This scientific article provides an analytical review of research on this topic in order to examine the neurocognitive status of people with post-traumatic stress disorder and the specifics of structural changes in the brain as a result of traumatic stress. The article evaluates the procedural, dynamic and substantive aspects of cognitive dysfunction, as well as analyzes the mechanisms of cognitive and regulatory rigidity. The mechanisms of formation of memory deficit and possible causes of disturbance of event chronotope in autobiographical memory are discussed. Macro- and microstructural changes in the brain as a consequence of chronic stress are described. Further directions of neurobiological and neuropsychological research are outlined. The importance of studying the substantive aspects of cognitive functioning and neurocognitive predisposition to stress is substantiated.
