DM neuropathy v CIDP

Use rules

1.  With proximal weakness and distal weakness, in absence of genetic disorder, CIDP is overwhelmingly more likely; diabetic is usually not proximal\

2.  Diabetic is sensory, CIDP is motor more

3.  Diabetic is insidious, CIDP is aggressive

4.  Distal/proximal gradient reflex loss is more common in DM

5.  Objective response to immunomodulation is much more common in CIDP

 

(Obvious but still useful)
