Motor Neuron Disease

Motor Neuron Disease refers to 5 neurological disorders which cause cells that control voluntary muscle activity (e.g., use of the arms and legs, speaking, swallowing, etc.) to degenerate resulting in increasing disability and, eventual death. Baseball legend, Lou Gehrig, suffered from ALS (Amyotropic Lateral Sclerosis) one form of the disease; Stephen Hawking suffers from a different form of the disease.
