Introduction

Schizophrenia is a mental disorder characterized by loss of cognitive skills. The level of cognitive impairment may affect the degree of impulsiveness, which is defined as a constant willingness to take risks, unplanned activities, rapid decision-making.

Objective

The objective of this study was to analyze the correlation between the level of cognitive functioning and impulsivity.

Methods

The total number of 32 patients (8 female and 15 male) were hospitalized for schizophrenia. They were examined with the Verbal Fluency Test, Trail Making Test (TMT A and B) and Barratt Impulsiveness Scale (BIS-11a). The results of the BIS-11a were converted to the BIS-11.

Results

The mean age of the patients was 34.9 (± 8.75). The average time from the end of education − 10 (± 8.4) years. A higher degree of correlation between abnormal responses in Verbal Fluency (parts measuring phonemic verbal fluency) and impulsiveness (r = 0.61, p = 0.04) was found. These correlation referred also to the impulsiveness resulting from the lack of planning (r = 0.67, p = 0.01), attention impulsiveness (r = 0.46, p = 0.04) and motor impulsiveness (r = 0.48, p = 0.03). The correlation between TMT and BIS (r = −0.1 part, Part B r = −0.25) was not significant (p> 0.05).

Conclusion

The above results are preliminary and the research project will be continued.
