All are true regarding G.B. syndrome, Except :

Ans. is 'c' Residual disability if treatment is delayed. (Ref. Harrison, 16/e, p 2514, 2516 (15/e, 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 paralysis*Legs are more affected than arm*Facial nerve involvement in 50%patients*Lower cranial nerves are also frequently involved*Deep tendon reflexes usually disappear within few days of onset*.CSF characteristically contain a high protein concentration with a normal cell count*.
