A Randomized Controlled Trial Comparing Neurofeedback and Cognitive-Behavioral Therapy for Insomnia Patients: Pilot...

Area of Science:

• Neuroscience
• Sleep Medicine

Background:

• Insomnia disorder is frequently associated with hyperarousal.
• Limited research has explored direct interventions targeting cortical arousal for insomnia.

Purpose of the Study:

• To compare the efficacy of a neurofeedback protocol for reducing cortical arousal against cognitive-behavioral treatment for insomnia (CBT-I).

Main Methods:

• Seventeen adults with insomnia were randomized to receive either neurofeedback or CBT-I.
• Participants completed validated questionnaires assessing insomnia severity (ISI), sleep quality (PSQI), and dysfunctional sleep beliefs (DBAS-16).
• Electroencephalogram (EEG) data was analyzed for changes in brainwave activity.

Main Results:

• Neurofeedback led to decreased beta waves and increased theta and alpha waves, indicating reduced cortical arousal.
• Both neurofeedback and CBT-I significantly improved Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI) scores.
• Neurofeedback did not significantly decrease Dysfunctional Beliefs and Attitudes about Sleep Scale (DBAS-16) scores, unlike CBT-I.

Conclusions:

• Neurofeedback training can alleviate insomnia symptoms by reducing cortical hyperarousal.
• Neurofeedback shows promise as a treatment for insomnia, though CBT-I may be more effective for addressing cognitive aspects of the disorder.
