Parkinson’s disease is a chronic brain disease, it will seriously affect the normal life of patients, but also affects the physical and mental health of patients, Parkinson’s disease should be early detection and early treatment, so it is very important to understand the symptoms of Parkinson’s, and for the Parkinson’s complications caused by the understanding is also very necessary, then, Parkinson’s disease will cause what complications? The symptoms of Parkinson’s disease are stiffness, clumsiness of movement, tremor of the limbs, and the lack of facial expression and the mask face, combined with a single tone of voice, ambiguity, reduced volume, drooling, etc., which makes the patient feel that there is a loss of elegance, in the psychological often have a sense of inferiority, do not want to participate in social activities, do not go to the public places, and alienated from interpersonal communication. In the process of treatment and disease development, there will be some anxiety, depression, insomnia, dementia and other Parkinson’s complications. Parkinson’s disease may also cause injury. With the development of the disease, tremor, rigidity, coordination dysfunction, will gradually involve the motor function, so the complications of Parkinson’s is manifested in the reduction of motor function, which in turn will lead to easy to fall or even fracture and other injuries when the feet meet obstacles. Parkinson’s disease in the late stage to take the brain pacemaker treatment effect is good For early and mid-stage patients, in addition to reasonable drug treatment, should also be encouraged to do more exercise, for advanced Parkinson’s patients to do more passive activities, in order to slow down the limb complications. When patients have severe movement disorders, the degree of improvement that can be given by medication is often very small, and then patients can only achieve certain results through surgical treatment. Brain pacemakers reduce Parkinson’s disease symptoms by implanting electrodes in specific neural nuclei in the patient’s brain and releasing high-frequency electrical stimulation, which inhibits the electrical impulses of these over-excited neurons due to the reduction of dopaminergic neurons, and reduces their over-excited state. Brain pacemakers can effectively treat and relieve the three main symptoms of Parkinson’s disease: tremor, rigidity and bradykinesia, and are especially effective in improving midline symptoms such as difficulty in starting, difficulty in turning over, and gait abnormalities.
