Lambert-Eaton Myasthenic Syndrome Fund

Lambert Eaton Myasthenic Syndrome (LEMS) is a rare autoimmune 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 such as vitiligo or may 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.
