Aggression in patiens with psychosis
Nichtová, Andrea ; Vevera, Jan (advisor) ; Papežová, Hana (referee) ; Končelíková, Dana (referee)
Most psychiatric patients do not behave aggressively, but they very often become victims of aggressive behaviour. However, in the practical part of this work, we focused on the phenomenon of aggressive behaviour in psychotic patients, and we address victimization of psychotic patients in the theoretical part because it is one of the most important predictors of aggressive behaviour not only in psychiatric patients but also in the general population. In the literature, we encounter three basic immediate causes of aggressive behaviour - psychotic, impulsive, and predatory (planned) - which we observed in hospital conditions. Specifically, we focused on impulsive behaviour in aggressive patients, given that it is assumed that psychotic patients have difficulties in this area. The aim of this study was to examine the immediate causes of aggressive behaviour and provide data from the Czech Republic on their prevalence. Another goal was to determine whether the factor structure in our work is consistent with the three hypothesized factors described by Nolan et al. Another goal was to explore impulsive behaviour in psychotic patients in light of the reported reduced impulse control and emotional dysregulation associated with the emergence of aggressive behaviour in psychotic patients. The study aimed to...

Inhibition control in Obsessive-Compulsive Disorder
Francová, Anna ; Preiss, Marek (advisor) ; Juríčková, Veronika (referee)
The response inhibition ability is part of executive functions, which may be defined as a set of higher cognitive processes particularly located in the frontal-subcortical circuits. Since the main obsessive-compulsive disorder (OCD) symptoms seem to be relevant to the inability of inhibiting certain stimuli, it can be assumed that response inhibition in these patients will be disrupted. Studies related to this topic have brought inconsistent results. Our research dealing with OCD patients has focused on two dimensions of the response inhibition - the behavioral inhibition, which generally includes the behavior control (for instance impulse control), and the cognitive interference, which is considered to be the cognitive component of inhibition process and is mostly associated with the control of internal cognitive processes. The first part of our research included the verification of hypothesis, stating that the increased severity of obsession is associated with the degree of disrupted ability of cognitive interference, while the severity of compulsions correlates with the degree of disrupted performance in tests measuring behavioral inhibition. The second research objective was to clarify whether the inhibition response ability was different between patients when the predominance of symptoms was...
