Biological antagonism and epileptic psychosis

The controversial literature about the biological antagonism between schizophrenia and epilepsy involves at least two areas of clinical interest. Firstly, it is frequently stated that convulsive treatment was introduced into psychiatry for the management of psychosis because of this antagonism, and secondly, it has a bearing on the topics of 'alternative psychosis' and 'forced normalisation', as reported in the epilepsy literature. In addition to these, the subject is of theoretical interest in its relationship to other biological antagonisms that may be found in nature, but closer examination of the literature suggests that some of the discussions and controversies surrounding this problem are based on assumptions that may be incorrect. One possible reason for this may be the fact that much of the original work was written in German, and we propose therefore to give a brief account of the origins of the theories, as derived from their original sources.
