Although 30% of people with Parkinson’s disease do not experience tremors throughout the course of their disease, people with Parkinson’s disease invariably experience bradykinesia, which often starts with one limb and gradually progresses to bilateral, such as poor hand movement, foot dragging, difficulty turning, lack of arm swinging, and small writing. This type of delayed movement occurs mainly when changing position or at the beginning of movement, and is manifested by difficulty in starting, walking forward, and inability to stop in time. If there is a combination of tremor, muscle stiffness, or unstable balance, this is a very typical manifestation of Parkinson’s disease. If the patient does not have typical resting tremor, or only has partial motor symptoms, or only has preclinical symptoms of Parkinson’s disease such as smell disturbance, depressive symptoms, sleep difficulties, constipation, restless legs syndrome, etc., the diagnosis is often not made in a timely and correct manner. Many patients and their families do not know enough about the disease and often do not come to the clinic until the disease is very serious, losing the best time for treatment. There is no curative treatment for Parkinson’s disease, but many palliative treatment drugs are effective for early and mid-stage patients, such as dopa replacement agents, non-ergot dope-ergic receptor agonists, COMT inhibitors, and neuroprotective agents. The most important treatment principle for Parkinson’s disease is individualized treatment, which needs to be given according to different conditions, and each person’s condition is different and the treatment plan may be completely different.
