Filter by:The Digital Cognitive Multi-domain Alzheimer's Risk Velocity (DC MARVEL) study is a 2-year randomized controlled trial on dementia prevention. The purpose of this study is to determine the effect of a digital cognitive health program on dementia risk, cognitive function, and general health outcomes in middle age to older adults compared to a control group that receives health education.
Older women with cardiovascular disease (CVD) are at greater risk for memory loss, an important public health issue due to the negative effects to quality of life and health care costs. This research will be the first to examine the independent and combined effects of a lifestyle physical activity intervention and cognitive training on memory performance and memory-related serum biomarkers in this vulnerable population. The investigators will incorporate a practical lifestyle approach that can be delivered in the home and community settings to prevent or delay memory loss in older women with CVD.
The study will examine the efficacy of high definition transcranial direct current stimulation (HD-tDCS) and its influence on episodic memory in patients with amnestic mild cognitive impairment and a history of Traumatic brain injury. Ten sessions of HD-tDCS to the dorsal anterior cingulate region is expected to result in improvements in episodic memory measures immediately following the last session and at a 3-month follow-up.
Military deployment is associated with increased risk of mild cognitive impairment (MCI). Combat stress related memory deficits has been well documented. Mild cognitive impairment such as memory deficits are the most common and earliest symptoms of Alzheimer's disease and related dementia (ADRD). The complaints about declined memory are common in healthy and cognitively intact civilian older adults, but less understood in aging Veterans. Brain training strategies to enhance cognitive skills and especially memory processes are unmet needs in aging Veterans who are at additional risk for MCI induced by ADRD. Since currently there is no effective drug treatment to stop cognitive decline, non-invasive brain training to boost memory functions in older Veterans is an increasingly attractive option to attenuating decline in memory.
The study aims to (1)compare differences of global cognitive function, working memory, executive function, language function, and quality of life between institutionalized older adults with MCI and with mild AD. Doing so, we can have a better understanding of the cognitive performance and life quality at pre-dementia and dementia;(2)explore the effects of the interventions with different acupoints(acupoints on head, acupoints on body, and acupoints on head and body) on global cognitive function, working memory, executive function, language function, and quality of life among institutionalized older adults with MCI and with mild AD;(3) further investigate the long-term effects of the interventions on global cognitive function, working memory, executive function, language function, and quality of life among institutionalized older adults with MCI and with mild AD; doing this, we can explore the pathological mechanism of the changes in the cognitive function through neuropsychological assessments and the association between the changes in cognitive function and in quality of life. We will recruit 32 residential care homes, with 256 older adults with MCI and with mild AD for this single blind cluster randomized controlled trial with repeated measures study. The facilities will be randomly assigned to the acupoint-on-head group, acupoint-on-body group, acupoint-on-head-and-body group and control group, with a ratio of 1:1:1:1. Interventions are developed based on the theory of Chinese medicine. Except routine care, the intervention groups will receive the acupressure once per day, five times per week, a total of 12 weeks. Data will be collected at baseline, the 4th and 8th weeks during the intervention, the end of the intervention, and the1st, 4th, and 8th months after the intervention. The control group only will receive routine care and data collection is the same as the intervention groups. Data assessors will not involve in the interventions and not know the group allocation. The data analysis will use intent-to-treat analysis. The multiple regression analysis, mixed effect model for repeated measure analysis, subgroup analysis, and product-of-coefficient test will be performed to examine the effects of the interventions on cognitive function and quality of life, and the associations among the changes in the dependent variables.
There is accumulating evidence suggesting that Greek Mountain Tea may have a positive impact on conditions involving cognitive deficits, such as Mild Cognitive Impairment (MCI) and AD. More specifically, greek mountain olympos tee is rich in essential oils, flavonoids, diterpenes and phenylpropanes, which are primarily responsible for its pharmacological properties. Its confirmed antioxidant properties are what make mountain tea promising against Alzheimer's disease and other neurodegenerative diseases. It has also been proven to possess cholinergic and cognitive enhancing capabilities. Greek Mountain Tea is deeper studied and it shows promising results in neuroprotection against AD through various suggested mechanisms, such as the enhancement of amyloid-beta clearance in the brain and the inhibition of neurofibrillary tangles formation. The aim of the study is to evaluate the beneficial effect of Greek Mountain Tea in patients diagnosed with mild cognitive impairment MCI. Study Type: Interventional Study Design: Allocation: Randomized Intervention Model: Parallel Assignment Masking: Double Blind (Subject, Investigator) Primary Purpose: Prevention
Chemotherapy-induced peripheral neuropathy (CIPN) is a common, but not well understood complication to treatment with chemotherapy. In this study the investigators will investigate a novel method for early detection of CIPN and compare it to other methods in patients treated for haematological cancers.
Coronavirus disease 2019 has forced worldwide the implementation of unprecedented restrictions to control its rapid spread and mitigate its impact. The Spanish government has enforced social distancing, quarantine and home confinement. This restriction of daily life activities and separation from loved ones may lead to social isolation and loneliness with health-related consequences in community-dwelling older adults with mild cognitive impairment or mild dementia and their caregivers. Additionally, an inadequate access to healthcare and social support services may aggravate chronic conditions. Technology home-based interventions emerge for combating social isolation and loneliness preventing the risk of viral exposure. The aim of this multicentre cohort study is to explore, analyze and determine the impact of social isolation on: 1) cognition, quality of life, mood, technophilia and perceived stress of community-dwelling older adults with mild cognitive impairment or mild dementia, and on caregiver burden; 2) health and social care services access and utilization, and 3) cognitive, social and entertainment use of ICTs. This study will be conducted in two Spanish regions Andalucía (Málaga) and Cataluña (Tarrasa). In total 200 dyads, consisting of a person with mild cognitive impairment or mild dementia (PMCI/MD) and their informal caregiver will be contacted by telephone. Potential respondents will be participants of the SMART 4 MD (N=100) and TV-AssistDem (N=100) clinical trials. The change in means in the variables will be analyzed comparing baseline results in the previous studies with those during and after confinement using the ANOVA test of repeated measures or the non-parametric Friedman test if appropriate. The performance of a multivariate analysis of variance (ANCOVA) to introduce possible covariates will also be contemplated. A 95% confidence level will be used.
High blood pressure and poor cognitive function are two common health problems among older adults in the United States. They are also closely related because high blood pressure may lead to negative changes in brain structure and function such as poor brain blood flow that can cause poor cognitive function. Executive function is one type of cognitive function that let people plan and perform difficult tasks. It is commonly damaged by high blood pressure. It is also very important for older adults because they need good executive function to live on their own. Tai Chi is a good exercise option for older adults because it is safe, fun, and social. Research studies show that Tai Chi can reduce blood pressure and improve cognitive function, especially executive function. However, researchers do know if these heart and brain health benefits of Tai Chi are connected. In the ACTION study, researchers will first measure how a single session of Tai Chi followed by a 12-week online Tai Chi program with easy movements changes blood pressure and cognitive function, focusing on executive function. Then, researchers will test if these changes in heart and brain health are connected, and if they are connected through the changes in brain structure and function. Both the single session and 12-week online Tai Chi program will be practiced by a group of older adults with high blood pressure and normal cognitive function. They will be new to Tai Chi and not exercising regularly. The hypotheses of the ACTION study are that practicing Tai Chi is good for the heart and brain of older adults with high blood pressure. Specifically, relaxing Tai Chi with gentle movements will reduce blood pressure, and thereby improve cognitive function, particularly executive function.
The purpose of this study is to investigate how RA affect the brain structures in RA-patients and if anti-inflammatory treatment that target TNF-α or JAK OR physical training of hands has positive impact on neuropsychiatric symptoms and morphological changes in the brain caused by the disease. The goal of this research project is to improve the knowledge of morphological changes in brain developed in connection to RA and to identify clinical and serological markers to predict development of those changes and finally, to investigate if anti-rheumatic interventions counteract destructive processes in the central nervous system (CNS) and improve the patient's health with respect to functionality, pain experience and psychological well-being.
