Dementia Clinical Trials

The goal of this clinical trial is to demonstrate potential improvements in clinical trial methods relating to dementia and cognitive decline. The main questions it aims to answer are: * Can an intervention's outcome be better assessed by a latent variable ("δ") integrating cognitive performance with functional status? * Can latent biomarkers of δ guide the selection of an intervention that will modulate dementia severity? * Can a latent variable, derived from information collected remotely from caregivers, preselect subjects most likely to respond to the intervention? * Is the effect of the intervention in fact medicated by changes in the targeted biomarker? In this case, the biomarker will be a latent variable derived from several proteins measured in blood (i.e., so-called "adipokines"). The intervention will be donepezil, a medication approved for the treatment of Alzheimer's Disease, but only recently associated with adipokine changes. Participants with cognitive impairment and their caregivers will be interviewed by telephone and those newly prescribed donepezil by their provider for cognitive impairment will be recruited and enrolled. On the basis of the caregiver's report, the cognitively impaired subjects will be assigned to two groups based on a prediction of their response to donepezil. Researchers will compare those groups to see if dementia severity, as measured by δ, improves in predicted responders, and whether the change in the d-score is mediated by changes in adipokines.

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. Read Less

It is generally acknowledged that patients with dementia are best cared for at home. However, outbursts of various behavioral disturbances, e.g., combativeness, appear in most cases and often necessitate institutionalization. These outbursts are often without apparent warning, which limits preventive interventions. The measurement of the electrical activity of the skin is well-studied as an indicator of stress or agitation. The investigators propose to monitor the electrical activity of skin in patients with dementia in order to determine whether any sign of agitation may occur before the outburst. If skin electrical activity gives sufficient warning, then preventive interventions may be tried. If successful, the ability to predict and prevent outbursts of behavioral disturbances will allow patients to be cared for at home for longer periods. It is the primary aim of this project to determine whether skin electrical activity gives such a warning; possible preventive measures will be the subject of future studies. Read Less

Cognitive impairment related to dementia is frequently under-diagnosed in primary care settings. This problem is more prevalent in health disparities populations. The investigators developed the 5-Cog brief cognitive assessment that is simple to use, standardized, takes \<5 minutes, does not require informants, and accounts for major technical, cultural, and logistical barriers of current assessments. The investigators propose a hybrid Type 1 effectiveness-implementation design in real-world settings to adapt and test the effectiveness of the 5-Cog paradigm to increase detection of cognitive impairment care in older adults presenting with cognitive concerns. The study aim is to evaluate, using a pragmatic cluster-randomized trial design, the effectiveness of the 5-Cog paradigm to increase 'incident cognitive impairment' detection (new MCI and dementia diagnoses) relative to enhanced usual care in 6,600 older patients presenting with cognitive concerns in 22 primary care clinics in Bronx and Indiana. As diagnosis without action will not improve patient care, 'improved dementia care' will be examined as a secondary outcome. Results will also be examined in NIH designated health disparity populations including underserved minority and socio-economically challenged populations. Read Less

The goal of this pragmatic, embedded clinical trial is to analyze the implementation of Patient Priorities Care in primary care and geriatrics clinics with patients living with dementia or mild cognitive impairment. This study aims are: * demonstrate the feasibility of using the electronic health record to identify a diverse cohort of eligible patient and patient-care partner dyads who will engage in a Patient Priorities Care conversation with a trained facilitator. * demonstrate feasibility of pragmatically assessing clinical outcomes using the electronic health record, including a) number of days at home, b) total medications, and c) new referrals to specialist physicians. * examine key feasibility measures across racial, ethnic, and socioeconomic subgroups. Participants will receive a packet of information about Patient Priorities Care from their primary care clinic, in advance of their next upcoming clinic appointment. Individuals who receive a packet will have the opportunity to engage in a conversation about what matters most to them and what their priorities are, with trained facilitators at the clinic.

The prevalence of Alzheimer's Disease (AD) is rising, but existing medications provide only modest control of cognitive decline and associated symptoms, and novel therapies are urgently needed. This randomized sham-controlled trial will determine if an innovative low-risk remotely-supervised transcranial Direct Current Stimulation (tDCS) applied over the area of the dorsolateral prefrontal cortex for 30 minutes at the intensity of 2 mA five times per week for 6 months at home can improve cognitive performance and symptoms and modulate neuroimaging markers of neuroplasticity in 100 patients with mild to moderate AD. If effective, this novel intervention can substantially enhance AD symptom management at home, improve quality of life of AD patients and their families, and reduce burden associated with this debilitating illness.

As our population ages, more older adults face motor-cognitive declines, increasing their risk of falls and fear of falling. Exercise is an effective way to maintain cognitive function, as supported by recent studies. However, those with poor motor and cognitive abilities often struggle to visit rehabilitation centers, leading to high dropout rates and low adherence to unsupervised programs. A remote exercise program tailored for individuals with cognitive impairments is urgently needed to preserve cognitive function, promote independent living, and reduce related costs. Researchers aim to develop an in-home system for adults with mild cognitive issues or dementia, designed to improve balance and cognition while being remotely supervised through telemedicine.

Building upon prior work, the investigator team developed a communication intervention for older adults with ADRD who are considering a decision about cancer management (adapted intervention: COACH-Cog). The investigators hypothesize that for patients with dual diagnoses of ADRD and cancer, COACH-Cog will increase autonomy support of care partners and patients in the decision-making process, leading to greater acknowledgement and support of cognitive concerns and cognitive-related goals, thereby improving goal concordant care. The investigators are conducting a pilot randomized controlled trial (RCT; cluster randomized by physician) including approximately 45 oncology clinicians and 130 patient/care partner dyads evaluating the effect of COACH-Cog on care partner and patient autonomy support, care partner well-being, goal-concordance, and communication.

The primary objectives are to: 1. To determine whether MIB-626, after its daily oral administration, penetrates the blood-brain barrier in humans by measuring the cerebrospinal fluid (CSF) concentrations of MIB-626 and its key metabolites, nicotinamide (NAM), NR, 2-PY, and MeNAM at baseline and on day 90 at steady state. 2. To evaluate whether oral MIB-626 administration engages the sirtuin-NAD pathway by determining the abundance of NAD (a SIRT1 substrate) in the brain using ultra-high field 7T magnetic resonance spectroscopy and in peripheral blood mononuclear cells using a validated LC-MS/MS assay. 3. To determine whether MIB-626 alters the circulating biomarkers of aging that the geroscience experts have recommended (HbA1C, IGF1, T3, IL6, TNF, and urinary F2-isoprostane). Read Less

This pilot feasibility study will be a randomized control trial of usual care following Intensive Care Unit (ICU) discharge compared to the Anticipating Decline and Providing Therapy (ADAPT) screening and support intervention. The trial aims to enroll 120 older adults (age 60 or older). Read Less

Studies have shown that ethnic-racial minority elders are more likely to be neglected from appropriate dementia care in time than the white counterparts. Among minorities group, Korean Americans (KAs) are the 4th largest and one of the most rapidly growing Asian subpopulations and have been characterized as under-resourced and underserved population of dementia care. This research is being done to understand how an education and navigation support program led by trained community health workers (CHWs) helps Korean American elders with probable dementia and the Korean American elders' caregivers. In a 2-arm randomized controlled trial (RCT) with 288 dyads, the investigators' aims are to (1) test the effect of a community-based intervention delivered by trained CHWs for undiagnosed KA elders with probable dementia and the KA elders' caregivers, (2) evaluate the effect of the PLAN on improving caregiver's dementia literacy, self-efficacy in dementia care and service use, social support, depression, and quality of life at 6 months in comparison to usual care, and (3) examine whether the effect of PLAN differs across age, sex, English proficiency and education caregiver subgroups. Exploratory Aim 1 is to test the effect of PLAN on Korean elders with probable dementia and caregiver development of a plan regarding dementia care at 6 months in comparison to usual care. The other two Exploratory Aims are to test the applicability of this study in another environment: Exploratory Aim 2: Using an equity-informed human-centered design framework, scale PLAN for implementation in ethnic daycare and Exploratory Aim 3: Pilot test the feasibility and acceptability of PLAN in ethnic adult daycare. Aim 1 and Exploratory Aim test the following hypotheses: (1) Korean elders with probable dementia who receive the PLAN will have higher rates of linkage to medical service for dementia than those in the control group (Aim 1) and (2) Korean elders with probable dementia and the KA elders' caregivers who receive the PLAN will have higher rates of having a plan for dementia care than those in the control group (Exploratory Aim). Aim 2 tests the following hypothesis: Caregivers in the PLAN group will have higher dementia literacy, self-efficacy in dementia care and service use, social support, and quality of life, and lower depression than those in the control group.
