While it is associated with significant distress, the current conventional antidepressants have shown only modest efficacy and exposed to potentially severe side effects.\n\nRecent evidence suggests that nitrous oxide (N2O) in its most commonly used packaging of EMONO (Equimolar Mixture of Oxygen and Nitrous Oxide) has rapid antidepressant properties and a good safety profile. However, no study has investigating the antidepressant effect of EMONO in a population of depressed older adults with moderate to severe neurocognitive disorders in nursing homes.\n\nThe principal goal of the PROTO-EHPAD study is to compare the changes in depressive symptoms in such individuals in a randomized controlled trial with a follow up period of 8 weeks, with a dosage escalation procedure.",[54,55],"Depression","Neurocognitive Disorders",[57],"Nitrous Oxide","NOT_YET_RECRUITING","2026-06-16",{"date":61,"type":62},"2026-06-17","ACTUAL",{"date":64,"type":48},"2026-09",{"date":66,"type":48},"2028-09",{"name":5,"class":6}]
