Heredity is a cause of Parkinson’s disease, but it is not the determining factor. Parkinson’s disease is not a genetic disease and about 10% of people with Parkinson’s disease have a family history of the disease.
Parkinson’s disease is a neurodegenerative disease that is prevalent in middle-aged and older adults. The vast majority of patients have sporadic disease, and about 10% of patients with Parkinson’s disease have a family history of the disease, which suggests that there is a genetic predisposition, but heredity is not a determining factor in causing Parkinson’s disease.
The development of Parkinson’s disease is also associated with neurological aging, progressive reduction of dopaminergic neurons, and long-term exposure to industrial or agricultural toxins.
Once Parkinson’s disease is diagnosed, it needs to be treated as soon as possible. If left untreated for a long period of time, the patient’s symptoms will gradually worsen until he/she loses the ability to take care of himself/herself.
