The term motor neuron disease was introduced by Brain (1962) in recognition of the relationship between progressive muscular atrophy, amyotrophic lateral sclerosis, and progressive bulbar palsy, as shown by the differing patterns of involvement of upper and lower motor neurons and muscle wasting in these syndromes (Swash, 2000; Swash & Desai, 2000).
