How is Parkinson's disease caused?

Parkinson's disease is mainly caused by the loss of dopaminergic neurons in substantia nigra, which is a clinical syndrome characterized by slow movement with limb stiffness and jitter.

Parkinson's disease is usually a hereditary disease caused by exposure to toxic chemicals. For example, herbicides or pesticides damage dopaminergic neurons, leading to the decrease of transmitters and inducing Parkinson's syndrome.

In addition, exposure to toxic substances can also lead to the damage of dopaminergic neurons in substantia nigra, which will lead to increased muscle tension and corresponding symptoms. At the same time, with the increase of age, neurons gradually degenerate. Include neurons in substantia nigra, which can also induce Parkinson's disease.
