Actually, 'amyotrophy' simply means muscle wasting without any implication
of the cause or pathophysiology.
(From Stedman's:
amyotrophy (G. a- priv. + mys, muscle, + trophy, nourishment). muscle wasting
or atrophy.)
The 'lateral sclerosis' part refers to the pathologic changes in the (lateral)
corticospinal tracts, which produce the upper motor neuron findings of the
disease.
