Clinical and Biologic Characterization of a 3-Level Centiloid-Based Classification of Amyloid PET.

Findings support a 3-level interpretation of amyloid PET beyond binary classification and highlight the clinical relevance of the intermediate zone, which delineates biologically and clinically distinct stages along the amyloid continuum.

Metabolism Pathway Blood Proteomic Differences in Lewy Body Dementia Compared to Alzheimer’s Disease

Dementia with Lewy Bodies (DLB) is the most common neurodegenerative dementia after Alzheimer’s disease (AD), but it remains challenging to diagnose due to overlapping symptoms and mixed pathologies. This pilot study tested whether DLB has different metabolic blood proteomic profiles compared to AD and controls. Serum...

Plasma Biomarkers for Neocortical Tau Burden.

This multicohort study demonstrated how including additional plasma proteins significantly enhanced the performance of p-tau217 in predicting advanced tau pathology among amyloid-positive individuals, suggesting a multiprotein approach may offer a viable and scalable alternative to tau PET staging in clinical or resear...

Exploring longitudinal relationships among Alzheimer's disease biomarkers

While most studies of Alzheimer's disease (AD) examine cross‐sectional relationships among biomarkers, longitudinal relationships are also highly relevant.

Predicting continuous amyloid PET levels with CSF and plasma brain‐derived p‐tau217

Conventional phosphorylated tau (p‐tau)217 reliably identifies amyloid positron emission tomography (PET) positivity, but its ability to capture the full Aβ continuum is limited.

Lifestyle and psychosocial protective factors drive healthy aging and modulate inflammatory and metabolic pathways.

The present study paves the way for further investigations on the biological mechanisms underlying resilient aging, while further demonstrating the key protective role of individual habits and psychosocial characteristics during the life course.

Plasma p-tau217 and NfL predict incident dementia in the community

These findings support the use of blood-based biomarkers for population-level dementia risk stratification, underscore the value of combining markers to improve prognostic precision, and can aid clinicians using plasma p-tau217 or NfL in interpreting dementia risk.

Blood-based immunophenotyping of T cell profiles in patients with neurodegenerative disorders.

Examination of blood-based T-cell profiles across a range of neurodegenerative dementias provides evidence that T-cell dysregulation is not unified in patients with neurodegenerative diseases and observes different involvement across different dementia types establishing adaptive immunity as a key contributor to diseas...

CSF and plasma tau biomarkers in the Down syndrome–Alzheimer’s disease continuum

These findings highlight the complementary roles of CSF and plasma tau biomarkers in tracking disease progression: CSF biomarkers capture early pathological changes, whereas plasma biomarkers more effectively reflect disease progression within symptomatic stages.
