[Delimitation of morbid and nonmorbid querulousness]

The differences are established in the manifestations and course of litigious-paranoid disorders of psychogenic personality-related origin and nonpathological querulousness. Pathologic litigiousness is characterized by a larger constitution-personality predisposition, lesser situational dependence and possibility of psychopathologic classification of querulous manifestations. An excessive intensity and length of querulousness, as related to the objective value of the psychogenesis, the more pronounced trend to litigiousness manifestations, progressive loss of their relation to situational cues, aggressive traits in behavior, are all characteristic of litigious-paranoid disorders. These and other features of litigious-paranoid disorders can be used as differential diagnostic factors in differentiating between pathologic and nonpathologic querulousness.
