EEG-status of patients with the consequences of the brain insults and injuries of different severity levels in the process of cerebral angiogenesis surgical stimulation

The assessment of the expressiveness of cerebral electrogenesis reactive changes depending on hemiparesis severity was made by EEG data in patients with the brain ischemia (consequences of the brain circulatory insufficiency - 17 patients, those of severe craniocerebral injury - 11) during their surgical rehabilitation by the technique of vasoactive osteocranioplasty. In the process of the study it was found that the initial level of EEG-disorders was correlated with the severity level of paretic symptoms. The changes of the cerebral cortex rhythms, observed after the rehabilitation course completion, showed plastic reorganizations in cerebral structures, which had the character of a compensatory-and-adaptive process. The data, obtained in the long-term postoperative process, revealed that the extent of focal slow activity reduction was in inverse proportion to the initial severity of the neurologic deficiency, assessed by the results of EMG-testing. Thus, the data of the studies performed allow to conclude that under the surgical rehabilitative strategy, worked out at RISC "RTO", the initial level of the involvement severity of cerebral structures is one of the factors determining the dynamics of compensatory-and-restorative processes.
