Effectiveness of Cognitive Stimulation Therapy (CST) for mild to moderate dementia: A systematic literature review and meta-analysis of randomised control trials using the original CST protocol.

AIMS: We aimed to conduct a systematic literature review and meta-analysis to evaluate the efficacy of the original 14 session Cognitive Stimulation Therapy (CST) protocol in improving cognitive function and related outcomes in people with mild to moderate dementia. METHODS: Four databases were searched, up to May 2023, for randomized controlled trials of CST using the original protocol. Pre- and post-test means and measures of dispersion for intervention and control groups were extracted for each reported outcome and used to calculate effect sizes. Effect sizes were grouped by outcome and pooled in inverse variance weighted random effects models. RESULTS: Twelve studies were identified as meeting inclusion criteria. Of these, ten were given either a 'high' or 'medium' quality rating. The pooled results indicated that CST had a significant beneficial impact on global cognition, language, working memory, depression, neuropsychiatric symptoms, communication, self-reported quality of life and severity of dementia. CONCLUSIONS: CST as delivered in adherence to the original 14-session protocol is an efficacious treatment for mild to moderate dementia with improvements in cognition, affective symptoms and quality of life demonstrated from global trials.

An Investigation of the Wishes, Needs, Opportunities and Challenges of Accessing Meaningful Activities for People Living with Mild to Moderate Dementia.

Many people are keen to be actively involved in social life and activities, but even at an early stage, dementia can have a negative impact on social participation and access to leisure activities. As part of the IDoService project, this study has investigated people's needs and wishes, barriers and facilitators to identify opportunities for improving access to meaningful activities. Individual and focus group interviews were conducted with 5 people living with mild to moderate dementia, 2 familial and 2 professional care partners, as well as 12 people working in the field of dementia and/or community activities. Thematic analysis has highlighted the benefits of participating in meaningful activities, such as empowerment and pride, social contacts, and feeling useful to others. A number of barriers to participation relating to individual and environmental factors were reported. Even where participants praised dementia-friendly activities and facilities, they advocated activities inclusive for all and mentioned that some people might be reluctant to participate in dementia-labelled activities because they may not be suitable for their needs. These results indicate the need for developing tailored opportunities for people with mild to moderate dementia and provide valuable insights for researchers, service providers, policymakers and charities wanting to improve access.

Clinical Trajectories of Neuropsychiatric Symptoms in Mild-Moderate to Advanced Dementia.

BACKGROUND: There is high prevalence of neuropsychiatric symptoms (NPS) among dementia patients. NPS are correlated with dementia progression, functional decline, early institutionalization, and death. There is scarce evidence on the progression of NPS in the latest stages of dementia. OBJECTIVE: To describe the prevalence of NPS in mild-moderate to severe dementia and to reveal the progression of each NPS over time. METHODS: We studied 317 patients (77.3% female, average age: 81.5 years) with a DSM-IV-TR diagnosis of dementia. This is a cross-sectional, and a prospective longitudinal study with 78-month follow-up. We assessed cognitive status (Mini-Mental State Examination and Severe Mini-Mental State Examination), dementia severity (Global Deterioration Scale and Clinical Dementia Rating), and psychopathological measures (Neuropsychiatric Inventory, APADEM-Nursing Home, Apathy Inventory, Cornell Scale for Depression in Dementia, and Cohen-Mansfield Agitation Inventory). RESULTS: Overall prevalence of NPS was 94.6%, being apathy the most prevalent (66.7%) and the one whose severity increased the most with progression of dementia. Agitation/aggression, irritability, and sleeping and eating disorders also increased over time. Delusions and depressive symptoms decreased in severity with disease progression. In severe dementia, female displayed more depressive symptoms and eating disorders, while male displayed more agitation/aggression and sleep disturbances. CONCLUSION: NPS in dementia follow a heterogeneous course. Apathy is the most prevalent NPS and the one that worsens most significantly over time. The course of some NPS differs between sexes. Further research is required to understand the evolution of NPS at advanced stages of dementia.

A Qualitative Exploration of the Needs of Community-Dwelling Patients Living with Moderate Dementia.

Few studies have focused on developing a better understanding of the needs of patients with moderate-stage dementia. This study aimed to explore the needs of people living with moderate dementia and receiving home-care services from a local mental hospital. The study adopted a descriptive qualitative approach with purposive sampling to recruit patients with moderate dementia and receiving home-care services. Data were collected by face-to-face interviews and content analysis was used to interpret the experiences in the dialogue data. The results showed that the needs of people living with moderate dementia receiving home-care services contained four themes: the demand for company and care, the wish to recall familiar images, the need of reaffirming life purpose and value through reflection and reminiscence, and the desire for making autonomous end-of-life decisions. In addition to daily care, people living with moderate dementia crave companionship, expect meaningful exchanges of experiences to share their life, and have demands to have a voice in going through the final stage of life. The participants tended to focus more on issues related to the connections between living and dying. The results provide caregivers and home-care service providers with some insights into offering better care for people living with moderate dementia.

Amino Acid Levels as Potential Biomarker of Elderly Patients with Dementia.

Dementia is a clinical syndrome characterized by cognitive impairment, in which there is disturbance of multiple higher cortical functions. The primary risk factor of dementia is old age, and due to significant changes in the worldwide demographic structure, the prevalence of cognitive impairment is increasing dramatically with aging populations in most countries. Alzheimer's disease is the predominant and leading cause of dementia. The aim of this study was to evaluate the modifications of amino acids that characterize the initial stages of dementia to help our understanding of the complex and multifactorial pathogenesis of neurodegenerative disorders. A total of 123 participants were divided into two groups: healthy elderly subjects and patients with mild or moderate dementia. The results of this study indicate that the serum levels of three amino acids were changed significantly in patients with dementia, in relation to the subjects without dementia. In particular, we observed differences in concentrations for serine, arginine and isoleucine (all of them were significantly increased in patients with dementia, compared with the control group). Our results suggest that the metabolisms of some amino acids seem be changed in patients with dementia. We conclude that amino acid profiling might be helpful for the better understanding of biochemical and metabolic changes related to the pathogenesis and progression of dementia. However, considering the multifactorial, heterogenous and complex nature of this disease, validation with a greater study sample in further research is required.

Protocol for a systematic review on the experience of informal caregivers for people with a moderate to advanced dementia within a domestic home setting.

BACKGROUND: The knowledge about the experience of informal caregivers who provide care to people with moderate to advanced dementia in a domestic home setting is limited. A consequence of long hours of caregiving in addition to dealing with normal challenges of daily living is their experience of a poor quality of life. Some of their experiences may be described in terms of a feeling of powerlessness to make changes during care provision. This feeling may also suggest an experience of moral distress. The aim of this systematic review is to synthesise qualitative evidence relating to these experiences. METHODS: This review adopts a narrative synthesis approach. A search will be conducted for studies written in the English language in the bibliographic databases MEDLINE Complete, CINAHL, EMBASE, PsycINFO, Web of Science and Academic Search Complete covering periods from 1984 to present. Included studies will be qualitative or mixed-methods designs. The search terms will be related to dementia and caregivers, and the process will be focused on dementia at the moderate to the advanced stages within the domestic home setting. Reference lists of included papers will also be searched for additional relevant citations. Search terms and strategies will be checked by two independent reviewers. The identification of abstracts and full texts of studies will be done by the author, while the quality and the risk of bias will also be checked by the two independent reviewers. DISCUSSION: Psychological distress is cited as an experience reported within informal caregiving. For the caregiver, it is associated with a negative impact on general health. To date, no synthesis exists on the specific experience of informal caregiving for people with moderate to advanced dementia within the domestic home setting. This review considers that variation of accounts contributes to how the informal caregivers' general experience is explored in future research. This may enable gaps in current knowledge to be highlighted within the wider context of caregiving in the domestic home setting. SYSTEMATIC REVIEW REGISTRATION: This review is registered with PROSPERO ( CRD42020183649 ).

How Volunteers Contribute to Persons with Dementia Coping in Everyday Life.

INTRODUCTION: The society needs volunteers to fulfill its duty to ensure that people with dementia have active and meaningful everyday lives. Volunteers seem to experience their work as positive and meaningful for their own part, but we know less about what motivates volunteers to start working in home-dwelling dementia care and what motivates them to continue their engagement. This study seeks to close some of the knowledge gaps that exist regarding volunteers' engagement in activities for persons with dementia. AIM: The aim of this study was to explore what motivates volunteers to start engaging in volunteer work in home-dwelling dementia care and what motivates them to continue their engagement. METHODS: The study design was qualitative, using focus group interviews. Three focus group interviews (n=16) took place between May and June 2018. The text was analyzed using content analysis. RESULTS: Findings in this study indicate that the volunteers were motivated by the feeling of doing an important job for the persons with dementia and their relatives, and that they contribute to their coping with everyday life. Other motivating factors included feeling important to someone, gaining friendship, and sharing common interests. They also believed that they do an important job for the community to fulfill society's goal that people with dementia should stay home longer. However, the volunteers were confused about their role and ask for knowledge, peer support, and clarification of roles. CONCLUSION: To maintain motivation volunteers need to know what his/her role is. A volunteer can and shall not act as a substitute for a professional, only as a supplement, and the expectations must be addressed to all stakeholders: the health care service, the volunteer, the person with dementia, and their relatives, as we believe that this will contribute to diminishing misunderstandings.

The validity, reliability and clinical utility of a performance-based executive function assessment in people with mild to moderate dementia.

Objective: Performance-based evaluation of executive function by using real-world daily living activities is an important area of study. This approach has been used extensively in evaluating patients after stroke or traumatic brain injury and patients with schizophrenia. Most important is the fact that until now, there has been no validated performance-based evaluation of executive function in people with dementia.Methods: To address that knowledge gap, this study recruited 80 patients diagnosed with dementia and 80 demographically matched healthy controls. The participants were administered tests for evaluating their performance-based executive function (Chinese Multiple Errands Test), their instrumental activities of daily living (Lawton Instrumental Activities of Daily Living Scale, Chinese Version), and their functional disability (Chinese Version of the Disability Assessment for Dementia), along with a cognitive screening test (Montreal Cognitive Assessment, Hong Kong Version) and a neuropsychological test of executive function (Trail-making Test).Results: The Chinese Multiple Errands Test demonstrated excellent inter-rater reliability, test-retest reliability and high internal consistency. Results revealed that the healthy controls out-performed the dementia patients in the performance-based executive function and cognitive screening, but not in the instrumental activities of daily living tests. Additionally, the performance efficiency scores of the older adults with dementia on the Chinese Multiple Errands Test correlated significantly with their performance results on the neuropsychological test of executive function and on the tests of functional disability and cognitive function.Conclusion: Our results indicated that the Chinese Multiple Errands Test is a reliable and valid instrument for assessing executive function in Chinese older people with dementia.

Psychosocial Interventions for Community-Dwelling People Following Diagnosis of Mild to Moderate Dementia: Findings of a Systematic Scoping Review.

National policies and evidence reviews recommend psychosocial interventions (PIs) as an essential support, particularly in the period following dementia diagnosis. However, availability and uptake of these interventions are comparatively low. One of the reasons for this is that clinicians lack information about what might be provided and the potential benefits of different interventions. This article identifies and describes PIs for community-dwelling people following diagnosis of mild to moderate dementia and presents the available evidence to inform practice decisions. A systematic scoping review was employed to map the evidence relating to PIs for this group. This identified 63 relevant studies, testing 69 interventions, which could be grouped into 6 intervention categories: 20 cognition-oriented, 11 behavior-oriented, 11 stimulation-oriented, 13 emotion-oriented, 5 social-oriented, and 9 multimodal. There were three targets for outcome measurement of these PIs: the person with dementia, the family caregiver, and the person-caregiver dyad. Over 154 outcome measures were identified in the studies, with outcomes measured across 11 main domains. The lack of a classification framework for PIs means it is difficult to create a meaningful synthesis of the breadth of relevant evidence to guide clinical practice. Possible dimensions of a classification framework are proposed to begin to address this gap.

Quality of Life for Dementia Caregiving Dyads: Effects of Incongruent Perceptions of Everyday Care and Values.

Purpose of the Study: This dyadic study investigated incongruence in care recipients' (CRs') and caregivers' (CGs') perceptions of (a) CRs' involvement in decision making and (b) how much CRs value social relations as predictors of subjective quality of life (QOL) of CRs with mild-to-moderate dementia and their primary family CGs. Design and Methods: A secondary analysis of cross-sectional, dyadic data from in-person interviews with 205 CRs with mild-to-moderate dementia and their primary family CGs Incongruence was operationalized in two ways: absolute difference and direction of difference. Paired t tests and multilevel modeling were used to analyze differences. Results: CGs reported CRs were significantly less involved in decision making and valued social relations significantly less than CRs. Greater incongruence on CRs' values significantly predicted lower QOL of CG and CR. When CGs reported that CRs valued social relationships less than the CR himself/herself reported, CGs' and CRs' QOL was significantly lower compared with QOL for dyads where there was no incongruence on CRs' values. Incongruent perceptions of CRs' involvement in decisions were not a significant predictor of QOL. Implications: This study provides evidence for the importance of assessing both CRs' and CGs' QOL, as well as incongruence in their perceptions in domains that may affect both of their QOL.

High tau levels in cerebrospinal fluid predict nursing home placement and rapid progression in Alzheimer's disease.

BACKGROUND: Increased concentrations of cerebrospinal fluid (CSF) total tau (t-tau) and phosphorylated tau, as well as decreased amyloid-ß 42 peptide, are biomarkers of Alzheimer's disease (AD) pathology, but few studies have shown an association with AD progression rate. We hypothesized that high CSF tau, as a marker of ongoing neurodegeneration, would predict a more aggressive course of AD, using time to nursing home placement (NHP) as the main outcome. METHODS: Our sample inlcuded 234 patients with mild cognitive impairment (MCI) due to AD (n = 134) or mild to moderate AD (n = 100) who underwent lumbar puncture at a memory clinic and were followed for 2-11 years (median 4.9 years). RESULTS: Individuals with CSF t-tau in the highest quartile (≥900 ng/L) had a higher ratio of NHP, both in the total cohort and in patients with MCI only (adjusted HR 2.17 [95% CI 1.24-3.80]; HR 2.37 [95% CI 1.10-5.09], respectively), than the lowest quartile. The association between high t-tau levels and future steep deterioration was confirmed in analyses with conversion to moderate dementia (HR 1.66; 95% CI 1.08-2.56), rapid decline in Mini Mental State Examination score (≥4-point drop/12 months), and dying in severe dementia as outcomes. CONCLUSIONS: To our knowledge, this is the first study to show that high CSF t-tau levels predict early NHP and conversion to moderate dementia in an AD cohort. Selecting patients with high CSF t-tau, indicating more aggressive neurodegeneration and steeper decline, for AD immunotherapy trials might increase the possibility of showing contrast between active treatment and placebo.

How Dementia Affects Personal Dignity: A Qualitative Study on the Perspective of Individuals With Mild to Moderate Dementia.

OBJECTIVE: This article examines how dementia affects personal dignity in individuals with mild to moderate dementia from their perspective. METHOD: In this qualitative cross-sectional study, in-depth interviews were carried out with 14 individuals, aged 50-94, with mild to moderate dementia who lived at home. Verbatim transcripts were analyzed making use of the principles of thematic analysis. RESULTS: Although mild to moderate dementia resulted in a diminished sense of personal dignity, in general participants still felt reasonably dignified. The decline in personal dignity was generally caused by cognitive impairments resulting in diminished autonomy and changes to the individual's former identity. However, the intensity with which the decline in personal dignity was experienced depended to a large degree on the social context of the individual, with a marked difference between the private sphere of the home and the external, social environment. The study gives recommendations how others can help to sustain personal dignity in people with mild to moderate dementia. CONCLUSION: Given the considerable impact the social environment has on the personal dignity of people with mild to moderate dementia, it is important in caregiving not to confine attention to health-related or even any individual aspects alone, but also to take interpersonal aspects into consideration.

Comparison of Verbal and Emotional Responses of Elderly People with Mild/Moderate Dementia and Those with Severe Dementia in Responses to Seal Robot, PARO.

INTRODUCTION: The differences in verbal and emotional responses to a baby seal robot, PARO, of elderly people with dementia residing at an elderly nursing care facility were analyzed. There were two groups of elderly people: one was with mild/moderate dementia (M-group) that consisted with 19 elderly residents in the general ward, and the other was with severe dementia (S-group) that consisted with 11 elderly residents in the dementia ward. METHOD: Each elderly resident in both groups interacted with either PARO or a control (stuffed lion toy: Lion) brought by a staff at each resident's private room. Their responses were recorded on video. Behavioral analysis of the initial 6 min of the interaction was conducted using a time sampling method. RESULTS: In both groups, subjects talked more frequently to PARO than to Lion, showed more positive changes in emotional expression with PARO than with Lion, and laughed more frequently with PARO than with Lion. Subjects in M-group even showed more negative emotional expressions with Lion than with PARO. Furthermore, subjects in S-group showed neutral expression more frequently with Lion than with PARO, suggesting more active interaction with PARO. For subjects in M-group, frequencies of touching and stroking, frequencies of talking to staff member, and frequencies of talking initiated by staff member were significantly higher with Lion than with PARO. CONCLUSION: The elderly people both with mild/moderate dementia and with severe dementia showed greater interest in PARO than in Lion. The results suggest that introducing PARO may increase willingness of the staff members to communicate and work with elderly people with dementia, especially those with mild/moderate dementia who express their demand of communication more than those with severe dementia.

Guidelines for adapting cognitive stimulation therapy to other cultures.

Cognitive stimulation therapy (CST) has been shown to be an useful and cost effective intervention that increases cognition and quality of life of people with mild to moderate dementia. It is increasing in popularity in the UK and worldwide, and a number of research teams have examined its effectiveness in other contexts and cultures. However, it is necessary to develop clear evidence-based guidelines for cultural modification of the intervention. This article describes a community-based developmental approach to adapt CST to different cultures, following the five phases of the formative method for adapting psychotherapy (FMAP), an approach that involves collaborating with service users as a first step to generate and support ideas for therapy adaptation. Examples based on clinical and practical experience are presented, along with suggestions for applying these changes in different cultural contexts.

[Benefits of music therapy as therapy no pharmacology and rehabilitation moderate dementia]. / Beneficios de la musicoterapia como tratamiento no farmacológico y de rehabilitación en la demencia moderada.

An in-depth review is presented the possible benefits of music therapy in relation to the cognitive and/or behavioural level of elderly patients with dementia. We have carried out a systematic review of randomized controlled trials, case-control and pilot studies published from January 2000 to January 2012 using the Cochrane Database of Systematic Reviews, MEDLINE, Dialnet and CSIC. We focused on comparison of music therapy as non-pharmacological therapy, in patients over 65 years of age with moderate dementia, with regular therapeutic and occupational treatment. Ten articles were selected based on the inclusion criteria. The analysis of the results suggest that music Therapy influences the elderly people with dementia in a positive way by improving levels of behavioural and cognitive functioning and social participation.

Variables asociadas con la depresión y la sobrecarga que experimentan los cuidadores principales de los ancianos con Alzheimer / Variable associate with depression and burden level of caregivers of the elderly people with Alzheimer

La enfermedad de Alzheimer no solo afecta a la persona que la padece, sino que también repercute de manera muy importante en la familia. El cuidado de estos pacientes eleva la morbilidad psicológica y el estrés de los cuidadores principales. El propósito de este estudio fue identificar las variables asociadas con la depresión y la sobrecarga que experimentan los cuidadores principales de estos pacientes. Se realizó un estudio descriptivo que incluyó a 100 cuidadores de adultos mayores con demencia leve y moderada, que asistieron a la Consulta de Trastornos Cognitivos del Hospital Carlos J Finlay. Entre las características socio-demográficas predominaron los cuidadores del sexo femenino, el grupo de edad entre 40 y 49 años y los cuidadores con grado de consanguinidad con el anciano. Además, predominó entre los cuidadores el estado civil casado y la mayoría de los cuidadores tienen vínculo laboral. La sobrecarga y la depresión experimentada por los cuidadores principales fueron elevadas. Las variables asociadas a la depresión y la sobrecarga fueron los cuidadores principales que no reciben apoyo y sus pacientes presentaban trastornos en los hábitos alimentarios(AU)

Alzheimer's disease not only affects older people suffering from it but also has a significant effect on his/her family. The care of this patient increases the psychological morbidity and stress in the main caregivers. The purpose of this study was to identify associate variables to depression and burden in the caregivers. We realized a descriptive study that included 100 caregivers of elderly people with mild and moderate dementia, from cognitive consult in Carlos J Finlay Hospital. Among socio-demographic characteristics was a predominance of women, most were middle age (40 _ 49 year) and most of them were married. Nearly one half of the caregivers worked outside the home, and the caregivers had relationship with the patient with dementia. The depression and burden were elevated in the caregivers. Moreover, the variables associated with depression and burden were the caregivers not received help and the patients with alimentary habits as behavior and psychological symptoms(AU)

Características sociodemográficas y nivel de sobrecarga de cuidadores de ancianos con Enfermedad de Alzheimer / Sociodemographic characteristics and level of overburden in caregivers of the elderly with Alzheimer´s disease

La enfermedad de Alzheimer no solo afecta a la persona que la padece, sino que también repercute de manera muy importante en la familia. Son los familiares cuidadores los que, de forma mayoritaria, se hacen cargo de la atención de estos enfermos con una dedicación de 24 horas. El propósito de este estudio fue describir las características socio-demográficas y el nivel de sobrecarga de los cuidadores informales de adultos mayores con demencia leve y moderada. Se realizó un estudio descriptivo que incluyó a 75 cuidadores de adultos mayores con demencia leve y moderada, que asistieron a la Consulta de Trastornos Cognitivos del Hospital «Carlos J. Finlay¼. Entre las características socio-demográficas predominaron los cuidadores del sexo femenino, el grupo de edad entre 40 y 49 años y los cuidadores con grado de consanguinidad con el anciano. Además, predominó entre los cuidadores el estado civil casado y la mayoría de los cuidadores tienen vínculo laboral. Además, los cuidadores de los adultos mayores demencia moderado evidenciaron mayor nivel de sobrecarga que los cuidadores de los adultos mayores con demencia leve o en estadios iniciales de la enfermedad(AU)

Alzheimer´s disease not only affects the sufferer but also has a significant impact on the family. The relatives of the sick person are the ones that mostly act as caregivers 24 hours a day. The objective of this study was to describe the sociodemographic characteristics and the level of overburden of the informal caregivers of older adults with mild and moderate dementia. A descriptive study of 75 caregivers of older adults affected by mild and moderate dementia, who had gone to the Cognitive Disorders Department in "Carlos J. Finlay" hospital, was conducted. Some of the sociodemographic characteristics found in this study were: females, the 40-49 years age group, and kinship predominated in the studied caregivers. Besides, they were mostly married and workers; and the caregivers of older adults with moderate dementia evinced higher level of overburden than those of the elderly with mild dementia or at the initial phases of Alzheimer´s disease(AU)
