Summary

This study looks at how a cardiac arrest affects brain function, including memory, thinking, and emotions. Researchers will follow 48 survivors for one year, using cognitive tests and brain scans (fMRI) to track changes. Their results will be compared to a healthy control group to understand the long-term impact.
