Hi,,
From what i recall..
pseudobalbar palsy refers to UMNL
while bulbar palsy refers to lower motor neuron disease
so u would have different cuzes and different clinical manifestations

thank u

Now if u suspect a facial nerve palsy in a patient and u want to judge is it upper or lower motor neuron lesion :
if it was a LMNL the whole face would be paralysed while in UMNL the upper half(frontalis muscle )would be able to contract cuz it has some extra supply

Hope this helps

Pseudobulbar palsy is bilateral impairment of the function of the lower cranial nerves 9, 10, 11 and 12 due to upper motor neuron lesion of the bulbar muscles from lesions of 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

Symptoms
* Dysphagia (difficulty in swallowing)
* Labile affect
* Dysarthria

Signs
* 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
