NCT07571161
The main purpose of this study is to evaluate the effects of donanemab (LY3002813) versus placebo in Chinese participants who are at risk for decline of memory, language and physical ability to perform activities of daily living from Alzheimer's disease (AD). The study drug will be administered intravenously (IV) (into a vein in the arm). The study will last up to approximately 156 weeks, excluding screening.
NCT03472183
The close homology between the central and enteric nervous system suggests that a disease process affecting the central nervous system could also involve its enteric counterpart. This has already been demonstrated for patients with Parkinson's disease but needs to be proven for Alzheimer's disease. Studies on enteric nervous system during Alzheimer's disease are indeed in low number and don't have led to definite conclusion. The investigators thus propose to realize a complete analysis of the enteric nervous systems in Alzheimer's disease by studying the presence of "tau' protein, of beta-amyloid peptide,... not only by immunohistochemical but also by a biochemical approach. This study will be realized from colonic samples.
NCT06847321
This study is to test LHP588 in persons who have mild to moderate Alzheimer's disease (AD) who have shown progressive mental decline in the last year and who have P. gingivalis (Pg) infection. P. gingivalis infection has been linked to the development of dementia. LHP588 is designed to target the P. gingivalis bacterium, to potentially help to halt or slow down the progression of AD and its symptoms. A saliva test will be done to determine P. gingivalis infection. Tests for AD include standard questionnaires such as MMSE and a blood test for pTau217. Treatment will be blinded, meaning the participant and the doctor will not know if the participant is receiving LHP588 or placebo. The total time for participation in the study may be up to 64 weeks. This includes a screening period (to ensure the participant is suitable for the study and the study is suitable for the participant) of up to 12 weeks, a treatment period of up to 48 weeks, and a safety follow-up period of 4 weeks after the last dose of the study drug to check the participant's overall health. Treatment is a once-a-day capsule. Caregiver participation is required. The study requires the participant to visit the study center (with the caregiver) at least 20 times within 64 weeks (this does not include any unplanned visits that may be recommended by the study doctor). In addition, the study doctor or clinic staff will contact the participant via phone at least 1 time.
NCT06937229
The purpose of this study is to evaluate the long-term efficacy and safety of combined formulation of xanomeline tartrate/trospium chloride in an immediate release (IR) capsule (KarXT) and xanomeline enteric capsules (KarX-EC) in participants with agitation associated with Alzheimer's Disease who completed the parent studies CN012-0023 or CN012-0024.
NCT07633470
The primary purpose of this study is to evaluate the safety and tolerability of Zunveyl® over 12 weeks of routine clinical use in adults with mild to moderate Alzheimer's disease.
NCT04579120
To identify factors that signal the transition from asymptomatic (preclinical) to symptomatic Alzheimer disease (AD).
NCT06657768
The main purpose of this study is to evaluate the safety and tolerability of the study drug known as LY4006895. Part A will administer a single-ascending dose in healthy participants or Part B will administer multiple-ascending doses in participants with early symptomatic Alzheimer's Disease (AD). Blood tests will be performed to check how much LY4006895 gets into the bloodstream and how long it takes the body to eliminate it. This is a 2-part study and will last approximately 29 weeks for Part A and 61 weeks for Part B, including a screening period for each part.
NCT06223360
The purpose of this study is to learn more about the safety, effectiveness and tolerability of the study drug called Benfotiamine which may delay or slow the progression of the symptoms of early Alzheimer's disease.
NCT07361601
This study will longitudinally follow a cohort of older adults to better understand how decisions about aging in place or transitioning to long-term care-and the implementation of those decisions-are influenced by age-related changes (e.g., cognition, health literacy, chronic conditions) and social supports (e.g., caregivers).
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.
NCT04571502
Alzheimer's disease and related dementias (ADRD) are leading causes of disability and often result in communication deficits of the person with dementia (PWD) that can complicate ADRD caregiving and clinical care. The research team will work with stakeholders to develop and design a personalized Assistive and Alternative Communication (AAC) device that relies on information technology (IT) and touchscreens to promote communication and personhood for PWD about their care preferences and experiences. This study will integrate the AAC into an existing health IT intervention that already facilitates clinical communication between caregivers and providers of PWD. A clinical trial will be conducted to evaluate outcomes of 58 dyads (PWD/caregivers) and their health care provider utilizing the My PATI (My Person Assisted Touchscreen Interface)intervention as an adjunct to care and care giving for 6 months.
NCT05579236
The aim of this study is to find out whether a new image analysis technique called Cortical Disarray Measurement (CDM) could be used to help better diagnose Alzheimer's disease. This study will see whether changes on CDM can be used to identify Alzheimer's disease from a group of people living with memory and thinking problems. The study will also explore how CDM relates to changes in memory or thinking over time.
NCT05877196
The goal of this clinical trial is to test 6 months of aerobic exercise in older adults who are 65 years or older and have mild cognitive impairment (MCI) or probable/possible mild Alzheimer's Disease. The main questions it aims to answer are: * test the effects of aerobic exercise on aerobic fitness, white matter hyperintensity (WMH) volume, and patient-centered outcomes; * identify the best exercise to improve aerobic fitness and reduce non-responses over 6 months; and * examines the mechanisms of aerobic exercise's action on memory in older adults with early AD. Participants will receive 6 months of supervised exercise, undergo cognitive data collection and exercise testing 5 times over a year span, have an MRI brain scan 3 times over a one-year span, and have monthly follow-up discussions on health and wellness.
NCT06492967
Currently, 40% of global dementia cases can be prevented through lifestyle changes, with Latin America having a 56% potential reduction due to its high-risk factors. At the moment, there are no medications that halt the clinical expression of dementia. LatAm-FINGERS, a multicenter study across 12 Latin American countries, aims to study the feasibility of an intervention modifying lifestyle in individuals aged 60 to 77 at risk of dementia. Success could influence public policy on clinical care for older adults.
NCT03352258
Alzheimer's Disease (AD) is the most frequent neurodegenerative disease associated with dementia, with a constantly increasing prevalence associated with an aging population. Amyloid deposition is considered the first molecular event occurring in AD: as already showed in an animal model, a low-dose radiotherapy (RT) course is capable of reducing AD-associated amyloid-β plaques and improve cognitive function. This pilot study wishes to investigate in 10 patients with a diagnosis of prodromal or early probable AD and with evidence of amyloid pathology the effectiveness of a short course low dose RT radiotherapy to reduce amyloid deposits in the human brain using molecular imaging (18F-Florbetapir) to show the effectiveness of the treatment on the specific target.
NCT07529912
Hyperspectral retinal imaging is a non-invasive imaging modality in which a series of images of the retina are captured using light of different wavelengths. The resulting "hypercube" of data provides detailed information about retinal structure. Previous research has demonstrated a potential role for this technology in the detection of retinal amyloid beta in Alzheimer's disease. This study aims to further evaluate the use of hyperspectral retinal imaging in the assessment of individuals with dementia or those at risk of Alzheimer's disease.
NCT07548073
Alzheimer's disease (AD) is a progressive neurodegenerative disorder characterized by cognitive decline, including impairments in orientation, memory, and daily functioning. Orientation dysfunction, involving difficulties in recognizing time, place, and person, is a common and clinically significant feature in patients with mild to moderate AD. This study aims to evaluate the effectiveness of a scenario-based reenactment training program in improving cognitive function and orientation ability in patients with mild to moderate Alzheimer's disease. The intervention is based on patients' real-life experiences and uses personalized visual materials (e.g., photos and videos) to reconstruct familiar scenarios, thereby enhancing cognitive stimulation and environmental recognition. In this prospective controlled study, participants will be assigned to either a scenario-based training group or a usual care group. The intervention group will receive structured training sessions three times per week for 3 months, followed by a 6-month follow-up period. The control group will receive standard care without structured cognitive training. The primary outcome is global cognitive function assessed by the Montreal Cognitive Assessment (MoCA). Secondary outcomes include orientation function, depressive symptoms, anxiety levels, quality of life, and intervention feasibility. This study aims to provide evidence for a practical, non-pharmacological intervention to improve cognitive and functional outcomes in patients with Alzheimer's disease.
NCT05880849
The purpose of this study is to test the safety, tolerability, and effects of choline in people with increased risk of Alzheimer's Disease (AD), also known as pre-symptomatic AD. Choline is a dietary supplement, but is being investigated to see if it has any effects on the progression to AD.
NCT07545473
Hyperspectral retinal imaging is a non-invasive imaging modality in which a series of images of the retina are captured using light of different wavelengths. The resulting "hypercube" of data provides a wealth of information about the retinal structure. Our group has developed evidence supporting a role for this technology in the detection of retinal amyloid beta in Alzheimer's disease. We are undertaking further studies to establish the role of this method in the assessment of people with dementia, or those at risk of Alzheimer's disease. In addition, we wish to test whether the approach may have value in other forms of dementia or neurodegenerative disease such as Parkinson's disease, Lewy-Body dementia or vascular dementia.
NCT04855630
The purpose of this research is to see how sleep and exercise affects dementia risk over time.
