Post-traumatic stress disorder (PTSD) is a serious mental health problem that occurs in people who have witnessed traumatic events such as war, violence or natural disasters. Although there are a variety of treatments for PTSD, not all patients respond to them, highlighting the need to develop new and more effective approaches. In order to study the features of clinical-psychological and somatic-vegetative manifestations of psychosomatic disorders in combatants with PTSD, 55 men aged 20 to 60 were examined. Such a feature of the clinical manifestations of PTSD as a fluctuating (wave-like) flow pattern was confirmed. The identified psychosomatic disorders that were formed as a result of PTSD had a paroxysmal character, and the most common and pronounced were affective and anxiety disorders, which confirmed the kindling theory regarding the epileptiform nature of the process. Thus, the states under investigation arise as a result of disturbances in the electrical activity of the brain, require an appropriate electroencephalographic examination, and further influence on the biopotentials of the brain in order to correct the detected disturbances and rehabilitate persons with PTSD. Taking into account the clinical and pathogenetic features of the formation of PTSD will allow the development of comprehensive programs of therapy and medical and psychological rehabilitation, which will contribute to the recovery and improvement of the quality of life of patients.
