α‐Synuclein seed amplification assay detects Lewy body co‐pathology in autosomal dominant Alzheimer’s disease late in the disease course and dependent on Lewy pathology burden

Abstract INTRODUCTION Amyloid beta and tau pathology are the hallmarks of sporadic Alzheimer’s disease (AD) and autosomal dominant AD (ADAD). However, Lewy body pathology (LBP) is found in ≈ 50% of AD and ADAD brains. METHODS Using an α-synuclein seed...
