Несмотря на очевидную связь имеющихся неврологических расстройств и изменений со стороны психоэмоциональной сферы с нарушениями сна у пациентов с хронической ртутной интоксикацией (ХРИ), до сих пор эти взаимоотношения остаются наименее изученными в клинике нейроинтоксикаций.</p><p>Цель исследования - установить связь между нейрофизиологическими, психологическими и биохимическими показателями у пациентов с профессиональной хронической ртутной интоксикацией, страдающих инсомнией.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Обследованы 36 пациентов в отдалённом периоде ХРИ, средний возраст которых составил 50,7±5,5 года, со средним стажем работы 14,7±1,05 года. Проводилось психологическое обследование с определением уровней депрессии, тревожности и астенического состояния, компьютерная электроэнцефалография (ЭЭГ), когнитивные вызванные потенциалы (КВП), полисомнография, определение уровня нейромедиаторов.</p></sec><sec><title>Результаты</title><p>Результаты. Исследование установило, что астенизация при воздействии ртути происходит вследствие снижения активности лимбико-гипоталамо-ретикулярного комплекса (наличие эквивалентных дипольных источников патологической активности в области диэнцефальных образований (таламус, гипоталамус) в 56,2±5,6% случаев. При исследовании вывялено снижение активности коры головного мозга, подтвержденное ослаблением когерентных связей α-диапазона в затылочных, центральных и лобных отведениях по данным когерентного анализа ЭЭГ и изменениями со стороны КВП. Выявленные изменения со стороны медиаторной системы при ХРИ свидетельствовали об угнетении серотонина и норадреналина при повышенном содержании уровня дофамина в крови. Установлена прямая корреляционная зависимость между уровнем общего времени сна и уровнем серотонина (rs=0,45), обратная зависимость между уровнем депрессии и уровнем гистамина (rs=-0,56).</p></sec><sec><title>Заключение</title><p>Заключение. Проведенные исследования позволили установить механизмы инсомнических нарушений при ХРИ, основными из которых является ослабление тонуса коры головного мозга и изменения нейромедиаторного обмена, а также нарушения взаимодействия ретикулярной системы с лимбическими структурами. Данное исследование показало тесную прямую взаимосвязь нейрофизиологических, психологических и биохимических показателей при реализации инсомнии у пациентов с ХРИ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Despite the apparent connection of the existing neurological disorders and changes in the psycho-emotional sphere with sleep disorders in patients with chronic mercury intoxication (CRI), these relationships remain the least studied in the clinic neurointoxications.</p><p>The study aimed to establish a connection between neurophysiological, biochemical, and psychopathological indicators in patients with occupational chronic mercury intoxication and insomnia.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Thirty-six patients took part in the examination in the remote period of CRI. The average age of patients in this group was 50.7±1.05 years, with an average work experience of 14.7±1.05. The authors carried out a psychological examination to determine the levels of depression, anxiety, asthenic state, computed electroencephalography (EEG), cognitive evoked potentials (CEP), polysomnography, the level of neurotransmitters.</p></sec><sec><title>Results</title><p>Results. The study showed that asthenization, when exposed to mercury, occurs due to a decrease in the limbic-hypothalamo-reticular complex activity (the presence of equivalent dipole sources of pathological activity in the area of diencephalic formations (thalamus, hypothalamus) in 56.2±5.6% of cases. The study showed a decrease in activity cerebral cortex, confirmed by weakening the coherent connections of the α-range in the occipital, central and frontal leads according to the data of coherent EEG analysis and changes on the part of the CEP. There was a direct correlation between the level of total sleep time and the serotonin level (rs=0.45), an inverse relationship between the level of depression and histamine level (rs=-0.56).</p></sec><sec><title>Conclusion</title><p>Conclusion. The studies carried out to make it possible to establish the mechanisms of insomnia disorders in chronic mercury intoxication, which cause a weakening of the tone of the cerebral cortex and changes in neurotransmitter metabolism, as well as disorders of the reticular system with limbic structures. The study showed a close direct relationship between neurophysiological, psychological, and biochemical parameters in implementing insomnia in patients with chronic mercury intoxication.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>инсомния</kwd><kwd>профессиональная хроническая ртутная интоксикация</kwd><kwd>нейрофизиологические</kwd><kwd>психологические показатели</kwd><kwd>нейромедиаторы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>insomnia</kwd><kwd>occupational chronic mercury intoxication</kwd><kwd>neurophysiological</kwd><kwd>psychological indicator</kwd><kwd>neurotransmitters</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">Schutte-Rodin S., Broch L., Buysse D., Dorsey C., Sateia M.
