Improving the Quality of Life of People with Dementia through the Use of Socially Assistive Robots

Abstract

In less than 25 years, 37 million people are expected to have dementia and/or Alzheimer’s disease. This significant figure is a result of several factors, including increasing life expectancy and an ageing population in developing countries. Alzheimer’s disease, a form of dementia, is a progressive brain disorder that causes memory loss, and behavior and personality changes. People suffering from this disease become increasingly physically and cognitively impaired; they usually need help with all aspects of daily living. While there is currently no cure for dementia, special therapies (e.g., arts and crafts, music therapy) can help people with dementia to live as good a life as possible. We propose to use socially assistive robots as customized/individualized helpers as a complement to humans. This work proposes a new adaptive socially assistive robotic (SAR) system that aims to provide a customized protocol through motivation, encouragement, and companionship for users suffering from cognitive changes related to aging and/or Alzheimer’s disease. The robot aims to maintain/improve the user’s cognitive attention in a cognitive music game setup.
