Conditions
Summary
Alcohol Use Disorder (AUD) is a major public health problem that affects the physical, social, family, and mental integrity of the sufferer. Behavioral self-regulation is compromised in AUD, and a benefit has been reported with the application of repetitive transcranial magnetic stimulation and emotional self-regulation. The aim of this study is to investigate the efficacy of high-frequency rTMS to improve executive functions in patients in abstinence from AUD.
Eligibility
Inclusion Criteria9
- Men and women of 25 to 59 years old
- The reading level of at least 6th grade of primary (equivalent to fifth grade of elementary school).
- Alcohol users with and AUDIT ≥ 20 puntos
- Abstinence from alcohol consumption from 8 weeks to 5 years, with CIWA-Ar scale scores ≤ 9 points.
- No disabling neuropsychiatric conditions (i.e. Schizophrenia)
- No substance use disorders except alcohol and nicotine.
- BrAC (Breath Alcohol) = 0.00 mg/dl in each of the assessments.
- No traces of alcohol consumption using urine test strips.
- No contraindications for TMS therapy.
Exclusion Criteria11
- Individuals with symptoms of severe agitation or who are unable to cooperate in the study
- History of epilepsy
- Sudden onset of stroke, focal neurological findings such as hemiparesis, sensory loss, visual field deficits and lack of coordination.
- Seizures or gait disturbances
- History of severe psychiatric disorders.
- Alterations in a conventional electroencephalogram.
- Pacemakers or intracranial metallic objects.
- Elimination criteria
- At the subject's request
- The presence of adverse incidents that deteriorate the subject's health and would limit continuation of rTMS treatment.

Interventions
The investigators will use a Magstim Rapid 2 stimulator, Airfilled coil (AFC), 8 shape (magnetic field of 0.8 Teslas, 3Kg, pulse 0.5 ms) Each patient will receive high frequency 10 Hz stimulation at 100% of motor threshold over the dorsolateral prefrontal cortex (DLPFC) at 1500 pulses per session with 30 trains of 5 seconds and 0.5 ms stimuli and an inter-train distance of 15 seconds. In 2 daily sessions 4 days a week for 4 weeks.
The investigators will use a Magstim Rapid 2 stimulator, Airfilled coil (AFC), 8 shape (magnetic field of 0.8 Teslas, 3Kg, pulse 0.5 ms) Each patient will receive consistent treatment in 2 sessions a day for 20 consecutive business days for 4 weeks. The coil will be placed on the vertex target location.
