Detailed Description

This study is a research trial of an outpatient, non-medication, non-invasive investigational treatment called Transcranial Magnetic Stimulation (TMS). TMS applies a magnetic field to the brain for a brief period of time. TMS is a procedure that involves 30 minute-long daily sessions every weekday for a series of weeks. The investigators are testing whether TMS can treat Depersonalization Disorder (DPD).

This is an open-label study. All patients will receive active treatment. DPD symptoms will be monitored through weekly self-report questionnaires as well clinical ratings with a doctor.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Cambridge Depersonalization Scale (CDS)
Time Frame: 6, 9, or 12 weeks

Change on CDS from baseline. Scale item number: 29 Item score range: Frequency: 0 - 4, Duration: 0-5 Minimum CDS score: 0 Maximum CDS score: 261

Higher scores indicate the presence of high symptom severity. Decrease in scores from baseline reflects clinical symptom improvement.
6, 9, or 12 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Clinical Improvement (CGI-S)
Time Frame: 6, 9, or 12 weeks

Minimum CGI-S score: 1 Maximum CGI-S score: 7

Higher scores indicate the presence of high symptom severity. Decrease in scores from baseline reflects clinical symptom improvement.

Patients will be classified as responders with a CGI-S = 1 or 2; and partial responders CGI-S = 3.

  1. = Normal, not at all ill
  2. = Borderline mentally ill
  3. = Mildly ill
  4. = Moderately ill
  5. = Markedly ill
  6. = Severely ill
  7. = Among the most extremely ill patients
6, 9, or 12 weeks
