Systemic Inflammation and Neurodegenerative Risk

This research investigates the link between systemic inflammatory markers, such as the neutrophil-to-lymphocyte ratio (NLR) and platelet function, and the risk of Alzheimer's disease and related dementias.

Alzheimer Disease and Dementia Inverse Probability Weighting Neutrophil-to-Lymphocyte Ratio Longitudinal Data Analysis

Anchor result

Elevated NLR was independently associated with increased AD/ADRD risk across both NYU and VA cohorts, with a dose-response relationship.
