This monograph deals exclusively with the social and medicolegal aspects of epidemic encephalitis and has been written for the benefit of those who are called on to give expert opinion or advice in the many troublesome situations in which the unfortunate victims of chronic encephalitis find themselves. It is written with reference to German social conditions and laws, but the same problems exist in all civilized countries. On account of the recognized advanced state of German social legislation, much no doubt can be learned from the handling of these problems in Germany. The criminal aspects, legal responsibility, schooling, institutional care, indications for abortion, relation to insurance, guardianship, and capacity to drive automobiles are all treated with usual German thoroughness.
