A person with progressive bulbar palsy lacks strength in the jaw, tongue, and facial muscles. Swallowing food becomes challenging, and they lose the ability to speak. Other symptoms are a weakness in the limbs and uncontrollable incidents of laughing or crying. Any affliction that interferes with the cranial nerve nuclei can cause this disease. It is considered a type of amyotrophic lateral sclerosis (ALS), and there is no cure. Life expectancy is about two years. Get to know the common causes of progressive bulbar palsy now.
