There are currently no effective approved medications to treat it, which makes finding new treatment options urgent. Repetitive Transcranial Magnetic Stimulation (rTMS), a non-invasive brain stimulation method, has shown promise in reducing cravings and drug use in people with addiction, but its effects on AUD are not well studied.\n\nTo explore this, the investigators plan to conduct a double-blind, sham-controlled study with 20 people diagnosed with AUD. Half will receive real rTMS treatment, and half will receive a placebo-like sham treatment. The treatment targets a specific brain area (the left dorsolateral prefrontal cortex) and will be given 10 times over two weeks.\n\nThe investigators will assess the effectiveness of rTMS by tracking drug cravings, urine test results, and side effects with follow-up over 12 weeks. The investigators also include brain imaging using near-infrared spectroscopy (NIRS) after the treatment.\n\nThe study aims to better understand how rTMS might help reduce amphetamine cravings and improve outcomes, potentially leading to new treatment options for AUD.",[26,27,28,29,30,31,32],"Amphetamine Use Disorders","Amphetamine Use Disorder","Amphetamine Dependence","Amphetamine Abuse","NIRS","rTMS","rTMS Stimulation",[34,35,30],"amphetamine","rtms","NOT_YET_RECRUITING","2025-04-28",{"date":39,"type":40},"2025-05-07","ACTUAL",{"date":42,"type":20},"2025-05-15",{"date":44,"type":20},"2025-12-31",{"name":46,"class":47},"TsaoTun Psychiatric Center, Department of Health, Taiwan","OTHER",1,{"id":50,"slug":51,"hasResults":11,"nctId":52,"briefTitle":53,"officialTitle":54,"acronym":55,"eligibilityCriteria":56,"healthyVolunteers":11,"sex":16,"minAge":57,"maxAge":58,"enrollmentInfo":59,"targetDuration":4,"studyType":61,"phases":4,"briefSummary":62,"conditions":63,"keywords":70,"overallStatus":84,"whyStopped":4,"lastUpdateSubmitDate":85,"lastUpdatePostDateStruct":86,"startDateStruct":88,"completionDateStruct":90,"leadSponsor":92,"locationsCount":48},"100569995","role-of-pavlovian-mechanisms-for-control-over-substance-use-100569995","NCT06701487","Role of Pavlovian Mechanisms for Control Over Substance Use","SFB TRR 265: Losing and Regaining Control Over Drug Intake Work Package 1 of Project B03: General and Specific Pavlovian-to-Instrumental Transfer Effects in a Range of Substance Use Disorders","ReCoDe","Inclusion Criteria:\n\n* Men and women between 18-65 years of age,\n* AUD, and\u002For SUD subjects only: meet 4 or more criteria for DSM-5 alcohol-related and\u002For substance-related (cannabis, amphetamine, methamphetamine or cocaine disorder (not requiring withdrawal as assessed by an independent psychiatrist),\n* Currently using alcohol without a desire for abstinence\n* Ability to consent to the study and complete the questionnaires.\n* Sufficient language(German) and motor skills for using PC\n* existing health insurance\n\nExclusion Criteria:\n\n* Lifetime diagnosis of DSM-5 bipolar disorder or schizophrenia or schizophrenia spectrum disorder (if induced by drugs, it should happen more than a month ago)\n* Current threshold DSM-5 diagnosis of major depressive disorder, or presence of suicidal intention\n* High risk (≤ 26) ASSIST scores in other substances other than alcohol, amphetamine, methamphetamine, cannabis, cocaine, tobacco\n* History of traumatic brain injury or severe neurological disease (such as Dementia, Parkinson's disease, multiple sclerosis, Epilepsy, Meningitis, Stroke)\n* Pregnancy or breastfeeding,\n* Ingestion of medications known to interact with the dopamine system in the 10-day period prior to study participation or less than 4 half-lives after last ingestion (rapid urine test); A detailed list of permitted medication can be added upon request\n* MR contraindications (e.g., pacemakers, metallic or electronic implants, metallic splinters, surgical staples)\n* Color vision deficiency\n* sensorineural hearing loss of 30 dB or greater,\n* Tinnitus and\n* Acute alcohol, substance (cannabis, or methamphetamine, amphetamine, cocaine) intoxication at assessement day verified by breath alcohol tests and drug intoxication verified by rapid urine test.","18 Years","65 Years",{"count":60,"type":20},200,"OBSERVATIONAL","During the first funding period (1st FP), the investigators developed a novel full Pavlovian-to-instrumental transfer (PIT) task that allows assessing both, general and specific PIT to investigate whether specific PIT differs between alcohol use disorder (AUD) and control subjects.
