Abstract
BACKGROUND Evidence on the differences in depressive symptoms among older adults with multiple chronic conditions (MCCs) in urban and rural areas is limited. METHODS Measures of depressive symptoms (Center for Epidemiologic Studies Depression Scale-10) and demographic factors (age, gender, and urban-rural distribution) were used. RESULTS A total of 4021 older adults with MCCs were included in this study. Significant differences were observed in both network global strength (Urban: 3.989 vs. Rural: 3.703, S = 0.286, p = 0.003) and network structure (M = 0.139, p = 0.002) between urban and rural residents. CONCLUSIONS The study highlights the need for region-specific approaches to understanding and addressing depression and holds the potential to enhance understanding of the psychological health status of older adults with MCCs in urban and rural settings.

Abstract
The main aim of the present study is to evaluate the influence of depressive symptoms on mortality in patients with SCD (subjective cognitive decline), naMCI (non-amnestic mild cognitive impairment), and aMCI (amnestic mild cognitive impairment). Additional factors (age, sex, years of school attendance, and neuropsychological performance) were considered to determine the impact on survival probability. A monocentric retrospective data analysis based on adjusted patient protocols (n = 1221) from the observation period 1998-2021, using the Cox Proportional Hazards model, assessed whether depressivity had an explanatory value for survival, considering SCD as the reference level in relation to naMCI and aMCI. Covariates were included blockwise. Cox regression revealed that depressiveness (Beck Depression Inventory, Geriatric Depression Scale) did not make a significant contribution as a risk factor for mortality in all five model blocks, BDI-II with HR 0.997 [0.978; 1.02] and GDS-15 with HR 1.03 [0.98; 1.08]. Increasing age with HR 1.09 [1.07; 1.11] and male sex with HR (inverted) 1.53 [1.17; 2.00] appeared as risk factors for increased mortality across all five model blocks. aMCI (vs. SCD) with HR 1.91 [1.33; 2.76] showed a significant explanatory value only up to the fourth model block. By adding the six dimensions of the Neuropsychological Test Battery Vienna in the fifth model block, the domains attention and perceptual speed with HR 1.34 [1.18; 1.53], and executive functions with HR 1.24 [1.11; 1.39], showed substantial explanatory values for survival. Accordingly, no tendency can be attributed to depressiveness as a risk factor on the probability of survival, whereas the influence of certain cognitive dimensions, especially attention and perceptual speed, and executive functions, can be seen as protective for survival.

Abstract
BACKGROUND There is a lack of instruments for measuring quality of life (QOL) in Chinese patients with mild cognitive impairment (MCI). This study aimed to translate the Mild Cognitive Questionnaire (MCQ) into the Chinese language and to evaluate the reliability and construct validity of the MCQ-Chinese among older adults with MCI. METHODS Linguistic translation and validation of the questionnaire were conducted according to the MCQ developer and Oxford University Innovation guidelines. After a pilot test, the final version of the MCQ-Chinese was applied to a convenience sample of older adults with MCI (n = 186). Cronbach's alpha and confirmatory factor analyses were used to assess the reliability and construct validity of the MCQ-Chinese. In addition, non-parametric analysis was used to assess convergent and discriminant validity. RESULTS The total scale and all the factors had good internal consistency, with Cronbach's alpha values ranging from 0.90 to 0.92. Confirmatory factor analysis indicated satisfactory goodness of fit for the 2-factor MCQ. The MCQ-Chinese had a good convergent validity, and the discriminant validity was confirmed with a significant difference in MCQ scores in different health conditions. CONCLUSIONS MCQ-Chinese is a reliable tool for assessing QOL among Chinese older adults with MCI.

Abstract
OBJECTIVES Depressive symptoms are common among mild cognitive impairment (MCI) patients. It is unknown how different the effects on depressive symptoms are among various pharmacological MCI interventions. This systematic review aimed to evaluate the comparative effectiveness of non-pharmacological MCI interventions on depressive symptoms among MCI patients. METHODS A systematic review and network meta-analysis was conducted on randomized controlled trials (RCT) comparing the effect of different non-pharmacological MCI interventions on changes in depressive symptoms among MCI patients. RCTs were identified from MEDLINE, EMBASE, Cochrane Library, CINAHL, PsycINFO, and PsycARTICLES. Results were summarized as standardized mean differences (SMD) and 95% confidence intervals (CI). The surface under the cumulative ranking (SUCRA) was used to rank the effect of different interventions. RESULTS Twenty-two RCTs were included in the network meta-analysis. Compared with non-active control, cognition-based intervention (SMD=-0.25, 95% CI: -0.46, -0.04) and physical exercise (SMD=-0.33, 95% CI: -0.56, -0.10) had significant positive effects to reduce depressive symptoms. Health education, psychosocial intervention, and the combination of physical exercise and cognition-based intervention had non-significant overall effects. The SUCRA demonstrated that physical exercise had the highest SUCRA for the reduction in depression symptoms (0.815). In subgroup analysis, health education, cognition-based intervention, physical exercise, and the combination of physical exercise and cognition-based intervention showed significant longer-term effects (6-12 months). CONCLUSION Physical exercise and cognition-based intervention were effective interventions for depressive symptoms in MCI patients. This study can provide additional evidence for healthcare providers to make decisions for selecting available and appropriate interventions for MCI patients.

Abstract
The objective of this study was to estimate the joint effects of cognitive impairment and depressive symptoms on health-related quality of life (HRQoL) and to explore the mediating role of disability among Chinese community-dwelling older adults. A cross-sectional study was conducted with 2525 community-dwelling older adults aged ≥60 years and living in Shanghai, China in 2019. Participants were divided into four groups: (1) non-depressed without dementia, (2) non-depressed with probable MCI, (3) depressed without dementia and (4) depressed with probable mild cognitive impairment (MCI). HRQoL was assessed using the 36-Item Short-Form Health Survey. Cognitive impairment and depressive symptoms were evaluated with the AD8 and the Geriatric Depression Scale respectively. Activities of daily living (ADL) and instrumental activities of daily living (IADL) disability and other sociodemographic variables were also assessed. The results of this study showed that controlling for sociodemographic characteristics, significant differences in a physical component score (PCS) and a mental component score (MCS) of HRQoL were found across the four groups. Compared to those who were non-depressed without dementia, older adults who were depressed with probable MCI reported the lowest level of PCS and MCS, followed by older adults who were depressed without dementia. Both ADL and IADL disabilities played mediating roles in the relationship between cognitive impairment and depressive symptoms and PCS. Based on this study, we suggest that the early detection and adequate management of depressive symptoms and cognitive status-as well as efforts to improve individuals' ability to manage their ADLs and IADLs-may help to maintain or improve their HRQoL.

Abstract
Background: There is a need to better understand the experience of patients living with Alzheimer's disease (AD) in the early stages. Objective: The aim of the study was to evaluate the perception of quality of life in patients with early-stage AD. Methods: A multicenter, non-interventional study was conducted including patients of 50–90 years of age with prodromal or mild AD, a Mini-Mental State Examination (MMSE) score ≥22, and a Clinical Dementia Rating-Global score (CDR-GS) of 0.5.–1.0. The Quality of Life in Alzheimer ’s Disease (QoL-AD) questionnaire was used to assess health-related quality of life. A battery of self-report instruments was used to evaluate different psychological and behavioral domains. Associations between the QoL-AD and other outcome measures were analyzed using Spearman’s rank correlations. Results: A total of 149 patients were included. Mean age (SD) was 72.3 (7.0) years and mean disease duration was 1.4 (1.8) years. Mean MMSE score was 24.6 (2.1). The mean QoL-AD score was 37.9 (4.5). Eighty-three percent (n = 124) of patients had moderate-to-severe hopelessness, 22.1% (n = 33) had depressive symptoms, and 36.9% (n = 55) felt stigmatized. The quality of life showed a significant positive correlation with self-efficacy and negative correlations with depression, emotional and practical consequences, stigma, and hopelessness. Conclusion: Stigma, depressive symptoms, and hopelessness are frequent scenarios in AD negatively impacting quality of life, even in a population with short disease duration and minimal cognitive impairment.

Abstract
Background: The association between health-related quality of life (HRQoL) and care costs in people at risk for cognitive decline is not well understood. Studying this association could reveal the potential benefits of increasing HRQoL and reducing care costs by improving cognition. Objective: In this exploratory data analysis we investigated the association between cognition, HRQoL utilities and costs in a well-functioning population at risk for cognitive decline. Methods: An exploratory data analysis was conducted using longitudinal 2-year data from the FINGER study (n = 1,120). A change score analysis was applied using HRQoL utilities and total medical care costs as outcome. HRQoL utilities were derived from the Short Form Health Survey-36 (SF-36). Total care costs comprised visits to a general practitioner, medical specialist, nurse, and days at hospital. Analyses were adjusted for activities of daily living (ADL) and depressive symptoms. Results: Although univariable analysis showed an association between cognition and HRQoL utilities, multivariable analysis showed no association between cognition, HRQoL utilities and total care costs. A one-unit increase in ADL limitations was associated with a -0.006 (p < 0.001) decrease in HRQoL utilities and a one-unit increase in depressive symptoms was associated with a -0.004 (p < 0.001) decrease in HRQoL utilities. Conclusion: The level of cognition in people at-risk for cognitive decline does not seem to be associated with HRQoL utilities. Future research should examine the level at which cognitive decline starts to affect HRQoL and care costs. Ideally, this would be done by means of cross-validation in populations with various stages of cognitive functioning and decline.

Abstract
Alzheimer's disease (AD) is the leading cause of cognitive impairment and dementia in older individuals (aged ≥ 65 years) throughout the world. As a result of these progressive deficits in cognitive, emotional, and physical function, AD dementia can cause functional disability and loss of independence. To gain a deeper understanding of the recent literature on the burden of AD, including that of mild cognitive impairment (MCI) due to AD, we conducted a comprehensive targeted review of the PubMed-indexed literature (2014 to 2021) to examine the humanistic and economic burden of AD (including MCI) in North America, Europe, and Asia. Our literature review identified a range of factors associated with quality of life (QoL): some factors were positively associated with QoL, including caregiver relationship, religiosity, social engagement, and ability to engage in activities of daily living (ADL), whereas other factors such as neuropsychiatric symptoms were associated with poorer QoL. While patient- and proxy-rated QoL are highly correlated in patients with early AD dementia, proxy-rated QoL declines more substantially as severity worsens. The maintenance of self-reported QoL in patients with more severe AD dementia may be due to lack of awareness or to adaptation to circumstances. Compared to persons with normal cognition, MCI is associated with a greater cost burden, and individuals with MCI exhibit worse QoL. Key drivers of the societal economic burden of AD include disease severity, dependence level, institutionalization, and comorbidity burden. Evaluation of the impact of a hypothetical disease-modifying treatment delaying the progression from MCI to AD has suggested that such a treatment may result in cost savings.

Abstract
BACKGROUND Acoustic Neuroma (AN) is a benign tumour of the eighth cranial nerve. Stereotactic Radiosurgery (SRS) is a common treatment approach. Studies have explored the primary effects of SRS and documented equivalent efficacy for tumour control compared to neurosurgery. OBJECTIVE Examine the longer term cognitive and psychosocial outcomes of SRS in non-Neurofibromatosis Type II patients utilising both objective and subjective cognitive outcomes associated with quality of life and health related distress. METHODS Nineteen individuals treated via SRS were assessed using a battery of standardised psychometric tests as well as measures of quality of life and psychological distress. RESULTS Participants had largely preserved cognitive function except for processing speed, aspects of attention and visual memory relative to age norms. Self-reported quality of life was better than in other AN population studies. Level of psychological distress was equivalent to general population norms. More than half of participants reported subjective cognitive decline though this was not fully supported by objective testing. Subjective cognitive complaints may be associated with lower reported quality of life. CONCLUSIONS Results are largely consistent with previous findings on the effects of SRS in other clinical groups, which supports SRS as a targeted radiation treatment for AN.

Abstract
Objectives: Older adults commonly report problems with their memory which can elicit sadness and worry about future development of cognitive impairment. Conversely, ongoing depressive symptoms can negatively impact older adults' perceptions of their memory performance. The current study examined the longitudinal associations between self-reported memory problems and depressive symptoms to explore which symptom tends to appear first.Method: Two datasets from ongoing observational, longitudinal studies of aging (Memory and Aging Project; Minority Aging Research Study) were used for secondary analyses. Older adults (n = 1,724; Mage = 77.03; SD = 7.54; 76.80% female; 32.26% Black) completed up to 18 annual assessments of self-reported memory (two items: perceived decline in memory and frequency of memory problems) and depressive symptoms. Multilevel models were used to examine intra-individual variability and time-lagged relationships between self-reported memory and depressive symptoms.Results: Concurrently, self-reported memory problems and depressive symptoms were significantly related; at times when older adults reported poorer memory, they also reported more depressive symptoms, regardless of the type of memory self-report. Prospectively, perceived memory decline predicted future depressive symptoms, but depressive symptoms did not predict future reports of memory decline. Self-reported frequency of memory problems did not predict future depressive symptoms or vice versa.Conclusion: The current study's findings suggest a temporal relationship between perceived memory decline and depressive symptoms, such that perceived memory decline can lead to future depressive symptoms. These findings can inform future studies focused on developing a standardized assessment of self-reported memory that is separable from depressive symptoms.

Abstract
The results of neuropsychological tests may be distorted by patients who exaggerate cognitive deficits. Eighty-three patients with cognitive deficit [Amnestic Mild Cognitive Impairment (aMCI), n = 53; Alzheimer's disease (AD) dementia, n = 30], 44 healthy older adults (HA), and 30 simulators of AD (s-AD) underwent comprehensive neuropsychological assessment. Receiver Operating Characteristic (ROC) analysis revealed high specificity but low sensitivity of the Delayed Matching to Sample Task (DMS48) in differentiating s-AD from AD dementia (87 and 53%, respectively) and from aMCI (96 and 57%). The sensitivity was considerably increased by using the DMS48/Rey Auditory Verbal Learning Test (RAVLT) ratio (specificity and sensitivity 93% and 93% for AD dementia and 96% and 80% for aMCI). The DMS48 differentiates s-AD from both aMCI and AD dementia with high specificity but low sensitivity. Its predictive value greatly increased when evaluated together with the RAVLT.

Abstract
While it is generally understood that Alzheimer’s disease (AD) and related dementias (ADRD) is one of the costliest diseases to society, there is widespread concern that researchers and policymakers are not comprehensively capturing and describing the full scope and magnitude of the socioeconomic burden of ADRD. This review aimed to 1) catalogue the different types of AD-related socioeconomic costs described in the literature; 2) assess the challenges and gaps of existing approaches to measuring these costs; and 3) analyze and discuss the implications for stakeholders including policymakers, healthcare systems, associations, advocacy groups, clinicians, and researchers looking to improve the ability to generate reliable data that can guide evidence-based decision making. A centrally emergent theme from this review is that it is challenging to gauge the true value of policies, programs, or interventions in the ADRD arena given the long-term, progressive nature of the disease, its insidious socioeconomic impact beyond the patient and the formal healthcare system, and the complexities and current deficiencies (in measures and real-world data) in accurately calculating the full costs to society. There is therefore an urgent need for all stakeholders to establish a common understanding of the challenges in evaluating the full cost of ADRD and define approaches that allow us to measure these costs more accurately, with a view to prioritizing evidence-based solutions to mitigate this looming public health crisis.

Abstract
BACKGROUND Depression is common in people with cognitive impairment but the effect of cognitive training in the reduction of depression is still uncertain. AIMS The purpose of this paper is to evaluate the effect of cognitive training interventions in the reduction of depression rating scale score in people with cognitive impairment. METHODS Literature searches were conducted via OVID databases. Randomized controlled trials (RCTs) evaluated the effect of cognitive training interventions for the reduction of depression rating scale score in people with mild cognitive impairment (MCI) or dementia were included. Mean difference (MD) with 95% confidence interval (CI) was used to combine the results of Geriatric Depression Scale (GDS). Standardized mean difference (SMD) was used to combine the results of different depression rating scales. Subgroup analyses were conducted according to the types of cognitive training and severity of cognitive impairment, i.e. MCI and dementia. RESULTS A total of 2551 people with MCI or dementia were extracted from 36 RCTs. The baseline mean score of GDS-15 was 4.83. Participants received cognitive training interventions had a significant decrease in depression rating scale score than the control group (MD of GDS-15 = -1.30, 95% CI = -2.14--0.47; and SMD of eight depression scales was -0.54 (95% CI = -0.77--0.31). In subgroup analyses, the effect size of computerized cognitive training and cognitive stimulation therapy were medium-to-large and statistically significant in the reduction of depression rating scale score. CONCLUSIONS Cognitive training interventions show to be a potential treatment to ameliorate depression in people with cognitive impairment.

Abstract
PURPOSE Mild cognitive impairment (MCI) is a widespread phenomenon, especially affecting older individuals. We will analyze in how far MCI affects different facets of quality of life (QOL). METHODS We used a sample of 903 participants (110 with MCI) from the fifth follow-up of the German Study on Ageing, Cognition, and Dementia in Primary Care Patients (AgeCoDe), a prospective longitudinal study, to analyze the effects of MCI on different facets of the WHOQOL-OLD. We controlled for age, gender, marital status, education, living situation, daily living skills, and the ability to walk, see, and hear. RESULTS Univariate analyses showed that individuals with MCI exhibited lower QOL with regard to the facets autonomy; past, present, and future activities; social participation; and intimacy, but less fears related to death and dying. No significant difference was shown with regard to the facet sensory abilities. In multivariate analyses controlling for age, gender, marital status, education, living situation, daily living skills, and the ability to walk, see and hear, MCI-status was significantly associated with QOL in the facet autonomy. CONCLUSION Effects of MCI go beyond cognition and significantly impact the lives of those affected. Further research and practice will benefit from utilizing specific facets of QOL rather than a total score.

Abstract
We aimed to investigate sleep quality and health-related quality of life (HRQOL) in older adults with subjective cognitive decline (SCD), mild cognitive impairment (MCI), and Alzheimer disease (AD). A total of 221 participants were divided into the following five groups: normal controls (NCs), SCD without memory concerns (SCD-0), SCD with memory concerns (SCD-1), MCI, and AD according to their cognitive status. Compared with NC, individuals with SCD-0, SCD-1, MCI, and AD had more sleep problems and reduced HRQOL. Participants with poor sleep quality had an increased risk of cognitive impairment compared with participants with good sleep quality. Within all five subgroups, individuals with poor sleep quality reported more difficulties in HRQOL than individuals with good sleep quality. Future studies employing a longitudinal design, larger samples, and objective evaluation tools are needed.

Abstract
The prevalence of mild cognitive impairment (MCI) has significantly increased in recent years. No specific instruments are available in Spanish for assessing health-related quality of life (HRQoL) in people with MCI. The aim of this study was to adapt transculturally and validate the mild cognitive impairment questionnaire (MCQ) in Spanish people with MCI. A standardized transcultural adaptation process was carried out, and the structural equivalence of the Spanish version of the scale was examined. In addition, we studied the reliability and construct validity of the instrument. The sample comprised 100 people with MCI, with a mean age of 79.5 years. In a confirmatory factor analysis, we found the instrument had a one-factor structure and adequate internal consistency. Related to the construct validity, we found meaningful relationships with measures of HRQoL and depression. Our results indicate that the Spanish version of the MCQ is a reliable and valid tool for measuring HRQoL in Spanish patients with MCI. The availability of specific tools, such as the MCQ allows nurses to evaluate new intervention strategies to improve the HRQoL of these patients. Furthermore, this scale can be used by researchers and clinicians to improve the standards of care provided to this population.

Abstract
BACKGROUND Subjective cognitive complaints in cognitively normal adults have been linked to later cognitive decline and dementia. Research on the characteristics of this group has been conducted on a variety of clinical and community-based populations. The current study focuses on the rapidly expanding population of Mexican-American elders. OBJECTIVE The objective of the study is the determination of characteristics of cognitively normal Mexican-Americans with cognitive complaints. METHODS Data on 319 cognitively normal participants in a large-scale community-based study of elderly Mexican-Americans (HABLE) were analyzed comparing those with cognitive complaints with those without on clinical characteristics, affective status, neuropsychological functioning, and proteomic markers. RESULTS Those expressing concern about cognitive decline scored lower on the MMSE, were more likely to have significantly more affective symptoms, higher levels of diabetic markers, poorer performance on attention and executive functioning, and a different pattern of inflammatory markers. CONCLUSION Although longitudinal research is needed to determine the impact of these differences on later cognition, possible targets for early intervention with Mexican-Americans were identified.

Abstract
OBJECTIVES To assess changes in depressive symptoms and health-related quality of life (HRQOL) after screening for cognitive impairment in people with type 2 diabetes. DESIGN A prospective cohort study, part of the Cognitive Impairment in Diabetes (Cog-ID) study. SETTING Participants were screened for cognitive impairment in primary care. People suspected of cognitive impairment (screen positives) received a standardised evaluation at a memory clinic. PARTICIPANTS Participants ≥70 years with type 2 diabetes were included in Cog-ID between August 2012 and September 2014, the current study includes 179 patients; 39 screen positives with cognitive impairment, 56 screen positives without cognitive impairment and 84 participants not suspected of cognitive impairment during screening (screen negatives). OUTCOME MEASURES Depressive symptoms and HRQOL assessed with the Center for Epidemiologic Studies Depression Scale (CES-D), 36-Item Short-Form Health Survey, European Quality of Life-5 Dimensions questionnaire and the EuroQol Visual Analogue Scale. Outcomes were assessed before the screening, and 6 and 24 months after screening. An analysis of covariance model was fitted to assess differences in score changes among people diagnosed with cognitive impairment, screen negatives and screen positives without cognitive impairment using a factor group and baseline score as a covariate. RESULTS Of all participants, 60.3% was male, mean age was 76.3±5.0 years, mean diabetes duration 13.0±8.5 years. At screening, participants diagnosed with cognitive impairment had significantly more depressive symptoms and a worse HRQOL than screen negatives. Scores of both groups remained stable over time. Screen positives without cognitive impairment scored between the other two groups at screening, but their depressive symptoms decreased significantly during follow-up (mean CES-D: -3.1 after 6 and -2.1 after 24 months); their HRQOL also tended to improve. CONCLUSIONS Depressive symptoms are common in older people with type 2 diabetes. Screening for and a subsequent diagnosis of cognitive impairment will not increase depressive symptoms.

Abstract
Personality and dementia are connected in different ways. A broad knowledge about personality and prodromal stages of dementia might be helpful to identify dementia as early as possible. Hence, personality differences between three cognitively impaired groups on the basis of patients’ self-assessments of personality traits and connections between personality and cognitive functioning were examined via a cross-sectional study. The sample consisted of cognitively impaired patients (N = 133), aged 50 and older, who came to a memory clinic due to cognitive complaints. The test procedure encompassed a cognitive screening, the Neuropsychological Test Battery Vienna (NTBV), and self-assessment questionnaires such as the Big Five Plus One Persönlichkeitsinventar (B5PO). While patients with subjective cognitive decline (SCD) did not differ from those with non-amnestic mild cognitive impairment (naMCI) concerning the different personality traits, patients with amnestic mild cognitive impairment (aMCI) showed significantly lower scores for extraversion (p < 0.05), openness (p < 0.001), and empathy (p < 0.001) than patients with SCD as well as patients with naMCI. Thus, cognitively impaired groups mainly differ concerning personality traits depending on whether they do show memory decline or not.

Abstract
Background Quality of life is a clinical highly relevant outcome for residents with dementia. The question arises whether small scaled homelike facilities are associated with better quality of life than regular larger scale nursing homes do. Methods A sample of 145 residents living in a large scale care facility were followed over 8 months. Half of the sample (N = 77) subsequently moved to a small scaled facility. Quality of life aspects were measured with the QUALIDEM and GIP before and after relocation. Results We found a significant Group x Time interaction on measures of anxiety meaning that residents who moved to small scale units became less anxious than residents who stayed on the regular care large-scale units. No significant differences were found on other aspects of quality of life. Conclusions This study demonstrates that residents who move from a large scale facility to a small scale environment can improve an aspect of quality of life by showing a reduction in anxiety.

Abstract
Alzheimer’s disease (AD) is a major and devastating neurodegenerative disease, and the amyloid-β (Aβ) hypothesis is still the central theory for AD pathogenesis. Meanwhile, another major mental illness, depression, is one of the risk factors for AD. From a high-throughput screening (HTS), amoxapine, a typical secondary amine tricyclic antidepressant (TCA), was identified to reduce Aβ production. A follow-up investigation on antidepressants showed that most of the TCAs harbour similar activity. Previous studies have indicated that TCAs improve cognitive function in AD mouse models as well as in preliminary clinical data; however, the underlying mechanism is controversial, and the effect on Aβ is elusive. Thus, we developed a secondary screening to determine the molecular target of amoxapine, and serotonin receptor 6 (HTR6) was identified. Knockdown of HTR6 reduced the amoxapine’s effect, while the HTR6 antagonist SB258585 mimicked the activity of amoxapine. Further mechanistic study showed that amoxapine and SB258585 reduced Aβ generation through multiple HTR6-mediated targets, including β-arrestin2 and CDK5. Taken together, our study suggests that amoxapine, though no longer a first-line drug for the treatment of depression, may be beneficial for AD and further structural modification of TCAs may lead to desirable therapeutic agents to treat both AD and depression.

Subjective memory impairment in general practice : Short overview and design of a mixed methods study. Z Gerontol Geriatr 2017; 50:48-54. [PMID: 28289829 DOI: 10.1007/s00391-017-1207-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2016] [Revised: 12/04/2016] [Accepted: 02/17/2017] [Indexed: 10/20/2022]
Abstract
BACKGROUND Public awareness for dementia is rising and patients with concerns about forgetfulness are not uncommon in general practice. For the general practitioner (GP) subjectively perceived memory impairment (SMI) also offers a chance to broach the issue of cognitive function with the patient. This may support GPs' patient-centered care in terms of a broader frailty concept. OBJECTIVE What is SMI (definition, operationalization, prevalence and burden)? Which conceptions and approaches do GPs have regarding SMI? METHODS Narrative overview of recent SMI criteria and results, selective utilization of results from a systematic literature search on GP dementia care, non-systematic search regarding SMI in general practice, deduction of a study design from the overview and development according to international standards. RESULTS Studies revealed that approximately 60% of GP patients aged >74 reported a declining memory, every sixth person had concerns about this aspect and only relatively few seek medical advice. Concerns about SMI are considered a risk factor for future dementia. Specific general practice conceptions about SMI could not be identified in the literature. Using guidelines for mixed methods research, the design of an exploratory sequential mixed methods study is presented, which should reveal different attitudes of GPs towards SMI. CONCLUSION Subjective memory impairment (SMI) is a common feature and troubles a considerable proportion of patients. Neuropsychiatric research is progressing, but for the transfer of the SMI concept into routine practice, involvement of GP research is necessary. A new study aims to make a contribution to this.
