Motor neuron disease: Diseases characterized by a selective degeneration of the motor neurons of the spinal cord, brainstem, or motor cortex. Clinical subtypes are distinguished by the major site of degeneration. In AMYOTROPHIC LATERAL SCLEROSIS there is involvement of upper, lower, and brainstem motor neurons. In progressive muscular atrophy and related syndromes (see MUSCULAR ATROPHY, SPINAL) the motor neurons in the spinal cord are primarily affected. With progressive bulbar palsy (BULBAR PALSY, PROGRESSIVE), the initial degeneration occurs in the brainstem. In primary lateral sclerosis, the cortical neurons are affected in isolation. (Adams et al., Principles of Neurology, 6th ed, p1089).

Motor neuron disease is listed as a "rare disease" by the Office of
Rare Diseases (ORD) of the National Institutes of Health
(NIH). This means that Motor neuron disease, or a subtype of Motor neuron disease,
affects less than 200,000 people in the US population.

Motor neuron diseases (MNDs) are progressive, degenerative disorders that affect nerves in the upper or lower parts of the body. Some of the diseases are inherited, while others may be acquired. Common MNDs include amyotrophic lateral sclerosis (ALS), progressive muscular atrophy, and postpolio syndrome. (Source: excerpt from NINDS Motor Neuron Diseases Information Page: NINDS)
