Title:
ALZHEIMER-TYPE DEMENTIA DETERMINATION DEVICE, ALZHEIMER-TYPE DEMENTIA DETERMINATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/186275
Kind Code:
A1
Abstract:
This dementia determination device includes: an acquisition unit for acquiring information about a heart rate; a first estimation unit for estimating a circadian rhythm of the heart rate from the information about the heart rate; a second estimation unit for estimating a non-circadian rhythm of the heart rate that is different from the circadian rhythm of the heart rate; and a determination unit for determining whether the Alzheimer-type dementia is present on the basis of a signal amplitude of the estimated circadian rhythm of the heart rate and a signal amplitude of the estimated non-circadian rhythm of the heart rate.
