Clinicopathologic and genetic features of multiple system atrophy with Lewy body disease.

ABSTRACT:

Background

Abnormal aggregates of α-synuclein are pathologic hallmarks of multiple system atrophy (MSA) and Lewy body disease (LBD). LBD sometimes coexists with MSA, but the impact of co-pathology, particularly diffuse LBD, on presentation of MSA has not been studied. We aimed to determine the frequency and clinicopathologic features of MSA with LBD (MSA+LBD).

Methods

Using hematoxylin & eosin and α-synuclein-immunostained slides, we assessed the distribution and severity of LBD in 230 autopsy-confirmed MSA patients collected from 1998 to 2018. Alzheimer-type pathology was assessed to assign the likelihood of clinical presentations of dementia with Lewy body (DLB) using the consensus criteria for DLB. We reviewed medical records to characterize clinicopathologic features of
