Only a small number of studies have used quantitative electroencephalography (qEEG) in research of the post-traumatic stress disorder (PTSD). The results are not consistent. The aim of the present investigation was to compare qEEG in combat veterans with and without PTSD. The hypothesis is that differences among qEEG characteristics will be found regarding the presence/absence of PTSD. Seventy-nine combat veterans with PTSD comprised the experimental group and 37 veterans without PTSD were included as controls. After the informed consent, they were investigated by the resting EEG recordings. The results demonstrate that PTSD veterans had decreased alpha power and increased beta power. These results suggest an altered neurobiology in PTSD. Various explanations have been offered for alpha activity decrease observed in PTSD veterans. Increased beta rhythm may play a role as a potential marker in differentiating subtypes of PTSD.

The incidence of aggression and violent behavior in combat veterans varies and can be observed with regard to the presence or absence of post-traumatic stress disorder (PTSD). Significantly greater occurrence of aggression was observed in combat veterans with PTSD compared with those without PTSD. There are various types of aggressive behavior that frequently are combined. Autoaggressive (suicidal) and heteroaggressive (interpersonal violence) behaviors predominate, with dominating verbal aggression and impulsive somatic reactions. Impulsive reactions are more frequently directed toward unknown persons, whereas verbal aggression is mostly aimed at known people. In the occurrence of aggressive behavior in combat veterans with PTSD, important roles are played by education level, low socioeconomic status, maltreatment in childhood, and previous types of violent behavior (before participation in war events).

The obtained data indicate that the prevalence rate in Croatian Type 2 diabetic patients is comparable to findings from other cultural settings. Depressive symptoms can be predicted by psychological rather than disease-related variables. Psychological care for diabetic patients may be necessary to prevent depressive symptomatology.

Delta and theta activity may play a role as a marker in differentiating between positive and negative schizophrenia.
