Specific developmental disorder of motor function
A disorder in which the main feature is a serious impairment in the development
of motor coordination that is not solely explicable in terms of general intellectual
retardation or of any specific congenital or acquired neurological disorder.
Nevertheless, in most cases a careful clinical examination shows marked
neurodevelopmental immaturities such as choreiform movements of unsupported
limbs or mirror movements and other associated motor features, as well as signs
of impaired fine and gross motor coordination.
Clumsy child syndrome
Developmental:
· coordination disorder
· dyspraxia
Excludes: abnormalities of gait and mobility ( R26.- )
lack of coordination ( R27.- )
· secondary to mental retardation ( F70-F79 )
Mixed specific developmental disorders
A residual category for disorders in which there is some admixture of specific
developmental disorders of speech and language, of scholastic skills, and of
motor function, but in which none predominates sufficiently to constitute the
prime diagnosis. This mixed category should be used only when there is a major
overlap between each of these specific developmental disorders. The disorders
are usually, but not always, associated with some degree of general impairment
of cognitive functions. Thus, the category should be used when there are
dysfunctions meeting the criteria for two or more of F80.-, F81.- and F82.
F84 Pervasive developmental disorders
A group of disorders characterized by qualitative abnormalities in reciprocal
social interactions and in patterns of communication, and by a restricted,
stereotyped, repetitive repertoire of interests and activities. These qualitative
abnormalities are a pervasive feature of the individual's functioning in all
situations.
Use additional code, if desired, to identify any associated medical condition and
mental retardation.
F84.0 Childhood autism
A type of pervasive developmental disorder that is defined by: (a) the presence of
abnormal or impaired development that is manifest before the age of three years,
and (b) the characteristic type of abnormal functioning in all the three areas of
psychopathology: reciprocal social interaction, communication, and restricted,
stereotyped, repetitive behaviour. In addition to these specific diagnostic features,
a range of other nonspecific problems are common, such as phobias, sleeping and
eating disturbances, temper tantrums, and (self-directed) aggression.
