title: Multiplex developmental disorder.
abstract: BACKGROUND
  Multiplex developmental disorder is a term that was suggested 20 years ago to describe the onset of developmental deficits in affective modulation, social behavior and social sensitivity combined with thinking disorder with bizarre ideas. With the recent validation of these diagnostic criteria, new interest in this disorder has emerged.
  
  
  RESULTS
  We reviewed the background and the difficulties in classifying this subgroup of patients. We also describe a representative case of multiplex developmental disorder and discuss the diagnosis.
  
  
  CONCLUSIONS
  This article emphasizes the importance of investigating this subgroup of patients and encourages reports of such cases in Israel.
