First of all the etiology is inconclusive. Currently recognized exposure to pesticides, herbicides (farmers), certain occupations such as miners, stone fighting, and even teachers, and some long-term use of sleeping pills; some studies suggest it is an autoimmune disease. The traditional view is that Parkinson’s disease is caused by degenerative changes in dopaminergic neurons in the substantia nigra. However, recent studies have found that PD is a neurodegenerative disease that accumulates in multiple regions of the central nervous system. According to the Braak hypothesis, PD lesions begin in the olfactory bulb, medulla oblongata and pontine brain; then progress to the substantia nigra and other deep nuclei in the midbrain and forebrain, leading to typical motor symptoms such as tremor, tonicity and reduced movement; and finally progress to the limbic system and neocortex. Clinical work has revealed that PD patients are also afflicted with many non-motor symptoms. These symptoms are the result of disease involvement of non-dopaminergic neurons (cholinergic, adrenergic, pentraxinergic, glutamatergic) and include: 1. Psychiatric: depression, anxiety, cognitive impairment, hallucinations, apathy, sleep disturbances. 2, autonomic: constipation, low blood pressure, hyperhidrosis, sexual dysfunction, urinary disorders, salivation. 3, sensory disorders: numbness, pain, spasticity, restless leg syndrome, olfactory disorders. Parkinson’s disease is a chronic degenerative disease of the central nervous system that occurs in middle-aged and elderly people. The main clinical manifestations are resting tremor, bradykinesia, myotonia and postural gait abnormalities. To maintain the patient’s ability to live independently as much as possible. Compounded levodopa, anticholinergics and dopamine agonists are commonly used. Western drugs have a rapid onset of action and can quickly improve symptoms in patients with initial application. However, there are some problems with western medicine treatment, one is that the initial efficacy is good, but after a period of time the efficacy is not obvious and the dose needs to be increased continuously; the second is that western medicine itself has side effects, if the western medicine treatment can be combined with traditional Chinese medicine, the combination of Chinese and western medicine treatment, often can receive unexpected results. The role of Chinese medicine in the treatment of Parkinson’s disease is mainly reflected in: 1, there is a certain improvement of symptoms: especially for early patients, Chinese medicine has traditionally stressed that “not to treat the disease to cure the disease”, for Parkinson’s disease in the early stages of patient intervention in Chinese medicine treatment, can achieve the purpose of prevention before the disease, early treatment of the disease. 2.Reduce the dosage of western medicine: for patients who are taking western medicine, the dosage of western medicine can be gradually reduced after adding traditional Chinese medicine treatment, and the same efficacy can be achieved as before traditional Chinese medicine treatment. 3.Reducing the side effects of western medicine: long-term use of western medicine such as dopa preparation often has different degrees of side effects, such as digestive system, cardiovascular system, nervous system and other side effects, Chinese medicine can take into account its side effects for treatment and reduce the patient’s pain. 4.Enhance the efficacy of western medicine: when the effect of western medicine is not obvious, the effect is often remarkable after adding Chinese medicine. 5, delay the course of the disease: Parkinson’s disease is a chronic degenerative disease that worsens with aging, there is no reliable way to stop its development, Chinese medicine as a cure, has a certain role in delaying the development of the disease. 6.Enhance physical fitness and resistance to disease: improve the quality of survival of patients. Although sometimes the effect of Chinese medicine is sometimes not significant from the Parkinson’s disease symptom score alone, patients have overall improvement in physical fitness, diet, sleep, intelligence, and mental status, and their quality of life is greatly improved.
