В статье подводятся итоги начального этапа подобного исследования.Цель: определение нейрофизиологического профиля больных шизофренией юношеского возраста с длительностью катамнеза 20-25 лет.Материал и методы: фоновую ЭЭГ и слуховые вызванные потенциалы в парадигме oddball регистрировали у 18 больных шизофренией с манифестацией заболевания в юношеском возрасте и длительностью катамнеза более 20 лет и 10 подобранных по возрасту и полу психически здоровых испытуемых (контроль). Анализировали спектральную мощность тета-, альфа- и бета-1-ритмов ЭЭГ, амплитуды и латентные периоды волны Р300. Результаты и их обсуждение: по сравнению с контролем у больных выявлена большая спектральная мощность в тета-диапазоне ЭЭГ при отсутствии статистически значимых различий по амплитудам и латентным периодам волны Р300 в теменных областях. Статистически значимых корреляций нейрофизиологических и клинических показателей выявлено не было. Полученные данные предполагают, что патологические процессы, находящие свое отражение в изменениях тестируемых нейрофизиологических характеристиках, в той или иной степени компенсированы у пациентов с длительным течением заболевания и не определяют выраженность психопатологических расстройств на данном этапе.</p></abstract><trans-abstract xml:lang="en"><p>Introduction: the study of brain functionality with neurophysiological method is one of the informative approaches to discrimination of additional diagnostic and prognostic markers of the disease. The article summarizes the findings of the initial stage of such investigation.Aims was to determine the neurophysiological profile of youth schizophrenia patients with the long-term follow-up 20-25 years. Methods: background EEG and auditory evoked potentials in oddball paradigm were recorded in 18 patients with youth schizo- phrenia (illness duration more than 20 years) and 10 age and sex matched mentally healthy subjects. Spectral power of theta, alphaand beta1 rhythms and amplitude and latencies of P300 were analyzed.Results and discussion: as compared to controls, the patients had higher spectral power of theta-rhythm but no differences by amplitude or latency of parietal P300. There were no statistically significant correlations between neurophysiological and clinical characteristics. The findings assume that pathological processes in base of tested neurophysiological characteristics are compen- sated at some extent in the patients with long-term follow-up of youth schizophrenia and do not determine the psychopathology at this illness stage.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>шизофрения</kwd><kwd>отдаленный катамнез</kwd><kwd>фоновая ЭЭГ</kwd><kwd>вызванные потенциалы в парадигме oddball</kwd><kwd>тета-ритм</kwd><kwd>Р300</kwd><kwd>schizophrenia</kwd><kwd>long-term follow-up</kwd><kwd>background EEG</kwd><kwd>evoked potential in oddball paradigm</kwd><kwd>theta rhythm</kwd><kwd>P300</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Itil T.M.
