The aim of the investigation was to determine the difference between the severities of the symptom’s in PTSD with and without the history of TBI.

The estimation of the PTSD in 60 patients was performed using the CAPS-DX. The estimation of the TBI was performed using the Glasgow Coma Scale. The data were analysed using ANOVA and PostHoc analysis.

Severity of the reexperiencing symptoms were higher in PTSD with TBI vs PTSD w/o TBI: in nightmares, reexperiencing, psychological distress (p<0,05), in intrusive recollections and in total score of reexperiencing symptoms (p<0,01). PostHoc analysis showed higher scores of intrusive recollections (p<0,01) and psychological distress (p<0,05) in PTSD with moderate/severe TBI vs PTSD w/o TBI

Severity of the avoidance symptoms were higher in PTSD with moderate/severe TBI vs PTSD w/o TBI: in avoidance of thoughts, avoidance of activities (p<0,05), in detachment and in total avoidance symptom’s scores in PTSD with moderate/severe TBI vs PTSD w/o TBI. PostHoc analysis showed higher score of detachment in PTSD with mild TBI vs PTSD w/o TBI.

Severity of hyperarousal symptoms were higher in PTSD with TBI: in sleep disturbances, difficulty concentrating (p<0,05), and in total huperarousal symptom’s score (p<0,01). PostHoc analysis showed greater severity of sleep disturbances in PTSD with moderate/severe TBI vs PTSD with mild TBI (p<0,05), and in PTSD without TBI (p<0,01), and greater score of difficulties concentrating (p<0,01) and total huperarousal symptom’s (p<0,05) in PTSD with mild TBI vs PTSD without TBI.
