Question

Use your favorite resource to verify your answers.

  • Peripheral neuropathy:
    Where does it start and why, after X body parts, what is affected next (and why)?
  • Review and write down:
    • Brown-Séquard pattern.
    • Syringomyelia pattern.
  • Spaced repetition recall
    What is affected in:
    • Hemispheric stroke (e.g., R MCA stroke)?
    • Brainstem stroke (e.g., L vertebral artery)?

Sensory syndromes

In the above figures, the blue shading indicates hypalgesia (loss of pain and temperature sensation) and the arrows indicate limbs with significant accompanying weakness. In the Brown-Séquard syndrome (hemisection of the cord, top row, right), there is often diminished tactile sensation on the side of weakness and opposite the side with hypalgesia.
