Filter by:This study hopes to investigate differences in lymphatic health of patients with Alzheimer's disease by analyzing diffusion-weight images in conscious and sleep states. Dexmedetomidine is a short-acting agent that facilitates a sedated state characterized by slow waves and inhibition of norepinephrine. Conceptually, dexmedetomidine may be preferred to other agents, because it is a short-acting norepinephrine blocker, which could mimic slow wave sleep architecture, opening interstitial spaces, and facilitating plaque removal. Dexmedetomidine may also be preferred given its safety profile among the elderly and acutely ill compared to other anesthetic agents. Sleep will be induced with dexmedetomidine, and interstitial fluid convection will be assessed by measuring free-water diffusion imaging. Freewater diffusion imaging separates out the contributions of extracellular free water and water in the vicinity of cellular tissue; it is used to evaluate abnormalities in extracellular space, such as neuroinflammation, which may contribute to long-term cellular degeneration. This method of analysis could be useful in assessing the lymph systems ability to remove extracellular debris.
This is Phase 3 study, multi-centre, double-blind, placebo controlled, parallel group to evaluate the effects of AC-SD-03 on the efficacy and safety among participants with mild to moderate Alzheimer's Disease.
The aim of our study is the analysis of sleep phases and quality as well as the detection of respiratory pauses in subjects with cognitive disorder. To assess whether sleep quality is associated with the blood-brain barrier and Alzheimer's disease, which may be indicative of an early, non-invasively measurable change in brain activity in the early stages of Alzheimer's disease.
The present studies demonstrated that pro-inflammation, systemic oxidative stress and dysfunction in the brain-gut microbiota axis were involved in Alzheimer's disease (AD) pathogenesis. These results implied the decreased regulation of inflammation-associated risk and microbiota in AD patients could provide the novel strategies for combating the disease. This study was designed to assess the addition of Wismemo in treatment of cholinesterase inhibitors (such as donepezil, rivastigmine, galantamine) in the AD patients.
Evaluate cognitive improvement pre amd post acupuncture treatment in patients with probable alzheimer's dementia as measured by MOCA score and also per form A( measure of patient's personal information). Also caregiver input.
The general purpose of this observational study is to examine biomarkers associated with the pathology of neurodegenerative diseases to potentially develop novel therapeutic approaches.
The object of this study is to investigate the use of linguistic deficits from speech samples for the early detection of Mild Cognitive Impairment and probable Alzheimer's disease. It will also evaluate whether the result of the Amyloid PET scan would confirm the effectiveness of a less expensive and less intrusive diagnostic technique through speech
According to 2011 HAS recommendations, early detection of Alzheimer disease is the major objective in order to allow an earlier care and support. These recommendations strengthen general practitioner role, who plays a key role in the identification of cognitively impaired patients. HAS recommendations are the use of MMSE like test (Mini Mental State Examination) at general practitioner office. A self-screening test, without medical presence, would allow a self-administered cognitive assessment by the patient. A review of the literature about self-administered cognitive tests has been realized. The Self-Administered Gerocognitive Examination (SAGE) has been chosen. It is a brief, valid and reliable cognitive assessment tool, rated on 22 points, which allows an early detection of cognitive impairment, with a sensitivity close to the MMSE test. Nevertheless, SAGE has never been tested at home without medical supervision. In this study, the investigators will determine if SAGE scores at home correlates with MMSE scores at general practitioner office. Patients with inclusion criteria will be recruited during the general practitioner consultation and will have a clinical assessment included MMSE and clinical data collection. Then, SAGE will be given to the patient in order to be completed at home without medical supervision and send to the general practitioner.
The current study is being conducted by the Sponsor to evaluate the efficacy and safety of GV1001 (0.56 mg and 1.12 mg) administered subcutaneously as a treatment for moderate Alzheimer's disease (AD). GV1001 has been shown to inhibit neurotoxicity, apoptosis, and the production of reactive oxygen species induced by amyloid beta in neural stem cells by mimicking the extra-telomeric functions of human telomerase reverse transcriptase (hTERT). In nonclinical studies, using both mild (early stage) and severe (late stage) AD mouse models, GV1001 has been shown to improve cognitive function and memory, as well as significantly reduce the amount of amyloid beta and tau proteins. The multifunctional effect of GV1001 makes it a promising therapeutic option for the treatment for AD.
The primary objective of this study is to identify a new radioligand for imaging of tauopathy in Alzheimer's disease through direct comparisons of two potential candidates, [18F]RO-948 (formerly known as [18F]6958948) and [18F]MK-6240, and demonstration of the candidates' absence of off-target binding.
