Transcranial Magnetic Stimulation in the Treatment of Addiction (MAGENTA)
Repetitive Transcranial Magnetic Stimulation (rTMS) in Alcohol Dependent Patients: a Mechanistic Study.
The investigators hypothesize that repetitive transcranial magnetic stimulation (rTMS) on the right side of the head will make craving towards alcohol less severe in recently detoxified alcohol addicted patients.
Although there are successful treatment option to detoxify patients form their alcohol use, many patients tend to relapse. This relapse is mainly caused by a high level of (uncontrollable) craving towards alcohol. This aspect of addiction is with the existing options hard to treat, there is a great need of new successful treatment modalities. rTMS is a FDA approved treatment method for depression. Recently some small scale studies have shown promising results on rTMS in the treatment of addiction. In this study the investigators focus on alcohol addiction since it is the addiction with the highest morbidity and mortality in the Netherlands.

Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Genders Eligible for Study
Description
Inclusion Criteria:
- Right-handed males between 23-65 years of age
- A primary diagnose of alcohol dependence (meeting the DSM-IV-TR criteria 303.90/ICD-10 F10.2)
- Written consent for participation of the study.
Exclusion Criteria:
- MATE outcome <4 (as extracted from part 4 MATE at enrollment phase)MATE= Dutch screening instrument on (among others) addiction severity
- Presence of a current or past relevant somatic or neurological disorder
- Meeting the DSM-IV-TR criteria for a current bipolar disorder, schizophrenia, anxiety disorder or moderate to severe depressive disorder. These disorders would be a possible great confounder. Measured with the MINI-plus.
- Meeting the DSM-IV-TR criteria for current (in the past 2 weeks) dependence of substances other than alcohol, nicotine or caffeine. Information present in MATE.
- Participant-bound factors that may endanger participants or may jeopardize study adherence, because of failure to understand and/or comply with instructions (e.g. current, disruptive symptoms such as psychotic symptoms or severe cognitive impairment)
Contra-indications resulting from the use of rTMS:
- Epilepsy, convulsion or seizure
- Serious head trauma or brain surgery
- Large or ferromagnetic metal parts in the head (except for a dental wire)
- Implanted cardiac pacemaker or neurostimulator

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Verum rTMS
n=15. After detoxification of alcohol (maximum 4 days) rTMS treatment will start : 20 sessions (5 times during 4 weeks)of verum rTMS on the right dorsolateral prefrontal cortex. Measurements of all objectives at baseline and 2,4,8 and 12 weeks after start treatment. |
rTMS on the right dorsolateral prefrontal cortex.
TMS procedure: The resting motor threshold (RMT) will be defined in each subject as the minimal stimulation intensity evoking an MEP of ≥ 0.05 mV in 50% of the trials in the muscle of the right thumb (M.
abductor pollicis brevis).
TMS will be conducted in the form of 'conventional rTMS', whereby 30 trains of 10 Hz pulses with a duration of 5 seconds and an inter-train interval of 25 seconds are applied to the righ dorsolateral prefrontal cortex (50 pulses per train, 6000 pulses per session).
Used equipment: Magstim Rapid 2 device.
|
Sham Comparator: Sham TMS
n=15. After detoxification of alcohol (maximum 4 days) rTMS treatment will start : 20 sessions (5 times during 4 weeks)of sham rTMS on the right dorsolateral prefrontal cortex. Measurements of all objectives at basleine and 2,4,8 and 12 weeks after start treatment. |
TMS procedure: The resting motor threshold (RMT) will be defined in each subject as the minimal stimulation intensity evoking an MEP of ≥ 0.05 mV in 50% of the trials in the muscle of the right thumb (M.
abductor pollicis brevis).
Like in verum TMS coil will be placed on the skull, but no magnetic field will be pulsed.
Used equipment: Magstim Rapid 2 device.
