Chatbots for dementia patients and caregivers need more work

Chatbots hold promise for dementia patient or caregiver support, but are still in their infancy, finds a paper published in the Journal of Medical Internet Research. None of the interactive digital apps tested by medical researchers and a computer scientist performed well on all testing criteria, and all the apps contained linguistic biases and usability challenges. The authors conclude that until developers produce evidence-based chatbots that have undergone end user evaluation it will be hard to evaluate their potential to adequately educate and support dementia patients and their caregivers.
