Rhythmic Entrainment and Alertness in Lewy Body Dementia (REACT-DLB)

From the registry

This study will examine how people with dementia with Lewy bodies (DLB) or mild cognitive impairment with Lewy bodies respond to rhythmic auditory cues, and whether changes in alertness affect ability to synchronize movements to a rhythm. Participants will complete a single study visit that includes finger-tapping tasks performed with and without rhythmic auditory cues at different tempos. Brain activity will be recorded using electroencephalography (EEG), and tapping performance will be measured. Participants and the participant's study partners will also provide repeated ratings of alertness during the visit. The study aims to identify brain and behavioral measures of rhythmic synchronization and determine whether these measures change depending on a participant's level of alertness. The findings will help guide the development of future rhythm-based interventions for people with DLB.
