Filter by:The purpose of this Phase 1/Phase 2 study is to evaluate how the body handles the drug and the drug's effect on the body of participants with mild cognitive impairment (MCI) due to Alzheimer's Disease (AD) or mild AD and who test positive for amyloid plaque.
The purpose of this study is to evaluate the changes in the cognitive, functional, behavioral and global domains based on the different applicable psychometric batteries and scales.
This is an open label study of isotretinoin, a medication which is FDA approved for treatment of other conditions to determine initial safety in Alzheimer's disease.
The purpose of this clinical study is to investigate the safety and efficacy of deep brain stimulation (DBS)as a treatment option for patients with cognitive, behavioral, and functional disability of Alzheimer's disease.
A few studies suggest that patients suffering from neurodegenerative diseases (such a multiple sclerosis or Alzheimer's disease (AD)) show decreased thickness of the retinal nerve fiber layer (RNFL), indicating axonal degeneration. High-definition spectral domain optical coherence tomography (SD-OCT), performed without radiation in a few seconds per eye, offers a precise and standardized estimation of this parameter, which could constitute a biomarker for cerebral axonal degeneration. These RNFL deficits might even be the earliest sign of AD, prior to damage of the hippocampal region that impacts memory. Besides, some associations of AD with some degenerative diseases of the eye (glaucoma, microvascular abnormalities, age-related macular degeneration (AMD)) have also been reported. It therefore seems interesting to determine whether RNFL thickness, and other ocular parameters, may give some indications for a better detection of AD and cognitive decline in the elderly.
The main purpose of this research project is to study how seizure-like activity affects the blood flow in the brain of patients with Alzheimer's disease (AD). Changes in blood flow can change memory and thinking ability, as happens in Alzheimer's disease. The investigators are using a study drug called Levetiracetam, which helps control seizure-like activity to see if it can help change the abnormal blood flow in the brain that is seen in some people with Alzheimer's disease.
According to estimations, Alzheimer's disease affects approximately 860,000 people aged of more than 65 years in France. This disease is characterized by disorders of cognitive functions, including memory, associated with structural and functional modifications of the brain. These changes are evolving within the pathology progression and can be evaluated with neuropsychological tests (to assess capabilities such as language, orientation, etc.) and also with brain imaging (e.g. MRI). Alzheimer's disease is still poorly understood, nevertheless currently available treatments can slow its development if the disease is diagnosed early enough. Thus, the objective is to identify markers for early diagnosis of Alzheimer's disease, to better describe the evolution of this disease. The three main objectives of this project are - to identify, compare and combine predictive markers of Alzheimer's disease - to make a significant contribution to the understanding of the pathophysiological mechanisms of Alzheimer's disease - to study the ability of different neuroimaging techniques to follow the evolution of this pathology.
Regular physical activity is now recognized as a key element of good physical and mental health and this all ages. MAIN GOAL : Evaluate the effectiveness of physical training associated with a cognitive training in improving the cognitive function of patients diagnosed with Mild Cognitive Impairment (MCI). DESIGN : Controlled randomized monocentric and prospective study with clinical benefit for the patient with three groups : one physical training and cognitive exercise group, one physical training without cognitive exercise group and one control group. In agreement with the literature on the effects of physiological stress on cognitive performance, the investigators expect the best cognitive test scores in groups with exercise training compared with controls (35% versus 80% error), and better scores on the MMSE, IALD, depression Scale, Index of Pittsburg sleep quality and quality of Life Questionnaire. Furthermore the investigators hypothesize that this positive effect is greater in the physical training and cognitive exercise group compared with the physical training group only.
This is an efficacy and safety study evaluating a new treatment for subjects with mild to moderate Alzheimer's disease.
The purpose of the study is to examine the safety, tolerability, immunogenicity and pharmacokinetics of TTP4000 in subjects with Alzheimer's disease with mild cognitive impairment.
