The Impact 360 study will evaluate the effects of a combined intervention of exercise, mindfulness, and nutrition on 8 key indicators of health and the mechanisms that drive these changes. 60 subjects aged 50 to 75 without a current diagnosis of a brain disorder will be recruited. This study will follow a partial crossover design. All participants will receive the intervention. Participants randomized into the intervention group after their baseline screening will receive the 6-month intervention. Those randomized into the waitlist group will complete another assessment at the end of the 6-month care as usual phase before receiving the intervention.

The number of older Americans will double in the next 4 decades to nearly 90 million, placing an unprecedented financial and resource burden on the health care system. Exercise has clear and demonstrable physical benefits, but a more precise understanding of how exercise supports cognitive function is essential. Demonstrating definitively that exercise as recommended by public health entities has benefits for cognition would have enormous public health implications, encourage the public to adapt more active lifestyles, and stimulate the development of effective exercise delivery programs.

This multicenter, cross-sectional observational study aims to use precision nutrition tools to identify metabolic clusters in adults aged 50-75 years, enabling tailored nutritional and protein recommendations based on specific metabolic characteristics. Conducted at Eurecat-Reus (Catalonia) and AZTI (Bizkaia), the study will enroll 200 participants (75 at Eurecat, 125 at AZTI). Analyses will include metabolomics, gut microbiota profiling, epigenomics, and glycomics, with the goal of refining dietary guidelines and protein intake recommendations to address the specific needs of aging populations.
NCT06491264
With an aging population worldwide, it is critical to develop effective interventions promoting healthy cognitive aging. Transcranial electrical stimulation (tES) is a promising but not fully realized noninvasive brain stimulation approach that could improve memory. This study investigates the behavioral and electrocortical effects of personalized tES in aging to determine whether whether optimal dosing, electrode placements, and waveforms elicit stronger responses.

Taiwan is entering a super-aged society in 2025, with more than 20% of the population aged 65 years or older. This rapid demographic shift, combined with increasing rates of chronic diseases, frailty, and dementia, has created growing challenges for healthcare and caregiving systems. Yunlin County, particularly its coastal region, has been one of Taiwan's earliest super-aged areas, showing higher rates of diabetes (10.5%), hypertension (28%), hyperlipidemia (26%), dementia (8%), and depression (12%) compared with national averages. Lifestyle factors such as tobacco (30%), betel nut (8%), and alcohol (15%) use are also more prevalent among local residents. From 2022 to 2024, health screenings at CMU Beigang Hospital revealed a 36.1% abnormality rate among 12,222 visits, while another 5,965 assessments from the county's ICOPE program showed similarly high rates. Many older adults, particularly retired agricultural and fishing workers, experience sedentary lifestyles and polypharmacy-related risks, which worsen frailty, insomnia, depression, and cognitive decline. Low general and digital health literacy further limits their ability to adopt preventive behaviors, forming a vicious cycle between poor health and aging. To address these challenges, the Ministry of Health and Welfare launched the "Healthy Taiwan Cultivation Plan." In alignment with this initiative, this project-led by CMU Beigang Hospital in collaboration with the National Health Research Institutes-aims to develop a wearable- and mobile-based health promotion model for rural older adults. The study will integrate research-grade actigraphy (Geneactiv), a mobile health platform ("iMED"), and the in-bed sensor iCue to monitor behavior, promote active aging, and enhance health and digital literacy. Ultimately, this project seeks to establish Taiwan's first integrated digital aging database and identify digital biomarkers for predicting cognitive and functional decline in older adults.
NCT05847985
Lewy body diseases (LBDs) represents a group of neurodegenerative disorders characterized by the abnormal accumulation of aggregates of α-synuclein protein leading to the formation of Lewy bodies (LB) and Lewy neurites resulting in cell death. LBDs consists of two major clinical entities - Parkinson's disease (PD) and dementia with LB (DLB). Vast majority of patients with LBDs either already have mild cognitive impairment (MCI) at the time of the diagnosis or will develop it during the course of the disease. Language dysfunctions in LBDs patients with MCI are often unrecognized, which are difficult to treat, but even subtle changes might lead to impairment of social and occupational functioning with profound effect on their quality of lives. Current pharmacological or surgical strategies are effective for tackling the motor issues of LBDs with very limited effects on other symptoms such as language dysfunctions. Therefore, non-pharmacological approaches are gaining more attention. One of these non-pharmacological strategies is the use of noninvasive brain stimulation (NIBS) techniques that are able to modulate the brain functions with the effects on human nervous system plasticity. In this proposed project the investigators aim to first describe specific alterations in the language domain in LBDs patients with MCI as compared to healthy controls (HC) and identify the neural underpinnings of these changes using novel combination of advanced multimodal imaging techniques and various analytical methods. Secondly, the investigators aim to use NIBS as a supervised and individualized home-based therapeutical approach to tackle the language dysfunctions.

FAXAge is a randomized controlled trial investigating the effects of fasting and exercise on human aging. 240 participants over the age of 65 will be divided into 4 groups - an exercise group, a fasting group, a combined exercise and fasting group and a control group. The intervention will last for one year, and tests of biomarkers of aging will be performed at baseline, after 3 months, 6 months and at the end of the intervention. A reference group of participants over the age of 20 equally distributed by age and sex will be used to train an algorithm for determination of biological age. The study will include both physical, molecular and digital biomarkers including DNA-methylation, VO2max, body composition and face- and voice-age. The main outcome of the project is DNA-methylation age at week 52. Secondary outcomes are the rest of the tested biomarkers at week 52. It is hypothesised that the intervention groups will have similar superior benefits after the 52 weeks of intervention.
NCT07231783
This is a randomised, double-blind, placebo-controlled, parallel study to assess the effects of Urolithin A (Mitopure®) supplementation on muscle strength and performance in healthy middle-aged adults. Participants will be randomized to consume Mitopure® (500 mg), Mitopure® (1000 mg), or placebo once daily for 6 months.

The MESO7 study is a prospective observational research project designed to investigate the mechanisms of resilience and neurodegeneration in neurological diseases and healthy aging. It leverages advanced multiparametric brain and spinal cord imaging at high (3T) and ultra-high magnetic fields (7T) to assess structural, functional, metabolic, and mesoscale changes in the central nervous system (CNS). Particular emphasis is placed on sodium (23Na-MRI) and phosphorus (31P-MRI) imaging, along with layer-dependent brain connectivity analysis. The primary objective is to evaluate the impact of neuronal energy failure, measured via sodium concentration, on functional and structural reorganization in both healthy individuals and patients with various neurological conditions. Directed brain network models will be constructed from MRI data to quantify the connectivity strength (in- and out-degree) of cortical nodes. These connectivity metrics will be correlated with sodium concentrations to assess energy failure and its role in network reorganization. Longitudinal follow-up over two years is planned for subgroups with clinically progressive diseases. Secondary objectives include decoding metabolic, microstructural, and functional signatures of successful aging at the laminar level; characterizing disease-specific patterns of cortical and spinal microstructure associated with physical and cognitive dysfunction; describing longitudinal mesoscale and metabolic changes; and generating representative normative imaging datasets for the neuroscience community. The study plans to enroll a total of 540 patients across 9 neurological conditions:Multiple Sclerosis (MS), Neuromyelitis Optica Spectrum Disorders (NMOSD), MOG Antibody Disease (MOGAD), Alzheimer's disease, Parkinson's disease, Amyotrophic Lateral Sclerosis (ALS), temporal and non-temporal epilepsy, and mild traumatic brain injury (mTBI),in addition to 160 age- and sex-matched healthy controls, totaling 700 participants. Imaging and clinical assessments will be performed at the CEMEREM center at Timone University Hospital, AP-HM, Marseille, France. Each participant will undergo multiparametric brain and spinal cord MRI, including DTI, BOLD, MP2RAGE, SWI, quantitative sodium and phosphorus imaging, and functional assessments including neuropsychological testing, visual and motor function tests. Disease-specific assessments such as OCT, evoked potentials, and disability scores (e.g., EDSS for MS) will also be included when appropriate. The study is expected to improve understanding of CNS adaptation mechanisms and support the development of more accurate diagnostic and prognostic tools for neurodegenerative diseases

The purpose of the study is to investigate the influence of walking with external visual cues on brain adaptations.
NCT07151365
This prospective study investigates the health effects of vegetarian and plant-based diets in middle-aged and older adults in Taiwan, specifically, recruiting 5000 Tzu Chi volunteers. Previous Tzu Chi cohorts found vegetarian diets were protectively associated with incidences of diabetes, stroke, gout, cataracts, insomnia, and gallstones, while reducing healthcare costs. The study also aims to clarify dietary patterns-particularly plant-based and vegetarian diets-and determine how potential deficiencies or excesses of various nutrients influence common aging-related health issues, including healthy cognitive decline, sarcopenia, and the risk of age-related diseases, in order to inform dietary and lifestyle recommendations that promote healthy aging and maintain physical function.
NCT06343558
Rare and very rare neurological diseases primarily or exclusively affect the nervous system with a prevalence of \< 5 out of 10'000 and 100'000 people, respectively. Besides these, there are undiagnosed neurological diseases: neurological conditions without a diagnosis after completing a full diagnostic examination. Rare, very rare, and undiagnosed neurological diseases are complicated and progressive and often cause variegated motor signs, impairments, and syndromes. Balance and gait are frequently affected in these conditions, already at the clinical examination. These balance and gait impairments limit activities and cause an increased risk of falling. Falls can eventually result in injuries, even severe. There are only a few studies about these diseases, likely because of their rarity. Hence, the clinical presentation and the course of rare and very rare diseases are poorly known or even unknown. Essential information for these conditions' diagnosis, prognosis, treatment and rehabilitation is missing. MaNeNeND is an observational study underway at the Fondazione IRCCS Istituto Neurologico "Carlo Besta" (Milano) aimed at detailing the clinical and biological features of very rare and undiagnosed neurological diseases. Research questions: 1. Do patients with rare (Ra), very rare (V) and undiagnosed (U) neurological diseases suffer a balance and gait impairment? 2. Is there a correlation between the clinical and instrumental severity of the balance and gait impairment in RaVU neurological diseases? 3. Are instrumental measures more sensitive in detecting balance and gait impairments in patients affected by a RaVU neurological disease than the clinical measures? 4. Do the balance and gait impairments in RaVU neurological diseases worsen in time? The current project aims at diagnosing, quantifying and detailing the balance and gait impairment in rare, very rare and undiagnosed neurological diseases. To this aim, questionnaires, clinical scales and instrumental tests will be administered to these patients to collect a wide range of balance and gait measures. These measures will also integrate those collected with MaNeNeND to provide a more detailed description of patients with rare, very rare and diagnosed neurological diseases. Participants will complete two questionnaires: the Dizziness Handicap Inventory - short form (DHI-sf, an ordinal score of self-perceived balance) and the Modified Fatigue Impact Scale (MFIS, an ordinal score of self-perceived fatigue). Moreover, a clinician will administer the Mini Balance Evaluation Systems Test (Mini-BESTest, an ordinal score of balance), the 10 m walking test (for measuring the gait speed and other gait parameters) and the Timed Up and Go test (an instrumental measure of mobility and balance). Walking and the Timed Up and Go tests will be recorded with a trunk-worn inertial measurement unit. Finally, participants will be asked to complete an instrumental upright stance and gait assessment, the first consisting of standing on posturographic plates and the second of walking on a treadmill equipped with force sensors. When walking on the treadmill, an optoelectronic system will also record the position in time of limbs and trunk. The quantification of the severity of the balance and gait impairment of the patients suffering a rare, very rare or undiagnosed neurological disease will highlight these persons' therapeutic and rehabilitative needs. Comparing the balance and gait impairment of rare, very rare and undiagnosed diseases with those of multiple sclerosis, Parkinson's disease and peripheral neuropathy will highlight if the formers' balance and gait impairment has unique characteristics that could help ease the diagnosis of these uncommon conditions. The longitudinal measurements on rare, very rare and undiagnosed diseases will be paramount to identifying prognostic factors. In addition, the data collected in the current study will be crucial for future studies, for example, for estimating the sample size in clinical trials.

The aging population is growing rapidly. For the first time ever, Canadian seniors outnumbered young adults in 2016. Aging is associated with many physical and metabolic deteriorations including the loss of muscle mass and strength, insulin resistance, increased inflammation and oxidative stress. The muscles of our bodies are composed of proteins and proteins are made of small building blocks called amino acids. Our bodies have the ability to make some amino acids which are called the non-essential amino acids. However, there are certain amino acids that our body's need to make protein but can only be supplied from the foods that we consume. These are called essential amino acids. Tryptophan is one of the essential amino acids that the body needs. Tryptophan is required for protein synthesis and acts as a precursor for serotonin and nicotinic acid. Therefore, there may be a need for more threonine in the diet of older adults. However, the current requirement for threonine is based on studies conducted exclusively in young adults. Thus, the purpose of this study is to find out how much tryptophan older adults need.

The full experiment involves participants coming into the lab on five separate occasions for neuropsychological testing, a decision making battery, functional and structural MRI, and two TMS sessions for stimulation of the target or control stimulation site. The clinical trial component concerns only the last two sessions where subjects will be randomly assigned to different groups to receive different TMS interventions. In particular, the TMS experiments will ask two main questions: 1. What is the causal role of frontal pole in explore-exploit behavior in younger and older adults? 2. What is the causal role of IFG in explore-exploit behavior in younger and older adults? The investigators will use continuous theta-burst transcranial magnetic stimulation (cTBS, Huang et al. 2005) to inhibit neural activity in each region for approximately 50 minutes (Wischnewski \& Schutter, 2015) and measure the downstream effects on behavior in younger and older adults. Consistent with their respective roles in the explore-exploit circuit (Figure 5 in Research Strategy), the investigators predict that inhibition of frontal pole will lead to a selective reduction in directed, but not random, exploration, while inhibition of IFG will decrease exploitation and lead to increases in both types of exploration. Participants in each age group will be pseudo-randomly assigned to either the frontal pole group or IFG group such that the study will have 42 participants (21 males, 21 females) in each group. Thus there will be four distinct groups of subjects older frontal pole, younger frontal pole, older IFG, younger IFG. Each participant will take part in two TMS sessions, one target and one control session. The order of sessions will be counterbalanced across subjects. The primary endpoints of the study are to determine whether: 1. cTBS applied to frontal pole inhibits directed exploration within the younger and older groups 2. cTBS applied to IFG promotes both directed and random exploration within the younger and older groups The study is powered to answer these questions with 80% power at a threshold of p \< 0.05.
NCT05207397
Improved cardiorespiratory fitness following an aerobic exercise program elicits cognitive benefit in elderly subjects and memory improvement in Alzheimer's disease (AD). The physiological mechanism may be related to exercise-mediated change in circulating factors that permeate the brain. The response to each individual bout of exercise (i.e. the acute exercise response) may differ between subjects and be key to driving brain benefit. In young populations, the acute response to exercise can last hours and affect brain glucose metabolism. However, the field knows little about this acute exercise response in AD. Most exercise intervention trials designed to prevent and slow AD assess biomarkers at two fasting time points: pre- and post-intervention. The acute exercise response in the brain and periphery likely varies between subjects and diagnoses and provide key information regarding mechanisms of benefit. Our primary goals are to characterize the acute exercise response to exercise in the brain (glucose metabolism) and periphery (biomarker response) in aging and AD. We will identify relationships between exercise-related factors (i.e. heart rate, biomarkers) and change in brain metabolism and cognition. Understanding these mechanistic relationships will provide specific targets that can be used in future trials to develop individualized exercise prescriptions and maximize benefit.
NCT06968702
The ICOPE Brazil study aims to understand aging trajectories in Brazil, especially healthy aging trends based on intrinsic capacity, a collective of mental and physical capacities one may have to maintain their functional ability to execute daily life activities. Tests and questionnaires will be applied to collect data on mobility capacity, cognitive capacity, nutritional status, vision, and hearing (sensorial) capacities, and mental health. These assessments are in consonance with what the World Health Organization proposed in the Integrated Care for Older People Program (ICOPE). Participants will be followed up for three years, and the primary outcomes of interest are loss of intrinsic capacity, mobility impairment, cognitive impairment, incident depressive symptoms, loss of functional ability, incident frailty, incident sarcopenia, incident falls, hospitalization, multimorbidity, and mortality.
