StrokeCog-BBB to Study Cognitive Outcomes Following Stroke


Trial ID: NCT06116630


The goal of this observational study is to learn about cognitive outcomes in stroke patients. The main question it aims to answer are: 1. Is blood-brain barrier permeability compromised for years after stroke, 2. Is a blood biomarker of imbalanced angiogenesis dysregulated in chronic stroke and 3. Are there biomarkers that separately or together predicts cognitive decline after stroke, and are other MRI, blood, and clinical characteristics that are associated. Participants will undergo cognitive testing and MRIs two years apart. Researchers will compare cognitive outcomes in non-stroke patients who have cardiovascular risk factors to understand the effects of stroke on these outcomes.
