Objectives: To assess the association between clinical and socio-demographic features and anti-Parkinson drug (APD) treatment modifications in patients with PD and to describe neurologist and patient opinions regarding the need for changes in APD therapy. Methods: Subjects with PD with stable APD treatment over ≥3 months prior to baseline were enrolled and evaluated for socio-demographic data, disability, disease severity and neurologist and patient views on the need to modify APD treatment. Results: 775 Patients were included, 51% with Hoehn and Yahr (HY) stage 1-2 (early PD) and 49% with HY stage 2.5-4 (advanced PD). Neurologists modified APD treatment in 255 patients, 97 (25%) early PD and 158 (41%; p<0.0001) advanced PD. APD modification was strongly associated with a low educational level and UPDRS part IV score. The most common reasons behind the APD therapy changes among neurologists were presence/worsening of motor or non-motor symptoms (88% and 37% of subjects respectively). Out of 216 patients, 92% and 51% were willing to undergo APD changes to therapy because of the presence/worsening of motor or non-motor symptoms. Conclusions: Neurologist decision to change APD therapy and patients reasons for dissatisfaction with it can be prevalently attributed to the presence/worsening of motor symptoms and motor fluctuations in the advanced stages. Non-motor symptoms were considered more often by patients. The patient educational level played a key role in treatment decision.

Abstract
Objectives: To assess the association between clinical and socio-demographic features and anti-Parkinson drug (APD) treatment modifications in patients with PD and to describe neurologist and patient opinions regarding the need for changes in APD therapy.

Results: 775 Patients were included, 51% with Hoehn and Yahr (HY) stage 1-2 (early PD) and 49% with HY stage 2.5-4 (advanced PD). Neurologists modified APD treatment in 255 patients, 97 (25%) early PD and 158 (41%; p<0.0001) advanced PD.

The most common reasons behind the APD therapy changes among neurologists were presence/worsening of motor or non-motor symptoms (88% and 37% of subjects respectively). Out of 216 patients, 92% and 51% were willing to undergo APD changes to therapy because of the presence/worsening of motor or non-motor symptoms.
