[Differential language comprehension disorders: results of an explorative study].

OBJECTIVES

Deficits in the expressive language abilities of children are easily observed. Thus these children usually are detected early and receive appropriate professional help. Receptive language abilities are much more difficult to assess, so that deficits either go unnoticed or often are not treated early.

METHODS

In a population of 100 children examined between 1993 and 1995 in the outpatient department for speech, language and behavior problems at the Heckscher Klinik in Munich-Solln and diagnosed as having clinically relevant deficits in language comprehension, we determined the ICD-10 diagnostic category into which the symptom "language comprehension deficit" would best fit.

RESULTS

16 children exhibited language comprehension deficits that were part of a general mental retardation, three other children were diagnosed as having a pervasive developmental disorder. 81 children fulfilled the clinical ICD-10 criteria of a specific receptive language disorder, often in combination with a hyperkinetic syndrome or an emotional disorder. For 42 of these children this diagnosis also was confirmed by test results showing a discrepancy of one standard deviation between the language comprehension test and the non-verbal IQ. The value of language tests for the diagnosis of specific developmental speech and language disorders is discussed.
