CategoryF98Other behavioural and emotional disorders with onset usually occurring in childhood and adolescenceOpen

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.-)

Stuttering [stammering]

Speech that is characterized by frequent repetition or prolongation of sounds or syllables or words, or by frequent hesitations or pauses that disrupt the rhythmic flow of speech. It should be classified as a disorder only if its severity is such as to markedly disturb the fluency of speech.
