Filter by:This is a single-blind, sham-controlled, clinical trial that aims to evaluate the safety, tolerability, and feasibility of delivering audiovisual stimulation via a Virtual Reality (VR) headset to people with mild Alzheimer's disease and age-matched healthy participants.
In the ADDITION-MCI project, patients with a diagnosis of mild cognitive impairment probably caused by Alzheimer's disease will receive plasma exchange.
The goal of this observational study is to validate changes in speech as a measure of cognition in individuals at increased risk of Alzheimer's disease and related dementias (ADRD). This study aims to clarify how speech may be affected by Alzheimer's disease. Participants will complete speech collection sessions and a survey at home using an iPad. Participants can expect to be in the study for 3 years.
The temporal sequence of microglial activation, changes in functional and structural connectivity and the progression of neurocognitive deficits has not been conclusively clarified. To date, there have been no studies of the topographical and pathogenetic relationship between microglial activation and network degeneration. The main aim of the present study is to investigate the relationships between functional, structural MRI connectivity and microglial activation at different stages of AD in a multimodal approach. Genetic predisposition and biomarkers in blood and cerebrospinal fluid will also be taken into account in order to close the explanatory gap in pathogenesis between the known molecular pathological changes and their effects at system level in an integrative approach.
Acrylamide, a widespread food-processing contaminant, poses a major public health concern due to its high exposure level in the general population and its toxicity. While animal evidence shows that acrylamide causes neurological alterations and may play a role in cardiovascular disease, evidence in humans is lacking. Our project aims to investigate whether dietary acrylamide exposure, measured in blood, increases the risk of dementia, Alzheimer's and Parkinson's diseases and myocardial infarction. In addition, the aim is to improve the understanding of the biological mechanisms underlying these associations integrating small compounds in blood (i.e., OMICS). In two population-based cohorts, the Cohort of 60-Year-Olds and the Swedish Mammography Cohort, acrylamide will be assessed in blood samples using a case-cohort design (around 2145 individuals, 20-year follow-up). The results will be presented in four scientific publications using adequate data analysis. The project will run from 2024-2028. The project´s findings will help improve public health through safer food and better nutrition. If findings indicate that acrylamide increases the risk of these diseases, this will urge interventions to decrease acrylamide exposure via food production and consumption. In turn, this will help to reduce the burden of these diseases. Even findings showing null association will be equally relevant to avoid unnecessary and costly preventive measures.
The specific aim of the pragmatic trial is to evaluate the practical utility and effect of the PDM, the QDRS, and the combined approach (PDM + QDRS) in improving the annual rate of new documented ADRD diagnosis in primary care practices.
The purpose of this study is to establish multiple points of clinical validity for the Altoida digital biomarker assessment in individuals with a clinical diagnosis of cognitively normal (CN) and Mild Cognitive Impairment (MCI). Participants will use the Altoida app and the de-identified sensor data captured by the device will be used to train specific machine-learning algorithms to recognize early symptoms of cognitive decline, such as MCI or MCI with likelihood of amyloid pathology, as measured by digital biomarkers (T1 - Visit 1). Participants will be invited for an additional visit to evaluate test-retest reliability (T1' - Visit 2). Optionally, an updated variation of the Altoida app will be tested over the course of two additional visits to ensure optimal digital assessment delivery based on best practices in neuropsychological testing, user experience design, and data collection integrity (T2 - Visit 3 and T2' - Visit 4).
The purpose of this study is to learn more about the safety, effectiveness and tolerability of the study drug called Benfotiamine which may delay or slow the progression of the symptoms of early Alzheimer's disease.
This study is designed to evaluate the impact on the quality of life and wellbeing of a person-centered online dance program on people living with dementia or MCI and care partners. The duration of the study will be 1 year. Each participant in the study will be followed for approximately 4 months. The study includes joining a weekly 1-hour dance program online on Zoom for 12 weeks. Prior and after the dance program, participants will meet with the research coordinator to answer some questionnaires about wellbeing and reflections on their experience in the program. After the completion of the dance program, participants will be invited to join a focus group to reflect of the impact of the program with fellow participants. The study will enroll up to 72 participants. This includes 36 dyads of persons living with dementia or MCI and their care partners. The study will enroll community-dwelling people living with a diagnosis of mild cognitive impairment or mild to moderate-stage dementia and care partners living in the United States.
This is a prospective multicenter study with Alzheimer's patients with dysphagia. Patients enrolled are randomly divided equally into the observation group and the control group. All patients receive conventional care, and the observation group received Intermittent Oral-esophageal Tube Feeding while the control group received Nasogastric Tube Feeding for enteral nutrition support. Baseline information (demographics, medical history, etc.), nutritional status at admission and after treatment, depression, dysphagia, and quality of life after treatment are compared.
