Tongue Wasting

  • Look For

  • Decreased mass of the tongue, unilaterally or bilaterally.
  • Causes of Tongue Wasting

  • Motor neuron disease
  • Hypoglossal (XII) nerve lesion - tumour, trauma, infarct, haemorrhage, demyelination, bulbar palsy
  • Interpretation

  • Unilateral wasting - suggestive of a lower motor neuron, involving the hypoglossal nerve (XII) or medullary hypoglossal nucleus
  • Bilateral wasting - suggestive of motor neuron disease, Guillain Barre or neurosyphilis

Tongue Fasciculations

  • Look For

  • Spontaneous localised muscle contraction and relaxation. May be associated with dysarthria or dysphagia.
  • Causes of Tongue Fasciculations

  • Motor neuron disease
  • Hypoglossal (XII) nerve lesion - tumour, trauma, infarct, haemorrhage, demyelination, bulbar palsy
  • Interpretation

  • Unilateral fasciculations - suggestive of a lower motor neuron lesion, involving the hypoglossal nerve (XII) or medullary hypoglossal nucleus
