Is Parkinson’s disease common? According to epidemiological surveys, about 1% of the elderly population over 55 years of age has the disease. The incidence rate in developed Western countries is similar to that in China. It is estimated that more than 2.2 million people in China suffer from this disease. Due to the improvement of public health and the aging of the population, the number of people suffering from Parkinson’s disease is gradually increasing. Most patients are epidemic, with only isolated cases being familial. Does Parkinson’s disease affect life expectancy? Parkinson’s disease itself is not a fatal disease and generally does not affect life expectancy. With innovations and improvements in treatment methods and levels, more and more patients are able to maintain a high level of motor function and quality of life for life. Of course, if patients do not receive timely and reasonable treatment, it can easily lead to a decline in physical function and even inability to take care of themselves, and eventually various complications, such as pneumonia and urinary tract infections. Can Parkinson’s disease be prevented? The cause of Parkinson’s disease is still unknown, but many studies have shown that it may be related to environmental toxins. Also, people with Parkinson’s disease in their family should be more aware. If someone has Parkinson’s disease in their immediate family, they may have a greater chance of developing Parkinson’s disease. So special attention should be paid to avoiding exposure to some environmental risk factors, such as pesticides, pesticides, heavy metals and manganese, and people with relatives who have Parkinson’s disease should avoid welding jobs. How fast does Parkinson’s disease progress? The progression of each person’s disease is different and varies greatly among individuals. Some few patients progress rapidly to disability within a year, while many patients progress relatively slowly and can maintain better function for 15 to 20 years after reasonable treatment. This is not only related to Parkinson’s disease itself, but also depends largely on the patient’s own psychological quality, medical conditions and family care. Those patients who maintain an optimistic mood, strong will and have harmonious family relationships and good home care, together with reasonable and timely medical treatment, can mostly maintain long-lasting self-care ability and relatively slow progression of the disease. Is Parkinson’s disease an Alzheimer’s disease? Parkinson’s disease mainly affects the patient’s physical mobility, but most patients have normal thinking and clear intelligence, while patients with Alzheimer’s disease have increasing forgetfulness, mental deterioration, and even personality changes. However, some people with Parkinson’s disease may develop symptoms of Alzheimer’s disease in the later stages of the disease. Is Parkinson’s disease hereditary? Current research shows that 5-10% of Parkinson’s disease has a genetic predisposition. Several genes have been identified that can cause Parkinson’s disease in young people, but most people with Parkinson’s disease do not have genetic mutations. Some studies have shown that people with Parkinson’s disease have a genetic susceptibility. How do pacemakers treat Parkinson’s disease? A brain pacemaker, academically known as deep brain stimulation (DBS), eliminates the symptoms of Parkinson’s disease by sending a weak electric current to stimulate the nerves in the brain that control movement and inhibit the abnormal brain nerve signals that cause Parkinson’s disease symptoms, thus restoring the patient’s ability to live and care for himself or herself. Before performing DBS, a stereotactic head frame is installed, and a cranial MRI scan is performed to identify the neural nuclei and the pallidum and thalamic floor nuclei required for the procedure under high-resolution MRI images, and to calculate the 3D coordinates of the head frame required for the procedure. Because of the need to verify the accuracy of the target sites during the procedure, the patient is operated under local anesthesia, i.e., fully awake. As the stimulation electrodes are inserted, the patient’s muscle tone and limb dexterity will improve, at which point the surgeon will further adjust the position and intensity of the electrodes to achieve the best results based on the patient’s perception and the degree of improvement in symptoms. The entire pacemaker system is implanted under the skin of the chest, where a pulse generator (pacemaker battery) is implanted and connected to the electrodes via a subcutaneous lead. The advantages of the pacemaker are less damage, fewer side effects, bilateral implantation, reversible and adjustable, and better control by weak currents outside the body. The vast majority of patients have improved their motor symptoms and quality of life and are able to return to work, and their caregivers are freed from heavy care work and create more social value after receiving pacemaker treatment.
