Is Parkinson’s Disease hereditary?
Although most Parkinson’s disease develop idiopathic Parkinson’s disease where there is no clear genetic or familial predisposition but in around 5% of cases there may be some genetic influence.
Transcript
I have seen that most patients with Parkinson's disease develop what we call Idiopathic Parkinson's disease. That means that it comes really quite out of the blue without a family history or without a clear genetic precipitant. There are a small number of patients, perhaps five percent or so, who may have a very clear genetic cause where other members in the family may have a genetic cause for it. However, we do know that our genes interplay in very complex ways with the environment to predispose most of us who get Parkinson's disease to develop it. So although it may not be strictly inherited, for most patients genes do play an important part.
