What is bulbar paralysis?

Progressive bulbar palsy involves the brain stem. The brain stem is the part of the brain needed for swallowing, speaking, chewing, and other functions. Signs and symptoms of progressive bulbar palsy include difficulty swallowing, weak jaw and facial muscles, progressive loss of speech, and weakening of the tongue.

What is a bulbar stroke?

Bulbar palsy is a set of conditions that can occur due to damage to the lower cranial nerves. Clinical features of bulbar palsy range from difficulty swallowing and a lack of a gag reflex to inability to articulate words and excessive drooling. Bulbar palsy is most commonly caused by a brainstem stroke or tumor.

Why is it called bulbar paralysis?

Description. Bulbar relates to the medulla. Bulbar palsy is the result of diseases affecting the lower cranial nerves (VII-XII). A speech deficit occurs due to paralysis or weakness of the muscles of articulation which are supplied by these cranial nerves.

What is bulbar function?

Bulbar weakness (or bulbar palsy) refers to bilateral impairment of function of the lower cranial nerves IX, X, XI and XII, which occurs due to lower motor neuron lesion either at nuclear or fascicular level in the medulla or from bilateral lesions of the lower cranial nerves outside the brain-stem.

What are bulbar nerves?

In nervous system disease: Bulbar nerves. (In this context, the term bulbar refers to the medulla oblongata, which looks like a swelling, or bulb, at the top of the spinal cord.) Damage to the 9th through 12th cranial nerves, the bulbar nerves, causes impairment of swallowing and speech and…

What is bulbar brain?

What is the medical term for progressive bulbar palsy?

Progressive bulbar palsy ( PBP) is a medical condition. It belongs to a group of disorders known as motor neuron diseases. PBP is a disease that attacks the nerves supplying the bulbar muscles. These disorders are characterized by the degeneration of motor neurons in the cerebral cortex, spinal cord, brain stem, and pyramidal tracts.

What is the life expectancy of progressive bulbar palsy?

Epidemiology. Progressive Bulbar Palsy is slow in onset, with symptoms starting in most patients around 50–70 years of age. PBP has a life expectancy typically between 6 months and 3 years from onset of first symptoms. It is subtype of the Motor Neuron Diseases (MND) accounting for around 1 in 4 cases.

Who was the first person to discover progressive bulbar palsy?

The disease was first recognized by French neurologist, Guillaume Duchenne in 1860 and termed, “labioglossolaryngeal paralysis”. In 1859, Wachsmuth changed the name to progressive bulbar palsy.

Are there any treatments for progressive bulbar palsy?

PBP is aggressive and relentless, and there were no treatments for the disease as of 2005. However, early detection of PBP is the optimal scenario in which doctors can map out a plan for management of the disease. This typically involves symptomatic treatments that are frequently used in many lower motor disorders.
