NCT05704309
The DPPOS AD/ADRD project will address the overarching question: What are the determinants and the nature of cognitive impairment among persons with pre-diabetes (PreD) and type 2 diabetes (T2D), who are a high-risk group for cognitive impairment and represent a large fraction of the United States (US) population? This U19 proposal addresses the National Alzheimer's Project Act goal to "prevent, halt, or reverse AD" in the high-risk group of persons with pre-diabetes and type 2 diabetes, who represent over half of the population aged 60 years and older in the US.
NCT05564715
This is a pilot study being done to attempt to improve episodic memory problems in persons with mild cognitive impairment (MCI) or dementia. The pre-supplemental motor area (preSMA) and dorsal anterior cingulate cortex (dACC) have been shown to play a role in episodic memory and language retrieval. Prior studies have suggested that neurostimulation targeting this region can improve episodic memory and word recall. The purpose of this study is to examine the efficacy of high-definition transcranial direct current stimulation (HD-tDCS) to the preSMA/dACC region and its influence on word retrieval and other cognitive functions in patients with MCI or dementia. Entraining the preSMA/dACC circuit with 10 sessions of HD-tDCS will allow us to study whether neurostimulation may be an effective treatment.
NCT06703541
The purpose of the study is to establish a clinical cohort for the Duke/UNC Alzheimer's Disease Research Center (ADRC). The cohort will be composed of subjects ages 25 to 44 at enrollment with normal cognition and subjects ages 45 to 80 at enrollment with normal cognition, mild cognitive impairment, or a dementia diagnosis. Initial data including demographics, medical and family history, physical exam, and neuropsychological testing will be obtained. Participants will be asked to contribute a blood sample, a urine sample, a cerebrospinal fluid sample, and undergo a MRI scan. The cohort ages 45 to 80 will be seen yearly until death to evaluate medical status, undergo neuropsychological testing and possibly collect additional samples or undergo additional imaging. All data will be de-identified and stored by the ADRC. The purpose of this study is to examine normal cognition, mild cognitive impairment and Alzheimer's disease and related dementias (ADRD) as people get older. The investigators also hope to be able to assess risk factor information of the role of genes and environmental exposures (for example health conditions, diet, and medications) in Alzheimer's disease and related disorders (ADRD) and other conditions of aging. The biological samples collected in the study will create a repository. A repository is a collection of blood and tissue samples from people with certain diseases and conditions. For the purpose of this research, the investigators hope to help researchers learn more about Alzheimer's disease and related disorders and other conditions of aging.
NCT06741865
The INSPIRE Study, initiated by the Healthy Minds Initiative, is a community-based research project aimed at demonstrating the impact of lifestyle factors on cognitive health and the prevention of dementia. Conducted in collaboration with the American College of Lifestyle Medicine, Charles Drew University, UCLA, Stanford University and Crenshaw Christian Center, this study focuses on African American communities that are disproportionately affected by lifestyle-dependent diseases. The study involves 2,000 participants aged 55 and older and aims to directly address these disparities by implementing targeted interventions to enhance cognitive function and overall brain health.
NCT03381482
In Alzheimer's disease (AD), neurofibrillary degeneration (NFD) is characterized by the intraneuronal aggregation of Tau proteins. The pathology progresses through a hierarchical pathway that may be associated with the intercellular transmission of pathology as demonstrated in our rat models. This transmission implies that Tau is actively secreted and may participate to the first steps of Tau pathology spreading. It is demonstrated in cell lines and animal models (rodents and non-human primates) that Tau is secreted not only in free forms but also in extracellular vesicles. If Tau is found in biological fluids before neuronal death it may represent an early marker of the NFD and will also define therapeutically targets. In this context, the aim is now to transfer this knowledge in humans and to decipher the nature of Tau secreted in plasma and cerebrospinal fluids collected from healthy controls to AD patients, and to decipher if the presence of tau inside vesicles is influenced by the pathology.
NCT01401582
Caring for people with dementia and treating them is a major challenge for the health care system in Germany. Among the challenges for population-based health care research are (a) identification and early recognition, (b) multimorbidity and (c) the integration of persons with dementia into the health care system. One setting which is identified to meet the challenges is the primary care setting and there especially the general physician. There have been a few interventional studies, which have been restricted to selective samples and have been conducted in inpatient settings. The purpose of this study is to test the efficacy of implementing a subsidiary support system for persons with dementia living at home. This subsidiary support system is initiated by a Dementia Care Manager (DCM), a nurse with dementia-specific advanced training. The main goals are to improve quality of life and health care of the person with dementia and reduce caregiver´s burden. The study is a general physician based cluster-randomised controlled intervention trial. A population based sample of general physicians will be asked to participate in a systematic screening trial to identify people with dementia in primary care in Mecklenburg Western Pommerania (MV), a federal state in Germany. Upon identification the people will be asked to participate in the DelpHi-MV study and after having given written informed consent will then be assigned to an intervention and a control group. Identification of people with dementia will be achieved by a short screening questionnaire in the physician's office. An extended in-depth data assessment will be conducted after inclusion into the study and then annually to measure the course of the people's health. Data assessment will be done at the people's homes. People assigned to the intervention group will receive an intervention provided by "Dementia Care Manager". The Dementia Care Manager is a specialised nurse that is going into the person's home to manage the care of dementia as well as caring for the person's relative/ or carer.
NCT05231954
The specific aim of the pragmatic trial is to evaluate the practical utility and effect of the PDM, the QDRS, and the combined approach (PDM + QDRS) in improving the annual rate of new documented ADRD diagnosis in primary care practices.
NCT05574634
A growing body of research has highlighted the importance of frontal regions, at both the functional and structural levels, in age-related declines in attentional and cognitive processing. However, the underlying neurobiological pathophysiological changes in the brain that contribute to these declines are still largely unclear. The objective of this proposal is to investigate neural mechanisms of age-related attentional distractibility, focusing on the neural circuit initiated from the locus coeruleus (LC). In the current proposal, the investigators will test the hypothesis that the neural disconnectivity of LC with the salience network (SN) drives failures of ignoring distractors in older adults. The investigators will examine how LC-SN connectivity is associated with selective attention performance, and how improved LC-SN connectivity through a cognitive training program may lead to improved attentional performance.

NCT07089303
This single-center prospective cohort study will enroll 750 participants (250 cognitively Normal (CN) individuals, 250 with mild cognitive impairment (MCI), and 250 with Alzheimer's disease (AD)). At baseline and at annual follow-ups, participants will undergo 3 Tesla (3 T) and 7 Tesla (7 T) multimodal magnetic resonance imaging (MRI) scans, blood biomarker testing, genotyping, and cognitive assessments to identify early imaging biomarkers and construct models of disease progression.
NCT05592366
The purpose of this study is to see whether an adapted questionnaire called the Care Partner Hospital Assessment Tool (CHAT) for care partners of hospitalized patients living with Alzheimer's disease and related dementias (ADRD) (CHAT-AD) can help people with dementia receive better care after they go home from the hospital. Participants will be a care partner ('family member or friend') who provides unpaid care to a hospitalized adult relative or partner to help them take care of themselves because of dementia. Participants can expect to be in this study for 14 days.
NCT03135327
The purpose of this study is to determine the clinical application of advanced ophthalmic imaging devices such as optical coherence tomography (OCT), retinal function imager (RFI), slit-lamp biomicroscopy (SLB), PERG in diseased eyes and normal controls. There are two phases in this study. The first phase is an observational phase which studies the eye in various conditions. The second phase is an interventional phase which studies the changes in the eyes after taking an over-the-counter medical food (Ocufolin) for 6 months.
NCT06631144
The purpose of the study is to develop and test the feasibility of a nonmedical digital health intervention, the Spanish-language Caregiver-Enabled Care Program (CECP), with Spanish-speaking caregivers of persons with dementia (PWD). CECP is a nonmedical digital population health intervention that provides personalized education, proactive 1:1 human coaching, and remote monitoring, all delivered via a dedicated tablet shipped to the caregiver's home at no cost to the caregiver or PWD. For this study, the investigators are recruiting 135 patient/caregiver dyads.

NCT03507790
This is a multi-center, randomized, double-blind, placebo-controlled, parallel group 36 week multicenter Phase 2 study of two doses of CT1812 in adults with mild to moderate Alzheimer's Disease (AD).
NCT07114458
The goal of this observational study is to examine if older patients who need to be under isolation precautions due to multidrug resistant bacteria or other reasons have an increased risk of suffering from delirium or cognitive decline compared to older patients without isolation precautions. To compare this, every person under isolation precautions is compared to other persons of the same age, gender, comorbidities, frailty status and hospital department. Delirium is assessed twice daily with a screening tool named 3D-CAM and cognitive performance is tested by the MOCA-Test six weeks after discharge from hospital and compared to baseline values which are assessed directly after study enrollment. The study duration for each patient participating is from the time of enrollment during hospitalization until 6 weeks after hospital discharge.
