Emotional robots are being tested as therapeutic agents for behavioral issues in Alzheimer's patients. Robotics continues to be a topic of debate in the scientific community concerning the elderly and degenerative diseases. Could robots facilitate communication among Alzheimer's patients? The World Alzheimer's Day on September 21st symbolizes efforts and actions to improve the lives of patients and their family caregivers, with the upcoming National Caregiver Day on October 6th likely underscoring the challenging role and societal implications it presents. The scientific community holds promising hopes for emotional robots in the care of elderly individuals with dementia. Amid ethical concerns and potential benefits, how should we view these "social" robots?
New robots designed to enhance the social behavior of elderly individuals with degenerative diseases could revolutionize the care of Alzheimer's patients. Alzheimer's disease is a significant public health concern, involving expensive medical care, the well-being of family caregivers, and the overall quality of life of patients. This is particularly relevant in an era where the aging population is increasing, and people wish to remain at home for as long as possible.
The scientific community is focusing its attention on these unique robots, often referred to as "social" or "companion" robots. They are specially designed to interact sophisticatedly with humans, and current studies are aimed at eliciting positive emotions in patients through these robots. Initial results have already demonstrated the ability of these robots to improve communication, social interaction, and overall well-being while reducing behavioral issues. Some ethical aspects and limitations related to the sensitive subject of human-robot interaction are still under discussion.
Paro, an emotional seal robot, has already been introduced in a specialized unit for elderly individuals with neurodegenerative diseases causing psycho-behavioral disorders. This study sought to analyze the emotional impact of this companion robot on individuals with severe Alzheimer's disease over an 8-month period. The results were generally very satisfactory and revealed the emergence of positive interactions and emotions, as well as a reduction in behavioral problems.
Currently, there is no known cure for Alzheimer's disease. Proposed solutions primarily focus on symptom management and improving the daily lives of patients. If robotics can overcome ethical concerns and certain development limitations while reducing behavioral issues and enhancing communication for these individuals, it could become a fundamental contribution to the fight against this disease, which, it should be noted, sees more than 200,000 new cases annually in UK.
