Filter by:This study is examining the effects of growth hormone releasing hormone (GHRH) on mild cognitive impairment (MCI). GHRH will be given at a dose of 1mg/day for 10 weeks to subjects with MCI as well as healthy controls.
Most research on Tai Chi has been done in the area of balance and falls. Studies examining the effects of Tai Chi exercise on cognitive function are sparse especially in the population of MCI. Therefore, the aims of the present study are: 1) to examine the effects of Tai Chi exercise on cognitive function of elderly with MCI, and 2) to investigate the effects of 6-month Tai Chi exercise on serum biomarkers in individuals with MCI.
A six month, placebo-controlled, parallel group project in which MCI participants will receive 30 g/day of a custom-made MCT-based ketogenic supplement or a matching placebo. Uptake of both the brain's fuels - ketones (as 11C-AcAc) and glucose (as FDG) - both before and after the intervention will be assessed by PET (position emission tomography) ; imaging and ketone pharmacokinetic as primary objective as well as fMRI, diffusion MRI and cognition.
T2D and cognitive impairment are two of the most common chronic condition found in persons 60 years and older. Diabetes type 2 increases with age and studies suggest that the diabetes is one of the risk factor for cognitive impairment and dementia. Although there is much recent research showing that diabetics at every age have more cognitive impairment and dementia than non-diabetics, relatively little attention has been paid to the implications of this complication in the management of T2D in terms of screening, prevention, education and treatment adherence. There are now guidelines for periodic evaluation of patients with diabetes as early detection of complications of the disease, but so far there are no similar assessment and monitoring of cognitive function. In this study the investigators examine cognitive function in young diabetic patients (from 20 to 55) using the MoCa test, that allows detection of mild cognitive impairment, and may be carried out during a visit, an annual advisory diabetes clinic.
The Self-Administered Gerocognitive Examination (SAGE) is a valid and reliable cognitive assessment tool used to identify both Mild Cognitive Impairment (MCI) and early dementia. SAGE's self-administered feature, pen and paper format, and four equivalent interchangeable forms allows it to be given in almost any setting, does not require any staff time to administer and makes it practical to rapidly screen large numbers of individuals in the community or in their home.This trial is being conducted to study the validity of SAGE in a digital format (eSAGE) for cognitive screening. The investigators will analyze the data to learn the correlations between eSAGE and gold standard neuropsychological testing designed to differentiate normal cognition from MCI and early dementia. The investigators will also find out whether the paper (SAGE) and electronic (eSAGE) versions of SAGE could be used interchangeably or not. Addendum: The eSAGE was previously validated in an earlier stage of this trial. It was initially designed for tablet use and the exact same test has recently been formatted for smartphone use. This addendum is being conducted to study the validity of the smartphone eSAGE compared to the tablet eSAGE for cognitive screening.
The calcium channel blocker nimodipine dilates cerebral blood vessels and can pass through the blood-brain barrier, providing neuroprotective effects by selectively improving cerebral blood flow and inhibiting neuronal necrosis and apoptosis. Nimodipine significantly inhibited the production of tumor necrosis factor TNF-α and interleukin IL-1β, and also of nitric oxide and prostaglandin E2 from lipopolysaccharide-stimulated microglia. Abnormal cytokine networks are important in the development of nerve cell damage that leads to cognitive impairment.
Permanent and temporary cognitive impairment in the perioperative period is of great importance to patients. Hypoperfusion due to the intraoperative hypotension is often mentioned as a possible cause of postoperative cognitive dysfunction.
There is a dearth of research which takes a multi-compound approach to dietary interventions, in humans, aimed at improving outcome measures of cognition. Animal research in particular points towards fatty acids and flavonoids having a potentiating effect on each other, and possibly even being synergistic. Thus, study products will be administered in the present trial comprising both of these compounds, with a view to investigating their potential effects on cognition in older adults with mild cognitive impairment (MCI) or subjective memory impairment (SMI).
The main objectives for this study are: 1. To investigate novel, non-invasive ocular measurements including optical coherence tomography and eye tracking in a cross-sectional study of participants with various neurodegenerative dementias against standard cognitive assessments and brain imaging measures; and 2. To assess the potential utility of ocular assessments for early detection in the pre-dementia, i.e. the so-called Mild Cognitive Impairment (MCI) stage, across the common neurodegenerative dementia syndromes and, Vascular Cognitive Impairment (VCI) due to small vessel disease (SVD). 3. To determine the prevalence and relevance of amyloid uptake on PET scanning across the dementias most commonly associated with amyloidosis. Specifically we aim to examine correlations with amyloid uptake status in patients symptomatic from the most common proteinopathies (ie amyloid, tau, synuclein) combined in varying degrees with the most common vasculopathies (ie small vessel disease) using multimodal structural and functional imaging, cognitive behavioral, and gait and balance measures, taking into account genetic risk markers (particularly apolipoprotein E genotypes) and fluid biomarkers ( eg cytokines, oxidative stress, lipidomics).
This trial seeks to establish the feasibility of implementing a ketogenic, modified Atkins diet (MAD) to older adults with mild cognitive impairment (MCI) or early Alzheimer's disease (AD) living in the community. A secondary aim is to determine whether adherence to the MAD results in better cognitive test scores than adherence to a non-ketogenic control diet. A final aim is to determine the role of apolipoprotein E (ApoE) genotype in participants' response to the MAD. Participants will be randomly assigned to a 12-week trial of either the MAD or a placebo diet based on the National Institute on Aging's recommendations for senior nutrition.
