The Training Effects of Tinkering Activities on Cognitive Flexibility in Older Adults From Communities

Aging has been a serious global-wise concern in public health. In particular, elders face declination of cognitive functions that threaten their quality of life. A good approach to slow down cognitive declination during aging processes is therefore in urgent need. According to the Successful Aging model (Rowe, J.W. and Kahn, R.L) participation in meaningful occupational activity may maintains high cognitive and body function. This sub-project is a part of the larger integrated project that will address the need for cognitive promotion by conducting cognitive training interventions on community older adults, utilizing the National Taiwan Science Education Center (NTSEC) as the public recruiting site as well as intervention site. In this sub-project, a 12-week intervention will be carried out with three protocols: 1) Tinkering activities, 2)Controlled Tinkering Activities, and 3) Board Game intervention. Board games serve as a commonly seen cognitive training, with a growing series of literature continuing to support board games being the medium of cognitive promotion. Tinkering activities are primarily used in fields of education that comprise science, art, and technology. Through a series of themes objectives, participants can involve interestingly, creatively, and flexibly in the activity when the participants fulfill the goal with the materials retrievable at the site. The anticipation is that the elders participating in Tinkering activities may increase their cognitive flexibility as the participants involve in the elements hidden within the core of the training, such as problem exploration, active thinking and inference, trial and error, and problem-solving. The investigators target to obtain pre-and post-intervention behavioral and neurophysiological data, including electroencephalogram data in 40 experimental participants, 40 active control participants, and 40 passive control participants over a period of 3 years.

Xbox-Based Exergames Versus Structured Home-Based Cognitive Training for Attention and Executive Functions in Healthy Adults

Background: Exergames are increasingly used to support cognition in older adults; however, evidence comparing exergames with non-computerized cognitive training in healthy adults remains limited. Objective: This randomized controlled trial aimed to compare the effects of Xbox-based exergames and structured home-based cognitive training on attention and executive functions in healthy adults. Methods: Twenty healthy adults aged ≥50 years were randomly allocated to either an Xbox-based exergames group (n=10) or a structured home-based cognitive training group (n=10). Both groups received 12 sessions twice weekly. Before and after the intervention, participants were assessed using the Standardized Mini-Mental State Examination, d2 Test of Attention, Stroop Test, WMS-R Digit Span Test, Trail Making Test, and Benton Judgment of Line Orientation Test.

Brain Research and Integrative Neuroscience Network for COVID-19

The aim of the experimental study is to investigate two interventions for the management of cognitive symptoms resulting from long COVID. Participants will be randomly assigned into two interventions. 1. Categorization Program (CP) training with active tDCS or 2. Categorization Program training with sham tDCS.

Personalized Sensory Stimulation: Urban and Rural Dementia Care

As Taiwan transitions into a super-aged society, rising dementia rates have severely strained long-term care systems. Although current daycare centers provide multi-modal programs, they remain limited to behavioral training, lacking precise interventions targeting brain function and neuroplasticity or integrated non-invasive neuromodulation technologies. Furthermore, urban-rural disparities in resources, staffing allocation, and tech experience hinder practical deployment, with empirical research remaining scarce. Addressing this gap, this study investigates a smart brain health promotion model combining personalized gamma music stimulation and cognitive training for mild cognitive impairment and dementia, while evaluating its feasibility across diverse care settings.

Effects of Adaptive Difficulty Computerized Cognitive Training on Cognitive Function Improvement in Older Adults With Mild Cognitive Impairment

This study aims to evaluate the effectiveness of adaptive computerized cognitive training (CCT) in improving cognitive function among community-dwelling older adults with mild cognitive impairment (MCI) and to compare the maintenance effects of different training frequencies after the initial intervention. A quasi-experimental study will be conducted in three communities in Shenyang, Liaoning Province, China. All participants will receive a 12-week adaptive CCT program. Participants will be assigned to either a high-frequency maintenance training group or a training discontinuation group. Cognitive assessments will be performed at baseline, immediately after the intervention, and during follow-up. The primary outcome is global cognitive function, while secondary outcomes include memory, attention, executive function, language, visuospatial ability, and activities of daily living. The findings of this study are expected to provide evidence for optimizing computerized cognitive training programs and long-term management strategies for older adults with MCI in community settings.

Cognitive Training and Neuroplasticity in Mild Cognitive Impairment: COGIT-2 Trial

Effective, clinically meaningful treatments are lacking for patients with mild cognitive impairment (MCI), which is associated with increased risk of transition to dementia. Cognitive training represents an important therapeutic strategy. In a previous study, crossword puzzles were found to be superior to computerized cognitive training on the primary cognitive outcome and function with decreased brain atrophy. Building on these findings, this study will evaluate and compare the impact of high dose crosswords (4 puzzles per week) to low dose crosswords (1 puzzle per week) and a health education control group on the cognition and function of participants.

Music Improvisation Training on Cognitive Function in Older Adults

This project will study the effects and mechanisms of a music improvisation training intervention on self-regulation of older adults with and without MCI. The investigator's overall hypothesis is that improvisation training will lead to improvements in self-regulation, compared to controls, and that improvisation training will be associated with specific changes in prefrontal brain networks and ultimately cognitive engagement.

The Targeted Neurocognitive Training (TNT) Study

People with HIV (PWH) often suffer from cognitive impairments known as HIV-Associated Neurocognitive Disorder (HAND). Cognitive impairments in PWH are not fully captured by traditional neurocognitive assessment; thus, we must examine cognitive performance both within a task (inconsistency) and across cognitive domains (dispersion), called Intra-Individual Variability (IIV). IIV predicts cognitive impairment/decline, altered brain morphology, and neuropathology in many clinical populations. Conceptually, IIV results from "executive dyscontrol" or the efficiency (or inefficiency) with which executive control processes coordinate other cognitive processes/domains. Based on the Executive Dyscontrol Hypothesis and underlying calculations of IIV, one way to improve cognition in PWH is through interventions that target improvements in their most severely impaired cognitive domains. We hypothesize such improvements, in turn, should reduce the strain placed on executive functioning resources, freeing up resources needed to compensate for impairments in any domain and, in turn, reducing IIV. Computerized cognitive training, widely used in the study team's prior work, is ideally suited to target impairments in select cognitive domains using computerized cognitive training. In our systematic review of 13 cognitive training studies in PWH, we found cognitive training improved performance in the targeted domain. In this feasibility study, we will assess 150 PWH at baseline with the expectation to recruit 120 PWH with HAND. Then we will use a two-group pre-post experimental design of 120 adults with HAND including: 1) a Targeted Neurocognitive Training (TNT) group (n=60) to train each participant's two most impaired cognitive domains (e.g., attention \& memory) assessed from a neurocognitive battery at baseline, and 2) a no-contact control group (n=60). Aim 1 - Feasibility: To determine feasibility and acceptability of the intervention. Exploratory Aim 1 - Cognition: Compare adults who receive TNT to those who receive no training to determine whether they improve on the cognitive domains trained, show less cognitive IIV across domains and within a task, and demonstrate improved executive functioning. Exploratory Hypothesis 1: TNT will improve cognitive functioning in the targeted impaired cognitive domains. Exploratory Hypothesis 2: TNT will reduce cognitive IIV (both overall dispersion \& inconsistency). Exploratory Hypothesis 3: TNT will improve executive functioning. Exploratory Hypothesis 4: TNT will improve global cognition and reduce HAND severity. Innovation 1 - This is the first study to use IIV to guide cognitive training to target the most impaired cognitive domains to reduce cognitive IIV in HIV. Innovation 2 - This will be one of the first studies to prospectively include both types of cognitive IIV - dispersion and inconsistency - allowing us to examine the relationship between dispersion and inconsistency. Innovation 3 - The epicenter of HIV is in the Deep South where this study will occur.

Executive Functioning Training Study

Cognitive aging in people with HIV (PWH) is of increasing concern for several reasons: 1) between 52%-59% of PWH experience cognitive impairment known as HIV-Associated Neurocognitive Disorder (HAND) which impacts everyday functioning and quality of life; 2) HAND increases in severity and prevalence with age; and 3) 70% of PWH in the United States will be 50 and older by 2030. Fortunately, cognitive training programs can individually target specific cognitive impairments in PWH and possibly reduce the severity and prevalence of HAND and improve everyday functioning and quality of life. This approach is based around the underlying concept of intra-individual variability as controlled through higher level allocation of cognitive resources, known as executive functioning. This feasibility study will use a two-group pre-post experimental design of adults with HAND including: 1) a 20-hours of Executive Functioning Training group (enroll 60, n=48 with attrition), and 2) a no-contact control (enroll 60, n=48 with attrition). Aim 1 - Feasibility: To determine feasibility and acceptability of the intervention (i.e., attrition, feedback). Exploratory Aim 1 - Cognition: Compare adults who receive Executive Functioning Training to those who receive no training to determine whether they improve in global cognitive ability and overall cognitive IIV. This high impact study is innovative in the following ways: 1) This is the first study aimed to reduce cognitive IIV in PWH. 2) This is the first study to use IIV as a guide to target solely executive functioning training to improve global cognitive ability, which may reduce the severity and prevalence of HAND. 3) Over the last decade, the epicenter of HIV has emerged in the Deep South where this study will occur. Most participants in this study will be older PWH who identify as lower social economic status (SES) and/or African Americans and experience HAND symptoms.

Spatial Cognitive Training for Chronic Vestibular Disorders

In this study the investigators propose to apply cognitive training, which has been largely used in the realm of age-related cognitive decline, dementia, and Alzheimer's disease, in a novel clinical context to individuals with vestibular impairment. In prior work the investigators observed that individuals with vestibular loss have evidence of spatial cognitive impairment. The investigators plan to evaluate the preliminary efficacy and feasibility of a cognitive training program in a sample of participants with chronic vestibular impairment who display deficits in spatial ability. The cognitive training program will focus on visuospatial skills and will be used as an adjunct to traditional vestibular physical therapy (VPT).

Multidomain Interventions for Elderly Individuals in Residential Structures

The "Multidomain Interventions to improve the COgnitive and fUNctional well-being of elderly individuals in residential sTructures" (I-COUNT) study aims to test the feasibility and the effectiveness of a multidisciplinary intervention among elderly individuals living in long term care facilities (LTCFs). The intervention will include selected physical and cognitive training activities administered and monitored by new technologies, a dietary intervention including also functional foods, and the administration of vaccines according to the National plan. The multidomain intervention will last 6 months and will be compared with the standard care adopted in the same LTCFs.

Effect of Functional Core Stability Training or Cognitive Training on Balance and Postural Control in Chronic Ankle Instability

The purpose of the study is to investigate dynamic core stability training versus cognitive training on balance, functional performance, postural control, ankle instability scores, ankle dorsiflexion range of motion, and mental workload in chronic ankle instability

Promoting Inclusive Education Through Executive Functions

Background: Recently governments worldwide have been doing enormous efforts to ensuring egalitarian educational opportunities for all children. However, the number of children that remain out of the school or lack proficiency in academic performance is still very worrying. One of the factors that seems to contribute to such inequalities is socioeconomic status (SES). SES strongly impacts the developmental trajectory of both the brain and cognitive abilities as off early childhood, further affecting learning and academic success. Despite the great interest in building inclusive societies and the promising results of executive functions' training programs for leveling the SES-achievement disparities, only a few studies have actually included schools from low-SES settings and lack a comprehensive, evidence-based background underlying the intervention protocols. Thus, with a preventive emphasis, the current project aims to implementing and evaluating a cost-effective game-based training protocol to promote and boost the development of executive functions in preschool and elementary school-aged children from disadvantaged contexts, ultimately contributing to prevent school dropout and reduce academic inequalities.

Effects of Cognitive Training on Chemotherapy-Induced Cognitive Impairment in Colon Cancer Patients Undergoing Treatment(Chemobrain) in Oncology Patients With Colon Cancer Undergoing Active Treatment

Introduction: With the increasing survival rate in colon cancer, as a result of technological and biomedical advancements, it is essential to thoroughly study the secondary symptoms related to the oncological disease process. One of the most common and underestimated symptoms is cancer-related cognitive impairment (CRCI). Objective: To evaluate the efficacy of a cognitive training program in controlling CRCI in individuals with colon cancer undergoing active treatment. Methodology: A randomized controlled clinical trial with two parallel groups: an intervention group (IG) and a control group (CG). The study population will include individuals newly diagnosed with colon cancer. A sample size of 50 participants has been estimated, with 25 in each group, to detect a difference of 2.95 points or more in the MoCA cognitive impairment questionnaire. All participants will receive an educational leaflet based on the new WHO guidelines, which recommend specific measures to reduce the risk of cognitive impairment. In addition to receiving this informational leaflet, the IG will participate in a cognitive training program (CT) focused on everyday cognition (EC) individually. Each participant will receive a dossier with 80 intervention sessions divided into four training periods (P1-P4), each containing 20 activities. Each period will last for one month. Baseline and 4-month post-intervention evaluations will be conducted for both groups, measuring sociodemographic and clinical variables, as well as study-related cognitive impairment variables: Cognitive function (MoCA test), Everyday Cognition (PECC), Anxiety (Hamilton), Functionality (LB), Sleep Quality (PSQI), Quality of Life (ECOG), and Subjective Memory Complaints (FACT-COG). Impact: The results of this study could lead to the design of specific cognitive interventions and the establishment of protocols for colon cancer patients undergoing active treatment, helping them manage one of the most underestimated symptoms in this patient population-CRCI-whose incidence is increasing due to the improved survival rates in this disease.
