Filter by:The goal of this clinical trial is to learn whether a new smell test works as well as the standard clinical smell test, if there is a link between sense of smell and variations in the retina, and if these results could be used as a way to identify early stages of Alzheimer's disease. The main questions it aims to answer are: - Whether the test is as effective and reliable as the standard test - Whether there is a link between the results of the smell test and the structure of the back of the eye Participants will: - complete a short questionnaire - have pictures of the inside of their eyes taken - perform two smell tests
The purpose of this study is to assess the effectiveness, safety, and tolerability of BMS-986446 an Anti-MTBR Tau Monoclonal Antibody in participants with Early Alzheimer's Disease.
The New York Stem Cell Foundation (NYSCF) Research Institute is performing this research to accelerate diverse disease research using cells from the body (such as skin or blood cells) to make stem cells and other types of cells, conduct research on the samples, perform genetic testing, and store the samples for future use. Through this research, researchers hope to identify future treatments or even cures for the major diseases of our time.
Patients with Mild Cognitive Impairment (MCI) or Subjective Cognitive Decline (SCD) may or may not develop Alzheimer's disease (AD) dementia. Yet identifying patients at risk is crucial: delaying the onset of the disease by 5 years could reduce prevalence by 50%. To achieve this, we need affordable biomarkers combined with clinically meaningful assessment tools. Current approaches (cognition, imaging or Tau and Amyloid peptide assays) lack precision or specificity (e.g., age-related memory deficits) and involve invasive and costly procedures, sometimes inaccessible in France (e.g., the "AT(N)" framework). Recently, quantitative diffusion MRI (dMRI) has identified in-vivo gray matter microstructural changes linked to hyperphosphorylated Tau protein, which are of great diagnostic value. Still, we ignore whether and how these changes are responsible for early memory impairment in AD. The MIMA-P project will combine multi-compartment models of the high-resolution diffusion signal with a cognitive assessment of memory based on recent models of medial temporal lobe function to assess the relevance of a new affordable, rapid and non-invasive early marker of the disease.
The aim of the NODAL clinical trial is to demonstrate the feasibility of new, low-cost, non-invasive biomarkers of neurodegenerative pathologies as early Alzheimer and Parkinson, based on the estimation of the multimodal connectome.
The literature suggests a strong association between amyloid accumulation and gamma alterations, emerging gamma activity as a biomarker candidate for Alzheimer's pathology. The present study aims to investigate resting-state gamma activity changes in Cerebrospinal fluid (CSF)-proven early-onset Alzheimer's disease (EOAD) patients with a holistic approach that employs structural and functional brain neuroimaging techniques, and neuropsychological aspects.
This study is a multicenter, randomized, double-blinded, placebo-controlled Phase 3 study comparing LIPUS-Brain transcranial low-intensity pulsed-wave ultrasound device to placebo in patients with Early Alzheimer's Disease. The primary objective of the study is to assess changes in ADAS-J-cog-14 scores from baseline to 72 weeks.
This project will investigate the potential of Deep Brain Stimulation to improve cognitive abilities and counteract the effects of Alzheimer's disease. Deep Brain Stimulation electrodes targeting the Nucleus Basalis of Meynert (NB) will be implanted bilaterally in a cohort of patients. NB is the sole source of acetylcholine to the neocortex. Such stimulation may not only treat the cognitive symptoms but may have disease-modifying effects. Drawing from animal experiments in non-human primates that showed success of this approach, intermittent stimulation will be delivered at 60 pulses per second for 20 seconds of each minute for one hour per day. The study team will recruit patients, shortly after first being diagnosed with Alzheimer's disease. The study design will test the safety and efficacy of stimulation, potential benefits in cognitive function assessed with a battery of neurocognitive tests, cholinergic neurotransmission evaluated with Positron Emission Tomography, and ability to reverse Alzheimer's biomarkers, including beta amyloid and tau in the cerebrospinal fluid. Successful completion of this project will lead to a potential new intervention for the cognitive impairments of Alzheimer's disease.
Cognitive frailty, characterized by the coexistence of physical frailty and cognitive impairment, is a robust indicator of cognitive decline. Recognizing its significance, the International Association of Gerontology and Geriatrics and the International Academy on Nutrition and Aging have advocated for the use of cognitive frailty assessment as a means of monitoring the progression of mild cognitive impairment towards debilitating conditions like dementia, Alzheimer's disease, and loss of independence. Despite the clear need, a practical and remotely accessible tool for measuring cognitive frailty is currently lacking, especially within the context of telehealth visits. With telehealth video-conferencing becoming increasingly popular, accepted by healthcare payers, and preferred by older adults who may face difficulties traveling to a clinic, there is a pressing need for a software-based solution for remote cognitive frailty assessment that can be easily integrated into existing telehealth systems. This study proposes designing and validating a video-based solution to remotely monitor cognitive-frailty in older adults.
Alzheimer's disease (AD) is characterized by significant memory loss, toxic protein deposits amyloid and tau) in the brain, and changes in the gamma frequency band on EEG. The investigator's lab found that boosting gamma waves in AD mouse models using light and sound stimulation at 40Hz not only reduced amyloid and tau in the brain, but also improved memory. The investigators developed a light and sound device for humans that stimulates the brain at 40Hz that can be used safely at home. For the present study, 60 participants with mild Alzheimer's disease will be enrolled and will use this light and sound device at-home daily for 6-months. Investigators will measure changes in brain waves with EEG, blood biomarkers, the microbiome via fecal samples, functional and structural MRI scans, memory and cognitive testing, and questionnaires at 3 in-person visits throughout the study. After the 6-month time point, participants will have the option of continuing in the study for one additional year and completing an 18-month study visit. This study will provide critical insight into extended therapy involving non-invasive 40Hz sensory stimulation as a possible therapeutic strategy for mild to moderate Alzheimer's disease.
