About this trial

Alcohol activates reward systems in different brain areas, i.e., the nucleus accumbens, dorsal striatum, extended amygdala, and prefrontal cortex. These areas are all part of the reward neurocircuitry, which plays an important role in the development of addiction.

A former study performed on rodents has shown that a specific area of the forebrain, the septal nuclei, is associated with the feeling of reward and, hence, addiction when stimulated. However, whether the septal area is involved in reward and addiction in humans is sparsely investigated.

The purpose of this brain-imaging study is to assess how the septal nuclei react to alcohol-related pictures shown to participants diagnosed with alcohol use disorder while lying in an MRI scanner, compared to people without a diagnosis of alcohol use disorder. This might give us a better understanding of how the septal nuclei is involved in reward and addiction.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Diagnosed with alcohol use disorder (AUD) according to DSM-5, and alcohol dependence according to ICD-10

An Alcohol Use Disorder Identification Test (AUDIT) score ≥ 15

At least six heavy drinking days for the last 30 days, measured with the Time Line Follow Back (TLFB) method

Disqualifiers

Diagnosis of schizophrenia spectrum disorder, paranoid psychosis, bipolar disorder, or mental retardation

Previous or current substance use disorder other than AUD and nicotine use disorder

History of alcohol withdrawal seizures within the past 5 years

Alcohol withdrawal symptoms defined as a CIWA-Ar score > 9 at screening or at the fMRI session

Trial outcomes

Primary outcomes

1

Significant differences in alcohol cue related fMRI BOLD signals in the septal nuclei of the brain between AUD patients and healthy controls.

Data is obtained using the ALCUE fMRI paradigm with the septal area as a predefined region of interest (ROI).

Time frame
12 minutes while the brain scan is being conducted

Secondary outcomes

1

Significant differences between AUD patients and healthy controls with respect to the subjectively reported craving degree

The craving degree will be measured during the fMRI paradigm on a visual analogue scale ranging from 0 (no craving) to 100 (extremely extensive craving)

Time frame
From beginning of the fMRI scan to the end of it at 12 minutes
2

Significant differences between AUD patients and healthy controls with respect to alcohol cue related signals

The differences will be measured during the fMRI scan and analysed with BOLD-respons in putamen, caudate, nucleus accumbens and dorsal- and ventral striatum.

Time frame
From beginning of the fMRI scan to the end of it at 12 minutes
3

Correlation between subjectively reported craving and BOLD signals

A comparision between the subjectively measured craving degree using a visual analogue scale and the BOLD signals of the putamen, caudate, nucleus accumbens and dorsal- and ventral striatum measured during the fMRI

Time frame
From beginning of the fMRI scan to the end of it at 12 minutes
