Speech Biomarkers From Smartphone Calls Track Progression in REM Sleep Behavior Disorder and Parkinson's Disease

open access: yesAnnals of Neurology, EarlyView.
Objective This 24‐month longitudinal study involving isolated rapid eye movement sleep behavior disorder (iRBD), early‐stage Parkinson's disease (PD), and matched healthy control subjects aimed to assess whether acoustic speech features from real‐world smartphone calls provide passive progressive biomarkers in synucleinopathies.

Brain Atrophy Associated With Risk Variant rs10191329 Extends Beyond Multiple Sclerosis

open access: yesAnnals of Neurology, EarlyView.
The risk allele rs10191329*A is associated with disease severity and brain atrophy in people with multiple sclerosis (MS). We investigated the association of rs10191329 with age‐related brain atrophy in a population‐based cohort using 10,308 magnetic resonance imaging (MRI) scans of 4,815 participants aged ≥ 45 years without MS in cross‐sectional and ...

When Does Alzheimer's Disease Start? Plasma Aβ42/40 Assays Show Steep Changes at Aβ‐PET Centiloid 15, Mean Age of 66 Years

open access: yesAnnals of Neurology, EarlyView.
Objective Sporadic late‐onset Alzheimer's disease (AD) is characterized by a long pre‐clinical phase where amyloid‐beta (Aβ) and tau begin to accumulate in the brain. The primary objective was to determine the age at which AD starts by finding the average population age when both positron emission tomography (PET) Aβ (Aβ‐PET) and plasma Aβ42/40 become ...

Tau Pathology in Alzheimer's Disease Uniquely Affects Sulcal Depths

open access: yesAnnals of Neurology, EarlyView.
Objective Though it is widely known that tau deposition affects brain structure, the precise localization of these effects is poorly understood, especially in relation to gyral and sulcal anatomy. We investigated whether tau pathology in Alzheimer's disease (AD) preferentially affects sulci, and particularly sulcal depths.

Individualized Atrophy‐Based Prediction of Dementia Progression in Familial Frontotemporal Lobar Degeneration With Bayesian Linear Mixed‐Effects Modeling

open access: yesAnnals of Neurology, EarlyView.
Objective Age of symptom onset is highly variable in familial frontotemporal lobar degeneration (f‐FTLD). Accurate prediction of onset would inform clinical management and trial enrollment. Prior studies indicate that individualized maps of brain atrophy can predict conversion to dementia in f‐FTLD.

Simultaneous Imaging of Cu+ and Cu2+ in Neural Cells Using DNAzyme Probes Reveals Mechanistic Link Between Copper Redox Imbalance and Amyloid Pathology

open access: yesAngewandte Chemie, EarlyView.
We develop Cu+‐ and Cu2+‐specific DNAzyme fluorescent probes to visualize both copper redox states in living neurons. Aβ oligomers cause intracellular copper overload, triggering FDX1 dependent cuproptosis and generating ROS. This work links copper redox imbalance with Aβ pathology and offers a selective, sensitive way to monitor copper homeostasis in ...

Sex‐Specific Genetic Architecture of ALS: Evidence of a Female Protective Effect?

open access: yesAnnals of Neurology, EarlyView.
Background Amyotrophic lateral sclerosis (ALS) shows sex differences in incidence and age of onset, yet the underlying biological mechanisms remain poorly understood. Methods We investigated sex‐specific genetic architecture in an Italian ALS cohort with whole‐genome sequencing (1,333 ALS cases, 755 controls).
