Filter by:Age-related cognitive impairment is a wide phenomenon. Mild cognitive impairment is a transitional stage between Dementia and normal cognition.Mild cognitive impairment (MCI) is a syndrome that has been recognized in older adults and it has become a topic of a major focus on clinical care and research. In people with this condition, there are cognitive deficits and these have adverse effects on activities of daily living . These patients cannot recognize their impairment. Mild cognitive impairment is a risk factor for dementia.
The Shared Decision Making about Medication Use for People with Multiple Health Problems study will assess the feasibility and acceptability of a deprescribing educational intervention in primary care for patients with mild cognitive impairment or dementia and/or multiple chronic conditions (MCC), the patients' care partners, clinicians, and medical assistants. The intervention consists of the following strategies: 1) a patient/caregiver component focused on education and activation about deprescribing, and 2) a clinician component focused on increasing clinician awareness about options and processes for deprescribing in the MCI/dementia and/or MCC population. Clinicians will each be asked to participate in a single, 15-minute educational session on deprescribing, and medical residents will receive a 45-minute lecture. Patients, caregivers, clinicians, and medical assistants will participate in a single one-on-one debriefing interview.
The aim of this study is to investigate the effect of cognitive training combined with physical exercise on cognitive function, physical performance and frailty indicators in the hemodialysis population.
The overarching aim is to develop and deploy a multidomain intervention delivered on a mobile application to help middle-aged to older adults reduce their risk for dementia by improving a set of modifiable lifestyle risk factors associated with cognitive decline/dementia. This registration concerns the Pilot Feasibility study which examines different aspects of feasibility in a small-scale randomized pilot study, before implementing an efficacy study on a larger sample. A secondary objective is to determine whether the program can result in a larger improvement on risk factors (measured with Behavioural Risk outcomes) compared to a control intervention. It is expected that persons enrolled in the Luci program show larger change in Behavioural Risk outcomes than those enrolled in the comparator condition.
The main purpose of this study is to compare donanemab to aducanumab on brain amyloid plaque clearance in participants with early symptomatic Alzheimer's Disease (AD).
This project is focused on conducting a home-based, thinking while moving exercise intervention for adults 65 years or older, who have mild cognitive impairment, that will integrate several effective training modalities including non-contact cardio-kickboxing, stepping exercise, balance/functional training, and muscle strengthening. Cognitive function, physical function, and dual-task abilities will be assessed over the 12-week intervention and comparisons will be made between participants in the exercise intervention and control participants receiving no intervention.
This is a Phase 2a, randomized, placebo-controlled, double-blind, crossover study to evaluate the effects CST-2032 administered with CST-107 on cognition in subjects with Mild Cognitive Impairment (MCI) or mild dementia.
Delirium is common in older adults after inpatient surgery and may be associated with cognitive decline. Advances in surgical and anesthetic techniques have led to increasing numbers of older adults undergoing surgery on an outpatient basis. However, few studies have investigated cognitive disorders of older adults before or after ambulatory surgery. Increased age and pre-existing cognitive impairment are strong risk factors for cognitive decline after surgery, yet older adults are not screened for cognitive impairment before surgery. Existing screening tools require specially trained staff for test administration and in-person testing. Virtual cognitive screening has not been evaluated in surgical patients. In this study, investigators will determine the feasibility of using Cogniciti's Brain Health Assessment (BHA) - a validated online cognitive screening tool that can be self-administered from a patient's home before surgery - to screen older adults before ambulatory surgery.
In the United States and around the world, people are living longer lives. As the population ages, so does the number of older adults who may experience declines in memory, attention, reasoning, or other thinking skills. Some of these changes in cognition can be treated and reversed if caught early. Others can be slowed down and hopefully one day prevented. Unfortunately, people with cognitive decline or very mild dementia often are not recognized until late in the disease course when treatments are less effective. As the first health care professional most people reach out to about medical concerns, primary care providers play a critical role in detecting cognitive decline early. While many primary care providers conduct cognitive screening at Medicare Annual Wellness Visits and when patients voice concerns, 9 out of 10 would like more information about who to screen, which assessment tool to use, and what to say if screening is positive. Deciding who to screen with a brief cognitive assessment tool is a key part of the process because not everyone needs to be screened, and primary care providers already face time pressures to address the obvious and immediate concerns of their patients. The long-term goal of this project is to develop a risk assessment and cognitive screening tool that requires minimal time and effort from primary care providers or their staff and is sensitive to cognitive decline in older adults from diverse educational and racial/ethnic backgrounds. The tool will be integrated into electronic health record systems to make it easy for primary care providers and patients to see results. The specific aims of the first phase of the project are to modify an existing dementia risk screening index to identify older adults who are at high-risk for cognitive impairment, develop a brief cognitive assessment tool using tasks that are easy for older adults to perform yet are sensitive to cognitive decline, confirm their utility in 150 people with varying levels of cognitive abilities that have already been well defined, and test ways to integrate findings into the electronic health record. The specific aims for the second phase are to further test the effectiveness of the newly developed tool in 250 older adults receiving care in a primary care clinic, to find out from primary care providers using the tool how much they liked it and if it was useful and easy to use, and to integrate findings into multiple electronic health record systems. Findings from this project will fill a gap in the existing toolkit of primary care providers and will make screening for cognitive decline quick, easy, and effective.
The investigators have developed a low-risk transcranial Electrical Stimulation (tES) treatment that has improved learning and performance in young adults up to nearly 4 times when compared with a sham control. This randomized pilot trial will determine if this same tES protocol improves memory in older adults (50-90 years old) who are healthy, and separately in older adults with mild cognitive impairment (MCI) or early stage Alzheimer's disease (AD). TES will be applied to the right temple and left arm for up to 40 minutes. MRI images, along with other measures, may be obtained before and after tES. If effective, this intervention may help to improve the quality of life for AD patients and their families.
