How do you counsel migraine patients interested in implanted neurostimulation devices for migraine?  

I do not routinely recommend these procedures. Specifically to my knowledge, there are no published studies that have looked at the efficacy or safety of Reed or Omega procedures. I counsel patients that there have never been any studies with these procedures so we do not know the efficacy or safety...

I would strongly advise them not to pursue this kind of treatment. We have effective medications for abortive and preventive treatment that are generally well-tolerated and safe. There is no need for devices, implantable or not.
