Description
Julien Dubois and co-authors develop a brain-based marker for mild cognitive impairment using a light-based scanning method, in a 2025 paper. Mild cognitive impairment is often missed in primary care. Early detection matters because support and planning work best early. The method, time-domain functional near-infrared spectroscopy, shines harmless light through the scalp to read brain activity.
Patients and healthy older adults took part in rest and task recordings. Tasks included naming words by category and by first sound. The team searched the signals for patterns that separate the groups. A reliable marker could give clinics a quick, objective screen. The device suits office settings better than large scanners. Further work must confirm accuracy in larger samples.
