Hysteria is a polymorphous manifestation pathology in which unconscious psychic conflicts convert symbolically into somatic and psychic symptoms. When patients used to express their symptoms mostly in motor register, we are assisting progressively to the emergence of a new expressive mode of this disease. In fact, passional attitudes of the "Great hysteria" of Charcot and Richer have become exceptional, replaced by rich and sometimes confusing psychic symptoms.
