Brain cholinergic terminal density utilizing [18F]‐fluoroethoxybenzovesamicol PET in adults with Down’s syndrome: Relationship to amyloid PET and cognitive performance

Abstract BACKGROUND Adults with Down syndrome (DS) have increased risk of Alzheimer’s disease (AD). The cholinergic system declines in AD, underlying many cognitive deficits. We investigated the relationship between amyloid accumulation and cholinergic terminal...
