RESUMO

BACKGROUND: Getting a diagnosis of dementia does not equate to equitable access to care. People with dementia and unpaid carers face many barriers to care, which can vary within, and across, different countries and cultures. With little evidence across different countries, the aim of this scoping exercise was to identify the different and similar types of inequalities in dementia across Europe, and provide recommendations for addressing these. METHODS: We conducted a brief online survey with INTERDEM and INTERDEM Academy members across Europe, and with members of Alzheimer Europe's European Working Group of People with Dementia and Carers in February and March 2023. Members were asked about whether inequalities in dementia care existed within their country; if yes, to highlight three key inequalities. Responses on barriers were coded into groups, and frequencies of inequalities were calculated. Highlighted inequalities were discussed and prioritised at face-to-face and virtual consensus meetings in England, Ireland, Italy, and Poland, involving people with dementia, unpaid carers, health and social care providers, and non-profit organisations. RESULTS: Forty-nine academics, PhD students, people with dementia and unpaid carers from 10 countries (Belgium, Denmark, Germany, Greece, Ireland, Italy, Poland, Malta, Netherlands, UK) completed the survey. The most frequently identified inequalities focused on unawareness and lack of information, higher level system issues (i.e. lack of communication among care professionals), lack of service suitability, and stigma. Other barriers included workforce training and knowledge, financial costs, culture and language, lack of single-point-of-contact person, age, and living location/postcode lottery. There was general consensus among people living dementia and care providers of unawareness as a key barrier in different European countries, with varied priorities in Ireland depending on geographical location. CONCLUSIONS: These findings provide a first insight on dementia inequalities across Europe, generate cross-country learnings on how to address these inequalities in dementia, and can underpin further solution-focused research that informs policy and key decision makers to implement changes.

RESUMO

This study analyzes the clinical characteristics of patients diagnosed with White Piedra through a systematic review of cases in the literature. A sample of 131 subjects was considered, of which 91.6% were female and most were 18 years of age or younger. Most studies were conducted in Brazil, followed by India, and Mexico. The most common etiologic agent found was Trichosporon spp (34.3%). Most affected patients were asymptomatic (94.6%) and predisposing factors included long hair, use of a hair band or hair accessories, and wet hair. The most common clinical feature was the presence of nodules. The evaluation of treatment effectiveness was hindered by the scarcity of follow-up information in the majority of the studies. It is concluded that White Piedra infection is more common in young women and is associated with hair-related factors.

RESUMO

OBJECTIVES: To explore the prevalence and clinical significance of low complement levels in patients with catastrophic antiphospholipid syndrome (CAPS). METHODS: We reviewed data from the "CAPS Registry" on C3 and/or C4 complement plasma protein levels during acute CAPS episodes. Patients were classified into those with low and normal complement levels. Data on clinical presentation, with special focus on thrombotic microangiopathy (TMA) features, diagnosis of systemic lupus erythematosus (SLE), and antiphospholipid antibody (aPL) profile were reviewed. The chi-square exact test was performed to evaluate differences between categorical data. RESULTS: The "CAPS Registry" includes 566 patients with a total of 578 episodes of CAPS. Data on complement plasma protein levels was available in 73 episodes from the same number of patients. Low levels of C3 and/or C4 complement plasma proteins were detected in 42 (58%) CAPS episodes. Low complement levels were more common in SLE patients (55% SLE vs. 19% No SLE; p<0.001). The frequencies of clinical TMA (72% vs. 80%; p=0.4) or TMA syndrome (86% vs. 84%, p=0.9), frequency of triple aPL triple positivity (67% vs 33%; p=0.3), or the mortality (35% vs. 31%; p=0.7) were similar between low and normal complement groups. CONCLUSION: In our study, low levels of C3 and C4 plasma proteins are detected in 58% episodes of CAPS, which were not associated with clinical presentation including TMA features, aPL triple positivity, or mortality.

RESUMO

AIMS: We aim to identify existing empowerment interventions for people living with dementia and to explore which used interventions and projects are considered empowering and why. DESIGN: This was an online survey. METHODS: We conducted an online survey between May 2018 and July 2018 amongst professionals interested in dementia care in Europe. Interventions were clustered within the ecological model for health promotion. Reasons from respondents as to why they considered interventions to be empowering were analysed and structured according to a recently developed conceptual framework of empowerment for people living with dementia. RESULTS: Seventy-three respondents from 23 countries together mentioned 98 interventions or projects, of which 90 were unique. Interventions focused on the (inter)personal (n = 54), organizational (n = 15), communal (n = 6) and societal (n = 15) levels. A broad range of interventions were considered empowering, but no interventions were specifically developed for, nor aimed at, empowerment. Reasons as to why respondents considered these interventions as empowering fitted the framework's domains. CONCLUSION: This European survey provides insights into interventions considered empowering for people living with dementia. An important step that needs to be taken is to develop and test interventions that specifically aim to promote empowerment for people living with dementia. IMPACT: Empowerment may encourage people with dementia to live the life they choose, and focus on what is possible, instead of what is no longer possible. Many interventions are considered as empowering for people living with dementia, however no interventions could be identified that were specifically developed for or aimed at empowerment. This study shows that for promoting empowerment, it is necessary to develop and test interventions that specifically aim for empowerment, do this in collaboration with relevant stakeholders, and in this way support people living with dementia to live according to their competencies, talents and wishes.

RESUMO

This study aimed to evaluate the effect of high-intensity ultrasound as pre-treatment in the development of fermented whey and oat beverages. Oat malt was produced, incorporated into a whey formulation (35, 50 and 65% v/v of whey) and ultrasonicated (at 40 kHz and 11 W/cm2) for 0, 3 or 10 min, prior to fermentation with L. casei 431. The treatments were identified as 35/65/0, 50/50/0, 65/35/0, 35/65/3, 50/50/3, 65/35/3, 35/65/10, 50/50/10 and 65/35/10, referring to the whey percentage, oat percentage, and the ultrasound time (min), respectively. The beverages 50/50/0 and 50/50/3 registered the highest (P < 0.05) growth with 1.96 and 2.00 log CFU ml, respectively. In general, the final average population of L. casei 431 was 7 to 8.86 log CFU/ml, being this adequate for a probiotic beverage. The highest antioxidant activity was found in the 35/65/3, 35/65/10, 50/50/3 and 50/50/10 beverages without difference (P < 0.05) among them. There was no effect of gender on the acceptance of the probiotic beverages. The best accepted beverage by women was 50/50/3 and both genders disliked the beverage 35/65/10. There was no relationship between the acceptance of the beverages and the consumers' habit by fermented milk beverages. No difference in the preference between the 50/50/0 and the 50/50/3 beverage was found. It is concluded that the probiotic beverage containing 50% whey and 50% oat and ultrasonicated for 3 min generated the highest levels of L. casei 431 growth, high antioxidant activity and good consumer acceptance and preference.

RESUMO

BACKGROUND: Patient engagement is becoming more customary in medicine development. However, embedding it in organizational decision-making remains challenging, partly due to lack of agreement on its value and the means to evaluate it. The objective of this project was to develop a monitoring and evaluation framework, with metrics, to demonstrate impact and enhance learning. METHODS: A consortium of five patient groups, 15 biopharmaceutical companies and two academic groups iteratively created a framework in a multi-phase participatory process, including analysis of its application in 24 cases. RESULTS: The framework includes six components, with 87 metrics and 15 context factors distributed among (sub)components: (a) Input: expectations, preparations, resources, representativeness of stakeholders; (b) Activities/process: structure, management, interactions, satisfaction; (c) Learnings and changes; (d) Impacts: research relevance, study ethics and inclusiveness, study quality and efficiency, quality of evidence and uptake of products, empowerment, reputation and trust, embedding of patient engagement; (e) Context: policy, institutional, community, decision-making contextual factors. Case study findings show a wide variation in use of metrics. There is no 'one size fits all' set of metrics appropriate for every initiative or organization. Presented sample sets of metrics can be tailored to individual situations. CONCLUSION: Introducing change into any process is best done when the value of that change is clear. This framework allows participants to select what metrics they value and assess to what extent patient engagement has contributed. PATIENT CONTRIBUTION: Five patient groups were involved in all phases of the study (design, conduct, interpretation of data) and in writing the manuscript.

RESUMO

BACKGROUND: The holistic evolution of patient engagement in medicines development requires a more detailed understanding of the needs of all involved stakeholders, and one that better accounts for the specific needs of some potentially vulnerable patient populations and key stages in medicines development. OBJECTIVE: The purpose of this convergent mixed-methods study was to better understand the needs of different stakeholders concerning patient engagement at three key stages in medicines development: research priority setting, clinical trial design and early dialogues with Health Technology Assessment bodies and regulators. DESIGN: This study brought together findings from three sources: i) an online questionnaire, ii) face-to-face consultations with two potentially vulnerable patient populations, a workshop with Health Technology Assessment bodies, and iii) three-step modified Delphi methodology. RESULTS: Overall stakeholders still need additional varied support mechanisms to undertake, sustain or measure value of patient engagement. Health Technology Assessment bodies need better rationale for patient engagement in early dialogue and tools to support its implementation. Improved awareness and understanding of the need and value that involving patients, who are often considered as potentially vulnerable, can bring is needed, as is better accommodation of their specific needs. Similarly, weighted Delphi categories were as follows: aims and objectives, and sustainability. Several additional themes were common across the three key stages in medicines development. CONCLUSION: This broad-reaching study provides the blocks needed to build a framework for patient engagement in medicines development. PATIENT OR PUBLIC CONTRIBUTION: Patients were involved in review and interpretation of data.

RESUMO

AIMS: The aim of this study was to explore the opinions of people with dementia, about the language used to describe changes in behaviour associated with dementia. DESIGN: This study adopted a human rights approach in a mixed methods convergent parallel synthesis design. METHODS: Online and paper-based questionnaire data were collected between November 2019 and March 2020. A combination of convenience and purposive sampling was used to invite people with dementia to participate. RESULTS: In total, 54 people completed the survey. There was no clear consensus on a preferred term, but 28.3% preferred the term 'unmet needs' for describing changes in behaviour associated with dementia. Qualitative data revealed important nuances and challenges for researchers and practitioners in relation to terminology for this paradigm. Participants felt that the language we use to talk about changes in behaviour could influence how people with dementia are viewed and treated and how people feel about themselves. CONCLUSION: The majority of participants were familiar with a range of terminology. There was no universal agreement on terminology, but there was an overall preference for terms that reflect the unmet needs likely to underlie perceived changes in behaviour. IMPACT: People with dementia raised concerns about the language used to describe changes in behaviour that can occur in dementia. There is scope for improvements in the language used for this paradigm in both research and practice. Following a diagnosis of dementia, clinicians need to take the time to explore an individual's preferences and understandings. They can then share their own understanding about the potential for changed behaviour and if relevant, how any negative impact of this may be minimized.

RESUMO

BACKGROUND: People with dementia are often marginalized and excluded from influence, also in relation to dementia research. There is, however, a growing requirement for inclusion through Patient and Public Involvement (PPI), but there is still limited knowledge on how researchers can fully benefit from the involvement of people with dementia in the development and testing of psychosocial interventions. This paper describes the results of a pan-European consultation with people with dementia, synthesizing their views on outcomes of psychosocial interventions. OBJECTIVE: To involve people with dementia in establishing what are meaningful outcomes when participating in psychosocial interventions. SETTING AND PARTICIPANTS: Consultations took place at four divergent sites across Europe, involving twenty-five people with dementia from nine European countries. METHODS: The methods used for the consultation were developed through an iterative process involving people with dementia. Data from the consultation were analysed from a thematic analysis approach. RESULTS: The results suggested that people with dementia wish to participate in interventions that enhance their well-being, confidence, health, social participation and human rights. This highlights a need for improvements in psychosocial research to capture these outcomes. DISCUSSION AND CONCLUSIONS: Involving people with dementia in discussions of psychosocial interventions has enhanced our understanding about meaningful outcome measures in research and methods of data collection. This study suggests that new outcome measures in psychosocial research are needed where concepts of positive psychology and social health can guide innovation and outcome measurement.

RESUMO

This paper reflects Alzheimer Europe's position on PPI (patient and public involvement) in the context of dementia research and highlights some of the challenges and potential risks and benefits associated with such meaningful involvement. The paper was drafted by Alzheimer Europe in collaboration with members of INTERDEM and the European Working Group of People with Dementia. It has been formally adopted by the Board of Alzheimer Europe and endorsed by the Board of INTERDEM and by the JPND working group 'Dementia Outcome Measures - Charting New Territory'. Alzheimer Europe is keen to promote the involvement of people with dementia in research, not only as participants but also in the context of PPI, by generating ideas for research, advising researchers, being involved in consultations and being directly involved in research activities. This position paper is in keeping with this objective. Topics covered include, amongst others, planning involvement, establishing roles and responsibilities, training and support, managing information and input from PPI, recognising the contribution of people with dementia involved in research in this way, promoting and protecting the rights and well-being of people with dementia, training and support, and promoting an inclusive approach and the necessary infrastructure for PPI in dementia research.

RESUMO

BACKGROUND: There is limited literature around peer research in dementia. This study aims to identify the benefits, the risks and the practical challenges and to develop a model of good practice in peer research with people with dementia. METHODS: We searched on PsycInfo, PubMed and Google Scholar for empirical investigations or discussion papers on peer research. Given the limited literature in the field of dementia, we included studies with groups who share similar demographics (older people), experience of stigma (mental health service users) and exclusion from research (people with learning disabilities). We applied no restrictions on language and publication date. ANALYSIS: We identified three themes: the potential benefits, the potential risks and the practical challenges of peer research. We developed a model of good practice. The European Working Group of People with Dementia reviewed our paper and added to our findings. RESULTS: We included seven papers. Potential benefits of peer research included enriched data and empowering people with dementia. Potential risks included power differentials between researchers and issues of representativeness. The practical issues for good practice included the training of peer researchers, defining involvement and roles, working with cognitive impairment and considering resource implications. The European Working Group of People with Dementia emphasised the importance of equality issues. CONCLUSION: Involving people with dementia in peer research can generate several benefits, including empowerment and opportunities for inclusion for the peer researchers and the research participants living with dementia, challenging academics' traditional views on research processes and gathering enhanced research data. There remains a need for further research on the impact of peer research in dementia studies. Copyright © 2016 John Wiley & Sons, Ltd.

RESUMO

The analysis and understanding of brain characteristics often require considering region-level information rather than voxel-sampled data. Subject-specific parcellations have been put forward in recent years, as they can adapt to individual brain organization and thus offer more accurate individual summaries than standard atlases. However, the price to pay for adaptability is the lack of group-level consistency of the data representation. Here, we investigate whether the good representations brought by individualized models are merely an effect of circular analysis, in which individual brain features are better represented by subject-specific summaries, or whether this carries over to new individuals, i.e., whether one can actually adapt an existing parcellation to new individuals and still obtain good summaries in these individuals. For this, we adapt a dictionary-learning method to produce brain parcellations. We use it on a deep-phenotyping dataset to assess quantitatively the patterns of activity obtained under naturalistic and controlled-task-based settings. We show that the benefits of individual parcellations are substantial, but that they vary a lot across brain systems.

RESUMO

The Individual Brain Charting (IBC) is a multi-task functional Magnetic Resonance Imaging dataset acquired at high spatial-resolution and dedicated to the cognitive mapping of the human brain. It consists in the deep phenotyping of twelve individuals, covering a broad range of psychological domains suitable for functional-atlasing applications. Here, we present the inclusion of task data from both naturalistic stimuli and trial-based designs, to uncover structures of brain activation. We rely on the Fast Shared Response Model (FastSRM) to provide a data-driven solution for modelling naturalistic stimuli, typically containing many features. We show that data from left-out runs can be reconstructed using FastSRM, enabling the extraction of networks from the visual, auditory and language systems. We also present the topographic organization of the visual system through retinotopy. In total, six new tasks were added to IBC, wherein four trial-based retinotopic tasks contributed with a mapping of the visual field to the cortex. IBC is open access: source plus derivatives imaging data and meta-data are available in public repositories.

RESUMO

OBJECTIVES: To describe the pulmonary involvement in patients with catastrophic antiphospholipid syndrome (CAPS), focusing on its relationship with extrapulmonary involvement, laboratory, radiological, and pathological findings. METHODS: This retrospective cross-sectional study includes all patients grouped in the "CAPS Registry". All cases were reviewed, and those with pulmonary thromboembolism (PE) and/or diffuse alveolar hemorrhage (DAH) were selected. Data on pulmonary and extrapulmonary clinical presentation, radiologic patterns, laboratory findings, associated autoimmune diseases, treatments, and outcomes were analyzed. Frequency distribution and measures of central tendency were used to describe the cohort. Comparison between groups regarding qualitative variables was undertaken by chi-square or Fisher exact test, while T-test for independent variables was used to compare groups regarding continuous variables. IBM-SPSS v.22 was used for data analysis. RESULTS: PE was reported in 129 (48.6 %) episodes, DAH in 75 (28.3 %) episodes, and overlap (DAH plus PE) in 7 (2.6 %) episodes. Bronchoalveolar lavage (BAL) was performed in 35 (4.9 %) CAPS episodes, and lung pathology samples were obtained in 84 (10.5 %) episodes (including autopsies). A significant relationship was observed between DAH and laboratory features of thrombotic microangiopathy (TMA). A meaningful relationship was also found between triple antiphospholipid antibody positivity and pathological TMA (26.5 %) as well as hypocomplementemia and DAH (24 %). CONCLUSIONS: Pulmonary involvement may include both TMA and non-thrombotic inflammation, which can be differentiated into three patterns: PE, DAH with systemic TMA with hypocomplementemia or DAH without systemic TMA with/without hypocomplementemia.

RESUMO

Videogames are emerging as a promising experimental paradigm in neuroimaging. Acquiring gameplay in a scanner remains challenging due to the lack of a scanner-compatible videogame controller that provides a similar experience to standard, commercial devices. In this paper, we introduce a videogame controller designed for use in the functional magnetic resonance imaging as well as magnetoencephalography. The controller is made exclusively of 3D-printed and commercially available parts. We evaluated the quality of our controller by comparing it to a non-MRI compatible controller that was kept outside the scanner. The comparison of response latencies showed reliable button press accuracies of adequate precision. Comparison of the subjects' motion during fMRI recordings of various tasks showed that the use of our controller did not increase the amount of motion produced compared to a regular MR compatible button press box. Motion levels during an ecological videogame task were of moderate amplitude. In addition, we found that the controller only had marginal effect on temporal SNR in fMRI, as well as on covariance between sensors in MEG, as expected due to the use of non-magnetic building materials. Finally, the reproducibility of the controller was demonstrated by having team members who were not involved in the design build a reproduction using only the documentation. This new videogame controller opens new avenues for ecological tasks in fMRI, including challenging videogames and more generally tasks with complex responses. The detailed controller documentation and build instructions are released under an Open Source Hardware license to increase accessibility, and reproducibility and enable the neuroimaging research community to improve or modify the controller for future experiments.

RESUMO

Interleukin-17 (IL-17) and tumor necrosis factor (TNF) regulate tissue remodeling through matrix metalloproteinases (MMPs). It is not yet clear whether these cytokines have a functional hierarchy in psoriasis. Serum levels of TNF (1,403 versus 1,058 pg/mL), IL-17 (1,528 versus 820 pg/mL), MMP-1 (1,999 versus 1,039 pg/mL), and MMP-9 (1,950 versus 1,561 pg/mL) were higher in psoriasis subjects (n = 60) than in control subjects (n = 60). Tissue inhibitor of MMPs (TIMP-1; 1,374 versus 1,218 pg/mL) was lower in psoriasis subjects. Serum IL-17 was correlated with MMP-2 (rs = 0.40) and TIMP-1 (rs = -0.26) levels. Unstimulated production of MMP-1, MMP-2, and MMP-9 by monocytes was higher in psoriasis subjects, whereas TIMP-1 production was lower. TNF stimulation increased all MMPs, whereas TIMP-1 production was unchanged. IL-17 stimulation increased all MMPs, whereas TIMP-1 production was decreased in psoriasis subjects. MMP-9 production was higher in monocytes stimulated with IL-17 compared with TNF. TIMP-1 production was decreased more by IL-17 than by TNF, but only in psoriasis cells. MMP-1/TIMP-1, MMP-2/TIMP-1, and MMP-9/TIMP-1 ratios were higher after IL-17 stimulation (compared with TNF stimulation) in psoriasis subjects; this occurred in controls only for the MMP-2/TIMP-1 ratio. IL-17 has a greater ability than TNF to dysregulate the MMPs/TIMP-1 balance, supporting IL-17 blockade as first-line treatment in cutaneous psoriasis.

RESUMO

Alzheimer's disease (AD) and other neurodegenerative diseases such as Parkinson's disease (PD) and Huntington's disease (HD) are associated with progressive cognitive, motor, affective and consequently functional decline considerably affecting Activities of Daily Living (ADL) and quality of life. Standard assessments, such as questionnaires and interviews, cognitive testing, and mobility assessments, lack sensitivity, especially in early stages of neurodegenerative diseases and in the disease progression, and have therefore a limited utility as outcome measurements in clinical trials. Major advances in the last decade in digital technologies have opened a window of opportunity to introduce digital endpoints into clinical trials that can reform the assessment and tracking of neurodegenerative symptoms. The Innovative Health Initiative (IMI)-funded projects RADAR-AD (Remote assessment of disease and relapse-Alzheimer's disease), IDEA-FAST (Identifying digital endpoints to assess fatigue, sleep and ADL in neurodegenerative disorders and immune-mediated inflammatory diseases) and Mobilise-D (Connecting digital mobility assessment to clinical outcomes for regulatory and clinical endorsement) aim to identify digital endpoints relevant for neurodegenerative diseases that provide reliable, objective, and sensitive evaluation of disability and health-related quality of life. In this article, we will draw from the findings and experiences of the different IMI projects in discussing (1) the value of remote technologies to assess neurodegenerative diseases; (2) feasibility, acceptability and usability of digital assessments; (3) challenges related to the use of digital tools; (4) public involvement and the implementation of patient advisory boards; (5) regulatory learnings; and (6) the significance of inter-project exchange and data- and algorithm-sharing.

RESUMO

More than 10 million Europeans show signs of mild cognitive impairment (MCI), a transitional stage between normal brain aging and dementia stage memory disorder. The path MCI takes can be divergent; while some maintain stability or even revert to cognitive norms, alarmingly, up to half of the cases progress to dementia within 5 years. Current diagnostic practice lacks the necessary screening tools to identify those at risk of progression. The European patient experience often involves a long journey from the initial signs of MCI to the eventual diagnosis of dementia. The trajectory is far from ideal. Here, we introduce the AI-Mind project, a pioneering initiative with an innovative approach to early risk assessment through the implementation of advanced artificial intelligence (AI) on multimodal data. The cutting-edge AI-based tools developed in the project aim not only to accelerate the diagnostic process but also to deliver highly accurate predictions regarding an individual's risk of developing dementia when prevention and intervention may still be possible. AI-Mind is a European Research and Innovation Action (RIA H2020-SC1-BHC-06-2020, No. 964220) financed between 2021 and 2026. First, the AI-Mind Connector identifies dysfunctional brain networks based on high-density magneto- and electroencephalography (M/EEG) recordings. Second, the AI-Mind Predictor predicts dementia risk using data from the Connector, enriched with computerized cognitive tests, genetic and protein biomarkers, as well as sociodemographic and clinical variables. AI-Mind is integrated within a network of major European initiatives, including The Virtual Brain, The Virtual Epileptic Patient, and EBRAINS AISBL service for sensitive data, HealthDataCloud, where big patient data are generated for advancing digital and virtual twin technology development. AI-Mind's innovation lies not only in its early prediction of dementia risk, but it also enables a virtual laboratory scenario for hypothesis-driven personalized intervention research. This article introduces the background of the AI-Mind project and its clinical study protocol, setting the stage for future scientific contributions.

RESUMO

The Public Involvement (PI) of people with dementia is slowly but progressively moving from a "nice to have" to a "must have" element of good-quality dementia research. Research funders and ethics committees increasingly ask for evidence of the planning of such involvement. The actual conduct and outcome of PI are, however, unfortunately typically under or inadequately reported. In this article, we provide an overview of what PI is and why it is important to dementia research and Alzheimer Europe's approach to PI. We draw on our recent experience of compiling a set of examples of PI in different European projects in publicly available sources. This highlighted the difficulty of finding information about PI activities and the almost total lack of details of such activities in formal reports, official records, and/or public project websites. In this article, we emphasize gaps and call for more stringent conditions for the inclusion and reporting of PI work in the context of the approval and funding of dementia research projects. We call for the establishment of obligatory reporting on the nature, specific challenges, and impact of PI in dementia research in formal reports (e.g., to funders), in public project websites, and in peer-reviewed articles. Such reporting should cover several key factors such as who was involved, how they were involved, and what impact PI had on the research process.

RESUMO

OBJECTIVE: To ascertain if similarities or differences exist in perceptions of quality of life (QoL) amongst nursing home (NH) residents with different levels of cognitive impairment (CI). METHOD: Face-to-face interviews using a simple 15-item semi-structured interview schedule with 61 older people with a CI (13 mild, 20 moderate and 28 severe) living in three Dublin area based NHs. RESULTS: Four key themes of QoL with accompanying sub-themes were identified: (1) social contact, (2) attachment, (3) pleasurable activities and (4) affect. Whilst some similarities existed between the three groups, results showed emerging differences, particularly between those with a mild and severe CI. In particular, the narratives of those with a severe CI reflected an absence of social contact, a quest for human contact and a lack of awareness of structured pleasurable activities. A large majority also reported feelings of loneliness, isolation and a search for home. CONCLUSIONS: Findings support the increasing evidence that people with a CI and even those with a probable advanced dementia can often still communicate their views and preferences about what is important to them. Whilst apathy, depression and anxiety are common features of advanced dementia, the social inclusion of these people in the day-to-day ethos of NH life needs a lot more careful consideration. More research is also needed to better understand the chronic and unique needs of this very vulnerable group of people.
