| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Pupil light reflex (PLR) for 1 second chromatic stimuli was analysed to develop a procedure of detecting Alzheimer's Disease (AD) patients. Features were calculated from waveforms of PLRs which reacted for three colors in two levels of brightness, and two factors were extracted using factor analysis. There are significant differences in factor scores for some conditions between AD and control groups. Logistic regression analysis was employed to estimate a probability of being AD patient using factor scores. Model performances with factor scores of observed conditions were evaluated, and parameters of models were estimated using a MCMC technique. |
