I just wanted to know if Parkinson's disease could be passed on over time to other siblings in my family. I have seven brothers and three sisters. I already lost two brothers to different health issues and my father passed away from Parkinson's disease. My mother passed away due to her age and health.

My hubs son has Parkinson's but no one else in the family tree has ever had it on either side of the family. Johns Hopkins says 10-20% are gene related. The other 80-90% are unknown.

I asked my mother’s neurologist about Parkinson’s disease being hereditary because Mom and her brother had it. He said that it can run in families but that I shouldn’t worry about it.

You can always do genetic testing for specific issues. My husband’s oncologist explained to him that some people want to do genetic testing so they can tell their children if a gene is present that could be passed down to them.

Is Parkinson's disease hereditary?

Like many other diseases, Parkinson's is a result of a complex interaction between genes and environmental factors. In a small number of people (up to 10%), Parkinson's is inherited and can affect multiple family members. Their children may have a higher risk of developing Parkinson's.

Who is most likely to inherit Parkinson's?

People who have Parkinson's at a younger age are more likely to have a genetic link. A change in the LRRK2 gene known as G2019S is probably the most common genetic change linked to Parkinson's.

Does Parkinson's run in the family?

A number of genetic factors have been shown to increase a person's risk of developing Parkinson's disease, although exactly how these make some people more susceptible to the condition is unclear. Parkinson's disease can run in families as a result of faulty genes being passed to a child by their parents.
