Drop attacks are the commonest and the most disabling type of seizures. Resective surgery is often not possible in LGS as the electroencephalogram (EEG) abnormalities are usually multifocal and generalized, and magnetic resonance image is often either normal or multilesional. We report a case of LGS with bilateral parieto-occipital gliosis where EEG before and after callosotomy demonstrated synchronized bilateral interictal epileptiform discharges and ictal discharges becoming desynchronized and running down. This phenomenon emphasizes the role of the corpus callosum in secondary bilateral synchrony.</p></abstract><trans-abstract xml:lang="ru"><p>Синдром Леннокса–Гасто (СЛГ) – это эпилептическая энцефалопатия, характеризующаяся задержкой умствен- ного развития и трудноизлечимыми приступами нескольких типов, преимущественно тоническими. Приступы падения являются наиболее распространенным и наиболее инвалидизирующим типом припадков. При СЛГ ре- зекционная хирургия часто невозможна, поскольку аномалии электроэнцефалограммы (ЭЭГ) обычно много- очаговые и генерализованные, а магнитно-резонансные томограммы часто бывают нормальными или свиде- тельствуют о множественных поражениях. Мы приводим клинический случай СЛГ с двусторонним париетозаты- лочным глиозом. При выполнении ЭЭГ до и после каллозотомии регистрировались синхронизированные двусто- ронние интериктальные эпилептиформные разряды, а иктальные разряды сократились и десинхронизировались. Указанный феномен подчеркивает роль мозолистого тела во вторичной билатеральной синхронизации.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Эпилептическая энцефалопатия</kwd><kwd>cиндром Леннокса–Гасто</kwd><kwd>мозолистое тело</kwd><kwd>каллозотомия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Epileptic encephalopathy</kwd><kwd>Lennox–Gastaut syndrome</kwd><kwd>corpus callosum</kwd><kwd>callosotomy</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">Mathews M.S., Linskey M.E., Binder D.K.
