Spatial-Temporal Patterns of Amyloid-β Accumulation: A Subtype and Stage Inference Model Analysis
NeurologyAbstractBackground and objectives: Currently, amyloid-β (Aβ) staging models assume a single spatial-temporal progression of amyloid accumulation. We assessed evidence for Aβ accumulation subtypes by applying...

Age, sex and APOE-ε4 modify the balance between soluble and fibrillar β-amyloid in non-demented individuals: topographical patterns across two independent cohorts
Mol Psychiatry.AbstractAmyloid (Aβ) pathology is the earliest detectable pathophysiological event along the Alzheimer's continuum, which can be measured both in the cerebrospinal fluid (CSF) and by Positron Emission...

Soundtrack of life: An fMRI study
Behav Brain Res.AbstractMost people have a soundtrack of life, a set of special musical pieces closely linked to certain biographical experiences. Autobiographical memories (AM) and music listening (ML) involve complex...

CSF Synaptic Biomarkers in the Preclinical Stage of Alzheimer Disease and Their Association With MRI and PET: A Cross-sectional Study
NeurologyAbstractObjective: To determine whether CSF synaptic biomarkers are altered in the early preclinical stage of the Alzheimer's continuum and associated with Alzheimer's disease (AD) risk factors, primary...

Associations between air pollution and biomarkers of Alzheimer's disease in cognitively unimpaired individuals
Environ IntAbstractBackground: Air quality contributes to incidence of Alzheimer's disease (AD) although the underlying neurobiological mechanisms are unclear. This study was aimed to examine the association between air...

Perivascular spaces are associated with tau pathophysiology and synaptic dysfunction in early Alzheimer's continuum
Alzheimers Res TherAbstractBackground: Perivascular spaces (PVS) have an important role in the elimination of metabolic waste from the brain. It has been hypothesized that the enlargement of PVS (ePVS) could be affected by...

Strategies to reduce sample sizes in Alzheimer's disease primary and secondary prevention trials using longitudinal amyloid PET imaging
Alzheimers Res TherAbstractBackground: Detecting subtle-to-moderate biomarker changes such as those in amyloid PET imaging becomes increasingly relevant in the context of primary and secondary prevention of Alzheimer's disease...

A multisite analysis of the concordance between visual image interpretation and quantitative analysis of [ 18 F]flutemetamol amyloid PET images
Eur J Nucl Med Mol ImagingAbstractBackground: [18F]flutemetamol PET scanning provides information on brain amyloid load and has been approved for routine clinical use based upon visual interpretation as either negative (equating to...

Amyloid positive individuals with subjective cognitive decline present increased CSF neurofilament light levels that relates to lower hippocampal volume
Neurobiol AgingAbstractNeurofilament light chain (NfL) is an axonal protein that when measured in cerebrospinal fluid (CSF) serves as a biomarker of neurodegeneration. We aimed at investigating the association among CSF NfL...

Visual assessment of [18F]flutemetamol PET images can detect early amyloid pathology and grade its extent
European Journal of Nuclear Medicine and Molecular ImagingAbstractPurpose: To investigate the sensitivity of visual read (VR) to detect early amyloid pathology and the overall utility of regional VR.
