Empirical pathological staging and subtyping of TDP-43 proteinopathies
Background: Pathological aggregation of tar DNA-binding protein 43 (TDP-43) in the brain is the primary cause of many cases of frontotemporal lobar degeneration (FTLD), amyotrophic lateral sclerosis (ALS) and limbic-predominant age-related TDP-43 encephalopathy (LATE). It is therefore imperative to establish empirical staging systems to characterize and distinguish stereotypical patterns and commo
