Practical differential diagnosis of PSP and Parkinson’s disease (PD) presents significant challenge, especially in onset of the disease. We report an atypical case of PSP characterized by symmetric levodopa-resistant parkinsonian syndrome, early postural instability, supranuclear oculomotor disorders (vertical gaze palsy), MR signs of midbrain atrophy, and a number of overlapping clinical symptoms similar with the manifestations of PD. A detailed algorithm of differential diagnosis of PSP and PD as well as a more adequate diagnostic formulation are proposed for this and similar cases of neurodegenerative pathology.</p></abstract><trans-abstract xml:lang="ru"><p>Прогрессирующий надъядерный паралич (ПНП) – тяжелое нейродегенеративное заболевание позднего возраста, характеризующееся выраженным клиническим полиморфизмом и существованием различных фенотипов. Дифференциальная диагностика ПНП и болезни Паркинсона (БП) на практике вызывает значительные сложности, особенно в дебюте заболевания. В статье представлено наблюдение атипичного случая ПНП, характеризующегося симметричным леводопа-резистентным синдромом паркинсонизма, ранними постуральными расстройствами и надъядерными глазодвигательными нарушениями (парез вертикального взора), МРТ-признаками атрофии среднего мозга, а также рядом сочетанных клинических симптомов, сходных с проявлениями БП. Детализируется алгоритм дифференциальной диагностики ПНП и БП, предложена наиболее адекватная формулировка диагноза для этого и сходных случаев нейродегенеративной патологии.</p></trans-abstract><kwd-group xml:lang="en"><kwd>parkinsonism</kwd><kwd>progressive supranuclear palsy</kwd><kwd>Parkinson’s diseas</kwd><kwd>differential diagnosis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>паркинсонизм</kwd><kwd>прогрессирующий надъядерный паралич</kwd><kwd>болезнь Паркинсона</kwd><kwd>дифференциальная диагностика</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ivanova-Smolenskaja I.A., Markova E.D., Illarioshkin S.N., Nikol’skaja N.N.
