Scientists probe gene link to anorexia, depression, and sleep problems
NCT ID NCT06800898
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at young women with anorexia nervosa to see if changes in a gene related to appetite and wakefulness (the orexin gene) are linked to how severe their eating disorder is, whether they have depression, and how well they sleep. Researchers will compare these women to a healthy control group. The goal is to better understand the biology behind anorexia, not to test a new treatment.
