Amyloid, p‐tau, neurofilament light, and α‐synuclein cerebrospinal fluid biomarkers across Alzheimer's disease, dementia with Lewy bodies, and Parkinson's disease
Abstract INTRODUCTION Mounting evidence suggests overlapping pathology across Alzheimer's disease (AD), dementia with Lewy bodies (DLB), and Parkinson's disease (PD), yet its extent and clinical implications remain unclear. METHODS Cerebrospinal fluid (CSF) amyloid beta (Aβ)42/40, phosphorylated tau 181 (p‐tau181), neu...
