Commentary. Transcranial Magnetic Stimulation: Does It Matter Where or What or Whom You Target?BERMAN, JOSHUA MD, PhDJournal of Psychiatric Practice: March 2017 - Volume 23 - Issue 2 - p 148–149 doi: 10.1097/PRA.0000000000000222 Clinical Case Discussions Abstract Author Information Repetitive transcranial magnetic stimulation is a promising treatment for depression and possibly for other psychiatric disorders. Clinical trials show a small but significant benefit compared with sham treatment. Occasional patients respond dramatically, as witnessed in the 2 cases presented here of patients with depersonalization symptoms. The guest discussant, Dr Joshua Berman, analyzes the challenges of finding individualized treatment parameters that could make repetitive transcranial magnetic stimulation more predictably effective. BERMAN: Department of Psychiatry, Division of Experimental Therapeutics, Columbia University College of Physicians and Surgeons, New York, NY J.B. was an investigator in a Brainsway clinical trial for deep TMS.
