Cross-sectional analysis characterizes cognitive impairment and neuroimaging markers in dementia with Lewy bodies and Parkinson disease, highlighting distinct phenotypes.

Key Points

De novo DLBRBD patients showed significantly poorer cognitive performance than de novo PD and PDRBD patients, with major deficits in attention and executive functions.
Neuroimaging results indicated reduced glucose metabolism in key brain areas for de novo DLBRBD, while dopaminergic function was lowest in de novo PD patients.
The study utilized a cross-sectional design with neuropsychological assessments and advanced neuroimaging techniques to evaluate clinical and neuroimaging characteristics across phenotypes.
Findings underscore the unique neuroimaging and clinical profiles within the α-synucleinopathy spectrum, suggesting the need for tailored assessments and interventions.
