MRI Detects Early α-Synuclein in Asymptomatic, Clinic Patients

JAMA Network

About The Study: In this cohort study, seed amplification assays (SAA) α-syn+ was consistently associated with nucleus basalis of Meynert (NBM) atrophy already during asymptomatic stages. Further, in memory clinic cognitively impaired populations, SAA α-syn+ was associated with NBM atrophy, which partially mediated α-syn–induced attention/executive impairment.
