Beskrivelse
Inclusion Criteria:
SCREENING/DIAGNOSTIC REQUIREMENTS:
- Male or female outpatients, ages 18-50 (some literature has shown increasing cortical distance with age that may affect treatment outcome
- Hamilton Rating Scale of Depression (HRSD-24) > 18
- New onset major depression or untreated recurrent major depression per DSM-IV-TR38 criteria.
- Not taking antidepressant medication or any other psychotropic medication
- Using an adequate contraceptive method
- Able to give informed consent
- Available for 4 weeks of daily therapy, working hours, Mon.-Fri.
- English-speaking
Exclusion Criteria:
DIAGNOSTIC EXCLUSIONS:
- Co-morbid psychiatric diagnosis of bipolar disorder, acute OCD, schizophrenia or schizoaffective or concurrent treatment with outpatient ECT, or personality disorder or MDD with suicidal ideation as determined by history and/or by P.I. examination requiring hospital admission or referral for acute care.
- Previous failure to respond to treatment with rTMS
- Failure to achieve satisfactory improvement in depression after two or more adequate trials of antidepressant medications.
MEDICAL EXCLUSIONS:
- Patients newly diagnosed with thyroid dysfunction
- History of drug and/or ETOH dependence
- History of seizures
- History of head injury with loss of consciousness > 5 minutes
- Any implantable metal object in the skull or near their head
- Any implantable devices such as a cardiac pacemaker, vagal nerve stimulator, etc.
- Positive urine pregnancy test
- Severe migraine headaches uncontrolled with routine non-narcotic medication
- Any medical condition in the opinion of the Investigator that might confound the results of the study Contraindications to fcMRI procedure
- Intake of NSAIDS, narcotic or muscle relaxants within 72 hours of the fMRI protocol.
- Claustrophobia.
- Left-handedness (may influence cerebral cortical hemispheric dominance).
- Inability to tolerate, or medical contraindication to MRI testing (e.g. metal prostheses or implants, history of claustrophobia)
PROTOCOL SPECIFIC EXCLUSIONS:
- Unable to determine motor threshold for determining treatment dose with rTMS device
- Mini Mental Status Exam (MMSE)70 score < 24.

Eksperimentel: Transcranial Magnetic Stimulation
Open-label transcranial magnetic stimulation

Four 100-second trains and then one 65-second train, with 30-second inter-train intervals, at 1 Hz and 120% of the resting motor threshold will be applied over the right dorsolateral prefrontal cortex.
Subsequently, twenty-five 30-second trains, with a 30-second inter-train interval, at 10 Hz and 120% of the resting motor threshold will be applied over the left dorsolateral prefrontal cortex.

Hamilton Depression Rating Scale-24 Point Version (HDRS-24)
Tidsramme: At study entry and within 2 days of exiting 4 weeks of rTMS treatment
|
HDRS-24 will be used to measure response to rTMS treatment.
A 50% decrease in HDRS-24 score will indicate treatment response; HDRS-24 < 10 will indicate remission.
