- Design
- Multicentre randomised controlled trial with active control
- Population
- 56 nursing home residents with behavioural and psychological symptoms of dementia
- Primary outcome
- Change in Neuropsychiatric Inventory score
- Effect
- No significant between-group difference; well-being improved in both arms
This multicentre randomised trial in French nursing homes enrolled 56 residents with behavioural and psychological symptoms of dementia. They had twelve 45-minute group sessions over six weeks of either immersive virtual reality or non-digital cognitive stimulation.
Symptom scores on the Neuropsychiatric Inventory and apathy interview did not differ between groups, nor did overall well-being. In both arms, residents' immediate well-being improved during sessions, and social interaction was more frequent with cognitive stimulation. Two mild adverse events were reported.
The trial is small and was not designed to show equivalence, so it cannot rule out a modest added benefit of virtual reality. But it suggests the active ingredient is structured group activity and attention, not the headset. In Indian care settings, where budgets are tight, regular structured group sessions are a realistic, low-cost non-drug approach, and they should come before antipsychotics.
- Offer regular structured group activities to care home residents with distressing dementia symptoms.
- Prefer non-drug approaches before considering antipsychotics for behavioural symptoms.
- Do not assume virtual reality adds benefit over simpler group cognitive stimulation.
- Note each resident's response to sessions and adjust the programme accordingly.
Why it matters
It shifts attention from technology to the staff-led activity that seems to carry the benefit.
Don't overread it
A 56-resident trial designed for superiority; it cannot show the two approaches are equivalent.
The statistics, in plain English
No significant difference in a small trial means a large advantage for virtual reality is unlikely, but a modest one cannot be excluded.
