The identification of major hysteria into a special clinical form is considered a significant step forward compared with the pathological division of emotional life into melancholia, hypochondria, epilepsy, hallucinations, delusions and obsessions. It seems at least more correct because it gives a better idea of the painful mental states that arise in certain situations or in a certain mental situation. Moreover, we cannot isolate these forms as separate from weaker and more pronounced manifestations, since the above forms sometimes go through a stage of weakening. They are based on one general clinical principle, which is that any mental function is subject to partial blocking blocked excitation jumps to other nerve pathways and from here various abnormal sensations arise.
