AI and EEG Lead Advances in Detecting Cognitive Impairment in Older Adults
A recent interdisciplinary review published on arXiv (2607.28687) consolidates progress in identifying and addressing cognitive decline among the elderly, covering conditions from mild cognitive impairment (MCI) to dementia. It explores various methods, including neurophysiological signals (EEG), neuroimaging techniques (MRI, amyloid/tau PET), blood biomarkers, and digital indicators, all enhanced by AI, ML, and DL. The authors present a classification system, a validation methodology, an early-detection framework that connects screening with interventions, and comparative tables of techniques and factors. The review underscores that standard assessments frequently overlook initial signs of cognitive decline, particularly EEG markers, and stresses the importance of dependable validation. It aims to support researchers and clinicians in overcoming detection obstacles as the population ages, with a proposed submission date in 2026.
