Brief Summary
The project aims to describe and compare the outcome of 12 weeks of prospective, randomized treatment with olanzapine, risperidone or aripiprazole on insulin action in skeletal muscle, liver and adipose tissue, abdominal fat mass, total body and fat-free mass, efficacy for symptoms of aggression and non-metabolic adverse events. Children aged 6-18 will be studied, exploring effects of stimulant therapy and age-related differences in vulnerability to treatment-induced adverse metabolic changes. Aims are addressed by measuring glucose and lipid kinetics with stable isotope tracers, body composition with dual energy x-ray absorptiometry and magnetic resonance imaging (MRI), and standardized assessments of efficacy and adverse events. Relevant data are critically needed to target clinical therapy and basic research, identify medical risks, and guide regulatory decisions in this vulnerable population.

Outcome Measures
Primary Outcomes (2)
Change in DEXA % Body Fat
This study hypothesized that antipsychotic treatment would increase percent total body fat, as measured by whole body dual energy x-ray absorptiometry (DEXA), with larger adverse effects for olanzapine.
12 weeks
Change in Insulin-stimulated Glucose Rate of Disappearance (Glucose Rd)
This study hypothesized that antipsychotic treatment would decrease insulin sensitivity at muscle, as measured by the insulin-stimulated rate of disappearance of glucose (glucose Rd), with larger adverse effects for olanzapine.
12 weeks
Secondary Outcomes (4)
Change in Insulin-stimulated Glycerol Rate of Appearance (Glycerol Ra)

Eligibility Criteria
You may qualify if:
- Aged 6-18 years
- Generally healthy and a score of ≥ 18 on the Aberrant Behavior Checklist in the context of one or more Axis I Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) childhood psychiatric disorders, including conduct disorder, oppositional defiant disorder, disruptive behavior disorder, autism, pervasive developmental disorder, attention deficit disorder, schizophrenia and bipolar affective disorders
- Children's Global Assessment Scale (CGAS) score ≤ 60
- Not previously treated with an antipsychotic; individual subjects with remote, brief prior antipsychotic exposure may be considered for enrollment by the PI on a case by case basis
- Patient assent and informed consent obtained from the parent or guardian
- No clinically significant (based on PI determination) changes in permitted medications (e.g., stimulants and selective serotonin reuptake inhibitors \[SSRIs\]) for approximately 1 month prior to Baseline evaluations
You may not qualify if:
- Active suicidality or primary dx of major depressive disorder
- Any lifetime use of antipsychotics or non-serotonin selective reuptake inhibitor (non-SSRI) anti-depressants
- The presence of any serious medical disorder, based on PI determination, that may confound the assessment of relevant biologic measures or diagnoses, including:
- significant organ system dysfunction;
- endocrine disease, including type 1 or type 2 diabetes mellitus;
- coagulopathy;
- anemia;
- or acute infection.
- Subjects regularly taking any glucose lowering agent, lipid lowering agent, exogenous testosterone, recombinant human growth hormone, or any other endocrine agent that might confound substrate metabolism, oral glucocorticoids (glucocorticoid inhalants and nasal sprays are permitted), antihistamines, sedating antihistamines (non-sedating antihistamines such as but not limited to Claritin (loratadine) and Zyrtec (cetirizine) are permitted), and certain mood stabilizing agents, as some medications may themselves worsen or otherwise alter weight gain, glucose and lipid regulation or otherwise make it difficult to assess the effects of the antipsychotic alone; (note that exposure to many psychotropic agents including stimulants and SSRI's is permitted in order to maintain the generalizability of the sample);
- Intelligence quotient (IQ) \< 70 (based on school records and/or evaluation by clinician)
- current substance abuse
- Past history or currently has dyskinesia
- Stimulant dosage significantly higher (per PI judgment)than the equivalent of approximately 2mg/kg/day methylphenidate equivalent dose.
