Multimodal Retinal Imaging in the Detection and Follow-up of Alzheimer's Disease
Because of a shared ontogenic origin, the retina displays similarities to the brain and spinal cord in terms of anatomy, functionality, response to insult, and immunology. Hence, the retina can be approached as an integral part of the central nervous system. The occurence of ocular manifestations in several neurodegenerative pathologies, …
Memory and Social Interactions
Memory and social interaction are intimately linked. On the one hand, social interaction is a privileged context for learning, and on the other hand, appropriate social interactions involve remembering the partners encountered and previous exchanges. People with Alzheimer's disease classic syndrome variant (AD) have a major impairment of episodic memory, …
Tanycytes in Alzheimer's Disease and Frontotemporal Dementia
Metabolic and hormonal deregulations are both a risk factor and a hallmark of Alzheimer's disease (AD) and frontotemporal dementia (FTD), occurring early in the course of the disease. In FTD in particular, hyperorality and dietary changes are associated with metabolic and hormonal changes such as altered levels of the anorexigenic …
Environmental Pollutants and Neurological Disorders
Environmental pollutants have emerged as a major global health concern, with growing evidence linking exposure to both traditional contaminants such as heavy metals (lead, mercury, cadmium, arsenic) and novel pollutants-including micro- and nanoplastics, perand polyfluoroalkyl substances (PFAS), antibiotics, and endocrine-disrupting chemicals-to adverse neurological outcomes. These pollutants can cross or disrupt …
Autobiographical Specificity
Autobiographical memory is diminished in patients with Alzheimer's Disease and those with behavioral variant of frontotemporal dementia, and research has focused on the hampered ability of patients in retrieving specific memories. However, this study proposes a detailed methodology to provide a qualitative analysis of autobiographical specificity.
Ruijin Neurobank of Alzheimer's Disease and Dementia
The goal of this observational study is to learn about neuroimage and biomarkers in the Alzheimer's continuum. The main questions it aims to answer are: How is the neurovascular coupling during AD pathogenesis? How is the pattern/mapping of alterations in AD biomarkers? Participants will be observed and visit the research …
White Matter Hyperintensities in Amnestic Mild Cognitive Impairment or Alzheimer's Disease
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 …
OCT Angiography and NRAI in Dementia
The primary goals of this study are to use optical coherence tomography (OCT) angiography (blood vessel mapping) to: Detect retinal blood vessel and blood flow changes in participants with dementia. Detect amyloid protein deposits in the retinas of participants with dementia.
Effect of LEQEMBI on Cerebral and Retinal Amyloid in Mild Cognitive Impairment Due to Alzheimer's Disease
This is a proof of concept observational study is to determine if there is correlation between Aβ plaques and vascular findings in the Retina versus brain ARIA.
Screening for Anti-amyloid Treatment Eligibility Using Digital Cognition and Blood-based Biomarkers
This study evaluates a diagnostic screening solution for Alzheimer's disease (AD) using digital cognitive assessments and blood-based biomarkers. The aim is to reduce time-to-treatment for patients who may benefit from disease-modifying therapy (DMT). The study involves 500 patients referred to the MoCA Clinic in Montreal. Clinical stages will be assessed …
