Spinal muscular atrophy was first reported by Guido Werdnig in 1891, when
he described "Two hereditary cases of progressive muscular atrophy
appearing as dystrophy, but on a neurotic
basis."1 A
year later, Professor Johann Hoffmann of the University of Heidelberg used the
term "spinale
muskelatrophie."2
These initial descriptions were the first to correlate the clinical findings
of these patients with the histological analysis that demonstrated a lack of
anterior horn cells with the normal number of motor neurons. Although
classification systems such as the one described by Byers and
Banker3 have been
developed to aid physicians in making a prognosis for these patients, spinal
muscular atrophy is an extremely heterogeneous condition in which clinical
manifestations as well as life span vary widely. The classification system of
Byers and Banker is the one that is most often used; however, neurologists
have used a slightly different nomenclature that is based primarily on . . . [Full Text of this Article]
