Clinical Trial Summary

The purpose of this study is to evaluate the clinical efficacy of transcranial magnetic stimulation in the treatment of Depersonalization Disorder (DPD).


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.

Outcome

Type Measure Description Time frame Safety issue
Primary Cambridge Depersonalization Scale (CDS) 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 No
Secondary Clinical Improvement (CGI-S) 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.
= Normal, not at all ill
= Borderline mentally ill
= Mildly ill
= Moderately ill
= Markedly ill
= Severely ill
= Among the most extremely ill patients
6, 9, or 12 weeks No
