BREMISS : Brain Resilience Minor Stroke Study

The objective of this clinical trial is to develop, based on patients' initial characteristics (in the first few weeks following the stroke), a predictive model of quality of life more than 4 years after the stroke in patients who have suffered a minor ischemic stroke. The main question it aims to answer is: \- Is it possible to predict the quality of life of patients who have suffered a minor ischemic stroke based on their initial characteristics? To do this, retrospective and prospective data collected as part of the study will be analyzed using a conventional statistical approach and algorithms based on AI approaches in order to create a predictive model. Participants will be asked to: * Complete questionnaires * Provide a saliva sample (optional) * Undergo an MRI scan (optional)
