Overview
Our primary objective is to integrate tVNS and mindfulness meditation within a structured mindfulness-based relapse prevention (MBRP) program for detoxified alcohol-dependent patients (AD). We aim to determine whether neuromodulation can enhance mindfulness-based relapse prevention compared to mindfulness practice alone. In this context, we will investigate potential changes in the interaction of top-down control and cue reactivity, as well as assess the severity of AUD. Measurements of drinking behavior, cravings, and abstinence rates will be conducted up to three months post-treatment. Our second objective is to examine the causal role of frontal midline theta oscillations (FMΘ) in MBRP and cognitive control. To achieve this, we will first establish closed-loop amplitude-modulated transcranial alternating current stimulation (CLAM-tACS) to selectively modulate FMΘ oscillations during MBRP meditation exercises in AUD patients (2).
