PERSONALITY CHANGES FOLLOWING BRAIN ARTERY ANEURYSM SURGERY

Neuropsychological testing of patients in the course of their recovery from brain injuries enables analysis of cognitive deficiencies and/or emotional changes. The principle study objective was to define organic and/or reactive personality changes and the course of these changes in the function of the time span following brain artery aneurysm surgery in both female and male patients. The study was carried out at the Clinical Department of Neurosurgery, Zagreb University Hospital Center in Zagreb. The data refer to the period from 1989 to 2012 collected in two time intervals, i.e. 11 months and 12-48 months following brain artery aneurysm surgery. Of 72 patients included in the study, there were 28 male and 44 female patients. Neuropsychological testing consisted of clinical interview, clinical assessment of frontal lobe syndrome, Cornell personality questionnaire and Emotional Profile Index. Study results showed evidence of frontal lobe syndrome in 32% of patients on first testing and significant recovery on retesting, when only 17% of patients presented with frontal lobe syndrome. The reactive personality changes found in both testing intervals indicated increased neuroticism. In the first testing period, asthenic syndrome occurred most often, followed by conversion and aggressive- antisocial syndromes, while in the second testing interval asthenic syndrome was most pronounced and conversion and antisocial syndromes showed the same level of expression. The results also showed higher depressive and disorganizing states, which were even more pronounced in the second testing interval. As regards sex differences, the inclination toward cardiovascular somatization and destructiveness was more expressed in females than in males, showing a tendency of aggravation with increasing the time span following surgery. It may be concluded that the study has contributed to better understanding of organic and/or reactive personality changes in patients undergoing brain artery aneurysm surgery.
