Deep brain electrical stimulation is relatively safe. Deep brain electrical stimulation is a long-term drug treatment for Parkinson’s disease. The curative effect is significantly reduced, or patients with serious symptom fluctuations or dyskinesia. Deep brain electrical stimulation can significantly improve motor symptoms, but can not cure the disease. Drug treatment is still needed after operation, but the dose of drug can be reduced. Surgery has a good effect on limb tremor and myotonia, but it has no obvious effect on postural and gait disorders. Deep brain electrical stimulation, as one of the main treatment options, is relatively widely used in clinic because it is relatively noninvasive, safe and controllable.
Deep brain electrical stimulation, also known as brain pacemaker, sends electrical pulses to the relevant nerve nuclei controlling movement through the electrodes implanted in the brain to regulate abnormal neuroelectrical activities, so as to achieve the purpose of treating diseases. Deep brain stimulation is the most widely used in Parkinson’s disease and is now spreading to other application fields. For example, in addition to the treatment of Parkinson’s disease, it can also be used in the treatment of idiopathic tremor, dystonia, mental and psychological diseases, cognitive disorders, epilepsy, consciousness disorders, etc. deep brain stimulation can be tried. Deep brain electrical stimulation in the treatment of Parkinson’s disease has the characteristics of reversible, adjustable, safe and minimally invasive. It can significantly improve the symptoms of motor retardation, dyskinesia, muscle stiffness and tremor in patients with Parkinson’s disease, reduce the dosage of drugs, reduce the side effects of drugs, improve the quality of life and enable patients to return to work.
