The life expectancy for someone with Parkinson's disease is the same as for people who do not have the disease, according to the Parkinson's Disease Foundation. Although this is an incurable and progressive disease in which symptoms get worse, Parkinson's disease is not a fatal disease.
Based on a research study, the survival rate for patients who had this disease between 15 to 20 years was only a little lower when compared with people without the disease and of the same age, as stated by the Parkinson's Disease Foundation. Researchers also noted that the participants of this study had an average lifespan of approximately 77 years.
Parkinson's is a disease of the brain that affects the body's motor system. The symptoms of this disease include tremors, slow movement, and muscle rigidity, notes Mayo Clinic. Over time, the symptoms get worse and can lead to difficulty in walking, speaking and mental ability. It is usually in the advanced stages of Parkinson's disease in which there can be complications, such as aspiration and pulmonary embolism. However, these complications may not lead to a reduction in life expectancy.
