The September review found digital reminiscence — photos, videos and music used to prompt memories — eased social isolation in dementia. Across companion robots, touchscreen and multisensory tools, most studies reported better interaction and less loneliness.
The Erasmus University portal dates Rai and colleagues' systematic review early online to 16 Sept 2022 in Journal of Alzheimer's Disease 90(2):513-528 early online record. All studies showed some quality-of-life gain. This article explains what helped socially and what carers can do now.

Which digital tools were tested?
Four included studies offered companionship or reminiscence through digital pets or humanoid robots, named MARIO, NAO, Giraff and JustoCat. Other tools in the review supported family communication, engagement and multisensory stimulation, according to the IOS Press journal report IOS Press journal report.
Touchscreen programs presented personal photos, songs and life events for joint viewing. Multisensory tools added sound, light and touch to invite response. Companion robots invited talk, eye contact and daily routine.
How did social connection improve?
People with dementia joined in more often and stayed engaged longer during sessions. The IOS Press journal report notes better social inclusion or interaction in most studies, with reduced loneliness and isolation. Carers reported more conversation turns and shared enjoyment.
A separate scoping review of reminiscence-based digital storytelling supports that social result. More than half of its studies, six in total, facilitated social connectedness. Examples included preserving voices and photos to connect participants to future generations.
Who is affected, and what about memory?
People affected are mainly those living with dementia and their carers. The Cochrane Library review of Woods and colleagues linked individual reminiscence to cognition and mood across 22 trials with 1,972 participants Cochrane Library review. It linked group reminiscence to communication, with quality-of-life gains most promising in care homes.
Digital delivery did not add a memory advantage in the newest test. The ASHA Evidence Maps summary of Tran and colleagues found no significant global-cognition gain on the Mini-Mental State Examination versus traditional reminiscence or usual care. That test measures orientation, recall and attention, with only moderate certainty.
What are the limits and what helps now?
Results rest on small studies with diverse methods that are hard to compare, PubMed's summary notes. Only two studies involved people with dementia in design.
Only five technologies existed outside research settings. Reviewers urge co-designed, affordable person-centred tools for wider use. Carers can already use familiar media as prompts during visits and calls: Start with material the person already enjoys and keep sessions short and calm.
- choose one theme, such as childhood home, work or holidays
- play one photo set, video clip or song at a time
- pause and invite stories, then listen and follow up
- save names, dates and phrases to reuse next time
