Palsy caused by degeneration of the nuclear cells of the lower cranial nerves. This causes progressive muscular paralysis.
Bulbar palsy refers to the weakness of the muscles responsible for speech and swallowing, leading to symptoms such as slurred speech, hoarseness, difficulty in swallowing, and a risk of choking on food and beverages. This condition can arise due to damage to the nerve supply of the muscles, as observed in motor neuron disease, or as a result of muscular dystrophy, which affects the muscles themselves.
