Pseudobulbar palsy is bilateral impairment of the function of the lower cranial nerves 9, 10, 11 and 12 which control the muscles of eating, swallowing and talking. It is the result of an upper motor neuron lesion to the corticobulbar pathways in the pyramidal tract.
Causes
* Vascular causes: Bilateral hemisphere infarction
* Degenerative disorders: motor neuron disease
* Inflammatory disorders: Multiple sclerosis
* Malignancy: High brain stem tumors
ymptoms
These include:
* Dysphagia (difficulty in swallowing)
* Labile affect[cite journal |author=McCormick WE, Lee JH |title=Pseudobulbar palsy caused by a large petroclival meningioma: report of two cases |journal=Skull Base |volume=12 |issue=2 |pages=67–71 |year=2002 |month=May |pmid=17167648 |pmc=1656925 |doi= |url=] ]
* Dysarthriaigns
These include:
* Speech is slow, thick and indistinct
* Gag reflex is normal or exaggerated
* Tongue is small, stiff and spastic
* Jaw jerk is brisk
* There may be upper motor neurone lesion of the limbs.
Bulbar palsy is a similar disorder but is caused by lower motor neurone lesions

* Corticobulbar tract
* Bulbar palsy
