A heterogeneous group of disorders that share the characteristic of an onset in childhood but otherwise differ in many respects. Some of the conditions represent well-defined syndromes but others are no more than symptom complexes that need inclusion because of their frequency and association with psychosocial problems, and because they cannot be incorporated into other syndromes.

Exclusions

  • breath-holding spells (R06.8)
  • gender identity disorder of childhood (F64.2)
  • Kleine-Levin syndrome (G47.8)
  • obsessive-compulsive disorder (F42.-)
  • sleep disorders due to emotional causes (F51.-)
