Cerebral blood flow data during cognitive task execution is measured using a functional near infrared spectroscopy method, then characteristic amount extraction is performed after performing primitive analysis on the measured cerebral blood flow data. Then, by using the extracted characteristic amounts and a pre-built model for employing in determination of cognitive impairment, automatic determination is made into clinical diagnostic groups of normal (NC), mild cognitive impairment (MCI) and Alzheimer's disease (AD).
