Filter by:This study will investigate the efficacy of a smart home / digital memory notebook (DMN) partnership that will allow for real-time intervention and thereby facilitate acquisition and use of the DMN to support everyday independence. The DMN is an app that is installed on a mobile tablet. The smart home technology discovers and recognizes generalizable activities and provides information about functional status and health-related variables for older adult participants. This study will examine how smart home prompts affect individuals' DMN use, ability to maintain activity routines, and overall wellbeing. Prompts will center on helping users organize and schedule daily activities, record both routine and uncommon events that may need to be remembered, and record activities performed and important associated event information (e.g., when, what, where). Prompting will help to promote everyday functional independence by encouraging frequent and regular notebook use and reducing memory difficulties. The DMN will also help to support functional independence by notifying individuals about appointments or prompting individuals to initiate important activities of daily living (e.g., take medications). This study will also involve a machine learning technique to gain a better understanding of the contexts in which individuals adhere or do not adhere to the prompts. This activity-aware intervention will be deployed in the homes of older adults with memory difficulties, to assess the usability of the technology as well as to evaluate in a naturalistic setting the efficacy of the technology for increasing everyday functional independence and quality of life and decreasing care-partner burden. This contribution is significant because it will demonstrate that intelligent technologies can improve the efficacy of traditional memory rehabilitation techniques, extend functional independence, reduce caregiver burden, and improve quality of life.
The goal of this study is to evaluate the impact of systemic therapy on cognition in older breast cancer patients, explore change in APE, LM and Cognition domains, measure associations between cognitive decline and QOL, and describe how genetic polymorphisms, inflammatory biomarkers, sleep and physical measures moderate cognitive outcomes. This study is being done nationally, with recruiting sites at Georgetown University, Montgomery General Hospital, Virginia Cancer Specialists, Washington Hospital Center, Reston Breast Care Specialists, Memorial Sloan-Kettering, Moffitt Cancer Center, City of Hope National Medical Center, Hackensack University Medical Center, Indiana University and University of California, Los Angeles.
Alzheimer disease (AD) is a dementing illness characterized by progressive neuronal degeneration, gliosis, and the accumulation of intracellular inclusions and extracellular deposits of amyloid in discrete regions of the basal forebrain, hippocampus, and the association cortices. Mild cognitive impairment (MCI) refers to individuals with cognitive impairment (often memory loss) that fails to meet clinical criteria for AD or another dementing illness.
This study evaluates the efficacy and mechanism of acupuncture treatment in patients with subjective cognitive decline. Half of patients will receive acupuncture treatment for 12 weeks, while the other half will receive sham acupuncture treatment for 12 weeks .
To study the correlation of POCD with olfactory function. To explore whether enhanced olfactory stimuli can reduce the risk of POCD as a preventive strategy.
Diabetes has become important risk factors for threatening human life and health. Studies have shown that chronic hyperglycemia lead to microvascular brain injury. The more common types of dementia are Alzheimer's disease (AD). Cognitive dysfunction is a precursor to Alzheimer's disease. Mild cognitive impairment (MCI) is a cognitive impairment between normal aging and dementia, mainly manifested as memory impairment, especially episode memory defects, but also named obstacles, but the overall cognitive function is normal, daily life ability is normal. Studies have shown that middle-aged diabetic patients' cognitive ability will decline by about 19% in 20 years compared to people without diabetes. Sulfur amino acid is the indispensable amino acid in mammals, and its metabolites include Taurine, Hydrogen sulfide (H2S) and sulfur dioxide (SO2). Taurine was first isolated more than 150 years ago from ox (Taurus) bile. Although the taurine can be synthesized in vivo by cysteine in the presence of cysteine dioxygenase, it is mainly acquired from dietary sources, such as eggs, meat, and seafood. H2S is a biologically relevant mediator and plays potential roles in several physiological processes and disease states in the body. H2S is synthesized from 2 sulfur-containing amino acids, l-cysteine andl-methionine, by the 3 enzymes,cystathionine-γ-lyase (CSE), cystathionine-β-synthetase(CBS), and3-mercaptopyruvate sulfurtransferase (3-MST). Previous studies have demonstrated that Taurine and H2S may play important roles in the development of themicroangiopathy and lower extremity arterial occlusive.
Cognition encompasses memory, attention, language and other brain capacities that are necessary for good quality of life and independence. Age-related cognitive decline starts at the third decade of life and in some cases can start to impact daily functioning in the late forties. Dementia is the most devastating consequence associated with age-related cognitive decline. Recent studies indicate that improving cognition by means of intensive computerized brain training can mitigate some aspects of agerelated cognitive decline, and may even have a role in preventing or delaying dementia onset. Critically, the capacity of a given individual to improve their cognitive performance after training is fundamentally related to engagement with the exercises. Currently, little is known about how to apply intensive computerized cognitive training effectively in the health system, ensuring engagement and best progress. This project aims to tackle this challenge by developing, applying and testing personalized approaches to implement cognitive training in daily life of older adults that were recently evaluated at Memory Clinics and their care partners. The community readiness approach will be implemented using semi-structured interviews, conducted with subjects that may be interested in cognitive training, key informant, and key stakeholders. Using this information, the investigators will design an individualized training program and follow up its application in a feasibility trial. Twenty participants, recently evaluated at different Memory Clinics in Ireland, will be recruited, interviewed and invited to engage, over the ensuing 2 to 3 months, in computerized cognitive training. Subjects will be assessed after completion of the intervention for training adherence and individual gains on the computerized exercises. In order to gain insight about regional specificities of the approach the investigators will perform a parallel project using the same methodology in Brazil. This project is expected to inform the future implementation of cognitive training in public health policies for older adults.
The purpose of this study is to investigate whether preoperative pain is the risk factor of POCD in elder patients.
Many patients with primary brain tumors experience cognitive deficits and cognitive rehabilitation programs aim to alleviate these deficits.The cognitive rehabilitation program developed by the investigators proved effective in a large randomized controlled trial (RCT). To increase its accessibility, it was converted into the iPad-based cognitive rehabilitation program ReMind, which incorporates psychoeducation, strategy training and retraining. A pilot study and a randomized controlled trial are conducted, to evaluate the feasibility of the use of the program and the efficacy of the program in brain tumor patients after resective surgery.
The investigators aim to use the new PET radioligand, 18F-MK-6240, to detect tau pathology in cognitive healthy and mild cognitive impairment (MCI) elders. The investigators will then examine the interactions between differential tau burden and performance on cognitive tasks, functional magnetic resonance imaging (fMRI) neural activation patterns, and other cognitive and behavioral measures. By investigating these relationships, the investigators hope to understand the cognitive and behavioral outcomes of tau deposition found in specific brain regions in cognitively normal/mildly cognitively impaired adults. Furthermore, the study aims to examine how the presence of tau may contribute to the risk of subsequent cognitive decline, neurodegeneration, and dementia.
