Clinical subtypes of dementia with Lewy bodies Lead Investigator: Estrella Morenas-Rodriguez Institution : Hospital de la Santa Creu i Sant Pau E-Mail : emorenas@santpau.cat Proposal ID : 826 Proposal Description: Our main goal is to describe clinical subtypes in dementia with Lewy bodies (DLB) supported on neuropathological differences. This description is crucial for further studies investigating the relationship between the clinical and pathological heterogeneity in this group of patients and its possible relationship with different molecular and pathogenic pathways with a role in future treatment options. Our specific objectives are: - To describe DLB phenotypes based on core features in a clinical cohort using a cluster analysis. - To replicate this analysis (based on core clinical features) in a independent pathological cohort of patients with a previous clinical diagnosis of DLB. - To analyse the neuropathological differences between these resultant clusters.
