Background: Mild parkinsonian signs (MPS) are frequent in the elderly population and associated with the presence of risk markers for Parkinson's disease (PD). Both MPS and non-motor signs may be present in prodromal PD and may significantly impair quality of life (QoL). Objective: To disentangle the contribution of motor impairment and extra-motor manifestations to QoL in subjects with MPS (n=63), manifest PD (n=69), disorders with motor symptoms due to non-neurodegenerative diseases (n=213) and healthy controls (n=258). Methods: Subjects with MPS, healthy controls, disease controls (patients with motor impairment due to, eg, arthrosis and spondylosis), and PD patients (total n=603) were selected from a large epidemiological longitudinal study, the EPIPARK cohort. Motor function was determined using the UPDRSIII protocol, and information on depressive symptoms, anxiety, sleep, and QoL was assessed via rating scales and data were analyzed. Results: Depressive symptoms, anxiety, and sleep problems were equally frequent in the MPS group and controls. Health-related QoL was slightly reduced in the MPS group. Motor impairment and its extent was comparable between the MPS group and disease controls (UPDRSIII 5-6 points). Higher motor dysfunction was associated with lower QoL. Depressive symptoms, but not anxiety and daytime sleepiness, was significant predictors of general QoL, independent of motor function. Conclusions: Quality of life is slightly decreased in an elderly population with MPS. QoL is associated with severity of motor impairment but also with non-motor aspects, ie, depressive symptoms. Follow-up studies in large cohorts are warranted to determine the natural course of MPS and its impact on QoL.
