“Like a polio ward from the 1950s” is how Guy McKhann, M.D., a neurology specialist at John Hopkins School of Medicine, describes a ward of Beijing Hospital that he visited on a trip to China in 1986. Dozens of paralyzed children---some attached to respirators to assist their breathing--filled the ward to overflowing. The chinese doctors thought the children had Guillain-Barre syndrome (GBS), a rare paralytic condition, but Dr. McKhann wasn’t convinced. There were simply too many stricken children for the illness to be the rate Guillain-Barre syndrome. Was it polio--as some of the Beijing staff feared? Or was it another illness, perhaps one that had not yet been discovered? Guillain-Barre syndrome is a relatively rare paralytic condition that strikes after a viral infection or an immunization. There is no cure, but usually the paralysis slowly disappears, and lost sensation slowly returns as the body repairs itself. In classic Guillain-Barre, patients can neither feel sensations nor move their muscles.

Is the paralytic illness that affected the chinese children a demyelinating condition? Why or why not?
