Treatment of Chronic Insomnia With Cognitive Behavioral Therapy vs Zopiclone

JAMA. 2006;296(20):2435-2436. doi:10.1001/jama.296.20.2435-a

To the Editor: In their study of treatment of chronic primary insomnia in older adults, Dr Sivertsen and colleagues1 found that cognitive behavioral therapy (CBT) resulted in improved short- and long-term outcomes compared with zopiclone on 3 out of 4 outcome measures.

However, they did not have data specifically addressing daytime sleepiness as an outcome measure, which they note would have been interesting to compare with the observed changes in slow-wave sleep. The absence of this information limits the implications of this study; I believe that research in this area should concentrate more on daytime functioning as an outcome measure of this widespread disorder.
