The paper models disease progression in Lewy body disorders using neuropathological data, identifying three distinct trajectories of alpha-synuclein pathology with different clinical associations.

This study finds that severe hyposmia (reduced sense of smell) is a distinguishing feature between dementia with Lewy bodies and Alzheimer’s disease dementia, based on neuropathological confirmation.

This study compares cognitive decline rates in Alzheimer's disease with and without clinically undiagnosed Lewy body disease, finding faster decline in those with undiagnosed Lewy body disease.
