[Quality of life in Parkinson's disease].

Assessing quality of life (QOL) is now essential for making clinical, economic, social, and political decisions. QOL is multi-dimensional, subjective, and context-dependent. It can encompass physical aspects of living, activities in daily life, communication with other people, spiritual existence, and more. Parkinson's disease is a chronic progressive disease that affects many organ-systems. Complete descriptions of QOL outcomes in patients with Parkinson's disease include both qualitative-narrative methods and quantitative scales. Assessing QOL in clinical practice can help clinicians improve patients' lives.
