In addition, PD frequently develops in already existing ET. The occurrence of PD in ET seems to be a problem of relevance, since the risk of PD is higher in patients with ET than that in the population. However, due to the lack of awareness about this nosological phenomenon among physicians, it can be difficult to formulate a diagnosis of PD that has developed in ET.</p><p>This paper gives an update on the clinical, epidemiological, pathogenetic, and neuroimaging characteristics of ET concurrent with PD. </p></abstract><trans-abstract xml:lang="ru"><p>В последние десятилетия появляются данные о взаимосвязи болезни Паркинсона (БП) и эссенциального тремора (ЭТ). Кроме того, зачастую БП развивается на фоне уже существующего ЭТ. Проблема возникновения БП на фоне ЭТ представляется актуальной, так как у пациентов с ЭТ риск развития БП выше, чем в популяции. Однако из-за недостаточной информированности врачей о данном нозологическом феномене сформулировать диагноз БП, развившейся на фоне ЭТ, бывает сложно.</p><p>Представлены современные данные о клинических, эпидемиологических, патогенетических и нейровизуализационных особенностях сочетания ЭТ и БП. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>болезнь Паркинсона</kwd><kwd>эссенциальный тремор</kwd><kwd>сочетание эссенциального тремора и болезни Паркинсона</kwd><kwd>«смешанный» фенотип</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Parkinson's disease</kwd><kwd>essential tremor</kwd><kwd>concurrence of essential tremor and Parkinson's disease</kwd><kwd>mixed phenotype</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">Critchley E.
