Parkinson's disease is a degenerative disease of the nervous system that currently cannot be cured in medicine. It is important to choose the right treatment plan to avoid being deceived. Parkinson's disease is mainly caused by the irreversible death of dopaminergic neurons in the substantia nigra, resulting in clinical manifestations such as bradykinesia, muscular rigidity, and tremors in limbs. Other non-motor symptoms include reduced sense of smell, constipation, anxiety, depression, and orthostatic hypotension. Treatment primarily focuses on symptomatic relief, and it is not expected to achieve complete remission. Commonly used medications include levodopa, anticholinergics, and activators of levodopa and dopamine receptors. Symptoms in patients usually progressively worsen, and curing the disease is very difficult.
