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...

Diagnostic performance and prediction of clinical progression of plasma phospho-tau181 in the Alzheimer's Disease Neuroimaging Initiative
Molecular PsychiatryAbstractWhilst cerebrospinal fluid (CSF) and positron emission tomography (PET) biomarkers for amyloid-β (Aβ) and tau pathologies are accurate for the diagnosis of Alzheimer's disease (AD), their broad...

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...

Higher CSF sTREM2 attenuates ApoE4-related risk for cognitive decline and neurodegeneration
Molecular NeurodegenerationAbstractBackground: The Apolipoprotein E ε4 allele (i.e. ApoE4) is the strongest genetic risk factor for sporadic Alzheimer's disease (AD). TREM2 (i.e. Triggering receptor expressed on myeloid cells 2) is a...

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...

An Update on Blood-Based Biomarkers for non-Alzheimer Neurodegenerative Disorders
Nat Rev NeurolAbstractCerebrospinal fluid analyses and neuroimaging can identify the underlying pathophysiology at the earliest stage of some neurodegenerative disorders, but do not have the scalability needed for...

Association between insomnia and cognitive performance, gray matter volume, and white matter microstructure in cognitively unimpaired adults
Alzheimer's Research & TherapyAbstractBackground: Mounting evidence links poor sleep quality with a higher risk of late-life dementia. However, the structural and cognitive correlates of insomnia are still not well understood. The study...
