Tremor is a common symptom that can be caused by many diseases, but each disease has a different tremor. In general, most tremors do not require specific treatment. Treatment is only needed for patients with clearly diagnosed tremor, such as Parkinson’s disease, with a history of 4-5 years or more, as well as decreasing efficacy for levodopa-based medications, fluctuating symptoms, xerodynia, and significant switching phenomena, which is a better time for surgery. For patients with clearly diagnosed idiopathic tremor, if the efficacy of medication is poor or the side effects of medication are obvious and seriously affect daily work, study and life, surgery is an option. For patients with primary torsional spasm, if medication is not effective, surgery should be performed before it causes limb deformity if possible. For patients with clear diagnosis of Meige syndrome, surgery is not needed for the time being when the symptoms are mild, and medication can be used first; if, as the disease progresses, medication is not effective or the side effects of medication are obvious and seriously affect daily work, study and life, surgery can be chosen. Patients can achieve better treatment results.
