After a discussion of the changes of the @entity2826 concept over the years, the authors describe their own investigation of a total sample of 3280 @entity1 , attending outpatient and inpatient facilities of three counties with a total population of 574,000 inhabitants. The aim of the study was to investigate the frequency, sex distribution, and social class dependency of the @entity2826 -diagnosis and its relationship to @entity146 . The following results were obtained: There is a strong correlation of @entity2826 -diagnosis with age, sex, and social class. @entity2826 was most frequently diagnosed in the age groups of 3-6, 6-9 and 9-12 years, being twice as frequent in @entity1 than in @entity1 and dominating among the lower social classes. The frequency of @entity2826 in the total sample was 11%, taking into consideration all age-classes. @entity2826 was significantly associated only with two @entity146 syndromes: @entity9054 and @entity71 . There was no correlation with @entity74 or @entity11167 , however, a very strong one with @entity245 in development, defined according to the multiaxial classification system. 72% of the @entity1 diagnosed as @entity2826 - @entity1 revealed @entity245 in development. But this high correlation was caused only by two conditions: developmental speech/ @entity3180 and specific @entity1957 . There was no correlation between @entity2826 and specific @entity5545 nor with other specific @entity4207 or mixed @entity245 . Future research in this field should look upon the so-called @entity2826 more in terms of general developmental delays than in terms of brain pathology.
