帕金森氏症至今病因未明。用多巴胺激动剂或左旋多巴可能改善其症状,但往往引起运动机能和精神方面的副作用。因此建议在疾病早期每当机体功能严重障碍时,才用左旋多巴治疗。一临床对照研究旨在了解帕氏症早期用司来吉林(Selgiline)或生育酚(两药均是抗氧化剂)。是否可以延缓症状的发展。问题提出的依据是单胺氧化酶的活性以及自由基的形成,促进了多巴胺能神经元的变性,使帕 Parkinson’s disease so far the cause is unknown. With dopamine agonists or levodopa may improve their symptoms, but often cause motor and mental side effects. It is therefore recommended that levodopa be used only when there is a serious impairment of the body function early in the disease. A controlled clinical trial aimed at understanding Selgiline or tocopherol (both anti-oxidants) in the early stages of Parkinson’s disease. Whether it can delay the development of symptoms. The problem is proposed based on the activity of monoamine oxidase and the formation of free radicals to promote the degeneration of dopaminergic neurons so that Pa
