Q

how can small cell lung cancer cause Lamber-eaton myasthenic syndrome ?

A

due to antibodies against small cell lung cancer which target and damage voltage gated calcium chennels on presynaptic terminals of motor neurones leading to weakness in proximal muscles. Can also affect intraocular, levator and pharyngeal muscles causing diplopia, ptosis, slurred speech and dysphagia

may also have dry mouth, blurred vision, impotence, dizziness due to autonomic dysfunction
