Primary progressive aphasia, as a slowly progressive neurodegenerative disease with a clinical predominance of different speech and language disorders, is a promising model for a more detailed study of topographic distribution of language disorders. This review presents data on different clinical variants of primary progressive aphasia and the corresponding clinical and neuroanatomical correlates that have significantly expanded the modern understanding of the neural network language organization.</p></abstract><trans-abstract xml:lang="ru"><p>Речь является одной из высших корковых функций и представляет собой основной метод коммуникации, из-за чего сложно переоценить её значимость для полноценного функционирования человека в социуме. Первичная прогрессирующая афазия, будучи медленно развивающимся нейродегенеративным заболеванием с преобладанием в клинической картине разнообразных речевых нарушений, является перспективной моделью для более подробного исследования топографического распределения расстройств речи. В обзоре приводятся данные о различных клинических вариантах первичной прогрессирующей афазии, а также соответствующие им клинико-нейроанатомические корреляции, благодаря которым в значительной степени расширилось современное понимание нейросетевой организации речи.</p></trans-abstract><kwd-group xml:lang="en"><kwd>primary progressive aphasia</kwd><kwd>language</kwd><kwd>neurodegeneration</kwd><kwd>frontotemporal dementia</kwd><kwd>Alzheimer’s disease</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>первичная прогрессирующая афазия</kwd><kwd>речь</kwd><kwd>нейродегенерация</kwd><kwd>лобно-височная деменция</kwd><kwd>болезнь Альцгеймера</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap></funding-source><award-id>23-25-00483</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Gorno-Tempini M.L., Hillis A.E., Weintraub S. et al.
