Non-motor Symptoms (Depressive Symptoms) of Parkinson's Disease and Their Course Under Pramipexole Treatment

Study Overview
=================
Brief Summary
-----------------
The objective of this PMS study is the evaluation of depressive symptoms measured with Unified Parkinson's Disease Rating Scale (UPDRS) Part I (mentation, behavior and mood) and with Hospital Anxiety and Depression Scale Depression Subscore (HADS-D) under pramipexole treatment in early and advanced PD patients. In addition it will be investigated whether improvement of depressive symptoms is linked to improvement in motor function (UPDRS Part III). 250 patients diagnosed with Parkinson's disease (PD) will be investigated by 80 specialists (neurologists or neurologists/psychiatrists) across Austria. Pramipexole will be taken orally at an initial dosage of 0.375 mg/day (using a three times daily schedule independently of food intake) and can be titrated upwards, as required, at weekly intervals to a maximum total daily dose of 4,5 mg (TID) as per Summary of Product Characteristics (SPC).

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change From Baseline in Unified Parkinson's Disease Rating Scale (UPDRS) Part I (Mentation, Behaviour and Mood) | Rating scale scored from 0 (none) - 4 (severe). The UPDRS Part I (Mentation, Behaviour and Mood during the Past Week) consist of 4 items, each of them is scored from 0 (normal) to 4 (severe). Reduction in this score over time is interpreted as improvement. Total UPDRS part I score ranges from 0 = best score to 16 = worst score | Baseline and Final (visit 3) - Change from baseline (i.e. decrease of score) | 
| Change From Baseline in Hospital Anxiety and Depression Scale - HADS-D Depression Subscore | Depression Scale - 7 items scored for each individual question from 0 = best and 3 = worst. HADS is a self-assessment scale for the symptom severity of anxiety disorders and depression. It comprises of 14 items, thereof seven statements describe anxiety and seven statements depression. Each answer is rated on a four-point scale (0-3). All seven answers are summarized and calculated to a total score to the anxiety scale and to the depression scale with a maximum score of 21 points for each scale. | Baseline and Final (visit 3) - Change from baseline (i.e. decrease of score) | 
| Change From Baseline in Hospital Anxiety and Depression Scale - HADS-A Anxiety Subscore | Anxiety Scale - 7 items scored for each individual question from 0 = best and 3 = worst. HADS is a self-assessment scale for the symptom severity of anxiety disorders and depression. It comprises of 14 items, thereof seven statements describe anxiety and seven statements depression. Each answer is rated on a four-point scale (0-3). All seven answers are summarized and calculated to a total score to the anxiety scale and to the depression scale with a maximum score of 21 points for each scale. | Baseline and Final (visit 3) - Change from baseline (i.e. decrease of score) | 
| Change From Baseline in UPDRS Part III (Motor Examination) | 14 components rating scale with 27 items scored by 0 (none) - 4 (severe) | Baseline and Final (visit 3) - Change from baseline (i.e. decrease of score) |
