[The concept of minimal brain dysfunction].

The development of the concept of "minimal" brain dysfunctions" can be followed up in the professional literature since the forties. An important contribution was the monograph by O. Kucera et al. (1961) which emphasizes the interaction of the affected child with his social environment. In the seventies and eighties there is a trend to divide the overall concept of minimal brain dysfunctions into individual more accurately defined units comprising certain groups of symptoms (specific disorders of learning, the hyperactivity syndrome, the syndrome of impaired attention, etc.). The article emphasizes the practical usefulness of the term minimal brain dysfunctions in the communication of workers from different disciplines and the necessity to derive from it provisions for the benefit of the affected children at different levels of social practice.
