Abstract

Peripheral inflammation is probably involved in the pathogenesis of progressive supranuclear palsy (PSP) and it may be a common feature with Parkinson's disease (PD). The peripheral immune profile in PSP remains unclear, as well as whether the inflammatory pathways differ from those in PD. The neutrophil-to-lymphocyte ratio (NLR) has been proven to be a well-established biomarker of systemic inflammation. This study aimed to evaluate the peripheral immune profile in PSP compared with PD.
