Question

autoimmune blockade of presynaptic neurotransmitter release is the pathogenesis of: eaton - lambert syndrome guillain - barre syndrome atropine myasthenia gravis botulinum

Explanation:

Eaton - Lambert syndrome is characterized by autoimmune blockade of presynaptic neurotransmitter release. Guillain - Barre syndrome is an immune - mediated polyradiculoneuropathy not mainly due to presynaptic neurotransmitter release blockade. Atropine is a drug, not a disease with this pathogenesis. Myasthenia gravis involves autoantibodies against postsynaptic acetyl - choline receptors. Botulinum is a toxin, not a disease with autoimmune presynaptic blockade as its pathogenesis.

Answer:

A. Eaton-Lambert syndrome
