During the following decades, isolated evasions of this form and isolated cases of muscle atrophy of a different character were described. As a result of these works, Duchenne-Agap's muscular atrophy ceased to exist as a separate disease form, but was only a type of muscular atrophy, also observed in gliomatosis, amyotrophic lateral sclerosis, etc.</p>Kazan Medical archiveКазанский медицинский архив
