Summary

This study looks at why people with damage to the hypothalamus or pituitary gland often have sleep problems. Researchers will compare 60 patients to healthy volunteers using sleep tests, hormone measurements, and brain scans. The goal is to find better ways to prevent and treat these sleep issues.
