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

Annals 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.

Cortical thickness subtypes in cognitively unimpaired individuals: Differential network and transcriptomic vulnerability to cortical thinning

Alzheimer's &Dementia, Volume 21, Issue 10, October 2025.
Abstract INTRODUCTION The emergence, stability, and contributing factors of Alzheimer's disease (AD) gray matter subtypes remain unclear. METHODS We analyzed data from 1323 individuals without a diagnosis of dementia (CDR < 1) with T1w‐MRI and amyloid‐PET, including 622 with longitudinal data (3.66 ± 1.78 years).

Understanding barriers and optimizing socio‐cognitive assessment in the diagnosis of neurocognitive disorders

Journal of Neuropsychology, Volume 19, Issue 3, Page 603-618, September 2025.
Abstract Harmonized neuropsychological assessment for neurocognitive disorders (NCDs) is an urgent priority in clinics. Neuropsychology assessments in NCDs seldom include tests exploring social cognitive skills. In 2022, we launched the SIGNATURE initiative to optimize socio‐cognitive assessment in NCDs.
