Investigating Predictors of Treatment Response in Treatment-Resistant Depression (TRD) With Interleaved TMS/fMRI

This is an interventional treatment trial for Major Depressive Disorder focused on measuring repetitive transcranial magnetic stimulation, rTMS, neurostimulation, biomarker, treatment-resistant Read More

TRD Patient Inclusion Criteria:

Patients will be included if they:

1. are outpatients
2. are voluntary and competent to consent to treatment
3. have a Mini-International Neuropsychiatric Interview (MINI) confirmed diagnosis of MDD, single or recurrent
4. are between the ages of 18 and 80 years
5. have failed to achieve a clinical response to at least one adequate dose of an antidepressant based on an Antidepressant Treatment History Form (ATHF) score of score ≥ 3 in the current episode OR have been unable to tolerate at least 2 separate trials of antidepressants of inadequate dose and duration (ATHF 1 or 2)
6. have a score ≥ 22 on the IDS item
7. have had no increase or initiation of any psychotropic medication in the 4 weeks prior to initiation of rTMS
8. able to adhere to the treatment schedule
9. pass the TMS adult safety screening (TASS) questionnaire

First Episode Depression Inclusion Criteria:

Patients will be included if they:

1. are outpatients
2. are voluntary and competent to consent to treatment
3. have a Mini-International Neuropsychiatric Interview (MINI) confirmed diagnosis of MDD, single or recurrent
4. are between the ages of 18 and 80 years
5. have never received and adequate antidepressant trial and are not currently taking any antidepressant.
6. have a score ≥ 12 on the IDS item
7. are on no psychotropic medication for the 4 weeks prior to initiation of rTMS, with the exception of lorazepam up to 2mg or equivalent dose of benzodiazepine or prescribed sleeping aids including (zopiclone up to 15mg/d, zolpidem up to 10mg/d).
8. able to adhere to the treatment schedule
9. pass the TMS adult safety screening (TASS) questionnaire

Patient Exclusion Criteria:

Patients are excluded if they:

1. have a history of substance dependence or abuse within the last 3 months
2. have a concomitant major unstable medical illness, cardiac pacemaker or implanted medication pump
3. have active suicidal intent
4. are pregnant
5. have a lifetime Mini-International Neuropsychiatric Interview (MINI) diagnosis of bipolar I or II disorder, schizophrenia, schizoaffective disorder, schizophreniform disorder, delusional disorder, or current psychotic symptoms
6. have a MINI diagnosis of obsessive compulsive disorder, post-traumatic stress disorder (current or within the last year), anxiety disorder (generalized anxiety disorder, social anxiety disorder, panic disorder), or dysthymia, assessed by a study investigator to be primary and causing greater impairment than MDD
7. have a diagnosis of any personality disorder, and assessed by a study investigator to be primary and causing greater impairment than MDD
8. have failed a course of ECT in the current episode or previous episode
9. have received rTMS for any previous indication due to the potential compromise of expectancy effects
10. have any significant neurological disorder or insult including, but not limited to: any condition likely to be associated with increased intracranial pressure, space occupying brain lesion, any history of seizure except those therapeutically induced by ECT, cerebral aneurysm, Parkinson's disease, Huntington's chorea, multiple sclerosis, significant head trauma with loss of consciousness for greater than 5 minutes
11. have an intracranial implant (e.g., aneurysm clips, shunts, stimulators, cochlear implants, or electrodes) or any other metal object within or near the head, excluding the mouth, that cannot be safely removed
12. If participating in psychotherapy, must have been in stable treatment for at least 3 months prior to entry into the study, with no anticipation of change in the frequency of therapeutic sessions, or the therapeutic focus over the duration of the study
13. have a clinically significant laboratory abnormality, in the opinion of the one of the principal investigators
14. are currently (or in the last 4 weeks) taking lorazepam greater than 2 mg daily (or equivalent) or any dose of an anticonvulsant, due to the potential to limit rTMS efficacy
15. have a non-correctable clinically significant sensory impairment (i.e., cannot hear well enough to cooperate with interview).
16. have failed more than 5 adequate trials of medication in the current episode.

17. Exclusion criteria for MRI: Those with a history of cranial, thoracic or abdominal surgery, with pacemakers, artificial joins or other metallic implants will be excluded from the MRI scan. Subjects that have agreed to participate in the MRI portion of the study will be pre- screened for any potential metal fragments in the body (particularly in the orbits) if they have had any history of doing metal work or have been involved in use/deployment of ammunitions/explosives, welding, piping etc.). In these cases a CT scan will be performed prior to the MRI scan
