Active clinical trials for "Cognitive Dysfunction"

Whether enough time and high-quality cognitive training will reduce the incidence of postoperative cognitive dysfunction after cardiac surgery.

This study evaluates the effects of 3 years-Tai Chi exercise intervention on cognitive function in subjects with subjective cognitive impairment (SCI). Participants will be randomized into the Tai chi training group and the control group.

The objective of this observational study is to provide basic data for predicting and analyzing the occurrence and causes of delayed cognitive impairment, an important factor in the quality of life, among discharged patients who have received targeted temperature management therapy and experienced favorable neurological outcomes after out-of-hospital cardiac arrest. The main questions it aims to answer are: Can we identify abnormal areas in the brains of patients with delayed cognitive impairment using Brain MRI or positron emission tomography (PET) imaging? Is it possible to predict delayed cognitive impairment using biomarkers?

In Canada, 1,700,000 adults are at risk of dementia, half of them with MCI, representing one of the largest groups at risk for an incurable disease. Epidemiological evidence suggests up to 40% of dementia cases might be preventable by targeting modifiable lifestyle/cardiovascular factors.Given that current treatments cannot modify the disease, prevention is critical. SYNERGIC-2 offers a "personalized tailored intervention" that combines physical and cognitive training, sleep, diet, and vascular-metabolic interventions in individuals with MCI to synergistically enhance their overall brain health including cognition and contributes to maintaining their independence. Importantly, interventions will be provided at home using an existing virtual platform reducing delivery complexity and expanding the accessibility to a wider population, thus decreasing potential inequities. Improving older adults' brain health and achieving even a modest two-year dementia incidence delay will have a projected saving of $218 Billion in Canada's healthcare system over 30 years.

Postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) occur in 11-51% of patients after surgery, and its prevalence increases with age. The occurrence of delirium is associated with increased morbidity and mortality, prolonged hospital stay, worse functional recovery. Orthopedic procedures and specifically joint replacements have been considered as a major risk for development of chronic postsurgical pain (CPSP). Approximately 13-44% of patients will develop CPSP after knee or hip arthOpioid abuseroplasty. CPSP may cause the discomfort, distress, disability and opioid abuse. Mounting evidence has revealed that inflammation triggered by surgical trauma plays a key role in POD, POCD and CPSP. Recent studies found that vagus nerve stimulation showed the suppression of inflammation. In this study, the effect of perioperative transauricular vagus nerve stimulation on the prognosis of patients undergoing arthroplasty will be investigated, providing potential solutions for the prevention and treatment of postoperative cognitive dysfunction, postoperative delirium and chronic postsurgical pain.

PROACTS is a Phase I/II study to assess the efficacy of AARP Staying Sharp online health program, focusing on the health of non-professional home-based caregivers of persons with Alzheimer's disease and related dementias (ADRD). PROACTS has three aims. Aim 1&2 is an one-time survey study to evaluate the current uptake and utilization of Staying Sharp among caregivers. Aim 3 is a single-group intervention to assess how Staying Sharp may maintain health and function for caregivers of persons with ADRD. Participants will participate in a 4-month program with a 4-month follow-up. Aim 1&2: Characterize caregivers of persons with ADRD using Staying Sharp and evaluate user experiences of Staying Sharp. Aim 3: Establish preliminary efficacy of Staying Sharp program.

Endoscopic retrograde cholangiopancreatography (ERCP) is an interventional endoscopy procedure utilized in the therapeutic management of pancreatobiliary diseases including gallstones, bile duct strictures, leaks and infections, pancreatitis, and cancers of the bile duct or pancreas. ERCP is classified as a high risk procedure. Potential adverse events directly attributable to the technical aspects of ERCP include pancreatitis, hemorrhage, infection, and bowel wall perforation. Other potential adverse events of ERCP may be less apparent and/or unknown, such as risk of neurocognitive dysfunction. Overall, neurocognitive dysfunction after medical procedures impacts quality of life, functional disability, depression, and caregiver and societal burden. The prevalence of postoperative neurocognitive dysfunction and disability following interventional endoscopy procedures such as ERCP has not been reported. This prospective observational study is designed to assess the prevalence of cognitive impairment and functional disability after ERCP and endoscopic ultrasound (EUS) procedures in older patients, and to assess whether specific patient and/or procedural factors are associated with increased risk of adverse outcomes.

Participants enrolled at the Alzheimer's Disease Research Center (ADRC) at Wake Forest School of Medicine will be invited to take part in this study. The purpose of this study is to identify and measure the amount of a protein called amyloid in the brain.It is thought that the build up of amyloid may be related to the development of Alzheimer's disease.

The purpose of this study is based on the Flutemetamol-PET senile plaque imaging to investigate the peripheral blood biochemical and brain MRI imaging biomarkers and to research completely independent intellectual property rights neuropsychological test tool for the MCI due to AD. At the same time, the investigators will study the efficacy and safety of early treatment of MCI due to AD by Huperzine A in 52 weeks.

This protocol study aims to evaluate the efficacy of the MOVI-ageing intervention, a complex home-based eHealth intervention of cognitive-demanding exercise for the elderly, in improving: global cognitive function and basic cognitive functions and cardiorespiratory and muscular fitness. In addition, this sudy aims to evaluate the efficacy of the MOVI-ageing intervention, in improving: body composition (waist circumference and fat percentage), blood pressure, and health-related quality of life. The MOVI-ageing project has been designed in three phases comprising: i) a tool development study; ii) a 12-week randomized efficacy/feasibility trial of the intervention; and iii), a large-scale implementation phase with a 12-week randomized trial. The investigators will use a qualitative approach to improve the plataform design with the users perspective. Participants will have access to a platform where participants will be able to view videos of cognitively demanding physical exercise programs. The videos will be directed by an avatar and the research staff will be able to know the degree of compliance with the program and the correct execution of the program through the use of Physio Galenus technology. The platform will have information on how to be more active, and chat lines to communicate with the research group. Participants will receive feedback on their compliance with the routines and reinforcement messages.
