Hand dexterity, not handgrip strength, is associated with executive function in Japanese community-dwelling older adults: a cross-sectional study

An association between handgrip strength, hand dexterity and global cognition is suggested; however, it unclear whether both motor functions are associated with executive function, which important for performing daily activities. Understanding this will help identify risk factors impairment of function in late adulthood. We aim to investigate the relationship strength physically mentally healthy community-dwelling older adults.Three hundred twenty-six adults (287 women, mean age ± SD, 70.1 5.6) underwent tests using a dynamometer Purdue Pegboard Test (PPT), respectively. Executive was evaluated Trail Making (TMT)-A, TMT-B Digit symbol; assessed Mini-Mental State Examination (MMSE).Age-group differences showed that younger groups (60-64, 65-69 70-74) had significant better PPT performance than oldest group (75 older), whereas no were observed strength. Multiple regression analysis adjusted potential covariates, including MMSE scores, TMT-A, TMT-B, symbol significantly scores; variables strength.Hand vulnerable effects aging and, contrary strongly associates independent cognition. Our results suggest assessing may individuals at higher among high-functioning adults.

Decreased upper-extremity/visuomotor abilities are frequently encountered in healthy aging. However, few studies have assessed hand movements the prodromal stage of dementia. The evaluation visuomotor skills patients with Mild Cognitive Impairment (PwMCI) may non-negligible clinical relevance both diagnostic and prognostic terms, given strong relationships executive functioning functional autonomies. In present review paper, these issues will be disclosed by describing general pathophysiological neuropsychological mechanisms responsible for deficits, reporting available experimental results on differences between PwMCI, controls and/or Moreover, binding domains to autonomies then addressed. Finally, we propose insights future research.

The relationship between manual dexterity and cognitive function among older adults is well known; however, few studies have focused on training that confirms load of in through functional near-infrared spectroscopy (fNIRS) verifies the effect training. This study examined effects home-based using a digital trail-making peg test device combining two conventional assessment tools namely, tests.For 12 weeks, 57 healthy aged 65-88 years participated parallel-group, randomized controlled trial, wherein was performed for approximately 20 min daily. To quantify different conditions, we assessed cortical activation patterns prefrontal cortex via wearable four-channel fNIRS device.

VR Cognitive-based Intervention for Enhancing Cognitive Functions and Well-being in Older Adults with Mild Cognitive Impairment: Behavioral and EEG Evidence

Psychosocial Intervention, Год журнала: 2025, Номер 34(1), С. 37 - 51

Опубликована: Янв. 1, 2025

Objective: Mild cognitive impairment (MCI) has been recognized as a window of opportunity for therapeutic and preventive measures to slow decline. The current study investigated the efficacy virtual reality (VR) cognitive-based intervention on verbal visuospatial short-term memory (STM), executive functions (EFs), wellbeing among older adults with without MCI. Method: immersive VR comprised eight 60-minute sessions, held twice week over span 30 days. participants consisted 31 non-MCI in experimental group (mean age ± SD = 66.31 3.12 years), 29 MCI 68.19 5.03 control 64.97 3.35 years). dependent variables were assessed by using battery computerized test, well-being people questionnaire resting-state EEG. A repeated-measures ANCOVA was employed examine effects developed intervention. Results: Significant improvements observed both STMs EFs following intervention, indicated behavioral EEG findings, ranging from small large effect sizes (i.e., .05-.17).

People with Long Covid and ME/CFS Exhibit Similarly Impaired Dexterity and Bimanual Coordination: A Case-Case-Control Study

The American Journal of Medicine, Год журнала: 2024, Номер unknown

Опубликована: Фев. 1, 2024

Abstract

Purpose

Dexterity and bimanual coordination had not previously been compared between people with long COVID Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). Therefore, this study determined dexterity in (∼16 month illness duration; n=21) ME/CFS year n=20), versus age-matched healthy controls (n=20).

Methods

Dexterity, was using the Purdue pegboard test.

Results

The main findings of present investigation were that generally comparable for tests (p>0.556 d<0.36 pairwise comparisons). It is worth noting however, both these patient groups performed poorer Perdue test than (p<0.169 d>0.40

Conclusions

These data suggest have similarly impaired dexterity, coordination. there an urgent need interventions to target ME/CFS, given current pandemic, COVID.

Manual dexterity in young and healthy older adults. 1. Age‐ and gender‐related differences in unimanual and bimanual performance

Developmental Psychobiology, Год журнала: 2018, Номер 60(4), С. 407 - 427

Опубликована: Март 12, 2018

This study aimed to better characterize age-related differences in dexterity by using an integrative approach where movement times and kinematics were measured for both hands. Forty-five young (age 19-31) 55 healthy older adults 60-88) evaluated during unimanual bimanual performance of the Purdue Pegboard Test. Gender effects also assessed. From video-recorded data, obtained reaching, grasping, transport, inserting. Results showed that had longer grasping inserting with right hand, across all movements left hand. Kinematic found path length, linear, angular velocity. The patterns slowing similar tasks. more males than females. Age not only comprise but kinematic alterations. importance gender hand function was demonstrated.

White Matter Microstructural Correlates of Cognitive and Motor Functioning Revealed via Multimodal Multivariate Analysis

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2024, Номер unknown

Опубликована: Июнь 8, 2024

1. Abstract Recent advances in cognitive neuroscience emphasise the importance of healthy white matter (WM) optimal behavioural functioning. It is now widely accepted that brain connectivity via WM contributes to emergence behaviour. However, association between microstructure fibres and behaviour poorly understood. This part due indirect overlapping methods assessing microstructure, use overly simplistic approaches Here, we used Mahalanobis Distance (D2) integrate 10 metrics derived from multimodal neuroimaging have strong ties microstructure. The D2 metric was chosen because it accounts for metrics’ covariance as measures voxelwise distance every subject average; thus providing a robust multiparametric assessment To examine WM-behaviour associations, multivariate correlation correlates 2 motor tasks, which allowed us compare within across domains WM. We observed organised cognitive, motor, integrative variables are widespread their associations with WM, frontal parietal regions. Our results highlight complex nature behaviour, show need modelling when examining brain-behaviour associations.
