Dementia Care Research and Psychosocial Factors

Area of Science:

• Gerontology
• Human-Computer Interaction
• Neuroscience

Background:

• Dementia affects approximately one-third of individuals aged 85+, with apathy impacting 50-70% of those with dementia.
• Apathy in dementia leads to disengagement and social withdrawal, negatively affecting quality of life.
• Social robots offer a potential avenue to stimulate memory and encourage activity participation in individuals with dementia.

Purpose of the Study:

• To investigate the efficacy of a socially interactive robot delivering gossip-based conversations to re-engage individuals with dementia.
• To assess the impact of this novel intervention on activity engagement, apathy, cognitive function, mood, and quality of life.

Main Methods:

• A pilot study involved a socially interactive robot programmed with positive, familiar, and activity-based gossip.
• The robot engaged 8 participants in a memory care facility twice weekly in conversations.
• A two-tailed paired t-test analyzed pre- and post-intervention assessment scores.

Main Results:

• Participants demonstrated increased engagement in previously discontinued activities, alongside improved mood and social interaction.
• Cognitive function (MoCA) improved in 6 participants (p=0.0087), and apathy levels (Apathy Evaluation Scale) decreased in all (p=0.00024).
• Quality of life (QoL-AD) improved for all participants (p=0.0076), and mood (Geriatric Depression Scale) improved for four (p=0.025).

Conclusions:

• Social robots utilizing gossip-based interactions present a novel, non-pharmacological strategy for dementia care.
• This approach shows potential for re-engaging individuals with dementia in meaningful activities.
• The intervention may enhance cognitive function, reduce apathy, and improve overall well-being in dementia care settings.
