MRCP revision battle 10.4: Pseudobulbar palsy

Pseudobulbar palsy is a UMN palsy of the muscles affecting eating, swallowing and talking above the midpons.

Signs are:
  • spastic tongue
  • brisk jaw jerk
  • emotional incontinence
  • 'Donald Duck' voice.

Causes include:
  • MS
  • MND
  • PD
  • stroke
  • high brain stem tumour

Just one more skirmish with neurology to go today, in the form of multifocal motor neuropathy.
