Modulation of Non‐Rhythmic Temporal Prediction by Subthalamic Nucleus Deep Brain Stimulation (STN‐DBS) in Parkinson's Disease

Movement Disorders, Volume 41, Issue 4, Page 992-1003, April 2026.
Background Accurate temporal prediction, essential for adaptive motor behavior, relies on corticobasal ganglia circuits. In Parkinson's disease (PD), both motor and non‐motor functions are impaired. Deep brain stimulation (DBS) of the subthalamic nucleus (STN) effectively alleviates motor symptoms, but its effects on non‐motor domains, like temporal ...

Exploring small‐world brain connectivity in aging and its relationship with cognitive reserve

Alzheimer's &Dementia: Translational Research &Clinical Interventions, Volume 12, Issue 2, April/June 2026.
Abstract INTRODUCTION The aging brain's vulnerability to decline emphasizes the importance of strategies preserving cognitive function and independence. As age‐related brain changes do not always match clinical symptoms, reserve, encompassing brain reserve (BR) and cognitive reserve (CR), has emerged as a key mechanism supporting resilience and ...

Vagus nerve stimulation alters task‐evoked pupillary responses in older but not younger adults: A single‐blind active sham‐controlled crossover trial

Alzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION The locus coeruleus (LC) undergoes age‐related changes and is involved in Alzheimer's disease pathogenesis. Vagus nerve stimulation (VNS) may modulate LC activity and could be used therapeutically, but age‐related differences in VNS responses remain unexplored.

Adaptive Channel-Tracking Method and Equalization for MC-CDMA Systems over Rapidly Fading Channel under Colored Noise

EURASIP Journal on Advances in Signal Processing, 2010
A recursive maximum-likelihood (RML) algorithm for channel estimation under rapidly fading channel and colored noise in a multicarrier code-division multiple-access (MC-CDMA) system is proposed in this paper. A moving-average model with exogenous input (

The Four‐Square Step Test With and Without Dual Tasks Among Older Adults With and Without a Fall History: A Retrospective Cohort Study

Health Science Reports, Volume 9, Issue 2, February 2026.
ABSTRACT Background and Aim As the global population of adults aged 65 and older increases, so does the prevalence of falls, which are the second leading cause of unintentional injury deaths worldwide, according to the World Health Organization. The Four‐Square Step Test (FSST) is a widely used tool for assessing dynamic balance and mobility.

Long‐Term Effect of Acetylcholinesterase Inhibitors on Behavioral and Psychological Symptoms of Dementia

International Journal of Geriatric Psychiatry, Volume 41, Issue 1, January 2026.
ABSTRACT Objective Behavioral and psychological symptoms of dementia (BPSD) are critical aspects of the clinical presentation of dementia. There is no universally accepted approach for the managment of BPSD, currently based first on a non‐pharmacological and subsequently on a pharmacological approach.
