Principal Investigator: Brian Berman, MD

The overall goal of this proposed research is to investigate the effects of a non-invasive brain stimulation technique called transcranial electrical stimulation (tES) on brain network function and symptoms in patients who have been diagnosed with isolated focal dystonia.

Dystonia Patients are ineligible if the following apply:

  • Anything that would prevent you for having an MRI scan (pregnancy, metal in the body).
  • Anything that would prevent you from being able to receive tES and/or TMS (history of seizures, pregnancy).
  • Any untreated neurological or psychiatric condition or any significant systemic medical diseases (heart failure, liver failure, etc).
  • Evidence of any potentially confounding neurological disorder.
  • Evidence of significant cognitive impairment.
