The study of biomarkers of the considered pathological condition using proton magnetic resonance spectroscopy as indicators amenable to objective assessment and measurement determines the practical relevance of this work.</p> <p><bold>Aim.</bold> The aim of the study was to determine the role and place of proton magnetic resonance spectroscopy in clinical practice in children with mental and speech retardation associated with temporal lobe epilepsy.</p> <p><bold>Materials and methods.</bold> 37 children aged 2 to 10 years were studied. Of these, 15 children with a diagnosis of “mental and speech development delay, structural focal temporal epilepsy” were included in the first comparison group. The second comparison group consisted of 12 children without CNS pathology undergoing 1H-MRI examination to exclude somatic diseases. The third comparison group consisted of 10 children with “structural focal temporal epilepsy”, without mental and speech development delay.</p> <p><bold>Discussion.</bold> Multivoxel proton magnetic resonance spectroscopy (method PRESS) was used to determine the concentration of neurometabolites in the brain tissues of patients. In patients with mental and speech development delay associated with temporal epilepsy, a decrease in the ratio of NAA/Cr concentrations (<italic>p</italic> &lt; 0.05) was revealed in the postcentral gyrus on the right, temporal lobe on the right and hippocampus and inner capsule on both sides, due to a decrease in the concentration of N-acetylaspartate; an increase in the ratio of Cho/Cr concentrations (<italic>p</italic> &lt; 0.05) in the prefrontal cortex, postcentral gyrus and inner capsule on both sides, due to an increase in the concentration of choline. Two patients also showed lipid peaks on the lesion side when compared with EEG data.</p> <p><bold>Conclusions.</bold> The revealed metabolic changes in patients with delayed mental and speech development associated with temporal lobe epilepsy may be useful as an additional method of differential diagnosis with other forms of mental and speech development delay.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Актуальность. </bold>Одна из причин задержки психоречевого развития — эпилепсия, среди форм которой особое место занимает фокальная височная эпилепсия. Изучение биомаркеров рассматриваемого патологического состояния с помощью протонной магнитно-резонансной спектроскопии как показателей, поддающихся объективной оценке и измерению, определяет практическую актуальность данной работы.</p> <p><bold>Цель исследования</bold> — определить роль и место протонной магнитно-резонансной спектроскопии в клинической практике у детей с задержкой психоречевого развития, ассоциированной с височной эпилепсией.</p> <p><bold>Материалы и методы.</bold> Исследовано 37 детей в возрасте от 2 до 10 лет, из них 15 детей с диагнозом «Задержка психоречевого развития, структурная фокальная височная эпилепсия» вошли в первую группу сравнения. Вторую группу сравнения составили 12 детей без патологии центральной нервной системы, проходящие обследование методом протонной магнитно-резонансной спектроскопии для исключения соматических заболеваний. Третью группу сравнения составили 10 детей со структурной фокальной височной эпилепсией, без задержки психоречевого развития.</p> <p><bold>Обсуждение. </bold>Для определения концентрации нейрометаболитов в тканях головного мозга у пациентов использовали мультивоксельную протонную магнитно-резонансную спектроскопию (методом PRESS). У пациентов с задержкой психоречевого развития, ассоциированной с височной эпилепсией, выявилось снижение соотношения концентраций NAA/Cr (<italic>p</italic> &lt; 0,05) в постцентральной извилине справа, височной доле справа и гиппокампах и внутренней капсуле с обеих сторон за счет снижения концентрации N-ацетиласпартата; увеличение соотношения концентраций Cho/Cr (<italic>p</italic> &lt; 0,05) в префронтальной коре, постцентральных извилинах и внутренней капсуле с обеих сторон за счет повышения концентрации холина. У двух пациентов также обнаружены пики липидов на стороне поражения при сопоставлении с данными электроэнцефалограммы.</p> <p><bold>Заключение. </bold>Протонная магнитно-резонансная спектроскопия с учетом выявленных метаболических изменений у пациентов с задержкой психоречевого развития, ассоциированной с височной эпилепсией, может быть использована как дополнительный метод дифференциальной диагностики с другими формами задержки психоречевого развития.</p></trans-abstract><trans-abstract xml:lang="zh"><p/></trans-abstract><kwd-group xml:lang="en"><kwd>mental retardation</kwd><kwd>speech delays</kwd><kwd>epilepsy</kwd><kwd>magnetic resonance imaging</kwd><kwd>proton magnetic resonance spectroscopy</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>задержка психического развития</kwd><kwd>задержка речевого развития</kwd><kwd>эпилепсия</kwd><kwd>магнитно-резонансная томография</kwd><kwd>протонная магнитно-резонансная спектроскопия</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Guzeva VI, Artem’eva SB, Batysheva TT, et al.
