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.
Cognitive impairment after ischemic stroke can affect not only the social adaptation ability, but also affect the comprehensive rehabilitation of patients. The damage of cognitive impairment after ischemic stroke is not lower than the body function defect after stroke. Many studies have shown that oxidative stress is one of the pathophysiological mechanisms of ischemic cerebrovascular disease. Many studies have reported that the oxidative-reduction of cells plays an important role in the life activities of organisms, affecting the health, aging and death of the organism. In the recent years, some scholars have suggested that post-stroke cognitive impairment may be related to oxidative-reduction homeostasis of the body, but the relevant evidence is lacking and needs to be further explored. Therefore, the purpose of this study is to explore the effect of oxidation-reduction homeostasis on cognitive impairment in patients with ischemic stroke, and provide a theoretical basis for the prevention and treatment of cognitive impairment after ischemic stroke.
The major aim of this study is to investigate the effects of biofeedback assisted abdominal breathing training on improving the psychological and physiological distress in patients with ACI. In this randomized, controlled, single-blind trial, AIS patients were randomly assigned into experimental and control groups. The experimental group received four HRVBF training sessions. The control group received routine care. Repeated measures of HRV, Mini-Mental Status Examination (MMSE), Hospital Anxiety and Depression Scales (HADS), and Barthel Index for ADLs were collected prior to, and at one, and three months post-intervention.
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 aim of this study is to assess the brain correlates, as assessed with multimodal MRI, of working memory training in patients with severe traumatic brain injury (TBI)
Cognitive impairment is a significant health problem in the United States, resulting in costs over $100 billion a year. We will provide an efficient, effective, and financially intelligent solution to Primary Care Physician's to identify cognitive impairment in the earliest stages, delay progression through appropriate treatment, and to afford patients the opportunity to make future plans at a time when symptoms are mild and patients are able to make informed decisions concerning financial and life activities. This has the potential to delay devastating effects of cognitive impairment, and to lessen the financial burden on the health care system in the United States.
The proposed studies are aimed to measure Tau and P-Tau levels in pre- and postoperative blood, urine, feces and saliva, as well as to assess pre- and postoperative neurocognitive function in children (3 to 5 years old) who will have surgery under general anesthesia (single versus multiple exposures). The studies will establish a system to study biomarkers of the anesthesia/surgery-associated neurocognitive impairment in children and generate hypothesis that Tau or P-Tau serves as the biomarker of such neurocognitive impairment in children.
