What are the symptoms of LEMS?

People with LEMS may experience:

  • Weakness in the muscles, especially in the arms and legs
  • Fatigue that gets worse with activity
  • Difficulty in climbing stairs or lifting heavy objects
  • Difficulties with eye movements, like keeping the eyes open
  • Dry mouth and changes in taste

What causes LEMS?

The exact cause of LEMS is not fully understood. It often happens when the body’s immune system produces antibodies that attack the connection between nerves and muscles. In some cases, it can be linked to certain types of cancer, especially small cell lung cancer.

How common is LEMS?

LEMS is very rare. It affects only a small number of people and is much less common than another condition called myasthenia gravis.

Who is more likely to get LEMS?

Several factors may increase the risk of developing LEMS:

  • Being an adult, as it mainly affects adults rather than children
  • Having a history of certain cancers, particularly small cell lung cancer

How can I treat LEMS?

While LEMS is not curable, there are treatments that can help manage the symptoms. These may include:

  • Medication to help improve muscle strength
  • Treatments aimed at managing any associated cancers
  • Physical therapy to help with muscle function and movement
