Filter by:The purpose of the study is to investigate the associations of the age-related changes in the brain, kidneys and cognitive performance in healthy adults by utilizing multiple anatomic and functional MRI methods along with a battery of cognitive tests.
A variety of non-pharmacological interventions have been used in the management of Alzheimer's disease (AD) and similar cognitive disorders in elderly, yet no therapeutic modality has demonstrated conclusive positive results in terms of effectiveness. Although it is still unknown what triggers AD, recent studies have shown that AD is associated with brain energy depletion, oxidative stress, and mitochondrial dysfunction. Since supplemental molecular hydrogen (H2) supports cell energy production and acts as a highly bioavailable mitochondria-related antioxidant, it may provide an ideal agent to facilitate treatment and perhaps prevention of AD and similar cognitive disorders in elderly. The overall hypothesis to be evaluated in this project is that administration of H2 will positively affect patient-reported outcomes and clinical biomarkers in men and women suffering from AD.
The Vietnam Era Health Retrospective Observational Study (VE-HEROeS) is a national study on the health and well-being of Vietnam Veterans, including Blue Water Navy Veterans, as well as Veterans who served elsewhere during the Vietnam Era (1961-1975), and similarly aged U.S. residents who never served in the military. The investigators will invite approximately 43,000 Vietnam and Vietnam Era Veterans, and approximately 11,000 members of the general U.S. population to participate in VE-HEROeS. These individuals are scientifically selected to participate; the study is not able to accept volunteers. All participants in VE-HEROeS will be asked to fill out a questionnaire on their military service, general health, age-related conditions, health care use, and the health experiences of their children and grandchildren. A smaller group will be asked to provide the investigators with access to some of their medical records. Topics of special focus for the study include cognition, hepatitis C infection, and neurologic conditions.
Evidence shows the positive effects of Brain Health & Wellness classes in younger individuals. The proposed study investigates the usefulness of these classes in older Veterans aged 50-85. We hope to show that such classes can lead to improvements in both thinking skills as well as stress levels.
The mental repetition of movements - or motor imagery (MI) practice - facilitates motor learning. It allows avoiding fatigue that occurs during physical practice; this method is thus particularly interesting for elderly people. Transcranial direct current stimulation (tDCS) is a noninvasive method of neurostimulation during which a low direct current is applied to the brain via electrodes placed on the scalp. This method has been successfully used to enhance motor learning in both young and elderly subjects. The main aim of this study is to assess the impact of MI practice combined with tDCS on the learning of a complex finger sequence, in young and elderly subjects. For that purpose, young and elderly healthy subjects will be randomly assigned to Stimulation and Sham groups. There will thus be a total of four groups: Young Stim, Young Sham, Elderly Stim, and Elderly Sham. All subjects will participate to three training sessions spread over five days, and a retention test one week after the third training session. During training they will mentally repeat a complex finger sequence with the left hand, for 13 min: - Subjects of the Stimulation groups (Young Stim and Elderly Stim) will receive in parallel an anodal tDCS of the primary motor cortex. - Subjects of the Sham groups (Young Sham and Elderly Sham) will receive in parallel a sham tDCS of the primary motor cortex. Immediately before (pretest) and after (posttest) each training session, as well as during the retention test, subjects will repeat the sequence as many times of possible, for 1 min. During these tests (pretests, posttests and retention test) electroencephalographic activity will be recorded to assess the Mu rhythm power.
Deficiency in gonadal hormone has been considered to play a role in ageing related increased incidence of cardiovascular events. But the mechanism has not been fully elucidated. On the other hand, the dramatic increase in gonadotropin level didn't drew much attention when talking about the increased risk of cardiovascular disease during menopausal transition. This study aim to investigate the association between gonadal hormone, gonadotropin and long-term cardiovascular events.
This project develops and tests the use of service robots to track health of the elderly over time. The objectives are to develop a low-cost mobile manipulator capable of a limited set of elder- relevant manipulation tasks (e.g. picking up dropped items). The investigators will visualize and model the use of the service robot during deployments at an elder care facility. Feedback from focus groups with elders and clinicians will inform the necessary engineering innovation.
The purpose of this study is to determine whether specific nutrient supplementation can improve dynamic stability in older adults.
The purpose of the study is to evaluate the beneficial effects of infusions of plasma from young donors using blood biomarkers.
Recent studies show preliminary evidence of HBOT therapeutic effects on angiogenesis, increased tissue blood flow and oxygenation correlated with tissue function. Our primary hypothesis is that HBOT will have beneficial effects on the above mentioned organs associated with aging-related malfunctions due to restored mitochondrial function, mobilization of stem cells and induction of angiogenesis.
