Filter by:The goal of this clinical trial is to determine if adding avocados to the diet of impacts cognition in 70 older adults, age 65-85, without dementia. We will test for change in functional MRI, cognitive performance, and brain blood flow. Intervention group participants will be asked to consume 1 avocado per day for 12 weeks. Participants in the control group will be asked to continue their normal intake for 12 weeks. Throughout the study, participants will be asked to perform cognitive tests, MRI, blood tests, and questionnaires.
The purpose of this study is to determine if increased blueberry intake helps increase brain antioxidant (glutathione) and cerebral blood flow in older adults.
The purpose of this study is to learn if increased dairy food consumption helps brain health in older adults by protecting nerve cells from damage.
The investigators are planning to recruit approximately 30 study participants aged 50 years and older that will undergo a 4 week attention and emotion regulation intervention. The intervention systematically targets thoughts, emotions and behavior in order to promote quality of life and advance successful brain aging. The investigators will assess the feasibility of recruiting and retaining participants for an attention and emotion regulation intervention. In addition, the investigators will determine the efficacy of the intervention to enhance and promote quality of life, sustained attention, emotions, motivation and cognitive health.
Diffusion MRI employed in functional imaging has the potential to probe directly brain activation instead of blood changes like the BOLD technique. The researchers investigated these rapid synaptic plasticity changes with visual activation followed by BOLD and diffusion functional MRI as well as anatomical (venography, tractography by diffusion) features in young and aged subjects.
Background: - The Coronary Artery Risk Development in Young Adults (CARDIA) study is an investigation of cardiovascular risk factors among African-American and white young adults between 18 and 30 years of age, first recruited in 1985 86 from Birmingham, AL; Chicago, IL; Minneapolis, MN; and Oakland, CA. The study has examined a wide variety of risk factors, including insulin resistance, obesity, and diabetes. Based on 20 years of followup, the data provide evidence of an increase in the prevalence of many cardiovascular risk factors, as well as other factors that may lead to brain disease. To further evaluate these changes, the CARDIA Year 25 Exam will include a brain imaging component to study brain structure and function in a subset of CARDIA participants. Objectives: - To conduct brain magnetic resonance imaging as part of a 25-year followup study on participants in the original CARDIA study of heart disease risk factors in young adults. Eligibility: - Existing CARDIA study participants in the Minneapolis, MN, and Oakland, CA regions. Design: - Participants will be screened with a full medical history and physical examination. - Participants will have an MRI scan at the 25-year followup examination for the CARDIA study. - No additional testing or treatment will be required for this protocol.
