AI Identifies Lewy-Body Dementia Through Voice Emotion Changes

Researchers at the University of Tsukuba and IBM Research have used deep neural networks to identify disease-specific reductions in emotional vocalization in Lewy body dementia, distinguishing it from Alzheimer's disease. This reduction in vocal emotional expressivity is linked to cognitive impairment and brain region atrophy, suggesting that vocal emotion analysis could aid in early detection and proper care for Lewy body dementia patients.
