Autoimmune disease characterized by muscle weakness usually affecting ocular and oropharyngeal muscles due to an autoimmune attack against components of the neuromuscular junction (e.g., the nicotinic acetylcholine receptor).
Note: This disease may be idiopathic, paraneoplastic [thymic tumor or lung (Lambert–Eaton myasthenic syndrome) tumor, etc.], or drug-induced (e.g., D-penicillamine).
