Features of Brain Bioelectric Activity in Adolescents With Autonomic Dysfunction Syndrome and Syncope

There have been determined electroencephalograms (EEG) change variants in adolescents aged 15-17 years with the autonomic dysfunction syndrome (ADS) depending on the character of their complaints - cardiac, cardiac combined with cerebrovascular complaints as well as with a neurocardiogenic syncope in anamnesis with mixed complaints. Exclusion criteria for formation of the sample were signs of epileptic activity and hemodynamically significant electrocardiogram changes. The results indicated a significant fraction of paroxysmal predominantly hypoxic dependent EEG-phenomena and diffuse brain activity changes with a significant dominant EEG-rhythm reduction in adolescents with ADS both with isolated cardiac complaints and with cardiac combined with cerebrovascular complaints. A baseline EEG theta-activity in the anterior brain parts and hypoxic dependent paroxysmal EEG phenomena were most pronounced in adolescents with neurocardiogenic syncope
