With the advent of an aging society, geriatric diseases are increasing, especially in recent years, the incidence of Parkinson’s is increasing. Many Parkinson’s patients get good results with medication, but as the disease progresses, some patients need to consider surgery when the results are not obvious after medication. When should surgery be considered for Parkinson’s disease? Occurrence of drug on/off phenomenon Once Parkinson’s patients experience a decrease in the effect of medication, the side effects of medication begin, and the drug on/off phenomenon occurs, that is, patients who take medication that is effective and the effect disappears after stopping the medication, and patients feel very uncomfortable, this is the time to consider DBS (deep brain electrical stimulation) surgical treatment. Presence of anisokinesis Movement disorders or inability to move, performing random movements to initiate difficult movements, reduced spontaneous and automatic movements, and reduced movement amplitude. Muscle rigidity, resulting in stiffness of the muscles of the limbs, neck, and face, and a feeling of effort, heaviness, and weakness when moving the limbs. Tremor, which manifests as a slow rhythmic tremor that often starts in one finger and spreads to the entire upper extremity, lower extremity, jaw, mouth, lips and head, etc. Is the later the surgery for Parkinson’s disease, the better? For Parkinson’s patients, it is not wise to have surgery too early or to delay it blindly. Surgery too late is not only less effective in improving motor function, but also more damaging to the patient’s brain. Is the earlier the surgery for Parkinson’s disease, the better? Early Parkinson’s disease and Parkinson’s syndrome Parkinson’s syndrome can be difficult to identify, and Parkinson’s syndrome surgery with swallowing and speech problems as well as balance disorders is not addressed by adjusting stimulation parameters. It is important to note that if a patient is clearly diagnosed with Parkinson’s disease early, the sooner the patient benefits from surgery. DBS surgery is the mainstream surgical treatment for Parkinson’s disease, and is a reversible, adjustable, minimally invasive, and non-invasive method of improving Parkinson’s disease. The treatment method.
