A Double-blind Dual Study Assessing Safety and Efficacy of Buntanetap in Participants With Early AD

Early Alzheimers Disease

The goal of this clinical trial is to learn if buntanetap/Posiphen works to treat early Alzheimer's disease in adults aged 55-85. It will also learn about the safety of buntanetap/Posiphen. The main questions it aims to answer are: * Does buntanetap/Posiphen improve cognition as measured by ADAS-Cog13? * Does buntanetap/Posiphen improve function as measured by ADCS-iADL? * What medical issues do participants have, if any, when taking buntanetap/Posiphen? Researchers will compare buntanetap/Posiphen to a placebo (a look-alike substance that contains no drug) to see if buntanetap/Posiphen works to treat early Alzheimer's disease. Participants will: * Take buntanetap/Posiphen or a placebo every day for 18 months * Visit the clinic periodically for checkups, tests, and questionnaires (screening visits, enrollment, month 1, month 3, month 6, month 9, month 12, month 15, month 18), including a volumetric MRI at month 6 and month 18 * Complete pre- and post-clinic visit phone calls

Retinal Hyperspectral Imaging in Neurodegenerative Diseases

Dementia Neurodegenerative Diseases Alzheimer Disease Parkinson Disease +4

Hyperspectral retinal imaging is a non-invasive imaging modality in which a series of images of the retina are captured using light of different wavelengths. The resulting "hypercube" of data provides a wealth of information about the retinal structure. Our group has developed evidence supporting a role for this technology in the detection of retinal amyloid beta in Alzheimer's disease. We are undertaking further studies to establish the role of this method in the assessment of people with dementia, or those at risk of Alzheimer's disease. In addition, we wish to test whether the approach may have value in other forms of dementia or neurodegenerative disease such as Parkinson's disease, Lewy-Body dementia or vascular dementia.

TAS Test: Online Motor-cognitive Tests for Early Detection of Alzheimer's Disease

Alzheimer Disease Dementia Age-related Cognitive Decline

Global dementia prevalence is rising. Alzheimer's disease (AD), the most common cause, has devastating effects on people's quality of life. AD has a preclinical (pre-AD) period of 10-20 years when brain pathology silently progresses before any cognitive symptoms appear. Current tests for pre-AD are invasive, costly and unsuitable for screening at population level. Similar to screening for pre-diabetes and carcinoma in situ, it is important to detect AD at the preclinical stage in order to offer early interventions before the pathology progresses to the irrerversible degenerative stage. In the study, research will develop a new scalable test (TAS Test) by combining two innovative ideas: hand-movement tests to detect pre-AD \>10 years before cognitive symptoms begin; and computer vision so people can "self-test" online using home computers. This unique approach builds on recent discoveries that hand-movement patterns change in pre-AD. The research team will use exquisitely precise computer vision methods to automatically analyse movement data from thousands of participants, and combine this with machine learning of overall motor-cognitive performance. The project team has access to 3 well-phenotyped cohorts, \>10,000 existing participants and a cutting-edge assay for a blood AD biomarker, ptau181. The research team will develop a TAS Test algorithm to classify hand-movement and cognitive test data for pre-AD risk (p-taua181 levels) and determine TAS Test's precision to prospectively predict 5-year risks of cognitive decline and AD.

Remotely-supervised Neuromodulation in PPA

Primary Progressive Aphasia(PPA) Progressive Aphasia Progressive Aphasia in Alzheimer's Disease Logopenic Progressive Aphasia (LPA) +2

The goal of this clinical trial is to learn whether home-based brain stimulation combined with virtual speech-language therapy can improve communication abilities in adults with logopenic variant primary progressive aphasia (lvPPA), a language disorder most often caused by Alzheimer's disease. The main questions the study aims to answer are: * Is combining remotely supervised transcranial direct current stimulation (tDCS) with virtual speech-language therapy feasible and acceptable for people with lvPPA? * Does this combined treatment lead to improvements in communication compared to speech-language therapy with sham (placebo) stimulation? * Do individual brain characteristics help predict who benefits most from this treatment? Researchers will compare participants who receive active tDCS plus virtual speech-language therapy to participants who receive sham (placebo) tDCS plus virtual speech-language therapy to see if active brain stimulation enhances communication outcomes. Participants will: * Complete speech-language therapy sessions delivered by video visit. * Receive either active or sham tDCS that is remotely supervised and completed at home. * Complete language and cognitive testing before and after treatment. * Undergo brain imaging and other assessments to help understand treatment response.

FACE Phase II (a Stage II Trial)

MCI Subjective Cognitive Decline (SCD) Mild Behavioral Impairment

How to ensure adherence to computerized cognitive training in unsupervised circumstances (e.g., at-home, self-administered) in older adults at risk for Alzheimer's disease (AD) or AD related dementia (AD/ADRD) is understudied. The objective of the R33 study is to test a novel facial expression-based personalization engine (FPE) for monitoring and modulating real-time effective engagement, with an ultimate goal of enhancing long-term adherence in unsupervised cognitive training in older adults at risk for AD/ADRD. Here, Effective engagement is defined as the extent to which someone is actively engaged and performing with significant attention and enjoyment while training, addressing a balance between adherence and cognitive gains/plasticity from the training. Based on previous work, the hypotheses include that (1) mental fatigue revealed in facial expressions will reflect a trainee's degree of effective engagement, which can be modified by modulating task novelty; (2) the proposed FPE will ensure the effective engagement in cognitive training by monitoring trainee facial expressions and modulating training in response, promoting the trainee's long-term adherence to the training and cognitive plasticity. A Stage II intervention efficacy study will be conducted to compare effective engagement and adherence in unsupervised cognitive training between training programs with vs. without FPE in older adults at risk for AD/ADRD. The proposed FPE may assist in monitoring and improving effective engagement and adherence in older adults with unsupervised cognitive training. In the current application, FPE in a cognitive training program called speed of processing training will be tested. However, such FPE may be embedded to any computerized cognitive training in future studies to help address adherence related issues.

Mediators and Moderators of Auditory Training

Hearing Handicap

The goal of this clinical trial is to learn how Auditory Training (AT) may help people better understand speech in noisy environments. As people get older, it becomes harder for them to hear speech clearly when there is background noise. This can be frustrating, and it can affect their independence and quality of life. AT is often used to support people with and without hearing loss, especially when a person is not a good candidate for a hearing aid or when amplification from a hearing aid does not improve performance. The investigators want to gather reliable data to understand how AT works and what affects its success. The main questions the trial aims to answer are: * How do different types of sounds influence the effectiveness of auditory training? * Which auditory training approaches are most successful in improving speech understanding? * How do personal traits impact the results of auditory training? The investigators will study a large and diverse group of 1,260 participants, including both young and older adults, to evaluate various auditory training approaches. You will: * Take part in auditory training sessions that include different types of auditory tasks. * Complete tests that measure how well they understand speech in both quiet and noisy settings. * Complete surveys on personal data like demographics, hearing challenges and other factors to help researchers understand what might influence training results. The investigators will measure and compare the results of these approaches to find out which ones are most effective. This could help people who are at risk of cognitive decline, like those at risk for Alzheimer's disease.

PET Imaging of Cyclooxygenases in Neurodegenerative Brain Disease

Parkinson's Disease Dementia Alzheimer's Disease ALS +1

Background: About 5 million adults in the U.S. have Alzheimer s disease or another adult-onset neurodegenerative disorder. Many studies have found that inflammation in the brain contributes to these diseases. Researchers want to find a better way to measure this inflammation. Objective: To learn whether COX-1 and/or COX-2 is elevated in the brains of individuals with neurodegenerative brain disease compared to healthy volunteers. Eligibility: Adults age 18 years and older in good general health who have an adult-onset neurodegenerative dementia, such as AD, FTD, corticobasal syndrome, Huntington s disease, or MCI, ALS and healthy adult volunteers enrolled in protocols 01-M-0254 or 17-M-0181. Design: Participants will be screened with medical history, physical exam with vital signs, and lab tests. They will have a neuropsychological testing. Their heart function will be measured. Participants will have a magnetic resonance imaging (MRI) scan. The MRI scanner is a metal tube surrounded by a strong magnetic field. Participants will lie on a table that slides in and out of the tube. The machine makes noise. Participants will get earplugs. Participants will have 2 PET scans. They will be injected with the study drugs through an intravenous catheter placed in an arm vein. The PET scanner is shaped like a doughnut. Participants will lie on a bed that slides in and out of the scanner. A plastic mask will be molded to their head to keep them from moving. A thin plastic tube will be put into an artery at the wrist or elbow crease area. This will be used to draw blood during the scan. Participants will have 2-5 study visits. Participation lasts 1 week to 4 months, depending on scheduling.
