[Performance at school in children suffering of cerebral-convulsion-disease (author's transl)]. 
Investigations were performed into school-certificates of 226 school-children suffering of cerebral-convulsion-disease (Controlgroup 306 healthy children).  Differences between the two groups were significant, the results of the ill children were worse than those of healthy.  The differences increased to the elder children.  Also in schools of backward children the school-certificates between children with and without cerebral convulsion diseases were very different.  The influence of social factors is discussed, hints are given to improve the situation.
