Filter by:The goal of this placebo-controlled double-blind Phase 2 clinical trial is to test in people with early Alzheimer's Disease. The main questions it aims to answer are: - Does treatment with fasudil, a ROCK-inhibitor, lead to significant improvement in working memory (based on computer-based working memory composite scores) compared to placebo in individuals with early Alzheimer's disease (AD) over 12 months? - What is the effect of fasudil treatment for 12 months on other cognitive functions, brain metabolism measured by Fluorodeoxyglucose Positron Emission Tomography (FDG-PET), and other relevant clinical functions and biomarkers in individuals with early Alzheimer's disease (AD)? - Treatment will be escalated to a maintenance dose of 120 mg total daily dose for up to 50 weeks, with regular clinic visits for efficacy and safety evaluations. - Assessments will include cognitive tests, FDG-PET scans, and biomarker analyses, with follow-up by the Data and Safety Monitoring Board for ongoing safety review. The study will compare participants receiving fasudil with those receiving placebo to see if fasudil treatment leads to improvements in cognitive functions, brain metabolism measured by FDG-PET.
The purpose of this study is to assess the feasibility, acceptability, and fidelity of an 8-week intervention where peer coaches will deliver depression care to adults 60 years of age or older who have depression and subjective cognitive decline.
This is to find out the effectiveness of cognitive and physical function training for patients with mild cognitive impairment. It is for the prevention and treatment of dementia in the future. randomized, Pilot Study.
The purpose of this research is to determine the extent to which oculomotor function accurately detects THC-impairment, if cannabis use experience impacts this detection threshold, and to examine how the oculomotor index corresponds to a measure of sustained attention. A double-blind, placebo-controlled, within-subjects crossover design will be used to examine the dose-effects of THC (0, 5mg, 30mg) on oculomotor performance tasks and a sustained attention task in frequent and infrequent cannabis users. Results from the study will advance the investigators' understanding of the effect of THC and cannabis use frequency on oculomotor function and sustained attention, and will directly inform the validity of the investigators' oculomotor platform for identifying acute THC- induced impairment in frequent and infrequent users.
Evidence shows that people with dementia have a higher prevalence of sleep disturbance, cognitive decline, behavioral disturbance, and experience motor dysfunction. These symptoms are interrelated. However, few randomized controlled trial (RCT) studies implement dual-task training for mild cognitive impairment and mild dementia, especially for those who experience sleep problems and behavioral disturbances. Therefore, this study aims to analyze the effect of dual-task training in improving global cognitive function, executive function, working memory, sleep, behavioral disturbances, balance, and flexibility among people with mild cognitive impairment and mild dementia. The main questions it aims to answer are: 1. . Does dual-task training affect primary outcomes (global cognitive function, executive function, and working memory) 2. . Does dual-task training affect secondary outcomes (including sleep quality, behavioral disturbances, balance, and flexibility) for people with mild cognitive impairment and mild dementia?" The length of dual-task training is 12 weeks; sessions are 3 times per week, each session lasts 45 minutes, and total sessions are 36. There are three groups of intervention (dual-task training, cognitive training, and motor training). While the control group receives the usual care. Researchers will compare the experiment and control groups to see the effect of the dual-task training.
The objectives of this study are to demonstrate the feasibility of implementing a deprescribing nudge intervention using pragmatic methods, confirm that outcomes can be feasibly measured and evaluated at scale in a subsequent embedded pragmatic clinical trial (ePCT), and explore representativeness of persons living with dementia and care partners identified.
The goal of this clinical trial is to Explore and verify whether 40Hz audio and binaural beat 40Hz audio can improve the postoperative cognitive dysfunction seen in patients with aneurysmal subarachnoid hemorrhage. This study is a single-center, prospective, randomized, controlled clinical trial. Patients with aneurysmal subarachnoid hemorrhage were selected and randomized into intervention group (audio adjuvant group) and control group (conventional treatment group). Patients in the intervention group will receive audio therapy after surgery, and patients in the control group will receive usual care. EEG, fMRI and mRS scores were evaluated after 3 months of follow-up.
Perioperative neurocognitive impairment (PND) mainly includes acute postoperative delirium (POD) and persistent postoperative cognitive impairment (POCD), which are common postoperative complications in elderly patients. Perioperative neurocognitive impairment (PND) is attracting increasing attention, but its exact mechanism is still unclear. The diagnosis of PND lacks the gold standard, so it is difficult to determine the incidence rate. At present, the diagnosis is mainly conducted through the scale. Therefore, this study aims to explore the correlation between peripheral blood biomarkers and PND in elderly frail patients undergoing gastrointestinal surgery.
This a two phase project that aims to pilot a new adaptation (Phase 1) of Motivationally Enhanced Compensatory Cognitive Training for Mild Cognitive Impairment (ME-CCT; an originally VA-based cognitive rehabilitation manualized intervention for older adults with MCI, with a focus on the impact of stress on cognitive functioning; that integrates components from the Race Based Stress and Empowerment (RBSE) group for an increased focus on race-based stress and discrimination for racial minority older adults (i.e., RBSEF-CCT-MCI). In a pilot open trial, 75-150 participants will receive group-based intervention for 8 weeks, with 8-10 participants per group. Following the pilot study, the investigators will complete a randomized controlled trial (RCT) (Phase 2) to compare the efficacy of the RBSEF-CCT-MCI with the ME-CCT. In the RCT, 75-150 participants will be randomized into either 1) The active control group, who will complete the original, ME-CCT training program, or 2) The experimental group, who will complete the newly developed RBSE-CCT-MCI. Both research groups will complete the interventions for 8 weeks, with 8-10 participants per group. Hypothesis: Participation in this newly developed/updated intervention (i.e., RBSEF-CCT-MCI) will result in improvements in both (a) subjective and (b) objective cognitive functioning, and (c) self-reported mental health symptoms.
The goal of this prospective observational research with an 8-year follow-up is to study the cognitive changes in the elderly in YuGarden community, Shanghai, China. The main questions it aims to answer are: - incidence of cognitive impairment in community (converting to mild cognitive impairment or Alzheimer's disease) - to build a predictive model for the progression of cognitive impairment
