No. People do not die from Parkinson’s, rather they die with Parkinson’s. Complications, for example pneumonia caused by aspiration in connection with difficulty swallowing, can lead to death. Parkinson’s by itself does not directly cause people to die. With the treatment that is now available, life expectancy for someone with Parkinson’s is fairly normal and none of the medication that are used have any serious side effects that could cause death.
However, occasionally in people who are seriously disabled (usually those who have had Parkinson’s for many years), their general physical and mental condition can either cause or exacerbate other illnesses and so contribute to the final cause of death.
