Anxiety is a primary symptom in conditions of indefinite fear. Aim of the study is to objectivise the initial fear in patients who decided to take part in a chemo dialysis program because they suffer from chronic renal insufficiency (CRI) N:18.

In the study we examine 753 patients with CRI and who are in the program of chronic haemodialysis in Bosnia and Herzegovina (B&H) in the period 2001. g do 2010. g. The first group consists of patients with Balkan Endemic Nephropathy - BEN n = 348, and control group consists of n = 405 patients with other diagnoses of renal insufficiency (N18). The study is designed as a comparative study. Statistical analysis was done using descriptive and analytical methods.

Socio-demographic data show highly significant difference according to the place of residence between the BEN and N18 groups (c2 = 23.970) P < 0.01, difference in the incidence of renal comorbidity (c2 = 23.970) P < 0.01, family renal comorbidity (c2 = 23.970) P < 0.01, and migrations (c2 = 4.874) P < 0.01. BAI scale has highly significant differences between the two groups P < 0.001, and they are different by the degrees of incidence and significant by variables. HAMD scale has a group significance P < 0.001, and variables point to somatization, general anxiety and depression which is confirmed by general weakness of mental functioning - MMSE.

Anxiety appears in all tested dialysed patients. Structured anxiety with depression results in presuicidal risk
