Summary
This study looks at how social and lifestyle factors—like education, race, and income—affect a person's thinking and memory after a stroke. Researchers will interview 450 adults who had a stroke and review their brain scans and medical records. The goal is to understand why some people maintain mental function while others develop dementia.
