Psychological treatments for depression and anxiety in dementia and mild cognitive impairment: Systematic review and meta-analysis
Anxiety and depression are common in people with dementia and mild cognitive impairment (MCI), but there is uncertainty about the effectiveness of both pharmacological and psychological therapies. To evaluate the evidence of effectiveness of psychological treatments in treating depression and anxiety in people with dementia and MCI. We carried out a systematic review and meta-analysis of randomised controlled trials (RCTs) of psychological treatment versus usual care in people with dementia and MCI. Primary outcomes were symptoms of anxiety and depression. Secondary outcomes were quality of life, ability to perform daily activities, neuropsychiatric symptoms, cognition and caregivers' self-rated depressive symptoms. We included six RCTs, involving 439 participants with dementia, which used cognitive-behavioural therapy, interpersonal therapy, counselling or multimodal interventions including a specific psychological therapy. We found beneficial effects for both depression and anxiety. Overall, the quality of the evidence was moderate for depression and low for anxiety, due to the methodological limitations of the studies we identified and the limited number of trials. The evidence from six RCTs suggests that psychological treatments are effective in reducing symptoms of depression and anxiety for people with dementia. There is a need for high-quality, multicentre trials including standardised, well-defined interventions.
Impact of person-centred care training and person-centred activities on quality of life, agitation, and antipsychotic use in people with dementia living in nursing homes: A cluster-randomised controlled trial
Agitation is a common, challenging symptom affecting large numbers of people with dementia and impacting on quality of life (QoL). There is an urgent need for evidence-based, cost-effective psychosocial interventions to improve these outcomes, particularly in the absence of safe, effective pharmacological therapies. This study aimed to evaluate the efficacy of a person-centred care and psychosocial intervention incorporating an antipsychotic review, WHELD, on QoL, agitation, and antipsychotic use in people with dementia living in nursing homes, and to determine its cost. This was a randomised controlled cluster trial conducted between 1 January 2013 and 30 September 2015 that compared the WHELD intervention with treatment as usual (TAU) in people with dementia living in 69 UK nursing homes, using an intention to treat analysis. All nursing homes allocated to the intervention received staff training in person-centred care and social interaction and education regarding antipsychotic medications (antipsychotic review), followed by ongoing delivery through a care staff champion model. The primary outcome measure was QoL (DEMQOL-Proxy). Secondary outcomes were agitation (Cohen-Mansfield Agitation Inventory [CMAI]), neuropsychiatric symptoms (Neuropsychiatric Inventory-Nursing Home Version [NPI-NH]), antipsychotic use, global deterioration (Clinical Dementia Rating), mood (Cornell Scale for Depression in Dementia), unmet needs (Camberwell Assessment of Need for the Elderly), mortality, quality of interactions (Quality of Interactions Scale [QUIS]), pain (Abbey Pain Scale), and cost. Costs were calculated using cost function figures compared with usual costs. In all, 847 people were randomised to WHELD or TAU, of whom 553 completed the 9-month randomised controlled trial. The intervention conferred a statistically significant improvement in QoL (DEMQOL-Proxy Z score 2.82, p = 0.0042; mean difference 2.54, SEM 0.88; 95% CI 0.81, 4.28; Cohen's D effect size 0.24). There were also statistically significant benefits in agitation (CMAI Z score 2.68, p = 0.0076; mean difference 4.27, SEM 1.59; 95% CI -7.39, -1.15; Cohen's D 0.23) and overall neuropsychiatric symptoms (NPI-NH Z score 3.52, p < 0.001; mean difference 4.55, SEM 1.28; 95% CI -7.07,-2.02; Cohen's D 0.30). Benefits were greatest in people with moderately severe dementia. There was a statistically significant benefit in positive care interactions as measured by QUIS (19.7% increase, SEM 8.94; 95% CI 2.12, 37.16, p = 0.03; Cohen's D 0.55). There were no statistically significant differences between WHELD and TAU for the other outcomes. A sensitivity analysis using a pre-specified imputation model confirmed statistically significant benefits in DEMQOL-Proxy, CMAI, and NPI-NH outcomes with the WHELD intervention. Antipsychotic drug use was at a low stable level in both treatment groups, and the intervention did not reduce use. The WHELD intervention reduced cost compared to TAU, and the benefits achieved were therefore associated with a cost saving. The main limitation was that antipsychotic review was based on augmenting processes within care homes to trigger medical review and did not in this study involve proactive primary care education. An additional limitation was the inherent challenge of assessing QoL in this patient group. These findings suggest that the WHELD intervention confers benefits in terms of QoL, agitation, and neuropsychiatric symptoms, albeit with relatively small effect sizes, as well as cost saving in a model that can readily be implemented in nursing homes. Future work should consider how to facilitate sustainability of the intervention in this setting. ISRCTN Registry ISRCTN62237498.
Cognitive leisure activities and future risk of cognitive impairment and dementia: systematic review and meta-analysis
ABSTRACTBackgroundAs life expectancies continue to rise, modifiable lifestyle factors that may prevent cognitive decline and dementia in later life become increasingly important in order to maintain quality of life in old age. MethodsFive meta-analyses were conducted on data from papers identified in a systematic review. Studies were grouped according to outcomes (dementia, cognitive impairment including amnestic Mild Cognitive Impairment (aMCI), Mild Cognitive Impairment (MCI), and cognitive decline) and output (risk (RR), odds (OR), or hazard ratios (HR)). ResultsNineteen studies met our inclusion criteria and quality assessments. Four of five meta-analyses showed significant associations between participation in cognitive leisure activities and reduced risk of cognitive impairment (OR = 0.69, 95% CI: 0.56–0.85) and dementia (HR = 0.58, 95% CI: 0.46–0.74; RR = 0.61, 95% CI: 0.42–0.90; OR = 0.78, 95% CI: 0.67–0.90). However, one pooled analysis of cognitive impairment studies did not reach significance (HR = 0.85, 95% CI: 0.71–1.02). Mentally stimulating leisure activities were significantly associated with later life cognition (β = 0.11, p = 0.05), better memory (β = 0.20, 95% CI: 0.11–0.29), speed of processing (β = 0.37, 95% CI: 0.29–0.45), and executive functioning (β = 0.23, 95% CI: 0.15–0.29), and less decline in overall cognition (β = −0.23, p < 0.01), language (β = −0.11, p < 0.05), and executive functioning (β = −0.13, p < 0.05). Activities were also shown to reduce rate of cognitive decline (estimate = 0.03, SE = 0.01, p = 0.00). ConclusionsThere is increasing evidence that participation in cognitively stimulating leisure activities may contribute to a reduction of risk of dementia and cognitive impairment in later life. Promoting involvement in such activities across lifespan could be an important focus for primary prevention strategies for governments and health services.
A systematic review of the relationship between behavioral and psychological symptoms (BPSD) and caregiver well-being
ABSTRACTBackgroundBehavioral and psychological symptoms in dementia (BPSD) are important predictors of institutionalization as well as caregiver burden and depression. Previous reviews have tended to group BPSD as one category with little focus on the role of the individual symptoms. This review investigates the role of the individual symptoms of BPSD in relation to the impact on different measures of family caregiver well-being. MethodsSystematic review and meta-analysis of papers published in English between 1980 and December 2015 reporting which BPSD affect caregiver well-being. Paper quality was appraised using the Downs and Black Checklist ( 1998). ResultsForty medium and high quality quantitative papers met the inclusion criteria, 16 were suitable to be included in a meta-analysis of mean distress scores. Depressive behaviors were the most distressing for caregivers followed by agitation/aggression and apathy. Euphoria was the least distressing. Correlation coefficients between mean total behavior scores and mean distress scores were pooled for four studies. Irritability, aberrant motor behavior and delusions were the most strongly correlated to distress, disinhibition was the least correlated. ConclusionsThe evidence is not conclusive as to whether some BPSD impact caregiver well-being more than others. Studies which validly examined BPSD individually were limited, and the included studies used numerous measures of BPSD and numerous measures of caregiver well-being. Future research may benefit from a consistent measure of BPSD, examining BPSD individually, and by examining the causal mechanisms by which BPSD impact well-being by including caregiver variables so that interventions can be designed to target BPSD more effectively.
The needs of people with dementia living at home from user, caregiver and professional perspectives: a cross-sectional survey
Background Few reports have been published about differences in perspectives on perceived needs among community-residing people with dementia, their family caregivers, and professionals. The aim of this study was to compare these perspectives. Method During 2006 and 2007, one-hundred and fifty two interviews of people with dementia and their caregivers about the needs of the person with dementia were performed by four professionals using The Camberwell Assessment of Need for the Elderly (CANE). Professionals’ views on met and unmet needs of people with dementia were obtained for the total sample, family caregivers’ perspectives were gained for 125 people with dementia, and people with dementia’s views on their own needs were obtained for 125 persons with dementia. Results People with dementia reported fewer needs compared with the reports of their caregivers and the professionals. The most frequent unmet needs reported by people with dementia, caregivers and professionals were in the areas of daytime activities, company, and psychological distress; however, people with dementia rated psychological distress as the commonest unmet need. Conclusions Since the priorities of people with dementia can be different from those of caregivers and professionals, it is important to consider all perspectives when making care plans. Thus, compliance with treatment of people with dementia and also their quality of life could be potentially improved by a more collaborative partnership with them.
The impact of individual Cognitive Stimulation Therapy (iCST) on cognition, quality of life, caregiver health, and family relationships in dementia: A randomised controlled trial
Cognitive stimulation therapy (CST) is a well-established group psychosocial intervention for people with dementia. There is evidence that home-based programmes of cognitive stimulation delivered by family caregivers may benefit both the person and the caregiver. However, no previous studies have evaluated caregiver-delivered CST. This study aimed to evaluate the effectiveness of a home-based, caregiver-led individual cognitive stimulation therapy (iCST) program in (i) improving cognition and quality of life (QoL) for the person with dementia and (ii) mental and physical health (well-being) for the caregiver. A single-blind, pragmatic randomised controlled trial (RCT) was conducted at eight study sites across the United Kingdom. The intervention and blinded assessment of outcomes were conducted in participants' homes. Three hundred fifty-six people with mild to moderate dementia and their caregivers were recruited from memory services and community mental health teams (CMHTs). Participants were randomly assigned to iCST (75, 30-min sessions) or treatment as usual (TAU) control over 25 wk. iCST sessions consisted of themed activities designed to be mentally stimulating and enjoyable. Caregivers delivering iCST received training and support from an unblind researcher. Primary outcomes were cognition (Alzheimer's Disease Assessment Scale-cognitive [ADAS-Cog]) and self-reported QoL (Quality of Life Alzheimer's Disease [QoL-AD]) for the person with dementia and general health status (Short Form-12 health survey [SF-12]) for the caregiver. Secondary outcomes included quality of the caregiving relationship from the perspectives of the person and of the caregiver (Quality of the Carer Patient Relationship Scale) and health-related QoL (European Quality of Life-5 Dimensions [EQ-5D]) for the caregiver. Intention to treat (ITT) analyses were conducted. At the post-test (26 wk), there were no differences between the iCST and TAU groups in the outcomes of cognition (mean difference [MD] = -0.55, 95% CI -2.00-0.90; p = 0.45) and self-reported QoL (MD = -0.02, 95% CI -1.22-0.82; p = 0.97) for people with dementia, or caregivers' general health status (MD = 0.13, 95% CI -1.65-1.91; p = 0.89). However, people with dementia receiving iCST rated the relationship with their caregiver more positively (MD = 1.77, 95% CI 0.26-3.28; p = 0.02), and iCST improved QoL for caregivers (EQ-5D, MD = 0.06, 95% CI 0.02-0.10; p = 0.01). Forty percent (72/180) of dyads allocated to iCST completed at least two sessions per week, with 22% (39/180) completing no sessions at all. Study limitations include low adherence to the intervention. There was no evidence that iCST has an effect on cognition or QoL for people with dementia. However, participating in iCST appeared to enhance the quality of the caregiving relationship and caregivers' QoL. The iCST trial is registered with the ISRCTN registry (identified ISRCTN 65945963, URL: DOI 10.1186/ISRCTN65945963).
Improving health-promoting self-care in family carers of people with dementia: a review of interventions
Providing care for a family member with dementia can leave little time for carers to look after their own health needs, which makes them more susceptible to mental and physical health problems. This scoping review aimed to explore potential health benefits of interventions aimed at improving health-promoting self-care in family carers of people with dementia. A scoping review was carried out using Arksey and O'Malley's methodological framework. EMBASE, MEDLINE, PsycINFO and Google Scholar were consulted. Original and peer-reviewed research published in English up to April 2017 were included. Publications were selected by two reviewers independently. Eight experts from several countries provided extra relevant information, which was triangulated with the review results. A narrative approach was used to describe and discuss the review findings. Seven interventions were identified. These were highly heterogeneous in content, method of delivery, and outcome measures. None was specifically focused on improving and evaluating health-promoting self-care, instead they often focused on health promotion and healthy lifestyle (eg, physical activity). Some of the multi-component interventions included \"self-care\" as a domain, but none used a specific measure of health-promoting self-care, so we were unable to affirm that the improvements found in the interventions were due to an improvement in this area. Interventions helped reduce carer depression and burden and increased quality of life, positive affect, and physical activity. The expert panel recommended to consider carers' preparedness and capacity to adhere to self-care practices, as well as carers' age and culture. Future interventions should be context specific, flexible, and person-centered. Psychosocial interventions may improve health-promoting self-care behavior, but more research is needed to establish efficacy. Interventions should be flexible, use a person-centered approach, be implemented with fidelity and use the right dosage.
A cross sectional survey on UK older adult’s attitudes to ageing, dementia and positive psychology attributes
Background With an increasingly ageing population worldwide, the predominant attitude towards ageing is still negative. Negative stereotypes have detrimental effects on individuals’ physical and mental health. Evidence is required about factors that may predict and change these views. This study aimed to investigate if an older person’s attitude towards dementia, their belief in a just world and sense of coherence is associated with their attitudes to ageing. Methods A 25-min online survey was completed by 2,675 participants aged 50 or over who were current residents of the United Kingdom (UK). Questions included demographics, overall health, dementia carer, dementia relative status and retirement status. Standardised scales used were the Attitudes to Ageing Questionnaire (AAQ), Dementia Attitudes Scale (DAS), Just World Scale (JWS) and Sense of Coherence Scale-13 (SOC). Data was analysed with descriptive, two-tailed bivariate Pearson’s correlations, simple, and hierarchical regression analyses. Results Attitudes to dementia, just world beliefs, and sense of coherence were all significantly positively correlated with AAQ-Total, with SOC sub-scale “Meaningfulness” showing the strongest correlation. In a hierarchical regression model, higher scores on SOC-Meaningfulness, DAS-Total and belief in a just world for oneself all predicted more positive attitudes to ageing. Conclusions The more positive an individual’s attitude to dementia and the stronger they hold the belief that the world is just and coherent, the more likely they are to display positive attitudes to ageing. This initial evidence helps create a greater understanding of the factors that drive attitudes and stigma and may have implications for public health messaging.
REMCARE: Pragmatic Multi-Centre Randomised Trial of Reminiscence Groups for People with Dementia and their Family Carers: Effectiveness and Economic Analysis
Joint reminiscence groups, involving people with dementia and family carers together, are popular, but the evidence-base is limited. This study aimed to assess the effectiveness and cost-effectiveness of joint reminiscence groups as compared to usual care. This multi-centre, pragmatic randomised controlled trial had two parallel arms: intervention group and usual-care control group. A restricted dynamic method of randomisation was used, with an overall allocation ratio of 1:1, restricted to ensure viable sized intervention groups. Assessments, blind to treatment allocation, were carried out at baseline, three months and ten months (primary end-point), usually in the person's home. Participants were recruited in eight centres, mainly through NHS Memory Clinics and NHS community mental health teams. Included participants were community resident people with mild to moderate dementia (DSM-IV), who had a relative or other care-giver in regular contact, to act as informant and willing and able to participate in intervention. 71% carers were spouses. 488 people with dementia (mean age 77.5)were randomised: 268 intervention, 220 control; 350 dyads completed the study (206 intervention, 144 control). The intervention evaluated was joint reminiscence groups (with up to 12 dyads) weekly for twelve weeks; monthly maintenance sessions for further seven months. Sessions followed a published treatment manual and were held in a variety of community settings. Two trained facilitators in each centre were supported by volunteers. Primary outcome measures were self-reported quality of life for the person with dementia (QoL-AD), psychological distress for the carer (General Health Questionnaire, GHQ-28). Secondary outcome measures included: autobiographical memory and activities of daily living for the person with dementia; carer stress for the carer; mood, relationship quality and service use and costs for both. The intention to treat analysis (ANCOVA) identified no differences in outcome between the intervention and control conditions on primary or secondary outcomes (self-reported QoL-AD mean difference 0.07 (-1.21 to 1.35), F = 0.48, p = 0.53). Carers of people with dementia allocated to the reminiscence intervention reported a significant increase in anxiety on a General Health Questionnaire-28 sub-scale at the ten month end-point (mean difference 1.25 (0.25 to 2.26), F = 8.28, p = 0.04). Compliance analyses suggested improved autobiographical memory, quality of life and relationship quality for people with dementia attending more reminiscence sessions, however carers attending more groups showed increased care-giving stress. Economic analyses from a public sector perspective indicated that joint reminiscence groups are unlikely to be cost-effective. There were no significant adverse effects attributed to the intervention. Potential limitations of the study include less than optimal attendance at the group sessions--only 57% of participants attended at least half of the intervention sessions over the 10 month period, and a higher rate of study withdrawal in the control group. This trial does not support the clinical effectiveness or cost-effectiveness of joint reminiscence groups. Possible beneficial effects for people with dementia who attend sessions as planned are offset by raised anxiety and stress in their carers. The reasons for these discrepant outcomes need to be explored further, and may necessitate reappraisal of the movement towards joint interventions. ISRCTN Registry ISRCTN42430123.
