NCT04294888
The purpose of this study is to assess the effects of non-invasive brain stimulation on memory in cognitively unimpaired older adults and in patients amnestic mild cognitive impairment (aMCI) due to Alzheimer's disease (AD). This study will use repetitive Transcranial Magnetic Stimulation (rTMS) to stimulate nodes of the Default Mode Network (DMN)- which is thought to support episodic memory and to be affected by Alzheimer's pathology. We will use functional connectivity MRI (fcMRI) to assess changes in functional network architecture following the stimulation. We will also assess putative cognitive improvements resulting from the stimulation by in-depth memory testing.
NCT06680154
The goal of the present studies is to develop and validate novel stimulation protocols for the entrainment of gamma oscillations, which are associated with many cognitive functions and critically involved in cognitive impairment such as Alzheimer's disease. In this proposal, combination of repetitive transcranial magnetic stimulation (rTMS) and transcranial alternating current stimulation (tACS), which has been shown effective for the induction, and stabilisation of alpha and theta frequencies in our forgoing studies, will be adopted to the gamma frequency range and applied on prefrontal regions as well as model-based cortical areas to enhance and stabilize gamma oscillations, thereby facilitating cognition
NCT04123314
This open-label pilot study examines whether the hallucinogenic drug, psilocybin, given under supportive conditions, is safe and effective for depression in people with Mild Cognitive Impairment (MCI) or early Alzheimer's Disease (AD). This study will also assess whether psilocybin may improve quality of life in those individuals.
NCT07178210
The objective of this investigational device exemption (IDE) study is to evaluate the safety and feasibility of using the Symani System and microsurgical techniques in the deep cervical lymph node (dCLN) region in the setting of mild to moderate Alzheimer's disease and lymphatic abnormalities.
NCT05508789
The reason for this study is to assess the safety and efficacy of donanemab in participants with early Alzheimer's disease. The study duration including screening and follow-up is up to 93 weeks.
NCT04404153
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.
NCT04863495
This is a longitudinal study with regular quantitative assessments of all participants every six months for 3 years. The quantitative portion of the study will recruit couples, consisting of individuals over the age of 65 who are in a committed relationship. Both members of the couple must be willing to participate at baseline. The assessment is in two parts. In the first part, each member of the couple will be asked the following: demographic information, mental health history, self-reported physical and emotional health, measures of emotional and mental health, personality, relationship and attachment style, social support and self-efficacy. Then each member of the study couple will be asked a series of questions to determine whether they consider themselves a caregiver. If they do, individuals will be asked to respond to additional caregiver questionnaires. Follow-ups will occur every six months for the study couples for a total of three years from the baseline visit. Each visit, the entire assessment except for demographic questions, will be re-administered to each individual in the couple. At the end of each questionnaire battery, individuals will be screened for cognitive impairment and those who are in the middle to advanced stages of dementia will no longer participate. Recruitment will end when 600 individuals (300 couples,150 couples at each site) are enrolled in the longitudinal portion of the study. All study visits will be conducted virtually via Zoom or WebEx video conferencing. Analyses will be conducted to determine the association between changes in dyadic relationship and changes in mental health and cognitive outcomes, to elucidate how relationship characteristics impact health and well-being as perceived by each member of the dyad.

NCT07314190
This is a retrospective observational study to evaluate the clinical utility of blood-based biomarkers in the diagnosis and management of patients with a neurodegenerative disease (ND) or mental disorder (MD).
NCT07420075
The design is an open-ended, prospective, observational, (non-interventional) registry for subjects with mild cognitive impairment (MCI), early symptomatic Alzheimer's disease, Alzheimer's disease, or dementia with clinical suspicion of Alzheimer's disease under the care of a neurologist, psychiatrist, geriatrician or other qualified provider. Longitudinal data are collected from subjects, their care partner(s), and their treating healthcare provider during routine clinical encounters using a structured and standardized data collection method. Approximately 2,000 subjects, with no defined upper limit, across around 75 clinical sites worldwide will be recruited.
NCT03507257
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.
NCT05178992
The objective of this study is to demonstrate the impact of a socially assistive robot system on reducing apathy among cognitively impaired older adults residing in long term care facilities. Earlier phases of this project demonstrated the feasibility and acceptability of the robotic system. First, investigators will improve the social robotic interaction architecture through additional software development, enhance its versatility, and make it easy for non-experts to run. Second, 188 participants will be randomized to either usual activity programs at the long term care facility, or the usual activity programs plus the robotic activities. Researchers will examine the effect on apathy and also plan on examining underlying individual and facility factors that influence the impact of the robotic activities.
NCT06514001
The purpose of this study is to assess safety, tolerability, plasma pharmacokinetics and biologic activity of a single intravenous dose of AMDX-2011P in participants with Alzheimer's Disease (AD).
NCT06801639
Participants will be asked to participate in this research study of a device that creates transcranial direct current stimulation (tDCS). The researchers hope to learn if 30 minute sessions of transcranial direct current stimulation (tDCS) improve such a mood or feelings in people with Alzheimer's Disease. This study involves the use of an investigational device called a tDC stimulator. "Investigational" means that the device has not yet been approved by the U.S. Food \& Drug Administration (FDA) for treating Alzheimer's Disease. This study will help find out what effects, good and/or bad, this has. The safety of this device in humans has been tested in prior research studies; however, some side effects may not yet be known.
NCT06021704
Care for America's Aging is a randomized pilot study investigating whether a home health aide training intervention consisting of enhanced dementia-specific curriculum content will improve: 1) behavioral symptoms of older adult persons living with dementia or cognitive impairment (PLWD/CI) and 2) global health-related quality of life among PLWD/CI and their care partners.
NCT07222449
By 2025, Taiwan will become a super-aged society, with the number of Alzheimer's disease patients continuing to rise. However, the vast majority of dementia patients experience "behavioral and psychological symptoms of dementia" (BPSD), such as circadian rhythm disruptions and sleep disorders, which are not only difficult to assess accurately but also lack safe and effective treatments. If "wearable devices" can be accepted by elderly dementia patients, they may bring groundbreaking changes to both assessment and treatment approaches. This project builds upon previous research and outcomes funded by the National Science and Technology Council (NSTC), the Ministry of Education, and the UK Alzheimer's Research UK (ARUK). Over four years, the project will begin by exploring "digital inclusivity" to validate the feasibility of research-grade actigraphy devices for dementia patients in Taiwan and establish a prototype research platform for wearable devices for these patients. Subsequently, in collaboration with Harvard University, the project will conduct a double-blind, randomized clinical trial to evaluate the efficacy of wearable photobiomodulation (PBM) devices in improving sleep, circadian rhythm disturbances, and other BPSD, as well as assess the user experience of integrating these two devices into a "digital therapy" model for both patients and caregivers. Finally, the project will integrate wearable device data, patient clinical symptoms, and longitudinal results from four years of tracking the latest Alzheimer's blood-based biomarkers. In collaboration with Europe's largest remote dementia care team, RADAR-AD, the project will analyze potential digital phenotypes of dementia, explore the interactions among circadian rhythm disturbances, cognitive decline rates, and biomarkers, and establish a three-dimensional assessment model for dementia patients encompassing "clinical symptoms (both cognitive and non-cognitive)," "lifestyle and functionality," and "biological markers." This innovative approach aims to provide a more comprehensive understanding and treatment of dementia.
NCT03682081
The overall purpose of this project is to develop effective dysphagia rehabilitative interventions for patients with Alzheimer's Disease and related dementias at risk for pneumonia development.
NCT06880510
The locus coeruleus (LC) has recently been identified as one of the earliest sites of damage in AD with pathological lesions appearing as early as the mid-20s. In this study, the investigators use a variety of techniques including structural MRI, functional MRI, pupillometry, and transcutaneous vagus nerve stimulation to assess the health of the LC and its relation to easily measurable peripheral variables.
NCT06057909
The purpose of this research study is to investigate how the brain, memory, thinking, and motor behavior change both in individuals with movement and/or cognitive disorders, as well as healthy individuals. Researchers will look at measurements of memory, thinking, brain wave and muscle activity, daily functioning, and brain scans to learn more about brain disorders such as Alzheimer disease and Lewy body disease.
