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.

  • Progressive muscular atrophy

    Progressive muscular atrophy (PMA) is a rare subtype of amyotrophic lateral sclerosis (ALS) or motor neurone disease (MND) which affects only the lower motor neurones. PMA is thought to account for around 4% of all ALS/MND cases. This is in contrast to the most common form of ALS/MND, amyotrophic...
