This two-center, between-subject, randomized, double-masked study (n=20) will provide the first evidence for the antidepressant efficacy of Magnetic Seizure Therapy (MST) and contrast the therapeutic properties and side effects of two forms of MST in patients in a major depressive episode (MDE).

Condition Intervention Phase
Major Depressive Disorder
Device: Magstim Theta
Device: Thymatron System IV
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Further study details as provided by Sarah Lisanby, Duke University Medical Center:

Primary Outcome Measures:
  • Hamilton Rating Scale for Depression (HRSD), 24 item [ Time Frame: A blinded rater will administer the test at Baseline, every Tuesday and Thursday during the treatment course and at the end of the MST course ]

Secondary Outcome Measures:
  • Beck Depression Inventory [ Time Frame: A blinded rater will administer the test at Baseline, every Tuesday and Thursady during the treatment course and at the end of the MST course ]
  • Neuropsychological testings to assess the acute, short term, long term memory effects of the treatments [ Time Frame: A blinded rater will administer various neurospychologiocal tests at various timepoints (baseline, within 3 days following the MST course and at 2 months following the MST course. Treatment Effect Battery (TEB) will be administered at each MST session. ]

Enrollment: 20
Study Start Date: April 2002
Study Completion Date: December 2009
Primary Completion Date: January 2006 (Final data collection date for primary outcome measure)
