[Does a legasthenia-syndrom exist? (author's transl)].

Legasthenia means today mainly the pedagogic definition of different forms of reading and writing deficiencies. Closer investigations on children with these symptoms prove however, that beside reading and writing impediments some physical and psychological symptoms can be found. This cluster of symptoms corresponds in some aspects with the so-called Minimal Brain Dysfunction and the Hyperkinesia-Syndrom. In the clinical and psychological investigations of this syndrom we found a high rate of left-handed patients. We suppose, that the pressure to write with the right hand and to read from the left to the right might be one of the reasons of Legasthenia.
