Insomnia may spur anxiety disorders
That's according to a Norwegian study published in the journal Sleep.
The study defines chronic insomnia as the subjective feeling of having trouble falling or staying asleep most nights for at least a month.
People with chronic insomnia should be screened to see if they have an anxiety disorder or depression, note the researchers. They included Dag Neckelmann, MD, PhD, of the psychiatry department at Haukeland University in Bergen, Norway. view article
