Brain pacemakers are mainly used to treat primary Parkinson’s disease by stimulating the nucleus accumbens motor nuclei of the brain and treating Parkinson’s patients with tremor, rigidity, and bradykinesia. Brain pacemaker is an electrical stimulator installed in the deep part of the brain, which is commonly used to treat primary Parkinson’s disease. Brain pacemaker is used to stimulate the nuclei of brain movement through long-term neuroelectrical stimulation, and inhibit the electrical impulses of dopaminergic neurons by releasing high-frequency electrical stimulation consciousness through the pulse generator, thus restoring the function of the brain tissues, and treating the resting-like tremor, stiffness, and motor retardation so as to alleviate the symptoms. Brain pacemakers are suitable for patients with severe disease progression, poor drug therapy and low tolerance of side effects. Brain pacemakers can improve the symptoms of pain, bradykinesia, tremor and stiffness, brain pacemakers can only improve the patient’s ability to live, improve the patient’s quality of life, and cannot achieve a complete cure. If a patient needs to undergo pacemaker surgery, he or she should be diagnosed by a doctor and choose a treatment that is appropriate for him or her according to his or her condition.
