What Parkinson's patients does deep brain stimulation apply to?

Parkinson's disease (PD) is a degenerative disease of nervous system, which is common in middle-aged and elderly people. Its clinical characteristics are static tremor, bradykinesia, myotonia and postural balance disorder. The disease progresses slowly and cannot be cured until now. The effect of early drug treatment is remarkable, but the effect of long-term treatment will show obvious decline. At the same time, most patients will show dyskinesia, at this time, surgery can be considered, surgery can choose deep brain electrode stimulation, because of relatively minimally invasive, safe and adjustable. At this stage, it has become the preferred surgical method. However, surgery can only improve symptoms, but not cure the disease, postoperative patients still need to take medication; However, the dosage can be reduced appropriately. Surgery has a good effect on limb tremors or myotonia, but it has no good effect on somatic axial symptoms such as gait disorder.
