Introduction to NIMH Studies Disclosure No personal disclosures Off-Label Use of Ketamine What is treatment resistant depression? Failure of at least two antidepressants from different pharmacological classes Of adequate dose and duration In the absence of psychosocial dysfunctionwhose primary treatment is psychotherapy and not medication. Wijeratne et al, Treatment-resistant depression: critique of current approaches, Australian and New Zealand journal of psychiatry 2008

Alternative Treatments Trans magnetic Stimulation (TMS) NeuroStar TMS OReardon JP et al. Efficacy and Safety of TMS in the Acute Treatment of Major Depression: A Multisite RCT. Biol Psychiatry 2007:62:1208-16 Electroconvulsive Therapy (ECT) Oldest, most effective treatment for depression Mechanism of action unknown Seizure a necessary

component of treatment General anesthesia required Confusion/memory loss potential side effects Relapse a major issue rTMS vs. ECT ECT was superior to high frequency rTMS in terms of response (65% vs. 49%) and remission (53% vs. 34%) There was no difference in MMSE between rTMS and ECT in meta-analysis of 10 studies. No significant difference in almost the entire cognitive spectrum except for verbal fluency and complex figure-delayed recall. There are not enough moderate- to long-term studies looking at the cognitive

side effects of rTMS and ECT. -J. Ren Progress in Neuro-psychopharmacology and biological psychiatry 2014 STEP-BD Acute Depression Medication Trial No significant differences on transient remission, durable recovery, or emergent affective switches between groups Thase ME.

STEP BD Adjunctive Treatment of Bipolar TRD For those who failed mood stabilizer + antidepressant, the addition of the following drug did not significantly improve depressive symptoms From Nierenberg et al, AJP 2006;163:210-6) Lithium Light metal, the salt (lithium carbonate) has been used since 1849 for a variety of conditions

Primary treatment for mania (bipolar illness) Adjunctive treatment for unipolar depression One of only 3-4 psychiatric treatments shown to reduce risk of suicide Toxicities: Cardiac, Neuro, Renal, Thyroid, Teratogenic Depression with Psychotic Features Misdiagnosis of psychotic depression is common Delusions or hallucinations Typically mood-congruent Associated with:

Increased severity More frequent hospitalization More frequent suicide Less frequent spontaneous remission Combination pharmacotherapy needed Rothschild et al.

Psychotherapy for (TRD) : A systematic review Current evidence examining the effect of psychotherapy as augmentation or substitute therapy for TRD is sparse and mixed results. Psychotherapy in TRD may: Modify maladaptive cognitions and behaviors Mitigate side effects of antidepressants Patients may prefer to not take medications: help with non-adherence. Trivedi et al.

American Foundation for Suicide Prevention, 2012 Geographic Variation in U.S. Suicide Rates by County Current Treatments Only FDA approved medication for suicidal behavior: clozapine for patients with schizophrenia No FDA approved medication for suicidal thoughts Lithium not FDA approved but evidence of reducing suicidal behaviors Black box warning on SSRIs may have led to decreased depression treatment in adolescents and adults Ting et al., 2012; Deisenhammer et al.
