Detecting behavioral and psychological symptoms of dementia using multimodal sensors

Keywords: Agitation detection, aggression detection, aging-in-place, assistive technology, people with dementia.

Overview of Research

Globally we are facing a healthcare crisis related to caring for a rapidly aging population who are suffering from a variety of chronic medical conditions, such as dementia. Caring for people with dementia is more complicated given the severity of dementia they suffer from and the degree of autonomy they need for the completion of their activities of daily living [1].

Behavioral and Psychological Symptoms of Dementia (BPSD), such as aggression and agitation, can cause enormous suffering for people with dementia and stress on caregivers including actions that disrupt care and safety, such as wandering, physical and verbal aggression, and treatment refusal.

Our research project will focus mainly on aggressive and agitated behaviors from BPSD as these behaviors have been reported to be very common among people with dementia and are regarded as very stressful behaviors for caregivers in providing care. The project intends to develop new approaches and methods that will be able to detect and identify aggressive and agitated behaviors in people with dementia. These approaches will also be able to predict the occurrences of these behaviors. The outcome of this research will be of great value to the caregivers and people with dementia. It will help reduce the burden of the caregivers and ensure the well-being of people with dementia.
