brain injury during perinatal or prenatal period	Cerebral palsy	0%
acquired inflammatory demyelinating polyradiculopathy of peripheral nerve; inc incidence w/ campylobacter jejuni or other antecedent respiratory/GI infections; immune mediated demyelination and axonal degeneration slowing nerve impulses;	Guillain Barre	0%
autoimmune peripheral nerve disorder associated w/ HLA-DR3; inefficient skeletal muscle neuromuscular transmission due to autoimmune ab against ach (nicotinic) postsynaptic receptor at neuromuscular junction leading to dec ach receptors; + Ach receptor ab, + MuSK (muscle specific tyrosine kinase) ab	Myasthenia gravis	0%
