A Study to Evaluate Safety and Tolerability of Aducanumab in Participants With Alzheimer's Disease Who Had Previously Participated in the Aducanumab Studies 221AD103, 221AD301, 221AD302 and 221AD205

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).

AHEAD 3-45 Study: A Study to Evaluate Efficacy and Safety of Treatment With Lecanemab in Participants With Preclinical Alzheimer's Disease and Elevated Amyloid and Also in Participants With Early Preclinical Alzheimer's Disease and Intermediate Amyloid

The primary purpose of this study is to determine whether treatment with lecanemab is superior to placebo on change from baseline of the Preclinical Alzheimer Cognitive Composite 5 (PACC5) at 216 weeks of treatment (A45 Trial) and to determine whether treatment with lecanemab is superior to placebo in reducing brain amyloid accumulation as measured by amyloid positron emission tomography (PET) at 216 weeks of treatment (A3 Trial).

Hypertension, Intracranial Pulsatility and Brain Amyloid-beta Accumulation in Older Adults (HIPAC Trial) (HIPAC)

The aim of this study is to determine if lowering blood pressure using FDA approved medication (antihypertensive drugs) alters brain pulsatility and reduces brain amyloid beta protein accumulation in older adults. Amyloid beta protein is high in the brain of older adults with Alzheimer's disease. Hypertension may increase brain amyloid beta protein accumulation and affect memory and thinking ability in older adults. However, whether lowering blood pressure reduces brain amyloid beta protein and improves brain function is inconclusive. The investigators hypothesize that treating high blood pressure alters brain pulsatility, which in turn reduces brain amyloid beta protein accumulation and improves brain structure and function.

PST for Care Partners of Adults With Alzheimer's and Alzheimer'S-related Dementia

Caregivers of individuals with Alzheimer's disease and related dementia rarely get the preparation or training they need to manage their caregiving responsibilities and to successfully balance their own self-care and their caregiving roles. As a result, caregivers often experience caregiver burden, emotional distress, and substance abuse. Therefore, there is a critical need to support the emotional and social functioning of caregivers to improve their health and well-being and to prevent caregiver burden and poor coping. Problem solving training (PST) is an evidence-based approach that teaches and empowers individuals to solve emergent problems contributing to their depressive symptoms, helps improve coping skills and increases self-efficacy. However, critical gaps in knowledge and care remain regarding the necessary components of training (eg. How many sessions? What is the influence of personal factors?) that affect how effective PST is for individual caregivers. Finally, caregiver interventions have almost exclusively been tested in English-speaking caregivers, further contributing to existing health disparities among minority groups. To address this critical need, Dr. Shannon Juengst, Assistant Professor of Physical Medicine and Rehabilitation was awarded a new Texas Alzheimer's Research and Care Consortium Collaborative Research Grant entitled, "Problem Solving Training (PST) for English- and Spanish-speaking Care Partners of Adults with Alzheimer's and Alzheimer's Related Dementia." For this project, Dr. Juengst has assembled a strong, multidisciplinary team with Dr. Gladys Maestre, Professor of Biomedical Sciences and Director of the NIA funded-Alzheimer's Disease Resource Center for Minority and Aging Research and Memory Disorders Center at UT Rio Grande Valley and Dr. Matthew Smith, Associate Professor of Environmental and Occupational Health and Co-Director of the Center for Population Health and Aging at Texas A&M University. This project will establish the necessary guidelines for an evidence-based, implementable problem-solving intervention for both English- and Spanish-speaking caregivers to improve their health and well-being and identify potential mechanisms of action for such training.

Alzheimer's Disease Neuroimaging Initiative 3 (ADNI3) Protocol (ADNI3)

Since its launch in 2004, the overarching aim of the Alzheimer's Disease Neuroimaging Initiative (ADNI) has been realized in informing the design of therapeutic trials in AD. ADNI3 continues the previously funded ADNI-1, ADNI-GO, and ADNI-2 studies that have been combined public/private collaborations between academia and industry to determine the relationships between the clinical, cognitive, imaging, genetic and biochemical biomarker characteristics of the entire spectrum of Alzheimer's disease (AD). The overall goal of the study is to continue to discover, optimize, standardize, and validate clinical trial measures and biomarkers used in AD research.
