If QOL(Quality of life) in demented patients, who are unable to communicate can be evaluated, it is useful for judgment of medical adaptation, or the judgment of a curative effect. The conventional QOL evaluations are questionnaire type and it can't be used for the patient who can't communicate. QOL evaluation (SF-8) and a face photograph were taken of the patients who can communicate, and facial expression analysis was performed by medical workers and OKAO Vision(R).The relationship between "sadness" of OKAO Vision(R) and mental health QOL is significant. It is expected that facial expression analysis is useful in QOL evaluation.
