A summary of the article is shown below:
BACKGROUND: Despite its negative impact on quality of life, fatigue in Parkinson’s disease (PD) remains an under-recognized issue and the underlying pathology is undetermined.OBJECTIVE: To contribute at understanding the pathogenesis of fatigue in a naturalistic cohort of cognitively intact PD patients.METHODS: In a Caucasian population of PD patients (n = 27), we evaluated to what extent fatigue (quantified as PFS-16 score) is associated with PD duration and with autonomic dysfunction, studied by both MIBG scintigraphy and autonomic nervous system testing. The latter included the head-up tilt test, Valsalva maneuver, deep breathing, and handgrip tests.RESULTS: PFS-16 score correlated with disease duration (R = 0.57, p = 0.002). Fatigue showed a clear correlation with deep breathing test (R = - 0.53, p = 0.004) but not with the MIBG H/M ratios.CONCLUSIONS: Our data are consistent with a multifactorial pathogenesis of fatigue and with effects of dopamine depletion in PD-related fatigue; on the other hand, our findings do not support a role for sympathetic denervation in PD-related fatigue.
