Lambert-Eaton Syndrome

Lambert-Eaton Syndrome (pronounced: lam-bert ee-ton sin-drome) is a rare autoimmune disorder that is characterized by muscle weakness. The syndrome is also known as Lambert-Eaton Myasthenic Syndrome (LEMS) and Lambert-Eaton Syndrome (LES).

Etymology

The syndrome is named after two physicians, Edward Lambert and Lee Eaton, who first described the condition in 1956.

Symptoms

The primary symptom of Lambert-Eaton Syndrome is muscle weakness, which typically affects the muscles of the legs before the arms, hands, and trunk. Other symptoms may include dry mouth, impotence in men, and changes in bowel and bladder function.

Causes

Lambert-Eaton Syndrome is caused by a disruption in the normal functioning of nerve cells. This disruption is often associated with certain types of cancer, particularly small cell lung cancer. However, in some cases, the cause of Lambert-Eaton Syndrome is unknown.

Diagnosis

Diagnosis of Lambert-Eaton Syndrome typically involves a physical examination, a review of symptoms, and certain tests, such as electromyography and a blood test to check for the presence of certain antibodies.

Treatment

Treatment for Lambert-Eaton Syndrome often involves addressing the underlying cause of the condition, such as treating the associated cancer. Medications may also be used to improve muscle strength and reduce symptoms.
