Summary

This study examines whether memory problems after a type of brain bleed (aneurysmal subarachnoid hemorrhage) are linked to a smaller hippocampus, a brain area key for memory. Researchers will compare 30 patients in rehabilitation with healthy volunteers using memory tests and MRI scans. The goal is to understand why some people have lasting cognitive issues even without obvious brain damage.
