REM Sleep Behavior Cohort Associated Depression With Poorer Response to Clonazepam or Melatonin
A record review found that depression marked a lower likelihood of symptom improvement. The combined treatment endpoint did not isolate clonazepam’s independent efficacy.

The cohort result
Among 123 patients, treatment involved clonazepam, melatonin, or both. Most reported improvement in dream-enactment behavior or unpleasant dreams during follow-up.
Depression was associated with a negative response after adjustment for selected factors. The confidence interval was wide, reflecting uncertainty around the estimate.
Depression and treatment can overlap
The authors could not determine whether depression itself or antidepressant exposure explained the association. Retrospective reporting, individualized titration, and mixed regimens also limited interpretation.
The study cannot establish that clonazepam fails in all depressed patients or that adding a medicine will restore response. Preserve diagnostic criteria, baseline symptoms, co-medication, follow-up, and the response definition. Group associations should not replace assessment of the actual nocturnal behaviors and treatment effects in an individual.
