The core treatment for Parkinson's disease currently is pharmacotherapy, with surgical treatment serving as a supplement. Additionally, physical rehabilitation and psychological therapy are also recommended. The most effective drugs against Parkinson's at present include Levodopa, or compound Levodopa preparations. Other treatments include dopamine receptor agonists, monoamine oxidase inhibitors, amantadine, anticholinergic drugs, and catechol-O-methyl transferase inhibitors. Furthermore, there are treatments aimed at non-motor symptoms, such as psychiatric symptoms, cognitive impairments, autonomic dysfunctions, and sleep disorders. For drug treatments, it is advisable to start with a low dose and gradually increase to an appropriate dosage while maintaining the medication regimen. Currently, we cannot cure Parkinson's disease; we can only provide relief to the symptoms and slow the progression of the disease through comprehensive treatment. (The use of medications should be under the guidance of a doctor.)
