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.-)

Stereotyped movement disorders

Voluntary, repetitive, stereotyped, nonfunctional (and often rhythmic) movements that do not form part of any recognized psychiatric or neurological condition. When such movements occur as symptoms of some other disorder, only the overall disorder should be recorded. The movements that are of a non self-injurious variety include: body-rocking, head-rocking, hair-plucking, hair-twisting, finger-flicking mannerisms, and hand-flapping. Stereotyped self-injurious behaviour includes repetitive head-banging, face-slapping, eye-poking, and biting of hands, lips or other body parts. All the stereotyped movement disorders occur most frequently in association with mental retardation (when this is the case, both should be recorded). If eye-poking occurs in a child with visual impairment, both should be coded: eye-poking under this category and the visual condition under the appropriate somatic disorder code.

Inclusions

  • Stereotype/habit disorder

Exclusions

  • abnormal involuntary movements (R25.-)
  • movement disorders of organic origin (G20, G21, G22, G23, G24, G25)
  • nail-biting (F98.8)
  • nose-picking (F98.8)
  • stereotypies that are part of a broader psychiatric condition (F00-F95)
  • thumb-sucking (F98.8)
  • tic disorders (F95.-)
  • trichotillomania (F63.3)
