Parkinson's disease is mainly divided into two types. One type is familial Parkinson's disease, which definitely has a clear genetic predisposition. This disease is caused by mutations in some genes that lead to disruptions in some internal environments and the accumulation of abnormal proteins, eventually causing the death of neurons. Since the disease is caused by genetic mutations, there is definitely a certain genetic predisposition, and reproductive counseling is necessary to prevent the birth of offspring with Parkinson's disease. Moreover, most cases of Parkinson's disease are sporadic, and these diseases may be related to acquired factors, such as long-term mental stress, excessive pressure, brain trauma, or cerebrovascular diseases in patients, which can all lead to Parkinson's disease. This type of disease is definitely not inherited, so there is no need to worry too much.
