Filter by:The aim of this study is to understand regional variations in acetylcholine esterase activity in Alzheimer's disease. In this study the aim is to identify by PET the physiological values of the regional activity of acetylcholine esterase using the 11C PM4 tracer and to study by PET and 11C PM4 the brain activity of acetylcholine esterase in a group of patients with Alzheimer's disease, enrolled according to the inclusion and exclusion criteria. The PET data will be correlated with the clinical, neuropsychological and morphological data acquired by MRI and with the clinical-cognitive outcome.
Preclinical and clinical data have demonstrated the ability of the 11C-PIB tracer to selectively bind accumulations of amyloid protein, a neuropathological marker characteristic of the neurodegenerative pathologies covered by this study. The validation in larger groups of patients, and the comparison between the different clinical syndromes included in the spectrum, will allow the diagnostic and prognostic potential of the tracer to be evaluated, with important consequences for the clinical management of patients. In particular, the tracer could play a central role in the clinical management of patients with neurodegenerative diseases and cognitive impairment. Numerous pharmacological trials are currently underway, worldwide, for the validation of anti-amyloid drugs. In the future we could think about early monitoring with imaging of the effectiveness of the treatment. T he FDG PET technique can be of great help in obtaining relationships between radiation damage to the brain and possibly neurological and neuropsychological deficits associates.
This study focuses on assessing and measuring white matter hyperintensities in individuals with amnestic mild cognitive impairment (aMCI) or Alzheimer's disease. Objective: The primary objective of the study is to quantify the extent and distribution of white matter hyperintensities in the brains of individuals diagnosed with amnestic mild cognitive impairment or Alzheimer's disease. White matter hyperintensities are areas of increased signal intensity observed on brain magnetic resonance imaging (MRI) scans, often associated with various cognitive disorders. Importance: Understanding the presence and severity of white matter hyperintensities in individuals with aMCI or Alzheimer's disease is crucial for several reasons. These abnormalities may serve as potential biomarkers, aiding in the early diagnosis and prognosis of cognitive disorders. Additionally, quantifying white matter hyperintensities could contribute to a better comprehension of the underlying neuropathological processes associated with these conditions. Methods: The study employs advanced imaging techniques, likely including MRI, to capture and analyze white matter hyperintensities in the brains of participants with amnestic mild cognitive impairment or Alzheimer's disease. The quantification process involves precise measurement and mapping of these hyperintense regions. Participants: The study involves individuals diagnosed with amnestic mild cognitive impairment or Alzheimer's disease. Participants will undergo neurological assessments and imaging procedures to facilitate the accurate measurement of white matter hyperintensities. Expected outcomes: Researchers anticipate that the quantification of white matter hyperintensities will provide valuable insights into the progression of cognitive disorders. The results may contribute to the development of more targeted and effective diagnostic and therapeutic interventions for individuals with amnestic mild cognitive impairment or Alzheimer's disease. Conclusion: This study represents a significant step toward enhancing our understanding of the neuropathological changes associated with amnestic mild cognitive impairment and Alzheimer's disease. By focusing on the quantification of white matter hyperintensities, researchers aim to uncover potential markers for early detection and monitoring of these cognitive disorders.
This is a randomized, double-blind, placebo-controlled, parallel group study. The use of placebo is appropriate to minimize bias related to treatment expectations of the subject, study partner, and site investigator, as well as to changes in the relationship between the subject and study partner that might occur with the initiation of treatment and expectation of improvement in motor symptoms or cognition. Changes in subject/study partner interactions can impact subject mood and might introduce biases that cannot be quantified. The double-blind use of placebo will also prevent bias in the clinical and scientific assessments.
Early Age-Related Hearing Loss Investigation (EARHLI) is a single site study that will randomize late middle age adults to either a hearing intervention (including hearing aids) or a health education intervention. Participants will be followed for 1 year. This study will provide information on reducing cognitive decline in those at risk for Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD).
The purpose of this study is to address the unmet care needs and reduce the care burdens for persons with ADRD (Alzheimer's Disease and Alzheimer's Disease Related Dementias) and their caregivers by providing monitoring of daily activities and gestures using audio and radio sensing, providing voice-based reminders intervention. In phase 1, dyads will participate in two focus groups will take 60 minutes per each. In Phase 2, AURA_ALZ (connecting Audio and Radio Sensing Systems-Alzheimer's Disease) will deployed for two weeks at participants' home. At the end of the two weeks, usability, acceptability of the use of the system will be measured.
The Alzheimer's Network for Treatment and Diagnostics (ALZ-NET) will collect longitudinal clinical and safety data for enrolled patients being evaluated for or treated with novel FDA-approved Alzheimer's disease (AD) therapies. ALZ-NET is a longitudinal registry with an expandable platform, designed to grow with scientific and medical advancements. As new treatments are approved and implemented in care, ALZ-NET will track the long-term health outcomes associated with their use in a real-world setting. ALZ-NET is a resource for evidence gathering, information sharing and education across clinical and research communities, encouraging innovative research and supporting opportunities to improve clinical care delivery. All participating physicians and site staff will complete comprehensive training to ensure adherence of data requirements and registry timelines.
Oral supplementation of histidine in patients with cognitive dysfunction should increase brain anserine, carnosine and histamine levels which will result in improved cognition via numerous proven in vivo mechanisms including increasing blood flow, neurogenesis, angiogenesis, activation of histaminergic neural pathways and autophagy of beta-amyloid protein, which is pathognomonic for Alzheimer's disease. Randomized into one of 2 arms to receive Histidine or placebo to take for up to 3 months. Baseline evaluation and followup evaluation at 3 months postop.
Alzheimer's disease (AD) is the leading cause of dementia in France. It is a multifactorial pathology, combining genetic and environmental risk factors. Homocysteine, a sulfur-containing amino acid belonging to the methionine-monocarbon cycle, has frequently been found at high levels in neurodegenerative diseases, and in AD in particular. It has been shown on human brain sections that the interaction of homocysteine with tau and MAP1, two key AD proteins, was significantly higher in AD patients than in controls, and corresponded to an N-homocysteinylation type interaction. This is a prospective study, the main objective of which is to compare MAP1 N-homocysteinylation levels in fibroblasts from individuals with AD versus disease-free cell lines.
This study will evaluate the Pain Identification and Communication Toolkit (PICT), a multicomponent intervention for caregivers of people with Alzheimer's disease and related dementias (ADRD). PICT provides training in observational pain assessment and coaching in effective pain communication techniques. It will recruit participants from programs of all-inclusive care for the elderly (PACE). The investigators hypothesize that PICT will help caregivers to recognize and communicate about pain in their care recipients.
