Caregiver-in-the-Loop AI: A Simulation-Based Feasibility Study for Dementia Task Verification

Abstract: Caregivers of people living with dementia (PLwD) experience stress when verifying whether tasks are truly completed, even with digital reminder systems. Generative AI, such as GPT-4, may help by automating task verification through follow-up questioning and decision support. This feasibility study evaluates an AI-powered task verification system integrated with digital reminders for PLwD. It examines (1) GPT-4's ability to generate effective follow-up questions, (2) the accuracy of an AI-driven response flagging mechanism, and (3) the role of caregiver feedback in refining system adaptability. A simulated pipeline was tested on 64 anonymized reminders. GPT-4 generated follow-up questions with and without contextual information about PLwD routines. Responses were classified into High, Medium, or Low concern, and simulated caregiver feedback was used to refine outputs. Results show that contextual information and caregiver input improved the clarity and relevance of AI-generated questions. The flagging system accurately identified concerns, particularly for safety-critical tasks, though subjective or non-urgent tasks remained challenging. Findings demonstrate the feasibility of AI-assisted task verification in dementia care. Context-aware AI prompts and caregiver feedback can enhance task monitoring, reduce caregiver stress, and strengthen PLwD support. Future work should focus on real-world validation and scalability.
