Mild Cognitive Impairment Clinical Trials

Efforts to find treatments for AD have yielded only modest benefits, likely because longstanding AD pathological processes induce irreversible neurological compromise. These processes begin years before the onset of clinical symptoms. This possibility has been incorporated into a model describing stages of AD development, articulated by the NIA/Alzheimer's Association preclinical workgroup of which the Co-Director of the Kulynych Alzheimer's Research Center, Dr. Suzanne Craft, was a member. According to this model, the best hope for countermanding the effects of AD lies in intervening at the earliest possible point in the pathological cascade. There are several important ongoing efforts in adults with preclinical AD that directly target amyloid aggregation. Although this strategy addresses an important aspect of the AD pathological cascade, we believe that addressing metabolic dysfunction affecting glucose and insulin regulation offers a complementary approach, in that it may reduce amyloid burden and toxicity, while also directly enhancing synaptic health, brain metabolism, tau regulation and neurovascular function. The purpose of the ADCC is to identify and characterize early risk factors that predict cognitive decline and dementia in asymptomatic adults and adults with early signs of cognitive impairment. The data obtained from this study, collected at enrollment and follow-up will allow us to examine disease trajectory in individuals with and without prediabetes and other measures of glucoregulatory dysfunction in this process. The enrollees, who will be well-characterized with regard to cognitive and metabolic status through ADCC assessments, will provide an important resource for other local (institution) and national investigations. Data collected from participants enrolled in the ADCC will be stored indefinitely for future investigations. Read Less

The Brain Energy for Amyloid Transformation in AD (Alzheimer's disease) or BEAT-AD study will compare the effects of a ketogenic low-carbohydrate diet and a low-fat diet in adults with mild cognitive impairment. The data collected will help determine whether diet interventions induce changes in cognitive function, cerebral blood flow, and levels of certain proteins and hormones in body fluids. The study will include volunteers who have mild cognitive impairment, who will be randomly assigned to receive either a ketogenic low-carbohydrate diet or a low-fat diet for 16-weeks, with follow-up assessment 8 weeks after diet completion. Study measures, clinic visits and phone sessions will occur at baseline and throughout the 24-week study. Participant will follow either a low-carbohydrate or low-fat diet that will be individually planned with help from a study dietitian. After completing the study diet for 16 weeks, participants will resume their normal diet. The final visits will occur at week 24 (8 weeks after the completing the diet). At the end of the 24-week study, participants will be given the opportunity to meet with the study dietitian for education and assistance with planning a healthy diet. Read Less

The objective of this study is to test the effects of caffeine on neurocognitive and clinical recovery after major surgery. Specifically, this trial tests the primary hypothesis that caffeine will reduce the incidence of postoperative delirium. Read Less

This a two phase project that aims to pilot a new adaptation (Phase 1) of Motivationally Enhanced Compensatory Cognitive Training for Mild Cognitive Impairment (ME-CCT; an originally VA-based cognitive rehabilitation manualized intervention for older adults with MCI, with a focus on the impact of stress on cognitive functioning; that integrates components from the Race Based Stress and Empowerment (RBSE) group for an increased focus on race-based stress and discrimination for racial minority older adults (i.e., RBSEF-CCT-MCI). In a pilot open trial, 75-150 participants will receive group-based intervention for 8 weeks, with 8-10 participants per group. Following the pilot study, the investigators will complete a randomized controlled trial (RCT) (Phase 2) to compare the efficacy of the RBSEF-CCT-MCI with the ME-CCT. In the RCT, 75-150 participants will be randomized into either 1) The active control group, who will complete the original, ME-CCT training program, or 2) The experimental group, who will complete the newly developed RBSE-CCT-MCI. Both research groups will complete the interventions for 8 weeks, with 8-10 participants per group. Hypothesis: Participation in this newly developed/updated intervention (i.e., RBSEF-CCT-MCI) will result in improvements in both (a) subjective and (b) objective cognitive functioning, and (c) self-reported mental health symptoms.

This study aims to test a new technology-based program designed to help improve the ability to manage chronic conditions. This program includes daily smart speaker use for managing different tasks and technology learning. Proper self-management of chronic conditions is critical to the maintenance of health. Digital technologies offer substantial potential to enhance self-management behaviors. Voice-operated smart speakers hold promise due to their ability to provide functional, cognitive, and social stimulation, send targeted reminders, and assist with daily schedules. Unfortunately, many older adults who live in low-income communities lack the resources and proficiency to take advantage of these options. Additionally, cognitive impairment is prevalent in independent living older adults, more prevalent in low-income older adults. The goal is to address these critical challenges by identifying smart speaker-based functions preferred by older adults, exploring their technology challenges, introducing them to these functions, and providing necessary technology training to improve self-efficacy in managing chronic conditions and enhance their engagement in self-management behaviors.

CORT-X will examine if mitigation of stress-mediated pathogenesis of Alzheimer's disease (AD) is a feasible target for intervention in individuals at risk for this disease. This single-site (Baltimore, Maryland) phase II clinical trial is a 2-week, randomized, placebo-controlled crossover study of the effects of the selective glucocorticoid receptor antagonist, CORT108297, on cognitive test performance in 26 individuals with mild cognitive impairment (MCI) due to AD and in 26 cognitively normal individuals with an increased risk for AD due to family history, genetics, and/or subjective memory complaints. All subjects will participate in a brief stressor (public speaking and mental arithmetic) and provide saliva samples so investigators can measure stress hormone response. Then, following 2 weeks of treatment with placebo or CORT108297, in counterbalanced order, participants will complete cognitive tests assessing memory and executive function. All study participants will receive CORT108297 and placebo over the course of this 10-week trial that requires 6 in-person study visits. The primary aims will compare the effects of CORT108297 to placebo on cognitive test performance in individuals with MCI due to AD and in individuals at risk for AD, and describe the side effects of CORT108297 in study participants. Secondary aims will identify subject characteristics that predict positive response to study drug. Read Less

The investigators will aim enroll participants into our study within 3-6 months after their parent study visit so the investigators can utilize some key data points (e.g. PD-MCI diagnosis, rs-fcMRI data) from that study. PD participants will participate in a single-blind RCT with two treatment arms: process training and strategy training (Fig 4). They will complete pre-training assessment (Pre), be randomized to treatment arm (1:1 ratio stratified by sex), and then complete 8 training sessions over an 8-week period. They will return within 1 week for post-training assessment (Post) and then will complete Follow-up (FU) assessments via web or mailed survey 3 and 6 months after training ends. They will complete a 12mo FU assessment in person in conjunction with their annual parent study visit. HC participants will complete prospective memory assessment at one time point coinciding with (or within 3-6 months of) their parent study visit to determine whether any relationships observed between rs-fcMRI data and prospective memory are specific to PD.

Development of novel disease-modifying therapies for Alzheimer's disease (AD) remains of paramount importance. This study will be a Phase II randomized clinical trial testing Senicapoc in patients with mild or prodromal AD. This will be a small Proof of Mechanism study to prove biological activity and target engagement in humans with early AD. The investigators will study up to 55 patients over 52 weeks, with primary outcomes being Alzheimer's Disease Assessment Scale Cognitive Subscale (ADAS-Cog) scores and blood and cerebrospinal fluid (CSF) markers of neuroinflammation. This pilot study will provide an estimate of treatment effect size on cognitive trajectory, daily function, and brain atrophy. Read Less

The Longitudinal Early-onset Alzheimer's Disease Study (LEADS) is a non-randomized, natural history, non-treatment study designed to look at disease progression in individuals with early onset cognitive impairment. Clinical, cognitive, imaging, biomarker, and genetic characteristics will be assessed across three cohorts: (1) early onset Alzheimer's Disease (EOAD) participants, (2) early onset non-Alzheimer's Disease (EOnonAD) participants, and (3) cognitively normal (CN) control participants.

The purpose of this study is to determine whether people with MCI (Mild Cognitive Impairment) and healthy comparison subjects differ with respect to their ability to hear soft sounds and how their brain understands and processes sound. The investigators are also evaluating, within those with MCI, whether the hearing tests are associated with neurocognitive functioning. The investigators are interested in learning whether changes in cognition in those with MCI can be detected using tests of how the brain processes sound. The investigators hypothesize that participants with MCI will score worse on both hearing tests and neurocognitive tests than participants without MCI. Participants are asked to complete multiple types of hearing tests, take a series of neurocognitive tests, and complete a few questionnaires. Read Less

The goal of this clinical trial is to test the effectiveness of a pharmacist-led, primary care-based de-prescribing intervention for people living with dementia (PLWD) and the person's care partners. The intervention consists of the following strategies: 1) a de-prescribing educational brochure designed to activate the patient and care partner; 2) a single telehealth visit in which an embedded clinical pharmacist discusses the benefits and harms of the patient's medications with the patient and care partner in the context of the person's goals and preferences; and 3) pharmacist-PCP communication in which the pharmacist provides tailored de-prescribing recommendations designed to be useful and actionable for the PCP. The investigators will compare the intervention group with the waitlist control group to see if there is a difference in the primary outcome, the proportion of patients who deprescribe at least one medication by 3 months.
