Active clinical trials for "Alzheimer Disease"

EYE-TAR(AD+) is an observational study based on the same design as the princeps EYE-TAR(MA) study, but with a larger number of patients and including an additional evaluation of Facial emotion recognition (based on a more ecological material), in order to reinforce conclusions of the study EYE-TAR(MA) https://doi.org/10.1016/j.npg.2020.08.003. The main objective is to confirm that facial emotion recognition can be improved in AD using the "Training of Affect Recognition program" (TAR). The Secondary Objectives are to: Evaluate the impact of the "Training of Affect Recognition program" (TAR) on oculomotor behavior in a situation of social cognition, on behavioral disorders and on caregiver burden. Confirm that improvement in facial emotion recognition is related to modification of observation strategies. Confirm the link between improved recognition of facial emotions, reduced behavioral disorders and caregiver burden.

The main objective of the research is to create a tool that can make a good diagnosis of cognitive abilities in Alzheimer's patients. As a secondary objective, the investigators intend to examine both the percentage of correct answers and the response times and see their relationship with age, gender, sex, months since the onset of the disease and years of training.

This is a non-randomized, non-treatment, observational study designed to discover correlations between retinal imaging and amyloid PET imaging. Subjects will be recruited to the clinical cohort from referring physicians. Subjects may be participants from existing studies and clinical practices

The goal of this study is to examine olfactory function in preclinical subjects or individuals with neurological diseases such as Probable Alzheimer's Disease (PRAD), Frontotemporal Dementias (FTD), Dementia with Lewy Bodies (DLB), Traumatic Brain Injury (TBI), and Amyotrophic Lateral Sclerosis (ALS).

This research will be achieved by the assessment of p75NTR-ECD expression (total and linked to different species of Aβ (Aβ1-40 and Aβ-1-42)) within the cerebrospinal fluid (CSF) of patients with AD dementia, mild cognitive impairment (MCI) due to AD, frontotemporal dementia and non-neurodegenerative dementia.

This study aims to predict cognitive decline using a performance endophenotype of neuro-feedback based on functional magnetic resonance imaging in real time in a population at risk for Alzheimer's disease (AD).

Near 40% of French people aged 65 years and over and suffering from Alzheimer disease and associated disorders (ADAD) are exposed to antidepressants (AD) versus 13% of those without ADAD. If depression and anxiety disorders are comorbidities frequently associated with dementia, such level of AD exposure suggests an overuse of AD in this population. Hypothesis: Overuse of AD is frequent in patients with ADAD. It is possible to assess overuse associated with off label prescriptions (no validated indication and excess in prescription duration) Main objective: to assess the prevalence of AD overuse associated with off label prescriptions (no validated indication and excess in prescription duration) in patients aged 70 years and over with ADAD. Secondary objectives: To assess the prevalence of AD prescribed for a non validated indication To assess the prevalence of AD prescribed with excess in prescription duration To assess the prevalence of psychotropic coprescription and notably the prevalence of the neurologic iatrogenic alerts as defined by the French National Authority for Health To assess factors associated to AD overuse Method: A transversal monocentric study in the geriatric day Bretonneau unit will be performed. Study will be proposed to all eligible patients (with non-opposition of the patient or of his legal representative to the collection of his personal data). Included people will have no supplementary clinical or complementary investigations. The geriatrician in charge will have to systematically collect the indication and the history of the AD treatment. At the end of the evaluation performed in the geriatric day unit, the geriatrician will have to conclude to the AD overuse or not associated with off label prescription. Doubtful case will be examined by a validation committee. Eligibility criteria: Patient consulting in geriatric day hospital with age ≥70 years and dementia according to DSMIV criteria, whatever its level and antidepressant prescription. Sample size Considering that 40% of people suffering from ADAD are prescribed antidepressant (data from French Health Insurance), the number of eligible patients consulting in the geriatric day swill be 65 in 6 months. If 10% of them are opposed to the collection of their personal data and if the overuse of AD is near 50%, precision of the result will be 12.8% (95%CI bilateral). Duration of inclusion: 6 months Duration of patient's participation: one day

The investigators explore the presence of AD factors beta-amyloid and tau in CSF and plasma to verify AD diagnosis in patients with acute hip fracture. Clinical dementia test is performed prior to operation. Blood samples and CSF samples are collected at surgery and blood samples are collected postoperatively at intervals. Mortality is assessed at 30 days, 3 months and 1 year. Morbidity is assessed at , 3 months and >1 year. Neuromarkers specifically addressing the inflammatory component are to be analyzed and correlated to outcome together with AD markers, as above.

The current study is intended to enrich and extend the database of Alzheimer's Disease (AD) and healthy control (HC) MEG scans and will include patients meeting DSM-IV-TR criteria for dementia of Alzheimer's type, and age- and gender-matched HC subjects meeting criteria of normal neurological function. This study will include 2 MEG and electroencephalography (EEG) scans on approximately 80 AD subjects and 80 HC subjects over approximately 30 days. All subjects will have MEG/EEG scans at baseline and 28 - 35 days after baseline. Within one day of each scan visit AD subjects will undergo 4 standard functional tests while HC subjects will undergo 2 standard functional tests. This study will test the following hypotheses: MEG scans of resting-state, eyes-open brain function reveal patterns of correlated activity that differ between HC subjects and subjects diagnosed with dementia of Alzheimer's type; Patterns of correlated activity measured in AD subjects correspond to other measures of disease severity such as standard functional test scores; MEG scan patterns for HC subjects are consistent across repeated measures taken over a 30 day period.

The purpose of this study is to investigate prospective merory (memory of intentions) in healthy controls and in aMCI (amnestic Mild Cognitive Impairment) and AD (Alzheimer Disease) patients.
