Infantile progressive bulbar palsy is progressive bulbar palsy in children. Blood to the bulbar conjunctiva is primarily derived from the ophthalmic artery. Neurotoxic symptoms (ptosis, ophthalmoplegia, bulbar paralysis, and peripheral muscular weakness) developed in 85%. In older patients, bulbar or pseudobulbar symptoms and spasticity predominate. Progressive bulbar palsy symptoms can include progressive difficulty with talking and swallowing. Depending on the site of paralysis, paralytic poliomyelitis is classified as spinal, bulbar, or bulbospinal. Progressive bulbar palsy (PBP) is a disease that attacks the nerves supplying the bulbar muscles. Deep tendon reflexes are usually decreased or absent, and ophthalmoplegia and bulbar palsy can occur. Isolated bulbar ALS can involve upper or lower motor neurons. In the 1940s tonsillectomy became controversial as several studies linked it to bulbar poliomyelitis. In 1859, Wachsmuth changed the name to progressive bulbar palsy. Spinal and bulbar symptoms tend to be mild or absent at the beginning. Accordingly, AOB mitral cells show clearly different firing patterns compared to other bulbar projection neurons. Examples include flail arm syndrome, flail leg syndrome, and isolated bulbar ALS. PBP is a disease that attacks the nerves supplying the bulbar muscles.
