Assisted living - an agent based architecture for automated cognitive assessment

Dementia is a broad category for chronic and progressive diseases affecting the brain, which are defined as a decline in cognitive abilities severe enough to affect performance of activities of daily living. Accurate diagnosis is essential to support pro-active and personalised care practices. Current assessments of Dementia are designed to measure cognitive abilities in isolated and artificial situations. The benefits of these tests are limited as testing may not translate well to real world situations. The vision is for assessment and assistive systems that can be kept consistently in tune with the needs of their users, by more easily incorporating the input from human experts and by using an explicit user model. A customised agent architecture was implemented to enable discrete event simulations of ADLs, and to track human actions in a sensorised kitchen environment. A cognitive user model was developed based on declarative and semantic memory, and was evaluated on a common cognitive assessment with a data set of 149 older adults. An automated cognitive assessment protocol was proposed and implemented based on these observations of kitchen ADLs, and evaluated with a user study of 30 participants. A system architecture linking automated assessment and automated assistance was proposed.
