Acute inflammatory neuropathies require more urgent and aggressive management with intravenous immunoglobulin9 or plasmaphereis.10 In addition, respiratory function testing and hemodynamic monitoring are warranted. Note: this also drops protein levels in the blood (why the woman needs a protein-rich diet). Loss of sensation (including vibration, proprioception, temperature, and pinprick sensations) in distal extremities suggests peripheral neuropathy, as does a distal-to-proximal gradient of reflex elicitation. If you experience any of these changes in vision, you should contact your healthcare provider immediately or go directly to the hospital. By convention the deep tendon reflexes are graded as follows: 0 = no response; Dtr or deep tendon reflex is a test done on physical exam to evaluate specific nerve function.
