The predictable future of treatments to stutter? Deep Brain Stimulation or Transcranial Magnetic Stimulation

The predictable future of treatments to stutter? Deep Brain Stimulation or Transcranial Magnetic Stimulation Since we have known stutter is induced from linguistic system's misfiring and abnormal psychologic activities, and the former needs us to alter abnormal brain structures (can't detail them) to eradicate stutter, it occurred to me that DBS and TMS can have similar effects. So I'm wondering what treatment will be the future treatment to stutter. I gotta say deliberate neurological repairments will be necessary cuz we can't expect our linguistic neuros to be fixed up spontaneously. Or any special surgery only for stutter? I'm not very knowledgable of it, sorry.
