Many studies have suggested the possibility of using functional near-infrared spectroscopy (fNIRS) devices as neuroimaging tools in various patients. We aimed to evaluate whether fNIRS to measure the prefrontal cortex (PFC fNIRS) is suitable as a screening tool for cognitive impairments. Sixty participants, divided into normal, mild cognitive impairment, and dementia groups, were instructed to wear an fNIRS device during cognitive assessments to assess whether there is a significant difference in the PFC activity between the groups. A significant difference in PFC activity between the groups was observed during the verbal fluency test. Moreover, the PFC activity during the verbal fluency test significantly correlated with the existing cognitive screening tool score. These results suggested that PFC fNIRS can be used as a cognitive impairment screening tool for mild cognitive…
