The Feasibility of a Mindfulness Intervention for Depression in People with Mild Dementia: A Pilot Randomized Controlled Trial.

OBJECTIVES: This preliminary study aimed to establish the feasibility of running an adapted Mindfulness Based Cognitive Therapy (MBCT) intervention for people with mild dementia and depression. It also aimed to conduct an exploratory analysis as to whether the MBCT intervention would lead to greater improvements in measures of depression, anxiety, quality of life and cognition, as compared to treatment as usual (TAU). METHODS: A single-blind, multisite, feasibility randomized controlled trial was used. People with dementia and depression were recruited from participating memory services. Twenty participants were randomized to either an adapted MBCT and TAU group (n = 10) or TAU (n = 10). Measures of depression, anxiety, quality of life (QOL), and cognition were assessed at baseline and follow-up. RESULTS: The intervention was feasible in terms of high attendance and low levels of attrition. It was not judged feasible to recruit enough participants within the recruitment time-frame. The MBCT group did not show significant improvements in depression, anxiety, QOL, and cognition at follow-up, as compared to TAU. CONCLUSION: There is currently inadequate evidence to recommend this adapted MBCT intervention for people with dementia for the treatment of depression within memory services. The MBCT intervention needs redevelopment and piloting before further testing in an RCT.

Mindfulness-based cognitive therapy for depression in people with dementia: A qualitative study on participant, carer and facilitator experiences.

BACKGROUND: Depression in dementia is common and associated with negative health outcomes. Mindfulness-based cognitive therapy is a recommended treatment of choice for recurrent depression, but its use for depression in dementia is yet to be assessed. OBJECTIVE: This study aimed to investigate the experiences of people with depression and dementia who participated in the mindfulness-based cognitive therapy intervention and those of their carers and facilitators. METHODS: This qualitative study was nested within a randomised controlled feasibility study. Semi-structured interviews were conducted with 18 people (eight people with dementia and depression, six carers and four course facilitators). Thematic analysis was used to analyse the data. FINDINGS: Several beneficial effects of mindfulness-based cognitive therapy were described. These were a sense of shared suffering among the group, greater present moment focus and awareness, various positive emotional changes, including greater self-compassion, and benefits for carers, such as the reduction of anxiety. Specific aspects of the programme were identified as particularly useful, including facilitator characteristics and certain mindfulness practices. Carer involvement, cognitive difficulties and barriers to home practice influenced engagement with the course. Facilitators described adaptations made to mindfulness-based cognitive therapy and suggested additional modifications for future groups. CONCLUSION: Results of this process evaluation suggest that mindfulness-based cognitive therapy is a potentially useful intervention for people with depression in dementia, but that further adaptation of the intervention is required to make the programme suitable for this clinical population.

Mindfulness-Based Cognitive Therapy (MBCT) programme for depression in people with early stages of dementia: study protocol for a randomised controlled feasibility study.

BACKGROUND: Depression and dementia are major public health problems in the UK. Depression in early-stage dementia is very common and significantly reduces quality of life, speeds cognitive decline and increases functional impairment. Mindfulness-Based Cognitive Therapy (MBCT) is an effective depression prevention programme, and the National Institute for Clinical Excellence (NICE) has suggested that MBCT is a priority for implementation. Alongside this, there is emerging evidence demonstrating promising results in relation to the benefits of adapted mindfulness interventions for people with dementia, suggesting that it could be beneficial in reducing depressive symptoms and in slowing deterioration in cognitive functions such as sustained attention, distraction inhibition and task switching. METHODS: The design is a single-blind randomised controlled feasibility trial. Participants with mild to moderate depression and early stages of dementia will be recruited from the participating memory services. Participants will receive either immediate or delayed access to an 8-week MBCT programme. Participants will be assessed by a blind assessor and complete cognitive and mood-related outcome measures before and after the intervention. This feasibility study will test the trial design and assess recruitment, retention, acceptability and adherence, as well as providing preliminary efficacy data. DISCUSSION: This study will inform the design and sample size for a future full randomised controlled trial (RCT), which will be carried out to determine the effectiveness of the intervention in reducing depressive symptoms in people with early stages of dementia.
