Neuropsychological and Brain Medical Imaging Study in Patients With Brain Damage 2

This study uses neuropsychological testing and brain MRI scans to better understand how different types of brain damage — from strokes, tumors, developmental conditions, or other causes — affect thinking, memory, and other cognitive functions. By mapping how specific brain lesions relate to specific deficits, researchers aim to improve diagnosis and treatment planning. Both patients with documented brain damage and healthy volunteers are enrolled as comparison groups. Advanced brain imaging and cognitive tests are used to characterize these relationships. Participants must be French-speaking adults (18+), and patients must have a focal brain lesion or a developmental/degenerative condition with cognitive deficits. You may be eligible if you: - Are 18 years of age or older - Speak French - For patients: have a documented focal brain lesion (stroke, tumor, trauma, inflammation) or developmental/degenerative disease with cognitive deficits - For healthy volunteers: have no significant neurological or psychiatric history - Are able to provide informed consent You may NOT be eligible if you: - Have current severe depression or anxiety (patients) - Have significant visual or auditory impairment - Are taking psychotropic medications (other than low-dose hypnotics or anxiolytics) - Are currently pregnant or breastfeeding - Have a contraindication to MRI (e.g., metal implants, pacemaker) Talk to your doctor to see if this trial is right for you.
