Filter by: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.
The current study will examine the use of a mobile electronic application used to deliver cognitive rehabilitation to patients with mild cognitive impairment due (MCI) due to Alzheimer's disease (AD), and patients with mild AD. Patients will be given a specific cognitive rehabilitation program on their mobile device (iPad) with specific tasks for them to complete. The goal of this study is to determine if a) patients are able to use and adhere to a cognitive rehabilitation program delivered to their mobile device and b) to determine if patients can improve their language, attention, and memory by completing cognitive rehabilitation tasks assigned to them.
This pilot clinical trial studies how well a mindfulness-based stress reduction (MBSR) intervention works in reducing anxiety in patients who have undergone treatment for gynecologic cancer but no longer have any sign of disease. Gynecologic cancer is cancer of the female reproductive tract, which includes the cervix, endometrium, fallopian tubes, ovaries, uterus, and vagina. Side effects from treatment for these cancers may include anxiety, fatigue, depression, and sexual function changes. Mindfulness training uses meditation and yoga to help patients focus on breathing, bodily sensations, and mental awareness. This may help decrease patients' stress and anxiety and improve their quality of life, and may also help their immune system.
The purpose of this study is to determine if a high dose of DHA begun prior to and continued during neo-adjuvant chemotherapy (chemotherapy given prior to surgery) is likely to prevent or lessen chemotherapy induced cognitive dysfunction.
The main goal of this project is to identify and remediate the cognitive difficulties, including processing speed and attention deficits in individuals who have undergone chemotherapy treatment. Recent research has demonstrated objective cognitive deficits following chemotherapy and that it is not an emotional reaction to the cancer diagnosis as it was once considered. There are a large number of woman diagnosed and treated for breast cancer that experience chemotherapy induced cognitive deficits. Subjects who participate in the study will be evaluated for cognitive abilities prior to chemotherapy treatment and after completion of chemotherapy. Participants will then have the option to participate in the second phase of the study, which involves the use of a computer-based Brain Fitness Program for 12 weeks. This is followed by another cognitive evaluation.
This study aims to investigate and compare the intervention effects of combining exercise and cognitive training (either sequentially or simultaneously in a dual-task paradigm) in elderly with mild cognitive impairment. The investigators hypothesize that (1) both sequential and dual-task training can induce greater improvements in the outcome measures than single mode of training; (2) the improvement in cognitive functions and other outcomes may differ between the groups.
Cognitive dysfunction is a highly persistent, pervasive and progressive abnormality in young adults (i.e., 18-65 years) with MDD. It has also been shown that among adults with MDD who are gainfully employed, measures of cognition are a greater determinant of overall workplace performance than is total depression symptom severity. Several lines of evidence indicate that cognitive deficits that persist between episodes of depression are critical determinants of functional recovery in the workplace. The functional implications associated with cognitive impairment provide the impetus for systematic evaluation, measurement and assessment of the domains of cognition expected to be impaired in this patient population. To date, no measurement tool has been sufficiently validated and/or determined to be sensitive to the cognitive deficits in younger adults with MDD. Major limitations of available comprehensive psychometric tools include relative lack of availability, cost, lack of access to most healthcare providers, and above all else, the lengthy time to administer. Moreover, the need for a psychometrist to interpret the results adds to the complexity and the costliness of such an endeavor. It is imperative that any tool recommended for clinical utility be aligned with the busy nature of a high-volume clinical practice. The ideal gold standard tool for assessing the presence of cognitive dysfunction in MDD in the clinical environment should include, but not be limited to, features such as good conceptual coverage of cognitive domains affected in MDD, good sensitivity and reliability, and it should be relatively uninfluenced by culture effects and practice effects. The tool would also need to be brief, easy to administer and interpret, and complement busy clinical practice. This study is designed to validate a brief user-friendly tool capable of detecting deficit in cognitive performance among adults with MDD. Data will be gathered with the aim to determine whether the proposed tool identifies cognitive deficits in adults with MDD and differentiates the clinical MDD population from healthy controls. It is anticipated that the THINC-it tool will be free of charge and downloadable from the THINC-it website for use in the primary care and specialty setting. The THINC-it tool will be accessible via computers/tablets, will take 20 minutes to self-administer in a clinical setting, and the performance results will be immediately available.
