title: [Cognitive functions and personality traits in patients with brain tumors: the role of lesion localization].
abstract: Personality traits and cognitive functions were studied depending on a tumor localization in the brain in 21 neurosurgical patients and the results were compared with a control group. In patients with brain damage, mostly affected were personality traits associated with emotion regulation and social interaction (neuroticism, psychoticism and social conformity). Increases in psychoticism and decreases in neuroticism were more expressed in patients with a left-hemisphere localization of tumors. The tumor-induced decrease in cognitive abilities was more presented in performing figurative tasks and less in verbal ones. Verbal functions were more decreased in the group with frontal localization of tumor compared to that with parietal localization.
