Энергетическое состояние головного мозга при употреблении психоактивных веществ подростками с СДВГ

Энергетическое состояние головного мозга при употреблении психоактивных веществ подростками с СДВГ

Abstract

Проведено исследование уровня постоянных потенциалов головного мозга у подростков с СДВГ, систематически употребляющих психоактивные вещества (ПАВ). Выявлены клинико-психофизиологические особенности в формировании зависимости. Употребление ПАВ сопровождается повышением функциональной активности головного мозга, особенно в младшем и среднем подростковом возрасте, происходит нарушение принципа «куполообразности» распределения уровня постоянных потенциалов, что свидетельствует о негативном влиянии ПАВ на подкорковые структуры. Снижается энергообеспечение лобных отделов головного мозга по сравнению с другими отделами, что клинически проявляется возрастающими нарушениями внимания и поведения. С доминированием правого полушария связаны аффективные нарушения и высокая эмоциональная лабильность. Чем раньше происходит вовлечение в употребление ПАВ, тем более негативное влияние оказывают ПАВ на функционирование и созревание головного мозга подростка.

The paper studied the level of cerebral DC potentials in adolescents with ADHD using psychoactive substances (PAS). It was revealed that the formation of substance dependence in adolescents with ADHD has its clinical and physiological peculiarities. Substance use leads to increased functional activity of the brain, particularly in early and mid-teens, and violation of the principle of “dome-shaped” distribution of cerebral DC potentials, which indicates negative effects of PAS on subcortical structures. Energy supply to the frontal areas of the brain is reduced as compared to other areas, which is clinically presented by intensified attention deficit and behavioural disorders. Dominance of the right hemisphere is connected with affective disorders and high emotional lability. The earlier the onset of substance use, the more adverse the effect on the functioning and maturation of the adolescent brain.
