Tau PET overlap index correlation with neuropathological findings

open access: yesAlzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract INTRODUCTION The tau positron emission tomography (PET) overlap index (OI) has shown promise in maximizing signal‐to‐noise for longitudinal tau PET imaging, particularly for early tau pathology, but requires validation against neuropathology.

The landscape of dementia research, diagnosis, treatment, and care in Latin America

open access: yesAlzheimer's &Dementia, Volume 22, Issue 3, March 2026.
Abstract Latin America is undergoing rapid population aging alongside a rising burden of dementia. While the region holds substantial potential for dementia risk reduction, challenges remain, such as delayed diagnoses, limited access to specialized care and biomarker testing, persistent stigma, and deep‐rooted structural inequities.

There are Plane Spanners of Maximum Degree 4

open access: yes, 2014
Let E be the complete Euclidean graph on a set of points embedded in the plane. Given a constant t >= 1, a spanning subgraph G of E is said to be a t-spanner, or simply a spanner, if for any pair of vertices u,v in E the distance between u and v in G is ...

Amyloid‐related default mode network hyperconnectivity and longitudinal decline in network distinctiveness in preclinical Alzheimer's disease

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION We investigated stage‐specific alterations in functional connectivity (FC) of the default mode network (DMN) across the Alzheimer's disease (AD) continuum and tested whether early amyloid beta (Aβ)–related changes in within‐DMN FC (DMN‐FCwithin) predicted longitudinal alterations in DMN between‐network connectivity (DMN‐FCbetween).

Association between brain volume and depression in Alzheimer's disease: Neuroimaging insights

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Alzheimer's disease (AD) often co‐occurs with depression, affecting cognitive function and quality of life. Understanding the neurobiological links between brain abnormalities and depressive symptoms is essential for effective treatment.

AI‐enhanced Centiloid quantification of amyloid PET images

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION The Centiloid scale is the standard for amyloid (Aβ) PET quantification in research and clinical settings. However, variability between tracers and scanners remains a challenge. METHODS This study introduces DeepSUVR, a deep learning method to correct Centiloid quantification, by penalizing implausible longitudinal trajectories ...

Importance of Reactive Agility and Change of Direction Speed in Differentiating Performance Levels in Junior Soccer Players: Reliability and Validity of Newly Developed Soccer-Specific Tests

open access: yesFrontiers in Physiology, 2018
Agility is a significant determinant of success in soccer; however, studies have rarely presented and evaluated soccer-specific tests of reactive agility (S_RAG) and non-reactive agility (change of direction speed – S_CODS) or their applicability in this

A network analysis to identify mediators of germline-driven differences in breast cancer prognosis. [PDF]

open access: yes, 2020
Identifying the underlying genetic drivers of the heritability of breast cancer prognosis remains elusive. We adapt a network-based approach to handle underpowered complex datasets to provide new insights into the potential function of germline variants ...
