2 Pediatric-Onset Bipolar Disorder National Trends in the Outpatient Treatment of Children and Adolescents with Antipsychotic Drugs Olfson et al. Arch Gen Psychiatry. 2006;63: Conclusions: There has been a sharp national increase in antipsychotic treatment among children and adolescents in office-based medical practice. Second-generation antipsychotics are being widely prescribed, and emerging empirical evidence provides a base of support that is limited to short-term safety and efficacy.

7 Why Treat? Treatment Risk versus Benefit includes the risk of not treating with attendant: Suicide attempts and completed suicide Substance Abuse and Addiction Reckless Behavior with Arrest and other consequences

8 Bipolar adults with childhood and adolescent onset had more lifetime suicide attempts and violence N= Child Adolescent Adult Suicide Attempts Violence Psychotic Features Perlis, Miyahara, Marangell, Wisniewski, Ostacher, DelBello, Bowden, Sachs, Nierenberg, Biol Psych 2004;55:

9 Why Treat? Early-Onset Bipolar Disorder and Treatment Delay Are Risk Factors for Poor Outcome in Adulthood Post et al 2010 Methods N=529 bipolar oupatients mean age 42 years Prospective Life Charting for 4 years Results: 50% had illness onset in childhood or adolescence versus adult onset Delay to first treatment correlated inversely with age of onset of illness J Clin Psychiatry 2010;71(7):

10 Why Treat? Early-Onset Bipolar Disorder and Treatment Delay Are Risk Factors for Poor Outcome in Adulthood RESULTS: In year 1, the early onset cases had: greater severity of depression and mania, greater number of episodes and more days depressed, more days of ultradian cycling, fewer days euthymic. After 4 years, the early onset cases still had: greater severity and duration of depression fewer days euthymic. Delay to first treatment was associated with: more time depressed greater severity of depression greater number of episodes more days of ultradian cycling fewer days euthymic J Clin Psychiatry 2010;71(7):

21 How the Literature Review Findings Match Expert Practice Prescribing practices at Massachusetts General Hospital Joseph Biederman, MD Timothy Wilens, MD Janet Wozniak, MD J Child and Adolesc Psychopharmacology, 2009;19(5):

22 Methods Retrospective, unblinded chart review Identified active pediatric patients (age 4-19yo) diagnosed with bipolar disorder or bipolar spectrum disorder Generated an alphabetical patient list for each clinician Collected data for the first ten to twenty patients on the list No exclusion criteria

23 Treatment of Patients Diagnosed with PBD 68% treated for comorbid diagnosis Mean number of total psychotropic medications per patient = 3.0±1.6

24 Treatment Specifically Targeting Pediatric Mania or Mixed State Mean number of anti-manic agents per patient = 1.4±0.77

25 Response to Treatment Diagnosis Mean Pretreatment CGI-S Mean CGI-I CGI-I 2 Mania 5.4± ±0.8 80% Mixed state 5.7± ±0.7 57% Overall 5.2± ±0.7 66%

26 Summary of Expert Prescribing Practice Most patients require combination treatment SGA s were the most commonly prescribed class for both monotherapy and combination therapy SGA clinical response rate was similar to RCT s Potter et al. 2009

27 Literature vs. Expert Practice in the Treatment of Mania Evidence supports SGA monotherapy in PBD 66% response rate in 8 RCT s 66% of experts use SGA s for monotherapy Combination therapy requires further research Only 1 RCT Experts frequently prescribe combination pharmacotherapy

28 Adverse Events One-year incidence rates of tardive dyskinesia in children and adolescents treated with second-generation antipsychotics: a systematic review Correll, et al JChildAdolescPsychopharm 2007;17(5): N=783 Results across 10 studies suggest relatively low 1-year TD rates in pediatric patients treated with SGAs. However, the available data base is limited by the small sample size of studies with SGAs other than risperidone and by the use of relatively low doses, which may have obscured a potentially greater risk for TD in children and adolescents treated with higher total SGA doses and for longer durations. Three new cases of TD emerged during long-term treatment with SGAs of up to 3 years, resulting in crude and annualized TD rates of 0.38%. In the two cases with information, TD resolved within weeks after antipsychotic discontinuation.

29 Adverse Events Weight gain and metabolic risks associated with antipsychotic medications in children and adolescents Correll et al JChildAdolescPsychopharm 2011 Dec;21(6): N=34 studies olanzapine 3.8 to 16.2 kg (n=353) clozapine kg (n=97) risperidone kg (n=571) quetiapine kg (n=133) aripiprazole kg (n=451)

35 Euthymic youths with bipolar disorder and ADHD may benefit from short-term concomitant treatment with methylphenidate A 4-week double-blind, placebo-controlled trial in youths ages 5 to 17 years with bipolar disorder and ADHD, were currently receiving a stable dose of at least one thymoleptic, and while euthymic continued to have clinically significant symptoms of ADHD. Patients received 1 week each of placebo, methylphenidate 5 mg twice daily, methylphenidate 10 mg twice daily, and methylphenidate 15 mg twice daily using a crossover design. Subjects were randomly assigned to receive one of six possible dosing orders. The primary outcome measure was the total score on the parent-completed ADHD RESULTS Lower scores during best dose treatment compared to the week of placebo treatment were found on the ADHD Rating Scale-IV (p <.05), suggesting a therapeutic benefit. A large effect size (Cohen's d = 0.90) was found for methylphenidate. Treatment was generally well tolerated. Rating Scale-IV. Findling et al., J. Am. Acad. Child Adolesc. Psychiatry, 2007;46(11):

38 This study was highly publicized in the major news media and suggest that 2 months of supplementation can have positive effects after one year on psychotic symptoms

39 Our own study shows that omega-3s can treat bipolar disorder in children This result is about 50% what we see with atypical antipsychotic medications, but without the serious or annoying side effects

40 Funding/support: This study was supported by a generous philanthropic donation from Kent and Elizabeth Dauten (Chicago, Illinois). November 2015

43 Natural Help for Depression and Mania? N-Acetyl Cysteine (NAC) is a precursor to glutathione, a potent anti-oxidant (we can t absorb glutathione, so best to ingest the precursor which crosses into the brain and gets converted). Destroys free radicals which lead to cell destruction. NAC is an altered form of the amino acid cysteine. Cysteine is found in high protein foods.
