Deep TMS of Neural Circuits Associated With Stimulant Use Disorder

Inclusion: * Must be within the age range of 25-75. * Participants must meet Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) criteria for moderate to severe MUD (≥4 diagnostic symptoms). * Participants must be able to obtain a Motor Threshold (MT), which will be determined during the screening process. * Participants must have an adequately stable condition and environment to enable attendance at scheduled clinic visits. * Participants must be able to read, verbalize, understand, and voluntarily sign the Informed Consent Form prior to participation in study procedures in English. * If participants are on a medication regimen for comorbid symptoms, that regimen will be stable for the duration of the study and patient will be willing to remain on this regimen during the treatment phase. * Participants must be fluent in English Exclusion criteria: * Transcranial magnetic stimulation (TMS) and magnetic resonance imaging (MRI) contraindications: such as a cardiac pacemaker, cochlear implant, or an implanted device (deep brain stimulation, ferromagnetic metal in the head and body, claustrophobia, pregnant or breastfeeding or other ferromagnetic device/object in the head and body within 30 cm of the treatment coil. * General medical condition, disease, or neurological disorder that interferes with the assessments or participation. * Unable to safely withdraw, at least two weeks prior to treatment, from medications that increase seizure risk. * Current substance abuse as determined by positive toxicology screen * Have a mass lesion, cerebral infarct, or other active CNS disease, including a seizure disorder. * A recent suicide attempt (defined as within the last 30 days) or presence of current suicidal plan or intent. Patients at risk for suicide will be required to establish a written safety plan involving their primary therapist before entering the study. * Severe impediment to vision, hearing and/or hand movement, as this is likely to interfere with the ability to follow study protocols. * Greater than mild traumatic brain injury (defined as greater than 10 minutes loss of consciousness). * Taking benzodiazepines or neuroleptic medications, or any medication known to alter seizure threshold. * Acute or unstable chronic illness. * Current or lifetime history of bipolar disorder or psychosis. * Participation in another concurrent intervention-based clinical trial.
