Brain and cognitive correlates of social status across race/ethnicity and sex/gender. [PDF]

Alzheimers Dement
Abstract INTRODUCTION Subjective social status (SSS) in the United States relates to cognition. Few studies assess SSS in one's community, examine brain correlates, or consider associations across the intersection of sex/gender and race/ethnicity. METHODS A total of 867 participants from the Washington Heights‐Inwood Columbia Aging Project completed ...

Cholinergic basal forebrain atrophy in Parkinson's disease with freezing of gait. [PDF]

Ann Clin Transl Neurol, 2023
Abstract Background Mounting research support that cholinergic dysfunction plays a prominent role in freezing of gait (FOG), which commonly occurs in Parkinson's disease (PD). Basal forebrain (BF), especially the cholinergic nuclei 4 (Ch4), provides the primary source of the brain cholinergic input.

Microstructural Characterization of Short Association Fibers Related to Long-Range White Matter Tracts in Normative Development. [PDF]

Hum Brain Mapp
This study investigates superficial white matter using advanced quantitative diffusion tractography. This paper addresses three key objectives: (1) mapping short association fibers in relation to long‐range white matter tracts, (2) characterizing typical neurodevelopmental changes, and (3) investigating the relationship between microstructural changes ...

Tau mediates the impact of amyloid and vascular disease burden on the trajectory of clinical symptoms. [PDF]

Alzheimers Dement
Abstract INTRODUCTION Amyloid (A) and vascular (V) pathologies often co‐occur and progress over decades. We leveraged chronicity, defined as the years above a biomarker‐positivity threshold, to examine how the timing of A and V relates to cognitive decline.
