RBD signals increased risk of Parkinson's, dementia

A new study suggests that a sleep disorder, Rapid Eye Movement (REM) behavior disorder (RBD), may indicate an increased risk of developing Parkinson's disease or dementia. Nearly 90% of individuals with RBD are likely to develop these neurodegenerative diseases. Researchers found that RBD, where people act out their dreams, can serve as an early warning sign. The study, using MRI scans and machine learning, identified distinct brain atrophy patterns associated with Parkinson's and Lewy Body Dementia (LBD). The study's findings highlight the importance of early detection. The team now aims to identify factors contributing to brain deterioration to improve patient care and potentially slow disease progression.
