| Outline of Final Research Achievements |
This study proposes a novel approach for the early detection of cognitive impairment in the elderly, in which we focused on the prosodic features of speech sound during the subject’s answers to the questionnaire; the first was to detect signal and prosodic signs of cognitive impairment, the second was to take a measurement of cerebral blood flow (CBF). We then have developed a prototype of prosody-CBF hybrid screening system and discussed the cost-effectiveness and the discrimination performance. Moreover, MCI group is divided into two subtypes of Nonamnestic-MCI (N-MCI) composed of ten participants and Amnestic-MCI (A-MCI) composed of nine participants. We will present a comparative analysis of CBF activation between CN, N-MCI, A-MCI, and AD, by statistical tests of between-group significant differences using fNIRS signals of oxy-Hb during the cognitive task.
