[Clinical typology of contrast content obsessions in borderline mental diseases]

40 patients were observed (16 men, 24 women, mean age 27 years) with the obsessions of the contrast contents (14-homocidophobia, 18-suicidophobia, 8-combined homo- and suicidophobia). Two types of contrast obsession (CO) were recognized: contrast phobias with anxiety about possibility to commit autodestructive or criminal actions and contrast obsessions with anxious doubts about committing either violence or murder. CO of first type were determined by the fear of lack of self-control and possibility to commit autodestructive or criminal actions. Such obsessions are accompanied by bright images, massive somato-vegetative symptomatology and rapid formation of avoidance behaviour. CO of second type are characterized by pathologic doubts about committing violence or murder and accompanied by strong desire to check again and obsessive self-analysis. CO of first type belong to the spectrum of anxious-phobic disorders and are phobic in their nature; within acute phobic fit, similar in manifestations to a panic attack; they are associated with other phobic disorders and manifest like phobic depressions. On the contrary, CO of second type are true obsessive phenomena, and isolated, combine with obsessions of the repeated control, and with different types of depressions only in half of the cases.
