    • Major Depressive Disorder
      In the US, prevalence of MDD is 17%, affecting almost 1 in 5 persons. (Kessler, 2005)
      In persons aged 15-44 years, depression is the most disabling medical illness. (Murray 1997)
      Up to 20% of patients fail to respond to first-line therapeutic interventions, (APA ,2000)
      Correct Diagnosis is very important.
    • Summary of Manic and Depressive Symptoms Criteria in DSM-IV-TR Mood Disorders
    • Comorbidity and Symptom Sharing(Gordon, MO, et al, Arch Ophthalmology 2002, 120:714-720)

      TCA, MAOI
    • STAR*D - NIMH Trial
      Sequential Treatment Alternatives to Relieve Depression (STAR*D) Trial
      Largest National Institute of Mental Health (NIMH) prospective study
      Conducted by 14 regional centers across the US
      >4,000 patients over a three year period
      STAR*D Treatment Levels
      Level 1: SSRI-citalopram
      Level 2: Randomized to different arms:
      Switch to another: SSRI-sertraline, venlafaxine XR or bupropion SR
      Switch to cognitive therapy
      Augmentation with bupropion SR or buspirone
      Augmentation with cognitive therapy
      Level 3: Randomized to diff arms
      Switch to mirtazapine or nortriptyline
      Augment with lithium or T3 thyroid hormone
      Level 4: Randomized to one of the ff:
      Switch to MAOI- tranylcypromine
      Switch to combination mirtazapine and venlafaxine XR
    • Response and Remission on STAR*D
      Response rate: 47%
      Remission rates:
      Level 1: 28%-33%
      Level 2: 18%-25% (switch); 30% (with augmentation)
      Level 3: 12%-20%
      Level 4: 7%-14%
      Relapse Rate: 33% to 50% in one year
      Zifra, Gilmer, STAR*D Lessons Learned for Primary Care, Primary Psychiatry , accessed 11/13/2010
    • Treatment Resistant Depression
    • Treatment Resistant Depression
      Most experts would agree that a lack of response following four adequate trials would constitute treatment resistant depression (TRD).
      Dougherty, D. 2010
      The gold standard treatment for TRD is electroconvulsive treatment.
      Dougherty, D, Psych Annals;40: Oct 2010, 458
    • Stages of Treatment Resistance
      Stage I: Failure of at least one adequate trial of one major class of antidepressant
      Stage II: Stage I resistance plus failure of an adequate trial of an antidepressant in a distinctly different class from that used in Stage 1.
      Stage III: Stage II resistance plus failure of an adequate trial of a TCA.
      Stage IV: Stage III resistance plus failure of MAOI trial
      Stage V: Stage IV resistance plus failure of bilateral ECT
      Thase, ME, Rush, AJ, J. Clin Psych 1997

    • Electroconvulsive Therapy (ECT)
      ECT is a procedure in which generalized seizures lasting 25-150 seconds, induced by the passage of an electrical current through the brain under general anesthesia, and muscle relaxation are used for therapeutic purposes.
      Comprehensive Textbook of Psychiatry, Kaplan HI, Sadock BJ, ed, 1995
    • History of ECT
      16th Century – Phillipus Paracelsus
      1764 – Dr. Leopold Auenbrugger of Vienna
      Seizures produced by camphor were used to treat psychosis and mania
      1900 – Dr. Manfred Sakel – Insulin coma therapy
      1938 – development of Electroconvulsive Therapy. Ugo Cerleti and Lucio Bini (Rome, Italy)
      1940 – US started using electroshock therapy.
      1950-1960s – 1970’s = “shock factories”- 300 thousand patients per year
      1970-1980 = One Flew Over the Cuckoo’s Nest
      1990- current: ECT’s quiet comeback (100,000 per year in the US)
    • APA on ECT
      1978 – American Psychiatric Association published landmark report on “Electroconvulsive Therapy”
      1990 – APA published the first edition of The Practice of Electroconvulsive Therapy: Recommendations for Treatment, Training, and Privileging
      2001 – APA published the second edition
    • Mechanism of Action
      Hypothesis: ECT stabilizes dysregulated intracellular signaling linked to multiple transmitter system.
      Alterations in Neurotransmitter and Receptor Function
      NE : Down-regulation and desensitization of B-receptors
      5HT: Upregulation and sensitization of post-synaptic 5HT2 receptors
      Ach: Increased brain and CSF acetylcholine concentration
      Down-regulation of cortical muscarinic receptors
      Could be related to ECT-induced amnesia
      DA: Increased dopamine-mediated behaviors
      Increased CSF levels of brain-derived neurotrophic factor (BDNF)
      Kaplan and Saddock. Comp Textbook of Psych, 1995
    • Indications for ECT
      Primary Use of ECT
      A need for rapid, definitive response because of the severity of a psychiatric or medical condition
      When the risks of other treatments outweigh the risks of ECT
      A history of poor medication response or good ECT response in one or more previous episodes of illness
      The patient’s preference
      Secondary Use of ECT
      Treatment resistance
      Intolerance to or adverse effects with pharmacotherapy
      Deterioration of the patient’s psychiatric or medical condition
      Principal Diagnostic Indications
      Major depressive disorder
      Bipolar disorder, mania
      Schizophrenia, catatonic type
      The Practice of Electroconvulsive Therapy 2nd ed 2001
    • APA Practice Guideline for the Treatment of Patients with Major Depressive Disorder, (Third Edition , October 2010)
      ECT is recommended as a treatment of choice for patients with severe MDD that is not responsive to psychotherapeutic and/or pharmacological interventions, particularly in those with significant impairment or have not responded to numerous medication trials.
      ECT is also recommended for MDD
      With associated psychotic or catatonic features
      Those with urgent need for response (e.g. patients who are suicidal or nutritionally compromised due to refusal of food or fluids)
      Those who prefer ECT or have had a previous positive response to ECT
    • ECT in Special Populations
      ECT may be used regardless of age; doses of medications be modified; ECT stimulus adjusted – seizure threshold increases with age
      Pregnancy and Puerperium
      Obstetric consultation
      Children and adolescents
      Concurrence by two consultants
      Concurrent Medical Illness
      Diabetes Mellitus
    • Suicide Risk and ECT
      Suicide – 11th leading cause of death in the US
      Suicide has biological, psychological, sociological factors
      Suicide affects family, clinical providers, community and society.
      American Psychiatric Association
      Canadian Agence d’Evaluation des Technologies et des Modes d’Intervention en Sante
      U.K. National Institute for Clinical Excellence
      Cited the reduction of suicide risk as a justification for the use of ECT.
      Kellner et al, Am J Psych 2005;162:077-982
    • Relief of Expressed Suicide Intent by ECT
      Consortium for Research in Continuation ECT (CORE Study)
      Multisite, collaborative, NIMH-funded study
      Compare the efficacy of continuation pharmacotherapy (lithium plus nortriptyline) and continuation ECT
      Remission rate for depression in the 355 patients who completed the course of treatment was 85.6%.
      Among 102 patients in the high expressed suicidal intent group who completed acute course of ECT, 87.3% had scores drop to 0.
      Kellner CH, Fink M, Knapp R, et al, Am J Psych 2005;162:977-982
    • Suicidality in Depression Resolved Rapidly With ECT
      Patients received bilateral ECT 3X/week
      After a mean of 2.9 sessions, 95% of patients had HAM-D question 3 ratings of 0
      By the 3rd ECT session, more than 2/3 had become non-suicidal
      By the 7th, 90% were nonsuicidal
      Kellner, C., Poster Presentation, New Clinical Drug Evaluation Unit, 2002
    • ECT Treatment Areas

    • Use of Medications During ECT
      Medications typically continued through the ECT course
      Medications administered prior to each treatment
      Antihypertensive, antiarrhythmics (except lidocaine), antireflux, bronchodilators (except theophylline), glaucoma (except long-acting anticholinesterase agents), corticosteroids
      Medications witheld until after each treatment
      Diuretics, hypoglycemic medications, psychotropic medications
      Medications often decreased or withdrawn prior to or during the ECT course
      Theophylline - status epilepticus
      Lithium – higher risk of delirium and prolonged seizure
      Benzodiazepines, Anticonvulsants medications – reduced seizures
      Monoamine oxidase inhibitors
      Pharmacologic Augmentation of ECT
      Antipsychotic Medications; antidepressant medications
    • Post -ECT Pharmacotherapy
      Compared with placebo, continuation pharmacotherapy with tricyclic antidepressants and/or lithium reduced the rate of relapses in people who had responded to ECT.
      NICE-UK 2010
    • Treatment Following Completion of the Index ECT
      Lack of Response to an Index ECT Course
      Switching to bilateral electrode placement and/or increasing stimulus intensity
      Removing or diminishing the dose of medications with anticonvulsant properties
      Provide at least 10 treatments
    • Adverse Effects of ECT
      Cardiovascular Complications
      Prolonged Seizures
      Prolonged Apnea
      Headache, Muscle soreness, and Nausea
      Treatment-Emergent Mania

    • Memory and Cognitive Deficits
      20 patients in each group (BD with ECT and BD w/o ECT); bilateral treatments; from 6-72 treatments
      Average interval between last ECT treatment and participation= 45 months.
      Cognitive Failure Questionnaire (CFQ)
      Patients who had ECT perceived more memory impairment than did patients who had never received ECT
      California Verbal Learning Test
      Continuous Verbal Memory Task
      Both patient groups had significant impairment on measures of verbal learning and recollection (memory deficits
      BD with ECT performed at lower levels than those w/o ECT

      McQueen G, Parkin, C, et al
      J Psychiatri Neurosci 2007,;32(4):241-249
    • NICE Statement about ECT and Memory
      ECT may cause short- or long-term memory impairment for
      past events (retrograde amnesia) and current events
      (anterograde amnesia).
      As this type of cognitive impairment
      is a feature of many mental health problems it may
      sometimes be difficult to differentiate the effects of ECT
      from those associated with the condition itself. In addition
      there are differences between individuals in the extent of
      memory loss secondary to ECT and their perception of the
      However, this should not detract from the fact that a
      number of individuals find their memory loss extremely
      damaging and for them this negates any benefit from ECT.
      National Institute for Clinical Excellence (NICE-UK) Technology Appraisal 59. Guidance on the use of electroconvulsive therapy, Update May 2010.
    • Mortality from ECT
      There was no evidence to suggest that the mortality
      associated with ECT is greater than that associated with
      minor procedures involving general anaesthetics, and there
      were limited data on mortality extending beyond the trial
      The six reviewed studies that used brain-scanning
      techniques did not provide any evidence that ECT causes
      brain damage.
      (NICE-UK May 2010)
    • Other Neuromodulation Therapies
    • Vagal Nerve Stimulation (VNS)
      VNS is an implanted device.
      Established efficacy in pharmaco-resistant epilepsy.
      Approved for pharmacoresistant epilepsy in Europe in 1994 and in the US in 1997.
      July 2005, FDA approved VNS for severe, chronic or recurrent unipolar and bipolar depression, with a history of failure of the depression to respond to at least four antidepressant interventions.
      Groves, Brown: Neurosci Biobehav Rev, 2005
      Reardon JP et al, Psychiatry , 2006
    • Transcranial Magnetic Stimulation (TMS)
      A noninvasive procedure that uses highly focused magnetic pulses to target specific mood circuits in the brain.
      Recently approved by the Food and Drug Administration for Major depressive disorder.
    • ECT or TMS
      Efficacy – 70%-90% (APA, 2010)
      Memory Effects are more prominent
      Mostly covered by third-party payers -Insurance, Medicare, etc
      Preliminary studies indicate that ECT is more effective than repetitive transcranial magnetic stimulation. (NICE-UK)
      LCOH date: 40% Efficacy
      No significant memory impairment
      Limited third-party coverage
    • Deep Brain Stimulation (DBS)
      DBS is a reversible, neurosurgical procedure consisting of implanting electrodes at specific anatomical location- ventral capsule/ventral striatum (VC/VS) for OCD; and subgenual cingulate gyrus (SCG) for TRD.
      First published report of DBS for psychiatric illness – 1990s
      2009 – FDA approved DBS at VC/VS for intractable OCD under Humanitarian device exemption (HDE)
