The study of cognitive evoked potentials (P 300) in boxers with repeated traumatic brain injury

Abstract

Objective. The purpose is to justify the possibility of early detection of cognitive impairment (CI) in boxers with repeated traumatic brain injury (TBI) through the study of cognitive evoked potentials (CEP).Materials and methods. We examined 52 amateur boxers aged 16 to 31 years, who had had repeated mild TBI. The control group consisted of 30 healthy patients of similar age. Held: clinical and neurological examination, magnetic resonance imaging (MRI) of the brain, ultrasonography (USG) of the vessels of the head and neck, computed electroencephalography (CEEG), neuropsychological testing (NPT), registration CEP P300.Results. The latent period (LP) cognitive complex P300 in the normal range occurred in boxers in 55.77% of observations, while in the control group in 86,67%. The amplitude of the cognitive complex P300 in representatives of the main group was in the normal range in 61,54%, the representatives of the control group - 90.00%. Change the settings of CEP representatives of the core group met more frequently among boxers-men over 26 years, heavyweights and those who had more than 200 fights. The data obtained evidence of decreased cognitive function and memory. Assessing the severity of CI in boxers can say that in all the cases had minor violations.Conclusions. The study CEP can be used even in the preclinical stages of CI for early diagnosis and quality control of regenerative processes and evaluate the effectiveness of corrective actions.
