A member asked:

Is there a test to distinguish between lems and myasthenia gravis?

Yes. Called EMG.: The test is an electromyelogram, EMG for short. It stimulates muscles and nerves with small needle-like receptors and detects their activity. Myaesthenia gravis is known to produce less activity from nerves with repetitive stimulation while LEMS does the opposite, the neurons strengthen their stimulation on muscle with repetitive stimuli.
