Researches of a suicidal risk formation are an actual medical-social problem nowadays, as suicides are one of the leading causes in the structure of premature mortality. A formation of suicidal risk in various groups of patients is studied insufficiently, so an assessment of suicidal risk in patients with neurotic (F41.2, F43) and endogenous depression (F31, F32) was the aim of this investigation.

The methods included a clinico-psychopathological examination and a psychodiagnostical examination (the method of suicidal risk detection and the method for determination of self-consciousness of death (Gavenko V.L. et al., 2001)).

It was defined that patients with neurotic depressions had a high suicidal risk level (27.75 points). The suicidal risk was manifested maximally (29.05 points) in patients with disorders of adaptation (F43), and was 26.45 points in patients with anxiety-depressive disorders (F41.2). An average suicidal risk for patients with endogenous depressions was 28.35 points. A level of self-consciousness of death by a person plays an important role in a suicidal behavior formation. Its low level enhances a risk of auto-aggression. Patients with neurotic depressions have generally higher levels of self-consciousness of death (22.72 points) in comparison with patients with endogenous depressions (21.16 points) that evidences an insufficient anti-suicidal barrier in latter patients and reflects a presence of real auto-aggressive intentions.

It is necessary to take onto account the data obtained in diagnosis and differentiated approaches to therapy and prevention of suicidal risk.
