Parkinson's disease is a degenerative disease of the nervous system that has a very concealed onset and progresses very slowly, making the progression of this disease not rapid. Patients can generally take care of themselves for about three to five years, or even five to ten years, without having to worry too much about this disease. This disease primarily causes patients to experience obvious bradykinesia, mask-like faces, drooling, resting tremors, and increased muscle tone among other clinical manifestations, which can significantly distress patients. However, the progression of this disease is relatively slow, and the signs and symptoms on the left and right sides of the body are also asymmetric. After effective pharmacological treatments, such as commonly used levodopa and dopamine receptor agonists, patients' symptoms can usually be well controlled and the progression is slow. If the disease progresses very quickly, it could potentially be Parkinsonian syndrome.
