We have proposed two Alzheimer dementia (AD) detection methods to establish a methodology using non-contact mattress sensors. In this paper, we propose a method, combining our two conventional methods to complete each other and verify the effectiveness.
Specifically, for ADDCRARaH and ADDUCRRaH, which focus on the AD's circadian rhythm disorder characteristics of heartrate, the base of the method is switched the ratio of sine/cosine instability to the amplitude ratio by the stability of sine wave.
In subjects experiments of one AD patient, three healthy elderly, ten healthy middle-aged, and eight healthy young people, the accuracies were all in about 80%$sim$100%, equivalent to or better than the conventional methods. |
