title: Clinical features of children with both ADHD and mania: does ascertainment source make a difference?
abstract: OBJECTIVE
  We evaluated the structural diagnostic results of children ascertained through an ADHD diagnosis with comorbid mania to determine if they have the same phenotype as children ascertained through a mania diagnosis with comorbid ADHD.
  
  
  METHODS
  We compared a sample of children participating in a family genetic study of ADHD to a sample of children ascertained through a study of childhood mania.
  
  
  RESULTS
  Similar correlates of ADHD and mania were observed in children satisfying criteria for both disorders irrespective of ascertainment source.
  
  
  CONCLUSIONS
  Findings suggest that children with mania and ADHD have two disorders, their features not varying with the primary diagnostic focus.
  
  
  CONCLUSIONS
  The results may have been limited by small sample size.
  
  
  CONCLUSIONS
  Because the coexistence of ADHD and mania seriously complicates the course and treatment of children, understanding the compatibility of these disorders has important clinical implications in the management of this population.
