  4. 4. The greatest controversy in our field?  40X increase in outpatient visits for pediatric bipolar disorder between 1994-95 and 2002-03 (6X increase in prevalence of bipolar diagnosis)  The majority of kids receiving the diagnosis don’t meet traditional DSM-IV criteria for the disorder  Average number of psychotropic medications: 3.4  Average number of medication trials: 6.3 (+/- 3.7)  Medications approved for pediatric bipolar disorder associated with rapid, large increases in weight, lipid, cholesterol elevation, Type 2 diabetes Moreno C, Laje G, Blanco C, et al. Arch. Gen. Psychiatry 64, 1032–1039 (2007).
  5. 5. AACAP Practice Parameters for Assessment and Treatment of Bipolar Disorder (2007)  Pharmacotherapy is the primary treatment in well-defined DSM-IV Bipolar I disorder  A comprehensive treatment plan, combining medications with psychotherapeutic interventions is needed to address the symptomatology and confounding psychosocial factors found in children and adolescents with bipolar disorder J . Am. Acad. Child Adolesc. Psychiatry, 46:1, January 2007
  6. 6. True or False…  The majority of teens admitted to the hospital for the first time for bipolar disorder achieve functional recovery within the first twelve months following their hospitalization.
  7. 7. The answer is…FALSE  41% of teens exhibit functional recovery within a year after initial hospitalization for bipolar disorder  54% experience a syndromic recurrence within twelve months (86% experience syndromic remission)  66% are prescribed SGAs, 56% lithium and/or divalproex, 24% antidepressants, 27% stimulants one year later  35% are adherent to medication (>75% of prescribed doses, 42% “partially adherent (25-75% of doses), 23% non-adherent  Boys twice as likely as girls to achieve symptomatic recovery Delbello MP et al. Am J Psychiatry 2007 Apr; 164(4):582-90
  8. 8. FDA-approved medications for youth with Bipolar Disorder  Risperidone: Bipolar mania (10-17)  Aripiprazole: Bipolar mania (10-17)  Quetiapine: Bipolar mania (10-17)  Olanzapine: (labeling-consider other drugs first) Bipolar mania (13-17)  Lithium Carbonate: Bipolar mania (12-17)… ”grandfathered” indication http://www.fda.gov/downloads/AdvisoryCommittees/CommitteesMeetingMaterials/Pedi atricAdvisoryCommittee/UCM193200.pdf
  9. 9. Second generation antipsychotics in pediatric bipolar disorder:  As of February, 2012: 11 RCTs published –all in 2007 or later  Aside from TEAM, RCTs evaluated kids age 10 and older  Response rates in acute RCTs 45-89%, remission achieved in 25-72%  Treatment-refractory nature of patients enrolled at academic medical centers attenuated magnitude of AEs  Little data examining long-term course on SGAs, efficacy in preventing relapse Hamrin V, Ienacco J. Expert Rev Neurother. 2010;10(7):1053-1088.
  10. 10. Second-generation antipsychotics in acute mania:
  11. 11. Treatment of Early-Age Mania (TEAM) study:  Randomized, 8 week multicenter study of 279 patients ages 6-15 with Bipolar I Disorder  Patients received lithium, divalproex sodium, risperidone  Mean lithium level 1.09 (0.34) mEq/L  Mean divalproex sodium level: 113.6 (23.0) ug/ml  Mean titrated risperidone dose 2.57 (1.21) mg/day Geller et al. Arch Gen Psychiatry 2012 May;69(5):515-28
  12. 12. TEAM Study…results: Geller et al. Arch Gen Psychiatry 2012 May;69(5):515-28
  13. 13. Treatment of Early-Age Mania (TEAM) study:  Risperidone was more efficacious than lithium or divalproex sodium for the initial treatment of childhood mania  Discontinuation rate higher for lithium than for risperidone  Increased weight gain, body mass index, and prolactin level occurred with risperidone vs lithium and divalproex sodium  Thyrotropin level increased in subjects taking lithium Geller et al. Arch Gen Psychiatry 2012 May;69(5):515-28
  14. 14. Risperidone vs. Divalproex
  15. 15. Divalproex vs. Quetiapine
  16. 16. Lithium in pediatric bipolar disorder:  One acute RCT: Li>PBO (46% response rate vs. 8%) …Geller et al., 1998-in JAACAP  Didn’t appear to prevent relapse  Negative RCT in SMD  No significant difference in relapse rates in controlled discontinuation trial vs. placebo (Kafantaris et al., 2004)  Narrow therapeutic window, toxicity in overdose concerns in adolescents Hamrin V, Ienacco J. Expert Rev Neurother. 2010;10(7):1053-1088
  17. 17. Anticonvulsants in pediatric bipolar disorder:  Divalproex sodium: open-label studies have demonstrated response rates of 56-92%, but two RCTs have failed to demonstrate efficacy  Lamotrigine: Three open-label studies suggest 50-60% remission rates, helpful with bipolar depression results confounded by adjunct meds, RCT underway  Topiramate, oxcarbazepine: Negative RCTs Hamrin V, Ienacco J. Expert Rev Neurother. 2010;10(7):1053-1088
  18. 18. Findling’s lithium/divalproex randomized discontinuation study
  19. 19. Comorbidity and pediatric bipolar disorder:  ADHD: 90% in children with bipolar disorder, 60% in teens with bipolar disorder, 13% in adults with bipolar disorder  Prevalence of anxiety disorders: 56-76%  Increased substance abuse risk-greater risk in adolescent-onset vs. childhood onset BPD  4X greater risk of post-traumatic stress disorder Joshi G, Wilens T. Child Adolesc Psychiatric Clin N Am 18 (2009) 291–319
  20. 20. How does comorbidity impact bipolar treatment?  Risperidone>divalproex for kids with comorbid disruptive behavior disorders (DBD)  Patients without DBDs responded equally well to risperidone and divalproex  Kids with high levels of aggression have lower levels of global functioning at treatment completion  TEAM Study: risperidone/lithium response ratios…2.1 for patients with ADHD (1.0 without), 2.3 for non-obese patients (1.1 obese) West AE et al. J Child Adolesc Psychopharmacol 2011 Dec;21(6):545-53
  21. 21. Other studies…  Paliperidone-open-label study (N=15), significant improvement in YMRS, severity of ADHD, psychotic sx.  Quetiapine-open label monotherapy in preschoolers (n=30), school age (N=19) children…response in preschoolers similar to school-age children  Open-label uridine-(N=7) reported to be helpful in adolescents with depression, bipolar disorder Joshi G et al. Psychopharmacology 2013 Jun;227(3):449-58 Joshi G et al. J Affect Disord 2012 Feb;136(3):1143-53 Kondo DG et al. J Child Adolesc Psychopharmacol 2011;21(2):171-75
  22. 22. ECT in adolescent mania?  AACAP Practice Parameters refer to use in treatment refractory adults, pregnancy, catatonia, NMS  “ECT should only be considered for adolescents with well-characterized bipolar I disorder who have severe episodes of mania or depression and are nonresponsive (or unable to take) standard medication therapies.”  One series of 11 patients: One year follow-up-no difference vs. non-ECT control group, two single case reports Taleb O et al. Eur Psychiatry. 2002 Jul;17(4):206-12.
  23. 23. True or false…  Aripiprazole is not associated with significant weight gain when used as monotherapy in youth with bipolar disorder (and other conditions) who are naïve to pharmacotherapy.
  24. 24. The answer is…FALSE Correll, CU et al., JAMA. 2009;302:1765–1773.

  30. 30. Targeting expressed emotion?
  31. 31. So…how do we treat?  Most treatment guidelines/practice parameters are hopelessly outdated, including AACAP practice parameters  Consensus guidelines developed prior to FDA indications for SGA, vast preponderance of existing research  Were study patients truly “bipolar”…or would they be better characterized as DMDD? Kowatch RA et al. J Am Acad Child Adolesc Psychiatry 2005; 44(3);213-35
  32. 32. What are clinicians doing in the community?
  33. 33. Overview of the literature:  Do a very good evaluation to establish the diagnosis first!  SGAs represent first-line pharmacotherapy… aripiprazole probably has fewest metabolic effects  Treat mania first in patients with multiple comorbidities…consider treating ADHD, anxiety, depression once mood stabilization addressed  Is there a role for mood stabilizers in kids without comorbid DBDs?
  34. 34. More treatment thoughts…  I’d consider alternate FDA-approved SGA if patient fails to respond to antipsychotic monotherapy  Very little data on combinations of SGAs and mood stabilizers  CFF-CBT may be very helpful in maintaining adherence, preventing relapse  CBT, school based accommodations, intervention helpful for comorbidities  Side effects MATTER! Prescriptions don’t help when kids refuse medication
  35. 35. What about DMDD? There’s a large group of kids who demonstrate:  Irritability as their predominant mood state  Problems with emotional self-regulation often resulting in aggression  Problems with attention, concentration, academic performance  “At-risk” behaviors…self-injury, substance use, suicidal threats
  36. 36. Kids with DMDD:  Characterized by severe recurrent temper outbursts in response to common stressors  Temper outbursts are manifest verbally and/or behaviorally, such as in the form of verbal rages, or physical aggression towards people or property  The reaction is grossly out of proportion in intensity or duration to the situation or provocation  Responses inconsistent with developmental level  Temper outbursts occur, on average, three or more times per week.  Mood between temper outbursts is persistently negative (irritable, angry, and/or sad).  Negative mood is observable by others (e.g., parents, teachers, peers). DSM-5, American Psychiatric Association, 2013
  37. 37. AACAP concerns about DMDD  Diagnosis imprecise  Syndrome based on work in patients described as “SMD”  Invites criticism for “pathologizing” temper tantrums  Proposed criteria are almost certainly premature  Research hasn’t clarified boundaries between DMDD, ADHD, Oppositional Defiant Disorder and developmentally acceptable behavior  More information needed on how the phenotype changes over the lifespan American Academy of Child and Adolescent Psychiatry, March 30, 2010
  38. 38. What do kids with DMDD look like?  Most have ADHD (86.3%) and ODD (84.2%)  60% at NIMH were diagnosed in community with bipolar disorder  They have a higher than expected prevalence of lifetime anxiety disorders (58.2%) and lifetime major depression (16.4%)  Seven times more likely to be depressed at age 18  Chronic irritability in adolescence predicts MDD, GAD and dysthymia at age 33 Leibenluft E. Am J Psychiatry 2011; 168(2):129-42
  39. 39. What I’ve observed…  They have difficulty with transitions…”cognitive rigidity”  They tend to “ruminate”…indecisive, think too much about things, perseverate  They may experience some improvement in some settings from ADHD medication, but become more irritable, have more meltdowns at home on medication  They do better when they’re busy…inactivity increases irritability  They’re prone to behavioral activation on SSRIs that is often mistaken for mania, hypomania
  40. 40. How I’m treating DMDD…  Conservative use of ADHD medication…limited as much as possible to school day  Meltdowns related to perseverative frustration with inability to achieve desired outcomes may respond to SSRIs, clomipramine  Behavioral activation from SSRIs appears dose- dependent…titrate weekly in small increments  Lots of CBT! Kids need strategies to help manage perseverative thinking  Aggressively dosing accommodations, school-based interventions  SGAs as last resort for severe aggression (risperidone)
