Objective: The study of bioelectrical brain activity according to EEG in relation to neurological symptoms in boxers which moved mild traumatic brain injury.

Material/Methods: Were examined 48 highly skilled amateur boxers (champions and medalists championships of Ukraine, Europe and the World), duration of boxing training ranged from 5 to 14 years. Surveyed boxers were in the preparatory period. Observed group consisted of 36 men and 12 women aged from 18 to 32 years, the number of boxing matches ranged from 51 to 260, and the number of knock-downs from 2 to 15. Control group consisted of 30 men aged from 18 to 25 years who did not have a history of deferred traumatic brain injury. All patients underwent clinical and neurological study, studied brain activity in the electroencephalograph EEG-16C («DX-Systems», Ukraine).

Results: The main neurological complaints at the boxers were: headache – 34 observations, general weakness – 19, pain in the neck – 15, irritability – 14, loss of memory – 12, sleep disturbance – 10. In the study of the neurological status of the most frequently identified: smoothed the nasolabial folds – 24 observations, deviation of the tongue in the side – 22, unsteadiness in the Romberg position – 15. According to diffuse EEG changes irritative nature found in 34 observations. Local changes in the EEG, in particular, emphasis in the left fronto-temporal region recorded in 18 cases, emphasis in the left temporal region – 1, emphasis in the right fronto-temporal region – 2. The 3 boxers detected paroxysmal activity in the form of bilaterally synchronous sharp waves. Complexes, indicating dysfunction of stem-diencephalic structures, found in 22 observations, dysfunction of diencephalic structures – 7. Specific phenomena of the EEG in the analyzed cases are not detected. In the control group, 5 patients there were diffuse changes irritative nature, characteristics of local changes in the EEG is not revealed.

Conclusion: Clinical manifestations of neurologic symptoms in highly skilled amateur boxers have some connection with the nonspecific electroencephalographic changes that indicate interest in brain structures in response to previous mild traumatic brain injury.
