Abstract

Constellation graphs for time-series data are very effective tool for displaying a physio-psychological index. In this study, we recorded fingertip pulse waves of elderly subjects, carried out chaos analysis on the plethysmogram data thus obtained, and examined their relationship with dementia. We discovered the Lyapunov exponent of the time series had a clear relationship with the severity of dementia and the communication skill of the elderly subjects. We could clearly demonstrate a relationship between dementia and the Lyapunov exponents using constellation graphs of the time series data.
