In this Expert Interview, I interview Dr. Barry Krakow about his work on PTSD (post-traumatic stress disorder), insomnia, and obstructive sleep apnea. These are the questions I asked:

- How did you get involved with mental health patients who have sleep disorders?

- How is insomnia and sleep apnea related to post-traumatic stress disorder (PTSD)?

- What’s the hard evidence that sleep-breathing disorders and insomnia go hand-in-hand?

- Why do you use the term, complex insomnia to describe the co-existance of insomnia and sleep apnea?

- Tell us about your paper that’s coming out in SLEEP on complex insomnia.

- What comes first, insomnia or sleep apnea?
