Lambert Eaton myasthenic syndrome

Lambert-Eaton Syndrome

Overview

Type of disease: Rare conditions

Lambert Eaton myasthenic syndrome (LEMS) is a disorder of the neuromuscular junction. The neuromuscular junction is the site where nerve cells meet muscle cells and help activate the muscles. This syndrome occurs when antibodies interfere with electrical impulses between the nerve and muscle cells. It may be associated with other autoimmune diseases, or more commonly coincide with or precede a diagnosis of cancer such as small cell lung cancer. Symptoms may include muscle weakness, a tingling sensation in the affected areas, fatigue, and dry mouth. Treatment of a underlying disorder or cancer is the first priority of treatment.Source: Genetic and Rare Diseases Information Center (GARD), supported by ORDR-NCATS and NHGRI.
