CORT-X will examine if mitigation of stress-mediated pathogenesis of Alzheimer's disease (AD) is a feasible target for intervention in individuals at risk for this disease. This single-site (Baltimore, Maryland) phase II clinical trial is a 2-week, randomized, placebo-controlled crossover study of the effects of the selective glucocorticoid receptor antagonist, CORT108297, on cognitive test performance in 26 individuals with mild cognitive impairment (MCI) due to AD and in 26 cognitively normal individuals with an increased risk for AD due to family history, genetics, and/or subjective memory complaints. All subjects will participate in a brief stressor (public speaking and mental arithmetic) and provide saliva samples so investigators can measure stress hormone response. Then, following 2 weeks of treatment with placebo or CORT108297, in counterbalanced order, participants will complete cognitive tests assessing memory and executive function. All study participants will receive CORT108297 and placebo over the course of this 10-week trial that requires 6 in-person study visits. The primary aims will compare the effects of CORT108297 to placebo on cognitive test performance in individuals with MCI due to AD and in individuals at risk for AD, and describe the side effects of CORT108297 in study participants. Secondary aims will identify subject characteristics that predict positive response to study drug.

The Alzheimer's disease (MY) is a major problem of public health. The French National Database Alzheimer ( BNA) registers(records) all the medical acts made by units of memory(report) and of independent specialists in France. In 2008, the national Plan Alzheimer 2008 - 2012 had for objective to strengthen the search(research) on the Alzheimer's disease (MY) and for related disorders(confusions), to promote an early diagnosis and to improve at the same time the management of the patients and to support careers(quarries). A specific part(party) of this plan gave rise to the creation of the French national database Alzheimer ( BNA) to supply epidemiological data as well as indicators of activity. Since 2009 The information collected(taken in) in the BNA consists of a set(group) limited by data (CIMA of information minimum Corpus Alzheimer) concerning the demographic, clinical and diagnostic data defined by national consensus. The number of variables is limited to facilitate and to improve the participation in this national database. The participants are the Centers Report (CM)((LECTURE)) and Center Memory(Report) of Resources and Search(Research) (CMRR) and independent specialists. In 2015 more than 500 Centers send CIMA to the BNA. The plan Disease Neurodegenerative 2014 - 2019 wishes to pursue and to amplify the BNA.

The main purpose of this study is to determine if participants who previously took donanemab get clinical benefit when they receive annual doses. For each participant, the study will last up to 2.5 years and will include 6 visits.

This is a Phase 1, multicenter, randomized, double-blind, placebo-controlled, multiple dose-escalating trial to evaluate the safety, tolerability, and immune response of AV-1980R, an investigational vaccine targeting tau protein, in participants with preclinical Alzheimer's disease. Up to 48 cognitively unimpaired adults aged 65-80 with biomarker evidence of early Alzheimer's disease will be enrolled into three ascending dose cohorts. The study is designed as a secondary prevention trial to test whether therapeutic immunization at the preclinical stage is safe, induces an immune response, and, exploratorily, may favorably affect biomarkers associated with disease progression.

Alzheimer's disease (AD), the most common cause of dementia, is a progressive neurodegenerative disorder characterized by cognitive decline, including impaired learning ability, memory loss, and behavioral disturbances. According to surveys conducted by the Ministry of Health and Welfare in Taiwan, the prevalence of dementia among individuals aged 65 years and older was estimated at 7.86% in 2018, affecting more than 280,000 individuals, and is projected to approach 900,000 by 2065, resulting in substantial medical, social, and economic burdens. Current pharmacological treatments provide only limited symptomatic benefits and may be associated with adverse effects. Therefore, safe and effective non-pharmacological interventions that may support cognitive function and reduce caregiver burden are urgently needed. Experimental studies suggest that far-infrared (FIR) irradiation may enhance mitochondrial oxidative phosphorylation, increase ATP production, and promote microglial amyloid-β clearance, which may help delay the progression of Alzheimer's disease. This trial aims to investigate the safety and effects of far-infrared (FIR) therapy on cognitive function in patients with Alzheimer's disease. The findings may support the clinical application of FIR therapy as a non-pharmacological intervention to improve cognitive function and quality of life, reduce medication burden and treatment-related side effects, lessen caregiver burden, delay institutionalization, and reduce the social and economic burden associated with Alzheimer's disease.

Reducing injected dose and/or acquisition time in amyloid PET imaging would improve comfort, radiation safety and cost-effectiveness in diagnosis and follow-up of patients. This study evaluates the impact of a deep learning-based noise reduction algorithm on visual analysis and Centiloid quantification when simulating reduced injected doses of \[18F\]flutemetamol.

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 study seeks to evaluate the utility and efficacy of the Non-Contact Sleep Quality Monitor System when used to monitor the sleep quality of individuals living in long-term care (LTC) with either Alzheimer's Disease (AD) or Alzheimer's Disease Related Dementia (ADRD). This before-after comparison trial will be conducted in several LTC facilities to evaluate the effect access to System Sleep Quality Data has on documentation of sleep disorders or treatments and sleep quality change over time for AD/ADRD participants in the intervention group as compared to the control group. All subjects will undergo sleep quality monitoring for 4-weeks. At the end of the first 2-weeks, research staff and LTC facility staff and medical providers will receive access to sleep monitoring data. We hypothesize that when real-time System Sleep Data is shared with LTC staff or healthcare providers, that sleep disturbances will be more readily detected, leading to timelier, better tailored treatment interventions for sleep disturbances, thereby improving sleep quality and decreasing daytime physical inactivity.

A3D is a phase I/II clinical trial. The primary objective is to evaluate the safety of allogeneic adipose tissue derived-stem cells (AdMSC) administered by intravenous (IV) route in mild to moderate Alzheimer disease (AD) using a dose escalation protocol.

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.

Progressive age-related cognitive deficits occurring in both AD and DS have been connected to the degeneration of several neuronal populations, but mechanisms are not fully elucidated. The most consistent neuronal losses throughout the progression of AD are seen in cholinergic neurons where these losses negatively affect cognition, particularly in attention, learning, and memory formation. Evidence of reduced cholinergic integrity in DS is largely limited to animal models and post-mortem human data. The investigators propose to use molecular, functional, and structural biomarkers to assess the cholinergic integrity in adults with DS. The investigators anticipate using the data gathered in this pilot study to inform future study designs to determine AD risk stratification in DS by identifying individuals who show an accelerated decline in cholinergic integrity that correlates with cognitive and neurobehavioral changes. Also, our cholinergic biomarkers may identify whether individuals with DS are likely to respond to pro-cholinergic interventions, including the novel cholinergic modulators that are being developed to enhance cholinergic-sensitive cognitive functioning. The investigators anticipate using the data gathered here to inform future treatment studies in TRC-DS and beyond where novel cholinergic treatments may offer opportunities for early intervention in DS and be complementary to disease-modifying approaches such as anti-amyloid treatments.

This project aims to study on one hand the early mitochondrial alterations, common or specific, occurring in peripheral cells of patients with Alzheimer's disease or related dementia and, on the other hand, identify the metabolomic biomarkers that may be at the origin of mitochondrial disturbances associated with the disease. This will be the first study combining functional analyses of mitochondria and exploratory metabolomic assessments in the same cohort at early stages of the disease.
