Locus coeruleus‐entorhinal cortex tract integrity is linked to plasma tau and glial fibrillary acidic protein

open access: yesAlzheimer's &Dementia, Volume 21, Issue 12, December 2025.
Abstract INTRODUCTION Pretangle tau inclusions from the locus coeruleus (LC) are hypothesized to propagate to the entorhinal cortex (EC) via neuron‐to‐neuron transmission along its projections. The lower integrity of the LC‐EC pathway accompanying Alzheimer's disease (AD) pathology is supported by post mortem studies, but in vivo evidence remains ...

Detection of TDP‐43 seeds in CSF of presymptomatic and symptomatic genetic FTD/ALS

open access: yesAlzheimer's &Dementia, Volume 21, Issue 12, December 2025.
Abstract INTRODUCTION Seed amplification assays (SAAs) have shown promising results in detecting misfolded transactive response (TAR) DNA‐binding protein 43 (TDP‐43) in cerebrospinal fluid (CSF) of genetic frontotemporal dementia (FTD). To date, the use of SAA has yet to be evaluated in presymptomatic individuals.

Beta Power Response After Levodopa Intake in Parkinson's Disease Patients With Chronic Sensing‐Enabled Deep Brain Stimulation

open access: yesAnnals of Neurology, Volume 98, Issue 6, Page 1352-1363, December 2025.
Objective In Parkinson's disease (PD), the power of beta oscillations (± 13–30 hertz [Hz]) from subthalamic nucleus (STN) local field potentials (LFPs) is associated with motor symptoms. Beta power can be used for adaptive deep brain stimulation (aDBS) algorithms based upon symptom fluctuations.

Cerebrospinal fluid proteomic associations of APOE genotypes reveal distinct protective and risk mechanisms for Alzheimer's disease

open access: yesAlzheimer's &Dementia, Volume 21, Issue 10, October 2025.
Abstract BACKGROUND The apolipoprotein E (APOE) gene includes the strongest protective (ε2) and risk (ε4) variants for sporadic Alzheimer's disease (AD), but underlying mechanisms remain unclear. We studied APOE genotype effects on the cerebrospinal fluid (CSF) proteome.
