title: Neuropsychiatric features of Parkinson's disease.
abstract: Parkinson's disease is a chronic, progressive, neurodegenerative condition that damages central nervous system pathways. In addition to the well-recognised motor features of the disease, patients commonly experience non-motor symptoms including neuropsychiatric complications. These symptoms may precede motor symptoms and have a very significant impact on quality of life for patients and their carers.
