RecruitingPhase 4ProcedureElucidating the Role of Cholinergic Degeneration in Cognitive Fluctuations in Lewy Body DementiaThe proposed study aims to address the critical gaps in understanding the mechanisms of CF (Cognitive Fluctuations) by leveraging recently emerged molecular biomarkers, advanced neuroimaging techniques to assess measures of cholinergic degeneration, and synchronous EEG and assessments of attention. One of the overarching innovations of study is combining all of these assessments into one integrated research plan
