Addressing cognitive deficits in alcohol use disorder (AUD) supports recovery. Impaired metacognitive functioning in AUD causes compromised recognition of the interoceptive state leading to the maintenance of alcohol abuse despite negative consequences. By promoting greater self-awareness and self-regulation, neurofeedback training is of high relevance in metacognition remediation to support abstinence.

The main objective of the present study is to validate neurofeedback as a complementary clinical tool to overcome metacognitive deficits that represent a significant factor in the maintenance of harmful consumption behavior and relapse phenomena in AUD.
