On the pathogenesis of epileptic and hysterical seizures.

In discussing the problem of differentiating between epileptic and hysterical seizures, the author maintains that electroencephalographic and psychosomatic research indicates that all "epileptiform" seizures are the outcome of a constant interplay of stress and predisposition in which both these factors are of a polygenetic origin. He points out that behind these reactions manifested in consciousness and motility, there lies a fundamental function of defence and that the nature of the seizures occurring is decided by the level of physiogenic or psychogenic regression which prevails in different cases, and which is to a great extent codetermined by a complementary "inviting" level of physical and psychical subevolution (lack of maturation). He holds that the pathogenesis of "epileptiform" seizures is of a truly psychosomatic nature and that this circumstance should be reflected in the therapeutic approach to these disorders.
