Background: This research aims explored the sleep disorder (SD) role in major depressive disorder (MDD), and the SD influencing their cognition.
Methods: 372 MDD patients and 457 healthy controls (HCs) were enrolled.
Results: Patients increased a 38.88 times SD risk compared with HCs. In patients, visuospatial/constructional score was lower in SD than non-SD, and PSQI score was negatively associated with visuospatial/constructional score of SD. In SD and non-SD, RBANS scores were lower in MDD than HCs, excepted for visuospatial/constructional in non-SD.
Conclusion: The SD as a MDD risk factor, has more serious visuospatial/constructional impairment alleviated via improving sleep/depression in patients.
