Plasma levels of soluble amyloid precursor protein β in symptomatic Alzheimer’s disease

TL;DR: In this paper, the authors reported that plasma levels of soluble amyloid precursor protein β (sAPPβ) were significantly lower in patients with symptomatic AD (21 with mild cognitive impairment due to AD and 44 with AD dementia) with AD-typical cerebral hypometabolic pattern compared with 27 cognitively healthy elderly individuals without preclinical AD.
Journal ArticleDOI

Unlocking the mystery of biomarkers: A brief introduction, challenges and opportunities in Parkinson Disease

TL;DR: The present role of genetic and biochemical biomarkers in Parkinson Disease is reviewed and areas where the use of biomarkers may benefit clinical trial planning, as well as clinical care through the application of a "precision medicine" approach, in the near term are highlighted.
Journal ArticleDOI

Finding specificity in structural brain alterations through Bayesian reverse inference

TL;DR: A new analytical instrument capable of innovating the methodological approach to the investigation of brain pathology is put forward, which was employed, as a proof of concept, on voxel‐based morphometry data of schizophrenia and Alzheimer's disease.

The Amyloid Hypothesis of Alzheimer's Disease: Progress and Problems on the Road to Therapeutics

TL;DR: It has been more than 10 years since it was first proposed that the neurodegeneration in Alzheimer's disease (AD) may be caused by deposition of amyloid β-peptide in plaques in brain tissue and the rest of the disease process is proposed to result from an imbalance between Aβ production and Aβ clearance.
Journal ArticleDOI

Complex brain networks: graph theoretical analysis of structural and functional systems

TL;DR: This article reviews studies investigating complex brain networks in diverse experimental modalities and provides an accessible introduction to the basic principles of graph theory and highlights the technical challenges and key questions to be addressed by future developments in this rapidly moving field.
Journal ArticleDOI

Hypothetical model of dynamic biomarkers of the Alzheimer's pathological cascade

TL;DR: This work proposes a model that relates disease stage to AD biomarkers in which Abeta biomarkers become abnormal first, before neurodegenerative biomarkers and cognitive symptoms, and neurodegnerative biomarker become abnormal later, and correlate with clinical symptom severity.
