Filter by:Older adults with subjective cognitive decline (SCD) are at high risk of developing dementia and frequently experience subclinical symptoms (e.g., anxiety, depression) which are themselves associated with dementia and cognitive decline risk. To date, the lack of effective disease-modifying treatments, along with the reliable identification of modifiable lifestyle risk factors (e.g., cognitive activity, dietary habits, physical exercise), have led to growing interest to invest in non-pharmacological interventions that may reduce the prevalence and incidence of dementia and cognitive decline in older adults. In this framework, the aim of this project is to evaluate the efficacy of an Immersive Virtual Reality (IVR) and telemedicine-based multi-component intervention, combining cognitive training and a health and lifestyle education program, for preventing cognitive decline and dementia in at-risk individuals (i.e., SCD). For this purpose, a randomized, double-blinded controlled trial (RCT) will be conducted on seventy-five eligible individuals with SCD, who will be randomly assigned to one of three conditions: (a) multi-component intervention (MC-I), including SCD-tailored cognitive IVR training plus a health and lifestyle education program, (b) cognitive-only intervention (CO-I), including the SCD-tailored cognitive IVR training plus an active control for the education program, and (c) active control intervention (AC-I) for both cognitive training and education program. Intervention will be provided in 20 at-home sessions (4 sessions/week, each lasting about 30 minutes) over a period of 5 weeks. Outcome measures include clinical, neuropsychological, behavioural and neuroimaging data that will be collected before and immediately after intervention in order to detect potentially intervention-induced changes in objective cognitive functioning (primary outcome), subjective cognitive functioning, mood, quality of life and brain connectivity (secondary outcome). Users' compliance with IVR and telemedicine approach will be also evaluated, as well as individuals' factors affecting training efficacy.
Dementia is a syndrome characterized by progressive global cognitive impairment that impairs occupational, family, or social functioning. It detrimentally affects personal health and quality of life, imposing significant medical economy, social and psychological burden on the countries and the patients' family. The internationally renowned dementia cohort includes the DIAN that focused on genetics studies, the ADNI cohort featuring imaging and the FINGERS cohort focused on risk factor intervention, etc. Establishing standardized and shared longitudinal follow-up dementia cohorts and clinical database is an essential challenge for constructing dementia cohort in China. Moreover, there is a lack of large-scale prospective longitudinal follow-up cohorts within the Chinese population that cover subjective cognitive decline (SCD) to explore biomarkers with diagnostic and early warning value for different kinds of dementia and pre-dementia stages. The study will rely on the dementia cohort based on Chinese population to explore the biological phenotype characteristics of the pre-dementia stage and different dementia subtypes, and observe the dynamic change rules of the dementia cohort vertically, so as to foster early intervention and improve prognosis for individuals with dementia.
The purpose of this study is to develop and test CarePair, a web-based needs assessment and service referral platform for family caregivers of persons with dementia designed to alleviate stress and promote psychosocial well being. The main aims of this study are: - To evaluate the feasibility and acceptability of the CarePair web application. - To explore the potential for the CarePair web-application to reduce feelings of depression and burden, and improve caregivers' feelings of self-efficacy. Caregiver participants will be asked to log in and test the CarePair web application and complete study activities for a three-month duration. Researchers will compare the intervention group to an attention control comparator to see if application use is associated with improved psychosocial outcomes at follow-up.
A 12-month cluster-randomized controlled trial designed to test the effect of the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) diet education on the rate of cognitive change and several other secondary outcomes in 1200 adults aged 40-69 years.
The aim of this proposal is to identify immune biomarkers, genetic risk, and the clinical consequences of low count monoclonal B-cell lymphocytosis (LC MBL), a common premalignant condition affecting up to 17% of European adults age>40. LC MBL is a precursor to chronic lymphocytic leukemia (CLL), characterized by a circulating population of clonal B-cells. It is relatively understudied, despite emerging evidence of clinical consequences such as increased risk for life-threatening infections and lymphoid malignancies. Studies reported that male sex, age, family history of CLL, and CLL-susceptibility genetic loci were associated with LC MBL risk. These findings were reported in European ancestry individuals and have not been generalized to other thnicities. This study will provide this missing knowledge using a unique multi-ethnic Israeli population of Jews and Arabs that have one of the highest and lowest age-standardized incidence rates of CLL in the world, respectively, and characterized with different genetic backgrounds.
The number of older migrants with cognitive impairment and dementia living in Italy and attending national healthcare services is rapidly increasing. There is a need to develop diversity-sensitive policies and practices to include migrants and people with different cultural values in the public health response to dementia.
This study aims to assess the efficacy of telephone-coached graphic narrative bibliotherapy in improving dementia caregiver depressive symptoms compared with the booklet group.
Up to 25% of intensive care unit (ICU) survivors experience cognitive impairment comparable in severity to mild Alzheimer's disease and related dementias after hospital discharge. Older ICU survivors (ages 60 and older) are at highest risk for delirium and subsequent cognitive impairment, which contribute to higher risk for cognitive decline related to Alzheimer's disease and related dementias. Sleep and activity are essential for recovery from critical illness, yet ICU survivors experience both sleep deficiency and profound inactivity. About 75-80% of ICU patients experience circadian dysrhythmia, which contributes to cognitive decline and increases likelihood of developing Alzheimer's disease and related dementias. The scientific premises of the proposed study are: 1) a combined sleep promotion and cognitive training intervention will have synergistic effects to mitigate the risk of cognitive impairment and development of Alzheimer's disease and related dementias in older ICU survivors; and 2) chronotherapeutic timing of interventions (i.e., adjusting timing of interventions according to circadian rhythm) may improve intervention efficacy.
The goal of this study is to learn if a new online training program is helpful to dementia family caregivers. This online program is fully computerized and supports 24/7 access from any location. The main questions it aims to answer are: - Does the training program improves the participants' well-being and sense of positive meaning? - If the program is found to be helpful, does it work through enhancing caregivers' self-belief or getting them to practice positive interpretation of caregiving challenges? To answer these questions, researchers will compare the online program to a waitlist control. Participants will: - Use the intervention (requiring internet access) in a self-guided manner - Respond to brief questionnaires at the beginning, and 1, 2 and 3 months afterwards
The purpose of this study is to test the Green Activity Program that was designed with Hispanic/Latino people living with memory challenges and their study partners to see if it can be done and if they enjoy the program. "Green activities" are nature activities that the person enjoys and can be done with other people or pets. For example, dog walking, hiking, outdoor yoga, and gardening are all green activities. The purpose of the program is to help people living with memory challenges participate in nature activities they enjoy. The goal of the program is to help people stay active and improve their health and well-being.
