Filter by:Mild Cognitive Impairment (MCI) is a term used to describe the transitional stage that occurs between normal aging and the onset of dementia. Spatial disorientation is often considered a significant indicator for diagnosing dementia. Numerous studies have documented deficits in both the allocentric and egocentric spatial frames of reference, as well as difficulties in transitioning between them, in individuals with MCI. Rapid advances in computing technology have enabled researchers to conduct cognitive training and rehabilitation interventions with the assistance of technology. Therefore, the aim of the study is to use virtual therapeutics to train MCI spatial memory.
The objective of this study is to investigate the feasibility of a virtually-delivered 6-month exercise and nutrition intervention in older adults with executive subjective cognitive decline (SCD). Feasibility will be determined by recruitment, retention, and adherence rates. Preliminary changes in cognition, physical function, and quality of life will be assessed as secondary outcomes. The study will recruit 140 participants aged 65 to 80 who report they feel that their memory or other thinking abilities are declining. Participants will be randomized into one of four study arms receiving different combinations of healthy lifestyle interventions. Assessments will be conducted virtually at baseline, post-intervention (6 months), and follow-up (12 months). All intervention sessions and assessment visits will be conducted online using the Zoom Healthcare platform and participants will log on using their own devices from home.
Digital medicine is a useful clinical resource for people with cognitive disorders. Scientific literature has shown that in people with dementia neuropsychological instruments administered in remote are characterized by high psychometric quality and satisfaction levels. However, evidence about the reliability of remote neuropsychological domain-specific tests is still limited in the Italian context. The principal aims of the study will be 1) to evaluate the reliability of the remote administration of neuropsychological screening and domain-specific tests compared to the face-to-face administration in patients with cognitive disorders; 2) to assess the feasibility and level of satisfaction of patients and caregivers about remote administration. All participants will be submitted to both face-to-face and remote neuropsychological assessment (by videoconference) in a counterbalanced cross-over design. Finally, all patients and/or caregivers will complete a satisfaction questionnaire about the remote administration.
The goal of this interventional study is to determine the impact of high potency THC product use on cognitive function of young adults aged 21-25. The main question it aims to answer is: will cannabis users who switch to less potent THC products demonstrate improved cognitive function compared to baseline? Other questions this study aims to answer include: - Can researchers accurately assess THC consumption among frequent cannabis users? - Can researchers effectively incentivize cannabis users to use less potent THC products? - Do genetic variations in THC metabolism impact urinary THC excretion? - Do genetic variations in THC metabolism impact cognitive performance in cannabis users? - Are quantitative urinary THC values predictive of cognitive impairment? - How can researchers use research findings to inform harm reduction practices for people who use cannabis? Participants will submit blood and urine samples and be incentivized to use less potent THC products.
The goal of this interventional study is to assess the effects of either physical exercise program or combined with cognitive training (dual motor and cognitive training program) on breast cancer survivors. The main questions it aims to answer are: - Analyze the effectiveness of a supervised dual-task training program or a physical exercise program on the executive functions of the participants. - Evaluate the impact of both interventions on physical function, emotional aspects, and important biomarkers related to muscle-brain crosstalk. Participants will perform a 20-week supervised and controlled program, three times a week, along with weekly calorie and step challenges. Researchers will compare the dual-task training group, with the physical exercise group, and with a control group, which will perform the guideline recommendations of physical activity (non-supervised) to see how these intervention approaches can impact cognitive functions, physical functions, emotional aspects, and biomarkers related to muscle-brain crosstalk. Assessments will take place at three-time points: at baseline, after the intervention (20 weeks post-baseline) and after a 12-week follow-up period (32 weeks post-baseline).
The investigators propose a proof of concept RCT (randomized clinical trial), testing the efficacy of intranasal insulin (INI) with semaglutide, a combination therapy with strong biological plausibility to benefit impaired cognition through vascular mechanisms, in older adults with MetS (metabolic syndrome) and MCI (Mild Cognitive Impairment), who are enriched for cerebrovascular disease and at high dementia risk. The study will focus on cognitive and biological outcomes, allowing identification of relevant mechanisms.
The goal of this pilot randomised clinical trial is to compare a 12-week Healthy Body & Mind Program to usual care in older adults living with cognitive decline and osteoarthritis. The main questions it aims to answer are: - Does the Healthy Body & Mind Program improve health-related quality of life in older adults living with cognitive decline and osteoarthritis (pre/post and intervention/control)? - Does the Healthy Body & Mind Program improve other health outcomes (cognition, pain, anxiety/depression, physical function) in older adults living with cognitive decline and osteoarthritis (pre/post and intervention/control)? Participants will complete a co-designed and multidisciplinary 12-week program that includes physical activity and lifestyle education (nutrition, social activity and managing anxiety/depression). Researchers will compare outcomes between the intervention group and a wait-list control to see if there are difference in outcome measures (quality of life, cognition, pain, anxiety/depression, physical function).
Ketamine is a NMDA-receptor antagonist that promotes synapse formation and has been shown to rapidly improve symptoms in depression. Even a single dose of ketamine has been shown to improve depression and cognition with short-term memory, inhibitory control, cognitive flexibility, and processing speed showing improvements within days of treatment. The mechanism behind ketamine's rapid action is not clear but some groups have speculated it may be related to enhanced neuroplasticity, particularly in the frontal areas and the hippocampus. If this mechanism is accurate, ketamine may be especially effective in treating mild cognitive impairment and depression (MCI-D) where changes in the hippocampus and frontal areas have been implicated. Although few studies have been published on the effects of ketamine in older adults, some small pilot studies suggest that ketamine treatment might be effective in improving depression in older adults and relatively safe. There are no studies looking at the effects of ketamine treatment in patients with MCI-D. The research team hypothesize that IV ketamine treatment will be well-tolerated and will improve depression and cognition in patients with MCI-D. The study team will explore the effects of brain imaging abnormalities and amyloid biomarker status on the responsiveness to ketamine. The study team will conduct an open-label pilot study designed to gather data to support an application for a larger NIH-funded study.
The objective of this study is to develop and assess the feasibility, acceptability, and preliminary efficacy of a community-delivered, affordable, and accessible hearing care intervention tailored to the needs of community-dwelling Korean American (KA) older adults with mild cognitive impairment (MCI) and their care partners that integrates a low-cost over-the-counter amplification device and hearing rehabilitation through a randomized controlled pilot study. Each dyad will consist of the study participant and their care partner.
The goal of this randomized controlled trial is to compare the effectiveness of two innovative interventions aimed at preventing cognitive decline and work-related problems to enhanced usual care in improving quality of life in people with multiple sclerosis. Secondary objectives are: - to compare the effectiveness of the investigated interventions in improving cognitive, psychological, and work functioning, and in enhancing the brain's functional network - to examine which factors (i.e., baseline cognitive, psychological, work, and brain MRI-parameters) are predictive of the response to the investigated interventions - aim to qualitatively reflect on the process and outcome of the investigated interventions considering the perspectives of relevant stakeholders to allow for smooth and successful implementation in clinical practice Participants will follow the intervention for four months, with follow-up measurements at six months after intervention and 12 months after intervention.
