Bulbar

Question:

What is bulbar myasthenia? how is it differed from the plain myasthenia? if there is a plain myasthenia.

thanks

Answer:

Patients with myasthenia gravis develop a range of symptoms. Some have only weakness of eye muscles (ocular myasthenia). Others have weakness only (or much more severely) of bulbar muscles. This term refers to weakness of muscles supplied by an area of the brain called the brain stem (or bulb). These muscles are those of the throat and face. Patients have speaking and swallowing difficulties.

At present it is not known why some patients have particular involvement of these muscles.
