Clinical Trial Summary

In this feasibility study the investigators are using a setup of stress-related body sensors including established as well as innovative sensor-based measures to identify predictor profiles for alcohol-related behavioral and neural measures in Alcohol Use Disorder (AUD). Long-term aim is the definition of a setup of mobile sensors and their integration in a mobile infrastructure that allows the prediction of stress related alcohol intake in an ambulatory setting.

Description:

The long-term aim is the definition of a setup of mobile sensors and their integration in a mobile infrastructure that allows the prediction of stress related alcohol intake in an ambulatory setting.

In patients with Alcohol Use Disorder (AUD) stress exposure is known to affect craving, cue-reactivity and relapse risk. Here, the investigators aim to identify stress- and alcohol cue-related physiological markers in a lab experiment to assess interactions between acute psychological stress exposure and alcohol cue-exposure regarding their effects on alcohol craving and related markers (attentional bias to alcohol-cues, implicit association task, neural cue-reactivity). In addition to applying established stress-related markers (cortisol in saliva, heart-rate variability, systolic blood pressure and electrodermal activity), the investigators will integrate innovative measures currently under investigation (e.g. voice stress analysis) to identify whether these additional parameters increase the predictive significance.

Primary	change in heart rate variability	heart rate variability acquired with ear clip (continuous time series)	at examination day: continuous measurement throughout the whole experiment (except during MRI scanning); duration around 2 hours; starting 1 hour 50 minutes after arrival of the proband
Primary	change in blood pressure (systolic and diastolic)	acquired with pressure sleeve	at examination day: 6 time points measured throughout the whole experiment (except during MRI scanning); at 2:20h, 2:50h, 3:20h, 3:50h, 4:50h, 5:05h after arrival of the proband
Primary	change in electrodermal activity	time series acquired with body sensor	at examination day: continuous measurement throughout the whole experiment (except during MRI scanning); duration around 2 hour; starting 1h 50min after arrival of the proband
Primary	neural alcohol-related cue-reactivity	% signal change, measured with fMRI; paradigm Vollstädt-Klein et al. 2010 [% signal change is not a change over time; it is measured during one experimental session]	at examination day: measured directly after the behavioral tasks at the end of the lab experiment
Primary	neural inhibition processing	% signal change, measured with fMRI; stop-signal reaction time task (Fauth-Buhler et al. 2012) [% signal change is not a change over time; it is measured during one experimental session]	at examination day: measured directly after the behavioral tasks at the end of the lab experiment
