Lambert-Eaton Myasthenic Syndrome (LEMS) is a presynaptic NMJ disorder driven by anti-VGCC P/Q-type IgG antibodies reducing voltage-gated calcium channel density on motor nerve terminals, impairing acetylcholine vesicle fusion; 60% paraneoplastic (SCLC, thymoma), 40% autoimmune. Complement C3/C4 activation at presynaptic membrane, NF-kB/IL-6 immune loop, CD4+ Th helper; clinical: proximal limb weakness (legs > arms, worse initially improving with repetition = post-tetanic potentiation — key distinguishing feature from MG), autonomic dysfunction (dry mouth, constipation, erectile dysfunction), hyporeflexia; diagnosis: VGCC IgG serology, incremental EMG response at high frequency.
Sea moss fucoidan suppresses NF-kB and complement; selenium provides neural GPx antioxidant; omega-3 DHA supports presynaptic membrane phospholipids and resolvin D1 anti-inflammatory; zinc supports NMJ metalloenzymes. Read the full guide at Sea Moss for Lambert-Eaton Myasthenic Syndrome.
