Dementia Care Research and Psychosocial Factors

While often perceived negatively, gossip can act as a powerful social catalyst, reigniting interest in familiar activities among individuals affected by dementia. Studies indicate that 20-40% of community-dwelling older adults experience symptoms of apathy, while approximately one-third of individuals aged 85 and older have some form of dementia. Apathy affects 50-70% of people with dementia, contributing to disengagement and social withdrawal. Social robots with conversational capabilities may leverage gossip to stimulate memory recall and encourage participation in meaningful activities.

We developed a socially interactive robot programmed to deliver positive, familiar, and activity-based gossip to individuals with dementia. A pilot study was conducted in a memory care facility, where the robot engaged participants, twice a week in conversations designed to rekindle interest in previously abandoned activities. A two-tailed paired t-test was performed on pre- and post-intervention assessment scores to evaluate the effectiveness of the approach.

Participants (n = 8) showed increased engagement in activities that they had previously discontinued, with improvements in mood and social interaction. Cognitive function, assessed using the MoCA, improved for 6 participants (p = 0.0087). Apathy levels, measured by the Apathy Evaluation Scale, decreased for all participants (p = 0.00024). Quality of life, assessed through the QoL-AD, improved for all participants (p = 0.0076). Mood, evaluated using the Geriatric Depression Scale (GDS), improved for four participants (p = 0.025).

Social robots delivering gossip-based interactions offer a novel, non-pharmacological approach to re-engaging individuals with dementia in meaningful activities. This intervention has the potential to enhance cognitive function, reduce apathy, and improve overall well-being in dementia care settings.
