What Is Bulbar Weakness?
Bulbar weakness is weakness of the muscles controlled by the brainstem that are responsible for speaking, swallowing, chewing, and managing saliva. It develops when the nerves or muscles involved in these functions are damaged by neurological diseases or other medical conditions.
Bulbar weakness can significantly affect nutrition, communication, and airway protection if not properly managed.
