Summary:

      Epidemiologic reports have linked insomnia to suicidal ideation and suicide death. However,
      no studies have determined whether treating insomnia decreases the risk of suicidality. We
      have new data indicating that (1) the link between insomnia and suicidal ideation holds true
      in clinical trials of depressed insomniacs, (2) dysfunctional cognitions about sleep are
      related to suicidal ideas, and (3) treatment of insomnia with hypnotics leads to a reduction
      of suicidal ideation. We now propose to test whether cautious use of hypnotics in suicidal,
      depressed insomniacs may reduce suicide risk in a multi-site clinical trial.
