimer's disease, atherosclerosis and glomerulonephritis. Understanding commonalities of these four diseases may provide insight into AMD etiology. OBJECTIVES To understand AMD pathogenesis by analogy and suggest ideas for future research, this study summarizes main commonalities in disease pathogenesis of AMD, Alzheimer's disease, atherosclerosis and glomerulonephritis. METHODS Articles were identified through PubMed, Ovid Medline and Google Scholar. We summarized the common findings and synthesized critical differences. RESULTS Oxidation, lipid deposition, complement activation, and macrophage recruitment are involved in all four diseases shown by genetic, molecular, animal and human studies. Shared genetic variations further strengthen their connection. Potential areas for future research are suggested throughout the review. CONCLUSIONS The four diseases share many steps of an overall framework of pathogenesis. Various oxidative sources cause oxidative stress. Oxidized lipids and related molecules accumulate and lead to complement activation, macrophage recruitment and pathology. Investigations that arise under this structure may aid us to better understand AMD pathology.

IMPORTANCE Off-label antipsychotic prescribing in nursing homes (NHs) is common and is associated with increased risk of mortality in older adults. Prior large-scale, controlled trials in the NH setting failed to show meaningful reductions in antipsychotic use. OBJECTIVE To quantify the influence of a large-scale communication training program on NH antipsychotic use called OASIS. DESIGN, SETTING, AND PARTICIPANTS This investigation was a quasi-experimental longitudinal study of NHs in Massachusetts enrolled in the OASIS intervention. Participants were residents living in NHs between March 1, 2011, and August 31, 2013. The data were analyzed from December 2015, to March 2016, and from November through December 2016. EXPOSURES The OASIS educational program targets all NH staff (direct care and nondirect care) using a train-the-trainer model. The program goals were to reframe challenging behaviors of residents with cognitive impairment as the communication of unmet needs, to train staff to anticipate resident needs, and to integrate resident strengths into daily care plans. MAIN OUTCOMES AND MEASURES This study used an interrupted time series model of facility-level prevalence of antipsychotic medication use, other psychotropic medication use (antidepressants, anxiolytics, and hypnotics), and behavioral disturbances to evaluate the intervention's effectiveness in participating facilities compared with control NHs in Massachusetts and New York. The 18-month preintervention (baseline) period was compared with a 3-month training period, a 6-month implementation period, and a 3-month maintenance period. RESULTS This study included 93 NHs enrolled in the OASIS intervention (27 of which had a high prevalence of antipsychotic use) compared with 831 nonintervention NHs. Among OASIS facilities, prevalences of atypical antipsychotic prescribing were 34.1% at baseline and 26.5% at the study end (absolute reduction of 7.6% and relative reduction of 22.3%) compared with a drop of 22.7% to 18.8% in the comparison facilities (absolute reduction of 3.9% and relative reduction of 17.2%). In the OASIS implementation phase, NHs experienced a reduction in antipsychotic use prevalence among OASIS facilities (-1.20%; 95% CI, -1.85% to -0.09% per quarter) greater than that among non-OASIS facilities (-0.23%; 95% CI, -0.47% to 0.01% per quarter), resulting in a net OASIS influence of -0.97% (95% CI, -1.85% to -0.09%; P = .03). A difference in trend was not sustained in the maintenance phase (difference of 0.93%; 95% CI, -0.66% to 2.54%; P = .48). No increases in other psychotropic medication use or behavioral disturbances were observed. CONCLUSIONS AND RELEVANCE Antipsychotic use prevalence declined during OASIS implementation of the intervention, but the decreases did not continue in the maintenance phase. Other psychotropic medication use and behavioral disturbances did not increase. This study adds evidence for nonpharmacological programs to treat behavioral and psychological symptoms of dementia.

Abstract
Dementia, which can be induced by diverse factors, is a clinical syndrome characterized by the decline of cognitive function. Behavioral and psychological symptoms of dementia (BPSD) include depression, agitation, and aggression. Dementia causes a heavy burden on patients and their caregivers. Patients with BPSD should be assessed comprehensively by practitioners and offered appropriate non-pharmacologic and pharmacologic therapy. Non-pharmacologic therapy has been recommended as the basal treatment for BPSD; however, pharmacologic therapy is required under many situations. Medications, including antipsychotic agents, antidepressants, sedative and hypnotic agents, mood stabilizers, cholinesterase inhibitors, and amantadine, are extensively used in clinical practice. We have reviewed the progression of pharmacologic therapy for BPSD.

Abstract
OBJECTIVES To evaluate the effectiveness of efforts to translate and disseminate evidence-based guidelines about atypical antipsychotic use to nursing homes (NHs). DESIGN Three-arm, cluster randomized trial. SETTING NHs. PARTICIPANTS NHs in the state of Connecticut. MEASUREMENTS Evidence-based guidelines for atypical antipsychotic prescribing were translated into a toolkit targeting NH stakeholders, and 42 NHs were recruited and randomized to one of three toolkit dissemination strategies: mailed toolkit delivery (minimal intensity); mailed toolkit delivery with quarterly audit and feedback reports about facility-level antipsychotic prescribing (moderate intensity); and in-person toolkit delivery with academic detailing, on-site behavioral management training, and quarterly audit and feedback reports (high intensity). Outcomes were evaluated using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework. RESULTS Toolkit awareness of 30% (7/23) of leadership of low-intensity NHs, 54% (19/35) of moderate-intensity NHs, and 82% (18/22) of high-intensity NHs reflected adoption and implementation of the intervention. Highest levels of use and knowledge among direct care staff were reported in high-intensity NHs. Antipsychotic prescribing levels declined during the study period, but there were no statistically significant differences between study arms or from secular trends. CONCLUSION RE-AIM indicators suggest some success in disseminating the toolkit and differences in reach, adoption, and implementation according to dissemination strategy but no measurable effect on antipsychotic prescribing trends. Further dissemination to external stakeholders such as psychiatry consultants and hospitals may be needed to influence antipsychotic prescribing for NH residents.

Abstract
BACKGROUND In Alzheimer's disease, growing evidence has shown that uncontrolled glial activation and neuroinflammation may contribute independently to neurodegeneration. Antiinflammatory strategies might provide benefits for this devastating disease. The aims of the present study are to address the issue of whether glial activation and proinflammatory cytokine increases could be modulated by quetiapine in vivo and in vitro and to explore the underlying mechanism. METHODS Four-month-old amyloid precursor protein (APP) and presenilin 1 (PS1) transgenic and nontransgenic mice were treated with quetiapine (5mg/kg/d) in drinking water for 8 months. Animal behaviors, total Aβ levels, and glial activation were evaluated by behavioral tests, enzyme-linked immunosorbent assay, immunohistochemistry, and Western blot accordingly. Inflammatory cytokines and the nuclear factor kappa B pathway were analyzed in vivo and in vitro. RESULTS Quetiapine improves behavioral performance, marginally affects total Aβ40 and Aβ42 levels, attenuates glial activation, and reduces proinflammatory cytokines in APP/PS1 mice. Quetiapine suppresses Aβ1-42-induced activation of primary microglia by decresing proinflammatory cytokines. Quetiapine inhibits the activation of nuclear factor kappa B p65 pathway in both transgenic mice and primary microglia stimulated by Aβ1-42. CONCLUSIONS The antiinflammatory effects of quetiapine in Alzheimer's disease may be involved in the nuclear factor kappa B pathway. Quetiapine may be an efficacious and promising treatment for Alzheimer's disease targeting on neuroinflammation.

Abstract
Dementia is a clinical syndrome with features of neurocognitive decline. Subtypes of dementia include Alzheimer's, frontotemporal, Parkinson's, Lewy body disease, and vascular type. Dementia is associated with a variety of neuropsychiatric symptoms that may include agitation, psychosis, depression, and apathy. These symptoms can lead to dangerousness to self or others and are the main source for caregiver burnout. Treatment of these symptoms consists of nonpharmacological and pharmacological interventions. However, there are no Food and Drug Administration-approved medications for the treatment of behavioral and psychological symptoms of dementia. Pharmacological interventions are used off-label. This article reviews the current evidence supporting or negating the use of psychotropic medications along with safety concerns, monitoring, regulations, and recommendations.

Abstract
BACKGROUND/OBJECTIVES Antipsychotic use is common in US nursing homes, despite evidence of increased risk of morbidity and mortality, and limited efficacy in older adults with dementia. Knowledge, attitudes, and beliefs regarding antipsychotic use among nursing home staff are unclear. The study aim was to describe nursing home leadership and direct care staff members' knowledge of antipsychotic risks, beliefs and attitudes about the effectiveness of antipsychotics and nonpharmacologic management of dementia-related behaviors, and perceived need for evidence-based training about antipsychotic medication safety. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS Survey of leadership and direct care staff of nursing homes in Connecticut was conducted in June 2011. Questionnaire domains included knowledge of antipsychotic risks, attitudes about caring for residents with dementia, satisfaction with current behavior management training, beliefs about antipsychotic effectiveness, and need for staff training about antipsychotics and behavior management. RESULTS A total of 138 nursing home leaders and 779 direct care staff provided useable questionnaires. Only 24% of nursing home leaders identified at least 1 severe adverse effect of antipsychotics; 13% of LPNs and 12% of RNs listed at least 1 severe adverse effect. Fifty-six percent of direct care staff believed that medications worked well to manage resident behavior. Leaders were satisfied with the training that staff received to manage residents with challenging behaviors (62%). Fifty-five percent of direct care staff felt that they had enough training on how to handle difficult residents; only 37% felt they could do so without using medications. CONCLUSIONS Findings suggest that a comprehensive multifaceted intervention designed for nursing homes should aim to improve knowledge of antipsychotic medication risks, change beliefs about appropriateness and effectiveness of antipsychotics for behavior management, and impart strategies and approaches for nonpharmacologic behavior management.

Abstract
PURPOSE To evaluate the effect of a broad range of covariates on the survival of a real-life long-term follow-up cohort of community-dwelling patients with behavioural and psychological symptoms of dementia who were new users of atypical antipsychotic medications (APMs). METHODS This was a prospective cohort study of 1,618 subjects aged ≥65 years with dementia and BPSD ("behavioural and psychological symptoms of dementia") who were new users of atypical APMs and registered in a Dementia Evaluation Unit of Campania Region (Italy) from September 2006 to March 2010. The potential of baseline features to predict mortality was assessed with the Cox proportional hazards model. RESULTS The average follow-up was 309 days. Of the 1,618 new users of atypical antipsychotics, 9.3 % experienced at least one adverse event, including death (5.1 %), drug therapeutic failure (3.0 %), extrapyramidal symptoms (0.5 %) and stroke (0.2 %). The crude all-cause mortality rate was 6.0 per 100 person-years [95 % confidence interval (CI) 4.8-7.4]; the rate was higher in patients aged >85 years (9.0 per 100 person-years, 95 % CI 6.4-12.7) and among male patients (7.5 per 100 person-years, 95% CI 5.3-10.6). In the multivariate analysis, only age was associated to all-cause mortality [hazard ratio (HR) 1.1; 95 % CI 1.0-1.1 and HR 1.4; 95 % CI: 0.9-2.2, respectively). In contrast, hallucination (HR 0.4; 95 % CI 0.2-0.6) and dosage change (HR 0.4; 95 % CI 0.2-0.78) were significantly associated with a lower risk of all-cause mortality. CONCLUSIONS Among our patient cohort, the mortality rate of patients with BPSD receiving long-term treatment with atypical APMs was lower than that reported in other studies, and only age was found to be significant predictor factor of mortality.

Abstract
Dementia has become an all-important disease because the population is aging rapidly and the cost of health care associated with dementia is ever increasing. In addition to cognitive function impairment, associated behavioral and psychological symptoms of dementia (BPSD) worsen patient’s quality of life and increase caregiver’s burden. Alzheimer’s disease is the most common type of dementia and both behavioral disturbance and cognitive impairment of Alzheimer’s disease are thought to be associated with the N-methyl-D-aspartate (NMDA) dysfunction as increasing evidence of dysfunctional glutamatergic neurotransmission had been reported in behavioral changes and cognitive decline in Alzheimer’s disease. We review the literature regarding dementia (especially Alzheimer’s disease), BPSD and relevant findings on glutamatergic and NMDA neurotransmission, including the effects of memantine, a NMDA receptor antagonist, and NMDA-enhancing agents, such as D-serine and D-cycloserine. Literatures suggest that behavioral disturbance and cognitive impairment of Alzheimer’s disease may be associated with excitatory neurotoxic effects which result in impairment of neuronal plasticity and degenerative processes. Memantine shows benefits in improving cognition, function, agitation/aggression and delusion in Alzheimer’s disease. On the other hand, some NMDA modulators which enhance NMDA function through the co-agonist binding site can also improve cognitive function and psychotic symptoms. We propose that modulating NMDA neurotransmission is effective in treating behavioral and psychological symptoms of Alzheimer’s disease. Prospective study using NMDA enhancers in patients with Alzheimer’s disease and associated behavioral disturbance is needed to verify this hypothesis.

Abstract
OBJECTIVE To compare physicians (MDs), psychologists (PhDs), and nurse practitioners (NPs) regarding their approach to dementia-associated behavior problems in nursing home residents. METHODS A web-based questionnaire solicited information about symptoms, assessment methods, suspected etiologies, and interventions with respect to the last resident treated for dementia-associated behavior problems. RESULTS Responses were obtained from 108 MDs, 38 PhDs, and 100 NPs. All groups relied similarly on information from the nursing staff, speaking with nursing assistants, and care team meetings in assessment; NPs were more likely to consult with family members. A standard assessment instrument was used most frequently by PhDs (50%), but this generally assessed cognitive status rather than problem behaviors. PhDs most frequently noted depression in residents. Groups were similar in attributing the behavioral symptoms to dementia and to underlying medical conditions, but PhDs were more likely to indicate depression, loneliness/boredom, staff-resident communication, and insufficient activities as etiologies. Use of pharmacological and nonpharmacological interventions of MDs and NPs were similar. PhDs reported least satisfaction with treatment. CONCLUSION Awareness of similarities and differences in the approaches of different health professionals can facilitate interdisciplinary interaction in providing care for dementia-associated behavior problems in nursing home residents.

Abstract
PURPOSE OF THE STUDY Behavior problems are common in nursing homes. Current guidelines recommend nonpharmacological interventions (NPHIs) as first-line treatment, but pharmacological regimens (PIs) continue to be used. Given differences in background and training of those who treat behavior problems in residents, we compared attitudes of physicians (MDs), psychologists (PhDs), and nurse practitioners (NPs) concerning PI and NPHI usage as well as knowledge of NPHIs. DESIGN AND METHODS One hundred and eight MDs, 36 PhDs, and 89 NPs responded to a web-based questionnaire that captured level of agreement with statements concerning treatment of behavior symptoms and familiarity with NPHIs. RESULTS NPs were the most favorable toward NPHIs. MDs were significantly more favorable to the use of PIs than were PhDs, with attitudes of NPs falling in between. All felt that NPHI usage should increase and that NPHIs should be implemented before using PIs but also believed that PIs work well for behavior problems. MDs had significantly lower knowledge of NPHIs than PhDs or NPs. Overall, NPHI knowledge was similar for PhDs and NPs, although they differed on their use of specific interventions. IMPLICATIONS As levels of knowledge and familiarity with NPHIs differed among providers, it is conceivable that all might benefit from training and experience with a wider range of NPHIs. Future studies might evaluate the impact of a uniform understanding of NPHI on communication and teamwork in nursing homes and examine ways to enhance a multidisciplinary approach that would allow for the tailoring and individualization that is required of successful interventions.

Abstract
This article reports the recommendations of the Scientific Department of Cognitive Neurology and Aging of the Brazilian Academy of Neurology for the treatment of Alzheimer's disease (AD) in Brazil, with special focus on behavioral and psychological symptoms of dementia (BPSD). It constitutes a revision and broadening of the 2005 guidelines based on a consensus involving researchers (physicians and non-physicians) in the field. The authors carried out a search of articles published since 2005 on the MEDLINE, LILACS and Cochrane Library databases. The search criteria were pharmacological and non-pharmacological treatment of the behavioral and psychological symptoms of AD. Studies retrieved were categorized into four classes, and evidence into four levels, based on the 2008 recommendations of the American Academy of Neurology. The recommendations on therapy are pertinent to the dementia phase of AD. Recommendations are proposed for the treatment of BPSD encompassing both pharmacological (including acetyl-cholinesterase inhibitors, memantine, neuroleptics, anti-depressives, benzodiazepines, anti-convulsants plus other drugs and substances) and non-pharmacological (including education-based interventions, physiotherapy, occupational therapy, music therapy, therapy using light, massage and art therapy) approaches. Recommendations for the treatment of cognitive disorders of AD symptoms are included in a separate article of this edition.

Abstract
OBJECTIVES To assess the relative effect of different types of stimuli on agitated behaviors of nursing home residents with dementia. DESIGN Repeated-measures design with randomized assignment of conditions. SETTING Seven Maryland nursing homes. PARTICIPANTS One hundred eleven nursing home residents with a diagnosis of dementia who exhibited agitation. INTERVENTION Different types of stimuli (music, social stimuli, simulated social stimuli, and individualized stimuli based on the person's self-identity) were presented. MEASUREMENTS Agitation was directly observed and recorded using the Agitation Behavior Mapping Instrument. RESULTS All stimulus categories were associated with significantly less physical agitation than baseline observations, and all except for manipulative stimuli were associated with significantly less total agitation. Live social stimuli were associated with less agitation than music, self-identity, work, simulated social, and manipulative stimulus categories. Task and reading stimulus categories were each associated with significantly less agitation than work, simulated social, and manipulative stimulus categories. Music and self-identity stimuli were associated with less agitation than simulated social and manipulative stimuli. CONCLUSION Providing stimuli offers a proactive approach to preventing agitation in persons with dementia, with live social stimuli being the most successful.

Abstract
Delusions, hallucinations and other psychotic symptoms can accompany a number of conditions in late life. As such, elderly patients are commonly prescribed antipsychotic medications for the treatment of psychosis in both acute and chronic conditions. Those conditions include schizophrenia, bipolar disorder, depression and dementia. Elderly patients are at an increased risk of adverse events from antipsychotic medications because of age-related pharmacodynamic and pharmacokinetic changes as well as polypharmacy. Drug selection should be individualized to the patient's previous history of antipsychotic use, current medical conditions, potential drug interactions, and potential side effects of the antipsychotic. Specifically, metabolic side effects should be closely monitored in this population. This paper provides a review of aripiprazole, a newer second generation antipsychotic agent, for its use in a variety of psychiatric disorders in the elderly including schizophrenia, bipolar disorder, dementia, Parkinson's disease and depression. We will review the pharmacokinetics and pharmacodynamics of aripiprazole as well as dosing, diagnostic indications, efficacy studies, and tolerability including its metabolic profile. We will also detail patient focused perspectives including quality of life, patient satisfaction and adherence.

Abstract
Psychotropic medications are commonly administered to elderly clients to manage behavior and psychiatric symptoms. These drugs are known to have potentially serious side effects, to which older adults are more vulnerable. Nurses care for older adults in many different practice settings but have varying degrees of knowledge about these kinds of medications. The purposes of this article are to (a) provide information to geriatric nurses in all settings about how the most commonly prescribed psychotropic medications (i.e., anxiolytic, antidepressant, and antipsychotic drugs) differentially affect older adults; (b) examine recent concerns about the use of psychotropic medications with older adults; and (c) discuss nursing implications for those administering psychotropic medications to older adults.

Abstract
OBJECTIVE Patients with dementia in 2 German community psychiatric hospitals with different treatment settings were investigated prospectively and treatment variables compared. METHOD In each of the hospitals, which differ in treatment settings (Gütersloh specialized vs. Detmold integrated), 50 patients with dementia consecutively admitted were screened and compared according to personal data, clinical instruments, medication, and diagnosis. RESULTS No relevant differences were found in the basic characteristics, average age was high (79 years), and patients were significantly restrained in functionality and cognitive functioning. Patients of Gütersloh were transferred to institutional care less frequently. Overall morbidity was high and little improvement in functioning at discharge was recorded. CONCLUSIONS Data of this prospective study show that dementia patients were significantly restrained in cognitive and daily functioning along with high morbidity. Discharge to institutional care and discharge medication was reduced in patients of the special dementia care setting.

Abstract
INTRODUCTION Although there is evidence for distinct behavioural sub-phenotypes in Alzheimer's disease (AD), their inter-relationships and the effect of clinical variables on their expression have been little investigated. METHODS We have analysed a sample of 1850 probable AD patients from the UK and Greece with 10 item Neuropsychiatric Inventory (NPI) data. We applied a Multiple Indicators Multiple Causes (MIMIC) approach to investigate the effect of MMSE, disease duration, gender, age and age of onset on the structure of a four-factor model consisting of "psychosis", "moods", "agitation" and "behavioural dyscontrol". RESULTS Specific clinical variables predicted the expression of individual factors. When the inter-relationship of factors is modelled, some previously significant associations are lost. For example, lower MMSE scores predict psychosis, agitation and behavioural dyscontrol factors, but psychosis and mood predict the agitation factor. Taking these associations into account MMSE scores did not predict agitation. CONCLUSIONS The complexity of the inter-relations between symptoms, factors and clinical variables is efficiently captured by this MIMIC model.

Abstract
Antipsychotic drugs are divided into two groups: typical and atypical. Recent clinical studies show atypical antipsychotics have advantages over typical antipsychotics in a wide variety of neuropsychiatric conditions, in terms of greater efficacy for positive and negative symptoms, beneficial effects on cognitive functioning, and fewer extra pyramidal side effects in treating schizophrenia. As such, atypical antipsychotics may be effective in the treatment of depressive symptoms associated with psychotic and mood disorders, posttraumatic stress disorder and psychosis in Alzheimer disease. In this paper, we describe the effects and potential neurochemical mechanisms of action of atypical antipsychotics in several animal models showing memory impairments and/or non-cognitive behavioral changes. The data provide new insights into the mechanisms of action of atypical antipsychotics that may broaden their clinical applications.

Abstract
Psychosis of Alzheimer's disease (AD) is characterized by delusions or hallucinations and may be associated with agitation, negative symptoms or depression. There are no psychotropic medications that are approved by the US FDA for the treatment of psychosis of AD. However, atypical antipsychotics have been widely used and recommended by geriatric experts in the management of psychosis of AD in view of the modest efficacy and relative safety until FDA warnings were issued in 2005 and meta-analytic studies showed no significant difference to placebo. The FDA warnings on the cardiac, metabolic, cerebrovascular, and mortality risks have caused serious concerns for the use of atypical antipsychotic agents in elderly patients with dementia. Only a few studies have evaluated prospectively the effects of aripiprazole in psychosis associated with AD. These studies show improvement in the symptoms of psychosis associated with AD with aripiprazole. The safety and tolerability profile of aripiprazole suggests a low potential for negative impact on dementia and overall patient health. Further studies comparing the efficacy and tolerability of aripiprazole vs other atypical antipsychotics in dementia are needed.
