PMID: 39935389
Introduction: We investigated the association between alpha-synuclein (α-syn) pathology and brain glucose metabolism across the cognitive spectrum of Alzheimer's disease (AD) co-pathologies. Methods: Fluorodeoxyglucose positron emission tomography (FDG-PET) data from...

21(2):e14351.
PMID: 39868511
Introduction: We aimed to compare gait between individuals with Alzheimer's disease (AD), dementia with Lewy bodies (DLB), and cognitively unimpaired (CU) individuals and to evaluate the association between gait and...

Commun Med (Lond)
. 2025 Jan;
5(1):19.
PMID: 39820537
Background: Declining gait performance is seen in aging individuals, due to neural and systemic factors. Plasma biomarkers provide an accessible way to assess evolving brain changes; non-specific neurodegeneration (NfL, GFAP)...
