RT Journal Article SR Electronic T1 Advances in treating insomnia JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 251 OP 266 VO 74 IS 4 A1 Budur, Kumar A1 Rodriguez, Carlos A1 Foldvary-Schaefer, Nancy YR 2007 UL http://www.ccjm.org/content/74/4/251.abstract AB Too often, insomnia is treated as a symptom without investigation of the cause. Insomnia may be a condition unto itself (primary insomnia), or it may be associated with a medical or psychiatric condition (comorbid insomnia), and it may be acute or chronic. Inadequate treatment often leads to significant frustration and lost productivity. We review the classification, pathophysiology, and treatment of insomnia and discuss how we can minimize its adverse consequences.
