Association of Glucocerebrosidase Mutations With Dementia With Lewy Bodies

Abstract
Lewy body (LB) disorders include Parkinson disease (PD), dementia with LBs (DLB), and LB variant of Alzheimer disease (LBV-AD). They have in common pathologically the presence of aberrant intracellular α-synuclein aggregates (LBs and Lewy neurites). Clinically, these disorders tend to have symptoms of parkinsonism and dementia.1,2 It is common for Alzheimer disease (AD) and LB disorders to overlap; both may occur in the same brain (eg, LBV-AD).
