Alzheimer Disease

The purpose of this study is to see how safe LY4560736 is and to see how much and how quickly LY4560736 gets into the bloodstream. For healthy participants, the study also looks at how much LY4560736 gets into the brain. This part of the study lasts up to 13 weeks which includes staying in the Clinical Research Unit (CRU) for at least 4 days. This group will include Japanese participants, and the Sponsor may choose to enroll Chinese participants. For participants with Alzheimer's Disease, the study will also look at levels of a specific Alzheimer's-related protein in the brain and will last up to 13 weeks which includes staying in the CRU twice, each lasts about 1 to 2 days. Japanese participants, and potentially Chinese participants, may also be enrolled in this group.

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.

This pilot study will evaluate whether microsurgical modification of cervical lymphatic drainage may influence blood biomarkers and clinical outcomes in people with mild Alzheimer's disease. Thirty participants will be randomly assigned in a 1:1 ratio to either a surgical intervention group or a control group. Participants in the intervention group will undergo supermicrosurgical lymphaticovenous anastomosis (LVA) and/or lymph node-to-vein anastomosis (LNVA) in the neck to create an alternative pathway for lymphatic drainage. The procedure may be performed manually or with robotic microsurgical assistance. Participants in the control group will receive clinical observation without surgery during the first 12 months. The primary objective is to assess the change in plasma phosphorylated tau 217 (p-tau217) from baseline to 12 months. The study will also assess changes in cognitive and functional measures, including the Clinical Dementia Rating Sum of Boxes (CDR-SB), Alzheimer's Disease Cooperative Study-Activities of Daily Living (ADCS-ADL), Montreal Cognitive Assessment (MoCA), and Mini-Mental State Examination (MMSE), as well as the feasibility and safety of the surgical procedure. Participants will be assessed at baseline and at 3, 6, and 12 months. After completion of the 12-month observation period, participants in the control group may be offered the surgical procedure if they wish to undergo it.

The purpose of this Master Protocol is to support multiple studies looking at safety and tolerability of different drugs in healthy participants and participants with Alzheimer's disease, and if they remove clumps of protein (amyloid plaque) in the brain in participants with Alzheimer's Disease. Participants will enroll into either A1D-MC-AT01 (NCT07787182) or A1D-MC-AT02 (upcoming).

This randomized, sham-controlled, exploratory clinical trial will evaluate the efficacy and safety of HeLaXON, an investigational low-dose radiation therapy device, in patients with mild Alzheimer's disease dementia. A total of 30 participants will be randomly assigned in a 1:1 ratio to receive either low-dose whole-brain radiation therapy or a sham procedure using the same device. Participants in the treatment group will receive 0.04 Gy per session twice weekly for 3 weeks, for a total of 6 sessions and a cumulative dose of 0.24 Gy. Participants in the sham group will undergo the same device procedures without radiation delivery. Participants and outcome assessors will remain blinded to treatment assignment. Changes in cognitive function, dementia severity, daily functioning, and amyloid burden will be evaluated at 6 and 12 months after treatment. Safety will be assessed throughout the study. Exploratory blood biomarkers, including plasma Aβ42/40 ratio, p-tau217, and Aβ oligomer, will also be evaluated.

The goal of this pilot study is to test a combination of two non-invasive brain stimulation methods, called iTBS (intermittent theta burst stimulation) and tDCS (transcranial direct current stimulation), in people with Alzheimer's Disease (AD) and related dementias (ADRD). This study will also explore whether the combined treatment shows promise for reducing neuropsychiatric symptoms like mood swings, apathy, and agitation, and will evaluate the impact of the treatment on caregivers. The main questions the study aims to answer are: 1. Is the combined brain stimulation treatment practical and well-tolerated? 2. Do preliminary results suggest that this treatment could help manage neuropsychiatric symptoms and support a larger study? Participants will: * Attend nine in-person visits over three months. * Complete one week of in-clinic brain stimulation sessions (iTBS) followed by four weeks of daily at-home brain stimulation sessions (tDCS). * Take part in brain scans, questionnaires, and brain activity tests before and after the treatment. This pilot study is a first step to assess whether this combined treatment approach is practical and whether it has potential to improve symptoms, laying the groundwork for larger studies in the future.

Study to evaluate the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics of ARO-MAPT-SC compared to placebo in adult healthy volunteers and in participants with early Alzheimer's disease (AD), defined as mild cognitive impairment due to AD and mild AD dementia.

Alzheimer's disease is a severe neurodegenerative disorder of the brain that is characterized by progressive loss of memory and cognitive decline. With the ageing population, AD is a major public health problem affecting nearly 35 million people worldwide with numbers projected to rise to 115.4 million by 2050. AD is the only cause of death among the top ten causes that has no prevention or cure . It is believed that novel treatment of AD needs to start early or even at the prodromal stage in order to be effective. Therefore, there is an urgent need to find accurate methods of early detection before patients with AD develop clinical dementia. This study aims to identify biomarkers for AD in local Chinese population. this study hypothesizes blood-based proteomics, retinal imaging, ASL-MRP and tau PET can improve the accuracy and staging of AD.

This study aims to provide mechanistic insights into how group drumming as a music-based intervention (MBI) affects pain responses and nociceptive function in individuals with Alzheimer's Disease (AD), mild dementia or mild cognitive impairment (MCI). Heart rate (HR), heart rate variability (HRV), and brain activity will be measured during communal drumming with their dyadic partners and others. Brain activity, blood pressure, cognitive abilities, blood hormone levels, and static and dynamic pain will also be measured during sessions pre and post the 8-week community drum circle. Investigators will leverage various measurement techniques including, but not limited to, electroencephalography (EEG), quantitative sensory testing (QST), behavioral, surveys, and physiological monitoring to study the impact of group drumming on pain and brain activity in AD and inter-dyad synchrony.
