Forced normalization

from Wikipedia, the free encyclopedia

When forced normalizing a complete or partial inconspicuousness of is EEG findings referred compared to a previously detectable epileptiform activity in the EEG surface and compared to a pre-existing clinically manifest seizure frequency . Sometimes there is a complete or partial phase of freedom from seizures that coincides with and at the same time as the EEG normalization. However, this phase is occasionally associated with the occurrence of a mental disorder. Paradoxically, the disturbance is temporally tied to the interval between the EEG normalization. Paradoxical normalization is therefore also used synonymously . The mental disorder can escalate into a psychotic episode. It is called alternative psychosis because it is seen not only as an expression of a change in symptoms , but also as a phase-changing and antagonistic course. The Swiss psychiatrist and epileptologist Heinrich Landolt (1917–1971) first coined the term forced normalization in 1955. With regard to the inconsistent, antagonistic psychological-clinical and electrophysiological findings, he used the term "psycho-electrencephalographic correlations".
