Bulbar and Pseudobulbar Palsy

NICE has issued rapid update guidelines in relation to many of these. This guidance is changing frequently. Synonyms: 'bulbar palsy' - lower motor neurone dysarthria, neuromuscular dysarthria, atrophic bulbar paralysis; 'pseudobulbar palsy' - upper motor neurone dysarthria, spastic dysarthria.

Speaking is a voluntary task which is taken for granted but is a highly specialised activity. In order to speak, the following parts of the oral cavity need to be used:.

Along with this, controlled expiration is required, so that air can be released at the appropriate speed and in appropriate amounts. The above structures required for speech are controlled by the nervous system. Corticobulbar tracts from both of the motor cortices send signals down to the nuclei of the following nerves:. The motor aspects of speech, like other movements, are also influenced by the extrapyramidal system via the basal ganglia and the cerebellum.

There is ongoing research into which areas of the cortex are involved in speech and especially in recovery of speech after a stroke. Bulbar relates to the medulla. A speech deficit occurs due to paralysis or weakness of the muscles of articulation which are supplied by these cranial nerves. The causes of this are broadly divided into:. Importantly, these lesions do not affect speech in isolation. The bulbar nerves also innervate muscles involved in swallowing and facial muscles.

Bulbar palsy is sometimes also classified as non-progressive or progressive. Non-progressive bulbar palsy is an uncommon condition of uncertain aetiology and there are few reports of it in the literature. Genetic abnormalities have been identified in some cases presenting in childhood. Brown-Vialetto-Van Laere and Fazio-Londe syndromes are the most recent childhood forms of progressive bulbar palsy to be genetically defined.

If the pathology progresses then speech becomes slurred and eventually becomes indistinct. There may also be neurological deficits in the limbs - eg, flaccid tone, weakness with fasciculations. Pseudobulbar palsy results from disease of the corticobulbar tracts. Bilateral tract damage must occur for clinically evident disease as the muscles are bilaterally innervated.

There may also be neurological deficits in the limb - eg, increased tone, enhanced reflexes and weakness. New developments in technology have led to the use of neurophysiological investigations to assess various aspects of speech dysfunction. Other tests will depend on the suspected underlying cause but will involve routine blood tests, imaging of the brain and brainstem either CT scan or MRI and electromyography.

Progressive Bulbar Palsy

Request An Appointment. Refer a Patient. Progressive bulbar palsy is a motor neuron disorder that involves the lower motor neurons. These neurons conduct messages from the brain stem and spinal cord to the brain. Initially, patients with progressive bulbar palsy only have muscle weakness that affects speech and swallowing. However, this condition can often progress to amyotrophic lateral sclerosis or ALS. Sometimes individuals with this condition also have outbursts of laughing or crying, which is called emotional lability.

Pseudobulbar palsy is a syndrome about which little is known in spite of the fact that it not uncommonly follows cerebral vascular accidents and other forms of neurologic disease. It is our purpose, therefore, to present an anatomic and physiologic analysis of this condition. Magnus 1 first reported a case in which there were features characteristic of pseudobulbar palsy following multiple apoplectic attacks; he discussed the postmortem observations. Jolly 2 described a patient with multiple sclerosis and "progressive bulbar paralysis" whose bulbar nuclei were normal at autopsy; Barlow 3 emphasized the relation of bilateral cortical lesions to the syndrome. Ross 4 reviewed cases from an anatomic-functional point of view, and Oppenheim and Siemerling 5 differentiated pseudobulbar from true bulbar palsy.

Written and peer-reviewed by physicians—but use at your own risk. Read our disclaimer. Any condition which disrupts or damages the cranial nerve nuclei or corticobulbar tracts can cause bulbar or pseudobulbar palsy e.
