    Abstract:
    The history of the main ideas of psychogenetic epilepsy-theory is outlined. Using the antithesis of omnipotency and impotency further implications of this theoretical approach are explained. Epileptic patients suffer from a deficient structure of their self and do not overcome infantile obsolutistic thought, behavioral and emotional patterns. Their behavior and symptoms exhibit the characteristics of the "all or nothing schema". In particular conflict solving strategies of epileptics consist either in an exaggerated spirit of toleration or in violent outbursts of aggression. Destructive fits of rage, epileptic fits and psychotic derangements can be understood as manifestations of aggression on ontogenetically earlier developmental stages. From this point of view we studied the influence of the emotional states of epileptics on EEG-background activity and discharges: Conflict-centered interviews were recorded simultaneously in ten epileptic patients with EEG- and video-techniques. FFT-spectralanalysed EEG-data and discharges from visually evaluated EEG-records were correlated with hermeneutic analyses and the ratings of the emotional states. Results show significant correlations between spectral EEG-parameters and aggression, anxiety, sorrow and joy. These results were validated by further studies. Normal aggressive episodes were correlated with an increase of power in all frequency-bands. Epileptic discharges occurred in over or latent aggressive impulses. In the theory of the "Kontinuitätsparadigma" a parallelism of two transitional stages is suggested: ranging from normal to pathological aggression with all its symptoms and from EEG-dynamics in normal aggression to typical discharges in epileptic aggression. The latter represents the extreme pathological end of the stage while the former is its starting-point.
