Заболевание проявлялось в виде нарушений речи и письма, резкого расстройства трудовых навыков с сохранением самообслуживания и ориентации, аффективных колебаний, в связи с чем предполагалась диагностика когнитивных функций и психопатологических изменений, а также проведение инструментального исследования. Проведена дифференциальная диагностика с заболеваниями психического спектра, различными нейродегенеративными заболеваниями, сосудистым поражением головного мозга. Однако характер проявления заболевания, а также имеющиеся особенности нарушений когнитивных функций и речевых нарушений позволили предположить логопенический вариант синдрома первично прогрессирующей афазии (ППА), а наличие общего когнитивного снижения и прогрессирование заболевания в короткие сроки — болезнь Альцгеймера с атипичным началом.</p></abstract><trans-abstract xml:lang="en"><p>A description of a clinical case of the logopenic form of the syndrome of primary progressive aphasia in the onset of Alzheimer’s disease is presented.

However, the nature, as well as the existing features of cognitive impairment and speech impairment of the manifestation of the disease, suggested a logopenic warrant of the PPA syndrome, and the presence of a general cognitive decline and disease progression in a short time was Alzheimer’s disease with an atypical onset.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>деменция</kwd><kwd>первично прогрессирующая афазия</kwd><kwd>логопенический вариант первично прогрессирующей афазии</kwd><kwd>псевдодеменция</kwd><kwd>меланхолическая деменция</kwd><kwd>когнитивные нарушения</kwd><kwd>болезнь Альцгеймера</kwd><kwd>депрессия</kwd><kwd>афазия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dementia</kwd><kwd>primary progressive aphasia</kwd><kwd>logopenic variant of primary progressive aphasia</kwd><kwd>pseudodementia</kwd><kwd>melancholic dementia</kwd><kwd>cognitive impairment</kwd><kwd>Alzheimer's disease</kwd><kwd>depression</kwd><kwd>aphasia</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">Литвиненко И.В., Колмакова К.А., Емелин А.Ю., Лобзин В.Ю.
