Classification of Alzheimer's disease patients using metrics of oculo-motors.

Ocular information was observed during a set of dementia tests involving participants with Alzheimer’s Disease (AD), with a mild level of cognitive impairment (MCI), or in a control group. The number of participants was 26. Features of changes in pupil size and in the central position of both eyes of participants of all three types were compared. There are significant differences in some of the metrics between the types, in earlier test sessions. The possibility of classification was confirmed using the extracted features, and the contributions of some features were examined.
