Last week ABC news reported on a new study in the Journal of Clinical Sleep Medicine that examined the relationship between insomnia and suicidal thoughts.  AASM member W. Vaughn McCall, MD, explained to ABC that this relationship may be mediated by dysfunctional attitudes and beliefs about sleep as well as nightmares.  In a story by My Health News Daily that was featured on, McCall added that the focus of his current study is to explore how this understanding may provide a new target for treatment and suicide prevention.
