Fig. 1: The life expectancy of people with Parkinson’s disease visualized.

The bars show the different life expectancies for men and women, per 10-year age band from 55 years and for PwP and people without PD. These data can also be used to derive the average years of life lost due to PD. Life expectancy estimates include the unweighted sex-specific average of Ishihara et al. (2007), Hobson et al. (2010) and Dommershuijsen et al. (2020)8,9,10. The results of Ishihara et al. (2007) are based on visual estimates from Figure 2 in that article. The individual studies showed variable estimates with wide confidence intervals. A formal meta-analysis remains necessary. The remaining life expectancy is dependent on individual characteristics and thus uncertainty regarding the individual prognosis should be emphasized when communicating this to patients. This visualisation needs patients’ testing before being implemented in clinical practice. PD Parkinson’s disease.
