Sažetak

Posttraumatic stress disorder (PTSD) is associated with changes in cognitive functions. The aim of the study was to
investigate differences in cognitive abilities between PTSD patients and healthy controls. As PTSD is often accompanied
by comorbidity, the PTSD patients with comorbid diagnoses were also included in our study. The study participants included 254 Croatian combat veterans (60 PTSD and 194 PTSD plus comorbidity) and control group of 125 healthy Croatian military and civilian pilots. The diagnosis of PTSD was made by clinical scale for PTSD assessment (CAPS), while
cognitive abilities were measured by Wechsler intelligence scale (WAIS-III-R) and Rey test (ROCFT). The study results
have confirmed that there is a significant difference in cognitive functions between the PTSD patients and healthy controls
regarding age and education. The PTSD patients (PTSD only and PTSD with comorbidity) have shown lower general
intellectual abilities, reduced capacity of working, numerical and visual memory, and decreased executive functions when
compared to healthy controls. These results are an additional contribution to a better understanding and determination
of changes in cognitive functions that occur in combat PTSD as a result of traumatic stress.
