Active clinical trials for "Alzheimer Disease"

Alzheimer's disease (AD) is a prevalent, long-term progressive degenerative disorder with great social impact. It is currently thought that, in addition to neurodegeneration, vascular changes also play a role in the pathophysiology of the disease. Meantime, EEG resting state has also demonstrated significant change in patients with AD in neuroscience research area. Thus, the combination of these sensitive biomarkers would lead to a potential new biomarker for detection of AD, which has higher specificity and sensitivity.

The study will investigate structural and functional characteristics of the brain of dementia patients compared to healthy controls in order to get a better insight into importance of early biomarkers for the diagnosis of Alzheimer's dementia. The methods for obtaining biomarkers incude magnetic resonance imaging (MRI), near-infrared spectroscopy (fNIRS) and electroencephalography (EEG), electrocardiography (ECG) and neurophyshological assessments. Special parameters are being studied that have already been shown to detect changes in the early stages of Alzheimer's dementia.

This study aimed to investigate relationship between cognitive function and functional mobility in Alzheimer's disease.

The neurological disorders that accompany aging represent a major public health problem. The management of these diseases is a major medical and social priority. This project is based on the assumption that the oral cavity represents a privileged observation space to address these issues. The mouth is a site of easy access for painless sampling; there is therefore a major interest in identifying early oral infectious markers of the development or evolution of senile dementia. In addition to the interest of an early oral diagnosis, the mapping of the oral microbial flora in the demented elderly would allow a better understanding, prevention or even control of the evolution of neurodegenerative diseases. The final objective of our approach is to characterize the oral pathogens, or more probably the group of oral pathogens, which are significantly associated with Alzheimer's disease.

This study is designed to document the loss of sociomoral emotions (like empathy, guilt, and embarrassment) in patients with behavioral variant frontotemporal dementia. The loss of these emotions, which function as the motivators for social behavior, will manifest in specific interpersonal behaviors. These behaviors will correlate with regional changes in regional changes in medial frontal and anterior temporal lobes. These social and emotional changes will be compared with a young-onset Alzheimer's disease comparison group.

The purpose of this study is to determine the predictive value of standardized cognitive tests performed in health examination centres for the diagnosis of Alzheimer's disease and related disorders among adults aged 65 years and older with a subjective memory complaint.

The main goal of this project is to use imaging and biomarkers to identify cognitively normal elderly people who are at increased risk for developing mild cognitive impairment (MCI). MCI is the earliest clinically detectable evidence for brain changes due to Alzheimer's disease (AD). The second goal of this project is to describe the inter-relationships among anatomical biomarkers, cerebrospinal fluid biomarkers, and cognition measures in those elderly people who develop MCI.

The prevalence of Mild Cognitive Impairment (MCI) is about 15%-17%. 10%-15% of MCI progresses to Alzheimer's disease (AD) every year. The annual incidence of MCI in the normal elderly is about 1%. Peripheral Blood biomarkers is the key and difficult points in AD research. Except expensive brain β amyloid plaque imaging, few breakthroughs of early diagnosis technology of MCI due to AD can be made to facilitate clinical application. Even Tau-181 and Tau-217 were reported in this year on Lancet neurology and JAMA. We also need to study on the biomarkers upstream of pathological changes about senile plaque. The purpose of this program is to study the reliability and validity of plasma miRNAs for early diagnosis of MCI due to AD and other dementia such as DLB and FTLD. The clinical diagnosis of AD and MCI due to AD are according to the National Institute of Aging and the Alzheimer's Disease Association (NIA-AA) diagnostic criteria in 2011. Plaque imaging is used to be golden criteria for the diagnosis of AD and MCI due to AD.

ECOCAPTURE@HOME is a study which is currently being developed with the objective to capture the behavioral signature of apathy in everyday life context through remote monitoring of participants' behavior for about one month. Participants will not only be patients with apathy but also their spouse caregiver. Behavioral markers of apathy will be extracted from a combination of: 1/ objective physiological data from sensors on a bracelet worn by participants; 2/ subjective data filled by the caregiver through an application. Thus investigators will collect a pool of metrics and show they can measure three assumed behavioral markers of apathy (daytime activity, quality of sleep and emotional arousal), which in turn allow to predict caregiver's perception of the dyad's psychological state. The final goal is to lay the foundations for the development of a clinical tool for the remote follow-up of patient-caregiver couples.
