MND (motor neurone disease ) vs MMN (multifocal motor neuropathy )
MND= Mixed upper and lower motor neurone signs affecting multiple sites and cranial …no sensory signs …nerve study will not show block
MMN = Only lower motor neurone signs , commonly affecting one limb…no sensory signs…nerve study will show block
Any demyelinating neuroopathy ( chronic or acute like GB ) will show mixed lower motor neurone and sensory loss
