Summary
This study looked at how two prostate cancer drugs, darolutamide and enzalutamide, affect thinking and memory in men with advanced prostate cancer. About 111 men took one of the two drugs and completed computer-based cognitive tests over time. The goal was to see if one drug causes fewer mental side effects than the other.
