Filter by:A 6-month pilot randomized controlled trial designed to test the effect of the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) Diet + usual medical care versus usual medical care on cognitive change and several other secondary outcomes through a randomized controlled trial in 60 mild stroke patients aged 35-70 years without dementia.
Cerebral amyloid angiopathy (CAA), a common cerebrovascular small vessel disease (SVD), is a frequently (98%) found co-morbidity at autopsy in patients with Alzheimer's disease (AD). Current in vivo hallmarks of CAA represent changes relatively late in the disease process and leaves CAA in AD often undetected. Recently, it was shown that decreased vascular reactivity (VR) measured with blood oxygen level dependent (BOLD) MRI, after visual stimulus, is an early CAA marker. With BOLD-MRI to detect decreased VR in different stages of AD, it was shown that increasing stages of AD associate with decreasing VR independent of age, classic SVD markers and atrophy. Moreover, VR is associated with cognitive deficits. Therefore, cross-sectional data indicate that decreased VR is an important co-morbidity already in early stages of AD with an independent effect on disease severity. In this respect, the study aim is to determine the natural course of the decrease of VR in both controls and (early stage) AD patients to monitor AD disease progression. This is an essential step to aid in the development and application of effective treatment as it is expected that CAA can cause/worsen AD pathology.
The goal of this observational study is to investigate the frequency and the possible pathogenic role of neuronal synaptic antibodies (NSAb) in patients with cognitive impairment (CI). The main questions it aims to answer are: 1. the frequency and associated features of NSAb in patients with CI and the usefulness of a clinical score in improving autoimmune dementia (AID) diagnosis; 2. the clinical significance of NSAb in patients with CI not fulfilling the autoimmune encephalitis (AE) criteria and serum NSAb (NSAb-pos-CI); 3. the impact of blood-brain-barrier (BBB) dysfunction on their pathogenicity.
Building upon prior work, the investigator team developed a communication intervention for older adults with ADRD who are considering a decision about cancer management (adapted intervention: COACH-Cog). The investigators hypothesize that for patients with dual diagnoses of ADRD and cancer, COACH-Cog will increase autonomy support of care partners and patients in the decision-making process, leading to greater acknowledgement and support of cognitive concerns and cognitive-related goals, thereby improving goal concordant care. The investigators are conducting a pilot randomized controlled trial (RCT; cluster randomized by physician) including approximately 45 oncology clinicians and 130 patient/care partner dyads evaluating the effect of COACH-Cog on care partner and patient autonomy support, care partner well-being, goal-concordance, and communication.
HAAL project aims to test several technological devices in order to improve the quality of life of older people with dementia and their informal and formal caregiver.
The goal of this observational study is to investigate the correlation between self-compassion, depression, and quality of life among primary caregivers of persons with dementia. The main questions it aims to answer are: 1. What is the current status of self-compassion, depression, and quality of life among primary caregivers of persons with dementia? 2. Are there differences in self-compassion, depression, and quality of life among primary caregivers of persons with dementia based on different background variables? 3. What is the correlation between self-compassion, depression, and quality of life among primary caregivers of persons with dementia? Participants will fill out the questionnaire to complete the study.
Prospective interventional study with a device for comparing autonomic parameters among patients with different forms of cognitive decline
The purpose of this study is to assess the efficacy and safety of DMB-I for the treatment of patients with Alzheimer type dementia.
This is a randomised controlled study aiming to evaluate the implementation of a website ('Small Steps') to support the modification of participants' time-use behaviour to reduce the risk factors for dementia. 'Small Steps' website provides the tools for this with a visual representation of the participant's current use of time and allowing manipulation to demonstrate how small lifestyle changes may improve and meet sleep and physical activity needs. Participants will be assisted to make changes to current behaviours with the aim to reduce the time they spend sitting (sedentary behaviour), increase physical activity, and improve sleep duration and quality. Participants (aged 65 or older) will be randomly allocated to one of two groups, the 'Extended Program' (intervention) group or the 'Condensed Program' (control) group. There are 3 phases (Introductory, Maintenance and Follow-Up; each 12-weeks long) to this program and in total the program is 36-weeks long. Participants will use a tailored website to help support them in making progressive changes over the first 12 weeks. They will then try to maintain these behaviour changes for as long as possible. There will be in-person health testing during each phase and information about sleep habits, sleep quality, and motivation will be assessed using online surveys. Physical activity levels and sleep duration will also be assessed.
Biomarkers for Vascular Contributions to Cognitive Impairment and Dementia (MarkVCID) is an NIH-funded consortium dedicated to finding biomarkers involved in age-related thinking and memory problems. Alzheimer's disease and other dementias leave signatures on brain scans or in the blood called biomarkers. The MarkVCID study will measure a panel of candidate biomarkers in 1800 participants and watch them closely to see what they tell us about changes in brain function and risk of memory loss. Age-related problems in thinking and memory represent some of the greatest risks to public health in the US and globally. Diseases that affect small blood vessels in the brain have been shown to be major contributors to these changes. However, research and patient care can be held back by limited biomarkers that identify who should be treated. The MarkVCID Consortium includes 17 US medical centers, a Coordinating Center, an External Advisory Committee, and NIH leadership. Data and biospecimens collected as part of this research study will be stored in a research database and biorepositories, so that researchers can use this information to study brain function.
