What causes Lambert Eaton myasthenic syndrome ?
What causes Lambert Eaton myasthenic syndrome? Lambert Eaton myasthenic syndrome is the result of an autoimmune process which causes a disruption of electrical impulses between nerve cells and muscle fibers. In cases where Lambert Eaton myasthenic syndrome appears in association with cancer, the cause may be that the bodys attempt to fight the cancer inadvertently causes it to attack nerve fiber endings, especially the voltage-gated calcium channels found there. The trigger for the cases not associated with cancer is unknown.
