Neurological Differential Diagnosis

Following neurological examination, a you need to come up with a differential diagnosis

All you need to do is summarize your findings, and then decide if the findings are consistent with lower motor neurone signs or upper motor neurone signs - see table below.

Add in what you find in the sensory examination. You do NOT need to know the diagnosis

You will be taught lists of possible diagnoses in the Year 5 Neurology attachment

However, it is essential that you can perform a complete neurological examination in Year 3

Upper Motor neurone

  • Increased tone
  • Reduced power (weakness)
  • Brisk reflexes
  • Normal muscle bulk
  • Lesion in brain or spinal cord

Lower Motor neurone

  • Reduced tone (flaccidity)
  • Reduced power (weakness)
  • Reduced or absent reflexes
  • Wasting and atrophy
  • Lesion of anterior horn cell body or below (peripheral nerve)
