Filter by:The Healthy Patterns Study intervention is a home-based activity intervention designed to improve symptoms of circadian rhythm disorders (CRD) and quality of life (QOL) in home-dwelling persons with dementia. We will use a randomized two-group parallel design of 200 people with dementia and their caregivers assigned to intervention or attention control groups.
The Etude Study is a multi-center, four-arm prospective dose-adjusting study designed to assess the tolerability, safety and efficacy of non-invasive sensory stimulation for patients with cognitive impairment.
The study has both quantitative and qualitative components. The objective of the quantitative study is: 1. To culturally adapt and refine Montessori activities for people living with dementia in Pakistan. 2. To determine the feasibility and acceptability of culturally-adapted group based Montessori intervention for people with dementia in Pakistan. 3. To build capacity and capability in dementia research (researcher training) The objective of the qualitative study is: To explore views on perceived effectiveness and sustainability of the study.
The study aims to use machine learning to predict the occurrence of episodic and autobiographical memory deficits as well as treatment response following a course of electroconvulsive therapy. Additionally, the neurophysiological correlates of the cognitive effects after a course of ECT will be investigated. Therefore, structural, resting-state and diffusion tensor images will be collected within one week before the first and after the last ECT treatment from severely depressed patients. Standard measures of cognitive function and specifically episodic as well as autobiographical memory will also be collected longitudinally and used for prediction. The study consists of 60 ECT receiving inpatients suffering from major unipolar or bipolar depression, 60 medication-only controls and 60 healthy controls.
The aim of this study is to investigate the effect of a transcranial electrical stimulation (tES) on a cognitive training in healthy elderly and memory impaired participants. In order to assess these effects different memory and attention tasks will be performed before and after the training as well as after 6 and 12 months.
The goal of this study is to test the efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) as a treatment for Mild Cognitive Impairment (MCI). Participants will be randomly assigned to one of three treatment groups: Group 1: Active Dorsolateral Prefrontal Cortex (DLPFC) rTMS; Group 2: Active Lateral Parietal Cortex (LPC) rTMS; and Group 3: Inactive rTMS (Placebo) control (evenly split between each coil location). Participation in the study takes approximately 7 ½ months-including a 2-to 4-week treatment phase (20 rTMS sessions) and a 6-month follow-up phase.
The two primary study objectives involve examining the effects of treadmill walking exercise training versus stretching-and-toning activities on the primary and secondary outcomes. Specific Aim 1: The first specific aim is to examine the effects of 3-months of treadmill walking exercise training compared with an active control condition on learning and memory outcomes in fully-ambulatory persons with MS who have impairment in learning new information. We hypothesize that those who undergo treadmill walking exercise training will demonstrate improvements in learning and memory relative to those who undergo stretching-and-toning activities. Specific Aim 2: The second specific aim is to examine the effects of 3-months of treadmill walking exercise training compared with an active control condition on hippocampal volume, hippocampal resting-state functional connectivity, and cardiorespiratory fitness in those persons with MS. We hypothesize that those who are randomly assigned to the treadmill walking exercise condition will demonstrate increases in hippocampal volume and resting-state functional connectivity (i.e., adaptive increases) and improved cardiorespiratory fitness relative to those in the stretching-and-toning condition.
Despite combined antiretroviral therapy (cART), milder forms of HIV-associated neurocognitive disorders (HAND) persist in 20-50% of persons living with HIV (PLHIV). Since more PLH are at risk for HAND due to aging, the frequency of HAND in PLHIV ≥ 65 years old is important to quantify for planning early intervention to attenuate both functional and occupational disabilities due to cognitive impairment.
It is estimated that by 2016, nearly 50% of HIV-positive individuals in the US will be aged 50 or older, and up to 60% of those will experience some degree of cognitive impairment as they age. The purpose of this study is to evaluate the contribution of the neuronal cholinergic receptor system to the cognitive impairments seen in adults aging with chronic HIV Infection. By using anti-cholinergic challenge drugs to reversibly "stress" cognitive functioning, the investigators hope to understand whether the presence of the HIV virus in the brain impairs the neural system necessary for normal cognition, more than would be expected from normal cognitive aging.
Objective: There have been a wide variety of interventions to assist with cognition and memory of older adults; however, it is often unclear if the interventions have an impact on daily life memory performance and goal attainment. The objectives of this study are to examine: 1) whether an intervention that involves a simple memory tool assists with daily life memory performance and goal attainment of older adults; and 2) whether the intervention has a different effect for individuals with healthy cognition versus individuals with mild cognitive impairment (MCI). Research Questions: Can a simple memory tool assist with daily life memory performance and goal attainment for older adults? Does the simple memory tool have a different effect for individuals with healthy cognition and individuals with MCI? Methods: The study will use a mixed 2 X 3 design with cognition (healthy, MCI) as the between subjects factor and time (session 1, 2, 3) as the within-subjects factor. There will be 40 older adults who have healthy cognition and 20 older adults who have MCI. The study will consist of 3 sessions for each participant. The sessions will be held once a week and incorporate: a) the Montreal Cognitive Assessment (MOCA) to determine level of cognition (healthy, MCI); b) the Prospective and Retrospective Memory Questionnaire (PRMQ) to help determine daily memory performance; c) a memory recall test for recent daily events to help determine daily memory performance; d) the goals of the participants using the Goal Attainment Scaling (GAS); and e) the development of checklists that are tailored to address goals. In between the sessions, participants will perform the checklists and update the diary with notes of what they want to remember on a daily basis. The hypotheses are that: 1) memory performance (i.e., measured with memory recall of daily events and PRMQ), and goal attainment will increase from session to session; 2) participants with healthy cognition will have better memory performance and goal attainment than participants with MCI; and 3) participants with healthy cognition will have greater gains in memory performance and goal attainment than participants with MCI.
