Approach to the patient with early Parkinson disease: diagnosis and management.

This article presents an evidence‐based approach to the patient with newly diagnosed Parkinson disease (PD). It includes a discussion of the current understanding of the aetio‐pathogenesis of PD and of clinical features, both motor and non‐motor, that assist the clinician in making this diagnosis. An approach to the management of early stage PD is discussed, including emerging evidence of the benefits of physical exercise in this condition, and issues to consider in the selection of dopaminergic medication. The newly diagnosed patient with PD is often keen to know what the future holds for them, as they face this progressive neurodegenerative condition. While currently available medical therapies are symptomatic, rather than disease‐modifying, in nature, it is hoped that improved understanding of the aetio‐pathogenesis of PD will pave the way for future disease‐modifying therapies.
