Studies in the library tested several kinds of home-based help: occupational therapy, a coaching programme for the person and caregiver (COPE), care management through primary care, and home advisors who support caregivers, and the smaller trials reported benefits for daily function, behavioural symptoms or caregiver wellbeing. The largest trial in the library, D-CARE (2176 pairs of people with dementia and caregivers), found no significant difference in behavioural symptoms or caregiver strain between its programmes and usual care.
What the studies found
A 2008 BMJ trial of 135 patients aged 65 or older with mild to moderate dementia living in the community, and their primary care givers, tested 10 sessions of occupational therapy over five weeks, delivered in a memory clinic, a day clinic and participants' homes. The sessions trained patients to use aids that compensate for cognitive decline and care givers in coping behaviours and supervision. At three months there was a significant difference of 36% in the proportion of successful treatments, and total mean costs were 1748 euros lower in the intervention group, mainly in informal care.
The COPE randomized trial in JAMA (2010) tested a home-based, nonpharmacologic biobehavioral intervention in community-living dyads, with 237 randomized. At 4 months, compared with controls, COPE patients had less functional dependence (adjusted mean difference 0.24) and less dependence in instrumental activities of daily living (0.32), and improved engagement (0.12).
A 2006 JAMA trial of 84 patients tested collaborative care for Alzheimer's disease in primary care, in which caregivers' reports triggered protocols for behavioural and psychological symptoms. Intervention patients had significantly fewer such symptoms on the total NPI score at 12 months (mean difference -5.6) and at 18 months (-5.4), caregivers reported less distress at 12 months, and the gains were achieved without significantly increasing use of antipsychotics or sedative-hypnotics.
A 2008 randomized trial in Goa, India, enrolled 81 families and tested a home care programme in which Home Care Advisors, supervised by a counselor and a psychiatrist, gave caregivers information on dementia and guidance on behaviour management. The intervention led to a significant reduction in caregiver mental-health scores (GHQ, -1.12) and in distress due to behavioural disturbances (NPI-D, -1.96); reductions in caregiver burden and patients' activities of daily living were not significant.
The largest trial, D-CARE (JAMA, 2025), randomized 2176 dyads to a health-system programme, a community-based programme or usual care. No significant differences existed between the 2 treatments or between treatments and usual care for the primary outcomes, behavioural symptoms and caregiver strain; only the secondary outcome of caregiver self-efficacy was significantly higher for both treatments than usual care (15.1 and 15.2 vs 14.4).
For help near the end of life at home, a 2019 systematic review in Palliative Medicine retrieved eight relevant studies of home palliative care interventions in dementia, none of which was of high quality. The weak evidence showed potential benefits for end-of-life outcomes such as behavioural disturbances, and the review highlights the paucity of high-quality dementia-specific research.
What remains uncertain
The results are mixed. The smaller trials above reported benefits, while D-CARE, the largest, did not find differences in its primary outcomes. The programmes were different from each other, so the studies do not show which kind of help works best or for whom.

The D-CARE record lists its own limits: the usual-care arm was small (n=144), outcomes were caregiver-reported, the horizon was 18 months, and it ran partly during the COVID-19 pandemic. The Goa trial was small and some participants died or did not finish.

The library holds no study that tells a family which of these services exist where they live, who qualifies, or how a particular service is paid for. Those are questions for a social worker, care manager or clinician who knows the person and the local services.

Questions
- What kinds of help at home have been studied for dementia?
- Trials in the library tested occupational therapy, the COPE programme for the person and caregiver, collaborative care through primary care, and home advisors supporting caregivers.
- Does home help for dementia work?
- Results are mixed. In a trial of 135 patients, occupational therapy produced a significant difference of 36% in successful treatments at three months, while the 2025 D-CARE trial of 2176 dyads found no significant differences in its primary outcomes between its programmes and usual care.
- Is there evidence for caregiver support at home?
- In a 2008 randomized trial in Goa, India, a home care programme led to a significant reduction in caregiver mental-health scores (GHQ, -1.12) and in distress due to behavioural disturbances (NPI-D, -1.96).
