Filter by:This study focuses on assessing and measuring white matter hyperintensities in individuals with amnestic mild cognitive impairment (aMCI) or Alzheimer's disease. Objective: The primary objective of the study is to quantify the extent and distribution of white matter hyperintensities in the brains of individuals diagnosed with amnestic mild cognitive impairment or Alzheimer's disease. White matter hyperintensities are areas of increased signal intensity observed on brain magnetic resonance imaging (MRI) scans, often associated with various cognitive disorders. Importance: Understanding the presence and severity of white matter hyperintensities in individuals with aMCI or Alzheimer's disease is crucial for several reasons. These abnormalities may serve as potential biomarkers, aiding in the early diagnosis and prognosis of cognitive disorders. Additionally, quantifying white matter hyperintensities could contribute to a better comprehension of the underlying neuropathological processes associated with these conditions. Methods: The study employs advanced imaging techniques, likely including MRI, to capture and analyze white matter hyperintensities in the brains of participants with amnestic mild cognitive impairment or Alzheimer's disease. The quantification process involves precise measurement and mapping of these hyperintense regions. Participants: The study involves individuals diagnosed with amnestic mild cognitive impairment or Alzheimer's disease. Participants will undergo neurological assessments and imaging procedures to facilitate the accurate measurement of white matter hyperintensities. Expected outcomes: Researchers anticipate that the quantification of white matter hyperintensities will provide valuable insights into the progression of cognitive disorders. The results may contribute to the development of more targeted and effective diagnostic and therapeutic interventions for individuals with amnestic mild cognitive impairment or Alzheimer's disease. Conclusion: This study represents a significant step toward enhancing our understanding of the neuropathological changes associated with amnestic mild cognitive impairment and Alzheimer's disease. By focusing on the quantification of white matter hyperintensities, researchers aim to uncover potential markers for early detection and monitoring of these cognitive disorders.
The goal of this clinical trial is to test a virtual reality (VR)-based program designed for cognitive stimulation in individuals attending the conventional cognitive rehabilitation program at the Day Hospital of CSSC (Centro Sociosanitario El Carme) in Badalona, Spain. The trial will specifically assess VR's impact on declarative memory and executive functions through interactive exercises, as well as attention and episodic memory through VR video stimuli. The main questions it aims to answer are: - Will patients with mild cognitive impairment find the VR program enjoyable and easy to use? - Can VR interventions help improve patients' cognitive functions, specifically attention and memory? - Do healthcare professionals find VR a practical tool for cognitive stimulation in their clinical practice? Participants will undergo a series of 8 sessions, scheduled twice a week to coincide with the conventional rehabilitation appointments. The VR equipment used will be Oculus Quest 2 headsets, offering an immersive experience with hand-tracking technology that simplifies interactions, particularly beneficial for those with mild cognitive impairment (MCI). During the study, participants will: - Engage with a VR-based cognitive stimulation program. - Undergo assessments of the participants´ cognitive functions before and after the intervention. - Provide feedback on the participants´ experience with the VR program. Researchers will analyze the data to see if: - The VR program leads to noticeable improvements in the cognitive abilities of participants. - The program is well-received and deemed beneficial by both patients and healthcare professionals.
Obstructive sleep apnea (OSA) is recurrent episodes of partial or complete obstruction of the upper airway during sleep that causes intermittent hypoxia and sleep fragmentation and potentially lead to cardiometabolic and neurocognitive sequelae. Chronic intermittent hypoxia, sleep fragmentation of OSA, and insufficient sleep have been significantly associated with higher risks of neurocognitive impairment, including mild cognitive impairment (MCI) and Alzheimer's disease. Thus, sleep and sleep apnea might be modifiable factors to neurocognitive impairment. Positive airway pressure (PAP) is the first line of treatment to maintain open airways for patients with OSA. Improving sleep, sleep apnea and circadian function could be a high-value intervention target to alleviate cognitive impairment and decline in subjects with mild neurocognitive impairment. Amyloid accumulation in brain tissue is a distinct feature of Alzheimers' disease, which is associated with potential impairment of neurocognition clinically. It predicts memory decline in initially cognitively unimpaired individuals. The study explores the associations between sleep apnea, cognitive function and cerebral imaging and the role of PAP therapy on neurocognitive trajectory in these patients with subjective cognitive impairment /mild cognitive impairment (SCI/MCI).
This pilot study investigates effects of a digital behavioral activation therapy in treating patients with mild cognitive impairment and mild dementia, applying a randomized controlled parallel group design. The primary goal is to estimate effect sizes for a larger trial. A further aim is to investigate the feasibility of study procedures and to validate new questionnaire scores. Primary outcomes are the change in the patients' quality of life and in their overall activity level.
To investigate factors that predict cognitive enhancement following engagement in an intensive Computerized Cognitive Training Protocol.
The Interventions for Brain Health Virtual Reality Study is a NIH-funded clinical research trial at the University of California San Diego (UCSD) Health under the supervision of the study principal investigator Dr. Judy Pa. The overarching goal of this trial is to use a novel virtual reality (VR) based intervention that simultaneously engages physical and cognitive activity aimed at improving brain health and cognition in older adults. The investigators will compare 3 types of interventions: physical activity, VR cognitive activity, and combined VR physical and cognitive activity over 16 weeks to evaluate physical and brain health changes.
The diagnosis of diseases causing memory difficulties or dementia is often challenging. Without the use of advanced methods such as cerebrospinal fluid tests, approximately 25-30% do not receive a correct diagnosis today. However, the investigators have recently developed new blood biomarkers with high diagnostic accuracy, and the investigators now want to investigate whether they can eventually replace cerebrospinal fluid tests. This is because blood tests are much more cost-effective and significantly easier for patients compared to cerebrospinal fluid tests. In this study, 1200 patients undergoing clinical evaluations at the Memory Clinic, Skåne University Hospital in Malmö, are included for blood and cerebrospinal fluid sample collection. The blood samples are sent for analysis using the new blood biomarkers. Subsequently, the results are compared with those from the clinical analysis of cerebrospinal fluid to determine how well they perform in routine clinical practice as an alternative to cerebrospinal fluid tests and whether the blood test improves patient care. This comparison is carried out by the attending physician in three steps: 1. Assessment without access to the results of either the blood test or cerebrospinal fluid test. 2. Assessment with access to only the results of the blood test. 3. Assessment with access to the results of both the blood test and cerebrospinal fluid test. Aim 1) To prospectively validate plasma Alzheimer's disease (AD) biomarkers for diagnosis of patients with cognitive symptoms who are evaluated in a specialist memory clinic. Aim 2) Determine whether blood AD biomarkers improve patient management in specialist memory clinic settings.
Objective 1: To scale-up the nutrition adherence intervention for testing in predominantly Black and African-American rural communities in North Florida. The investigators hypothesize that: 1. The protocol will produce at least 75% of participants obtaining measurable levels of urine ketones (e.g., good adherence) in the Mediterranean-Ketogenic nutrition (MKN) group and an average score of >9 on the MEDAS questionnaire in the Mediterranean group during the 10-week program. Objective 2: To evaluate the effects of adherence to Mediterranean versus Mediterranean-Ketogenic nutrition on novel gut-brain axis markers of Alzheimer's disease pathogenesis in individuals with mild cognitive impairment compared to cognitively normal older adults. The investigators hypothesize that individuals with mild cognitive impairment will: 1. Have greater evidence of gut dysbiosis at baseline than cognitively normal controls and 2. Will demonstrate greater increases in beneficial gut microbial metabolites in response to adherence to Mediterranean-Ketogenic nutrition and the Mediterranean diet compared to CN controls.
This research study aims to examine biomarkers of Alzheimer's disease (AD) as early as possible which could potentially be a screening tool for the general population. This observational study will take place at the Skåne University Hospital in Sweden. The study will enroll up to 600 cognitively healthy subjects aged 50 to 80 years with 3/4 having preclinical Alzheimer's disease. Recruitment and enrollment will be ongoing for 2-3 years, and subject participation will be lasting approximately 4 years. Disclosure of AD risk assessments will be an optional procedure.
The overall aim of the study is to improve the diagnostic accuracy of AD and cognitive impairment in primary care settings to ensure better care and treatment as well as facilitate correct referrals to specialized memory clinics. The investigators will strive to recruit diverse and representative populations of patients with subjective cognitive decline (SCD), mild cognitive impairment (MCI) and mild dementia. The specific aims of the study are to: 1. Improve the detection of mild cognitive impairment (MCI) and dementia in primary care. 2. Develop and evaluate cognitive tests, blood-based biomarkers and brain imaging methods that are suitable for accurate and early diagnosis of Alzheimer's disease (AD) in primary care. 3. To prospectively validate plasma AD biomarkers for diagnosis of patients with cognitive symptoms who are evaluated in primary care. 4. Determine whether blood AD biomarkers improve patient management in primary care.
