Neurofeedback for alcohol addiction: Changes in resting state network activity^✰

Area of Science:

• Neuroscience
• Addiction Research
• Medical Imaging

Background:

• Alcohol dependence remains a significant global health issue.
• Existing treatments for alcohol dependence have limitations.
• Neuroimaging techniques offer insights into addiction mechanisms.

Purpose of the Study:

• To investigate neurofeedback training's effect on resting-state fMRI activity in alcohol-dependent patients.
• To identify brain regions crucial in addiction disorders affected by neurofeedback.
• To explore neurofeedback as a potential therapeutic tool for alcohol dependence.

Main Methods:

• 52 patients with alcohol dependence were recruited and randomized into active and sham neurofeedback groups.
• The active group received three sessions of neurofeedback training.
• Resting-state fMRI data were collected and analyzed across six measurement days.

Main Results:

• A significant reduction in activated voxels within the ventral attention network was observed after neurofeedback training.
• Overall, a decrease in activated voxels across analyzed networks was noted compared to baseline.
• These changes suggest neurofeedback may decrease reliance on external stimuli.

Conclusions:

• Neurofeedback training shows potential in altering brain activity associated with alcohol dependence.
• Reduced activity in specific networks may enhance cognitive control and reduce craving.
• Resting-state fMRI activity changes could serve as biomarkers for treatment efficacy in alcohol use disorder.
