What Are Some Signs of Bulbar ALS Progression?

Signs of bulbar amyotrophic lateral sclerosis progression include an increased shift to nasal pronunciation in everyday speech and growing difficulty regulating breathing in conversation, chewing and pronouncing words, the American Speech-Language-Hearing Association states. Bulbar ALS attacks motor neurons that regulate chewing and breath control, which gradually leads to atrophy of the muscles used in these activities. Eventually, the patient may become unable to swallow even semi-liquid foods and may need feeding through a tube inserted into the stomach.
