Fatigue is a recognized problem in Parkinson’s disease and
other clinical conditions. We characterized this symptom in 19
patients and 19 age- and sex-matched controls, using the
Multidimensional Fatigue Inventory (MFI) and the Geriatric
Depression Scale. Fatigue may be an independent symptom in
Parkinson’s disease, frequently associated with depression. Our
analysis showed the usefulness of the MFI in discriminating
between different dimensions of fatigue for a better therapeutic
approach.
