Exclusion Criteria

Related to Parkinson’s disease
- Diagnosis is unclear or a suspicion of other parkinsonian syndromes exists, such as secondary parkinsonism (caused by drugs, toxins, infectious agents, vascular disease, trauma, brain neoplasm), Parkinson-plus syndromes (e.g. multiple system atrophy, progressive supranuclear palsy) or heredodegenerative diseases.

- Presence of dyskinesias, motor fluctuations or loss of postural reflexes.
- Subjects with a history of non-response (according to both the clinician and the subject) to an adequate course of L-dopa or a dopamine agonist.
- Subjects for whom previous treatment with dopamine agonists needed to terminate because of induction of psychosis (i.e. hallucinations) and/or sleep attacks.
