Filter by:The primary objective is to evaluate the safety and tolerability of aducanumab over 100 weeks of treatment after a wash-out period imposed by discontinuation of feeder studies in participants who had previously received aducanumab (i.e. previously treated participants) or who had previously received placebo (i.e. treatment-naïve participants).
The primary objective is to characterize trajectories of change on the primary outcome measures in this study population through longitudinal collection of measures of cognition, function, behavior, and health status.
The overall objective of this study is to compare the overall pattern of [18F]APN-1607 uptake in subjects with MDAD, subjects with AD dementia, and healthy subjects.
This study is an RCT to evaluate the effectiveness of Brain Safe on reducing anticholinergic exposure. Over 42 months, the trial will enroll 700 community-dwelling older adults who were prescribed one or more strong anticholinergics. Participants will be randomized to use the Brain Safe app or an attention control medication list app for 12 months, with monthly usage reminders.
The purpose of this study is to test a new technique that may, in the future, help deliver medications to the brain of people with Alzheimer's disease. Participants in this study will undergo a focused ultrasound treatment to the brain, along with Magnetic Resonance Imagine (MRI) and Positron Emission Tomography (PET) scans.
Dementia is a clinical syndrome that is the result of distinct underlying pathologies including Alzheimer's disease (AD). Despite more than two decades of research on prevention and treatment of dementia and aging-related cognitive decline, highly effective preventive and therapeutic strategies remain elusive. Many features of dementia render it especially challenging. Indeed development of disease occurs insidiously over the course of years or decade. In addition, the causes of dementia and determinants of its severity are likely multi-factorial. To overcome these challenges and better understand the causes and course of AD and related disorders, long term follow-up studies of persons at high risk of dementia are required including multidimensional and harmonized assessment of risk factors, phenotypes (cognition, neuropsychiatric symptoms, physical health, self rated health) and endophenotypes (blood markers, genetic markers, neuroimaging markers). This project proposes an extension of the follow-up of Memento participants over 5 to 10 years with of focus on cognitive outcomes and comorbidities.
The objective of this study is to compare the effectiveness of 2 intervention delivery strategies for increasing moderate physical activity (MPA), real-time group video conferencing (RGV) vs. enhanced usual care (EUC), in community dwelling adults with Alzheimer's diseases (AD) and their caregiver (dyads) over 18 mos. (6 mos. active, 6 mos. maintenance, 6 mos. no contact). The primary outcome is to compare total MPA (min/wk.), assessed using ActiGraph, in adults with AD from baseline to 6 mos. Secondary aims for the Adults with AD are to compare MPA (min/wk), sedentary time (min/wk.), percentage meeting 150 min/wk. goal, functional fitness, activities of daily living (basic/instrumental), quality of life, residential transitions, and cognitive function across 18 months between RGV and EUC. Secondary aims for the caregivers are to compare total MPA (min/wk.), sedentary time (min/wk.), functional fitness, quality of life, caregiver burden across 18 months between RGV and EUC. Additionally, as an exploratory aim, this study will evaluate the influence of process variables/participant characteristics on MPA in adults with AD and their caregiver across 6, 12 & 18 mos.: age, sex, BMI, attendance (exercise/support sessions), use of recorded videos, PA self-monitoring, peer interactions during group sessions, caregiver support, type and quality of dyadic relationship, and number of caregivers.
The goal of this study is to explore the efficacy and safety of 4Hz transcranial alternating current stimulation (tACS) in patients with mild Alzheimer's disease (AD). The study will recruit 40 individuals with mild AD, and the participants will be randomized to either a 4 Hz tACS group or a sham stimulation group. Both groups will undergo 30 one-hour sessions across 3 weeks (21 days). At the end of the intervention and 3-month follow-up, all subjects will repeat the baseline assessments.
In this trial, the safety and effect of daily exposure to light and sound stimulation on people with mild Alzheimer's Disease (AD) will be studied. COVID-19 Amendment: Due to the ongoing suspension of all in-person humans subject research across MIT in response to the COVID-19 pandemic, all enrolled participants who have not completed their 6-month visit will have their visit postponed to 9 months with a follow up at 18 months. Subjects who have completed their 6-month visit will still be instructed to continue and return at Month 12 for an evaluation. OPTIONAL: If the subject would like to come in for an evaluation between Month 9 and 18, we will invite participants to come on Month 12 to complete cognitive testing and EEG.
Alzheimer's disease (AD) is characterized by significant memory loss and toxic protein deposits (amyloid and tau) in the brain. The investigators' lab found a non-invasive way to remove these toxic proteins from the brain in AD mouse models. Remarkably, treated mice also have improved memory on behavioral testing. The investigators aim to translate this non-invasive method, which uses light and sound to stimulate the brain, to be used in mild Alzheimer's patients. 40 participants with mild Alzheimer's disease will be recruited, and the investigators will assess their brain waves with electroencephalogram (EEG) before, during, and after light and sound stimulation for safety, feasibility, and to optimize the stimulation device for use in the mild AD population.
