Filter by:Due to demographic changes that have resulted in an aging population, the role of caregiver of an older adult has become very important in recent years. While numerous programs have been designed to lighten the caregiver's physical and emotional burden, fewer programs train caregivers to improve skills and level of independence in the person they care for. The objectives of this research study were to assess the benefits of a caregiver training program on the cognitive and functional status of older adults, as well as to compare the effects of this program according to type of caregiver (professional caregiver vs. family caregiver). Methods: The sample was composed of 160 older adults: a) 100 received care from caregivers who had taken the training program (treatment group), of which 60 were professional caregivers and 40 were family caregivers; and b) 60 received care from caregivers who had not taken the program (control group). In order to evaluate program effects on cognitive and functional status, we used both direct measures (MMSE, CAPE and EuroQol) and caregiver reports (Barthel and RMPBC).
Heart failure is a prevalent and serious public health concern with the growing aging population. Patients with heart failure often experience attention impairment that decreases their ability to perform self-care and diminishes their health-related quality of life. In past studies, 15 - 27% of heart failure patients had attention impairment. Attention is fundamental to human activities including self-care management of heart failure. However, cognitive interventions focusing on attention are scarce in heart failure literature. This study focuses on developing a novel cognitive intervention specifically targeting improved attention and testing its efficacy on improving attention, self-care, and health-related quality of life. The investigators in this study are asking the following 3 questions: 1) does the newly developed cognitive intervention using immersive virtual reality technology (Nature-VR) improve attention compared with the control condition (Urban-VR)?; 2) does Nature-VR intervention improve HF self-care and health-related quality of life compared with Urban-VR control condition?; and 3) are selected biological factors associated with attention function in HF? The virtual reality-based cognitive intervention (Nature-VR) can be an efficacious intervention for the patients to use and enjoy without burdening already reduced attention. This study has great potential to improve attention and prevent attention impairment, thereby leading to healthier lives among heart failure patients.
Aging-related cognitive decline may be affected by brain cholesterol and the health of cell membranes. Certain nutritional supplements have been proposed to support membrane health, and there is increasing interest in plasmalogens and Omega-3 derived oil supplements to support brain health among older adults. The product being investigated in this study is the ProdromeNeuro Omega 3 oil nutritional supplement. This product contains naturally occurring fatty acids in higher concentrations than similar products that are commercially available. The purpose of this research study is to better understand the effects of ProdromeNeuro Omega-3 nutritional supplementation among subjects with age-related cognitive decline.
This study will characterize tau tracer retention by Positron Emission Tomography (PET) as a function of amyloid levels transversally and longitudinally.
The purpose of this research study is to learn whether it is possible and useful for caregivers to report behavioral or psychological symptoms of people with mild memory problems or Alzheimer's disease through a smartphone mobile application. The investigators believe that monitoring these symptoms and having a tool, like a mobile application, can provide quicker accessibility to the patient's clinical care team, which could improve care for patients and caregivers. These types of symptoms found in patients with mild memory problems or Alzheimer's disease are any type of psychiatric symptoms or abnormal behaviors one might develop as the result of these brain illnesses. Examples of psychological and behavioral symptoms are depression, anxiety, insomnia, irritability, agitation, and hallucinations. These symptoms differ from regular psychiatric symptoms, because they are caused by mild memory problems or Alzheimer's disease (AD). These symptoms can cause a lot of distress for patients and caregivers, and can lead to greater use of healthcare services.
The challenge of new recommendations and better adapted practices is pushing to operate patients who are getting older and more fragile. In this context, there is an inevitable increase in the risks associated with care and in particular perioperative neurological complications, of which postoperative cognitive dysfunction (POCD) is the most common. The interest of perioperative cerebral monitoring and in particular electroencephalography (EEG) to reduce neurological and cognitive damage in surgery has been the subject of abundant research and corresponds to a crucial issue. From the literature and preliminary results obtained in our clinical research unit, it appears that there is also a relationship between certain characteristics of the peroperative EEG (signal strength and burst suppression) and the occurrence of postoperative cognitive dysfunction (PCOD). In this context, quantitative analysis of the preoperative sleep EEG and the EEG obtained during general anesthesia could allow the identification of a simple to use biomarker of susceptibility or fragility. To our knowledge, there is no preoperative evaluation strategy using EEG analysis to detect a predisposition to POCD. The main goal of this observational clinical study is to extend the traditional use of per-operative EEG with pre-operative and post-operative sleep EEG for the detection and prediction of early post-operative cognitive dysfunction.
The current study will examine the impact of frequent social interaction through communication technologies during COVID-19 pandemic in the cognitive status of socially-isolated older adults with and without cognitive impairment. Patients will take place in an experimental crossover study, participants will complete one month of an intervention and one month of as passive control. The goal of this study is to determine: A.) if frequent social interaction through ICT during COVID-19 pandemic will have a significant positive impact in cognitive performance on testing, and B.) how social isolation and cognitive status influence misconceptions around the current pandemic.
The primary purpose of this two-part study was to evaluate the safety and tolerability of SAGE-718 and its effects on cognitive, neuropsychiatric, and motor symptoms in participants with Parkinson's disease mild cognitive impairment (PD-MCI).
The investigators will aim enroll participants into our study within 3-6 months after their parent study visit so the investigators can utilize some key data points (e.g. PD-MCI diagnosis, rs-fcMRI data) from that study. PD participants will participate in a single-blind RCT with two treatment arms: process training and strategy training (Fig 4). They will complete pre-training assessment (Pre), be randomized to treatment arm (1:1 ratio stratified by sex), and then complete 8 training sessions over an 8-week period. They will return within 1 week for post-training assessment (Post) and then will complete Follow-up (FU) assessments via web or mailed survey 3 and 6 months after training ends. They will complete a 12mo FU assessment in person in conjunction with their annual parent study visit. HC participants will complete prospective memory assessment at one time point coinciding with (or within 3-6 months of) their parent study visit to determine whether any relationships observed between rs-fcMRI data and prospective memory are specific to PD.
This is a randomized, controlled pilot study to evaluate the efficacy of "ASCEND-I" (A Strategy and Computer-based intervention to ENhance Daily cognitive functioning after stroke - Inpatient), an inpatient intervention that combines computer-based cognitive training and coaching of cognitive strategies to improve working memory (WM) and related executive functions in individuals with stroke. The investigators hypothesize that relative to an "enhanced usual care" control condition, ASCEND will be associated with improvements in WM. The investigators also hypothesize that measures of baseline brain connectivity (assessed via participants' routine clinical magnetic resonance imaging scans) will predict response to ASCEND-I.
