Filter by:The study will test a multifaceted strategy for implementing an intensive blood pressure intervention protocol targeting systolic BP <120 mmHg on cognitive decline in racial minority and low-income hypertensive patients in primary care. The proposed study will generate urgently needed data on effective, adoptable, and equitable intervention strategies to reduce blood pressure-related cognitive decline in low- income and minority populations. If proven effective, the implementation strategy for intensive blood pressure reduction could be adapted and scaled up in diverse primary care settings to prevent cognitive decline and clinical dementia.
More than 4.4 million patients receive home health services following discharge from the hospital or rehabilitation facility. A substantial number (70%) are older adults with subjective cognitive decline (SCD), an early clinical sign of Alzheimer's disease and related dementia. SCD is associated with diminished activity performance, poor quality-of-life and other adverse health outcomes (e.g., depressive symptoms). Home health patients with SCD often require more time, structure, and guidance to complete tasks and adjust to new skills and environments. Support is especially important during this high-risk period of transition between care settings. We propose a new home health care delivery model in partnership with Kindred at Home (KAH), a division of Humana that encompasses 400 programs across 40 states. DEMA-Pro builds on five preliminary studies that demonstrated high feasibility, acceptability, and positive preliminary effects on health outcomes (physical function, mood, and QoL). DEMA-Pro will be refined for delivery by home health services staff to patients with SCD and their informal caregivers. The overall goal of this research will be to conduct a pragmatic cluster randomized controlled trial (RCT) of DEMA-Pro to improve outcomes in-home health service patients with SCD. In the current R61 pilot phase, we will establish the trial's organizational structure and processes and pilot test DEMA-Pro in 4 home health services sites. In a subsequent trial, we plan to conduct a full pragmatic RCT in a group of Kindred KAH sites comparing DEMA-Pro to usual care. Consistent with the spirit of a pragmatic trial, we will use existing data sources including electronic Medicare OASIS (Outcome and Assessment Information Set) data, and QoL to characterize the cohort and measure outcomes. Thus, the focus of the pilot phase will be to ensure all processes are in place to conduct the subsequent RCT. Aim 1. Establish the organizational infrastructure and programmatic processes needed to conduct a pragmatic cluster-randomized control trial of the DEMA-Pro intervention versus usual care. A Steering Committee will lead the project and coordinate the activities of 3 Work Groups: Regulatory and Operations; DEMA-Pro Intervention Protocol; and Data Management and Analysis. Aim 2. Pilot test the DEMA-Pro training protocol in 4 KAH North Region locations and refine as indicated.
The purpose of this platform study is to evaluate the effect of anti-inflammatory agents on cognition in early Alzheimer's disease. Additionally, the safety and tolerability of these anti-inflammatory agents and the effects on central and peripheral inflammation will be evaluated.
The aim of this study was to compare the effects of three months' endurance training and three months' endurance-strength training on selected psychological aspects in women with abdominal obesity.
Background: Dementia is a debilitating and devastating disease impacting the individuals, their families, and the health care system. According to the World Health Organization the dementia epidemic could overwhelm the global health care system and undermine social and economic development. Currently, no curative treatment for dementia exists despite immense research activity. The cognitive and functional impairment in dementia, especially Alzheimer's disease (AD), develop slowly decades before clinical signs emerge. This knowledge has led to the recognition of a prodromal period of mild cognitive impairment (MCI), between normal cognition and dementia. This is at present the earliest stage for intervention in dementia; even a short delay in dementia progression will have a large impact on global economy and health care. Objectives: In this clinical multicenter study, we aim to investigate the efficiency and cost-effectiveness of working memory training in MCI. To identify high responders to training analysis of genetic markers, relative's stress and craniospinal clearance will be performed. Participants and methods: This study is a blinded, randomized and controlled trail that will include 213 participants, diagnosed with MCI, included from five Norwegian Memory clinics in four health care regions. The groups will be randomized to either two training periods, one training period or active control. The intervention is computerized working memory training. Neuropsychological status, activities of daily living (ADL), and relative stress and quality of life will be assessed at baseline and 3, 6, 12 ,24 and 48 months after training. Structural MRI will be performed at baseline, and 3 and 6 months after training. For participants in the REACT MCI glymphatics substudy craniospinal clearance will be measured at baseline. A cost-utility analysis will be performed to evaluate if the working memory training is more cost-effective compared to the active control group in the MCI phase, taking a societal perspective.
The purpose of this study is to look at the best ways to prevent cognitive decline (loss of memory and/or functioning) in midlife and older Latino adults living with HIV.
This research is being done to determine if computerized administered cognitive fitness activities will improve thinking and depression in older depressed adults who are being treated with antidepressants. The investigators are also interested in whether participating in the treatment will result in changes to brain activity measured with magnetic resonance imaging (MRI).
The study aims to assess the preliminary efficacy of a Dual-Task Zumba Gold (DTZ) intervention that will support physical and cognitive training among community-dwelling persons with mild cognitive impairment (MCI). A 12-week Dual-Task Zumba Gold (DTZ) intervention will be implemented among 30 participants with MCI in the treatment group, while health education will be provided to another 30 subjects allocated in the control group. Changes in global cognitive function, together with the quality of life, mood, functional mobility, and bodily measures, will be re-assessed after the 12-week intervention and a 6-week follow-up period. Quantitative and qualitative methods will also be employed to assess the feasibility and acceptability outcomes of the study.
Cognition is the way people use their brains to think, understand, remember and make decisions. Cognitive changes are often seen even up to 1 year after surgery. Whether these changes are more than what is expected for someone's age and morbidities is still uncertain. Due to the COVID-19 emergency, many elective surgeries have been delayed, which is stressful for patients, but also represents an opportunity of understanding better how surgery can impact cognitive abilities. The purpose of this study is to explore if and how cognitive performance changes over time for patients aged 65 years or older, whose surgery has been postponed. due to the COVID-19 emergency, following and assessing the cognitive performance of these patients over time before and after surgery. In particular, in this study, the participant's cognitive performance will be assessed periodically with a computer-based instrument for cognitive testing, self-administered at home, in which tests are based on playing cards.
This study is being done to evaluate the safety and feasibility of using Dasatinib and Quercetin together in subjects with Mild Cognitive Impairment (MCI) or Alzheimer's disease.
