Structural Nonparametric Cointegrating Regression [PDF]

Nonparametric estimation of a structural cointegrating regression model is studied. As in the standard linear cointegrating regression model, the regressor and the dependent variable are jointly dependent and contemporaneously correlated.

Anatomical Associations Between Focal Mitochondrial Metabolism and Patterns of Neurodegeneration in Amyotrophic Lateral Sclerosis

Annals of Neurology, EarlyView.
Objective Amyotrophic lateral sclerosis (ALS) has a very specific neuroimaging signature, but the molecular underpinnings of the strikingly selective anatomic involvement have not elucidated to date. Accordingly, a large neuroimaging study was conducted with 258 participants to evaluate associations between patterns of neurodegeneration and focal ...

Nonparametric serial interval estimation with uniform mixtures.

PLoS Computational Biology
The serial interval of an infectious disease is a key instrument to understand transmission dynamics. Estimation of the serial interval distribution from illness onset data extracted from transmission pairs is challenging due to the presence of censoring

Non Parametric Instrumental Regression [PDF]

The focus of the paper is the nonparametric estimation of an instrumental regression function ϕ defined by conditional moment restrictions stemming from a structural econometric model: E [Y − ϕ (Z) | W] = 0, and involving endogenous variables Y and Z and

Serum p‐tau217 Is a Prognostic Indicator of Cognitive Impairment in Idiopathic REM Sleep Behavior Disorder

Annals of Neurology, EarlyView.
Objective Assess the performance of serum phosphorylated tau 217 (p‐tau217) and neurofilament light chain (NfL) in predicting risk of cognitive impairment or phenoconversion to dementia in individuals with iRBD. Methods We measured serum p‐tau217 and NfL levels by electrochemiluminescence across 4 polysomnographically confirmed iRBD cohorts (n = 300 ...

Refining Detection of Subclinical Epileptiform Activity in Alzheimer's Disease: A Case–Control Study and Call for a Consensus

Annals of Neurology, EarlyView.
Objective Sleep‐predominant network hyperexcitability is increasingly recognized as a potential disease‐accelerating comorbidity in Alzheimer's disease (AD). However, its prevalence and risk‐factors remain debated, largely due to cohort‐specific and methodological differences across studies.

Clinical and Biological Determinants of Longitudinal Cognitive Function in Patients With GBA1 Variants and Subthalamic Deep Brain Stimulation

Annals of Neurology, EarlyView.
Objective Whether cognitive decline in patients with Parkinson's disease (PD) carrying GBA1 variants is accelerated after subthalamic deep brain stimulation (STN‐DBS) remains controversial. Clarifying long‐term cognitive outcomes is essential for informed decision making.
