Bulbar-paralytic form of progressive muscular dystrophy

The beginning of the study of progressive muscular atrophy dates back to the fifties of the last century, when Duesschenne and Agap described a certain type of muscular atrophy, which for a long time appeared as an independent disease (Duchenne-Agap's progressive muscular atrophy). 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.
