Fatigue as the presenting symptom of chronic inflammatory demyelinating polyneuropathy.

Different clinical presentations of chronic inflammatory demyelinating polyneuropathy (CIDP) have been described. Fatigue is generally considered to be a secondary sign and is not mentioned as a warning sign for the diagnosis. We present a patient with CIDP in whom fatigue remained the only symptom, hereby stressing the importance of adding this disease to the differential diagnosis of fatigue. Immunomodulatory treatment did not change the clinical course of the patient, but electrodiagnostic features improved substantially.
