RESUMO
The administration of psychostimulants to children with psychotic symptoms is controversial. This study reports the stimulant drug response of 5 children, aged 8-15 years, with childhood-onset schizophrenia (COS) and comorbid attention deficit hyperactivity disorder (ADHD). Four COS inpatients were given stimulants for comorbid ADHD after stabilization of psychosis on antipsychotic medication. A fifth COS inpatient received stimulants while still actively psychotic, despite concurrent neuroleptic treatment. Data from the 10-item Brief Conners Teachers Ratings Scale (BCTRS) were examined the week before, and the week after, stimulant addition. A paired t test, conducted using Conners Teachers data from these 4 subjects, indicated significant improvement in ADHD symptoms (p = 0.02). Data obtained from a retrospective chart review indicated no significant worsening of psychosis. The 2 subjects treated with mixed salts of dextroamphetamine sulfate and amphetamine sulfate remained on that medication at 6 months and at the 2-year follow-up. Our results suggest that ADHD comorbid with COS may be safely treated with a stimulant, once the psychosis is stabilized. A systematic investigation of this question may be warranted.
