The Patient Registry for Participation in Aging/Alzheimer's Research (PREPARE) is a database of individuals with Mild Cognitive Impairment who are interested in participating in research on aging/Alzheimer's disease and related dementias conducted at the Medical University of South Carolina (MUSC). PREPARE will connect MUSC researchers with potential participants so they can provide information about studies for which they may be eligible. PREPARE will also collect survey data from people with Mild Cognitive Impairment and their study partners to better understand the impact of this condition on daily functioning.

This is a Phase II research study to determine dosing of non-invasive brain stimulation for patients with Mild Cognitive Impairment (MCI) and depression. The brain stimulation treatment used in this study is called repetitive transcranial magnetic stimulation (rTMS). rTMS is a Food and Drug Administration (FDA)-approved treatment for depression. The goal of the study is to see if brain stimulation can be used for MCI patients to improve memory, thinking, and mood, and what dose of stimulation works best.

The study uses a form of rTMS called intermittent theta burst rTMS (accelerated iTBS). This treatment has not been FDA-approved for MCI patients. This double-blind study requires 11 study visits over the course of six months.

The purpose of the Alzheimer's Disease Registry Study (ADRS) is to (1) create a registry that will continue to provide study-ready subjects who meet research diagnostic criteria for the different stages of AD and who have been evaluated using research instruments that allow for their participation in clinical trial research, (2) provide a platform to allow for continual follow-up with registry participants to allow for their participation in clinical trial research at different stages of the disease process, and (3) to incorporate a population of veterans and minorities suffering from AD, a population that is not proportionally represented in clinical trial research, into the registry.

By collecting data pertaining to medical history, current medication details, family history, vital signs, and memory/thinking symptom concerns and evaluating a subject's ability to perform certain tasks, such as memory and thinking tests, questions about their daily activities, and social functioning; researchers are able to determine a research subject's potential eligibility in a clinical trial research protocol.

A registry with such information would enable researchers to effectively and efficiently identify potentially eligible research subjects for the program's evolving portfolio of Alzheimer's disease-related clinical trials.

Alzheimer's disease and Epilepsy may affect over 80% of individuals that have Down syndrome by the age of 60. Biomarkers found in the blood can enhance our understanding of the earliest changes linked to disease and may enhance clinical detection and healthy aging for individuals with Down syndrome.

The purpose of this study is to discover early neurobiological processes underlying the transition from healthy aging to disease. Our research team has developed technology that allows detection of small changes in the brain that get transferred to the blood.

We are recruiting individuals that either have or do not have Down syndrome for this biomarker study. Participants should be between the ages of 6 months and 85 years old and may include mothers and siblings of a child with Down syndrome. Infants and children will require consent form a parental or legal guardian.

Each participant will provide a blood sample for research purposes. We will also gather some basic health information about senses, habits, exercise level and smoking/vaping exposures.

Patients with Alzheimer Disease and patients with Heart failure (and a control group free from both the previous mentioned conditions) will be evaluated with cardiac and neuropsychological assessments, in order to investigate the relationship between the two conditions. The study consists of two initial visits, and a 4- and 8-year follow-up visit.

The purpose of this study is to use neuroimaging to understand how networks in the brain change over time. Although the single most significant risk factor for developing Alzheimer's disease (AD) is age, the neurobiological processes underlying the transition from normal aging to AD are not well understood. Our group of researchers has developed ways to use MRI to detect small changes in certain parts of the brain. We will use neuroimaging to understand how the connections in the brain change over time in healthy aging. The goal is to discover which brain changes are present in healthy aging.

Participants will have two study visits (about 2 years apart) where they will undergo tests to assess mental function, fill out questionnaires, and undergo a blood draw, brain MRI and PET scan and provide a saliva sample. At the second visit, participants will not repeat PET scan. Participants will continue to be followed longitudinally every two years as long as the study is funded.

Participants are required to have a Co-Participant accompany them for the first portion of each visit. This individual must be a reliable informant that has contact with the participant at least once per week.

With this research study, we want to learn if methylphenidate (Ritalin® and others) helps people with Alzheimer's disease and apathy (lack of interest or concern for things that others find moving or exciting).
