Alzheimer and Sleep
Alzheimer's DiseaseThe aim of the study is the analysis of two inhibitors of Ach-E: galantamine and donépézil in over 65 years' old patients suffering from Alzheimer disease (MMSE between 20 and 26) without Alzheimer's medication.
The Clinical Response of Choline Acetyltransferase and Apolipoprotein Epsilon Gene Polymorphisms...
Alzheimer's DiseaseThis study attempts to differentiate the clinical responses of Choline Acetyltransferase and Apolipoprotein Epsilon gene polymorphism to donepezil in Alzheimer's Disease patients.
Brain Characterization of Amyloid Protein and Glucose Metabolism of ALFA Project Participants
Alzheimer's DiseaseStudy to understand factors related with the preclinical stages of Alzheimer's Disease and investigate markers that predict its progression. Cross-sectional and single arm study performed on a subgroup of individuals recruited in the ALFA project. Study without therapeutic interest for the research participants (440 participants of the ALFA project who have been selected for being cognitively healthy and in their vast majority are direct descendants of patients diagnosed with Alzheimer's Disease). Each study candidate will be selected from the ALFA project (STUDY 45-65 FPM/2012) according to their clinical characteristics, their compliance to selection criteria and their desire to participate in this study. After signing this study's specific informed consent form, the neuropsychological screening and the brain MRI acquisition will be performed. Once all inclusion criteria are checked, the PET scans with 18F-Flutemetamol and 18F-FDG will be performed
TNF-Alpha Inhibition for Treatment of Alzheimer's Disease
Alzheimer's DiseaseIt is widely believed that inflammation contributes to the pathogenesis of AD. TNF has been implicated in both AD and neurological inflammation. Anti-TNF therapy is therefore surmised to be of potential benefit for treating AD.
Rivastigmine Monotherapy and Combination Therapy With Memantine in Patients With Moderately Severe...
Alzheimer's DiseaseThis is a prospective, multicenter, open-label study. Following screening and baseline assessments, eligible patients will be switched to rivastigmine and will enter the 16 week run-in rivastigmine treatment phase. After completion of assessments at the end of the run-in phase, patients who were not sufficiently stabilized on rivastigmine alone will receive add-on memantine to their rivastigmine treatment; patients who were stabilized on rivastigmine alone will have completed and be discontinued from the study.
A Multicenter Trial of Rofecoxib and Naproxen in Alzheimer's Disease (NSAID Study)
Alzheimer DiseaseThe primary specific aim of this clinical trial is to determine whether treatment with rofecoxib or naproxen for one year will slow the rate of decline of cognitive function in patients with Alzheimer's disease (AD) as measured by ADAScog.
Supporting Episodic Memory With Transcranial Direct Current Stimulation in Healthy Controls and...
HealthyMild Cognitive Impairment1 morePrevious studies showed that anodal tDCS applied over the dorsolateral prefrontal cortex (DLPFC) improved episodic memory performance, indicating a possible use as an intervention for patients suffering from memory impairments. At the same time, only scant evidence (provided by functional magnetic resonance imaging (fMRI) and magnetic resonance spectroscopy (MRS)) exists regarding the underlying mechanisms, thus hindering a more targeted application. The present study aims at establishing a connection between the stimulation-induced change in episodic memory performance on the behavioural level and neurophysiological parameters. TDCS effects and the underlying mechanisms will be compared between different study conditions, receiving either real anodal tDCS or sham stimulation over the left dorsolateral prefrontal cortex during an episodic memory task.
Memory for Action in Neurological Patients
Alzheimer DiseaseParkinson DiseaseMemory for action is especially important in everyday life although current literature is not very abundant. The enactment effect (i.e. better memory for performed actions than for verbally encoded sentences) is usually described as a robust effect in aging and can be found in many diseases. Although the enactment effect has been studied for three decades, there is still no consensus on how it enhances memory. Therefore, in order to gain additional insight into the representational basis of the enactment effect, in the present study, the investigators propose to test neurological patients. The investigators suggested that memory for action should be better than memory for verbally encoded information in Alzheimer's disease and Parkinson's disease. If patients with Alzheimer's disease (AD) and Parkinson's disease (PD) have no cognitive assessment during the last 6 months, then they will realize different tests: MMSE (1), HAD (2), a cognitive assessment (3); (4); BREF (5); Assessment of apraxia, (6). Controls will perform the same tests to verify that they have no cognitive impairment. Then, two experimental conditions will be presented in all patients and controls: a first in which participants will have to name drawings (verbal learning) and a second in which they will have to reproduce an action associated with drawings (action learning). Immediately after this learning phase, a recognition task will be available and therefore participants will have to recognize drawings that had been presented previously. The main criteria used in the statistical analysis will be the correct recognition score.
Study of Uptake, Break Down and Elimination of an Investigational Drug in Healthy Volunteers
Alzheimer's DiseaseThis study is being performed in order to learn more about a new drug (possible as treatment for people with Alzheimer's Disease and other conditions with cognitive dysfunction (memory and attention problems)) and how it is handled by the body by giving the drug to healthy volunteers with different genotypes.
Tricaprilin Liquid Formulation PK Study
Alzheimer DiseaseThe purpose of this study is to evaluate the pharmacokinetics, safety, and tolerability of new liquid formulations of tricaprilin, with the aim of finding a suitable formulation to advance in development. This is a three-part, part-randomised study that include single-dose, food effect, and titration tolerability in up to 80 healthy participants.
