Short review: Neuropsychiatric features of Parkinson’s disease

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.
