Cognitive behavioral therapy, singly and combined with medication, for persistent insomnia: a randomized controlled...

Area of Science:

• Sleep Medicine
• Behavioral Therapy
• Pharmacology

Background:

• Cognitive behavioral therapy (CBT) and hypnotic medications are effective for short-term insomnia treatment, but complete remission is rare.
• The optimal approach for combined or maintenance therapies for insomnia remains unclear.

Purpose of the Study:

• To assess the benefits of adding medication to CBT for acute insomnia treatment.
• To determine the long-term effects of maintenance therapies on insomnia outcomes.

Main Methods:

• A prospective, randomized controlled trial involving 160 adults with persistent insomnia.
• Two-stage therapy: initial 6-week treatment (CBT alone vs. CBT plus zolpidem) followed by 6-month extended therapy.
• Outcomes included sleep parameters (latency, wake time, total sleep, efficiency) and treatment response/remission rates.

Main Results:

• Both CBT alone and CBT plus zolpidem significantly improved insomnia during acute treatment.
• Combined therapy showed a higher remission rate than CBT alone during the 6-month extended therapy and follow-up.
• Discontinuing zolpidem during maintenance CBT led to the best long-term remission rates.

Conclusions:

• Adding zolpidem to CBT offers acute benefits for persistent insomnia.
• Long-term insomnia outcomes are optimized by discontinuing medication during maintenance CBT, favoring CBT alone.
