This symptom is characterized by specific speech disorders. The article presents the etiopathogenic features of PPA, systematizes the clinical criteria for its diagnosis, and describes the modern neuroimaging characteristics of different types of PPA. The proposed PPA severity point scale allows clinicians to record the very early manifestations of aphasia. Modified scales, such as the Frontal Behavioral Inventory (FBI-mod) and the Clinical Dementia Rating (CDR), are also important for specifying the type of PPA.</p></abstract><trans-abstract xml:lang="ru"><p>Первичная прогрессирующая афазия (ППА) – гетерогенная группа нейродегенеративных заболеваний, относящихся к фокальным дегенерациям головного мозга и преимущественно проявляющихся постепенной утратой речевых функций. Для данного симптома характерны специфические речевые нарушения. Представлены этиопатогенические особенности ППА, систематизированы клинические критерии ее диагностики, описаны современные нейровизуализационные характеристики разных видов ППА. Предлагаемая балльная шкала тяжести симптомов ППА позволяет фиксировать уже начальные проявления афазии. Важное значение имеют также модифицированные шкалы для уточнения формы ППА, такие как Frontal Behavioral Inventory (FBI-mod) и Clinical Dementia Rating (CDR).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром первичной прогрессирующей афазии</kwd><kwd>деменция</kwd><kwd>тау-протеин</kwd><kwd>бета-амилоид</kwd><kwd>магнитно-резонансная томография с морфометрией</kwd></kwd-group><kwd-group xml:lang="en"><kwd>primary progressive aphasia</kwd><kwd>dementia</kwd><kwd>tau protein</kwd><kwd>beta amyloid</kwd><kwd>magnetic resonance imaging with morphometry</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">Mesulam MM.
