Filter by:This observational cohort study in healthy volunteers establishes normative data for the German version of the Montreal Cognitive Assessment (MoCA) and investigates the possible impacts of demographics on the MoCA total score.
The ACHIEVE study will be a randomized controlled trial nested within the infrastructure of the Atherosclerosis Risk in Communities (ARIC) study. We plan to enroll 850 70-84 year-old cognitively normal older adults with hearing loss, who will be randomized 1:1 to the hearing intervention (hearing needs assessment, fitting of hearing devices, education/counseling) or successful aging health education intervention (individual sessions with a health educator covering healthy aging topics). Post-baseline, participants will be followed semi-annually for 3 years.
This is a pilot randomized controlled clinical trial is designed to investigate whether the Multicultural Healthy Diet (MHD), an anti-Inflammatory diet tailored to a multi-cultural population, can improve cognitive functioning in a middle aged (40-65 yr) urban population in Bronx, New York compared to a usual diet.
Every year, approximately 9,000 Parkinson disease (PD) patients undergo deep brain stimulator (DBS) placement into the subthalamic nucleus (STN-DBS). Studies suggest that PD patients with mutations in the glucocerebrosidase (GBA) gene are at high risk for cognitive impairment and approximately 10-17% of subjects undergoing DBS carry GBA mutations. There may be an interaction between STN-DBS, which also impairs cognitive function, and GBA, resulting in worsened cognitive function. This project will 1) determine the relationship between GBA mutation status and post-operative STN-DBS cognitive function, 2) broaden genotype-phenotype relationships of GBA mutation carriers and 3) provide scientific knowledge regarding the longitudinal cognitive effects of DBS in GBA mutation carriers through repeated neuropsychological testing.
The study will provide insight into how lifestyle-related interventions, specifically nutrition and exercise can impact the health of older women. The study uses a unique combination of interventions and encapsulates overall health outcomes by measuring both mobility and cognitive function. The study examines the effects of a combined omega-3 polyunsaturated fatty acid (PUFA) and multi-nutrient supplement on measures of mobility and cognition in women aged 60 years and above. Volunteers for the study will be randomly assigned to one of four groups which are as follows: - Omega-3 PUFA multi-nutrient supplement and aerobic exercise - Omega-3 PUFA multi-nutrient supplement and no exercise - Placebo supplement and aerobic exercise - Placebo supplement and no exercise Volunteers undertake the dietary supplementation for a period of 24 weeks. The active dietary supplement contains a daily dosage of 1 g docosahexaenoic acid, 160 mg eicosapentaenoic acid, 240 mg Ginkgo biloba, 60 mg phosphatidylserine, 20 mg d-α tocopherol, 1 mg folic acid, and 20 µg vitamin B12. The placebo supplement contains an iso-calorific oil blend that is typical of the current UK diet. The aerobic exercise consists of two classes per week the final 12 weeks of the study on stationary spinning exercise bikes. Volunteers attend testing at the beginning and after 24 weeks. Verbal memory, spatial working memory, executive function and processing speed are assessed via a battery of cognitive tests. Mobility testing comprises three walking tests, some under single and dual task paradigms, as well as the five times sit to stand test, a measure of dynamic balance and functional mobility. Volunteers also provide two blood samples, one for fatty acids analysis and the other serum homocysteine levels. Participants also complete health-related quality of life questionnaire, the short form 36 (SF36) questionnaire, food diary and food frequency questionnaire.
The investigators are interested in how attentional filter training/ distractor inhibition training could influence cognitive functions like working memory, executive control, problem solving, decision making and attentional control.
The proposed research is clinical study evaluating the therapeutic benefits of curcumin on vascular function in patients with chronic kidney disease (CKD). The study aims to establish that curcumin will improve endothelial function and reduce large artery stiffness by reducing oxidative stress and in conjunction with lowering markers of inflammation and oxidative stress. In addition, the study will evaluate the potential benefit of curcumin on cognitive function in patients with CKD.
To determine associations between dietary factors and risk of major chronic diseases and their risk factors
The purpose of this study is to evaluate if systematic cognitive training can improve cognitive performance in participants (55 and older) with memory loss. This study will evaluate the effects of Computerized Cognitive Training (CCT) for improvement in everyday cognitive and function status, in addition to long-term changes in brain networks over an 18-month period. Although there is no distribution of medication for this study, participants are required to have an at-home computer.
The Alpha Omega Cohort is a prospective study of 4,837 state-of-the-art drug-treated Dutch patients aged 60-80 years who had a clinically diagnosed myocardial infarction up to 10 years before enrolment. During the first 40 months of follow-up, patients took part in an experimental study of low doses n-3 fatty acids (Alpha Omega Trial, ClinicalTrials.gov NCT00127452). At baseline (2002-2006), data on medical history, medication use, diet, lifestyle and other factors were collected by means of questionnaires. Patients were physically examined by trained research nurses and blood samples were obtained. Follow-up for vital status and cause-specific mortality is ongoing. The trial was approved by a central medical ethics committee (Haga Hospital, The Hague, The Netherlands) and all patients provided written informed consent.
