NCT05980286
This project will develop and test 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.
NCT07122037
To assess the efficacy of two olfactory rehabilitation protocols (Nasal Airflow-Inducing Maneuver (NAIM) with or without ol-factory training) on olfactory function (sniffing stick test) and quality of life (questionnaire Self-MOQ and EORTC QLQ-H\&N35) in patients with total laryngectomy.
NCT06726616
Hispanic Americans are the fastest growing older adult group in the United States, disproportionally increasing the risk of an Alzheimer's disease and related dementias diagnosis. Efforts to reduce this risk and mitigate the related cognitive/physical declines are critical. The aim of this study is to assess the feasibility of enrolling older adults into an aging trajectory cohort, while generating preliminary data on associations of physical and cognitive aging trajectories. Our secondary objective is to generate preliminary data on the association of standard measures of physical activity and physical function with cognitive status. This study fits within our longitudinal research goal to reduce dementia incidence by understanding the mechanisms that drive the cognitive-physical aging trajectory.
NCT05462977
Researchers at the University of North Carolina at Greensboro conduct a single-arm intervention trial to investigate the efficacy of a music-based group exercise program for community-dwelling older adults. Up to forty participants will be recruited to participate in a music-based light-to-moderate intensity group exercise program for 20 weeks (30 - 40 min/day, up to 6 days/week), which is designed for older adults with or without functional limitations to exercise with chairs for the improvement of aerobic capacity, upper and lower body strength, and balance control at a gradually increasing pace. During the exercise sessions, participants will be trained to move in time with music playlists in synchronous tempos. Primary outcomes are cognitive performance, mobility, and health-related quality of life measured before and after the intervention. Secondary outcomes are adherence to the exercise program as a potential mediator of the treatment.

Poor sleep quality is a known risk factor for cognitive decline in the elderly. Hearteningly, sleep is also a prime target for behavioral modification. In this study, the investigators propose to test mindfulness-based training (MBT) as an intervention to improve sleep quality by reducing sleep fragmentation, and hypothesize that these improvements will mediate the beneficial effects of MBT on sustained and executive attention. MBT consists of a suite of techniques aimed at enhancing awareness and acceptance of one's internal (e.g., thoughts and feelings) and external experiences in the present moment. Learning these techniques has been shown to improve sleep quality in patients with primary insomnia, and in other conditions associated with sleep disturbance. There is also increasing evidence that mindfulness training enhances multiple facets of cognition, including components of attention. In this study, the investigators will recruit 120 participants in a randomized controlled design, with 60 participants receiving MBT, and 60 receiving a sleep hygiene education and exercise program (SHEEP). Each intervention will last 8 weeks. Before and after the intervention, the investigators will collect objective and subjective measures of sleep quality, resting-state and task-related functional magnetic resonance imaging scans, and performance on standard laboratory tests of attention. The investigators hypothesize that, relative to SHE, MBT will result in significantly greater improvements in sleep quality and attentional metrics. They also predict that the cognitive changes will be mediated by the changes in sleep quality. If a positive result is found, this would indicate the use of MBT as a cost-effective behavioral intervention to stabilize or even improve cognition in the elderly, thus reducing the risk of dementia in this vulnerable population.
NCT04904991
The purpose of this study aimed to evaluate the effect of the three-month Chan-Chung qigong program in improving physical functional performance and quality of life in patients with mild to moderate cognitive impairments.A quasi-experimental design was adopted. Subjects were recruited from cognitive impairments outpatients these subjects,41were assigned to the control group and 41 to the experimental group in which Chan-Chuang qigong was administered.

Attentional control, or individuals' ability to choose which stimuli in the environment they attend to and which they ignore, declines with older age. Studies from the past two decades suggest that mindfulness meditative practice, such as a standardized mindfulness based stress reduction programs, may increase the efficiency of attention networks.To date, the majority of studies that have related mindfulness meditation practice to attentional control have been based on retrospective self-reported mindfulness or cross-sectional measurement in experienced meditators. More recent experimental studies using pre-post training designs have shown that meditation-naïve individuals can experience attentional improvement with mindfulness intervention. This study seeks to elucidate the time course and process by which such attentional improvements might be achieved. This research study investigates change in attentional control as participants progress through an 8-week mindfulness-inspired training (MIT) intervention, and has two specific aims: 1) to determine the time course of change in attentional components such as cognitive control and sustained attention as a consequence of MIT; attention will be measured weekly for 3 weeks before, 3 weeks after, and during 8 weeks of MIT. 2) To investigate the extent to which change in attentional performance is coupled/correlated with markers of emotion regulation, perceived mindfulness, and perceived mind wandering.
