Non-motor symptoms in parkinson’s disease

Abstract

Non-motor symptoms are very important for a better quality of life in patients with Parkinson’s disease (PD) but are not enough recognized and treated. The most common non-motor symptoms are pain, autonomic dysfunction, cognitive problems and dementia, depression, fatigue, apathy, sleep disturbances. Some of them precede motor symptoms and can be, also, very important in trying to recognize PD in an early phase. It appears that they are a major cause of disability. In this review the most often non-motor symptoms will be shown, especially cognitive problems and neuropsychiatric features.
