Motor neuron diseases

In motor neuron disease, nerve cells called motor neurons progressively lose function, causing the muscles they control to become weak and then nonfunctional.

Ion channel diseases

Diseases associated with defects in proteins called ion channels typically are marked by muscular weakness, absent muscle tone, or episodic muscle paralysis.

Neuromuscular junction diseases

Neuromuscular junction disorders result from the destruction, malfunction or absence of one or more key proteins involved in the transmission of signals between muscles and nerves.

Peripheral nerve diseases

In peripheral nerve diseases, the motor and sensory nerves that connect the brain and spinal cord to the rest of the body are affected, causing impaired sensations, movement or other functions.

Because of continuing advances in research and medicine, this list is meant to serve as a guide. To find out if MDA covers a disease that is not listed here, contact the MDA Resource Center by email at or by phone at 1-833-ASK-MDA1 (1-833-275-6321).
