Residual fatigue is independent of antecedent events and disease severity in Guillain-Barré syndrome.

The occurrence of severe fatigue after Guillain-Barré syndrome (GBS), and its relation with disease course, clinical characteristics, and antecedent infections was studied in 100 GBS patients. Severe fatigue, expressed as a mean Fatigue Severity Scale (FSS) score of 5.0 or more, was present in 60% of all patients. It was more frequently present in females and in patients over 50 years (p < 0.01). There was no significant relationship between fatigue severity and the level of functional disability at nadir, antecedent events or infections, clinical variables, and time to follow-up after GBS.
