A student asked me about something called "motor-neuron disorder" and looked quite surprised when I said I had never heard this term before. She said that Sarah Ferguson was an honorary chairperson (or something like this) of a foundation for the study of this "disorder." My guess was that this was not a particular disorder but a class of disorders all of which involve degeneration of motor pathways. Is this a term that is often used? If it is, does anyone know which disorders would be classified as "motor-neuron disorders"? Thank yo, Jeff -- Jeffry P. Ricker, Ph.D. Office Phone: (480) 423-6213 9000 E. Chaparral Rd.
