Filter by:Different cognitive intervention approaches have been developed to attenuate decline (e.g., cognitive engagement, training, or stimulation), but it is not clear which approaches are efficacious. It is also not clear when, along the continuum of normal cognitive aging to mild cognitive impairment (MCI-a transitional stage before dementia onset), it is most efficacious to intervene. This randomized clinical trial will determine the efficacy of a novel cognitive engagement intervention approach (music training) as compared to cognitive stimulation (which will serve as a stringent, active control). Grounded in theory, the central hypothesis is that interventions enhancing central auditory processing (CAP), a strong, longitudinal predictor of MCI and dementia, will improve cognition. Music training is increasingly recognized as a feasible means to attenuate age-related cognitive decline. Prior research and preliminary data suggest that intense piano training enhances CAP and is likely more effective than cognitive stimulation. Correlational studies indicate superior CAP, executive function, and other cognitive abilities for adults with formal music training compared to non-musicians. The specific aims of the study are to examine the efficacy of music training relative to cognitive stimulation (active controls) to improve CAP, cognition, and everyday function among older adults with and without MCI. The efficacy of music training will be established and moderating effects of MCI status will be examined. The proposed study further aims to elucidate the underlying mechanisms of effective cognitive intervention approaches by exploring mediators of training gains. The proposed study is the first phase II randomized trial of music training to enhance older adults' cognition. Mediation analyses will elucidate the underlying mechanisms of intervention effects.
This is a non-pharmacological study evaluating the effects of SMR/delta ratio and beta1/theta ratio neurofeedback trainings on cognitive performance and electrical brain activity in elderly with mild cognitive impairment.
Nearly 1 in 10 older Americans have dementia, which is a devastating condition that leads to a progressive loss of independence and functional status. Mild cognitive impairment (MCI) is an intermediate stage between the expected cognitive decline of normal aging and the more-serious decline of dementia. The investigators have developed a novel, integrative exercise program called Preventing Loss of Independence through Exercise (PLIE) that incorporates elements from Eastern and Western exercise modalities and is designed to build and maintain the capacity to perform basic functional movements while increasing mindful body awareness and enhancing social connection. Pilot study results suggest that PLIE is associated with meaningful improvements in physical function, cognitive function and quality of life in individuals with dementia, as well as reduced caregiver burden. The goal of the current study is to perform a randomized, controlled trial to test the efficacy of PLIE in older adults who have MCI but who do not yet have dementia. The investigators will also investigate the neural mechanisms underlying PLIE by acquiring brain imaging measures.
This study will investigate the effect of Action Observation Teaining (AOT) on gait variables and global cognitive functions in older adults with mild cognitive impairment (MCI). The specific objectives are 1) to compare gait variables and global cognitive functions among the AOT with gait training, gait training, and control groups at before training, after training, and follow up and 2) to compare gait variables and global cognitive functions among before training, after training, and follow up in each of the groups.
This study evaluates the application of non-invasive brain stimulation in the treatment of Mild Cognitive Impairment (MCI) in adults aged 55-85. Half of the participants will receive transcranial direct current stimulation (tDCS), while the other half will receive sham (like placebo) stimulation.
Neurodegenerative diseases such as Mild Cognitive Impairment, Alzheimer's, and dementia affect millions of Americans. Although these diseases are heavily researched, there is very little research examining the impact of attenuated carotid artery endothelial function and cerebrovascular blood flow on cognitive function. This is surprising, as cerebrovascular oxygenation has been shown to be strongly associated with reduced cognitive function and the pathogenesis of neurodegenerative diseases. For example, hypertension, diabetes, and high cholesterol have been shown to increase the risk of Alzheimers related dementia. Therefore, the purpose of this proposed study will be to examine the effects of MitoQ supplementation on carotid artery vasodilatory function and cerebrovascular blood flow in those suffering from Mild Cognitive Impairment (MCI). MitoQ is a mitochondria-targeting antioxidant that can improve nitric oxide production in the blood vessel, which should improve endothelial function, and thus cerebrovascular blood flow.
The Longitudinal Early-onset Alzheimer's Disease Study (LEADS) is a non-randomized, natural history, non-treatment study designed to look at disease progression in individuals with early onset cognitive impairment. Clinical, cognitive, imaging, biomarker, and genetic characteristics will be assessed across three cohorts: (1) early onset Alzheimer's Disease (EOAD) participants, (2) early onset non-Alzheimer's Disease (EOnonAD) participants, and (3) cognitively normal (CN) control participants.
Muscle relaxation has been reported to be effective in alleviating anxiety and agitation symptoms in patients with dementia, but no studies have examined the effects of muscle relaxation therapy on cognitive function changes. Therefore, the purpose of this study is to compare and validate the improvement of cognitive function in patients with mild cognitive impairment and early alzheimer's dementia aged 50 to 85 years after performing muscle relaxation machine massage regularly.
The purpose of this pilot study will be to test whether Kundalini yoga (KY) and Kirtan Kriya (KK) yogic meditation is superior to Memory Enhancement Training (MET) for improving cognitive functioning, health (including cardiovascular factors), and mood in women with high AD risk.
Elderly humans have an increased risk of dementia which begins as mild defects in memory called mild cognitive impairment. Glutathione (GSH), a key endogenous antioxidant has been linked to cognition. This exploratory study will investigate mechanisms linked to GSH for cognitive impairment (and improvement) by studying humans with mild cognitive impairment who will be evaluated 12-weeks after receiving either N-acetylcysteine and glycine (GSH precursors), or receiving alanine, and a further 12-weeks after stopping these supplements.
