Every traumatic experience triggers the cognitive functions. Among the people who have experienced a trauma, the cognitive functions are diminished and these people are exposed to the negative effects of it. People with the diminished cognitive functions are especially sensitive to the PTSD occurrence. Aim. The aim of this study was to evaluate selected cognitive functions with the use of particular neurological tests among the people who have experienced domestic violence. Additionally, it was to specify the influence of the occurrence of PTSD and depression symptoms on the cognitive functions of the victims. Methods. 1.
