Active clinical trials for "Alzheimer Disease"

Hope Biosciences is conducting a research study of an investigational product called autologous adipose-derived mesenchymal stem cells (abbreviated as HB-adMSCs) as a possible treatment for Alzheimer's disease (AD). The study purpose is to evaluate the safety profile of four IV infusions of HB-adMSCs in subjects with clinical diagnosis of AD.

Alzheimer's disease (AD) is the most common form of neurodegenerative disorders leading to dementia. Currently, there has been no effective pharmacologic therapy for this disease. Electroencephalogram-based neurofeedback is considered as a potentially treatment strategy. In this project, the investigators aim to investigate the effectiveness of neurofeedback therapy on cognition for individuals with subjective cognitive decline (SCD). Participants will receive electroencephalogram-based neurofeedback therapy once a day for successive five days. Then, the investigators will evaluate the changes of memory function between baseline and post-therapy visits.

Alzheimer's disease (AD) is the most common form of neurodegenerative disorders leading to dementia. Currently, there has been no effective drugs targeting this disease. Functional food is considered as a potentially non-pharmacologic treatment. In this project, the investigators aim to investigate the effectiveness of a mixed functional food with main compositions of ginsenoside, green tea polyphenols and marine collagen peptide on cognition for individuals with subjective cognitive decline (SCD). Taking the randomized, double-blind, placebo-controlled method, participants in the functional food group will take mixed functional foods for three months and those in the placebo group will take placebo. After that, the investigators will investigate the changes of cognitive function. Furthermore, based on the neuroimaging technique, the regulatory mechanism of functional food in intervening SCD will be revealed from the perspective of altered brain functional activity. In conclusion, these results are beneficial for understanding the therapeutic effect of mixed functional foods as a non-drug treatment for early AD and further elucidating the potential brain mechanism, which are of great values in solving scientific and clinical practice issues.

This is a randomized sham control study to evaluate how repetitive Transcranial Magnetic Stimulation (rTMS), interactive cognitive training, or the combination of rTMS and cognitive training reduce the cognitive decline of patients diagnosed with Alzheimer's disease

Alzheimer's disease (AD) is the most common cause of dementia and its prevalence will multiply in the coming years, so it is urgent to establish preventive and therapeutic measures. AD it is characterized by cerebrovascular and parenchymal accumulation of protein deposits enriched in amyloid-beta (Aβ) as a consequence of alterations of the blood-brain barrier. More than 60% of plasma Aβ is associated with triglyceride-rich lipoproteins (TRL), being higher in subjects with AD. Microglia act as resident macrophages and play a crucial role in most neuropathologies, since it is activated after homeostasis impairment in the brain, and surrounds amyloid plaques in patients with AD. As a result of microglial activation, a large number of pro-inflammatory markers are released, mediated by alterations in the redox state, through the generation of ROS by the complex NADPH oxidase. In a previous study, the investigators demonstrated in BV-2 cells that artificial TRL are capable of activating microglia and trigger an inflammatory process. In addition, the investigators showed that some of lipophilic minor components of pomace olive oil simultaneously modulate oxidative stress and the inflammatory response in microglia. The investigators suggested that these results should be replicated in humans after consumption of pomace olive oil. Therefore, in the present study we formulate the hypothesis that human TRL are capable of activating microglia and that such activation can be attenuated when those particles are generated after consumption of pomace olive oil. The results of the study would lay the foundation for the start of clinical trials demonstrating the effect of pomace oil in reducing the risk of development and progression of AD.

This protocol is designed to standardize imaging studies using florbetapir F 18 PET to provide information on amyloid burden in subjects participating in other studies (companion protocol) such as longitudinal studies of aging and studies of biomarkers for neurodegenerative diseases.

This study is designed to test the relationship between measurements of brain amyloid using florbetapir F 18 PET imaging and true levels of amyloid plaque density as measured by histopathological assessment. The study will address the following specific aims: To expand the number of subjects included in the A07 (NCT00857415) trial correlation analysis (measuring the correlation between the global visual rating of brain amyloid plaque density on an independent blinded read of the florbetapir F 18 PET scan and the cortical amyloid plaque density at autopsy as assessed by histopathology for subjects in the autopsy cohort). To determine the sensitivity and specificity of an independent blinded visual read assessment of the florbetapir F 18 PET scan (Aβ+ or Aβ-) versus the final blinded neuropathological assessment made at autopsy.

The aim of this study is to examine the relationship between plasma putative biomarkers for Alzheimer's disease (i.e. Ab40 amyloid and total Ab42 amyloid, free, bound, free/bound, truncated, sAPPα) and : the risk of conversion of individuals with Mild Cognitive Impairment (MCI) into Alzheimer's disease (AD), the Alzheimer's disease progression rate.

Empathy, defined as the ability to understand others emotions, is a fundamental concept in social interactions. It is a psychological phenomenon involving various separable components : (i) the ability to feel and imagine the emotions, (ii) the ability to adopt the perspective of other people. Several neurological diseases with behavioral disorders may lead to impaired processing of social and/or emotional informations. These pathologies are likely to induce a lack of empathy that may result from impairments at different levels. The objective is simply to study how others' emotions are understood and how this allows for regulation of personal behavior. This study is being carried out among patients seen for various health problems and who can make behavior changes. This study could help to understand some neurological diseases and thereby to identify them earlier and/or to better differentiate them.

The study will evaluate the safety & efficacy of AC-1204, a ketogenic compound, administered orally on a daily basis for 6 months. Following the 6 month double-blind phase of the study, subjects may enroll in an optional 6 month open-label extension phase. Efficacy will be evaluated by standard tests of memory and cognition, along with other measurements of activities of daily living and quality of life. Safety will be assessed by frequency of adverse events and changes in laboratory test results. Subjects will be stratified and outcomes will be separately analyzed based on apolipoprotein E4 genotype (APOE4).
