Neurocognitive Decline

The goal of this clinical trial is to learn if an integrated protocol using multifocal non invasive brain stimulation and brain recording combined with cognitive training is effective in treating cognitive and affective symptomatology in patients with mild cognitive impairment and early stages of dementia. The main questions it aims to answer are: * Does multifocal non-invasive brain stimulation reduce cognitive and affective symptoms in patients with mild cognitive impairment and early stages of dementia? * Do some specific factors, such as education and cognitive reserve, affect the extent of the possible outcomes achievable from the intervention? * Do electrophysiological measures contribute identifying responders and non-responders to the treatment? Researchers will compare real non-invasive brain stimulation to a placebo stimulation (reproducing the same feeling of stimulation without actually stimulating the brain) combined with cognitive rehabilitation on general cognition measures and depression symptoms. Participants will * Undergo two treatment cycles (real stimulation or placebo over frontal and temporal ares of the left hemisphere) combined with cognitive training twice a week for two months. * Complete neuropsychological evaluations before the first rehabilitation cycle and at the end of each rehabilitation cycle. Caregivers will provide information on functional daily living activities for their relatives.

The MISTIC study is a non-profit, cross-sectional clinical research project aimed at investigating the relationship between atherosclerosis and both cardiovascular and cognitive function in adult populations. Atherosclerosis is a progressive condition characterized by the accumulation of material within arterial walls, leading to vascular narrowing and impaired blood flow. While its most recognized consequences are acute events such as myocardial infarction or stroke, earlier stages of the disease, often asymptomatic, may already be associated with functional changes affecting multiple organ systems. This study focuses on evaluating the association between vascular health and cognitive performance at a single time point. Atherosclerotic burden will be assessed using non-invasive imaging techniques, including carotid intima-media thickness and coronary calcium scoring. Cognitive performance will be measured using standardized neuropsychological tests. Approximately 1000 participants will be enrolled and divided into two groups: a control group without clinically established cardiovascular disease, and a group of patients with coronary artery disease (CAD). All participants will undergo clinical evaluation, vascular imaging, cognitive testing, and analysis of biological samples. The primary objective is to determine whether increasing atherosclerotic burden is associated with measurable differences in cognitive and cardiovascular function. Secondary aims include identifying patterns that may help improve early detection and risk stratification of vascular disease. The results of this study are expected to contribute to a better understanding of atherosclerosis as a systemic condition and to support the development of preventive strategies targeting early stages of vascular disease.

The prevalence of major neurocognitive disorders (MNCDs), particularly Alzheimer's disease, among older adults is increasing. These individuals and their caregivers often face challenges due to inefficient and poorly coordinated care transitions, negatively impacting patients, caregivers, healthcare professionals, and the healthcare system itself. To address this, the Quebec Ministry of Health and Social Services has released Phase 3 of its Ministerial Guidance on Major Neurocognitive Disorders, aiming to enhance care coordination between primary healthcare professionals and those living with MNCDs and their caregivers. Quebec's healthcare system comprises various organizations providing care and services to individuals with MNCDs. Each organization faces unique challenges hindering improvement initiatives. However, common obstacles persist: inadequate communication systems for sharing vital information, lack of access to data for measuring care transition quality, and the absence of patient/caregiver satisfaction assessments to inform service enhancements. Additionally, organizations require support in managing change. This need for improvement, coupled with the aspiration for a patient-centered learning health system (LHS), motivated the Institut national d'excellence en santé et services sociaux (INESSS), the Centre intégré de santé et de services sociaux de Chaudière-Appalaches (CISSS CA), and the research team to collaborate on adapting a proven continuous improvement program: the CoMPAS+ MNCD Program. The Program will involve reflecting on best practices and identifying local challenges within participating Family Medicine Groups (FMGs) to propose and implement solutions. The CONSTELLATIONS Living Lab project has been tasked with co-developing, implementing, and evaluating the Program's impact on care transitions over two years. These findings will inform decision-makers and stakeholders about the Program's adaptability to the Chaudière-Appalaches region, guiding local and provincial decision-makers on healthcare system improvements and emphasizing the importance of supporting an LHS.
