<prompt> All are true regarding G.B. syndrome, Except :Predominant motor involvementAbsence of myelocytosis in CSFResidual disability if treatment delayedSparing of bladder function  <response>: Ans. is c Residual disability if treatment is delayed. Ref. Harrison, 16e, p 2514, 2516 15e, p 2507.In Guillain-Bare syndrome 85 of the patients achieve a full functional recovery within several months to years.There is some confusion over choice d because bladder can be involved in G.B. syndrome but it is involved in only severe cases and the involvement is usually transient Moreover Harrison states if bladder dysfunction is prominent feature and comes early in the course, possibilities other than G.B. syndrome should be considered. So we can take the option d as true. Clinical feature of G.B. syndrome;Areflexic motor paralysis with or without sensory disturbance.Ascending paralysisLegs are more affected than armFacial nerve involvement in 50patientsLower cranial nerves are also frequently involvedDeep tendon reflexes usually disappear within few days of onset.CSF characteristically contain a high protein concentration with a normal cell count.
