Active clinical trials for "Cognitive Dysfunction"

The current study will test the effectiveness of a computerized cognitive training program on auditory memory and attention in patients with mild cognitive impairment. Practice effects will also be examined as a moderator of treatment response.

A pilot randomized clinical trial was conducted in a random sample of 120 non-demented Chinese elders (ages 60-79) living in a defined community in Shanghai, China to compare the effects of interventions (fast walking, Tai Chi, group intellectual discussion) to no intervention with respect to change in cognition and whole brain volume determined by repeated neuropsychological batteries and MRI scans. Aims included determining the feasibility of recruiting and retaining a random sample of people age 60+ for such a trial as well as collection of preliminary data on the efficacy of the interventions. The long-term goal of this research program is to determine whether sustained physical and/or mental exercise interventions are efficacious in delaying the onset of dementia and to understand the role and mechanisms of brain growth in this process.

This study will examine the hypothesis that changes in the cognition (i.e. thinking and memory) after anesthesia and surgery are correlated with changes in markers of Alzheimers Disease in the fluid around the brain and spinal cord (i.e. cerebrospinal fluid, or CSF), and/or changes in brain connectivity. The investigators will also examine whether different types of anesthesia have different effects on these CSF markers of Alzheimers disease, or different effects on thinking and memory after anesthesia and surgery, or differential effects on the correlation between cognitive changes and CSF marker changes.

This will be a systematic investigation of the role of walnuts in preventing or slowing age related cognitive decline and age related macular degeneration. 700 subjects will be recruited between 2 sites, Loma Linda University in California, USA and Hospital Clinic in Barcelona, Spain. Participants will be randomly assigned to either the walnut group or the control group for a 2 year intervention. Baseline and annual data will be collected and analyzed.

The purpose of the study is to investigate, in healthy middle age subjects, effects of whole grain rye on cognitive functions, mood, and cardiovasculair risk markers

The purpose of this study is to determine whether the researchers can help people change the amount of time they spend in sitting activities and whether this change might improve health outcomes.

The study aims to randomize 320 (160 Caucasian, 160 African American) socially isolated adults 75+ years old (50:50 split between those with normal cognition and mild cognitive impairment (MCI)) recruited from the community to either the Video Chat Group or the Control Group. The participants in the Video Chat Group will receive a computer and internet service for the duration of the study, which they will use to video chat with study staff for 30 minutes/day 4x/week for 6 months (high dose), and then 2x/week for an additional 6 months (maintenance dose). The efficacy examination of the maintenance dose is limited to an exploratory aim. Both intervention and control groups will have a brief (about 10 minutes) telephone check-in with study staff once per week. In-home testing will occur at Baseline and 6 months. A sub-sample of participants** will be assessed at 12 months (exploratory) after additional 6 months of maintenance dose. All participants at OHSU will have their medication compliance tracked using an electronic medication monitoring device and participants at both OHSU and UM will have MRIs at Baseline and 6 months, if they are able to safely receive MRIs. Participants at both sites will contribute saliva for genetic testing (optional consent), and all video chat and neuropsychological assessment sessions will be recorded for speech and language analysis (consent required for participation).

Tart cherries are a rich source of antioxidants. Studies have shown that tart cherries exert anti-oxidative and anti-inflammatory properties. The purpose of this study is to learn about the effects of drinking tart cherry juice on cardiovascular and cognitive health.

The study aimed at assessing whether the guidelines from the European project FOCUS had an effect on adherence to a physical activity program in older women. The program consisted of two 12-week periods, in which women followed a set of pre-specified exercises (1 hour, twice per week). The first period was supervised by a monitor while the second was autonomous. Support groups, in which the contact between participants was established through information and communication technologies (social-network through the mobile phone), were set up to maintain engagement between participants. Women were randomized to three arms consisting of 2 intervention groups, with and without the FOCUS guidelines, and a sedentary control. Secondary outcomes included a battery of dimensions affecting physical performance, psychological status, and quality of life.

Nine-weeks double-blind, randomized, placebo-controlled, parallel-arm superiority study. The aim of this study is to evaluate the influence of a mix of four bioactive compounds - bacopa, lycopene, astaxanthin and vitamin B12 - on cognitive performance, mood state and well-being in subjects aged ≥ 60 years with no evidence of cognitive dysfunction. The primary objective of the study is to evaluate the changes in Trial Making Test (TMT) scores from baseline (V2) to 8 weeks of treatment (V4), analyzed in the following hierarchical order: TMT-B, TMT-A and TMT B-A. Secondary objectives of this study are to evaluate changes from baseline (V2) to 8 weeks of treatment (V4) in Verbal Fluency Test (VFT) score, Montreal Cognitive Assessment (MoCA) score, Mini Mental State Examination (MMSE) score, Rey Auditory Verbal Learning Test (AVLT), psychological well-being as assessed by General Health Questionnaire (GHQ-12), mood states as assessed by the Profile of Mood Stated (POMS), sexual satisfaction as evaluated by the New Sexual Satisfaction Scale (NSSS). Changes of metabolic parameters from baseline (V2) to 4 weeks of treatment (V3) and from baseline (V2) to 8 weeks of treatment (V4) will be also evaluated as secondary objectives (glucose, insulin, Homeostatic Model Assessment for Insulin Resistance (HOMA-IR), total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, uric acid). Changes of plasma markers of oxidative stress from baseline (V2) to 4 weeks of treatment (V3) and from baseline (V2) to 8 weeks of treatment (V4) will be evaluated as secondary objectives (8-iso-Prostaglandin F2alpha, Plasma malondialdehyde). Finally the safety and tolerability of the study product will be assessed.
