Importance: Early identification of Alzheimer disease (AD) is important for clinical management and affords the opportunity to assess potential disease-modifying agents in clinical trials. To our knowledge, this is the first report of a randomized trial to prospectively enrich a study population with prodromal AD (PDAD) defined by cerebrospinal fluid (CSF) biomarker criteria and mild […]
New criteria related to prodromal Alzheimer’s disease (AD) have been proposed to overcome the issue of heterogeneity of patients with mild cognitive impairment (MCI) and to better define patients in early stage AD. Only few therapeutic trials, if any, have been reported using this newly defined population. The objective of this study was to assess […]
Parkinson’s disease dementia (PDD) is associated with cholinergic deficits. This report presents an efficacy and safety study of the acetylcholinesterase inhibitor donepezil hydrochloride in PDD. PDD patients (n = 550) were randomized to donepezil (5 or 10 mg) or placebo for 24 weeks. Coprimary end points were the Alzheimer’s Disease Assessment Scale-cognitive subscale (ADAS-cog) and […]
Background: Prevention strategies are urgently needed to tackle the growing burden of Alzheimer’s disease. We aimed to assess efficacy of long-term use of standardised ginkgo biloba extract for the reduction of incidence of Alzheimer’s disease in elderly adults with memory complaints.; Methods: In the randomised, parallel-group, double-blind, placebo-controlled GuidAge clinical trial, we enrolled adults aged […]
Background: The ARGO study was a phase II, double-blind, placebo controlled, four parallel arm trial of tideglusib in Alzheimer’s disease (AD). Objective: To prove the clinical efficacy of an inhibitor of glycogen synthase kinase-3 (GSK-3), in AD. Methods: Mild to moderate (Mini-Mental State Examination (MMSE) score, 14–26) AD patients on cholinesterase inhibitor and/or memantine treatment […]
