Comparative Analysis of Different Definitions of Amyloid-β Positivity to Detect Early Downstream Pathophysiological Alterations in Preclinical Alzheimer
J Prev Alzheimers DisAbstractAmyloid-β (Aβ) positivity is defined using different biomarkers and different criteria. Criteria used in symptomatic patients may conceal meaningful early Aβ pathology in preclinical Alzheimer...

Quantitative informant- and self-reports of subjective cognitive decline predict amyloid beta PET outcomes in cognitively unimpaired individuals independently of age and APOE ε4
Alzheimers Dement (Amst)AbstractIntroduction: Amyloid beta (Aβ) pathology is an Alzheimer's disease early hallmark. Here we assess the value of longitudinal self- and informant reports of cognitive decline to predict Aβ positron...

Novel tau biomarkers phosphorylated at T181, T217 or T231 rise in the initial stages of the preclinical Alzheimer's continuum when only subtle changes in Aβ pathology are detected
EMBO Molecular MedicineAbstractIn Alzheimer's disease (AD), tau phosphorylation in the brain and its subsequent release into cerebrospinal fluid (CSF) and blood is a dynamic process that changes during disease evolution. The main...

Amyloid beta, tau, synaptic, neurodegeneration, and glial biomarkers in the preclinical stage of the Alzheimer's continuum
Alzheimer's DementiaAbstractIntroduction: The biological pathways involved in the preclinical stage of the Alzheimer's continuum are not well understood.
Methods: We used NeuroToolKit and Elecsys® immunoassays to measure...

Sex differences of longitudinal brain changes in cognitively unimpaired adults
Journal of Alzheimer's DiseaseAbstractBackground: There is increasing evidence that AD progression differs by sex.
Objective: The aim of this work was to determine sex differences in the association of baseline levels of cerebrospinal...

Effect of BDNF Val66Met Polymorphism on Hippocampal Subfield Volumes and Compensatory Interaction with APOE-ε4
Brain Structure and FunctionAbstractBackground: Current evidence supports the involvement of brain-derived neurotrophic factor (BDNF) Val66Met polymorphism, and the ε4 allele of APOE gene in hippocampal-dependent functions. Previous...

The relation between APOE genotype and cerebral microbleeds in a cognitively unimpaired middle- and late-aged individuals
Neurobiology of AgingAbstractPositive associations between cerebral microbleeds (CMBs) and APOE-ε4 (apolipoprotein E) genotype have been reported in Alzheimer's disease, but show conflicting results. We investigated the effect of...

APOE-e4 shapes the cerebral organization in cognitively intact individuals as reflected by structural gray matter networks
Cerebral CortexAbstractGray matter networks (GMn) provide essential information on the intrinsic organization of the brain and appear to be disrupted in Alzheimer's disease (AD). Apolipoprotein E (APOE)-ε4 represents the...

Simulating the Effect of Cerebral Blood Flow Changes on Regional Quantification of [ 18 F]flutemetamol and [ 18 F]florbetaben Studies
J Cereb Blood Flow MetabAbstractGlobal and regional changes in cerebral blood flow (CBF) can result in biased quantitative estimates of amyloid load by PET imaging. Therefore, the current simulation study assessed effects of these...
