Alzheimer disease (AD) is characterised by a decrease of platelet Amyloid Precursor Protein forms ratio (APPr), which parallels symptoms' severity. Recent studies have suggested that cholesterol might play a role in the pathophysiology of AD by modulating Aβ production. Aim of this study was to evaluate the relationship between serum cholesterol levels and platelet APP processing in controls and AD. Sixty AD patients and 45 age-matched controls (CTRL) were investigated. Neuropsychological assessment, cholesterol dosage and APP forms' evaluation were performed on each subject. CTRL showed lower serum cholesterol levels compared to AD (P
